Irvine, CA 92606
Attention: Mr. Pat Somerville, P.E.

Subject: Geotechnical Memorandum
Montebello Sewer Program
Montebello, California
Dear Mr. Somerville:

This memorandum presents the findings and conclusions of a geotechnical study conducted by Earth Mechanics, Inc. (EMI) in City of Montebello as part of the Montebello Sewer Program.

The purpose of this geotechnical study was to evaluate the existing site conditions, obtain information on subsurface soils, and develop design and construction recommendations for the proposed improvements to assist Mark Thomas & Company, Inc. (MTC) in preparing the Plans, Specifications, and Estimates (PS&E) for the project.

1.0 Introduction
The City of Montebello proposes to replace multiple sewer lines along the following streets.

Northerly and southerly alleys are located just north and south sides of the W Whittier Boulevard between S Montebello Boulevard and Rio Hondo Channel:
• Palm Place from N Spruce St to a distance of about 330 feet • Northerly Alley between N Montebello Boulevard and N Poplar Avenue for a distance of about 2,600 feet. This alley includes laterals along N Montebello Boulevard, N 6th Street and N 5th Street towards W Whittier Boulevard
• Southerly Alley between S Montebello Boulevard and S Bluff Road for a distance of about 2,300 feet. This alley includes laterals along S Montebello Boulevard, S 7th Street, S 6th Street and S 5th Street towards W Whittier Boulevard
It is our understanding that, after the completion of the installation of sewer lines and backfilling the trench, the existing roadway will be reconstructed with new pavements. The project location is shown in Figure 1.

2.0 Climatic Conditions
The climate of the project region is Mediterranean. The hottest months are July through September with average high temperatures in the high 80’s (°F) and average low temperatures in the mid 60’s (°F). The coolest temperatures occur in the winter months of November through March with

2 the average high temperatures in the high 60’s to mid 70’s (°F) and average low temperatures in the high 40’s to low 50’s (°F).

Annual average precipitation is about 14.8 inches with most of the rain falling in January. Snowfall is not anticipated in the area. Based on the above information, freeze-thaw recommendations are not expected to be required.

Per Caltrans Highway Design Manual (Caltrans, 2023a), the project site is located in the “South Coast” climate region.

3.0 Geotechnical Investigation
A geotechnical field investigation was conducted along the proposed sewer replacement by EMI on September 3, 2024. The field investigation included three hollow-stem auger borings and two hand auger borings. Soil exploration information is summarized in Table 1. The coordinates and elevations were obtained using handheld GPS device. All the boring logs are included in Appendix A. The approximate locations of the borings are shown in Figure 2.

B-5 HA 34.0083 -118.1023 +209.6 +199.6 NE
Notes: HSA = Hollow-Stem Auger, HA = Hand Auger; NE = Not Encountered.

The hollow-stem auger borings were drilled using track-mounted drill rig (CME 75) equipped with 8-inch diameter hollow-stem augers. The hand auger borings were drilled using a 3-inch diameter stainless steel hand auger. Subsurface soils and conditions were logged, and samples of soils were collected for laboratory testing. Smaller disturbed and relatively undisturbed soil samples were collected from borings generally at 2.5-foot intervals using the Modified California Drive (MCD) sampler. The MCD sampler is lined with a series of 1-inch tall brass rings with an inside diameter of 2.4 inches. Bulk samples were also collected from the borings.

4.0 Soil Laboratory Testing and Results
Soil samples, considered representative of the subsurface conditions, were tested to obtain or derive relevant physical and engineering properties. The type of laboratory tests include: moisture content, dry density, percentage passing the No. 200 sieve, Atterberg Limits, direct shear, UU triaxial, compaction, and R-value. The laboratory soil tests were conducted in general accordance with California Test (CT) methods or American Society for Testing and Materials (ASTM) standards. The laboratory test results of the near surface soils samples are provided in Appendix B.

3 5.0 Existing Site Conditions
The proposed sewer replacement is located along the existing paved roadways and rear alleys. The Montebello Sewer Program alignment crosses several streets. Existing roadways are primarily residential streets with one lane in each direction. Rear alleys are paved alleyways with concrete gutters in the middle. Multiple underground and overhead utilities are located along the project alignments.

6.0 Subsurface Conditions
Subsurface information obtained from the EMI field exploration indicates that the project area is underlain by alternating layers of coarse-grained soils consisting of dense to very dense silty sand, clayey sand, sandy silt, and sand and fine-grained soils consisting of stiff to hard clay and silty clay. Variable amounts of gravel were also encountered in a few of the borings at various depths.

The above soil description is general and is intended to describe the subsurface in very broad terms.

The soil description above should not be construed to mean that the subsurface profile is uniform, and that soil is homogeneous along the project alignments. Details on the stratigraphy at each exploratory location are shown on the borehole logs provided in Appendix A.

7.0 Groundwater
During the field investigation performed by EMI along the project alignments, groundwater was not encountered in any of the borings advanced to maximum depth of 15.5 feet below existing ground surface.

