RIVERSIDE PARK REGENRATION
Specification No.24-05
THIS AGREEMENT, made this ______ day of ___________________, 20____, by and between the City of Ukiah, Mendocino County, California, hereinafter called the City and _______________________ hereinafter called the Contractor,
WITNESSETH:
WHEREAS, the City has caused to be prepared in accordance with law, specifications, drawings and other contract documents for the work herein described and shown and has approved and adopted these contract documents, specifications and drawings and has caused to be published in the manner and for the time required by law a notice to bidders inviting sealed proposals for doing the work in accordance with the terms of this contract and
WHEREAS, the Contractor, in response to the notice to bidders, has submitted to the City a sealed proposal accompanied by a proposal guaranty in an amount of not less than 10 percent of the bid price for the construction of the proposed work in accordance with the terms of this contract and WHEREAS, the City, in the manner prescribed by law, has publicly opened, examined and canvassed the proposals submitted and as a result has determined and declared the Contractor to be the lowest and best regular responsible bidder for the work and for the sums named in the proposal, NOW, THEREFORE, THIS AGREEMENT WITNESSETH:
Article 1. Work to be Done and Contract Days Allowed.
That the Contractor shall provide all necessary machinery, tools, apparatus and other means of construction; shall furnish all materials, superintendence, overhead, expenses, all labor and expenses of whatever nature necessary for completion of the work in conformity with the Special Provisions and other contract documents hereto attached and according to such instructions as may be given by the Engineer. The Contractor shall complete the work within 180 WORKING days. Contract days shall be counted starting with the 10th day following receipt of notice that the contract has been executed by the City. Contractor, at his or her option, may begin work prior to start of counting contract days, however, in no event shall the Contractor start work without giving notification to the Engineer at least 72 hours prior to the start of work, without obtaining an encroachment permit from the City, or without having submitted certificates of insurance that have been accepted and approved by the Engineer.
Article II. Contract Prices.
That the City shall pay the Contractor the prices stated in the proposal submitted by the Contractor, for complete performance of the contract by the Contractor. The Contractor hereby agrees to accept the prices as full compensation for all material and appliances necessary to the work, for all labor and use of tools and other implements necessary to execute the work contemplated in this contract; for all loss or damage arising out of
RIVERSIDE PARK REGENERATION 89 Spec No.24-05
REFLECTING ADDENDUM 3
the nature of the work or from the action of the elements, or from any unforeseen obstructions or difficulties which may be encountered in the prosecution of the work; for all risks of every description connected therewith; for all expenses of the work, as herein specified; for all liability and other insurance, for all overhead and other expenses incident to the work; all according to the Contract Drawings, the Special Provisions, the Details, the instructions and the requirements of the City.
Article III. Labor Discrimination.
Attention is directed to Section 1735 of the Labor Code, which reads as follows:
"No discrimination shall be made in the employment of persons upon public works because of the race, color, national origin or ancestry, or religion of such persons and every contractor for public works violating this section is subject to all the penalties imposed for a violation of this chapter." In connection with the performance of work under this contract, the Contractor agrees as follows:
(a) The Contractor will not willfully discriminate against any employee or an applicant for employment because of race, color, religion, ancestry, or national origin. The Contractor will take affirmative action to ensure that applicants are employed and that employees are treated during employment without regard to their race, color, religion, ancestry, or national origin. Such action shall include, but not be limited to, the following: employment, upgrading, demotion or transfer; recruitment or recruitment advertising; layoff or termination; rates of pay or other forms of compensation; and selection for training, including apprenticeship. The Contractor agrees to post in conspicuous places, available to employees and applicants for employment, notices to be provided by the awarding authority setting forth the provisions of this Fair Employment Practice section. (b) The Contractor will send to each labor union or representative of workers with which he or she has a collective bargaining agreement or other contract or understanding, a notice, to be provided by the awarding authority, advising the said labor union or worker's representative of the Contractor's commitments under this section, to employees and applicants for employment. (c) The Contractor will permit access to his or her records of employment, employment advertisements, application forms and other pertinent data and records by the Fair Employment Practices Commission, City of Ukiah or any other appropriate agency of the State of California designated by the awarding authority, for the purposes of investigation to ascertain compliance with the Fair Employment Practices section of this contract. (d) A finding of willful violation of the Fair Employment Practices section of this Contract or of the Fair Employment Practices Act shall be regarded by the awarding authority as a basis for determining the Contractor to be not a "responsible bidder" as to future contracts for which such Contractor may submit bids, for revoking the Contractor's pre-qualification rating, if any and for refusing to establish, reestablish or renew a pre-qualification rating for the Contractor.
The City of Ukiah shall deem a finding of willful receipt of written notice from the Fair Employment Practices Act to have occurred upon that it has investigated and determined that the Contractor has violated the Fair Employment Practices Act and has issued an order under Labor Code Section 1426 or obtained an injunction under Labor Code Section 1429.
Upon receipt of such written notice from the Fair Employment Practices Commission, the City shall notify the Contractor that unless he or she demonstrates to the satisfaction of the awarding authority within a stated period that the violation has been corrected, his or her pre-qualification rating will be revoked at the expiration of such period. (e) The Contractor agrees that should the City determine that the Contractor has not complied with the Fair Employment Practices section of this Contract, then pursuant to Labor Code Section 1735 and 1775 the Contractor shall, as a penalty to the City, forfeit for each calendar day or portion thereof,
RIVERSIDE PARK REGENERATION 90 Spec No.24-05
REFLECTING ADDENDUM 3
for each person who was denied employment as a result of such non-compliance, the penalties provided in the Labor Code for violation of prevailing wage rates. Such monies may be recovered from the Contractor. The City may deduct any such damages from any monies due the Contractor. (f) Nothing contained in this Fair Employment Practices section shall be construed in any manner of fashion so as to prevent the City or the State of California from pursuing any other remedies that may be available at law.
(g) Prior to awarding the Contract, the Contractor shall certify to the awarding authority that he or she has or will meet the following standards for affirmative compliance, which shall be evaluated in each case by the awarding authority:
(1) The Contractor shall provide evidence, as required by the City that he or she has notified all supervisors, foremen and other personnel officers in writing of the content of the anti-discrimination clause and their responsibilities under it.
(2) The Contractor shall provide evidence, as required by the City, that he or she has notified all sources of employees’ referrals (including unions, employment agencies, advertisements, Department of Employment) of the content of the anti-discrimination clause. (3) The Contractor shall file a basic compliance report, as required by the City. Willfully false statements made in such reports shall be punishable as provided by law. The compliance report shall also spell out the sources of the work force and who has the responsibility for determining whom to hire, or whether or not to hire.
(4) Personally, or through his or her representatives, the Contractor shall, through negotiations with the unions with whom he or she has agreements, attempt to develop an agreement which will:
a. Spell out responsibilities for nondiscrimination in hiring, referral, upgrading and training. b. Otherwise implement an affirmative anti-discrimination program in terms of the unions' specific areas of skill and geography to the end that qualified minority workers will be available and given and equal opportunity for employment.
(5) The Contractor shall notify the City of opposition to the anti-discrimination clause by individuals, firms or organizations during the period of its pre-qualification. (h) The Contractor will include the provisions of the foregoing paragraphs 1 through 5 in every first tier subcontract so that such provisions will be binding upon each such subcontractor. (i) The "Fair Employment Practices Certification" must be completed and signed prior to the time of submitting the bid.

