100.1 Introduction

The proposed Project is located in Pauma. The address is 16971 Highway 76, Pauma Valley, CA 92061.

Please refer to the site and vicinity maps included in Attachment B.

In general, the SWPPP has been prepared to comply with the State of California General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities (State Water Resources Control Board Order No. 2009-0009-DWQ, as amended by 2010-0014-DWQ). Please refer to Attachment A for a copy of the General Permit.

More specifically, the SWPPP has been prepared to address the following objectives:

1. All pollutants and their sources, including sources of sediment associated with construction, construction site erosion and all other activities associated with construction activity are controlled;

2. Where not otherwise required to be under a Regional Water Quality Control Board (RWQCB) permit, all non-storm water discharges are identified and either eliminated, controlled, or treated;

3. Site BMPs are effective and result in the reduction or elimination of pollutants in storm water discharges and authorized non-storm water discharges from construction activity to the Best Available Technology/Best Control Technology (BAT/BCT) standard;

4. Calculations and design details as well as BMP controls for site run-on are complete and correct, and

5. Stabilization BMPs installed to reduce or eliminate pollutants after construction are completed.

Section 200 Project Information

200.1 Project and Site Description

This project involves the redevelopment of a Cal Fire Fire Station. The site is currently a fire station – Rincon Station 10. Construction activities for this project will involve, clearing and grubbing the site, demolition of existing buildings and utilities, construction of new building structures, parking lot, installing new site utilities, paving, grading, and a stormwater infiltration basin.

The following are estimates of the construction site:

• Construction site area: 2.75 acres

• Percentage impervious area before construction: 47%

• Runoff coefficient before construction: 0.58

• Percentage impervious area after construction: 49.0%

• Runoff coefficient after construction: 0.60

200.2 Storm Water Run-On from Offsite Areas

Minimal storm water run-on is anticipated.

200.3 Sediment and Receiving Water Risk Determination

Based upon the Risk Determination Worksheet included in Attachment B, the Project risk levels are as follows:

• Sediment Risk: Medium

• Receiving Water Risk: Low

• Combined Risk: Level 2

The Sediment Risk was determined by using: (1) the EPA Rainfall Erosivity Calculator to obtain an R Factor value, 75.8, and (2) the GIS Map Method to obtain a K Factor Value = 0.17 and LS Factor = 4.97.

The product of these values, which represents a Watershed Erosion Estimate, is approximately 64.043 tons/acre. Based upon the Risk Determination Worksheet included in Attachment B, Projects with a

SWPPP.docx Page 200-2

07/22/2021

Watershed Erosion Estimate more than 15 tons/acre and less than 75 tons/acre are classified as having a Medium Sediment Risk. Having Low Receiving Water Risk combined with the Medium Sediment Risk puts this project as a Combined Risk of Level 2.

The Receiving Water Risk was determined from answering the following watershed characteristics questions (from the Risk Determination Worksheet included in Attachment B):

2. Does the disturbed area discharge (either directly or indirectly) to a 303(d)-listed waterbody impaired by sediment?

ANSWER: No

3. Does the disturbed area discharge to a waterbody with designated beneficial uses of spawn & cold & migratory?

ANSWER: No

According to the Risk Determination Worksheet included in Attachment B, Projects that can answer “No” to both of the two watershed characteristics questions shown above are classified as having a Low Receiving Water Risk.

As a result, the SWPPP is required to comply with Attachment D (Risk Level 2 Requirements) of the General Permit.

The requirements for preparing and implementing Rain Event Action Plans are provided in Section 400.2.

If needed, refer to Section 100.8 for the requirements for a change in Project Risk Level.

Section 300 Best Management Practices

300.1 Schedule for BMP Implementation

BMPs will be implemented, modified, and maintained to reflect the phase of construction and the weather conditions. The schedule for deployment of BMPs is provided in Section 200.4.

300.2 Erosion Control and Sediment Control

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 storm water runoff. Erosion control BMPs protect the soil surface by covering and/or binding soil particles. This project will incorporate erosion control measures required by the contract documents, and other measures selected by the Contractor. This project will implement the following practices for effective temporary and final erosion control during construction:

1) Preserve existing vegetation where required and when feasible.

2) Apply temporary erosion control to remaining active and non-active areas as required by the

California Stormwater BMPs Handbook - Construction, and the contract documents. Reapply as necessary to maintain effectiveness.

3) Implement temporary erosion control measures at regular intervals throughout the defined rainy season to achieve and maintain the contract’s disturbed soil area requirements. Implement erosion control prior to the defined rainy season.

4) Stabilize non-active areas as soon as feasible after the cessation of construction activities.

5) Control erosion in concentrated flow paths by applying erosion control blankets, erosion control seeding, and lining swales as required in the contract documents.

6) Apply seed to areas deemed substantially complete by the Owner during the defined rainy season.

7) At completion of construction, apply permanent erosion control to all remaining disturbed soil areas.

Sufficient erosion control materials will be maintained on-site to allow implementation in conformance with Permit requirements and described in this SWPPP. This includes implementation requirements for active areas and non-active areas that require deployment before the onset of rain.

Implementation and locations of temporary erosion control BMPs are shown on the site maps in Attachment B and/or described in this section. The CASQA BMP Consideration Checklist in Attachment I indicates the

SWPPP.docx Page 300-2

BMPs that will be implemented to control erosion on the construction site.

• EC-1, Scheduling

• EC-2, Preservation of Existing Vegetation

• EC-3, Hydraulic Mulch

• EC-10, Velocity Dissipation Devices

Sediment Control Sediment controls are structural measures that are intended to complement and enhance 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. This project will incorporate sediment control measures required by the contract documents, and other measures selected by the Owner/Developer/Contractor.