The California Department of Water Resources Data Library was reviewed for additional groundwater level readings in the vicinity of the project site. One well is located at a distance of 5,000 feet west of the project site. The well shows a highest groundwater elevation of about +102 feet; the ground surface of this well is about +193 feet.

It should be noted that the groundwater elevation can fluctuate due to variations in seasonal rainfall, runoff volume, nearby irrigation, changes in or addition of flood control improvements, groundwater extraction and recharge of local and regional aquifers, construction activities, and other manmade or natural conditions. Therefore, the groundwater elevation during construction may be different from those measured in the past and recent borings.

8.0 Corrosion Testing
Representative soil samples collected from throughout the project area were tested to determine corrosivity including minimum resistivity, pH, soluble sulfate content, and soluble chloride content. Four soil samples were tested for corrosivity, and the results are summarized in Table 2.

According to the Caltrans Corrosion Guidelines V3.2 (Caltrans, 2021), soils are considered corrosive if the pH is 5.5 or less, chloride concentration is 500 parts per million (ppm) or greater, or sulfate concentration is 1,500 ppm or greater. Based on Caltrans criteria, on-site soils are considered non-corrosive to concrete or metal.

We understand that the values may be used to estimate potential corrosive characteristics of the on-site soils with respect to contact with the various underground materials which will be used for project construction. We recommend that corrosive potential of the on-site soils to underground ferrous metals should be evaluated by a corrosion engineer.

9.0 Trenching and Shoring
Based on OSHA excavation safety guideline, any excavation deeper than 4 feet should be sloped or shored. Due to the limited space along the roadway, we anticipate that shored temporary excavation with vertical sidewalls will be required for the project. The anticipated shoring system might be cantilevered shoring or braced shoring. For cantilevered shoring retaining level ground, a lateral active earth pressure of 42H psf (H is the total height of excavation) is recommended. For the design of braced shoring, total lateral earth pressure of 36H pounds per foot (H is the total height of excavation) is recommended. The total lateral earth pressure should be considered at the mid height of the shoring. The lateral earth pressures provided above do not include surcharge pressures. Therefore, if applicable, lateral pressures due to surcharges from vehicle traffic or adjacent structures should be added to the above lateral earth pressures.

Design of temporary shoring is the contractor’s responsibility during construction. Heavy construction equipment should not be used immediately adjacent to shoring due to large lateral pressures induced by such equipment unless the shoring is designed to accommodate resulting pressures. Excavated soil or construction materials should not be stockpiled adjacent to shoring or open excavations. Stockpiled soil and construction materials should be set back a distance at least equal to the height of the excavation. It should be noted that it is the responsibility of the contractor to oversee the safety of the workers in the field during construction. The contractor shall conform to all applicable occupational safety and health standards, rules, regulations, and orders established by the State of California. The geotechnical consultant should review the trench shoring design and safety plan to confirm that recommendations presented in this memorandum have been applied to the design.

5 Qualified geotechnical personnel should inspect temporary slopes for erosion and sloughing, and should inspect temporary shoring for signs of instability and deformations, during construction on a daily basis.

The contractor is responsible for evaluating the ease/difficulty of installing and extracting structural elements for temporary shoring walls in contact with the ground.

10.0 Trench Bottom Preparation and Backfill
Backfill and excavation should follow Caltrans Standard Plan Sheet A62D for concrete pipes.

Typically, backfill materials placed on the sides and underneath the pipe should be either granular soils with a Sand Equivalent (SE) of at least 30 or Structure Backfill. On-site materials may be used as backfill above the top of the pipe. We recommend the materials specifications and minimum relative compaction presented in Table 3.

Table 3. Summary of Trench Backfill Materials Specifications Caltrans Standard Plan
Sheet A62D Designation Materials Specifications Min. Relative Compaction Structure Backfill Caltrans Structure Backfill with a minimum Sand Equivalent (SE) of 30 95%
Roadway Embankment Same as above or Onsite Soils 90%
Any loose materials, overside particles larger than 2 inches and/or unsuitable materials encountered at the bottom of the excavation should be removed and replaced with adequate bedding materials. The storm drain pipe subgrade should be level, uniform, firm and free of loose materials. The subgrade should be properly graded to provide uniform bearing and support to the entire section of the storm drain pipe. If pumping or yielding of the subgrade is observed during construction, appropriate measures should be taken by the contractor to stabilize the subgrade.

11.0 R-Values
Two soil samples, collected from the upper five feet of the existing subgrade, were tested to determine their R-value, percent passing No. 200 Sieve, and Plasticity Index. The test results along with the USCS soil type are presented in Table 4.

Based on the above, EMI recommends using a design R-value of 4 for flexible pavement design.

The project site is located in the “South Coast” climate region.

6 12.0 Pavement Structural Sections
Based on the information provided by the client, the existing roadway within the project alignments may be reconstructed with new asphalt concrete (flexible pavements) pavements. The flexible pavements were designed using the web-based program developed by Caltrans and the methodology given in Chapter 630 of Caltrans Highway Design Manual (2023a).