Section 1 SWPPP Requirements
1.1 INTRODUCTION
This Stormwater Pollution Prevention Plan (SWPPP) is designed to comply with California’s General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities (2022 CGP), State Water Resources Control Board (State Water Board) Order No. 2022-0057-DWQ (NPDES No. CAS000002) (Appendix S). This SWPPP has been prepared following the 2022 CGP SWPPP Template for Traditional Projects provided in the California Stormwater Quality Association (CASQA) Stormwater Best Management Practice (BMP) Handbook: Construction (CASQA 2023).
This project is considered a traditional construction project.
In accordance with the 2022 CGP, Section IV.O, this SWPPP is designed to address the following:
• Identification of all pollutants, their sources, and control mechanisms, including sources of sediment associated with all construction activities (e.g., sediment, paint, cement, stucco, cleaners, site erosion);
• Pollutant source assessments, including a list of potential pollutant sources and identification of site areas where additional BMPs are necessary to reduce or prevent pollutants in stormwater and authorized non-stormwater discharges, per the minimum requirements when developing the pollutant source assessment; • Description of site-specific BMPs implemented to reduce or eliminate stormwater pollution;
• Where not otherwise required to be under a Regional Water Quality Control Board (Regional Water Board) permit, all non-stormwater discharges are identified and either eliminated, controlled, or treated;
• Site BMPs are effective and result in the reduction or elimination of pollutants in stormwater discharges and authorized non-stormwater discharges from construction activity to the Best Available Technology/Best Control Technology (BAT/BCT) standard; and;
• Stabilization BMPs are installed to reduce or eliminate pollutants after construction is completed are effective and maintained; and
• Calculations and design details, as well as BMP controls, are complete and correct.
The Riverside Park Regeneration Project (Project or Site) comprises approximately 8.6 acres, of which 6.52 will be disturbed. The Project is located at 1281 E Gobbi Street in Ukiah, California.
The property is owned by the City of Ukiah and is being developed by the City as a park. The project’s location is shown on the Site Maps in Appendix A.
1.2 PERMIT REGISTRATION DOCUMENTS

implemented immediately following identification of the discharge or written notice of noncompliance from the Regional Board. Discharges and corrective actions must be documented and include the following items:
• The date, time, location, nature of operation, and type of unauthorized discharge; • The cause or nature of the notice or order;
• The BMPs deployed before the discharge event, or prior to receiving notice or order; and • The date of deployment and type of BMPs deployed after the discharge event, or after receiving the notice or order, including additional measures installed or planned to reduce or prevent re-occurrence.
Results of (pH and turbidity, etc.) monitoring will be electronically submitted through SMARTS for all field sampling results within 30 days of the completion of the precipitation event or within 10 days if the field sampling results demonstrate the exceedance of the pH and/or turbidity NALs. See Section 7.7.2.7 for additional discussion of the reporting requirements.
Reporting requirements for pH and turbidity Receiving Water Monitoring Triggers are discussed in Section 7.7.2.7.
Results of non-visible pollutant monitoring and corrective actions will be electronically submitted within 30 days after obtaining analytical results or within 10 days if the analytical results demonstrate the exceedance of an applicable TMDL-related NAL or NEL or Basin Plan parameter. See Section 7.7.1.7 for additional discussion of the reporting requirements.
A NAL exceedance report will be prepared when requested, in writing, by the Regional Water Board.
In the event of a TMDL NEL exceedance, by the end of each reporting year the project will submit and certify, in SMARTS, documentation of the site assessment, SWPPP evaluation, and implementation of the corrective actions.
1.7 CHANGES TO PERMIT COVERAGE
The 2022 CGP allows for the reduction or increase of the total acreage covered under the 2022 CGP when: a portion of the project is complete and/or conditions for termination of coverage have been met; when ownership of a portion of the project is purchased by a different entity; or when new acreage is added to the project.
Modified PRDs will be filed electronically through a Change of Information (COI) within 30 days of a reduction or increase in total disturbed area if a change in permit-covered acreage is to be sought. The SWPPP will be modified appropriately and will be logged at the front of the SWPPP. SWPPP Amendments QSD Certifications will be located in Appendix C. COIs submitted electronically via SMARTS can be found in Appendix D.
1.8 NOTICE OF TERMINATION
A Notice of Termination (NOT) must be submitted electronically by the LRP or DAR via SMARTS to terminate coverage under the 2022 CGP.

The Riverside Park Regeneration Project site is Risk Level 2 that will include approximately 6.52 acres of ground disturbance located at 1281 East Gobbi Street in Ukiah, California (see Sheet L0.0 in Appendix A). The project site is located at the eastern end of East Gobbi Street in Riverside Park. The project site is located approximately 200 feet west of the Russian River.
The project is located at latitude 39.143399, and longitude -123.182880.
2.1.2 Existing Conditions
As of the initial date of this SWPPP, the project site is undeveloped with some vegetated areas, some dirt roads, and three debris piles of concrete, asphalt, and street sweepings. Some household debris is also present in scattered locations. Parts of the project site were previously used at different times for sewage treatment ponds, a trap shooting range, and a police shooting range. The sewage treatment ponds and shooting ranges were previously removed by 1978. Soil sampling and analysis was conducted to test for residual contamination; the results of this analysis are in Appendix Q. The results identified one hot spot of soil with lead and pesticides at concentrations above regulatory action levels (see Sheet L1.3 in Appendix A). This hot spot area will be removed and disposed of at an offsite disposal facility permitted to accept the waste.
2.1.3 Existing Drainage
The project site is relatively level and hummocky with three debris piles. The elevation of most the project site ranges from 580 to 585 feet above mean sea level (msl). The two small jurisdictional wetlands shown on Sheet L1.2 are seasonal wetlands likely fed by groundwater or underflow from the river and are as low as 572 feet above msl. The three debris piles shown on Sheet L1.2 rise as high as about 594 feet above msl. Surface drainage at the site is internal and does not directly drain to the Russian River. Stormwater infiltrates into the onsite soil or flows to the internal jurisdictional wetlands. Existing site topography, drainage patterns, and stormwater conveyance systems are shown on Sheet L1.0 in Appendix A.
The project does not directly discharge to any surface water bodies. However, the site is about 200 feet west of the Russian River. This reach of the river is identified as a 303(d) listed water body: Russian River HU, Upper Russian River HA, Ukiah HSA. The water quality impairments (303 (d) list and TMDLs identified in the 2022 CGP Table H-1 for the receiving waters are identified in Table 2-1.

