Issuance or Denial of Permit, Conditions and Limitation.

Issuance. Upon receiving an application for grading permit, together with all of the submittals required by Sections 12.44.030(c), (d) and (e) and 12.44.040(e) and (f), the deposit of fees as required by Section 12.44.030(j), and the posting of surety as required by Section 12.44.030(l), the Building Official shall examine the application and related documents, and, if satisfied that the application meets all requirements of this chapter and of other applicable laws, ordinances, rules, and regulations, the Building Official shall issue the permit. The application for a permit shall contain, but shall not be limited to the following provisions:

A provision which requires that pre-construction conference shall be scheduled with all principal decision makers present to discuss and coordinate various aspects of the grading project; A provision which states that the grading shall not be excessive and that the grading shall not go beyond that necessary for the permitted use of the site;
A provision which provides that the slopes can be effectively protected against erosion and slippage; A provision which requires that the finish contours be relatively natural and that the finish contours not distort the natural contours;
A provision which requires that hillside sites be suitable for development in the manner proposed; A provision which mandates that the removal of natural vegetation not be excessive and that the vegetation removal be done in a manner which will minimize erosion;
A provision which requires that drainage not be constructed or directed in a way which damages other property or increases erosion.

The permit that is issued pursuant to this section shall be issued only to the owner or his agent. The permit shall be kept on site, securely displayed in a conspicuous location.

Grounds for Permit Denial.

Hazardous Grading. The Building Official shall not issue a permit where the determination is made that the work as proposed by the applicant has the potential to endanger any public or private property through grading or removal of vegetation or result in the deposition of debris on any public or private way or interfere with any existing drainage course or alter water quality. If it can be shown to the satisfaction of the Building Official that the hazard can be essentially eliminated by the construction of retaining structures, buttress fills, or drainage devices, or by other means, the Building Official may issue the permit with the condition that such work be performed.

Geological or Flood Hazard. If, in the opinion of the Building Official, the land area for which grading is proposed is subject to geological or flood hazard to the extent that no reasonable amount of corrective work can eliminate or sufficiently reduce the hazard to human life or property, the grading permit shall be denied.

Noncompliance With Land Use Conditions. The Building Official shall not issue a grading permit for work that does not or has no reasonable expectation to comply with conditions of approval imposed on a project, the provisions of this Code, or any condition imposed by the approving authority on approval of the use.

Existing Building Code or Zoning Ordinance Violations. The Building Official shall not issue a grading permit if any building code or zoning ordinance violation exists on the site.

Limitations of Permit. The issuance of a permit under this chapter shall constitute an authorization to do only that work which is described or illustrated on the application for the permit or on the site plans and specifications approved by the Building Official.

Compliance with Plans and Requirements. All permits issued hereunder shall be presumed to include the provision that the applicant and their agents, contractors and employees shall carry out the proposed work in accordance with the approved plans and specifications and in compliance with all the requirements of this chapter.

Time Limits. The permittee shall fully perform and complete all of the work required to be done pursuant to the grading permit within the time limit specified. If no limit is specified, the permittee shall complete the work within one hundred eighty (180) days after the date of the issuance of the grading permit.

If unable to complete the work within the specified time, the permittee shall request, prior to the expiration of the permit, in writing to the Building Official for an extension of time, setting forth the reasons for the requested extension. If, in the opinion of the Building Official, such an extension is warranted, the Building Official may grant additional time for the completion of the work for which additional fees may be applicable. Denial of an extension of time shall not preclude the right of the permittee to apply for a new permit for the remaining balance of the work. Written consent of the surety to any extension of time must be furnished before the approval of the extension becomes effective, unless the security consists of a cash deposit.

Liability and Hold Harmless. Neither the issuance of a permit under the provisions of this chapter, nor the compliance with the provisions thereof or with any conditions imposed in the permit issued hereunder, shall relieve any person from responsibility for injury to people or damage to property. The permittee shall execute a hold harmless clause on the permit which shall read as follows:

The permittee, for themselves, their contractors, and employees, agrees to save, indemnify, defend, and hold harmless the City of Richmond and its officers, employees, and agents from all liabilities and claims for damages by reason of injury or death to any person or persons or damage to property from any cause whatsoever while in, upon, or in any way connected with the work covered by this grading permit.

Jurisdiction of Other Agencies. Permits issued under the requirements of this chapter shall not relieve the permittee of any requirements or responsibilities for fully conforming to any other requirements for the work to be done, including but not limited to securing permits and licenses established by any law, ordinance, rule, or regulation of the City of Richmond, or employee thereof, or of any other Public Agency having jurisdiction over such work.

Fees. Fees shall be collected by the Building Official as established by a resolution of the City Council.

Refunds.

Filing fees, permit transfer fees, penalty fees and site investigation fees are not refundable.

In cases of a reduction of planned work, the approval of an amended permit by the Building Official and satisfactory completion of the work covered by an amended permit, the permittee may apply to the Building Official within thirty (30) days after issuance of the certificate of completion for a refund of a portion of the permit fee based on the revised cost of the work in the amended permit.

Surety.

Surety Required. If the Building Official determines that the nature of the proposed work is such that, if left incomplete, it will interfere with any natural or artificial drainage, or will endanger persons or public or private property, or will constitute a nuisance or if he determines that the proposed work involves the removal or deposition of more than fifty (50) cubic yards of material, the applicant for the grading permit shall post with the Building Official a surety executed by the applicant and secured, at the option of applicant, by A corporate surety bond executed by a surety company authorized to do business in the State of California; or By deposit with the City of Richmond of cash money or its equivalent; or By deposit with the City of Richmond of an instrument of credit from a financial institution subject to regulation by the State of California or the federal government pledging that the funds necessary to meet the performance are on deposit and guaranteed for payment upon demand and agreeing that the funds designated by the instrument shall be trust funds for the purposes set forth in the instrument. The form of the bond and the security shall be subject to approval by the Building Official and the City Attorney.

Amount of Surety. The amount of the surety shall be based upon the cost of the total number of cubic yards of material moved, plus the cost of all drainage erosion control or other protective devices or work necessary to eliminate geological hazards or to protect persons or public or private property. The amount of surety shall reflect market value to perform subject work or revert site back to original condition.

When the rough grading has been completed in conformance with the requirements of this chapter, the Building Official may, at the Building Official's discretion, consent to a proportionate reduction of the surety to an amount estimated to be adequate to insure completion of the grading work, site development, or planting remaining to be performed. The costs referred to in this section shall be as estimated by the Building Official.

Conditions of Surety. Among other appropriate provisions, every bond shall include the following conditions to which the principal and surety shall each be bound:

To comply with all of the provisions of this chapter and all other applicable laws, ordinances, rules, and regulations; To comply with all of the terms and conditions of the permit for excavation or fill to the satisfaction of the Building Official; To co
mplete the work contemplated under the permit within the time limit specified in the permit. (The Building Official may, for sufficient cause, extend the time specified in the permit, but no such extension shall release the surety;) To pay all reasonable costs incurred or expended by the City of Richmond, including but not limited to court costs and attorney's fees, in doing or causing to be done any of the work set forth in the permit, any other work which in the judgment of the Building Official is required to be done as a result of any work or activity done under the permit, or any abatement of any nuisance created by any work or activity done under the permit, or in collecting money or damages in connection with any of the foregoing.

Term of Surety. The term of the bond shall begin on the date of its posting and shall end on the satisfactory completion of the terms and conditions of the permit. Completion shall be evidenced by a certificate of completion to be issued by the Building Official and filed with the records of the permit. A copy of the certificate shall be furnished to any interested party upon request.

Notice of Default. Whenever the Building Official finds that a default has occurred in the performance of any term or condition of any permit, he shall give written notice thereof separately to the permit holder and to his surety. Such notice shall state the work or other things necessary to be done in order to cure such default, its estimated cost, if known, and the period of time deemed reasonably necessary by the Building Official to complete such work, and to do such other things which are necessary to be done in order to cure such default. Such notice shall be served personally or by deposit in the United States mail in a sealed envelope, with postage fully prepaid, addressed to the permit holder and to his surety at the mailing address, or, if there is no mailing address, the business address, shown in the application or in the surety, as the case may be.

Duty of Surety. Upon service of the notice of default, the surety shall be obligated to have the work done within the time specified in the notice.

Disposition of Cash Security. If cash money or its equivalent or an instrument of credit has been deposited to secure the bond, and if notice of default has been served upon the permit holder and he has failed to do the work and other things required to be done by the notice within the time specified in the notice, the Building Official may use such deposit in order to have such work and other things done, by contract or other means in the discretion of the Building Official. The balance, if any, shall be returned to the depositor after completion of the work and other things.

Right of Entry. In the event of any default in the performance of any term or condition of the permit, the surety, if any, or any person employed or engaged on its behalf, or the Building Official or any person employed or engaged on his behalf, shall have the right to go upon the premises to complete the work and do other things required by the permit. It shall be unlawful for any person in any way to hinder, obstruct, or prevent such entry.

Erosion and Sediment Control Surety. If a grading permit requires the preparation of an Erosion and Sediment Control Plan, the applicant shall secure the performance of the work described and delineated in the plan as follows:

The Building Official shall review the Interim and Final Erosion and Sediment Control Plans and estimate to determine the bond amount to cover the Erosion and Sediment Control Plans, their implementation and maintenance. If the approved engineer's estimate of cost of the Erosion and Sediment Control Plans is less than ten thousand dollars ($10,000), a cash bond in that amount is to be provided to the City. If the approved engineer's estimate of cost of construction of the Erosion and Sediment Control Plans is more than ten thousand dollars ($10,000), then a cash bond of at least ten thousand dollars ($10,000) shall be posted with the City to cover the work outlined in the Erosion and Sediment Control Plans. After reviewing the grading plans and the Erosion and Sediment Control Plans, the Building Official shall determine the final amount of the cash bond. If permanent site landscaping is an element of the Final Erosion and Sediment Control Plan, then the value of that improvement may be deducted if a separate landscape surety is being required.

When a cash bond amount has been determined, the differences between the cash bond and the total surety requirement shall be provided to the City in the form of bonds or other surety acceptable to the City Attorney. As part of the Erosion and Sediment Control Plan, the applicant shall submit a time schedule outlining specific dates when each element of the plan is proposed to be completed. After the schedule has been agreed to by both the City and the applicant, this schedule shall be the triggering mechanism for the City performing the work in lieu of the applicant's contractor. If the contractor has not or cannot install the Interim and Final Erosion and Sediment Control Plan items by scheduled dates, the City, at its option, can install the items necessary to protect the project site and other property. Such items of work shall be paid for from the applicant's cash deposit.

In addition, any items of Erosion and Sediment Control Plan work that have been installed and are not being adequately maintained to protect the site as determined by the Building Official shall be remedied, and any associated cost shall be paid for from the applicant's cash bond. During storm periods, if the applicant's contractor cannot be contacted or cannot perform required work needed to protect the site as determined by Building Official the City shall cause the work to be performed and any associated costs shall be paid from the applicant's cash bond.

In accepting the grading permit, the applicant acknowledges the right of the City or its representative to come on to the applicant's property to perform any or all needed work, as previously outlined in this section.

Notice of Default. Whenever the Building Official finds that a default has occurred in the performance of any term or condition of any permit, the Building Official shall give written notice thereof separately to the permit holder and to the permit holder's surety.

Such notice shall state the work necessary to be done in order to cure such default, its estimated cost, if known, and the period of time deemed reasonably necessary by the Building Official to complete such work, and to do such other things which are necessary to be done in order to cure said default. Such notice shall be served personally or by deposit in the United States mail in a sealed envelope, with postage fully prepaid, addressed to the permit holder and to his surety at the mailing address; or, if there is no mailing address, the business address, shown in the application or in the bond, as the case may be.

If any part of the cash bond needs to be expended by the City to undertake work items outlined in subsection (l)(9)(b) of this section, the associated grading permit is automatically terminated. The applicant shall submit a new grading permit application, a new grading plan with an Erosion and Sediment Control Plan acceptable to the Building Official and provide the appropriate bonds and fees required by the City. There is no guarantee that a new permit will be issued.

When all grading as shown in the approved grading plans has been completed, and all items of work in the Erosion and Sediment Control Plan have been installed to the satisfaction of the Building Official, the applicant may request exoneration of grading and Final Erosion and Sediment Control Plan bonds. The Building Official shall review all requests for exoneration of grading bonds, but Final Erosion and Sediment Control Plan bonds shall not be considered for exoneration until the site has weathered a storm season from October 1st to April 15th with Final Erosion and Sediment Control Plan elements including permanent landscaping in place. The Building Official can, upon request, make a determination on minor grading projects whether or not the Erosion and Sediment Control Plan bonds need to be held through a storm season.

Job Plans. When an application is approved and a permit issued, one set of plans and accompanying documents shall be clearly marked as appr
oved and shall be returned to the applicant. This set shall be kept available for reference at the job site during grading and construction.

The applicant may furnish additional sets of plans and documents for notation as reviewed for return to the applicant for his use.

The Building Official may amend the permit to approve altered plans, or may deny approval of the changes.

Failure to obtain prior approval for any change in the work shall be cause for the Building Official to order suspension of all work until approval is obtained, and may result in revocation of the permit if he deems the changes will increase the hazard to adjoining properties or public roads, or otherwise be detrimental to public welfare.

Transfer of Permit.

Any transfer of a permit from the permittee to another party is prohibited unless approved by the Building Official.

The transferee shall agree to comply with the requirements and conditions of the original permit and to any modification thereof that may be required because of changes in the condition of the site or change in plans since the permit was issued. The transferee shall furnish the required sureties before the transfer of the permit will be approved.

Suspension and Revocation of Permit.

Grounds. A permit may be suspended or revoked if the Building Official finds that:

Conditions at the site vary appreciably from those shown and stated in the application and development plans; Grading or construction does not conform to the approved plans, grades, Interim or Final Erosion and Sediment Control Plan, or other conditions of the permit;
Cessation of work before completion that has left the site in a condition hazardous to the public or to the adjacent properties, and the permittee has not complied with reasonable requirements for completion of the work within the time specified in the permit or an approved extension of time;
The permittee does not comply with reasonable requirements to safeguard the workers, the public, or other persons acting in a lawful manner, during grading or construction operations; In transporting materials or in the operation of equipment the applicant causes materials or litter to encroach, obstruct, or be deposited on pavement or in drainage channels within the public right-of-way, or causes unauthorized obstruction or diversion of drainage channels within the site area; or
The permittee fails to have a qualified inspector working under the geotechnical engineer on the site during grading or construction, when required, or failure to have the work under proper supervision at all times.

Procedure. Upon determination that grounds for revocation or suspension of a grading permit exist, the Building Official may fix a time and place for a hearing on revocation or suspension and shall give written notice thereof separately to the permit holder and to the surety, if any, stating in general terms the grounds for revocation or suspension. Such notice shall be given at least five (5) days before the hearing, and it shall be served personally or by deposit in the United States mail in a sealed envelope, with postage fully prepaid, addressed to the permit holder and to his surety at the mailing address, or, if there is no mailing address, the business address, as shown in the application or in the bond, as the case may be.

Within thirty (30) days of the conclusion of the hearing, the Building Official shall make his findings and decision and file same in his office and shall serve a copy thereof separately upon the permit holder and his surety, if any, in the manner provided above for service of notice of hearing.

Exception. If the Building Official determines that emergency conditions exist on the site which constitute a threat to the public health, safety, and welfare, the grading operation in its entirety or portion thereof shall immediately cease.

Notice to Cease Work.

Upon notification from the Building Official of the suspension of the permit, the permittee shall cease all work in connection with the permit with the exception of the work necessary to correct the conditions which caused the suspension of the permit. The permittee shall proceed at once to correct such objectionable or emergency conditions.

If the permittee fails to correct such objectionable or emergency conditions, the Building Official may cause the work necessary to correct said conditions to be done, and the Building Official may take action against the permittee's surety to cover the cost of performing the work.

Any permit which has been suspended may be either reinstated or revoked by the Building Official.

Whenever a permit has been revoked, work shall not commence until a new application has been filed and approved incorporating the necessary revisions required to fulfill the intent of this chapter, and a new permit has been issued.

12.44.040 - Control of work.

City Inspection. The Building Official and other authorized City representatives shall have the right to enter the site at all times to insure compliance with permit conditions.

Supervised or Regular Development Work. All work involving a fill intended to support improvements, or grading where the Building Official determines that special conditions or unusual construction hazards exist, shall be performed under the inspection of a civil engineer and/or geotechnical engineer and shall be designated "supervised development work." Work other than supervised development work shall be designated "regular development work."
Inspection and Reports of Regular Development Work.

For regular development work the Building Official or designated representative, upon notification from the permittee or his agent, shall inspect the work at the following stages of the work and shall either approve the portion then completed or shall notify the permittee or their agent of the inspection results.

Initial. When the site has been cleared of vegetation and unapproved fill and has been scarified, benched or otherwise prepared and before any fill is placed.

Rough. When rough grading has been completed and approximate final elevations have been established; drainage terraces, swales and other drainage devices have been graded and are ready for paving; and berms have been installed at the top of slopes.

Interim Erosion and Sediment Control Inspection.

Site Observation. Between October 1st and April 15th, an inspector shall visit the site a minimum once a day. A log will be kept indicating the time of inspection, and relevant comments on progress and site conditions. During storm periods, an inspector shall visit the site twice a day including weekends and shall be accompanied by the contractor's superintendent and shall check as a minimum the following items:

V-ditches shall be checked for proper operation (i.e., flow, silt build-up, deterioration of banks); Straw bales shall be checked for silt build-up and bales removed or replaced as necessary; Sand bags shall be checked for damage and silt plugged bags replaced as needed; Detention/retention basins shall be checked for damages and silt removed periodically as determined necessary; Overflow spillways shall be checked for proper operation; Filter fabric shall be checked. Plugged and damaged fabric shall be replaced as necessary.

The time of inspection, the personnel visiting the site, the condition of the site and the adequacy of the erosion control facilities shall be logged.

If corrections need to be made to protect the site, the items of work and time scheduled to perform the work by the contractor shall also be noted.

Interim and Final Erosion Control Measures. Erosion control measures shall be installed for all rainy season active and passive construction projects. Grading operations may commence in or continue through rainy season, at the discretion of the Building Official, provided that erosion control measures in conformance with approved plans are immediately installed and are kept continuously in place, as the case may be. The only control measures which may be altered are those in direct conflict with daily construction activity, as long as such controls are replaced at the end of construction activity that day or start of storm event. Erosion control measures shall include, but not necessarily be limited to, the following:

The Erosion and Sediment Control Handbook and California Storm Water Best Management Practices Hand Book shall be used as guides for the design and suitability of erosion and sediment control measures.