As shown in the table below, a 20-year design life Traffic Index (TI) values of 6 to 9 are considered.

Based on the laboratory test results, a design R-value of 4 is recommended.

The recommended flexible pavement sections are presented in Table 5.

9.0 0.55’ HMA-A / 1.00’ AB
Note: HMA-A = Hot Mix Asphalt (Type A); AB = Aggregate Base (Class 2)

13.0 Pavement Subgrade
A design R-value of 4 is recommended for the flexible pavement design. If the R-value of subgrade exposed during construction comes into question, the exposed soils should be sampled and tested during grading to verify the R-value. In locations where structural pavement sections will be constructed atop import fill (Select) materials, the Select Materials placed within four feet of the grading plane should have a minimum R-Value of 4 and a Plasticity Index of less than or equal to 12%.

Prior to placing the pavements, the exposed subgrade should be scarified to minimum depth of 10 inches, moisture conditioned and compacted to at least 90% relative compaction based on the maximum densities determined by ASTM D1557 or CT 216. Special care is required when compacting soils near buried utility lines, drainage devices, and other sensitive buried structures, to avoid damaging the existing facilities.

14.0 Pavement Materials and Construction
HMA should conform to requirements of Section 39 of the Caltrans Standard Specifications and Special Provisions. The asphalt specifications should include ¾-inch or 1-inch aggregate gradation with PG 64-10 binder for HMA-A thickness of 0.25-feet or greater.

For HMA dikes and miscellaneous areas, use 3/8-inch or 1/2-inch aggregate gradation and PG 64-10 asphalt binder. Recommended aggregate gradations for HMA miscellaneous areas and

7 HMA dikes are currently found in Section 39 of the Caltrans Standard Specifications (2023b) and Standard Special Provisions (2022).

For flexible pavement sections, prime coat shall be applied to the aggregate base material per Section 39-2.01C(3)(c) of Caltrans Standard Special Provisions (2022) prior to placing Hot Mix Asphalt. Tack coat shall be applied between successive layers of HMA as required by the specifications.

15.0 Limitations
This memorandum is intended for use by Mark Thomas & Company, Inc. (MTC) and the City of Montebello for the replacement of three sewer lines within the Montebello Sewer Program. This memorandum is based on the project as described herein and the information obtained from the exploratory boreholes at the approximate locations shown on the enclosed plan. Findings and recommendations contained herein are based on the results of the field investigation, laboratory soil tests, and geotechnical engineering analyses. In addition, soils and subsurface conditions encountered in the exploratory boreholes are presumed to be representative of the project area.

However, subsurface conditions and soils characteristics between exploratory boreholes can vary.

The findings reflect an interpretation of the direct evidence obtained. The recommendations presented in this memorandum are based on the assumption that an appropriate level of quality control and quality assurance (inspections and tests) will be provided during construction. EMI should be notified of any pertinent changes in the project plans or if subsurface conditions are found to vary from those described herein. Such changes or variations may require a re-evaluation of recommendations contained in this memorandum.

The data, opinions, and recommendations contained in this memorandum are applicable to the specific design elements and locations which are the subject of this memorandum. The data, opinions, and recommendations have no applicability to any other design elements or to any other locations. Any and all subsequent users accept any and all liability resulting from any use or reuse of the data, opinions, and recommendations without the prior written consent of EMI.

EMI has no responsibility for construction means, methods, techniques, sequences, procedures, or safety programs in connection with the construction, for the acts or omissions of the Contractor, or any other person performing any of the design or construction, or for the failure of any worker to carry out the construction in accordance with the Final Construction Drawings and Specifications.

Services performed by EMI have been conducted in a manner consistent with that level of care and skill ordinarily exercised by members of the profession currently practicing in the same locality under similar conditions. No other representation, expressed or implied, and no warranty or guarantee are included or intended.

The thread can barely be rolled, and the lump cannot be formed when drier than the plastic limit.

The thread is easy to roll, and not much time is required to reach the plastic limit; it cannot be rerolled after reaching the plastic limit. The lump crumbles when drier than the plastic limit.

It takes considerable time rolling and kneading to reach the plastic limit. The thread can be rerolled several times after reaching the plastic limit. The lump can be formed without crumbling when drier than the plastic limit.

Weak Crumbles or breaks with handling or
little finger pressure.

Moderate
Strong
Crumbles or breaks with considerable
finger pressure.

Will not crumble or break with finger
pressure.