Sufficient quantities of temporary sediment control materials will be maintained on-site throughout the duration of the project, to allow implementation of temporary sediment controls in the event of predicted rain, and for rapid response to failures or emergencies, in conformance with other Permit requirements and as described in this SWPPP. This includes implementation requirements for active areas and non-active areas before the onset of rain.

Implementation and locations of temporary sediment control BMPs are shown on the site maps in Attachment B. The CASQA BMP Consideration Checklist in Attachment I indicates all of the BMPs that will be implemented to control sediment on the construction site; these are:

If needed to justify site specific sediment risk using RUSLE.

700.3 Sample Collection and Handling

700.3.1 Sample Collection Preparation

Prior to the rainy season, all sampling personnel and alternates will review the Construction Site Monitoring Program. Qualifications of designated Contractor personnel describing environmental sampling training and experience are provided in Attachment N.

An adequate stock of supplies and equipment for monitoring will be available on the Project site or provided by the pre-approved laboratory 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. Sampling personnel will be available to collect samples in accordance will the sampling schedule.

Supplies maintained at the project site will include, but will not be limited to, surgical gloves, sample collection equipment, coolers, appropriate number and volume of sample bottles, identification labels, re-sealable storage bags, paper towels, personal rain gear, ice, Sampling Activity Log forms, and Chain of Custody (COC) forms (for Risk Level 2). The Contractor will obtain and maintain the field-testing instruments, as identified in Section 700.3.5, for analyzing samples in the field by Contractor sampling personnel.

Samples on the project site will be collected by the following or another pre-approved laboratory;

Alpha Analytical Laboratories, Inc 2722 Loker Avenue, West Suite A Carlsbad, CA 92010 760.930.2555

The chosen laboratory will obtain and maintain the field-testing instruments, as identified in Section 700.3.5, for analyzing samples in the field by their sampling personnel.

700.3.2 Sample Collection Procedures

Grab samples will be collected, preserved, and shipped in accordance with the Surface Water Ambient Monitoring Program (SWAMP) 2008 Quality Assurance Program Plan (QAPrP). Only personnel trained in proper water quality sampling will collect samples.

SWPPP.docx Page 700-3

07/22/2021

Upstream samples will be collected to represent the condition of the water body upgradient of the construction site. Downstream samples will be collected to represent the water body mixed with direct flow from the construction site. Samples will not be collected directly from ponded, sluggish, or stagnant water.

Upstream and downstream samples will be collected using one of the following methods:

• Placing a sample bottle directly into the stream flow in or near the main current upstream of sampling personnel, and allowing the sample bottle to fill completely;

OR,

• Placing a decontaminated or ‘sterile’ bailer or other ‘sterile’ collection device in or near the main current to collect the sample, and then transferring the collected water to appropriate sample bottles, allowing the sample bottles to fill completely.

Run-on samples, if applicable, will be collected to identify potential sedimentation/siltation and/or turbidity that originates off the project site and contributes to direct discharges from the construction site to the 303(d) listed water body. Run-on samples will be collected downgradient and within close proximity of the point of run-on to the project by pooling or ponding water and allowing the ponded water to spill over into sample bottles directly in the stream of water.

To maintain sample integrity and prevent cross-contamination, sampling collection personnel will:

• Wear a clean pair of surgical gloves prior to the collection and handling of each sample at each location.

• Use laboratory-provided sample containers (for laboratory analysis samples).

• Never sample near a running vehicle.

• Not park vehicles in the immediate sample collection area (even non-running vehicles).

• Not contaminate the inside of the sample bottle by not allowing it to come into contact with any material other than the water sample.

• Discard sample bottles or sample lids that have been dropped onto the ground prior to sample collection.

• Not leave the cooler lid open for an extended period of time once samples are placed inside.

• Not touch the exposed end of a sampling tube, if applicable.

• Avoid allowing rainwater to drip from rain gear or other surfaces into sample bottles.

SWPPP.docx Page 700-4

07/22/2021

• Not eat, smoke, or drink during sample collection.

• Not breathe, sneeze, or cough in the direction of an open sample bottle or container.

• Minimize the exposure of the samples to direct sunlight, as sunlight may cause biochemical transformation of the sample to take place.

• Decontaminate sampling equipment prior to sample collection using a TSP-soapy water wash, distilled water rinse, and final rinse with distilled water.

• Dispose of decontamination water/soaps appropriately; i.e., not discharge to the storm drain system or receiving water.

700.3.3 Sample Handling Procedures

Immediately following collection, sample bottles for laboratory analytical testing will be capped, labeled, documented on a Chain of Custody (COC) form provided by the analytical laboratory, sealed in a re-sealable plastic storage bag, placed in an ice-chilled cooler, at as near to 4 degrees Celsius as practicable, and delivered within 24 hours to the following California state-certified laboratory:

Laboratory Name: Alpha Analytical Laboratories, Inc

Address: 2722 Loker Avenue, West Suite A, Carlsbad, CA 92010

Telephone Number: 760.930.2555

Immediately following collection, samples for field analysis will be tested in accordance with the field instrument manufacturer’s instructions and results recorded on the Visual Inspection Field Log Sheet in Attachment Q.

700.3.4 Sample Documentation Procedures

All original data documented on sample bottle identification labels, Chain of Custody forms, Visual Inspection Field Log Sheets, and Inspection Checklists will be recorded using waterproof ink. These will be considered accountable documents. If an error is made on an accountable document, the individual will make corrections by lining through the error and entering the correct information. The erroneous information will not be obliterated. All corrections will be initialed and dated. Copies of the Visual Inspection Field Log Sheet and Chain of Custody form are provided in Attachment Q.