2.1.4 Geology and Groundwater
The site is underlain by a heterogenous mix of mostly gravel, sand, and silt from previous poorly-documented fill events. Groundwater occurs beneath the site at a few feet below grade, and is likely a combination of groundwater migrating from upland areas from the west and underflow from the Russian River. The groundwater gradient is unknown but assumed to be southerly since the Russian River also flows south.
2.1.5 Project Description
Project grading will occur on approximately 6.52 acres of the project site, which comprises approximately 76 percent of the total area. The limits of grading are shown on Sheet L1.3 through L1.6 in Appendix A. Grading will include both cut and fill activities. About 1,140 cubic yards of clay soil would be imported to the site because the existing soils are of poor quality for vegetation. Approximately 90 cubic yards of decomposed granite would be imported and installed on the walking pathways shown on Sheet L2.0 in Appendix A.
For export, about 228 cubic yards of contaminated soil will be disposed of at an offsite facility permitted to accept the waste (see Sheet L1.3 in Appendix A). The soil sampling report in Appendix Q provides further information regarding the contaminated soil. Approximately 2,260 cubic yards of existing waste piles (see Sheet L1.2 in Appendix A) consisting of concrete, relic asphalt, and other debris will be removed and recycled to the extent possible at a facility permitted to accept the material. Approximately 1,002 cubic yards of selected non-native invasive plant species such as Himalayan blackberry and other exotic species would be removed using hand tools and light equipment such as a weed whacker. The non-native vegetation will be sent to an offsite green waste facility.
Construction activities will be conducted in phases: (1) removal of contaminated soil and debris piles, (2) grading to final topography and installation of public access improvements as shown on Sheet L2.0 in Appendix A, and (3) revegetation.
2.1.6 Developed Condition
Post-construction surface drainage will be internal with stormwater infiltrating into the subsurface or flowing to the two jurisdictional wetlands, as it does now. Post-construction drainage patterns and conveyance systems are presented on Sheets L2.0 and L2.1 in Appendix A.

2.2 PERMITS AND GOVERNING DOCUMENTS
In addition to the 2022 CGP, the following documents have been taken into account while preparing this SWPPP:
• Regional Water Board Basin Plan requirements
• Contract Documents
• County of Mendocino: Flood Hazard Zone Development Permit
2.3 STORMWATER RUN-ON FROM OFFSITE AREAS
Run-on to the site could be generated by overland flow during storm events from offsite areas west of the project site. However, the areas west of the project site are vineyards that control erosion on their site and run-off from the vineyards would be negligible, if any. Nonetheless and as required by the 2022 CGP, silt fences will be installed along the entire border of the project site to manage run-on, if any, as shown on Sheet L1.0 in Appendix A.

2.4 FINDINGS OF THE CONSTRUCTION SITE SEDIMENT AND
RECEIVING WATER RISK DETERMINATION
A construction site risk assessment has been performed for the project and the resultant risk level is Risk Level 2.
The risk level was determined through the use of the R-value determined from EPA’s Rainfall Erosivity Factor Calculator for Small Construction Sites at: https://lew.epa.gov/ in accordance with the State Water Board Guidance for multi-year projects at:
https://www.waterboards.ca.gov/water_issues/programs/stormwater/smarts/construction/do cs/rfactor_guide.pdf, and K and LS using the SWRCB GIS file at:
ftp://swrcb2a.waterboards.ca.gov/pub/swrcb/dwq/cgp/Risk/. The risk level is based on project duration, location, proximity to impaired receiving waters, and soil conditions. A copy of the Risk Level determination with the PRDs is included in Appendix B.
Table 2-3 and Table 2-4 summarize the sediment and receiving water risk factors and document the sources of information used to derive the factors.

Risk Level 2 sites are subject to both the narrative effluent limitations and numeric action limitations (NALs). The narrative effluent limitations require stormwater discharges associated with construction activity to minimize or prevent pollutants in stormwater and authorized nonstormwater through the use of controls, structures and best management practices (BMPs).
Discharges from Risk Level 2 site are subject to NALs for pH and turbidity shown in Table 2-5.
This SWPPP has been prepared to address Risk Level 2 requirements (2022 CGP Attachment D).

2.5 CONSTRUCTION SCHEDULE
The site sediment risk was determined based on construction taking place between June 1, 2024, and October 14, 2024. Modification or extension of the schedule (start and end dates) may affect risk determination and permit requirements. The LRP shall contact the QSD if the schedule changes during construction to address potential impact to the SWPPP. The estimated schedule for planned work can be found in Appendix E.

2.6 POTENTIAL CONSTRUCTION ACTIVITY AND POLLUTANT
SOURCES
Appendix F includes a list of construction activities and associated materials that are anticipated to be used onsite as well as the pollutant source assessment form that was completed for the project. These activities and associated materials will or could potentially contribute pollutants, other than sediment, to stormwater runoff.
A list of construction activities and associated materials that are anticipated to be used on site is provided below. These activities and associated materials could potentially contribute pollutants, other than sediment, to stormwater runoff:
• Excavation and removal of three concrete debris piles and one contaminated soil hot spot (sediment, lead, and residual pesticides)
• Grading and excavation to rework topography and install irrigation system (sediment) • Pouring of concrete pad for kiosk (pH)
• Equipment leaks (fuel, oil, lubricants, coolant)
• General construction waste and litter
The anticipated activities and associated pollutants were used in Section 3 to select the BMPs for the project. Locations of anticipated pollutants and associated BMPs are shown on Sheets L1.0 and L1.1 (BMPs) and L1.3 (contaminants) in Appendix A.
Additionally, proper measures will be taken to ensure that trench spoils or any other soils disturbed during construction activities that are contaminated are not discharged with stormwater or non-stormwater discharges into storm drains or water bodies (except pursuant to a separate NPDES Permit). If contaminated soil is found on site, and the responsible party cannot be identified or fails to take action, the soil will be sampled to determine proper handling and protect public safety. The appropriate local, State, and federal agencies along with the appropriate Regional Water Board will be notified when contaminated soils are observed.
For sampling requirements for non-visible pollutants associated with construction activity, please refer to Section 7.7.1. For a full and complete list of onsite pollutants, refer to the Safety Data Sheets (SDS), which are retained onsite at the construction trailer or are available electronically at the site.
2.7 TMDL REQUIREMENTS
The Russian River is not listed in the 2022 CGP Appendix H. Although the Ukiah reach of the Russian River is a 303(d) listed water body identified for aluminum, manganese, sediment, and temperature, TMDLs have not yet been established for these parameters in this reach of the river.
2.8 IDENTIFICATION OF NON-STORMWATER DISCHARGES
Non-stormwater discharges into storm drainage systems or waterways, which are not authorized under the 2022 CGP and listed in the SWPPP, or authorized under a separate NPDES permit, are prohibited. There are no authorized non-stormwater discharges from this site. Steps will be taken, including the implementation of appropriate BMPs, to ensure that unauthorized discharges are eliminated, controlled, disposed, or treated on-site.
Discharges of construction materials and wastes, such as fuel or paint, resulting from dumping, spills, or direct contact with rainwater or stormwater runoff, are also prohibited.