CITY OF MONTEBELLO

CITY COUNCIL AGENDA STAFF REPORT
TO: Honorable Mayor and City Council Members
FROM: Raul Alvarez, City Manager

BY: Cesar Roldan, Director of Public Works
SUBJECT: ADOPT RESOLUTION NO. 25-42 ADOPTING THE 2025 SANITARY SEWER MANAGEMENT PLAN AND AUTHORIZING THE RECERTIFICATION WITH THE STATE WATER RESOURCES CONTROL

BOARD (SWRCB)
DATE: June 11, 2025
RECOMMENDATIONS:

It is recommended that the City Council:

1. Approve Resolution No. 25-42 adopting the 2025 Sewer System Management Plan; and

2. Authorize the Director of Public Works to re-certify the 2025 Sanitary Sewer Management Plan with the State Water Resources Control Board (SWRCB); and

3. Take such additional, related action that may be desirable.

FISCAL IMPACT:

There is no fiscal impact associated with the adoption of the Sewer System Management Plan.

BACKGROUND/DISCUSSION:

The City updates the Sanitary Sewer Management Plan (SSMP) to remain consistent with General Plan, provisions of wastewater service, and to comply with statewide General Waste Discharge Requirements (GWDR). To provide a consistent, statewide regulatory approach to address sanitary sewer spills, the State Water Resources Control Board (SWRCB) adopted statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order No. 2022-0103-DWQ (Sanitary Sewer Systems General Order) on December 6, 2022. The Sanitary Sewer Systems General Order

CITY COUNCIL AGENDA REPORT - MEETING OF JUNE 11, 2025

(Order), made effective by the SWRCB on June 5, 2023, requires public agencies that own or operate sanitary sewer systems to develop and implement sewer system management plans and report all sanitary sewer spills to the State Water Board’s online California Integrated Water Quality System (CIWQS) Sanitary Sewer System Database.

The City is required to comply with these requirements, which indicate that an updated and approved SSMP must be adopted by August 4, 2025.

The SSMP undergoes an internal audit at a minimum every two years and requires approval by the City Council (Attachment A) every five years, or when the audit identifies a major change is needed. The 2025 SSMP (Attachment B) is a living document that requires updates that rely on the varying changes to the City’s programs, policies, statewide mandates, etc. in compliance with the new order. The SSMP is an effective tool for the ongoing management of the City’s sanitary sewer network and preventing sanitary sewer overflows. The SSMP focuses on the City’s effort to comply with State measures and regulations.

ENVIRONMENTAL:

The SSMP update primarily incorporates continuing administrative and maintenance activities, including updates to procedures and operations of existing facilities in accordance with GWDRs, and as a result, the SSMP is not subject to the California Environmental Quality Act (CEQA) in accordance with Section 15378(b)(2) of California Code of Regulations, Title 14, Division 6, Chapter 3 Under the California Code of Regulations, Title 14, Division 6, Chapter 3 (CEQA Guidelines); provided, that even if CEQA applied, the administrative and maintenance activities of the SSMP update, primarily ministerial in nature, would involve operation, repair, maintenance or minor alteration of existing public facilities involving negligible or no expansion of existing or former use and would qualify as a Class 1 exemption under CEQA Guidelines Section 15301. Accordingly, no further environmental review is necessary.

ANALYSIS:

N/A
SUMMARY:

Staff recommend City Council approve Resolution No. 25-42 to adopt the 2025 Sewer System Management Plan; and, authorize the Director of Public Works to re-certify the 2025 Sanitary Sewer Management Plan with the State Water Resources Control Board.

WHEREAS, these Waste Discharge Requirements (WDRs) serve as the regulatory framework for all public agencies that own or operate sanitary sewer collection systems exceeding one mile in length and that transport untreated or partially treated wastewater to a publicly owned treatment facility;
WHEREAS, the objectives of WDRs are to reduce the frequency and volume of Sanitary Sewer Overflows (SSOs) by requiring public agencies to properly manage, operate, and maintain their wastewater collection system. This is to be done by developing, implementing, and updating an agency-specific Sewer System Management Plan (SSMP);
WHEREAS, on December 6, 2022, the SWRCB adopted Order No. 2022-103- DWQ, Statewide WDRs - General Order for Sanitary Sewer Systems, which became effective on June 5, 2023, and superseded Order No. 2006-0003; and WHEREAS, the SSMP update primarily incorporates continuing administrative and maintenance activities, including updates to procedures and operations of existing facilities in accordance with WDRs, and as a result, the SSMP is not subject to the California Environmental Quality Act (CEQA) in accordance with Section 15378(b)(2) of California Code of Regulations, Title 14, Division 6, Chapter 3 Under the California Code of Regulations, Title 14, Division 6, Chapter 3 (CEQA Guidelines); provided, that even if CEQA applied, the administrative and maintenance activities of the SSMP update, primarily ministerial in nature, would involve operation, repair, maintenance or minor alteration of existing public facilities involving negligible or no expansion of existing or former use and would qualify as a Class 1 exemption under CEQA Guidelines Section 15301.

DEFINITIONS
Geographical Information System (GIS) – A database linked with mapping, which includes various layers of information used by government officials. Examples of information found on a GIS can include a sewer map; sewer features such as pipe location, diameter, length, material, condition, last date cleaned or repaired. The GIS also typically contains base information such as streets and parcels.