The faces of cut and fill slopes shall be protected against damage by erosion and the methods utilized for each protection must offer effective erosion control prior to the beginning of, as well as during, the rainy season.

Where graded slopes are steeper than three (3) feet horizontal to one (1) foot vertical or are higher than ten (10) feet, they shall be protected with a temporary soil stabilization measure such as jute matting or an equivalent mulch until planting is established.

The surface of all cut slopes higher than five (5) feet and all fill slopes higher than three (3) feet shall be permanently protected against damage by erosion by the planting and establishment of protective vegetation.

Slopes higher than fifteen (15) feet shall be planted with one shrub per one hundred (100) square feet of slope and one (1) tree per four hundred (400) square feet of slope. Geometric spacing should be avoided. Massing of trees is encouraged. Size and species of plant material shall be subject to review.

The planting of seeding or vegetation protection must be effective. If the vegetation does not grow and offer proper protection, it must be replanted or reseeded.

The maintenance of vegetative protection on graded slopes shall be the responsibility of the permittee and shall be guaranteed until the vegetation is well established as determined by the Building Official or until the maintenance is officially assumed by another party approved by the Building Official.

Sediment control facilities shall be operational prior to the beginning of the rainy season and must effectively prevent sediment from being transported downstream.

The outlet from any sedimentation basin must be designed to handle 1.5 times the maximum design inflow.

A standby emergency crew must be provided by the permittee and must be available at all times during the rainy season to repair and maintain the erosion and sediment control devices.

Erosion control materials must be stockpiled on the site for emergency repairs during the rainy season.

Trunk storm drain facilities, if determined by the Building Official to be essential to the operation of the erosion control measures, shall be installed in place with grading operations and shall not be delayed until grading completion.

After each rainfall, the permittee shall inspect all erosion and sediment control devices and shall clean them and repair any damage.

Erosion control devices must be installed where drainage facilities discharge into natural channels. The devices may be rip-rap or concrete channel protection, stilling basins, check dams, drop structure or other devices which will effectively minimize erosion in the opinion of the Building Official.

Erosion Control Planting as set forth in Section 12.44.060(g).

Notification of Noncompliance. If the soil or civil engineer finds that the work is not in conformance with this chapter or with the plans approved by the Building Official, or with good accepted practices, they shall immediately notify the permittee and the Building Official verbally and in writing of the nonconformity and of the corrective measures to be taken.

Termination of Services. If the civil engineer, or the geotechnical engineer, or the geologist are relieved of or otherwise terminates duties prior to completion of the work shown on the grading plan, they shall report the fact in writing to the Building Official within forty-eight (48) hours with a report on the status of the work.

Compliance With Laws. In addition to the requirements of the permit, the permittee shall comply with all laws, ordinances, and regulations of the State Department of Industrial Relations, relating to the character of the work, equipment, and labor personnel involved in the project.

Cessation of Work. If the permittee ceases work for any reason before the work is completed, all necessary steps shall be taken to leave the premises in a condition that will be safe and will not cause damage to adjoining properties or to the public roads or to any natural or artificial drainage facilities through erosion of materials, landslides, or other instability of slopes and materials.

Certificate of Completion. The Building Official shall issue a certificate of completion upon satisfactory completion of work under an approved permit.

The geotechnical engineer and/or engineering geologist must certify that all compaction requirements have been complied with and sub-drains are located where shown on plans or plans are modified, as the case may be.

A licensed surveyor or registered civil engineer authorized to do survey work must certify that the horizontal and vertical controls conform to the plans or any approved changes to them.

The Building Official must be in receipt of a set of mylar plans which include all details of the grading operation and related details.

12.44.050 - Safety and general requirements.

General Safety Precautions.

Adequate provisions shall be made to prevent any surface waters from damaging the cut face of an excavation or sloping surface of a fill. Retaining walls or cribbing constructed in accordance with the requirements of the Building Official shall be used wherever necessary to prevent the surface of any excavation or fill from exceeding at any point the maximum allowable slopes set forth herein.

All site drainage shall be conveyed to the nearest adequate storm drain, natural watercourse, or street approved by the Building Official as appropriate to deposit and receive such waters.

Storm Damage Precautions. All persons performing any grading operations shall put into effect all safety precautions which are necessary in the opinion of the Building Official and shall remove all loose dirt from the grading site and provide adequate anti-erosion and/or drainage devices, debris basins, or other safety devices to protect the life, limb, health, and welfare of private and public property of others from damage of any kind.

Protection of Utilities. During grading operations the permittee shall be responsible for the prevention of damage to any public utilities or services. This responsibility applies within the limits of grading and along any routes of travel of equipment.

Protection of Adjacent Property.

No excavation shall be made sufficiently close to the property line to endanger any adjoining public street, sidewalk, alley, or other public property or any adjoining private property without supporting and protecting such adjoining public or private property from settling, cracking or other damage in a manner approved by the Building Official.

No person shall grade, whether or not a permit is required therefor under this chapter, so that dirt, soil, rock, debris, or other material washed, eroded, or moved from the property by natural or artificial means creates a public nuisance or hazard, or an unlawful encroachment on private property or on a public road or street. Any such material deposited within the right-of-way of a public road or street which may constitute a nuisance or hazard to public traffic shall be removed immediately, and failure to do so on notice from the City authorizes the City to have the material removed at the expense of the permittee.

Whenever any portion of the work requires entry onto adjacent property for any reason, the permit applicant shall obtain the written consent of the adjacent property owner or their authorized representative, and shall file a copy of such consent with the Building Official before a permit for such work may be issued.

Removal of Ground Cover. Removal of ground cover shall be performed pursuant to the requirements set forth in Section 12.44.030(e).

Water Obstruction. No person shall obstruct, impede or interfere with the natural flow of storm waters, whether unconfined upon the surface of the land, within land depressions or natural drainage ways, within unimproved channels or watercourses, or within improved ditches, channels or conduits, except for construction operations permitted by the City.

Levees. No person shall do any grading work on any levee without approval of the governmental agency responsible for the maintenance of the levee.

Public Rights-of-Way. No person shall perform any work or construct any facility (including excavation or embankment, trenching, driveway construction, or drainage facility) within the right-of-way of a public road or street, or within an easement under the jurisdiction of this City, without a permit from the City.

Precautions Imposed by Building Official. If, at any stage of grading, the Building Official determines by inspection that the nature of the construction is such that further work as authorized by an existing permit is likely to endanger any property or public way, the Building Official may require as a condition to allowing the work to be continued that such reasonable safety precautions be taken as the Building Official considers advisable to avoid such danger. Remedial actions may include but shall not be limited to specifying a flatter exposed slope, construction of additional drainage facilities, berms, terracing, compaction, cribbing, or retaining walls, or planting of slopes.

Abatement of Hazardous Conditions. Whenever the Building Official determines that any existing excavation or embankment or fill has become a hazard to life and limb, or endangers property, or adversely affects the safety, use, or stability of a public way or drainage channel, the owner of the property upon which the excavation or fill is located, or other person or agent in control of such property, upon receipt of notice in writing from the Building Official shall within the period specified therein repair or eliminate such excavation or embankment so as to eliminate the hazard and be in conformance with the requirements of this chapter,

12.44.060 - Design standards and grading regulations.

General Design Intent. It is the general intent of the regulations of this Chapter that site development design shall preserve to the extent that is reasonable and feasible the existing natural scenic value of hills and valleys and contours of land.

General Criteria for Design. All site development work, whether or not a permit is required under this chapter, shall be designed to:

Retain trees and other native vegetation which stabilizes steep hillsides, retains moisture, prevents or minimizes erosion, and enhances the natural scenic beauty, insofar as practical;

Place building pads in such a manner as to permit ample room for adequate landscaping and drainage between and around the buildings;
Minimize scars from cuts and fills and avoid permanent scarring of the hillsides; Round off, in a natural manner, sharp angles at the top and toe of cut and fill slopes, and conform to existing terrain, both with respect to building sites and to road cross-sections;
Limit development on steep or dangerous terrain;
Take into consideration geologic hazards and adverse soil conditions and their effect on the future stability of the development.

Regulations for Excavations.

Maximum Slope. Cuts shall not be steeper in slope than two (2) horizontal to one (1) vertical unless the owner furnishes a soil or a geological report certifying that the site has been investigated and indicating that the proposed deviation will not endanger any public or private property or result in the deposition of debris on any public way or place or interfere with any existing drainage course.

The Building Official may require the excavation to be made with a cut face flatter in slope than two (2) horizontal to one (1) vertical if he finds it necessary for stability and safety.

Drainage Terraces. Cut slopes exceeding thirty (30) feet in vertical height shall have drainage terraces not less than eight (8) feet in width, measured from the outer edge of the terrace to the invert of the drain, at vertical intervals not to exceed twenty-five (25) feet except that where only one (1) such terrace is required it shall be located at mid-height. For cut slopes exceeding one hundred (100) feet in vertical height, the drainage terrace near mid-height shall be not less than twelve (12) feet in width. Design and construction of drainage terraces shall conform to the requirements of Section 12.44.060(f). All cut slopes shall be examined for evidence of seepage at completion of grading to determine if installation of horizontal drains is necessary.

Variations. Variations from the regulations in this section may be allowed by the Building Official if the variations will provide equivalent safety, stability, and protection against erosion, as recommended by a geotechnical engineer or engineering geologist.

Regulations for Fills.

Compaction. Except as otherwise provided in subsection (d)(2) of this section, all fills shall be compacted throughout their full extent to a minimum of ninety percent (90%) of maximum density as determined by the current ASTM D1557 test method. Field density shall be determined by a method acceptable to the Building Official. All existing on-site fills and backfills shall be excavated and stockpiled for reuse in planned fill areas.

Exceptions to Compaction Requirement.

Special Compaction. Compaction may be reduced to eighty-five percent (85%) of maximum density as determined by the specified test in subsection (d)(1) of this section, within the outer eight (8) inches of fill slope surfaces when such compaction is provided by grid rolling or equivalent means.

Nonstructural Fills. Fills not intended to support structures, subdivision streets or improvements need not be compacted to the standard set forth in subsection (d)(1) of this section if the Building Official determines that such compaction is unnecessary as a safety measure. In making this determination, the Building Official may require that an investigation be made by an approved soil testing agency to establish the characteristics of the soil, the amount of settlement to be expected and the susceptibility of the soil to erosion or slippage.

Planted Slopes. Slope surfaces may be prepared for planting by scarifying, by the addition of topsoil, or by other methods, if such loose material does not exceed a depth of three inches and said slopes otherwise comply with the requirements of this section.

Preparation of Ground. The natural ground surface shall be pared to receive fill by removing vegetation, noncomplying fill, topsoil, and, where slopes are five (5) horizontal to one (1) vertical or steeper, by benching into sound bedrock or other competent material. Five (5) feet of the lowermost bench shall be exposed beyond the toe of the fill. The bench shall be sloped for sheet overflow or a paved drain shall be provided.

Fill Slope. No compacted fill shall be made which creates an exposed surface steeper in slope than two (2) horizontal to one (1) vertical. The Building Official may require that the fill be constructed with an exposed surface flatter than two (2) horizontal to one (1) vertical if he finds this necessary for stability and safety.

Fill Material. No organic or other reducible material shall be incorporated in fills. Except as recommended by the geotechnical engineer and approved by the Building Official, no rock or similar irreducible material with a maximum dimension greater than four (4) inches shall be buried or placed within forty-eight (48) inches of finish grade. Expansive adobe soils shall not be used in fills within five (5) feet of finish grade in street and building areas and shall not be placed in the slope area of high fills.

Drainage Terraces. Fill slopes exceeding thirty (30) feet in vertical height shall have drainage terraces not less than eight (8) feet in width, measured from the outer edge of the terrace to the invert of the drain, at vertical intervals not exceeding twenty-five (25) feet except that where only one (1) such terrace is required it shall be located at mid-height. For fill slopes exceeding one hundred (100) feet in vertical height, the drainage terrace near mid-height shall be not less than twelve (12) feet in width. Design and construction of drainage terraces shall conform to the requirements of Section 12.44.060(f).

Slopes to Receive Fill. Where fill is to be placed above the top of an existing or proposed cut or natural slope steeper than three (3) horizontal to one (1) vertical, the toe of the fill shall be set back from the top edge of the slope a minimum distance of six (6) feet, measured horizontally, or such other distance as may be specifically recommended by a geotechnical engineer or engineering geologist and approved by the Building Official. Fills shall not toe out on slopes steeper than three (3) horizontal to one (1) vertical.

Slope Location and Setbacks.

The property line of any proposed or existing site or parcel located within the grading project shall be located at the top of the slope or along any slope drainage terrace.

Excavation and fill slopes shall be set back a minimum of three (3) feet plus one-fifth (1/5) the vertical height of the slope from the project boundary line, with a maximum of ten (10) feet.

Buildings and structures shall be set back from excavation or fill slopes a minimum of four (4) feet plus one-fifth (1/5) of the vertical height of the slope, with a maximum of ten (10) feet.

Variations from the regulations in this subsection (e) may be allowed by the Building Official if they will provide equivalent safety, stability, and protection against erosion, as recommended by a geotechnical engineer or engineering geologist.

General. Storm drainage structures, systems and facilities shall be provided as required by the Building Official and in accordance with standard specifications on file with the Building Official. In addition, storm drain structures, systems and facilities shall be in compliance with State and Federal National Pollution Discharge Elimination System (NPDES) requirements. In satisfaction of these requirements, the Building Official may require the installation of grease traps, sediment basins, storm water monitoring stations and such other devices and systems which the Building Official determines are necessary for compliance with NPDES requirements. The design of all storm drainage structures, systems and facilities shall be in accordance with recognized principles of hydraulics. Such devices shall be considered components of the Final Erosion and Sedimentation Control Plan.

Disposal. All drainage facilities shall be designed to carry surface waters to the nearest practical street, storm drain, or natural watercourses, approved by the Building Official as appropriate to discharge such waters. If the drainage device discharges onto natural ground, rip-rap or a similar energy dissipator may be required. City standard curbs and gutters shall also be installed at the property line adjoining the public right-of-way for the purpose of conveying site runoff to storm drain facilities.

Site Drainage. Graded building sites (building pads) shall have a minimum slope of one percent (1%) towards a public street or drainage facility approved to receive storm waters. A lesser slope may be approved by the Building Official for sites graded in relatively flat terrain, or where special drainage provisions are made, when he finds such modification will not result in unfavorable drainage conditions.

Terrace Drains.

All unlined swales or ditches on drainage terraces shall have a uniform longitudinal grade of not less than one percent (1%) nor more than three percent (3%) and a minimum depth of one (1) foot at the shallowest point. Such terraces shall drain into a paved gutter, pipe or approved watercourse adequate to convey the water to a safe disposal area.

The geotechnical engineer may approve steeper slopes based on sediment transport analysis.

The drainage terrace shall be provided with a lined ditch, if required by the geotechnical engineer for stability or prevention of erosion.

Overflow Protection. Berms, swales or other devices shall be provided at the top of cut or fill slopes to prevent surface water from flowing over or onto, and damaging the face of the slope. Special drainage provisions shall be made where a building or structure exists within five (5) feet of the top of a slope.

Maintenance of Drainage. The permittee shall maintain drainage facilities, in conformance with the requirements of this chapter, during construction. The owner of the subdivided parcel shall maintain forever such drainage facilities as may be contained in a private storm drain easement.

Subdrains. Subdrains and laterals shall be as determined by the geotechnical engineer. Subdrain designs shall be approved by the Building Official. Provisions shall be made for carrying off collected water from all slopes to suitable disposal points.

Variations. Variations from the regulations of this section may be allowed by the Building Official if they will provide equivalent safety, stability, and protection against erosion and storm water pollution as recommended by a geotechnical engineer or engineering geologist and by the Contra Costa County Flood Control District.

Erosion Control Planting.

The surface of all erodible cut slopes more than five (5) feet in height and fill slopes more than three (3) feet in height shall be protected against erosion by planting with landscape materials as prescribed in Section 12.44.030(e). The plants and planting methods shall be suitable for the soil and climatic conditions of the site and in accordance with standard specifications on file with the Building Official.

Irrigation System.

Planted slopes shall be provided with an approved system of irrigation. A functional test of the system may be required. For slopes less than twenty (20) feet in vertical height hose bibs may be allowed where a hose no longer than fifty (50) feet is necessary for irrigation.

The requirements for permanent irrigation systems may be modified, when approved by the Building Official, because the type of plants selected, planting methods used, and soil and climatic conditions at the site make irrigation of the slope planting unnecessary.

Approval. The planting and irrigation system shall be installed after final grading. Final approval of the work and release of the bond shall be made when growth is established on the slopes.

Variations. Variations from the regulations of this subsection may be allowed by the Building Official if the variations will provide equivalent safety, stability, and protection against erosion, as recommended by a geotechnical engineer or engineering geologist.

Other Regulations.

Hours of Work. If operations under the permit are within five hundred (500) feet of residential or commercial occupancies, grading operations shall be limited to the hours between 8 a.m. and 5 p.m. Monday through Friday, or as approved by the Building Official, except that maintenance and service work on equipment may be performed until 9:00 p.m.

Encroachments on Public Rights-of-Way. Encroachment of operations on public rights-of-way without a valid encroachment permit is prohibited except for hauling of legal loads by vehicles permitted by law to operate on public roads.

Nuisances. Operations shall be controlled to prevent nuisances to public and private ownerships because of dust, drainage, removal of natural support of land and structures, encroachment, noise, and/or vibration.

Explosives. Blasting or other use of explosives shall be conducted in accordance with regulations by the City Council, the State Fire Marshal, and local fire authorities.

Responsibility of Permittee.

Compliance With Plans and This Chapter. The permittee, his agent, contractor or employee, shall carry out the proposed work only in accordance with the approved plans and specifications and in compliance with all the requirements of this chapter.

Notice of Work. In performing regular development work it shall be the responsibility of the permittee to notify the Building Official at least one working day in advance so that the required inspections can be made.

Reports Required and Final Approval. The Building Official may require the following reports, as cited in Section 12.44.040(k) and shall not finally approve any development or work until all required maps and reports have been submitted and approved, including the following:

A final report by the civil engineer certifying that all grading, lot drainage and drainage facilities have been completed and the slope planting installed in conformance with the approved plans and the requirements of this chapter with a final contour map if the work is not in substantial conformity with the approved plans.

A report by the geotechnical engineer including the recommended soil-bearing capacity, a statement as to the expansive qualities of the soil, summaries of field and laboratory tests, and his opinion as to the adequacy of the work completed and its conformity with plans and specifications. The location of such tests and the limits of the compacted fill shall also show by plans and cross section the location of any subdrains, rock disposal areas and/or buttress fills in the work.

