QSD#

The SWPPP will be revised when:

• There is a 2022 CGP violation (2022 CGP Section VI.Q.1);

• There is a reduction or increase in total disturbed acreage (2022 CGP Section III.F.2. and F.4);

• BMPs are not effective and are not resulting in a reduction or elimination of pollutants in stormwater discharges and authorized non-stormwater discharges (2022 CGP Section VI.Q.1 and Attachment E Section III.C.5);

• There is a change in the project duration that changes the project Risk Type (2022 CGP Section III.F.1);

• Dischargers with projects where all construction activities (including passive treatment, active treatment systems, and/or active equipment) will be suspended for 30 days or more (2022 CGP Section III.G);

• There is a change in construction or operations that may affect the discharge of pollutants to surface waters, groundwater(s), or a municipal separate storm sewer system (MS4) (2022 CGP Sections IV.O. and VI.Q.1); or

When deemed necessary by the QSD. The QSD has determined that the changes listed in Table 1-1 can be field determined by the QSP. All other changes will be made by the QSD as formal amendments to the SWPPP. Note that the 2022 CGP requires that the QSD “revise the SWPPP to address potential problems identified by visual inspections, sampling data, comments from a QSP, or their own site observations (2022 CGP Section V.C.2.).

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 Camp Pendleton AMSA project comprises approximately of 6.56 acres. The Project is located at Camp Pendleton South, California 92058. The property is owned and being developed by the US Army Corps of Engineers. The project’s location is shown on the Site Maps in Appendix A.

1.2 PERMIT REGISTRATION DOCUMENTS

Required Permit Registration Documents (PRDs) shall be submitted to the State Water Board via the Stormwater Multi Application and Report Tracking System (SMARTS) by the LRP or DAR. The project-specific PRDs include (2022 CGP Section III.A):

1. Notice of Intent (NOI);

CASQA Traditional SWPPP Template 1-2 August 2023

2. Risk Level Determination (Construction Site Sediment and Receiving Water Risk Determination);

3. Site Drawings and Map;

4. SWPPP;

5. Applicable plans, calculations, and other supporting documentation for compliance with the Phase I or Phase II municipal separate storm sewer system (MS4) post construction requirements or the post-construction standards of the 2022 CGP:

• Attachment or web-source containing the applicable Phase I or Phase II MS4 post construction requirements;

• The post construction plans and calculations submitted to or approved by the applicable Phase I or Phase II MS4; and/or

• Post-construction water balance calculation;

Section 2 Project Information

2.1 PROJECT AND SITE DESCRIPTION

2.1.1 Site Description

The Camp Pendleton AMSA project site is Risk Level 1 that comprises approximately 6.56 acres and is located at Camp Pendleton South, California 92058. The project site is located approximately 0.5 miles west of interstate 5 and adjacent to Oceanside Harbor. The project is located at latitude 33°12'48.40"N, and longitude 117°23'49.21"W and is identified on the Site Map in Appendix A.

2.1.2 Existing Conditions

As of the initial date of this SWPPP, the project site is fully developed. Most of the existing site is a building, parking lot and storage yard. The project site was previously developed with a public land use. There are no known historic sources of contamination at the site. Soil sampling and analysis is required when soil contamination is found or suspected. The results of this analysis are in Appendix Q.

2.1.3 Existing Drainage

The project site elevation is relatively flat. The elevation of the project site ranges from 25 to 13 feet above mean sea level (msl). Surface drainage at the site currently flows north to southwest and southeast. Stormwater is conveyed through surface runoff. Existing site topography, drainage patterns, and stormwater conveyance systems are shown on Site Maps in Appendix A.

The project discharges to the Oceanside. Oceanside Harbor eventually discharges into the Pacific Ocean. The water quality impairments (303 (d) list and TMDLs identified in the 2022 CGP Table H-1 for the receiving waters are identified in the Table 2-1.

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 1.

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 via a site-specific analysis. The risk level is based on project duration, location, proximity to impaired receiving waters, and soil conditions. A copy of the Risk Level determination submitted on SMARTS with the PRDs is included in Appendix B.

2.5 CONSTRUCTION SCHEDULE

The site sediment risk was determined based on construction taking place between April 1, 2024 to September 18, 2026. 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.

CASQA Traditional SWPPP Template 2-5 August 2023

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.

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 the Site Map 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 soils are found on site, and the responsible party cannot be identified or fails to take action, soils 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

Based on the project’s receiving water and the pollutant source assessment, the following TMDLs are applicable to the project (See 2022 CGP Attachment H).