Infiltration/Inflow (I/I) – Infiltration is generally considered to be extraneous water that enters the sewer system over longer periods of time, such as groundwater seepage through cracks in the sewer. Inflow is generally considered to be extraneous water that enters the system as a direct result of a rain event, such as through defects in the sewer.

While it is impossible to control all I/I, it is certainly desirable to reduce I/I when costeffective.

Lateral – The portion of sewer that connects a home or business with the main line in the street.

Stoppage – A build-up of debris in the sewer, which stops the flow of wastewater and allows the water to back up behind the stoppage, sometimes causing an overflow. Also called blockage.

Blockage – A build-up of debris in the sewer, which stops the flow of wastewater and allows the water to back up behind the stoppage, sometimes causing an overflow. Also called a stoppage.

Wastewater Collection System – All pipelines, pump stations, and other facilities upstream of the head works of the wastewater treatment plant that transport wastewater from its source to the wastewater treatment plant.

SEWER SYSTEM MANAGEMENT PLAN (SSMP)

INTRODUCTION
On May 2, 2006 the State Water Resources Control Board (SWRCB) adopted a Statewide General Waste Discharge Requirements (WDR) and Monitoring and Reporting Program (MRP), for sanitary sewer systems by issuing Order No. 2006-003 (Appendix A). The regulations in the Order were in response to growing public concern about the water quality impacts of Sanitary Sewer Overflows (SSOs), particularly those that cause beach closures, adverse effects to other bodies of water, or pose serious health and safety or nuisance problems. The order requires all federal and state agencies, municipalities, counties, districts, cities, and other public entities that own or operate a sanitary sewer system greater than one mile in length to comply with the requirements of the WDR and to develop and implement a Sewer System Management Plan (SSMP).

The City’s original SSMP was adopted by the City Council and certified with the SWRCB.

Pursuant to Section D.14 of the WDRs which requires that the SSMP is required to be updated every six (6) years.

Additionally, SWRCB Order WQ 2008-0002-EXEC amended the WDR on February 20, 2008. The revised order requires that the notification and reporting of sanitary sewer overflows (SSO) to regulatory agencies follow a strict timeline. SWRCB Order WQ 2013- 0058-EXEC amended the Monitoring and Reporting Program (MRP) (Order WQ 2008- 0002-EXEC) for the SSSWDR effective September 9, 2013. Several major changes were made to the public notification, reporting, water quality monitoring, recording keeping, and certification requirements. The revised order also requires the submission of an electronic copy of the SSMP to the SWRCB or the web address where it posted. This SSMP has been prepared in accordance with the following:
• SWRCB Order 2006-0003-DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer System.
• SWRCB Order WQ 2008-0002-EXEC, Adopting Amended Monitoring and Reporting Requirements for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
• SWRCB Order WQ 2013-0058-EXEC, Amending Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.

City of Montebello
Sewer System Management Plan (SSMP) May 2025
2 The SSSWDR includes directives for the management, operation, and maintenance of the sanitary sewer system as well as proper control, containment, and cleanup of any SSOs that occur. They also require that SSOs be reported to the SWRCB using the online California Integrated Water Quality System (CIWQS).

In compliance with the SWRCB guidelines, this document is prepared to meet the objectives contained in the WDR Order. The City of Montebello operates and maintains the sanitary sewer conveyance system pipelines serving its population of approximately 62,640. The City’s sewer lines discharge to a network of trunk sewer lines owned and operated by the Los Angeles County Sanitation Districts (LACSD).

The document is divided into 11 chapters, which closely align with the respective provisions contained in the WDR’s. Every section or subsection of each chapter addresses one of the key elements of the SSMP directive. The document, with other existing Agency Programs referenced herein, constitute the City’s SSMP. By implementing the procedures contained in this SSMP, the occurrence of SSOs should decrease or possibly be avoided throughout the City’s Sanitary Sewer Collection System.

The organization of this SSMP is consistent with the SWRCB guidelines and includes the following eleven SSSWDR elements:

1. Goals

2. Organization

3. Legal Authority

4. Operation and Maintenance Program

5. Design and Performance Provisions

6. Overflow Emergency Response Plan

3 1.0 GOALS AND ACTIONS

1.1 Goals of SSMP:

1. The City’s sanitary sewer collection system is properly operated, maintained and managed to reduce frequency and severity of sanitary sewer overflows (SSOs) and their potential impacts on public health, safety, and the environment.

2. When an SSO occurs, prompt action is taken to identify, contain, and remove the cause; report the event to the appropriate regulatory authorities; and notify the public in a timely manner,

3. All SSOs, system deficiencies, and remedial actions taken are well documented, or

4. The City’s sewer system operators, employees, contractors, responders, and other agents are adequately trained and equipped to address an SSO event.

5. The City’s sewer system is designed, constructed and funded to provide adequate capacity to convey base flows and peak flows, while meeting or exceeding applicable regulations, laws and the generally accepted practices relative to sanitary sewer system operation and maintenance.