An engineering geologist's report based on the final contour map including specific approval of the grading as affected by geological factors. The report shall include a revised geologic map and cross sections, with recommendations regarding the location of buildings or sewage disposal systems.

Evaluation of Existing Fill. The Building Official may require the submission of a preliminary soil investigation report and/or engineering geological report before issuing a building permit for a structure to be placed on any fill or embankment constructed before the enactment of this chapter, or excepted from the requirement for a grading permit, or on any other lot or parcel on which critically expansive soils, slide conditions, or other soils, or geologic hazards exist or may reasonably be anticipated to exist. If the Building Official determines that the action recommended in this report is likely to prevent structural damage to the proposed structure, he shall recommend that the requirements contained in the report shall become a part of the required construction as a condition of the permit.

12.44.070 - Appeals.

Any applicant or any permittee or his surety, if any, taking exception to any condition imposed upon his grading permit, or to any denial thereof, or to the revocation or suspension thereof, shall have the right to a hearing before the City Manager, or the City Manager's designee, prior to the implementation of the condition or adverse permit action.

Prior to any denial, revocation or suspension of the permit, the Building Official shall give the appellant written notice of the denial, revocation or suspension. The notice shall set forth the ground or grounds for the denial, revocation or suspension and shall inform the appellant that the appellant has ten days from the date of receipt of the notice to file a written request for a hearing.

Within ten days of the written notice by the Building Official regarding a permit denial, suspension or revocation, or within ten days of receipt of a permit which contains an objected to condition, the appellant may appeal by submitting a request to the Building Official for a hearing before the City Manager, or the City Manager's designee.

SOURCE OF FUNDING
The sewer in this area is old and has tree roots in the pipes, which causes sewer overflows (SSOs). The way the sewers in this area were constructed make maintenance of the system extremely difficult and time consuming.

This project is the realignment of sewer pipes on Tewksbury Avenue, Marine Street, and Morgan Avenue in Point Richmond. Phase I of this project is to install 3 new manholes, install 275 feet of new sewer pipe, and clean out the existing pipe once the new manholes are installed.

SOURCE OF FUNDING
During wet weather, stormwater runoff from the hillside adjacent to the WWTP enters plant storm drains which drain to the sanitary sewer system. During storms, this flow rate can exceed 2 million gallons per day, which: 1) does not need to be treated, 2) adds to amount of blended water discharged to the bay, and 3) limits the capacity of the Wet Weather Storage Facility.

This project is for engineering services to prepare a plan for diverting hillside stormwater runoff so that it does not enter the treatment plant processes.

(ref. SWRCB Order No. 2006 -0003-DWQ Element VI)

1. Purpose

The purpose of the Veolia Water - City of Richmond Overflow Emergency Response Plan (OERP) is to support an orderly and effective response to Sanitary Sewer Overflows (SSOs). The OERP provides guidelines for Veolia Water - City of Richmond personnel to follow in responding to, cleaning up, and reporting SSOs that may occur within the City’s service area. This OERP satisfies the SWRCB Statewide General Waste Discharge Requirements (GWDR), which require wastewater collection agencies to have an Overflow Emergency Response Plan.

2. Policy

City and Veolia Water employees are required to report all wastewater overflows found and to take the appropriate action to secure the wastewater overflow area, properly report to the appr opriate regulatory agencies, relieve the cause of the overflow, and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The City’s goal is to respond to sewer system overflows as soon as possible following notification. City and Veolia Water staff will follow reporting procedures in regards to sewer spills as set forth by the San Francisco Regional Water Quality Control Board (SFRWQCB) and the California State Water Resources Con trol Board (SWRCB) .

3. Definitions As Used In This OERP

BAY AREA CLEAN WATER ASSOCIATION (BACWA): Association comprised of Bay Area wastewater treatment and collection system agencies. BACWA represents the interests of public wastewater agencies in regulatory matters and to support the exchange of information. Website: http://www.bacwa.org BLOCKAGE: An object that partially or fully hinders flow through a sewer pipeline. The blockage can be caused by debris in the sewer, grease buildup, root intrusion, or a partial or full collapse of the pipeline. Also known as a stoppage.

CALIFORNIA INTEGRATED WATER QUALITY SYSTEM (CIWQS) : Refers to the State Water Resources Control Board online electronic reporting system that is used to report SSOs, certify complet ion of the SSMP, and provide information on the sanitary sewer system.

FOG – Fats, Oils, and Grease: FOG refers to fats, oils, and grease typically associated with food preparation and cooking activities that can cause blockages in the sanitary sewer sy stem.

LATERAL OR PRIVATE LATERAL : The privately-owned sewer pipeline that conveys wastewater from the premises of a user to the City’s sewer system. The upper lateral extends from the building to property line (or easement line). The lower lateral extend s from the property or easement line to the connection to the pipe.

LEGALLY RESPONSIBLE OFFICIAL (LRO): Refers to an individual who has the authority to certify reports and other actions that are submitted through CIWQS.

MAINLINE SEWER : Refers to City wastewater collection system piping that is not a private lateral connection to a user.

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 4 MAINTENANCE HOLE OR MANHOLE: Refers to an engineered structure that is intended to provide access to a sanitary sewer for maintenance and inspection.

NOTIFICATION OF AN SSO: Refers to the time at which the City becomes aware of an SSO event through observation or notification by the public or other source.

NUISANCE - California Water Code section 13050, subdivision (m), defines nuisance as anything that meets all of the following requirements:
a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property. b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal. c. Occurs during, or as a result of, the treatment or disposal of wastes.

OVERFLOW EMERGENCY RESPON SE PLAN: This document identifies measures that are needed to respond to sanitary sewer overflows in a way that maximizes the protection of public health and the environment.

PREVENTATIVE MAINTENANCE: Refers to maintenance activities intended to prevent failures of the wastewater collection system facilities (e.g. cleaning, CCTV, inspection).

PRIVATE LATERAL SEWAGE DISCHARGES – Sewage discharges that are caused by blockages or other problems within a privately owned lateral.

ROOTS – Tree root invasion pr esents an additional problem related to FOG (Fats, Oils, and Grease). If a mat of root hair forms in the sewer line it slows the flow of wastewater and exacerbates the rate of accumulation of FOG materials.

SAN FRANCISCO BAY REGIONAL WATER QUALITY CONTROL BOARD: Also known as Region 2 or RWQCB. This regulatory agency preserves, enhances and restores the quality of California's water resources, and ensures their proper allocation and efficient use for the benefit of present and future generations. Website:
http://www.waterboards.ca.gov/sanfranciscobay
SANITARY SEWER OVERFLOW (SSO) - Any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system. SSOs include:
(i) Overflows or releases of untr eated or partially treated wastewater that reach waters of the United States;
(ii) Overflows or releases of untreated or partially treated wastewater that do not reach waters of the United States; and
(iii) Wastewater backups into buildings and on privat e property that are caused by blockages or flow conditions within the publicly owned portion of a sanitary sewer system.

SSOs that include multiple appearance points resulting from a single cause will be considered one SSO for documentation and reporting purposes in CIWQS.

NOTE: Wastewater backups into buildings caused by a blockage or other malfunction of a building lateral that is privately owned are not SSOs.

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 5 SSO Categories :

Category 1: Discharge of untreated or partially treated wastewater of any vo lume resulting from a sanitary sewer system failure or flow condition that either:
• Reaches surface water and/or drainage channel tributary to a surface water; or • Reached a Municipal Separate Storm Sewer System (MS4) and was not fully captured and returned to the sanitary sewer system or otherwise captured and disposed of properly.

Category 2: Discharge of untreated or partially treated wastewater greater than or equal to 1,000 gallons resulting from a sanitary sewer system failure or flow condition that either:
• Does not reach surface water, a drainage channel, or an MS4, or • The entire SSO discharged to the storm drain system was fully recovered and disposed of properly.

Category 3: All other discharges of untreated or partially treated wastewater resulting from a sanitary sewer system failure or flow condition.

SANITARY SEWER SYSTEM : Any publicly -owned system of pipes, pump stations, sewer lines, or other conveyances, upstream of a wastewater treatment plant headworks used to collect and convey wastewater to the publicly owned treatment facility. Temporary storage and conveyance facilities (such as vaults, temporary piping, construction trenches, wet wells, impoundments, tanks, etc.) are considered to be part of the sanitary sewer system, and discharges into these temporary storage facilities are not considered to be SSOs.

SENSITIVE AREA: Refers to areas where an SSO could result in a fish kill or pose an imminent or substantial danger to human health (e.g. parks, aquatic habitats, etc.) SEWER SERVICE LATERAL: Refers to the piping that conveys sewage from the building to the City’s wastewater collection system.

STATE WATER RESOURCES CONTROL BOARD : Also called the State Board. This agency developed and passed the Statewide Waste Discharge Requirements for collection systems and mainta ins the SSO reporting web site.

STATEWIDE WASTE DISCHARGE REQUIREMENTS : The Statewide General Waste Discharge Requirements for Sanitary Sewer Systems was adopted by the SWCRB in 2006 to provide a structure and guidance for SSMP development. Also known as Order No. 2006 -0003-DWQ.

UNTREATED OR PARTIALLY TREATED WASTEWATER: Any volume of waste discharged from the sanitary sewer system upstream of a wastewater treatment plant headworks.

WATERS OF THE STATE : Waters of the State (or waters of the United States) means any surface water, including saline waters, within the boundaries of California. In case of a sewage spill, storm drains are considered to be waters of the State unless the sewage is completely contained and returne d to the wastewater collection system and that portion of the storm drain is cleaned.

4. State Regulatory Requirements for Element 6, Overflow Emergency Response Plan

GWDR Requirement
The collection system agency shall develop and implement an overfl ow emergency response plan that identifies measures to protect public health and the environment. At a minimum, this plan must include the following:
(a) Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner;
(b) A program to ensure appropriate response to all overflows; (c) Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, regional water boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the Monitoring and Reporting Program (MRP). All SSOs shall be reported in accordance with this MRP, the California Water Code, ot her State Law, and other applicable Regional Water Board Waste Discharge Requirements or National Pollutant Discharge Elimination System (NPDES) permit requirements. The Sewer System Management Plan should identify the officials who will receive immediate notification; (d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained;
(e) Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and
(f) A program to ensure that all reasonable steps are taken to contain untreated wastewater and prevent discharge of untreated wastewater to Waters of the United States and minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge.

The Sewer System Management Plan and critical supporting documents are available to the p ublic at www.ci.richmond.ca.us .

5. Goals

The City’s goals with respect to responding to SSOs are:
• Work safely;
• Respond quickly to minimize the volume of the SSO;
• Eliminate the cause of the SSO;
• Prevent sewage system overflows or leaks from entering th e storm drain system or receiving waters to the maximum extent practicable;
• Contain the spilled wastewater to the extent feasible; • Minimize public contact with the spilled wastewater;
• Mitigate the impact of the SSO;
• Meet the regulatory reporting requiremen ts;
• Evaluate the causes of failure related to certain SSOs; and • Revise response procedures resulting from the debrief and failure analysis of certain SSOs.

6. SSO Detection and Notification
ref. SWRCB Order No. 2006 -0003-DWQ VI(a)

Veolia Water North America – City of Richmond has adopted SSO response procedures that assure rapid response to minimize or eliminate impacts resulting from each SSO. The RMSD manages the sewer collection system through a contract with Veolia Water. Veolia provides SSO assist ance and response during business and non-business hours.

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 7

6.1 PUBLIC OBSERVATION

The City is most often notified of an SSO by Veolia staff . However on occasion, SSOs may be called into a particular City department in which case Veolia staff is contact ed to execute a response. Veolia learns of the SSO through its crews, contractors, or a member of the public. When a member of the public notices an overflow or blockage, they report this occurrence to the Veolia SSO hotline. The hotline is answered by Ve olia staff at the Wastewater Treatment Plant (601 Canal Boulevard, Richmond, CA). The Veolia number for reporting SSOs is (510) 412 -2001. The Veolia hotline is included in the telephone book and on the City’s website, which can be accessed through the lin k:
http://www.ci.richmond.ca.us under the “Wastewater” tab.

Normal Work Hours
Normal business hours are Monday through Friday from 7:00 AM to 4:00 PM. Service calls received during normal business hours are taken immediately by the Veolia Collection Syste m Planner/Scheduler who fills out the Service Call Report form and then dispatches the call to the Veolia Field Crew who respond within 30 minutes to one hour of an SSO event.

After Hours
After normal business hours, service calls are taken by the Veolia Water answering service center , which relays the information to the Veolia Field Crew on -call representative, who responds within a one hour time frame. The Veolia representative completes a standardized form available through the Infonet mobile tablet that records start time of the incident and other information related to the SSO.

When calls are received , either during normal work hours or after hours, the individual receiving the call will collect the following information :
• Time and date of call
• Specific location of potential overflow or incident
• Nature of call
• In case of SSO, estimated start time of overflow and how long it has been occurring • Caller’s name, telephone number , and address
• Caller’s observations (e.g., odor, duration, location on property, known impacts, indication if surface water impacted, appearance at cleanout or manhole) • Other relevant information
The following (Figure 6.1) is an overview of receiving a sewage overflow or backup report (see next page):

6.2 NOTIFICATION FROM PUMP STATION SCADA ALARMS

Any overflows associated with a lift station are detected and reported through the SCADA remote monitoring and MISSION alarm system to Veolia on call sta ff. Pump or equipment failures and high wet well levels produce alarms , which may require a response depending on the circumstances. The on call person would initiate a support response by the field crew as necessary. A lift station overflow may also be relayed by the public to Veolia and addressed as described above.

6.3 CITY STAFF OBSERVATION

City staff conducts periodic inspections of its sewer system facilities as part of their routine activities.

Any problems noted with the sewer system facili ties are reported to appropriate City staff that, in turn, notify Veolia Water staff so they can respond to emergency situations. Work orders are issued to correct non-emergency conditions.

6.4 CONTRACTOR OBSERVATION

The following procedures are to be followed in the event that a contractor causes or witnesses a Sanitary Sewer Overflow. If the contractor causes or witnesses an SSO they will:

1. Immediately notify the City

2. Protect storm drains

3. Protect the public

4. Provide Information to City/Veolia Water Staff such as start time, appearance point (s), suspected cause, weather conditions, etc.

5. Direct ALL media and public relations requests to the City of Richmond Public Information Officer.

Appendix E includes a handout for Contractors with a flowchart of the above procedures.

7.2 First Responder Priorities

The first responder’s priorities are:
• To follow safe work practices.
• To respond promptly with the appropriate and necessary equipment. • To contain the spill wherever feasible.
• To restore the flow as soon as practicable.
• To minimize public access to and/or contact with the spilled sewag e. • To promptly notify the Field Supervisor and Collection System Manager in event of major SSO. • To return the spilled sewage to the sewer system.
• To restore the area to its original condition (or as close as possible). • To photograph and document affected a nd unaffected areas from a spill. • To protect storm drains/waters of the state.

7.3 Safety

The first responder is responsible for following safety procedures at all times. Special safety precautions must be observed when performing sewer work. There may be times when City/Veolia Water personnel responding to a sewer system event are not familiar with potential safety hazards peculiar to sewer work. In such cases it is appropriate to take the time to discuss safety issues, consider the order of work, and check safety equipment before starting the job. This includes use of gas monitoring detectors for air quality in manholes and traffic controls at the site.

7.4 Initial Response

The first responder must respond to the reporting party/problem site and v isually check for potential sewer stoppages or overflows.

The first responder will:
• Note arrival time at the site of the overflow/backup. • Verify the existence of a public sewer system spill or backup. • Determine if the overflow or blockage is from a public or private sewer. • Identify and assess the affected area and extent of spill. • Contact caller if time permits.
• If the spill is large or in a sensitive area, document conditions upon arrival with photographs.

Decide whether to proceed with clearing the bl ockage to restore the flow or to initiate containment measures. The guidance for this decision is:
o Small spills (i.e., spills that are easily contained) – proceed with clearing the blockage. o Moderate or large spill where containment is anticipated to be s imple – proceed with the containment measures.
o Moderate or large spills where containment is anticipated to be difficult – proceed with clearing the blockage; however, whenever deemed necessary, call for additional assistance and implement containment meas ures.
• Take steps to contain the SSO. For detailed procedures refer to Appendix B: Sanitary Sewer Backup Procedures, and Appendix C: Sanitary Sewer Overflow Packet.

7.5 Initiate Spill Containment Measures

The first responder will attempt to contain as m uch of the spilled sewage as possible using the following steps:
• Determine the immediate destination of the overflowing sewage.

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 12 • Plug storm drains using air plugs, sandbags, and/or plastic mats to contain the spill, whenever appropriate. If spilled sewage has made contact with the storm drainage system, attempt to contain the spilled sewage by plugging downstream storm drainage facilities. • Contain/direct the spilled sewage using dike/dam or sandbags. • Pump around the blockage/pipe failure .

For detailed proc edures refer to Appendix C: Sanitary Sewer Overflow Packet.

7.6 Restore Flow

Using the appropriate cleaning equipment, set up downstream of the blockage and hydro -clean upstream from a clear manhole. Attempt to remove the blockage from the system and o bserve the flows to ensure that the blockage does not re occur downstream. If the blockage cannot be cleared within a reasonable time from arrival, or sewer requires construction repairs to restore flow, then initiate containment and/or bypass pumping. If assistance is required, immediately contact other employees, contractors, and equipment suppliers. For detailed procedures refer to Appendix C: Sanitary Sewer Overflow Packet.

7.7 Equipment

Veolia has a variety of equipment available for clearing block ages and impact mitigation and cleanup activities, including the following:

• Three (3) Combination Sewer Cleaning Trucks (vacuum and jetter/hydroflush). Two of these trucks are provided by the City as part of the contract between the City and Veolia. • One (1) Rodder Truck.
• Two (2) CCTV Trucks.
• One (1) Emergency Response Trailer
• Two (2) Traffic Utility Trucks
• One (1) Small Gas Generator
• One (1) 1 ½” Portable Pump
• One (1) 3” Honda Portable Pump

8. Recovery and Cleanup
ref. SWRCB Order No. 2006 -0003-DWQ Element 6(e)

The recovery and cleanup phase begins immediately after the flow has been restored and the spilled sewage has been contained to the extent possible. The SSO recovery and cleanup procedures are:

8.1 Estimate the Volume of Spilled Sewage

Use the methods outlined in the Sanitary Sewer Backup Packet (Appendix B), Sanitary Sewer Overflow Packet (Appendix C), and/or the Field Guide to estimate the volume of the spilled sewage. Wherever possible, document the estimate using photos and/or video of th e SSO site before and during the recovery operation.