3.2 EROSION AND SEDIMENT CONTROL
Erosion and sediment controls are required by the 2022 CGP to provide effective reduction or elimination of sediment related pollutants in stormwater discharges and authorized nonstormwater discharges from the Site. Applicable BMPs are identified in this section for erosion control, sediment control, tracking control, and wind erosion control.
3.2.1 Erosion Control
Erosion control, also referred to as soil stabilization, consists of source control measures that are designed to prevent soil particles from detaching and becoming transported in stormwater runoff. Erosion control BMPs protect the soil surface by covering and/or binding soil particles.
This construction project will implement the following practices to provide effective temporary and final erosion control during construction:
1. Preserve existing vegetation where required and when feasible.
2. The area of soil disturbing operations shall be controlled such that the Contractor is able to implement erosion control BMPs quickly and effectively.
3. Stabilize non-active areas within 14 days of cessation of construction activities or sooner if stipulated by local requirements.
4. Control erosion in concentrated flow paths by applying erosion control blankets, check dams, erosion control seeding, or alternate methods.
5. Prior to the completion of construction, apply permanent erosion control to remaining disturbed soil areas.
Sufficient erosion control materials shall be maintained onsite to allow implementation in conformance with this SWPPP.
The following erosion control BMP selection table, Table 3-2 indicates the BMPs that will be implemented to control erosion on the construction site. Fact Sheets for temporary erosion control BMPs are provided in Appendix G.
These temporary erosion control BMPs shall be implemented in conformance with the following guidelines and as outlined in the BMP Factsheets provided in Appendix G. If there is a conflict between documents, the Site Map will prevail over narrative in the body of the SWPPP or guidance in the BMP Fact Sheets. Site specific details in the Site Map prevail over standard

Soil Preparation-Roughening
The three piles of concrete debris shown on Sheet L1.2 will be removed and will be recycled or disposed of at an offsite facility permitted to accept the materials. The one contaminated soil hot spot shown on Sheet L1.3 will be removed and will be disposed of at an offsite facility permitted to accept the materials.
The topography of the site will be graded to flatten the existing hummocky nature, as shown on Sheet L1.3. The two jurisdictional features (i.e., seasonal wetlands) will be cordoned off with silt fencing and will not be disturbed.
Following most of the debris and vegetation removal, rough grading would be implemented within approximately 3.39 acres of the site, including site recontouring to remove relic berms and realign site drainage. Some of the debris removal would need to occur following rough grading necessary to facilitate the removal. Approximately 0.42 acres of fine grading would occur in the upper terrace to redirect drainage away from the adjacent vineyard located to the west. As depicted on Sheet L1.3 n Appendix A, a series of berms and basins would be reconstructed on the site, designed to allow for seasonal off-channel habitat. To facilitate the reestablishment of seasonal wetlands on site, the project will place and compact a 2-inch base layer in re-contoured basins (in and below the 587 elevation contour). As the existing soils are degraded and do not support wetland vegetation, approximately 1,140 cubic yards of clay soil would be imported for this purpose. The site would be planted with ecologically appropriate wetland vegetation (as shown on Sheets L3.0 and L3.1 in Appendix A), with temporary irrigation to establish plantings (as shown on Sheets L4.0, L4.1, and L4.2 in Appendix A).
Inert soil moved during grading would be redistributed onsite at a location southeast of the park’s main parking lot (and south of the BMX track), which currently is used as overflow parking. Disturbed soils throughout the site would be stabilized and reseeded with ecologically appropriate grasses.
3.2.2 Sediment Controls
Sediment controls are temporary or permanent structural measures that are intended to complement the selected erosion control measures and reduce sediment discharges from active construction areas. Sediment controls are designed to intercept and settle out soil particles that have been detached and transported by the force of water.
The following sediment control BMP selection table indicates the BMPs that will be implemented to control sediment on the construction site. Fact Sheets for temporary sediment control BMPs are provided in Appendix G.
These temporary sediment control BMPs will be implemented in conformance with the following guidelines and in accordance with the BMP Fact Sheets provided in Appendix G. If there is a conflict between documents, the Site Map will prevail over narrative in the body of the SWPPP or guidance in the BMP Fact Sheets. Site specific details in the Site Map prevail over standard details included in the Site Map. The narrative in the body of the SWPPP prevails over guidance in the BMP Fact Sheets.

3.3.2 Materials Management and Waste Management
Materials management control practices consist of implementing procedural and structural BMPs for handling, storing, and using construction materials to prevent the release of those materials into stormwater discharges. The amount and type of construction materials to be utilized at the Site will depend upon the type of construction and the length of the construction period. The materials may be used continuously, such as fuel for vehicles and equipment, or the materials may be used for a discrete period, such as soil binders for temporary stabilization.
Waste management consists of implementing procedural and structural BMPs for handling, storing, and ensuring proper disposal of wastes to prevent the release of those wastes into stormwater discharges.
Materials and waste management pollution control BMPs will be implemented to minimize stormwater contact with construction materials, wastes, and service areas; and to prevent materials and wastes from being discharged offsite. The primary mechanisms for stormwater contact that shall be addressed include:
• Direct contact with precipitation
• Contact with stormwater runon and runoff
A list of construction activities is provided in Section 2.6. The following Materials and Waste Management BMP selection table, Table 3-5, indicates the BMPs that shall be implemented to