1.2 Actions of SSMP:

1. Conduct a planned and scheduled maintenance program to minimize the risk and occurrence of SSOs.

2. When an SSO occurs, respond to the incident in a timely manner and undertake feasible remedial actions to contain the overflow, including stopping the flow from reaching the storm drain, if possible.

3. Stop the sewer overflow as soon as possible and limit public access to the overflow area to prevent public contact with any wastewater contamination.

4. If possible, completely recover the overflow sewage, return it to the sewer system, and clean up the contaminated area.

5. Gather and compile all pertinent information regarding the sewer overflow incident, investigate as necessary to determine probable cause, document

12 3.0 LEGAL AUTHORITY
The SSSWDR Section D.13.(iii) requires that the City show through its existing codes, ordinances, service agreements or other legally binding procedures that the City possesses the legal authority to:
1) Prevent illicit discharges into its sanitary sewer system (examples may include I/I, stormwater, chemical dumping, unauthorized debris and cut roots, etc.). 2) Require that sewers and connections be properly designed and constructed. 3) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the City.
4) Limit the discharge of Fats, Oils, and Grease (FOG) and other debris that may cause blockages.
5) Enforce any violation of its sewer ordinances.

3.1 Legal Authority
The City’s legal authority to operate a sanitary sewer collection system is derived from its incorporation as a City and is contained within Municipal Code Chapter 15, Division 20 (California Plumbing Code), and Chapter 15.04 (California Building Code), which adopt by reference the 2009 Edition of the California Plumbing Code and Building Code.

City Ordinance Title 8, Section 36.030 prohibits the illicit discharges, dumping, and nonstorm water discharges into storm water drains. Any person causing an illicit discharge may be required to pay for the cost of clean-up and remediation. Title 8, Section 36.140 allows criminal penalties for any violation of the Sewer and Industrial Waste Ordinances.

Violations for an infraction can be convicted under City Ordinance 8.32.050.

3.1.1 Prevention of Illicit Discharges into the Sanitary Sewer System City Ordinance and codifications of the Municipal policy for Sanitary Sewer and Industrial Waste were adopted for implementing many of the required SSMP elements and plans.

The City adopted Ordinances 2347 and 2356 dated December 13, 2011 and February 26, 2014, which incorporate most provisions of the California Plumbing Code, as its plumbing code. The Chapter 15.20 of the City of Montebello Ordinance 2356 – California Plumbing Code, which regulates sanitary sewers and industrial waste in the City, as its Sanitary Sewer and Industrial Waste use Ordinance.

City of Montebello
Sewer System Management Plan (SSMP) May 2025
13 The City of Montebello Plumbing Code Chapter 12, Sections 04.270 and 04.280- prohibits the unauthorized discharge connection to any sanitary sewer collection system. The City Code, Chapter 5, Section 16.230 and Chapter 8, Section 12.030 and 36.140, prohibits the illegal dumping of offensive or damaging substances such as chemicals, debris, etc.

This program consists of sewer line cleaning and maintenance program, which includes closed circuit television (CCTV) and other mechanisms to detect I/I. The Annual Maintenance of Sewer System agreement is signed yearly for services including manhole inspection, CCTV of pipes, preventative pipe cleaning, as-needed pipe cleaning and sewer remediation. The City will consider adoption of new Ordnances similar to the LA County Title 20, Section 20.24.080, requires that property owners be responsible for maintenance of their house laterals, including the elimination of cracks, tree roots, and other debris.

The City has no responsibility for the maintenance or replacement of house laterals. These laws combined constitute the City’s legal authority to prevent illicit discharges into the sewer system.

3.1.2 Legal Authority to Require that Sewers and Connections be properly Designed and Constructed
The City has the responsibility for the review and approval of plans and specifications for the construction and dedication of sanitary sewers, house laterals and sewer-related appurtenances through the development processes of the Department of Public Works, Development Engineering Division. The Division ensures all construction within the public right-of-way complies with adopted codes, ordinances, and engineering standards.

The City Code Chapter 12, Sections 04.270 and 04.280 require a permit from the Public Works Department. The permit requires submission of design of new main-line sewers and sewer service laterals in the City that comply with Sewer Master Plan dated 2011, Sewer Design Criteria and Maintenance. The City will consider adoption of new Ordinance similar to the LA County Code Title 20, Section 20.32.350 of the Code requiring that the design of new house laterals also conform to the requirements of Part 3, Chapter

20.32 of the Code unless otherwise covered by the LA County Plumbing Code Title 28.

The LACO Code, Section 20.24.080, requires property owners to maintain their house laterals, including the elimination of cracks, tree roots, and other debris. A similar requirement is found in Section 101.3.2 of the LACO Plumbing Code Title 28.