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 13

8.2 Recovery of Spilled Sewage

Vacuum up and/or pump the spilled sewage and rinse water, and discharge it back into the sanitary sewer system.

8.3 Clean-up and Disinfection
Clean up and disinfection procedures will be implemented to reduce the potential for human health issues and adverse environmental impacts that are associated with an SSO event. The procedures described are for dry weather conditions and will be modified as required for wet weath er conditions.

Where cleanup is beyond the capabilities of City staff, a cleanup contractor will be used.

Private Property
City crews are responsible for the cleanup when the property damage is minor in nature and is outside of private building dwellings , such as in front, side and backyards, easements, etc . In all other cases, affected property owners can call a water damage restoration contractor to complete the cleanup and restoration. If the overflow into property is caused by a failure in the City-owned wastewater collection infrastructure, Veolia or City of Richmond staff will call out a water damage restoration contractor to complete the cleanup and restoration as soon as they are made aware of the problem. In both cases, City claim forms may be iss ued if requested by the property owners.

Hard Surface Areas
Collect all signs of sewage solids and sewage -related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water and/or deozyme or simil ar non -toxic biodegradable surface disinfectant until the water runs clear. The flushing volume will be approximately three times the estimated volume of the spill. Take reasonable steps to contain and vacuum up the wastewater. Allow area to dry. Repea t the process if additional cleaning is required.

Landscaped and Unimproved Natural Vegetation
Collect all signs of sewage solids and sewage -related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with cl ean water until the water runs clear. The flushing volume will be approximately three times the estimated volume of the spill.

Either contain or vacuum up the wash water so that none is released. Allow the area to dry.

Repeat the process if additional cleaning is required.

Natural Waterways
The Department of Fish and Wildlife will be notified by CalOES for SSOs greater than or equal to 1,000 gallons.

Wet Weather Modifications
Omit flushing and sampling during heavy storm events (i.e., sheet of rainwa ter across paved surfaces) with heavy runoff where flushing is not required and sampling would not provide meaningful results.

8.4 Public Notification

Signs will be posted and barricades put in place to keep vehicles and pedestrians away from contact with spilled sewage. County Environmental Health instructions and directions regarding placement and language of public warnings will be followed when directed . Additionally, the City of Richmond staff will use their best judgment regarding supplemental sig n placement in order to protect the public and local

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 14 environment. Signs will not be removed until directed by County Environmental Health, Collections System Manager , or designee.

Creeks, streams and beaches that have been contaminated as a result of an S SO will be posted at visible access locations until the risk of contamination has subsided to acceptable background bacteria levels. The warning signs, once posted, will be checked at least every day to ensure that they are still in place. Photographs of sign placement will be taken.

In the event that an overflow occurs at night, the location will be inspected first thing the following day.

The field crew will look for any signs of sewage solids and sewage -related material that may warrant additional cleanup activities.

When contact with the local media is deemed necessary, the City of Richmond Public Information Officer will provide the media with all revelvant information.

9. Water Quality
ref. SWRCB Order No. 2006 -0003-DWQ Element 6(f)

9.1 Water Quality Sampling and Testing

Water quality sampling and testing is required for Category 1 SSOs of 50,000 gallons or greater to determine the extent and impact of the SSO. The water quality sampling procedures must be implemented within 48 hours and include the following:
• The City staff will coll ect samples as soon as possible, but no later than 48 hours after the discovery and mitigation of the SSO event.
• Upon notice of a Category 1 SSO, the Monitoring Coordinator will determine where the field crew w ill sample. The Monitoring Coordinator will be responsible for determining the sampling locations. At a minimum, sampling will occur where the SSO enters the surface water body. If it is safe, samples will also be taken 50 - 100 feet upstream of the entry point, and at least one point downstream of the entry point. The downstream location(s) will be determined from visual monitoring and estimated spill travel time. The Monitoring Coordinator will provide a detailed description of potential monitoring site l ocations to the Field Crew. • Upon arrival at the monitoring sites, the Field Crew will determine the best locations to sample by assessing the hydrology of the receiving water and any safety precautions. The Field Crew should look for locations where the r eceiving water can easily be entered or sampled mid - channel by a grab pole. Once the sampling site location is selected, but before sampling starts, the Field Crew will record the latitude and longitude of the sampling location into the Field Form. • The samples shall then be brought to the Caltest Laboratory within eight hours of collection time.

If the Caltest Laboratory is closed an alternate testing laboratory may be used that is certified for the required water quality tests.

9.2 Water Quality Monitori ng Plan

The City Water Quality Monitoring Plan will be implemented immediately upon discovery of any Category 1 SSO of 50,000 gallons or more in order to assess impacts from SSOs to surface waters.

The SSO Water Quality Monitoring Program will:

1. Contain protocols for water quality monitoring.

2. Account for spill travel time in the surface water and scenarios where monitoring may not be possible (e.g. safety, access restrictions, etc.)

3. Require water quality analyses for ammonia and bacterial indicators to be performed by an

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 15 accredited or certified laboratory.

4. Require monitoring instruments and devices used to implement the SSO Water Quality Monitoring Program to be properly maintained and calibrated, including any records to document maintenance and calibratio n, as necessary, to ensure their continued accuracy.

5. Within 48 hours of the City becoming aware of the SSO, require water quality sampling for ammonia and total and fecal coliform .

6. Observe proper chain of custody procedures.

9.3 SSO Technical Report

The City will submit an SSO Technical Report to the CIWQS Online SSO Database within 45 calendar days of the SSO end date for any SSO in which 50,000 gallons or greater are spilled to surface waters.

The City’s Legally Responsible Official (LRO) will supervise the preparation of this report and will certify this report. This report, which does not preclude the Water Boards from requiring more detailed analyses if requested, shall include at a minimum, the following:

Causes and Circumstances of the SSO:
• Complete and detailed explanation of how and when the SSO was discovered. • Diagram showing the SSO failure point, appearance point(s), and final destination(s). • Detailed description of the methodology employed and available data used to calculate the volume of the SSO and, if applicable, the SSO volume recovered. • Detailed description of the cause(s) of the SSO.
• Copies of original field crew records used to document the SSO. • Historical maintenance records for the failure location.

City/Veolia Water Response to SSO:
• Chronological narrative description of all actions taken by the City to terminate the spill. • Explanation of how the SSMP Overflow Emergency Response Plan was implemented to respond to and mitigate the SSO.
• Final corrective action(s) completed and/or pl anned to be completed, including a schedule for actions not yet completed.

Water Quality Monitoring:
• Description of all water quality sampling activities conducted including analytical results and evaluation of the results.
• Detailed location map illustrati ng all water quality sampling points.

10. Sewer Backup Into/Onto Private Property Claims Handling Policy

It is the policy of the City that a claims form shall be offered to anyone wishing to file a claim. The following procedures will be observed for all sewer overflows/backups into/onto private property:

• City staff will offer a City claim form irrespective of fault whenever it is possible that the sanitary sewer backup may have resulted from an apparent blockage in the City-owned sewer lines or whenev er a City customer requests a claim form. The claim may later be rejected if subsequent investigations into the cause of the loss indicate the City was not at fault.

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 16 • It is the responsibility of the Field Crew to gather information regarding the incident and notify the Collection System Supervisor or his/her designee.

• It is the responsibility of the City Risk Manager to review all claims and to oversee the adjustment and administration of the claim to closure.

11. Notification, Reporting, Monitoring and Recordkeeping Requirements ref. SWRCB Order No. 2006 -0003-DWQ Element 6(c)

In accordance with the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (SSS GWDRs), the City of Richmond maintains records for each sanitary sewe r overflow. Records include:
• Documentation of response steps and/or remedial actions • Photographic evidence to document the extent of the SSO, field crew response operations, and site conditions after field crew SSO response operations have been completed . The date, time, location, and direction of photographs taken will be documented.
• Documentation of how any estimations of the volume of discharged and/or recovered volumes were calculated including all assumptions made.

For reporting purposes, if one SSO event of whatever category results in multiple appearance points in a sewer system, a single SSO report is required in CIWQS that includes the GPS coordinates for th e location of the SSO appearance point closest to the failure point, blockage or location of the flow condition that cause the SSO, and descriptions of the locations of all other discharge points associated with the single SSO event.

11.2 Complaint Recor ds

The City/Veolia Water maintains records of all complaints received whether or not they result in sanitary sewer overflows. These complaint records include:
• Date, time, and method of notification
• Date and time the complainant or informant first noticed the SSO or occurrence related to the call • Narrative description describing the complaint
• A statement from the complainant or informant, if they know, of whether or not the potential SSO may have reached waters of the state
• Name, address, and contact telep hone number of the complainant or informant reporting the potential SSO (if not reported anonymously)
• Follow-up return contact information for each complaint received (if not reported anonymously) • Final resolution of the complaint with the original complai nant • Work service request information used to document all feasible and remedial actions taken All complaint records will be maintained for a minimum of five years whether or not they result in an SSO. SSO records are maintained in the Computerized Main tenance Management System (CMMS) .

12. Post SSO Event Debriefing
ref. SWRCB Order No. 2006 -0003-DWQ Element 6(d)

Every SSO event is an opportunity to evaluate the City/Veolia Water response and reporting procedures. Each overflow event is unique, with its own elements and challenges including volume, cause, location, terrain, climate, and other parameters.

As soon as possible after Category 1 and Category 2 SSO events, the Collection System Manager, and all of the participants, from the person who r eceived the call to the last person to leave the site, will meet to review the procedures used and to discuss what worked and where improvements could be made in preventing or responding to and mitigating future SSO events. The results of the debriefing wi ll be documented and tracked to ensure the action items are completed as scheduled.

13. Failure Analysis Investigation
ref. SWRCB Order No. 2006 -0003-DWQ Element 6(d)

The objective of the failure analysis investigation is to determine the “root cau se” of the SSO and to identify corrective action(s) needed that will reduce or eliminate future potential for the SSO to recur or for other SSOs to occur.

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 19 The investigation will include reviewing all relevant data to determine appropriate corrective acti on(s) for the line segment. The investigation will include:
• Reviewing and completing the Sanitary Service Report Form and any other documents related to the incident
• Reviewing the incident timeline and other docum entation regarding the incident • Reviewing communications with the reporting party and witness • Reviewing volume estimate, volume recovered estimate, volume estimation assumptions and associated drawings
• Reviewing available photographs
• Interviewing staff that responded to the spill
• Reviewing past maintenance records
• Reviewing past CCTV records,
• Conducting a CCTV inspection to determine the condition of all line segments immediately following the SSO and reviewing the video and logs,
• Reviewing any Fats, Oils, Roots and Grease ( FROG) related information or results • Post SSO debrief records
• Interviews with the public at the SSO location

The product of the failure analysis investigation will be the determination of the root cause and the identification and scheduling of the corrective actions. The Colle ction System Failure Analysis Form will be used to document the investigation.

14. SSO Response Training
ref. SWRCB Order No. 2006 -0003-DWQ Element 6(d)

This section provides information on the training that is required to support this Overflow Eme rgency Response Plan.

14.1 Initial and Annual Refresher Training

All City /Veolia Water personnel who may have a role in responding to, reporting, and/or mitigating a sewer system overflow will receive training on the contents of this OERP. All new emplo yees will receive training before they are placed in a position where they may have to respond. Current employees will receive annual refresher training on this plan and the procedures to be followed. The City/Veolia Water will document all training.

Affected employees will receive annual training on the following topics by knowledgeable trainers:
• The City/Veolia Water Overflow Emergency Response Plan and Sanitary Sewer Management Plan
• Sanitary Sewer Overflow Volume Estimation Techniques • Researching and documenting Sanitary Sewer Overflow Start Times • Impacted Surface Waters: Response Procedures
• State Water Resources Control Board Employee Knowledge Expectations • Employee Core Competency Evaluations on Sanitary Sewer Operations • Water Quality Sampling Plan

The City/Veolia Water will verify that annual safety training requirements are current for each employee,

© 2004-2017 DKF Solutions Group, LLC. All rights reserved. OERP Page 20 and that employees are competent in the performance of all core competencies. This will be verified through electronic testing, interviews and observ ations. The City/Veolia Water will address, through additional training/instruction, any identified gaps in required core competencies.

Through SWRCB Employee Knowledge Expectations training the employee will be able to answer the following:

1. Please briefly describe your name and job title.

2. Please describe for us approximately when you started in this field and how long you have worked for your agency.

3. Please expand on your current position duties and role in responding in the field to any SSO complaints.

4. Please describe your SOPs used to respond/mitigate SSOs when they occur.

5. Describe any training your agency provides or sends you to for conducting spill volume estimates.

6. We are interested in learning more about how your historical SSO response activit ies have worked in the field. We understand from discussions with management earlier that you use the OERP from the SSMP. Please elaborate on how you implement and utilize the procedures in the plan.

7. Historically, before any recent changes, can you plea se walk us through how you would typically receive and respond to any SSO complaints in the field?

8. Can you tell us who is responsible for estimating SSO volumes discharged? If it is you, please describe how you go about estimating the SSO volume that you record on the work order/service request forms?

9. What other information do you collect or record other than what is written on the work order form?

10. Describe if and when you ever talk with people that call in SSOs (either onsite or via telephone) to further check out when the SSO might have occurred based on what they or others know? If you do this, can you tell us where this information is recorded?

11. We understand you may be instructed to take pictures of some sewer spills/backups into structures. Other than these SSOs, when else would you typically take any pictures of an SSO?

12. Please walk us through anything else you’d like to add to help us better understand how your field crews respond and mitigate SSO complaints.

14.2 SSO Response Drills

Periodic training drills or field exercises will be held to ensure that employees are up to date on these procedures, equipment is in working order, and the required materials are readily available. The training drills will cover scenarios typically observed duri ng sewer related emergencies (e.g. mainline blockage, mainline failure, and lateral blockage). The results and the observations during the drills will be recorded and action items will be tracked to ensure completion.

14.3 SSO Training Record Keeping

Records will be kept of all training that is provided in support of this plan. The records for all scheduled training courses and for each overflow emergency response training event and will include date, time, place, content, name of trainer(s), and name s and titles of attendees.

Veolia Water – City of Richmond: Overflow Emergency Response Plan B-2 Sanitary Sewer Backup Response Packet
Bubbled Toilets Letter

Dear City of Richmond Customer,

Thank you for informing us that your toilet bubbled while our crews were working in proximity of your property.

We apologize for the inconvenience and hope that this letter will answer some of your questions about bubbling toilets.

1. Is this a health risk?
The water that came out of your toilet is potable water from the toilet bowl. Unless your toilet was in use when this occurred, this water is no different than that encountered while cleaning your toilet.

2. What is the City doing in the street?
In order to insure reliable sewer service, the City inspects, cleans, and repairs its sewer system on a continuous basis.

3. How does sewer cleaning cause my toilet to bubb le?
Typical industry cleaning equipment uses high -pressure water to clean sewers. The first step is to use the high-pressure water jets to propel the hose and cleaning nozzle upstream as far as 800 feet. During this process, air within the main pipe is d isplaced and sometimes goes up the private lateral pipe and releases though the toilet. This can also happen during the cleaning phase, when high -pressure water is pulled downstream to the cleaning truck.

4. What causes the air to come from my toilet?
Over the years, City crews have found that the bubbling of toilets have many causes, some of which are:
• Obstructed vent pipes;
• Vent pipes that are positioned too far from the toilet; • Lateral pipes that may be in use as the crew is cleaning (e.g. draining washing machine, draining bathtub, etc.);
• Lateral pipes that may have obstructions that are causing them to hold water (e.g. roots, grease, etc.).

5. What does City staff do, once informed of a bubbling toilet? City staff will authorize cleanup by an approved remediation contractor and also notify the homeowner that they will be required to install a Backflow Prevention Device.

6. What can I do to prevent my toilet from bubbling?
When a sewer begins to drain slowly, it may be a sign that it needs to be cleaned or rep aired. Trees and shrubs may have root structures that are entering the lateral pipe. The homeowner needs to make sure to have a clean -out for accessing the line. It is the homeowner’s responsibility to keep the sewer lateral pipe in good working conditio n.

It is always a good idea to keep the toilet lid down when not in use, and not install carpets in the bathroom unless they can be easily removed and cleaned. For more information please call the Collections System Manager (510) 426-0008.

Sincerely,

City of Richmond

STEP 2: Draw/sketch the outline (footprint) of the SSO. Then break the footprint down into recognizable shapes. Refer to the example on Page 3.

STEP 3: Calculate the area of the footprint by completing the table below for each shape in Step 2.

If two shapes overlap, select one of the two shapes and estimate the percentage of that shape that does not overlap. Enter that percentage in the % Not Overlapping column. This will ensure that the overlap area is only counted once. Refer to the example on Page 3.

Rectangles Length X Width X % Not Overlapping* = Area

Volume Estimation: Area Volume Estimation Method
STEP 4: Calculate the volume of the SSO that was NOT absorbed into the ground. If the entire SSO was absorbed, skip to Step 5.
a. If SSO is of varying depths, take several measurements at different depths and find the average.
inches ÷ = inches ÷ 12 = feet sum of measurements # of measurements average depth in inches average depth in feet of ponded sewage
b. Calculate SSO volume of ponded sewage in cubic feet by multiplying the Total SSO Area in Step 3 by the average depth calculated in Step 4a. Convert from cubic feet to gallons by multiplying by 7.48.
ft2 x ft = ft3 x 7.48 gal = gallons
SSO area (Step 3) average depth (Step 4a) SSO volume in estimated volume of cubic feet ponded sewage
STEP 5: Calculate the volume of the SSO that was absorbed into the ground. If only a wet stain is observed, use the guidelines on B -6c Page 3 for the average depth . When estimating the volume that was absorbed, take into consideration:
• How long the sewage has been sitting
• The air temperature on the day of the SSO
• Soil type for the area (e.g., hard -packed clay vs. loose or gravely soil) When estimating the volume of the SSO that was absorbed into the ground, it is also advisable to dig down far enough to reach dry soil and take the depth of the wet soil into consideration.

Estimated volume that was absorbed into the soil: gallons Explain how this estimation was determined:

STEP 6: Add the volume not absorbed (Step 4) plus the volume absorbed (Step 5) to get the total estimated volume:

Measure actual depth of standing sewage whenever possible. When depth varies, measure several representative sample points and determine the average. Add the depth of the sample points and then divide that total by the number of sample points.

If the depth is not measurable because it is only a wet stain, consider using the following estimated d epths:
• Depth of a wet stain on concrete surface: 0.0026’ (1/32”) • Depth of a wet stain on asphalt surface: 0.0013’ (1/64”)

How a Sewer System Works
A property owner's sewer pipes are called
service laterals and are connected to larger
local main and regional trunk lines.