3.5 POST CONSTRUCTION STORMWATER MANAGEMENT MEASURES
Post construction BMPs are permanent measures installed during construction, designed to reduce or eliminate pollutant discharges from the site after construction is completed.
This site is subject to the post-construction requirements of an existing NPDES Phase I or Phase II MS4. ☐ Yes ☒ No
The following source control, site design, and treatment control post-construction BMPs to comply with 2022 CGP Section IV.N.3 have been identified for the site.
The Project includes site recontouring and revegetation with native plants to create about six acres of varied-elevation seasonal floodplain wetlands for storm water and floodwater retention, bio-infiltration, groundwater recharge, and native habitat. An earthen berm would be constructed to enhance wetlands, and new native wetland plantings would be installed. In addition, transitional planting and upland area planting with native trees, shrubs, grasses and annual plants would enhance upland areas. The Project’s upland area plantings are designed to incorporate ecologically-appropriate riparian plants, native to the local region of the Russian River, complying with the California Department of Water Resources (DWR) Model Water Efficient Landscape Ordinance (MWELO).
The Project would implement soil restoration to improve soil moisture retention and microbial balance and provide the essential foundation for restoring the site’s plant communities. Clay soil would be imported for this purpose, described in Section 2.1.5. This portion of the project would also focus on expanding the edge of the riparian forest and restoring site grasslands. The proposed planting plan for this restoration is depicted on Sheets L3.0 and L3.1 in Appendix A.
The proposed irrigation plan is depicted on Sheets 4.0, 4.1, and 4.2.
Completion of the planting and irrigation system would control post construction runoff through improved evapotranspiration by the improved vegetation, improved retention of stormwater for infiltration, and maintaining drainage internal to the project site through infiltration and drainage to the two seasonal (jurisdictional) wetlands internal to the project site.
A plan for the post construction funding and maintenance of these BMPs has been developed to address at minimum five years following construction. Through various partnerships with the Mendocino RCD, Peregrine Audubon, the Sanhedrin Chapter of the California Native Plant Society, the City will conduct ongoing management of the site to include community park patrol, bird walks, invasive plant removal, native plant maintenance, and site monitoring. The post construction plan described above will be funded and maintained as described in the Operations and Maintenance Plan that will be uploaded with the Notice of Termination.
CASQA Traditional SWPPP Template 4-1 March 2024

Section 4 BMP Inspection and Maintenance
4.1 BMP INSPECTION AND MAINTENANCE
The 2022 CGP requires routine weekly inspections of BMPs, along with inspections before, during, and after qualifying precipitation events. A BMP inspection checklist must be filled out for inspections and maintained on-site with the SWPPP. The inspection checklist must include the necessary information covered in Section 7.6. A blank BMP Inspection Form can be found in Appendix H. Completed forms will be kept in Appendix N.
Maintenance, repair, or design and implementation of new BMPs alternatives will be begin withing 72 hours of the identification of failures or other shortcomings. Corrections will be completed as soon as possible, prior to the next forecasted precipitation event (2022 CGP Appendix D Section II.J).
The QSP will verify that all BMP maintenance and repairs were appropriately implemented during the next visual inspection following completion.
The QSP may delegate BMP maintenance and repair verification to an appropriately trained QSP Delegate.
Specific details for maintenance, inspection, and repair of Construction Site BMPs can be found in the BMP Factsheets in Appendix G.

Section 7 Construction Site Monitoring Program
7.1 Purpose
This Construction Site Monitoring Program was developed to address the following objectives:
1. To demonstrate that the site is in compliance with the Discharge Prohibitions and Numeric Action Levels (NALs);
2. To determine whether non-visible pollutants discharged from the construction site and are causing or contributing to exceedances of water quality objectives;
3. To determine whether immediate corrective actions, additional BMP implementation, or SWPPP revisions are necessary to reduce pollutants in stormwater discharges and authorized non-stormwater discharges;
4. To determine whether BMPs included in the SWPPP are effective in preventing or reducing pollutants in stormwater discharges and authorized non-stormwater discharges.
7.2 Applicability of Permit Requirements
This project has been determined to be a Risk Level 2 project. The 2022 CGP identifies the following types of monitoring as being applicable for a Risk Level 2 project.
Risk Level 2
• Visual inspections of BMPs;
• Visual monitoring of the site related to qualifying precipitation events; • Visual monitoring of the site for non-stormwater discharges; • Sampling and analysis of construction site runoff, if any, for pH and turbidity; • Sampling and analysis of construction site runoff, if any, for non-visible pollutants identified during the pollutant source assessments when applicable; and • Sampling and analysis of construction site runoff, if any, as required by the Regional Water Board when applicable.
7.3. Weather and Precipitation Event Tracking
Visual monitoring and inspections requirements of the 2022 CGP are triggered by a Qualifying Precipitation Event. The 2022 CGP defines a Qualifying Precipitation Event as any weather pattern that is forecast to have a 50 percent or greater Probability of Precipitation (PoP) and a Quantitative Precipitation Forecast (QPF) of 0.5 inches or more within a 24-hour period. The event begins with the 24-hour period when 0.5 inches has been forecast and continues on subsequent 24-hour periods when 0.25 inches of precipitation or more is forecast.
7.3.1 Weather Tracking
The QSP should daily consult the National Oceanographic and Atmospheric Administration (NOAA) for the Forecast Weather Table Interface. These forecasts can be obtained at http://forecast.weather.gov. Weather reports should be printed and maintained with the SWPPP in Appendix M. Record the date and time the forecast was printed.
CASQA Traditional SWPPP Template 7-2 March 2024
for the 2022 CGP
7.4 Monitoring Locations
The project site drains internally and does not directly drain to the Russian River. In the unlikely event that drainage from the construction site is discovered, monitoring locations will be selected based on the location of the drainage.
Whenever changes in the construction site might affect the appropriateness of sampling locations, the sampling locations shall be revised accordingly. All such revisions shall be implemented as soon as feasible and the SWPPP amended. Temporary changes that result in a one-time additional sampling location do not require a SWPPP amendment.
7.5 Safety and Monitoring Exemptions
Safety practices for sample collection will be in accordance with the [ENTER TITLE AND PUBLICATION DATE OF CONTRACTOR’S HEALTH AND SAFETY PLAN FOR THE PROJECT OR PROVIDE SPECIFIC REQUIREMENTS IN THIS SECTION]. A summary of the safety requirements that apply to sampling personnel is provided below. • List or state none [To be provided by contractor]
This project is not required to collect samples or conduct visual observations (inspections) under the following conditions (see Section III.B of the 2022 CGP):
• During dangerous weather conditions such as electrical storms, flooding, and high winds above 40 miles per hour;
• Outside of scheduled site operating hours; or
• When the site is not accessible to personnel. Scheduled site business hours are: 7 a.m. to 6 p.m., Monday through Friday.
If monitoring (visual monitoring or sample collection) of the site is unsafe because of the dangerous conditions noted above, then the QSP shall document the conditions for why an exception to performing the monitoring was necessary. The exemption documentation will be filed in Appendix N and must be included in the Annual Report.
7.6 Visual Monitoring
Per Section III.B.2. of Attachment D in the 2022 CGP, “For inactive projects, dischargers may reduce the visual inspection frequency and suspend sampling per Section III.G of the 2022 CGP.
Dischargers shall provide an explanation with supporting information for all missed visual inspections or sampling required by this Attachment, to be included in the Annual Report.” Visual monitoring includes observations and inspections. Inspections of BMPs are required to identify and record BMPs that need maintenance to operate effectively, that have failed, or that could fail to operate as intended. Visual observations of the site are required to observe storm water drainage areas to identify any spills, leaks, or uncontrolled pollutant sources.
Table 7-1 identifies the required frequency of visual observations and inspections. Inspections and observations will be conducted at the locations identified in Section 7.6.3.