The City staff is currently uses LA County Code Title 20, Section 20.32.420, for the construction of a collection sewer system to conform to all the requirements prescribed by Division 2, of the Code, the Standard Specifications for Public Works Construction (“Green Book”) and by the Special Provisions and Standard Plans, all on file in the office

City of Montebello
Sewer System Management Plan (SSMP) May 2025
14 of the City Director of Public Works. The inspection of new main-line sewers and pumping plants to ensure proper construction is covered under Section 20.30.590 of the LA County Code.

3.1.3 Legal Authority to Ensure Access for Maintenance, Inspection, or Repairs The City Code, Chapter 12, Section 02.280 gives the City the legal right to set requirements to allow unrestricted maintenance access to the public sewer collection system located in the easements. The access shall be secured through City’s enforcement of the requirement for legally recorded sewer easements around all public sewer appurtenances located in private properties. Sewer easements are detailed on the sewer construction plans and are thoroughly reviewed by the City for adequacy in size and accuracy of alignment during the plan check process. Plan checkers take special care to ensure that maintenance crews will have sufficient access for the movement of equipment and materials for both routine and emergency repair or construction work on the system.

3.1.4 The City to Limit the Discharge of FOG and other Debris that may cause Blockage
The City Code Chapter 8, Section 04.010 states that the "Health and Safety Code of the County of Los Angeles," the same being Title 11 of the Los Angeles County Code, and the "Public Health License Code of the County of Los Angeles," the same being Division 1 of Title 8 of the Los Angeles County Code, as those titles have been amended through and including March 23, 2005, are adopted as the health and safety code for the city.

The City by adopting the California Plumbing Code per Section 15.20.010 of the City Municipal Code and LA County Code, Title 20 to be adopted by the City, has the legal authority to satisfy this element of the WDR.

The LA County Plumbing Code - Title 28, which will be adopted by the City requires the installation of grease interceptors at restaurants and other food establishments that generate grease in the City. Section 20.36.400 of the LACO Code prohibits the discharge of FOG and other substances that may, among other things, clog, obstruct, fill, or necessitate frequent repairs, cleaning out or flushing of sewer facilities, in the Sewer System. The LA County Code, Section 20.36.560 gives the Director of Public Works the authority to require the installation of treatment facilities, including grease interceptors, at any facility that generates FOG in the amount that will damage or increase the maintenance costs of the sewer collection system. The Director of Public Works shall be authorized to enforce and administer all of the provisions for FOG.

2) Describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders;
3) Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and TV

City of Montebello
Sewer System Management Plan (SSMP) May 2025
16 inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed for the capital improvement plan;
4) Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and 5) Provide equipment and replacement part inventories, including identification of critical replacement parts.

4.1 City Sewer Mapping System
The City maintains as-built plans of the Collection System CADD (Computer-Aided Design and Drafting) Maps which includes road names, property lines, Right-of-Ways, etc.

Information generated by the CADD is printed on Index Map Sheets stored by the City Public Works Department Engineering Division. The Index Maps are also kept at the City Public Works Department Field Maintenance Yards. The maps are updated, as necessary, to reflect any changes in the system. The county provides access to up-to-date maps of the sewer system which include pipe and manhole locations, diameter, material and flow direction via interactive GIS mapping on:
https://dpw.lacounty.gov/smd/sewernetwork/

4.2 Preventive Operation and Maintenance Program
The City contracted Los Angeles County to provide Sewer Maintenance including: yearly visual inspection of 2,000 manholes, CCTV inspection of pipes (20% of system based on a 5-year cycle), Preventative Pipe cleaning (20% of system based on 5-yr cycle), AsNeeded pipe cleaning ($100,000 budget), Sewer Remediation (Point Repair budget $105,000) and Sewer Remediation (Pipe Lining Budget $160,000). The Operation and Maintenance Program has been developed in conjunction with the contract through Los Angeles County to provide the tools and procedures for maintaining its gravity sewer system with adequately trained staff and sewer contractors possessing adequate knowledge, skills, and abilities. The goal of the Operation and Maintenance Program is to operate an efficient sanitary sewer system at an optimal level to eliminate sanitary

City of Montebello
Sewer System Management Plan (SSMP) May 2025
17 sewer overflows and thereby protect public health and the environment. The maintenance contract provides after-hour services to the City such as Stand-by, callback, and other sewer emergency services.

Funds are managed and administered by the City to sustain the maintenance programs by contracting with LA County, the City is committed to a regular sanitary sewer maintenance program in order to reduce and prevent SSOs and to extend the useful life of the system including routine maintenance and cleaning of wastewater facilities and pipelines as addressed on the following sections.

4.2.1 Sewer Line and Manhole Inspection
The interior and exterior of manholes are inspected bi-annually for any structural defects, sewage flow condition, presence of vermin or rodents, deleterious industrial waste, odors and any signs of unusual settlement around the manholes and along sewer alignments.

4.2.2 Gas Trap Manholes and Siphons
On a monthly basis, these facilities are inspected and cleared of any stoppages or flow restrictions.

4.2.3 Drop Manholes
These facilities are inspected and cleared of stoppages and flow restrictions on variable frequencies based on prior inspection records.