Service laterals run from the connection at the
home to the connection with the public sewer.

These laterals are the responsibility of the
property owner and must be maintained by the
property owner. Is my home required to have a
backflow prevention device?
Section 710.1 of the Uniform Plumbing Code
(U.P.C.) states: “Drainage piping serving fixtures
which have flood level rims located below the
elevation of the next upstream manhole cover or
private sewer serving such drainage piping shall
be protected from backflow of sewage by
installing an approved type of backwater valve.”
The intent of Section 710.1 is to protect the
building interior from mainline sewer overflows
or surcharges.

Additionally, U.P.C. 710.6 states: “Backwater
valves shall be located where they will be
accessible for inspection and repair at all times
and, unless continuously exposed, shall be
enclosed in a masonry pit fitted with an
adequately sized removable cover.”

Sewer Spill
Reference Guide

How do sewage spills happen?
Sewage spills occur when the wastewater in underground
pipes overflows through a manhole, cleanout, or broken pipe. Most spills are relatively small and can be stopped and cleaned up quickly, but left unattended they can cause health hazards, damage to homes and businesses, and
threaten the environment, local waterways, and beaches.

Common causes of sewage spills
• Grease build -up
• Tr ee roots
• Broken/cracked pipes
• Missing or broken cleanout caps
• Undersized sewers
• Groundwater/rainwater entering the sewer system
through pipe defects and illegal connections
Prevent most sewage backups with a Backflow
Prevention Device
This type of device can help prevent sewage backups into homes and businesses. If you don’t already have a
Backflow Prevention Device, contact a professional
plumber or contractor to install one as soon as possible.

Protect the environment!
If you let sewage from your property discharge to a gutter or storm drain, you may be subject to penalties and/or out - of-pocket costs for clean -up and enforcement efforts. A property owner may be charged for costs incurred by
agencies responding to spills from private properties.

What to look for:

Sewage spills can be a very noticeable gushing of water from a manhole or a slow water leak that may take time to be noticed. Don’t dismiss unaccounted -for wet areas. Look for:
• Drain backups inside the building.
• Wet ground and/or water leaking around manhole lids
onto your street.
• Leaking water from cleanouts or outside drains
• Unusual odorous wet areas: sidewalks, external walls, ground/landscape around a building.

The followin g are indicators of a possible obstruction in your sewer line:
• Water comes up in floor drains, showers or toilets.
• Toilets, showers or floor drains below ground level drain very slowly.

What to do if there is a spill:

Immediately notify Veolia Water – City of Richmond . Our crews locate the blockage and determi ne if it is in the public sewer. I f it is , the crew removes the blockage and arranges for cleanup.

If the backup is in your private internal plumbing or in the private service laterals, you are required to immediately :
• Control and minimize the spill by shutting off or not using the water
• Keep sewage out of the storm drain system using
sandbags, dirt and/or plastic sheeting
• Call a plumbing professional to clear blockages and make repairs as needed. Look in the yellow pages under
“Plumbing Drain & Sewer Cleaning” or “ Plumbing
Contractors.”
• Always notify your sewer/public works department or
public sewer district of sewage spills.

Spill cleanup inside the home:

For large clean ups, a professional cleaning firm should be contacted to clean up impacted areas, You can locate local firms by looking in the Yellow Pages under “Water Damage” or “Fire Damage.” If you hire a contractor, it is
recommended to get estimates from more than one
company. Sometimes, homeowner’s insurance will pay for
the necessary cleaning due to sewer backups. Not all
policies have this coverage, so check with your agent.

If you decide to clean u p a small spill inside your home, protect yourself from contamination by observing the
following safety measures. Those persons whose
resistance to infection is compromised should not attempt this type of clean up.

Other Tips:
• Keep children and pets out of the affected area until cleanup has been completed.
• Turn off heating/air conditioning systems
• Wear rubber boots, rubber gloves, and goggles during
cleanup of the affected area.
• Discard items that cannot be washed and disinfected
(such as: mattresses, rugs, cosmetics, baby toys, etc.) • Remove and discard drywall and insulation that has
been contaminated with sewage or flood waters.
• Thoroughly clean all hard surfaces (such as flooring, concrete, molding, wood and metal furniture,
countertops, appliances, sinks and other plumbing
fixtures) with hot water and laundry or dish detergent. • He
lp the drying process with fans, air conditioning units, and dehumidifiers.
• After completing cleanup, wash your hands with soap
and water. Use water that has b een boiled for 1 minute (allow the water to cool before washing your hands) OR
us
e water that has been disinfected (solution of 1/8
teaspoon of household bleach per 1 gallon of water). Let it stand for 30 min. If water is cloudy, use ¼ teaspoon of ho
useho ld bleach per 1 gallon of water.
• Wash clothes worn during cleanup in hot water and
detergent (wash apart from uncontaminated clothes).
• Wash clothes contaminated with sewage in hot water
and detergent. Consider using a Laundromat until your
onsite wastewate r system has been professionally
inspected and serviced.
• Seek immediate attention if you become injured or ill.

Spill cleanup outside the home:
• Keep children and pets out of the affected area until cleanup has been completed.
• Wear rubber boots, rubber gloves, and goggles during cleanup of affected area.
• Cl
ean up sewage solids (fecal material) and place in
properly functioning toilet or double bag and place in
garbage container.
• On
hard surfaces areas such as asphalt or concrete, it is
safe to use a 2% b leach solutions, or ½ cup of bleach to 5 gallons of water, but don’t allow it to reach a storm drain as the bleach can harm the environment.
• After cleanup, wash hands with soap and water. Use
water that has been boiled for 1 minute (allow to cool
before w ashing your hands) OR use water that has been
disinfected (solution of 1/8 teaspoon of household
bleach per 1 gallon of water). Let it stand for 30 min. If wa
ter is cloudy, use ¼ teaspoon of household bleach per
1 gallon of water.
• Wash clothes worn during cleanup in hot water and
detergent (wash apart from uncontaminated clothes).
• Wash clothes contaminated with sewage in hot water
and detergent. Consider using a Laundromat until your
onsite wastewater system has been professionally
inspected and serviced.
• Seek immediate attention if you become injured/ill.

CAUTION!
When trying to locate a sewer problem,
never open manholes or other public
sewer structures. Only our crews are
allowed to open & inspect these structures.

sanitary sewer service to your property.

We discovered a blockage in:
o The sanitary sewer main and cleared the line
o The City-maintained portion of your sanitary
sewer lateral and cleared the line.
o Your portion of the sanitary sewer lateral,
which is your responsibility to maintain. We
also found the City’s portion of the lateral and
the main to be flowing normally.

If you require assistance to clear your portion of the
lateral you can look in the Yellow Pages of your
telephone book under “Sewer Contractors” or
“Plumbing Drains & Sewer Cleaning”. If you plan
to hire a contractor we recommend getting
estimates from more than one company.

signs in immediate areas. Be sure to photograph any areas where warnings/barricades are posted, as appropriate.

MEDIA AND PUBLIC RELATIONS GUIDELINES:

Exercise caution in contacts with the public or media when you respond to a spill. Any information you provide or statements you make may become pertinent in the event of possible court action, it is important to AVOID THE FOLLOWING :
§  Giving out the wrong information including providing incorrect facts about a company or other agency § Making accusations against customers, businesses or other agencies § Speculating about the situation you are responding to Be courteous and attempt to provide accurate information to questions within the limits above. In some cases, it may be appropriate to say that we do not have any information, or to delay answering a question and then to say when an answer might be available.

In most cases, refer media requests to the media coordinator indicated on the front of the Sewer Overflow Packet envelope.

NO
YES
If it is a Category 1 spill
greater than or equal to
1,000 gallons, call CalOES
at (800) 852-7550
to make 2-hour notification
and obtain control number.

BEGIN DIVERSION AND CONTAINMENT

1. DIVERT AWAY FROM SENSITIVE AREAS:
a. Cover unplugged storm drains w/mats, or use dirt/other material to divert sewage away from sensitive areas (e.g., schools, playgrounds, intersections, etc.) b. ENSURE PUBLIC CONT ACT DOES NOT OCCUR. Use cones/barricades to isolate area.

2. CONTAIN SPILL & RETURN TO SYSTEM, IF POSSIBLE:
a.  Plug storm drain catch basins or use rubber mats to cover basin inlet and divert flow to catch basin
b.  Build/excavate a berm to channel flow to downstream sanitary sewer manhole (barricade manhole if left open)
c.  Use bypass pumps to pump around blockage until it can be removed d.  Divert to low area of ground where it can be collected later

3. PHOT OGRAPH HOW THE SSO WAS DIVERTED/CONTAINED, AS APPROPRIATE

PRIVATE PROPERTY SSO

1.  Photograph & document all evidence that this SSO is from private property.

2. If customer is not home, complete Customer Service
door hanger. If they are home, provide them with the
pamphlet – “Sewer Spill Reference Guide.”

3.  If tenant or property owner is unable to unwilling to address the cause of the overflow, immediately
contact your supervisor and discuss whether City
Code Enforcement, the County Department of
Environmental Health or Regional Water Quality
Control Board should be notified.

End. Do not continue to Side B

CLEAR BLOCKAGE/STOPPAGE
Use cleaning equipment appropriate to situation to
hydroflush, rodder, or hand rod to clear blockage.

Make certain to either have the vactor setup at
downstream manhole or use a fork/trap at the
manhole outlet to catch any debris released. If
using the rodder, first set-up dry manhole & run
upstream to blockage. Once blockage is broken,
pull out rods & cleaning tools. Leaving rods in
the line could restrict flow. Once flow is normal, run
line to next manhole.

Volume Estimation: Area Volume Estimation Method
STEP 4: Calculate the volume of the SSO that was NOT absorbed into the ground. If the entire SSO was absorbed, skip to Step 5.
a. If SSO is of varying depths, take several measurements at different depths and find the average. inches ÷ = inches ÷ 12 = feet sum of measurements # of measurements average depth in inches average depth in feet of ponded sewage
b. Calculate SSO volume of ponded sewage in cubic feet by multiplying the Total SSO Area in Step 3 by the average depth calculated in Step 4a. Convert from cubic feet to gallons by multiplying by 7.48.
ft2 x ft = ft3 x 7.48 gal = gallons
SSO area (Step 3) average depth (Step 4a) SSO volume in estimated volume of cubic feet ponded sewage
STEP 5: Calculate the volume of the SSO that was absorbed into the ground. If only a wet stain is observed, use the guidelines on C-3c Page 3 for the average depth . When estimating the volume that was absorbed, take into consideration:
• How long the sewage has been sitting
• The air temperature on the day of the SSO
• Soil type for the area (e.g., hard -packed clay vs. loose or gravely soil) When estimating the volume of the SSO that was absorbed into the ground, it is also advisable to dig down far enough to reach dry soil and take the depth of the wet so il into consideration.

Estimated volume that was absorbed into the soil: gallons Explain how this estimation was determined:

STEP 6: Add the volume not absorbed (Step 4) plus the volume absorbed (Step 5) to get the total estimated volume:

How a Sewer System Works
A property owner's sewer pipes are called
service laterals and are connected to larger
local main and regional trunk lines.

Service laterals run from the connection at the
home to the connection with the public sewer.

These laterals are the responsibility of the
property owner and must be maintained by the
property owner. Is my home required to have a
backflow prevention device?
Section 710.1 of the Uniform Plumbing Code
(U.P.C.) states: “Drainage piping serving fixtures
which have flood level rims located below the
elevation of the next upstream manhole cover or
private sewer serving such drainage piping shall
be protected from backflow of sewage by
installing an approved type of backwater valve.”
The intent of Section 710.1 is to protect the
building interior from mainline sewer overflows
or surcharges.

Additionally, U.P.C. 710.6 states: “Backwater
valves shall be located where they will be
accessible for inspection and repair at all times
and, unless continuously exposed, shall be
enclosed in a masonry pit fitted with an
adequately sized removable cover.”

Sewer Spill
Reference Guide

How do sewage spills happen?
Sewage spills occur when the wastewater in underground
pipes overflows through a manhole, cleanout, or broken pipe. Most spills are relatively small and can be stopped and cleaned up quickly, but left unattended they can cause health hazards, damage to homes and businesses, and
threaten the environment, local waterways, and beaches.

Common causes of sewage spills
• Grease build -up
• Tr ee roots
• Broken/cracked pipes
• Missing or broken cleanout caps
• Undersized sewers
• Groundwater/rainwater entering the sewer system
through pipe defects and illegal connections
Prevent most sewage backups with a Backflow
Prevention Device
This type of device can help prevent sewage backups into homes and businesses. If you don’t already have a
Backflow Prevention Device, contact a professional
plumber or contractor to install one as soon as possible.

Protect the environment!
If you let sewage from your property discharge to a gutter or storm drain, you may be subject to penalties and/or out - of-pocket costs for clean -up and enforcement efforts. A property owner may be charged for costs incurred by
agencies responding to spills from private properties.

What to look for:

Sewage spills can be a very noticeable gushing of water from a manhole or a slow water leak that may take time to be noticed. Don’t dismiss unaccounted -for wet areas. Look for:
• Drain backups inside the building.
• Wet ground and/or water leaking around manhole lids
onto your street.
• Leaking water from cleanouts or outside drains
• Unusual odorous wet areas: sidewalks, external walls, ground/landscape around a building.

The followin g are indicators of a possible obstruction in your sewer line:
• Water comes up in floor drains, showers or toilets.
• Toilets, showers or floor drains below ground level drain very slowly.

What to do if there is a spill:

Immediately notify Veolia Water – City of Richmond . Our crews locate the blockage and determi ne if it is in the public sewer. I f it is , the crew removes the blockage and arranges for cleanup.

If the backup is in your private internal plumbing or in the private service laterals, you are required to immediately :
• Control and minimize the spill by shutting off or not using the water
• Keep sewage out of the storm drain system using
sandbags, dirt and/or plastic sheeting
• Call a plumbing professional to clear blockages and make repairs as needed. Look in the yellow pages under
“Plumbing Drain & Sewer Cleaning” or “ Plumbing
Contractors.”
• Always notify your sewer/public works department or
public sewer district of sewage spills.

Spill cleanup inside the home:

For large clean ups, a professional cleaning firm should be contacted to clean up impacted areas, You can locate local firms by looking in the Yellow Pages under “Water Damage” or “Fire Damage.” If you hire a contractor, it is
recommended to get estimates from more than one
company. Sometimes, homeowner’s insurance will pay for
the necessary cleaning due to sewer backups. Not all
policies have this coverage, so check with your agent.

If you decide to clean u p a small spill inside your home, protect yourself from contamination by observing the
following safety measures. Those persons whose
resistance to infection is compromised should not attempt this type of clean up.

Other Tips:
• Keep children and pets out of the affected area until cleanup has been completed.
• Turn off heating/air conditioning systems
• Wear rubber boots, rubber gloves, and goggles during
cleanup of the affected area.
• Discard items that cannot be washed and disinfected
(such as: mattresses, rugs, cosmetics, baby toys, etc.) • Remove and discard drywall and insulation that has
been contaminated with sewage or flood waters.
• Thoroughly clean all hard surfaces (such as flooring, concrete, molding, wood and metal furniture,
countertops, appliances, sinks and other plumbin g
fixtures) with hot water and laundry or dish detergent. • He
lp the drying process with fans, air conditioning units, and dehumidifiers.
• After completing cleanup, wash your hands with soap
and water. Use water that has b een boiled for 1 minute (allow the water to cool before washing your hands) OR
us
e water that has been disinfected (solution of 1/8
teaspoon of household bleach per 1 gallon of water). Let it stand for 30 min. If water is cloudy, use ¼ teaspoon of ho
useho ld bleach per 1 gallon of water.
• Wash clothes worn during cleanup in hot water and
detergent (wash apart from uncontaminated clothes).
• Wash clothes contaminated with sewage in hot water
and detergent. Consider using a Laundromat until your
onsite wastewate r system has been professionally
inspected and serviced.
• Seek immediate attention if you become injured or ill.

Spill cleanup outside the home:
• Keep children and pets out of the affected area until cleanup has been completed.
• Wear rubber boots, rubber gloves, and goggles during cleanup of affected area.
• Cl
ean up sewage solids (fecal material) and place in
properly functioning toilet or double bag and place in
garbage container.
• On
hard surfaces areas such as asphalt or concrete, it is
safe to use a 2% b leach solutions, or ½ cup of bleach to 5 gallons of water, but don’t allow it to reach a storm drain as the bleach can harm the environment.
• After cleanup, wash hands with soap and water. Use
water that has been boiled for 1 minute (allow to cool
before w ashing your hands) OR use water that has been
disinfected (solution of 1/8 teaspoon of household
bleach per 1 gallon of water). Let it stand for 30 min. If wa
ter is cloudy, use ¼ teaspoon of household bleach per
1 gallon of water.
• Wash clothes worn during cleanup in hot water and
detergent (wash apart from uncontaminated clothes).
• Wash clothes contaminated with sewage in hot water
and detergent. Consider using a Laundromat until your
onsite wastewater system has been professionally
inspected and serviced.
• Seek immediate attention if you become injured/ill.

CAUTION!
When trying to locate a sewer problem,
never open manholes or other public
sewer structures. Only our crews are
allowed to open & inspect these structures.

A PROJECT MANAGEMENT
A.1 PROJECT ORGANIZATION
This monitoring program will be conducted under the direction of the Richmond Municipal Sewer District (RMSD) with guidance provided by Larry Walker Associates (LWA). Caltest Analytical Laboratory of Napa (Caltest) will serve as the primary laboratory, but alternatives might be used due to logistics and timing. The Project Contact list is provided in Table 1.

A.2 BACKGROUND
In 2006, the State Water Resources Control Board (State Water Board) adopted Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (SSS WDRs), Order No. 2006 -0003-DWQ. The Monitoring and Reporting Program (MRP) established monitoring, record keeping, reporting, and public notification requirements.

On September 9, 2013, Order No. WQ 2013-0058-EXEC became effective that clarified and expanded requirements of the original MRP and defined new sanitary sewer overflow (SSO) categories. The SSO definitions, as well as the notification, monitoring, and technical reporting requirements are shown in Figure 1.

This monitoring plan addresses water quality monitoring requirements for Category 1 SSOs that are greater than or equal to 50,000 gallons. As defined by Order No. WQ 2013-0058-EXEC, the following elements must be included in an SSO Water Quality Monitoring Plan to comply with subsection D.7(v) of the SSS WDRs:

1. Protocols for water quality monitoring.

2. Account for spill travel time in the surface water and scenarios where monitoring may not be possible (e.g. safety, access restrictions, etc.).