7.6.1 Routine Observations and Inspections
Routine site inspections and visual monitoring are necessary to confirm that the project is in compliance with the requirements of the 2022 CGP.
7.6.1.1 Routine BMP Inspections
Inspections of BMPs are conducted to identify and record:
• BMPs that are properly installed;
• BMPs that need maintenance to operate effectively;
• BMPs that have failed; or
• BMPs that could fail to operate as intended.
7.6.1.2 Non-Stormwater Discharge Observations
Each drainage area will be inspected for the presence of or indications of prior unauthorized and authorized non-stormwater discharges. Inspections will record:
• Presence or evidence of any non-stormwater discharge (authorized or unauthorized); • Identification and elimination of unauthorized non-stormwater discharges • Pollutant characteristics (floating and suspended material, sheen, discoloration, turbidity, odor, etc.); and
• Source of discharge.
7.6.2 Qualifying Precipitation Event Triggered Observations and Inspections
Visual observations of the site and inspections of BMPs are required prior to a qualifying precipitation event; following a qualifying precipitation event, and every 24-hour period during a qualifying precipitation event. Pre-Qualifying Precipitation Event inspections will be
CASQA Traditional SWPPP Template 7-4 March 2024
for the 2022 CGP
conducted after consulting NOAA and determining that a precipitation event with a 50 percent or greater PoP and a QPF of 0.5 inches or more precipitation within a 24-hour period has been predicted by the National Weather Service Forecast Office.
7.6.2.1 Visual Observations Prior to a Forecasted Qualifying Precipitation Event Within 72 hours prior to a qualifying precipitation event or up to 120 hours prior if extended forecast precipitation data is available, a stormwater visual monitoring site inspection will include observations of the following locations:
• All stormwater drainage areas to identify leaks, spills, or uncontrolled pollutant sources and when necessary, implement appropriate corrective actions. • All BMPs to identify whether they have been properly implemented per the SWPPP and implement appropriate corrective actions, as necessary. • All stormwater storage and containment areas to detect leaks and check for available capacity to prevent overflow.
The QSP must conduct the inspection prior to the qualifying precipitation event. Consistent with the requirements for a qualifying precipitation event, pre-rain BMP inspections and visual monitoring will be triggered by a NOAA forecast that indicates a 50 percent or greater probability of 0.5 inches of precipitation or more in a 24-hour period in the project area.
7.6.2.2 BMP Inspections During a Qualifying Precipitation Event During an extended qualifying precipitation event BMP inspections will be conducted at least once every 24 hours. Qualifying precipitation events are extended for each subsequent 24- hour period forecast to have at least 0.25 inches of precipitation. The BMP inspections are to identify and record:
• If BMPs were adequately designed, implemented and effective. • BMPs that require repair or replacement due to damage. • Additional BMPs that need to be implemented and revise the SWPPP accordingly.
If the construction site is not accessible during the rain event, the visual inspections shall be performed at all relevant outfalls, discharge points, downstream locations. The inspections should record any projected maintenance activities.
7.6.2.3 Visual Observations Following a Qualifying Precipitation Event Within 96 hours following the end of a qualifying precipitation event a stormwater visual monitoring site inspection is required to observe:
• If BMPs were adequately designed, implemented and effective. • BMPs that require repair or replacement due to damage. • Additional BMPs that need to be implemented and revise the SWPPP accordingly.

7.7 Water Quality Sampling and Analysis
7.7.1 Sampling and Analysis Plan for Non-Visible Pollutants in Stormwater Runoff Discharges
This Sampling and Analysis Plan for Non-Visible Pollutants describes the sampling and analysis strategy and schedule for monitoring non-visible pollutants in stormwater runoff discharges from the project site.
Sampling for non-visible pollutants, including those associated with TMDLs will be conducted when (1) a breach, leakage, malfunction, or spill is observed; and (2) the leak or spill has not been cleaned up prior to the rain event; and (3) there is the potential for discharge of non-visible pollutants to surface waters or drainage system.
CASQA Traditional SWPPP Template 7-6 March 2024
for the 2022 CGP
Table 7-2 summarizes the potential non-visible pollutants identified in the pollutant source assessment in Sections 2.6 and 2.7 and the water quality constituent or indicator for that pollutant.

The project has the potential to receive stormwater run-on from the vineyards located adjacent and west of the project site. The run-on has the potential to contribute non-visible pollutants to stormwater discharges from the project.
7.7.1.1 Sampling Schedule
Samples for the potential non-visible pollutant(s) and a sufficiently large unaffected background sample shall be collected during the first eight hours of discharge from rain events that result in a sufficient discharge for sample collection. Samples shall be collected during the site’s scheduled hours and shall be collected regardless of the time of year and phase of the construction.
Collection of discharge samples for non-visible pollutant monitoring will be triggered only when any of the following conditions are observed during site inspections conducted prior to or during a rain event.
• Materials or wastes containing potential non-visible pollutants are not stored under watertight conditions. Watertight conditions are defined as (1) storage in a watertight container, (2) storage under a watertight roof or within a building, or (3) protected by temporary cover and containment that prevents stormwater contact and runoff from the storage area.
• Materials or wastes containing potential non-visible pollutants are stored under watertight conditions, but (1) a breach, malfunction, leakage, or spill is observed, (2) the leak or spill is not cleaned up prior to the rain event, and (3) there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system. • A construction activity, including but not limited to those in Section 2.6, with the potential to contribute non-visible pollutants (1) was occurring during or within 24 hours prior to the rain event, (2) BMPs were observed to be breached, malfunctioning, or improperly implemented, and (3) there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system.
• Soil amendments that have the potential to change the chemical properties, engineering properties, or erosion resistance of the soil have been applied, and there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system.
CASQA Traditional SWPPP Template 7-7 March 2024
for the 2022 CGP
• Stormwater runoff from an area contaminated by historical usage of the site has been observed to combine with stormwater runoff from the site, and there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system.
7.7.1.2 Sampling Locations
Sampling locations are based on proximity to planned non-visible pollutant storage, occurrence or use, accessibility for sampling, and personnel safety. As previously noted, all drainage is internal to the project site; there is no direct drainage to the Russian River. Sampling locations, if any are needed, will be based on observations of the locations of discharge, if any.
If needed, one sampling location would be at the upstream part of the Russin River just adjacent to the upstream (north) edge of the project site. This location has been identified for the collection of an uncontaminated sample of runoff as a background sample for comparison with the samples being analyzed for non-visible pollutants. This location was selected such that the sample will not have come in contact with the operations, activities, or areas identified in Section 7.7.1 or with disturbed soils areas.