4.2.4 Sewer Line Cleaning
Sewer lines are cleaned by hydro jet or rodding. The Sewer Maintenance Division contract states that 20% of the system is inspected and cleaned based on a 5-yr cycle based on inspection records. Sewer lines known to accumulate grease, garbage grinds or sand are put on monthly, quarterly, or semi-annual cleaning schedule and those prone to root growth are periodically rodded or chemically treated.

4.2.5 Vermin and Rodent Control
Sewers infested by insects are chemically treated. Those infested by rodents are baited.

4.2.6 Work Scheduling
The Sewer Maintenance Division is in the process of implementing Cityworks Maintenance Management system to schedule and track maintenance activities. The activities field crew performs are recorded in various forms such as service requests, cleaning reports,

City of Montebello
Sewer System Management Plan (SSMP) May 2025
18 sewer maintenance daily reports, manhole adjustments, overflow report forms, etc., and stored in the system.

4.3 Rehabilitation and Replacement Plan
The City’s rehabilitation and replacement plan is based on the 2011 Sewer System Hydraulic Analysis prepared by Infrastructure Engineering Corporation (IEC). The analysis presents wastewater flow projections at the existing lines for 5-year time intervals. These projections were used to identify system deficiencies and to develop a Capital Improvement Plan (CIP) that outlined a strategy to mitigate them. The City’s 2011 Sewer System Master Plan was also completed by IEC and built on the 2009 analysis by updating the existing wastewater flows and recommended system capital improvements. These updates were done considering the critical findings of the 2011 Sewer Closed Circuit Television (CCTV) and Condition Assessment Report and the 2009 Sewer Flow Monitoring Report, both completed by IEC. The 2009 Sewer Closed Circuit Television (CCTV) and Condition Assessment Report presented the results of televising gravity mains with missing hydraulic information, areas known to have fats, oils, and grease (FOG) problems, and those areas identified as deficient in the 2009 analysis.

4.3.1 Capital Improvement Programs
The primary goal of the Capital Improvement Program (CIP) is to provide the City of Montebello with a long range-planning tool for implementing its sewer infrastructure improvements in an orderly manner and providing a basis for financing these improvements. To accomplish this goal, the program is phased based upon the implementation cost of the facilities, the quantity of work the City can reasonably administer each year, and the funds available for these projects. The capital improvements needed will be identified as a result of the assessment of the system through capacity analyses and physical TV inspections.

Updating the Capital Improvement Program if recommended as the CCTV video from Sewer Maintenance District would be utilized and the remainder of the City sewers would be videoed and rated. The capital improvement projects would be selected primarily with consideration of the health and safety of the public and protection of the environment by minimizing the possibility of spillages. The highest priority would be assigned to the projects that will help alleviate known maintenance problems and line segments that have been shown through CCTV to be structurally deficient. The second highest priority has been assigned to projects identified by hydraulic evaluations and modeling with existing capacity deficiencies. The third priority would be replacement of aged pipelines.

Pending the completion of the videoing of the sewers, the initially recommended CIP has

City of Montebello
Sewer System Management Plan (SSMP) May 2025
19 been based upon the best information currently available. The CIP should be updated as new information becomes available from sources such as CCTV inspections and from maintenance crew observations. The CIP should also be updated based on any major change in the City’s General Plan. The project priorities may be adjusted to take advantage of concurrent construction such as street paving projects or adjacent infrastructure work.

4.3.2 Condition Assessment Program
There are currently about 89.4 miles of sewer lines within the City. The existing City collection sewer facilities are listed in Appendix D. The existing sewer pipes, ranging from 8 to 18 inches in diameter, are predominantly of vitrified clay pipe material. Naturally, these sewer lines age and structural problems such as cracks, joint separation, root intrusion, etc. will develop. To ensure that these problems are properly mitigated, the WDR requires that the City has a program in place to minimize and correct them in conjunction with the Sewer Maintenance District’s annual contract.

The City does not currently charge a monthly user fee to customers. This is a topic of discussion for the City Council as the system ages.

4.3.3 Equipment Maintenance and Replacement Policy
The equipment utilized in the maintenance of the City’s sewer facilities is owned by the Sewer Maintenance District. The Maintenance District has full responsibility for the maintenance, replacement and liability of the equipment.

4.4 Training for Field Operations Personnel and Contractors The City recognizes the importance of consistent staff training and documentation of training sessions. The City’s wastewater staff are trained on wastewater operations and maintenance policies, procedures, safety policies, and equipment. The Director of Public Works is responsible for documenting the details of each training event including dates, content, and participating employees.

All personnel needed for the operation and maintenance of the City’s sewer system will be provided by the City contractor. The training of City personnel is a function of the City Public Works Department.

The City’s sewer construction projects are awarded to carefully selected contractors with well trained and qualified personnel for any given project. The designed plans and specifications for City’s sewer construction projects contain detailed instructions on City’s permitting requirements, standards and policies that must be adhered to by contractors