3. Water quality monitoring analyses for ammonia and bacterial indicators to be performed by an accredited or certified laboratory.

4. Procedures for proper maintenance and calibration of monitoring instruments and devices used to implement the SSO Water Quality Monitoring Program and documentation of maintenance and calibration, as necessary, to ensure their continued accuracy.

5. Water quality sampling within 48 hours of the RMSD becoming aware of the SSO, for, at a minimum, the following constituents:
a. Ammonia
b. Total Coliform

B DATA GENERATION AND ACQUISITION
B.1 SAMPLING PROCESS DESIGN
B.1.1 Sampling Event Timing
The Monitoring Coordinator will determine when the field crew will be mobilized to sample the receiving water.

Sampling must be conducted within 48 hours after initial Category 1 SSO and spill volume notification. The monitoring coordinator will target daylight sampling within the first 24 hours of the SSO notification, but sample timing may be shifted due to safety and logistical issues.

Sampling will not be conducted if there are any concerns regarding field crew safety. These concerns may include heavy rain events, which compromise access points through flooding and swift currents. Thunderstorms will also be avoided when lightning is occurring. Sampling will only be conducted if there are at least two members of the field crew team available.

B.1.2 Monitoring Site Locations
Upon notice of a Category 1 SSO, the Monitoring Coordinator will determine where the field crew will sample. The Monitoring Coordinator will be responsible for determining the sampling locations. At a minimum, sampling will occur where the SSO enters the surface water body. If it is safe, samples will also be taken 50 - 100 feet upstream of the entry point, and at least one point downstream of the entry point. The downstream location(s) will be determined from visual monitoring and estimated spill travel time (see Section B.3.1). The Monitoring Coordinator will provide a detailed description of potential monitoring site locations to the Field Crew.

Upon arrival at the monitoring sites, the Field Crew will determine the best locations to sample by assessing the hydrology of the receiving water and any safety precautions. The Field Crew should look for locations where the receiving water can easily be entered or sampled mid-channel by a grab pole. Once the sampling site location is selected, but before sampling starts, the Field Crew will record the latitude and longitude of the sampling location into the Field Form (APPENDIX A).

B.2 EQUIPMENT PREPARATION
The Field Crew shall maintain a sampling kit with the necessary supplies to conduct a monitoring event. Table 2 lists the equipment and supplies that will be included in the sampling kit.

B.2.2 Field Meter Calibration
All field meters will be properly calibrated and maintained by the Field Crew. Calibrations will be performed according to the methods and frequency recommended by the equipment manufacturer. When calibrating the instruments, the Field Crew will document all pertinent information in a Calibration Log (APPENDIX B) and keep it with the rest of the project documentation.

B.3 WATER QUALITY MONITORING
The Field Crew will be responsible for the following tasks upon arrival at the monitoring location:

1. Determine best sampling locations and record latitude and longitude readings for the upstream, SSO entry point, and downstream sampling sites.

2. Calculate spill travel time at the downstream monitoring site (if possible)

3. Collect water quality samples in the following order: first at the SSO entry point, second at the downstream site(s) – if possible, and third at the upstream monitoring site(s) - if possible

4. Complete all field forms and prepare the samples for delivery to the laboratory.

The following sections outline the necessary steps the Field Crew must take when performing the above actions.

B.3.1 Spill Travel Time
When the Field Crew arrives at the downstream monitoring site, they will try to estimate spill travel time by calculating travel time within enclosed storm drains (distance traveled ∕initial spill rate) and within open surface waters. Travel time within the open surface waters can be determined two different ways depending on the accessibility and safety of the monitoring site.

Richmond Municipal Sewer District
SSO Monitoring Plan 5 March 2017
Copyright 2013-2017 © City of Richmond – All rights reserved.

B.3.1.1 Velocity Probe
Using a velocity probe is the preferred method of spill travel time calculation, but it requires extra safety precautions, since the Field Crew will have to wade and cross the surface water body.” Since the receiving water bodies for the areas around the RMSD are unsafe to enter, the RMSD has determined that it will not be the method used for determining spill travel time.

B.3.1.2 Visual Velocity Estimation
If the receiving water body is unsafe to enter, the velocity can be measured by observing floating debris.

1. The Field Crew members will stand on the edge of the channel, 30 feet apart.

2. The Field Crew member standing upstream will indicate when a large piece of debris passes their point. At this time the Field Crew member standing downstream will start timing.

3. Once the same piece of debris passes the downstream Field Crew member, they will stop timing and calculating the velocity (ft/sec) by dividing 30 feet by the number of seconds it took for the debris to travel that length.

If there isn’t any large debris floating in the surface water, the upstream Field Crew member can use a nearby stick or other buoyant object (field crew is not to add “debris” or any other material that could be considered “trash” to waters to check velocity, unless the object can be easily retrieved).

B.3.2 Sample Collection Methods
Sample collection methods will vary depending on the surface water and the safety of the Field Crew. Clean, powder-free, nitrile gloves will be worn for all bottle handling. The direct fill sample collection method is the preferred sampling method, since it does not use an intermediate container. In cases where the direct fill method cannot be used due to accessibility or safety an intermediate bottle and a grab pole can be used.

B.3.2.1 Direct Fill Sample Collection (this process has been determined unsafe and is NOT to be used by City Staff).

The direct fill sample collection method will be used in cases where the surface water can be entered safely by the Field Crew. Field Crew will wear waders and ensure that the water level and velocity of the surface water are low enough to provide a safe entry and sampling environment.

Ammonia and bacteriological sample bottles will be filled by direct submersion to approximately mid-depth as follows.

1. Wade to approximately the area of the water body with the highest flow rate and face upstream. This will most likely be midstream, but can be in a different portion of the stream, depending on the hydrology.

2. Submerge the sample bottle with its cap on to approximately mid-depth at a location of significant flow (avoid stagnant water). Hold the bottle upright under the surface while it is still capped.

3. Open the lid carefully just a little to let water run in. Fill the bottle and screw the cap tightly while the bottle is still underneath the surface.

4. Remove bottle from stream and place on ice.

Richmond Municipal Sewer District
SSO Monitoring Plan 6 March 2017
Copyright 2013-2017 © City of Richmond – All rights reserved.

B.3.2.2 Intermediate Container Sample Collection (method to be used most often) If the flow, water level and/or access point are deemed unsafe then an intermediate bottle attached to a grab pole will be used for sample collection. A clean, new intermediate bottle will be used for each sampling event and sampling site.

Ammonia and bacteriological sample bottles will be filled by intermediate container sample collection as follows:

1. Attach the new, clean intermediate bottle to a subsurface sampling pole.

2. Submerge the intermediate bottle, attached to expandable pole, to approximately mid -depth at a location of significant flow (avoid stagnant water).

3. Pull the release lever on the sample pole. You should see bubbling below the surface. This indicates the bottle is filling.

4. Remove bottle from water, pull the lever and empty contents. Repeat this twice more.

5. Once the intermediate bottle is properly rinsed, submerge the intermediate bottle, attached to expandable pole, to approximately mid-depth at a location of significant flow (avoid stagnant water).

6. Pull the release lever on the subsurface sampling pole. You should see bubbling below the surface. This indicates the bottle is filling.

7. Carefully remove the pole (with the bottle attached) from the water.

8. Unscrew the bottle from the subsurface sampling pole, being careful not to spill the contents.

9. Using the sample bottle (that was attached to the pole), fill the bacteriological sample container s and then the ammonia bottle. Ensure that none of the bottles overflow and that the preservative stays in the sample container.

10. After the bottles have been filled, replace bottle lids, label each bottle with sample label information, remove bottle and place in cooler on ice.

Program
Introduction
Fats, Oils, and grease, abbreviated as FOG, are an issue due their ability to cause sanitary sewer blockages that may result in discharges of untreated wastewater on Food Handling Facilities (FHF’s) and to storm drains, creeks and the San Francisco Bay. FOG discharges result from improper management of food waste in residences and commercial FHF’s.

Background
The City of Richmond FOG source control program was initiated in 2003. A field survey identified all food service facilities with and without grease control devices. Periodic inspection of food service facilities began in 2004. In 2006, the City of Richmond Municipal Codes were revised to require that new FHS’s install grease pretreatment devices that conform to the current version of the UPC. Continued accumulation of grease in the collection system is calling for increased effort to control discharge of grease.

Baykeeper responds to the City’s FOG program
In 2006, Baykeeper brought a lawsuit against the City of Richmond for its excessive Sanitary Sewer Overflows. One component of the settlement agreement was that the City of Richmond needed to increase its inspection frequency of food service establishments, and improve their public education and outreach program.

Goals
State Water Resource Control Board adopted Order 2006-0003-DWQ which calls for owners of sanitary sewer collection systems to develop Sanitary Sewer Management Plans (SSMP) to reduce potential for sanitary sewer overflows. A component of the model plan requires a fats, oils, and grease (FOG) control program. This document summarizes the City of Richmond’s FOG Source Control Program.

Justification for the FOG Program
The justification of sewer line preventive maintenance (hydro-jetting), FOG buildup in lift stations, the volume of grease collection and removal at the WWTP and the more than 165 commercial FOG generators in the service area conclude that a FOG program is warranted.

3 Disposal of FOG Within Richmond Municipal Sewer District FOG discharge to the sewer is prohibited. Users are required to properly dispose of pretreatment wastes (brown grease) and cooking grease (yellow grease).

At present time, the City of Richmond CANNOT accept any amount of grease for disposal at the Richmond Water Pollution Control Plant.

Commercial/Industrial
However, there are other facilities near the City of Richmond who will accept FOG for a fee. They are listed in Attachment A.

There are several commercial/industrial FOG Waste hauling Companies serving Contra Costa County. They are listed in Attachment B.

Residential
The City of Richmond has a food recycling program for Residents that allow them to mix their grease in with their food scraps. This is the “green can” recycling program. This waste is not hauled to the local landfill, but used as composting.

See “Pretreatment System Maintenance” for other requirements Cleaning Maintenance Schedule and FOG Blockages
Problem Area Identification
A FOG problem area is identified by a line blockage determined to be the result of FOG or segments of the sewer where preventive maintenance has identified accumulations of FOG. Potential FOG problem areas consist mainly of trunk line segments in commercial districts that serve a concentration of food service facilities. Problem areas also appear to be associated with multi-family dwelling complexes, although sewer back-ups at these sites appear to be due a combination of factors, including grease, line sags, and roots. Any commercial facility that prepares food is considered a FOG generator.

Sewer Line FOG Obstruction/Blockage Preventive Maintenance Program
Prevention of FOG-related interference to the sewer system consists of a two-prong approach: scheduled preventive maintenance (PM) of problem areas and source control. Hydro-jetting is the most common method of truck line preventive maintenance. Known problem areas are prioritized based on qualitative findings of previous preventive maintenance results, such as a surcharged condition or significant grease collected on the jetting nozzle. High priority segments are put on a quarterly preventive maintenance schedule and the findings are forwarded to the Source Control Program for follow-up. The segment will remain on a quarterly PM until subsequent 4 observations determine that potential for obstruction or blockage have been reduced or eliminated.

SSMP Enhanced FOG Source Control Program
The City of Richmond has an approved Pretreatment Program. The FOG component is being enhanced by adding food handling facilities to the program’s waste discharge permit program and increasing public outreach.

The City of Richmond’s Source Control program staff manages plan check and specifications for newly constructed and remodeled FHF’s to ensure items required by the Richmond Municipal Code are completed prior to approval of building permits.

New buildings constructed to house food handling facilities are required to include a covered area for a dumpster. If the area cannot be covered, the facility must ensure that the dumpster is covered and the area is designed to prevent any water run-on to the area and run-off from the area. Any drains installed in the area must be connected to a grease removal device and must be protected so that no stormwater from the area is discharged to the sanitary sewer.

The City of Richmond’s Finance Department also issues a new listing each month for every business who files for a Business License in the City of Richmond. This list is reviewed by Source Control Program staff to ensure that all FHF’s that are listed are inspected and, if necessary, issued a FOG wastewater discharge permit.

Legal Authority to Prohibit Discharges – Sewer Use Ordinance Sanitary Sewer Use Ordinance
The City of Richmond Sewer Use Ordinance provides the legal authority to implement the pretreatment program for FOG. A summary of the enabling authority as follows:

Administration
The City of Richmond Engineer is charged with implementing a source control program throughout the Richmond Municipal Sewer District service area. The City of Richmond Source Control Division administers the source control program. Building Regulations issue permits for installation of grease control devices in conformance to requirements of the Uniform Plumbing Code.

Installation of Grease Removal Devices
Design and Sizing
The ordinance(s) provides the following direction. The requirement is implemented by the Source Control Program.
x FOG separators and grease interceptors shall be provided, at the User’s expense, where, in the opinion of the City Engineer, they are necessary for the proper handling of wastes containing these substances in excessive amounts, or any flammable wastes or harmful ingredients.
x All grease interceptors shall be of a type and capacity approved by the City Engineer, and shall be located so it is readily accessible for inspection and cleaning.
x FOG separators and grease interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature.

They shall be of substantial construction and equipped with removable covers.

6 Pretreatment System Maintenance
x Facilities must have a FOG Maintenance Management Program and/or Wastewater Discharge Permit.
x A grease collection service shall be required for all facilities that generate FOG. x Dishwashers and food grinders are prohibited from discharging through the grease trap pursuant to the State of California Uniform Plumbing Code. x Grease interceptors shall be cleaned out completely by a FOG collection service as necessary to assure that the grease interceptor will operate as designated at all times or as otherwise specified by the City of Richmond. x Maintenance records indicating date of service, volume pumped, name of waste hauler, and waste disposal location for each pumping of the grease interceptor must be kept for a minimum of three (3) years. The records must be provided to the Source Control Program Inspector when requested during normal business hours.
x Pumped out FOG shall NOT be returned to the sewer system, nor any private wastewater system, nor storm drains.
x If significant grease accumulation (e.g., partial blockage) is found downstream of the process of concern, a Source Control Inspector and/or the City Engineer may inspect the facility.
x If a business is shown to be the cause of a grease-related sewer overflow the User will be responsible for the cost of clean-up as set forth in Section 12.18.140.

Authority to Inspect - Waste Discharge Permits
Policy and Applicability
The waste discharge permit program as applied to the FOG source control is summarized as follows:
x Issue waste discharge permits to facilities that are required to have pretreatment systems.
x Food handling facilities are required to have pretreatment systems. x A food handling facility is defined as any facility that prepares and/or services food for commercial use or sale.
x FOG pretreatment system maintenance frequency is established in inspection reports based on a grading system. The higher the grading number, the more frequently a facility will be inspected. The numbering system is based on a scale of 1 – 5).

Permit Contents
The Food Handling Facility permit package consists of the facility information and specific requirements page, Best Management Practices (Attachment C), Maintenance Log Sheet (Attachment D), and Employee Training Record (Attachment E). Waste Discharge Permits follow a standard format for all applications and contain the following provisions:
7 x Designated industrial waste streams shall discharge through pretreatment system indentified in the permit.
x Bypass or modification of waste treatment systems is strictly prohibited. x Maintain waste treatment systems per manufacturer instructions or at frequency as indicated in permit, which ever is more frequent. Maintenance is defined as removal of collected contents and the unit kept in optimal physical/mechanical condition.
x Keep records of waste treatment system maintenance, including pumping and/or cleanout dates, and disposition of treatment system wastes. x Conform to reporting requirements as mandated.
x Do not discharge any hazardous waste or other problem wastes. x Notify the City of Richmond immediately of any abnormally high volume or concentration of waste discharge that has occurred or is imminent. x Train employees on waste discharge requirements, including pretreatment system maintenance recommendations and requirements, and best management practices.

Inspection and Enforcement
Inspections are conducted to assess compliance with permit requirements. Compliance is determined by visual inspection of the Pretreatment system, interview with owner/staff about general operations and waste handling; and documentation of Pretreatment maintenance, Pretreatment waste disposition and employee training. A copy of the inspection form is attached (Attachment F).

Regulatory/Outreach Strategy
Commercial/Industrial Component
The current commercial program consists of periodic inspections of commercial food handling facilities. We have expanded that list to include schools, churches, and health care facilities. The rationale behind that is:
x Schools operate on a seasonal basis and could be a large contributing factor of grease due to lack of knowledge of interceptor systems. x Maintenance of grease traps and interceptors for schools are largely performed by staff that may not be located on site, therefore “out of site, out of mind” philosophy exists and we need to educate on-site staff regarding the problems the school could be creating.
x Church functions operate on weekends and rarely have staff “in the know” of how to properly dispose of grease. Initial inspections indicated that most do not have adequate grease removal devices. The Source Control program will provide BMP material that educates church staff to practice “From the Pan to the Can”. 8 x Health care facilities (skilled nursing homes) prepare meals for their patients, but did not fall under any of normal commercial food handling facility categories.

Most of them did have large grease traps. However, they were not being maintained on a regular basis. We have added them to our regular inspection schedule and placed them on permit.
x Posters for BMP’s for handling FOG are distributed. The Bay Area Pollution Prevention Group (BAPPG) funded CalFOG to create a poster that is available in English, Spanish, Korean, Chinese, and Vietnamese. These posters are printed by the City of Richmond in any language the Facility should request.

Multi-family/Residential Component
The Residential Outreach Element includes:
x Dispensing of educational brochures at public facilities (libraries, schools, etc.), and issuing public service announcements, and updating our “What’s New” on the web page to remind residents how to properly dispose of their deep fat fryer grease, etc.
x We meet with Richmond Neighborhood Coordinating Council periodically to discuss various topics. We provide them hand-outs for their local Neighborhood Groups regarding the proper disposal of grease.
x FOG door hangers are distributed in areas where the Collection Crew has reported a back-up due to grease.
x Food Scrapers, with the City of Richmond’s insignia and information about the FOG program, are also left as door hangers in areas where excessive grease is reported by the Collection Crew and in areas where a back-up has occurred due to grease.

West Contra Costa County Residents Only
Thinking of frying a turkey for the holidays? Not sure what to do with the leftover used cooking oil and grease?
Never wash cooking fats, oil or grease down the drain, as they can cause the sewer line to back up into your home, streets and storm drains which flow to the Bay. Instead recycle it! EBMUD and the West Contra Costa Integrated Waste Management Authority have partnered to provide a free drop-off program. Most cooking fats will be turned into bio diesel. Please do NOT mix with automotive waste and no restaurants will be serviced.

Fifteen (15) gallons per person maximum.

We also accept many household hazardous wastes, so load up old paint and pesticides and just make one trip. Remember to keep all wastes in separate containers -- never mix different substances. Visit www.recyclemore.com for a list of acceptable household hazardous waste or call 1-888-412-9277.