• Evaluating the SWPPP and its implementation to determine whether additional BMPs or SWPPP implementation measures are necessary to reduce or prevent pollutants in all regulated discharges to comply applicable NELs, and
• Certifying and submitting through SMARTS a report of the above site assessment and SWPPP evaluation that:
o Additional BMPs or SWPPP implementation measures have been identified and included in the SWPPP, or
o No additional BMPs or SWPPP implementation measures are required to reduce or prevent pollutants in all regulated discharges to comply with applicable NELs.
7.7.2 Sampling and Analysis Plan for pH and Turbidity in Stormwater Runoff Discharges
Sampling and analysis of runoff for pH and turbidity is required for this Risk Level 2 project, in the event that runoff occurs. This Sampling and Analysis Plan describes the strategy for monitoring turbidity and pH levels of stormwater runoff discharges from the project site and run-on that may contribute to an exceedance of a Numeric Action Level (NAL). Samples for pH and turbidity will be collected at all discharge points where stormwater is discharged off-site.
CASQA Traditional SWPPP Template 7-12 March 2024
for the 2022 CGP
7.7.2.1 Sampling Schedule
Stormwater runoff samples shall be collected for pH and turbidity from each day of a qualifying precipitation event that results in a discharge from the project site, in the event that discharge occurs. One sample from each discharge location will be collected each 24-hour period of active discharge during a qualifying precipitation event. Samples should be representative of the discharge flow and characteristics. Run-on samples shall be collected whenever the QSP identifies that run-on has the potential to contribute to an exceedance of a NAL.
7.7.2.2 Sampling Locations
Sampling locations are based on the site runoff discharge locations and locations where run-on enters the site, accessibility for sampling, and personnel safety. As previously noted, all drainage at the project site is internal; there are no direct discharge locations to the Russian River. Therefore, in the unlikely event of a discharge, pH and turbidity sampling locations, if any are needed, will be based on observations of the locations of run-on and run-off discharge, if any.
7.7.2.3 Monitoring Preparation
Turbidity and pH samples will be collected and analyzed by:
QSP [Name] ☒ Yes ☐ No
QSD Delegate [Name] ☒ Yes ☐ No
An adequate stock of monitoring supplies and equipment for monitoring turbidity and pH will be available on the project site prior to a sampling event. Monitoring supplies and equipment will be stored in a cool temperature environment that will not come into contact with rain or direct sunlight. The QSP or QSP Delegates will be available to collect samples in accordance with the sampling schedule. Supplies maintained at the project site will include, but are not limited to, field meters, extra batteries, clean powder-free nitrile gloves, sample collection equipment, appropriate sample containers, paper towels, personal rain gear, and Effluent Sampling Field Log Sheets and CoC forms provided in Appendix O.
The QSP or QSP Delegates will obtain and maintain the field-testing instruments, as identified in Section 7.7.2.6, for analyzing samples in the field. Field meter instructions are provided in Appendix P.

7.7.7 Sample Collection and Handling
7.7.7.1 Sample Collection
Samples shall be collected at the sampling locations discussed in Sections 7.7.1.2 and 7.7.2.2.
Samples shall be collected, maintained and shipped in accordance with the 2022 CGP Sample Collection and Handling Instructions. Grab samples shall be collected and preserved in accordance with the methods identified in preceding sections. To maintain sample integrity and prevent cross-contamination, sample collection personnel shall follow the protocols below. • Collect samples (for laboratory analysis) in analytical laboratory-provided or specified sample containers;
o Use of any other type of containers could cause sample contamination and may result in NAL exceedances.
• Wear clean, powder-free nitrile gloves when collecting samples; • Change gloves whenever something not known to be clean has been touched; • Change gloves between sampling locations;
• Decontaminate all equipment (e.g., bucket, tubing) prior to sample collection; o using a trisodium phosphate water wash, distilled water rinse, and final rinse with distilled water..
o Dispose of wash and rinse water appropriately (i.e., do not discharge to storm drain or receiving water).
o Do not decontaminate laboratory provided sample containers; • Do not smoke during sampling events;
• Never sample near a running vehicle;
CASQA Traditional SWPPP Template 7-17 March 2024
for the 2022 CGP
• Do not park vehicles in the immediate sample collection area (even non-running vehicles);
• Do not eat or drink during sample collection; and
• Do not breathe, sneeze, or cough in the direction of an open sample container.
The most important aspect of grab sampling is to collect a sample that represents the entire runoff stream. Typically, samples are collected by dipping the collection container in the runoff flow paths and streams as noted below.
i. For small streams and flow paths, simply dip the bottle facing upstream until full. ii. For larger stream that can be safely accessed, collect a sample in the middle of the flow stream by directly dipping the mouth of the bottle. Once again making sure that the opening of the bottle is facing upstream as to avoid any contamination by the sampler. iii. For larger streams that cannot be safely waded, pole-samplers may be needed to safely access the representative flow.
iv. Avoid collecting samples from ponded, sluggish or stagnant water. v. Avoid collecting samples directly downstream from a bridge as the samples can be affected by the bridge structure or runoff from the road surface.
Note, that depending upon the specific analytical test, some containers may contain preservatives. These containers should never be dipped into the stream but filled indirectly from the collection container.
7.7.7.2 Sample Handling
Turbidity and pH measurements must be conducted immediately. Do not store turbidity or pH samples for later measurement.
Samples for laboratory analysis must be handled as follows. Immediately following sample collection:
• Cap sample containers;
• Complete sample container labels;
• Place sealed containers in a re-sealable storage bag; • Place sample containers into an ice-chilled cooler;
• Document sample information on the Effluent Sampling Field Log Sheet (Appendix O); and
• Complete the CoC.
All samples for laboratory analysis must be maintained between 0-6 degrees Celsius during delivery to the laboratory. Samples must be kept on ice, or refrigerated, from sample collection through delivery to the laboratory. Place samples to be shipped inside coolers with ice. Make sure the sample bottles are well packaged to prevent breakage and secure cooler lids with packaging tape.
Ship samples that will be laboratory analyzed to the analytical laboratory right away. Hold times are measured from the time the sample is collected to the time the sample is analyzed. The 2022 CGP requires that samples be received by the analytical laboratory within 48 hours of the physical sampling (unless required sooner by the analytical laboratory to meet all hold times).