The grease and food that
remains in pots, pans, and
dishware will likely go to
the landfill. By "dry wiping"
and disposing in garbage
receptacles, the material will
not be sent to the grease
traps and interceptors.

This will reduce the
amount of material
going to grease traps
and interceptors,
which will require
less frequent
cleaning, reducing
maintenance costs.

Observe dishwashing practices.

Dispose of food
waste by recycling
and/or solid waste
removal.

Some recyclers will take
food waste for animal feed.

In the absence of such
recyclers, the food waste can
be disposed as solid waste in
landfills by solid waste
haulers.

Recycling of food

Service Establishment
Pretreatment Inspection Tips
Cover outdoor
grease and oil
storage containers.

Some local
jurisdictions will
have BMPs in place
for
storm water also.

Uncovered grease and oil
storage containers can collect
rainwater. Since grease and
oil float, the rainwater can
cause an overflow onto the
ground. Such an overflow
will eventually reach the
storm water
system and
nearby streams.

The discharge of
grease and oil to the
storm drain system
will degrade the water
quality of receiving
streams by adding
biological and
chemical oxygen
demand to the stream.

Discharge of grease
and oil to the storm
drain might also result
in legal penalties or
fines.

Observe storage area for signs
of oil and grease.

Inspect containers for covers.

Remove covers to ensure
containers have not overflowed
and do not have excess water.

Locate grease
dumpsters and
storage containers
away from storm
drain catch basins.

The farther away from the
catch basin, the more time
someone has to clean up
spills or drainage prior to
entering the storm drain
system.

Be aware of oil and grease
dripped on the ground while
carrying waste to the
dumpster, as well as
oil and
grease that may "ooze" from
the dumpster.

Pretreatment Inspection Tips
Witness all grease trap
or interceptor
cleaning/maintenance
activities to ensure the
device is properly
operating.

Grease trap/interceptor
pumpers may take
shortcuts. If the
establishment manager
inspects the cleaning
operation and ensures it is
consistent with the
procedures in the section
on
Grease Trap and
Interceptor Maintenance
they are more assured of
getting full value for their
money.

The establishment
will ensure it is
getting value for the
cost of cleaning the
grease trap or
interceptor.

Ot
herwise the
establishment may
be paying for
cleaning more often
than necessary.

None.

Clean under sink grease
traps weekly, or more
frequently, if needed.

If grease traps are more
than 50% full when
cleaned weekly, the
cleaning frequency
needs to be increased.

Under sink grease traps
have less volume than
grease interceptors.

Weekly cleaning of under
sink grease traps by the
establishment’s own
maintenance staff will
reduce the cost of cleaning
the grease interceptor.

If the establishment does
not have a grease
interceptor, the under sink
grease trap is the only
means of preventing
grease from entering the
sanitary sewer system. If
the grease trap is not
providing adequate
protection, the local sewer
agency may require
installation of a grease
interceptor.

This will extend the
length of the
cleaning cycle for
grease interceptors
that the
establishment
maintains.

Visually inspect the contents
of the under sink grease trap.

Inspect cleaning records.

Clean grease
interceptors routinely, at
least monthly.

Grease interceptors must
be cleaned routinely to
ensure that grease
accumulation does not
cause the interceptor to
operate poorly.

The cleaning frequency is
a function of the type of
establishment, the size of
the interceptor, and the
volume of flow discharged
by the establishment.

Routine cleaning
will prevent
plugging of the
sewer line between
the food service
establishment and
the sanitary sewer
system. If the line
plugs, the sewer line
may back up into the
establishment, and
the business will
need to hi
re
someone to unplug
it.

Interceptor should have no
more than 1/3 the depth as
grease, and,
Interceptor should have no
more than 1/4 the depth as
sediment,
and
No more than 25% of the
depth should be a
combination of grease (top)
and sediment (bottom).

Keep a maintenance log. The maintenance log
serves as a record of the
frequency and volume of
cleaning the interceptor. It
is required by the
pretreatment program to

ES-1 City of Richmond\Veolia
November 2011 Collection System Master Plan
o\c\356\02-10-05\wp\nov\122910_ES
Executive Summary
In June 2010, Veolia Water (Veolia), the contr act operator for the City of Richmond (City) collection system, retained West Yost Associates (West Yost) to complete a wastewater collection system master plan. The master plan assesses the conveyance capacity of the City’s collection system within the Richmond Municipal Sewer District (RMSD). The draft Master Plan was completed in March 2011. Since this time , additional flow monito ring and alternatives analyses have been conducted, and some prio rity projects are underway. In November 2010, the City and Veolia asked West Yost to update the Master Plan to reflect the recent findings and activities.

ES.1 BACKGROUND AND INTRODUCTION
The primary purpose of this sewer collection system master plan (Master Plan) is to evaluate the City of Richmond gravity sewer collection sy stem under a specific design storm, using a computerized hydraulic model, to determine whether the system can convey flows without sewer system overflows (SSOs). Where SSOs are predicted by the hydraulic model, this Master Plan provides recommended solutions.

The City and Veolia have developed two pr ior master planning studies, in 2006 and 2007.

However, both of these studies relied on incomple te flow data. As a result, neither of these studies was able to replicate syst em operational conditions or to identify surcharge and capacity issues to the level of assurance of this Master Plan.

In 2010, the City and Veolia completed a new fl ow monitoring study upon which this Master Plan is based. In 2011, Veolia conducted additional flow monitoring with a specific focus on measuring tidal response in the southern portion of the system. The 2010 and 2011 flow monitoring studies were successful in capturing fl ow data throughout the system during several reasonably sized storm events and additional tidal events. This Master Plan benefits from this additional data, and is intended to supersede the prior planning studies completed by the City and Veolia for the sewer collection system.

This Master Plan is comprised of the following nine chapters:
x Chapter 1 – Introduction
x Chapter 2 – Existing Wastewater System
x Chapter 3 – System Flows
x Chapter 4 – Flow Monitoring Program
x Chapter 5 – Hydraulic Model Development
x Chapter 6 – Planning Criteria
x Chapter 7 – Capacity Analysis
x Chapter 8 – Pipeline Repair and Replacement Program
x Chapter 9 – Capital Improvement Plan

Executive Summary
ES-2 City of Richmond\Veolia
November 2011 Collection System Master Plan
o\c\356\02-10-05\wp\nov\122910_ES
The Master Plan was developed to meet the following objectives:
x Evaluate system-wide flow characteristics to identify areas contributing to high inflow and infiltration (I&I);
x Assess the existing hydraulic capacity of the collection system; x Evaluate modeled pump station firm capacity under design storm conditions; x Summarize previously developed pipeline condition and replacement needs; and x Develop a prioritized capital improvement program (CIP) that strategically replaces or repairs facilities over time to first meet the requirements of the settlement agreement between the City and San Francisco Baykeeper, and also provide long-term system reliability.

The recommendations that are presented in this Master Plan must be considered in conjunction with proposed improvements at the City’s wastewater treatment plant. Master planning activities for the treatment plant are in progress by ot hers. The success of the recommended collection system improvements in addressing wet weather sewer system ove rflows (SSOs) depends on the City’s ability to maintain 42 million gallons per day (mgd) of pumping capacity 1 at the
wastewater treatment plant influent pump station, and subsequently, to maintain or exceed this capacity in the primary and secondary processes at the plant.

ES.2 EXISTING WASTEWATER SYSTEM
The City’s Richmond Municipal Sewer District (RMSD) provides wastewater collection service to a majority of the City of Richmond, as well as a small area within unincorporated county limits, all located within Contra Costa County in the San Francisco Bay Area. The City of Richmond and RMSD collection system service area are shown on Figure ES-1.

Abutting the City of Richmond’s service area, West County Wastewater District (WCWD) provides sewer collection service to a small portion of the City on the northern border of the City, adjacent to the City of San Pablo, and Stege Sanitary District (Stege) collects wastewater for a portion of the City in the eastern hills, adjacent to the City of El Cerrito. The City, WCWD, and Stege convey flows to three separate wastewater treatment plants.

The City’s existing sewer collection system is comprised of approximately 187 miles of active gravity sewer pipelines with sizes ranging from 4 to 66 inches in diameter, 15 miles of pressure pipelines, and 14 pump stations, according to the California Integrated Water Quality System (CIWQS) database. The City conveys all flows to its wastewater treatment plant that is located on Canal Boulevard, south of I-580. Information on the existing system is summarized in this section and is also presented in Chapter 2 of this report. 1 Maximum influent pump station pumping capacity as provided by Veolia.

o\c\356\02-10-05\wp\nov\122910_ES
ES.2.1 Population Served & Land Use Characteristics
The estimated population for the City of Richmond is 103,701 based on the 2010 census. The City’s RMSD service area includes a wide range of mixed land uses, as shown in Figure ES-2.

These land uses were provided by the City a nd were supplemented with Contra Costa County public GIS resources.

ES.2.2 Collection System Facilities
The City’s sewer system is comprised of appr oximately 187 miles of pipe ranging in diameter from 4 to 66 inches. The predominant pipeline material for small diameter pipelines is vitrified clay pipe. The City’s service area is comprised of ten sewer drainage basins. Flows from each of the sewer basins were monitored by the City u nder a flow monitoring program that began in February 2010 and was concluded in June 2010. This flow monitoring program collected system data and also collected additi onal flow data to pinpoint the impact and locations of tidal infiltration in the southern portions of the serv ice area. A subsequent flow monitoring study to further evaluate tidal inflow was completed in July 2011.

The City owns and operates 14 pump stations. Three of these pump stations, Canyon Estates 1, 2, and 3, are considered outside of the RMCD service area because they discharge to the Stege Sanitary District. Five of the City’s pump stations were included in the hydraulic model; these stations, which include the Kelle r Beach, Ferry Point, ICI, Mari na Bay Cove, and Marina Bay Parkway pump stations each convey flow directly to a modeled trunk sewer.

ES.2.3 Overview of Legal and Regulatory Mandates
Veolia and the City operate and maintain the City’s collection system plant in accordance with a number of regulatory documents, including:
x Regional Water Quality Control Board (RWQCB) National Pollution Discharge Elimination System permit,
x RMSD Sewer System Management Plan (SSMP), and
x 2006 City of Richmond-Baykeeper settlement agreement.

These mandates form the basis for recommendati ons in the Master Plan, and are discussed further in Chapter 2 of this report.

ES.3 SYSTEM FLOWS
Sewer system dry weather flows were estimated using land use information, unit flow factors, aerial photography, industrial discharge data, service area boundary data, the sewer network, and data collected during the City’s 2010 flow monitoring program.

Land use information was provided in GIS format from the City of Richmond, and supplemented by public GIS information available through Contra Costa County. The City also provided West Yost with industrial wastewater discharge data. These flows were added as calculated point loads to the more generalized land use-based fl ows more accurately depict basin-specific dry weather flows.

Executive Summary
ES-4 City of Richmond\Veolia

o\c\356\02-10-05\wp\nov\122910_ES
Because the RMSD service area limits are not the same as the City limits, parcels that straddled the service area boundary were included or excl uded from flow calculations using a 50 percent rule. This rule included flow from parcels when at least 50% of the parcel’s area was included within the service area boundary. There were nume rous exceptions to this rule, as defined in Chapter 3 of this report.

The City’s demographics and stable population base justified calculation of average dry weather flow using unit flow factors and land use design ations. Flow factors for each land use category, ranging from very low residential to various cate gories of commercial and industrial uses were developed and applied to the la nd use on a sewershed by sewershe d basis (the system included 883 individual sewersheds).

Flows from twelve large industries as provided by th e City were then added to the calculation to ensure that the absence of large discharger data would not skew calculated results. The combined flows were then adjusted until calculated flows per basin were within approximately ten percent of measured flows. The segregated industries included the following:
x Chevron
x Department of Health Services
x Bio-Rad Laboratories
x Kinder Morgan
x Kaiser Foundation
x California Fats and Oils
x West Contra Costa Unified School District
x Social Security
x U.C. Richmond Field Station
x Catellus Development Corp
x U.C. Regents
x T&T Richmond LP
Diurnal patterns were applied to the flows to most accurately represent flow patterns that were measured during the flow monitoring program.

ES.4 FLOW MONITORING AND INFLOW & INFILTRATION ANALYSIS In early 2010, the City and Veolia completed a system-wide flow monitoring program. The program was conducted by V&A from February to June 2010. In addition, from May 2010 to June 2010, five additional flowmeters were installed at new locations within the southern portion of the service area to refine and supplement data for areas with tidal inflow and high groundwater infiltration. In July 2011, six flowmeters were installe d in the southern basins to further evaluate potential tidal inflows. Data and results are presented in the V&A reports titled, Flow Monitoring and Inflow/Infiltration Study (D ecember, 2010, Flow Monitoring of Five Tidal Sites (September, 2010), and Sanitary Sewer Fl ow Monitoring and Tidal Inflow and Infiltration Executive Summary
ES-5 City of Richmond\Veolia
November 2011 Collection System Master Plan
o\c\356\02-10-05\wp\nov\122910_ES
Study (September, 2011) . The V&A Reports are included in Appendix B. The flow monitoring program and results are discussed further in Chapter 4 of this report.

The flow monitoring program included twelve (12) gravity meters that measured flows from ten basins, and two (2) rain gauges. Figure ES-3 prese nts the flow meter locations and associated collection system basins. The basins were named by West Yost in development of the hydraulic model.

The 2010 flow monitoring program captured rainfall ev ents with a statistical recurrence interval of less than 2 years ( i.e., 50 percent probability of occurring in any given year) through twelve gravity meters that measured flows from ten dr ainage basins. Peak flows generated by these rainfall events resulted in surcharge conditions in all but two of the metered locations throughout the collection system.

The primary contributors to wet weather I&I in the City’s system are 1) direct tidal inflow in the southern basins, 2) groundwater infiltration including a tidal saturation infiltration component, 3) storm runoff inflow from direct connections between stormwater facilities and the sewer system, and 4) rainfall dependent infiltration.

The highest level of tidal infl ow was found in the southern sewer basins. After the flow monitoring period, Veolia addressed several sources of tidal inflow through the installation of duck-bill check valves on the wet weather outfall structures. The 2011 flow monitoring effort has confirmed the positive impact that these activities have had on reducing tidal inflows. The highest levels of rainfall depend ent inflow and infiltration (RDII) were found in the Castro, 1 st
Street, and Canal Boulevard basins, which were monitored by Meters 1, 3, and 4, respectively.

ES.5 CAPACITY ANALYSIS
A capacity analysis was conducted using a computer-based hydraulic model of the City’s RMSD wastewater collection system, developed usin g Innovyze® InfoWorks™ CS software. The hydraulic model includes the City’s main trunk se wers (typically 12-inch diameter and larger) and associated facilities, and is a skeletonized representation of the City’s RMSD sewer system in its configuration and operation. This section summarizes the components of the capacity analysis that are discussed further in Chapter 5 of this report.

Veolia Water developed the hydraulic model ne twork and provided this network to West Yost for further development and analysis. The hydrau lic model comprises a sk eletonized network of nodes (e.g., manholes) and conduits (e.g., pipelines).

The structural components of the hydraulic model network, ( i.e., nodes and conduits) were initially developed by Veolia st aff and provided to West Yost in September 2010. The hydraulic model consists of approximately 47 miles of sewer pipeline ranging in diameter from 4-inches to 66-inches. The model includes all 12-inch diameter and larger trunk lines, and associated manholes and lift stations. Many 10-inch diameter pipelines have been included, as provided by Veolia staff, as well as 4-inch, 6- inch and 8-inch diameter lines in selected areas as needed to provide connectivity. The 47 miles of pipeline represent approximately 25 percent of the City’s RMSD system.

Executive Summary
ES-6 City of Richmond\Veolia

o\c\356\02-10-05\wp\nov\122910_ES
Five of the City’s fourteen pump stations are included in the hydraulic model: Marina Bay Parkway, ICI, Ferry Point, Marina Bay Cove, and Keller Beach. In addition, the hydraulic model includes the influent pump station wet well at the wastewater treatment plant. Figure ES-4 shows the RMSD sewer network and modeled assets.

ES.5.1 Dry Weather Flow Generation
West Yost delineated 883 subcatchments within the hydraulic model. Subcatchments were generally defined to encompass a single land use that flows to a single model node. Wastewater flows were generated for each subcatchment or sewershed, and were comprised of one or more of the following components:
x Base wastewater flow (BWF);
x Tidal saturation infiltration (TSI), which results when tidal activity saturates the soil and infiltrates into the pipeline network through defects in the system, during dry weather and wet weather periods; and
x Rainfall-dependent Infiltration and Inflow (RDII).

Base wastewater flows were calculated based on land uses, with the exception of twelve industrial point loads that were provided by the City and applied to specific nodes. For the City’s hydraulic model, industry-standard unit flow fact ors (verified through flow monitoring data) were applied to land use to generate BWF. Diurnal patterns were applied to the flows in each monitoring basin as needed to match the flow pattern in each basin to measured flows.

Tidal Saturation Infiltration (TSI) was then in cluded in the model to account for measured groundwater infiltration in the southern sewer basins. TSI wa s calculated using base flow measurements that were consistently present and that exceeded anticipated dry weather flows during off-peak (i.e. , nighttime) hours. Calculated TSI was distributed across selected pipe segments based on the product of pipe diameter and length.

These dry weather flows were calibrated within the hydraulic model to closely reflect measured flow values. The average dry weather weekday flow measured during the 2010 flow monitoring period was 6.3 mgd.

ES.5.2 Wet Weather Flow Generation
The City’s model uses the RTK method to calculate wet weather inputs to the hydraulic model.

The RTK method generates hydrographs from each subcatchment that represent flows during and immediately after rainfall events caused by seepage of water into the collection system. The RTK method generates a series of three triangular hydrographs that represent short-term, medium-term, and long-term rainfall response. The RTK parameters include:

1. R is the area of the graph representing the portion of rainfall falling on a subcatchment that enters the sewer collection system.

2. T is the time from the onset of rainfall to the peak of the triangle.

3. K is the ratio of the “time to recession” to the “time to peak” of the hydrograph.

Executive Summary
ES-7 City of Richmond\Veolia
November 2011 Collection System Master Plan
o\c\356\02-10-05\wp\nov\122910_ES
RTK parameters were adjusted by basin, beginning with the upstream basins, until measured flows during the calibration storm closely ma tched model-generated flows in temporal distribution and volume.

Tidal Inflows (TI) were also included in the model for use during wet weather flow simulations.

TI were derived to represent measured flows in excess of dry weather flows during non-rainfall periods.

During the calibration storm, significant surcharging occurred throughout the system. During the flow monitoring period, incoming flows exceeded the available pumping capacity of the WWTP’s influent pump station and the wet well water level rose to its maximum level. The wet well level created a hydraulic gradeline that was carried back through all of the low-lying portions of the service area. As a result, in some basins, measured flow peaks were difficult to replicate in the model.

However, despite the surcharge condition, only one meter, Meter 10, ex perienced consistent backwater effects. Therefore, the data collected during the calibration storm was sufficient to calibrate the hydraulic model to measured flow volumes and general flow patterns. The peak hourly measured wet weather flow during the flow monitoring season was approximately 33 mgd.

ES.6 PLANNING CRITERIA
Planning criteria addresses items such as collection system capacity, gravity sewer slopes, and maximum depth of flow. As required by the City-Baykeeper settlement agreement, the City evaluated the system under a design storm with a recurrence interval of 10 years ( i.e., 10 percent probability of occurring in any given year) and duration of 24 hours.

Flow characteristics for the 10-year, 24-hour de sign storm were derived from data that is maintained by the Contra Costa County Flood Control District. Using the County’s depth-frequency-duration curves in conjunction with the County’s Mean Seasonal Isohyet map, total rainfall depth of 4.2 inches was used to represent a 10-year, 24-hour design storm in the City of Richmond. This rainfall depth was th en distributed using the Natural Resource Conservation Service SCS Type 1 rainfall distribution curve.

Pipelines were considered to have a capacity deficiency when, under peak wet weather flow conditions for the design storm, the water leve l or hydraulic grade line (HGL) exceed ground surface level.

A lift station was considered capacity deficien t if the station did not have sufficient firm capacity, i.e. capacity with the largest pump out of serv ice, to convey peak hourly flows during the design storm. Based on pump station characteris tics that were documented in the City’s prior master planning efforts, all pump stations were sufficiently sized to convey design flows.

New or replacement pipelines were sized to convey model-generated peak flows without significant surcharge. Capacity constraints we re addressed through th e addition of parallel pipelines, located along the same alignment a nd depth as the existing, surcharged pipe.

Optimized pipeline alignments were not included this Master Plan. Optimizations to pipeline Executive Summary

o\c\356\02-10-05\wp\nov\122910_ES
alignments and flow diversions should be cons idered during the preliminary design phase for each project.

ES.7 HYDRAULIC CAPACITY ANALYSIS RESULTS
The City's modeled collection system network wa s evaluated for its capacity to convey flows that are predicted to occur during a design storm event. The analysis was completed using a design storm with a published recurrence interv al of 10 years and duration of 24 hours (10-year, 24-hour design storm). The system was evaluate d for its ability to convey all flows from the design storm without overflows. Recommended capacity assurance projects are shown in Figure ES-5. Additional information on the projects listed below is presented in Chapter 7 of this Master Plan.

Due to the relatively flat topography of the lower third of the service area, wet weather flows are significantly impacted by the operating level at the wastewater treatment plant influent pump station. The proposed capacity improvements reduce flows to the wastewater treatment plant to more closely match the influent pump station capacity of 42 mgd. Flows are controlled through the addition of a new relief sewer and wet weather storage facility. Following the wet weather event, stored flows are conveyed through existing pipelines to the treatment plant.

The hydraulic model identified the need to store flows of approximately 7.5 million gallons during the design storm event, in order to control and reduce flows to the treatment plant. The preferred location for wet weather storage is a location near or within the existing Chevron facility at West Gertrude Av enue and Richmond Parkway. This location has received preliminary discussion between the City and Chevron regarding the potential for Chevron to allow the City to use the basins as wet weather storage, thereby establishing a beneficial use for the facility as desired by Chevron. Chevron belie ves that they have up to 20 million gallons of storage available for use by the City for wet weather storage.

The storage location would include a pumping facility to return flows back to the system after the rainfall event. The storage facility would incl ude pre-screening, and should be designed to maximize scouring velocities a nd minimize odors. Storage will likely require the acquisition of easements and/or property, as well as community endorsement. The addition of storage will require environmental clearance under the California Environmental Quality Act.

The hydraulic model identified eight project areas where the water surface or hydraulic gradeline exceeded the ground surface elevation. These locations were identified as having sewer system overflows during the design storm event. General descriptions for the associated capacity improvement projects are listed below. More detailed information on each project is presented in Chapter 7 of this Master Plan.
x Hensley Street Capacity Improvements. 3.8 miles of relief sewers conveying flows from the northern half of the service area west, to a new storage location near the existing Chevron pond facility.
x Cutting and Hoffman Boulevard Sewer Capacity Improvements – 2.4 miles of relief sewers from Carlson Boulevard to Harbour Way South, and along Hoffman Boulevard south of Cutting Boulevard.

x 1st Street, MacDonald, and Virginia Ave nue Sewer Capacity Improvements - 1.8 miles of relief and replacement sewers from Pennsylvania and 4th Street down to 1st Street and West Cutting Boulevard, on MacDonald Avenue near 23 rd Street, and on Virginia Avenue near Harbour Way.
x San Pablo Avenue and Carlson Boulevard Sewer Capacity Improvements – 1.7 miles of new and relief sewers from Amador Street and Eas tmond Avenue to San Pablo Avenue, ending at the intersection of Richmond Greenway Trail and South 47th Street, and on Carlson Boulevard.

The hydraulic model identified sufficient capacity in each of the five modeled pump stations to convey design flows. In addition to the five m odeled pump stations, the City operates nine smaller stations within the sewer collection system. This Master Plan did not assess the capacity of these smaller stations to conv ey design flows. As trunk sewers and associated infrastructure are replaced over time, the City should review th e firm capacity of th ese unmodeled collection system pump stations.

Table ES-1, also presented as Table 7-4 in th e report, summarizes the capacity improvement projects and associated costs. Construction costs include the total construction cost estimate including contingency. Total costs add project design and construction administration to the total construction cost.

ES.8 PIPELINE REHABILITATION AND REPLACEMENT PROGRAM
This Master Plan scope included a review and reprioritization of previously-generated system rehabilitation and replacement (R&R) projects. Two documents previously prepared by West Yost summarize the City’s previously-defined R&R needs, which are also listed in priority order below. These documents are included as an appendix to Chapter 8 of this Master Plan. x Elimination of stormwater inflow: This description includes multiple projects over time to systematically address sources of tidal inflow into the collection system.

x Cypress Point sewer replacement project: Original a component of the Keller Beach interceptor replacement project, this project has been identified as a standalone project due to its criticality and history of sewer system overflows. x Keller Beach interceptor replacement project: This project replaces existing pipelines and collectors sewers in the Point Richmond neighborhood of the City. A large portion of the interceptor system is submerged within the San Francisco Bay. x Ongoing pipeline repairs and replacements: This project summarizes point repairs and pipeline replacements that were previously identified to eliminate the City’s most significant pipeline structural defects, including pipe failures and significant offsets.

ES.9 PRIORITIZED CAPITAL IMPROVEMENT PLAN
Chapter 9 of this Master Plan presents the recommended Capital Improvement Program (CIP) for the City’s RMSD gravity sewer collection system. The recommended CIP identifies the needed improvements at a master planning level, and does not constitute conceptual or preliminary design of these improvements. Subsequent alignment studies and preliminary designs are required to finalize pi peline configuration and alignmen t, and to determine the final sizes, locations, and details of the proposed improvements.

The CIP was developed to create a fundable prog ram that addresses the City’s competing needs for capacity improvement and reliability. The fo llowing criteria were used to prioritize the various projects and develop a timeline for implementation. x Projects to Eliminate SSOs in compliance with the existing settlement agreement between the City and San Francisco Baykeeper.
x Projects to Reduce Maintenance-Related SSOs, including critical condition-related rehabilitation projects and projects that are needed to render the collection system pipes accessible to CCTV inspection equipment.

The proposed CIP begins implementation in Fisc al Year 2011/12 and extends into Fiscal Year 2020/2021. The total estimated 10-year CIP cost is $98.5 million. Of this amount, $60.2 million is needed to meet the capacity requirements that are included in the City-Baykeeper settlement agreement, and are recommended for completion within the Baykeeper settlement agreement timeframe. If this schedule is not achievable, these improvements are recommended within the 10-year CIP timeframe. The remaining costs were spread through the 10-year timeframe of this CIP, but can be further distributed into future programs.

The City-Baykeeper settlement agreement requ ires completion of the proposed capacity improvement projects by Septem ber 1, 2014. However, the schedule for implementation of the capacity improvements is constrained by the timeframe needed to secure environmental clearances for the proposed storage project, which must be initiated first, as well as currently available funds. Therefore, as desired by the City and Veolia, projects needed to provide in-system storage are planned for completion by 2013/14, in order to substantially meet the contractual requirement. The storage facility will help address the most significant historical capacity issues for the City, including the two combined sewer/stormwater discharges to the Richmond Inner Harbor. The remaining pipe line capacity improvements will eliminate more localized predicted sewer system overflow issues over time. If the City is able to implement the Executive Summary
ES-11 City of Richmond\Veolia
November 2011 Collection System Master Plan
o\c\356\02-10-05\wp\nov\122910_ES
proposed project on an accelerated schedule, then the project implementation timelines will be adjusted accordingly.

The proposed rehabilitation projects that are discussed above provide needed ongoing rehabilitation on a parallel track with the City’s capacity improvements. The estimated cost of the City’s priority rehabilitation and replacement projects is $28.3 million.

The balance of the CIP provides a $10 million placeholder for unknown project that arise during the implement of the capital program. This ite m includes the project needed to eliminate the Harbour and Wright overflow structure that is currently under discussion outside of the recommendations of this master plan.

The proposed CIP is presented as Table ES-1, and again as Table 9-1.

ES.10 NEXT STEPS
This Master Plan is designed to be a working document that is updated over time to reflect current knowledge about system issues and needs. The City’s highest priority in the implementation of the Master Plan recommendations is to address SSOs to meet the requirements of San Francisco Baykeeper, and to meet the requirements established by the Regional and State Water Resources Control Board. The following specific tasks are recommended in the near term as the City implements the recommendations in this Master Plan:
x Conduct system-wide wet weather flow and rainfall monitoring in 2011/12, and include locations in the system that are needed to refine the requirements of the proposed Barrett Avenue Relief Sewer project. The objective of the 2011/12 flow monitoring program is to capture additional data that will assist in refining model development and calibration in order to remove possible conservatism in predicted results. x Complete the I&I reduction projects (pipeline rehabilitation and replacement) that are currently underway. After the current projects are completed, the City should consider conserving remaining available funds for capacity improvement projects and emergency/urgent rehabilitation needs.
x Continue planning activities for the Hensley Street Wet Weather Storage project, and begin planning and design for the other proposed capacity improvement projects. x Confirm that the City’s permitted dry weather flow dischargers are holding flow during periods of dry weather and also periods of high tide.
x Continue to investigate and address tidal inflow from the 1 st Street basin and also from
the South Harbour area.
x Evaluate and address storm drain cross-connections that may be present in North Harbour basin, as indicated by the City’s previous smoke testing activities. x Evaluate operational activities that may unnecessarily elevate WWTP influent pump station levels, as these levels have a direct and significant impact on system flows during both wet and dry weather.

12 SECTION 2 - DESIGN STANDARDS
2-1.01 DESIGN CRITERIA
A. GENERAL
When the estimated average base wastewater flow for the job exceeds 45,000 GPD, or additional flow carrying capacity may be required for existing or future connections upstream of the job, the Job Engineer shall provide a capacity study report when plans are submitted for preliminary review. The capacity study report shall include a table that presents the proposed pipe diameter, slope, length, Man ning's roughness coefficient, full pipe capacity, design capacity (see below) and the percentage of design capacity utilized for each proposed sewer reach. The percentage of design capacity utilized shall be calculated by dividing the design flow by the design capacity and multiplying by one hundred (100).

B. DESIGN FLOW
Design Flow = (Average base wastewater flow times Peaking Factor) plus (groundwater infiltration factor times acres).

NOTE: Peaking Factor - The peaking factor for the above equation shall be obtained from Figure 2-1, Peak Flow Curve.

Average Base Wastewater - The average base wastewater unit flow factors are presented in the following table:

AVERAGE BASE WASTEWATER UNIT FLOW FACTORS
Land Use Category Units
Unit Flow Factor
(gpd/Unit)
Residential, Single Family Residential Unit 195
Residential, Multiple Family Residential Unit 105
Commercial, Industrial, 1,000 square feet 100
Institutional (Government,
Schools, Churches, etc.)
Groundwater Infiltration (GWI) - The GWI rate for use in the above “Design Flow” equation shall be 170gpd/acre, unless the City of Richmond provides the Job Engineer with an area-specific rate. This rate is an average for summertime GWI following wet weather seasons with higher-than-average rainfall in sewers constructed in the City of Richmond after 1985.

13 C. DESIGN CRITERIA –
Gravity sewers within the City of Richmond shall be designed in accordance with the following design criteria.

1. Design Capacity - Main and trunk sewers shall be designated on the following basis: (See Figure 2 -1).

FIGURE 2-1 – PEAK FLOW CURVE

BWF P e a k in g Facto r (P F )

4.5 4.0

5.0 3.5

3.0 2.5

14 a. For sewers eight (8) and ten (10) inches in diameter, design capacity shall be based on pipes flowing two-thirds full (d/D < or = 0.67). b. For sewers twelve (12) inches and larger in diameter, design capacity shall be based on pipes flowing full without surcharging (d/D < or = 1.0).

2. Velocity and Slope - The minimum acceptable slope for sewer pipe is based upon a velocity of three (3) feet per second for main sewers and a velocity of two (2) feet per second for trunk sewers, both when flowing full. The minimum and maximum design flows for each pipe size at the minimum acceptable slope is provided in Section 2-

1.03.A.4. However, the City of Richmond , at its sole discretion, may allow a lesser slope and/or a larger pipe size on a case- by-case basis where the elevation of the existing system constrains the available elevation drop. When the slope of the sewer exceeds twenty percent (20%), ductile iron pipe conforming to the requirements of Section 4-1.32 Ductile
Iron Pipe of these Specifications shall be used.

3. Pipe Diameter - Diameter of gravity sewers sh all be determined by Manning's pipe friction formula, using a roughness coefficient, "n," of 0.013 or the pipe manufacturer's recommendation, whichever is greater.

4. Pipe Cover and Clearance - Minimum pipe covers and clearance, as specified in Section 2-1.03C, shall be maintained in the design of sanitary sewers. If certain conditions exist which make it impractical to meet the minimum cover and clearance requirements, the conditions and locations sha ll be specifically noted on the sewer profile on the Plans. Special Approval is required for each location where pipe cover or clearances are proposed to be less than the minimums specified. Special pipe, bedding, and/or backfill shall be as directed by.

D. Individual Lot Pumping Systems will be allowed only in cases where no feasible gravity sewering alternative exists. If a sewage pumping system is proposed, the Contractor shall comply with the requirements of Section 4-1.28 of these Specifications. 2-1.02 HILLSIDE AND CREEK AREA
A. The Job Engineer shall submit a geotechnical report prepared by a registered Geotechnical Engineer or a Civil Engineer practicing in Geotechnical Engineering whenever:

1. Sewers are proposed to be installed in easement locations where the existing or proposed cross - slope grade exceeds twenty-five percent (25%).

2. Sewers are proposed to be installed within twenty -five (25) feet of the top of a creek bank or fifty (50) feet of the centerline (flowline) of a creek.

3. Sewers are proposed to be insta lled in historical slide locations or within the area of influence of a potentially unstable hillside.

B. The geotechnical report shall address the following:

1. Geological setting, general soils and bedrock conditions along the proposed sewer alignment, and recommended setbacks from slides and creeks.

2. Slope instability or other geotechnical hazards in the vicinity of the proposed sewer alignment.

3. Potential groundwater issues.

15 4. The effect of trenching and sewer installation on slope stability

5. Recommended requir ements for trenching, bedding, backfill, or special supports that may be recommended.

6. Erosion potential of soils around sewer near water courses.

7. Recommended corrective work if geotechnical hazards are identified.

C. Installation of sewers in unrepaired slide areas will not be allowed.

1. If an acceptable gravity route is feasible around an unrepaired slide, the sewer must be installed around the slide.

2. If the only feasible gravity route is through a slide area, a complete study of the slide must be made by a Geotechnical Engineer. The Geotechnical Engineer shall propose a slide repair acceptable to the City of Richmond.

3. If a satisfactory gravity sewering alternative does not exist, an alternative utilizing sewage pumping individual may be considered.

D. Sewers shall not be located in creek beds or at the bottom of swales.

E. If it is not feasible to locate gravity sewers on the downslope side of homes while maintaining a safe distance from drainage ways, an alternative utilizing sewage pumping shall be consider ed.

F. Sewer crossings at creeks or swales shall be as nearly perpendicular to the centerline (flowline) of the drainage way as feasible, and in no case at an angle less than forty -five (45) degrees to the centerline (flowline) of the creek or swale.

1. The n eed for bank and bottom protection shall be evaluated by a Geotechnical Engineer and recommended protection shall be installed in the drainage way as part of the crossing installation.

2. The Job Engineer shall pay particular attention to designing adequate s upport foundations and protection for the foundation.

G. The following design standards shall be used by the Job Engineer when designing sewers in hillside and/or creek areas.

1. Sewers to be installed in easements and private streets which are located in hillside and/or creek areas shall be restrained joint ductile iron pipe when the soil in which the sewer will be installed is fine grained, such as clay.

2. Pipe material other than ductile iron may be used for sewers to be installed in easements and private streets which are located in hillside and/or creek areas when the soil in which the sewer will be located is coarse grained (including unfractured bedrock).

3. Pipe material other than ductile iron may be used for sewers to be installed in public streets which are located in hillside and/or creek areas.

4. If groundwater is present in the trench area, sewers shall be ductile iron (no bedding) regardless of the type of soil.

16 5. Subdrains may be installed to convey underground water from its source to a storm drain or channel. These subdrains must be maintained perpetually by a permanent entity other than the City of Richmond.

6. For sewers proposed parallel to existing swales or creeks, the sewer shall be located at least fifty (50) feet from the centerline (flowline) of th e creek or swale, and at least twenty -five (25) feet from the top of the bank if the bank is defined, to minimize the potential slope failure in the vicinity of the sewer resulting from undercutting at the toe. A Geotechnical Engineer shall review the proposed alignment and furnish recommendations regarding long- term erosion and slope stability potential.

7. Manholes to be installed at creek crossings shall be located at least fifty (50) feet from the center line of the creek, and at least twenty-five (25) feet from the top of the creek bank if the creek bank is defined.