7.7.7.3 Sample Documentation Procedures
All original data documented on sample container identification labels, Effluent Sampling Field Log Sheet (Appendix O), and CoCs shall be recorded using waterproof ink. These shall be considered accountable documents. If an error is made on an accountable document, the individual shall make corrections by lining through the error and entering the correct information. The erroneous information shall not be obliterated. All corrections shall be initialed and dated.
Duplicate samples shall be identified consistent with the numbering system for other samples to prevent the laboratory from identifying duplicate samples. Duplicate samples shall be identified in the Effluent Sampling Field Log Sheet.
Sample documentation procedures include the following:
Sample Bottle Identification Labels: Sampling personnel shall attach an identification label to each sample bottle. Sample identification shall uniquely identify each sample location. (These location identifiers should be listed in the tables in the SWPPP.) Field Log Sheets: Sampling personnel shall complete the Effluent Sampling Field Log Sheet and Receiving Water Sampling Field Log Sheet (Appendix O) for each sampling event, as appropriate.
Chain of Custody: Sampling personnel shall complete the CoC for each sampling event for which samples are collected for laboratory analysis. The sampler will sign the CoC (Appendix O) when the sample(s) is turned over to the testing laboratory or courier.
7.8 Active Treatment System Monitoring

Will passive treatment technologies be deployed on the site? ☐ Yes ☒ No
This project does not require a project specific Sampling and Analysis Plan for passive treatment because deployment of passive treatment is not planned.
7.10 Watershed Monitoring Option
This project is not participating in a watershed monitoring option.
7.11 Quality Assurance and Quality Control
An effective Quality Assurance and Quality Control (QA/QC) plan shall be implemented as part of the CSMP to ensure that analytical data can be used with confidence. QA/QC procedures to be initiated include the following:
CASQA Traditional SWPPP Template 7-19 March 2024
for the 2022 CGP
• Field logs;
• Clean sampling techniques;
• CoCs;
• QA/QC Samples, if needed; and
• Data verification.
Each of these procedures is discussed in more detail in the following sections.
7.11.1 Field Logs
The purpose of field logs is to record sampling information and field observations during monitoring that may explain any uncharacteristic analytical results. Sampling information to be included in the field log include the date and time of water quality sample collection, sampling personnel, sample container identification numbers, and types of samples that were collected.
Field observations should be noted in the field log for any abnormalities at the sampling location (color, odor, BMPs, etc.). Field measurements for pH and turbidity should also be recorded in the field log. A Visual Inspection Field Log, an Effluent Sampling Field Log Sheet, [and a Receiving Water Sampling Field Log Sheet] are included in Appendix O.
7.11.2 Clean Sampling Techniques
Clean sampling techniques involve the use of certified clean containers for sample collection and clean powder-free nitrile gloves during sample collection and handling. As discussed in Section 7.7.7, adoption of a clean sampling approach will minimize the chance of field contamination and questionable data results.
7.11.3 Chain of Custody
The sample CoC is an important documentation step that tracks samples from collection through analysis to ensure the validity of the sample. Sample CoC procedures include the following:
• Proper labeling of samples;
• Use of CoC forms for all samples; and
• Prompt sample delivery to the analytical laboratory.
Analytical laboratories usually provide CoC forms to be filled out for sample containers. An example CoC is included in Appendix O.
7.11.4 QA/QC Samples
QA/QC samples provide an indication of the accuracy and precision of the sample collection; sample handling; field measurements; and analytical laboratory methods. The following types of QA/QC will be conducted for this project:
☒ Field Duplicates at a frequency of [5 percent or 1 duplicate minimum per sampling event]
(Required for all sampling plans with field measurements or laboratory analysis) ☐ Equipment Blanks at a frequency of [Insert frequency required by method] (Only needed if the equipment used to collect samples could add the pollutants to sample) ☐ Field Blanks at a frequency of [Insert frequency required by method] (Only required if sampling method calls for field blanks)
CASQA Traditional SWPPP Template 7-20 March 2024
for the 2022 CGP
☐ Travel Blanks at a frequency of [One per sampling event] (Required for sampling plans that include VOC laboratory analysis)
7.11.4.1 Field Duplicates
Field duplicates provide verification of laboratory or field analysis and sample collection.
Duplicate samples shall be collected, handled, and analyzed using the same protocols as primary samples. The sample location where field duplicates are collected shall be randomly selected from the discharge locations. Duplicate samples shall be collected immediately after the primary sample has been collected. Duplicate samples must be collected in the same manner and as close in time as possible to the original sample.
7.11.4.2 Equipment Blanks
Equipment blanks provide verification that equipment has not introduced a pollutant into the sample. Equipment blanks are typically collected when:
• New equipment is used;
• Equipment that has been cleaned after use at a contaminated site; • Equipment that is not dedicated for surface water sampling is used; or • Whenever a new lot of filters is used when sampling metals.
7.11.4.3 Field Blanks
Field blanks assess potential sample contamination levels that occur during field sampling activities. De-ionized water field blanks are taken to the field, transferred to the appropriate container, and treated the same as the corresponding sample type during the course of a sampling event.
7.11.4.4 Travel Blanks
Travel blanks assess the potential for cross-contamination of volatile constituents between sample containers during shipment from the field to the laboratory. De-ionized water blanks are taken along for the trip and held unopened in the same cooler with the VOC samples.
7.11.5 Data Verification
After results are received from the analytical laboratory, the QSP or QSP Delegates shall verify the data to ensure that it is complete, accurate, and the appropriate QA/QC requirements were met. Data must be verified as soon as the data reports are received. Data verification shall include:
• Check the CoC and laboratory reports.
Make sure all requested analyses were performed and all samples are accounted for in the reports.
• Check laboratory reports to make sure hold times were met and that the reporting levels meet or are lower than the reporting levels agreed to in the contract. • Check data for outlier values and follow up with the laboratory.
Occasionally typographical errors, unit reporting errors, or incomplete results are reported and should be easily detected. These errors need to be identified, clarified, and corrected quickly by the laboratory. The QSP or QSP Delegates should especially note data that is an order of magnitude or more different than similar locations or is inconsistent with previous data from the same location.
