1. A breach, leakage, malfunction, or spill is observed;

01 57 23.00 41- 10 AM-01

2. The leak or spill has not been cleaned up before precipitation; and

3. There is the potential for discharge of non-visible pollutants to surface waters or drainage system.

c. Construction activities; such as application of fertilizer, pesticide, herbicide, methyl methacrylate concrete sealant, or non-pigmented curing compound; have occurred during precipitation or within 24 hours preceding precipitation, and have the potential to discharge pollutants to surface waters or drainage system.

d. Soil amendments, including soil stabilization products, with the potential to alter pH levels or contribute toxic pollutants to storm water runoff have been applied, and have the potential to discharge pollutants to surface waters or drainage system (unless independent test data are available that demonstrate acceptable concentrations of non-visible pollutants in the soil amendment).

e. Storm water runoff from an area contaminated by historical usage of the site has the potential to discharge pollutants to surface waters or drainage system.

Identify sampling locations for collecting downstream and control samples, and the reason for their selection. The control sampling location shall be selected so the sample does not come into contact with materials, wastes or areas associated with potential non-visible pollutants or disturbed soil areas. Show non-visible pollutant sampling locations on the WPCDs.

Identify in the SAP the analytical method to be used for downhill and control samples for potential non-visible pollutants on the project.

Samples to be analyzed by a laboratory shall be sampled, preserved, and analyzed by a State-certified laboratory in conformance with the requirements in 40 CFR 136, "Guidelines Establishing Test Procedures for the Analysis of Pollutants."

CSWRCB GO 2009-0009-DWQ:

Erosion Control Sediment Control Wind Erosion Control Tracking Control Non-Storm Water Management Waste Management and Materials Pollution Control Active Treatment System Plan (if needed)

Erosion control practices are the primary means of preventing storm water contamination and shall be implemented for all disturbed soil on the project site. Select a variety of erosion control measures to protect the soil surface and prevent soil particles from being detached by rainfall, flowing water, or wind. Consider covering disturbed area with mulch, temporary seeding, soil stabilizers and binders, and installing fiber rolls or blankets, temporary vegetation, and permanent seeding. The minimum erosion control BMPs required shall include, but are not limited to:

scheduling, preservation of existing vegetation, and a combination of at least two or more of the following: Hydraulic Mulch, Hydroseeding, Soil Binders, Straw Much, or Geotextiles and Mats, as required to meet the CSWRCB GO 2009-0009-DWQ requirements. Installation, maintenance and inspection details are listed in the appropriate CASQA CABMPHB BMP fact sheet as defined in paragraph Erosion Control BMPs.

Sediment Control BMPs are the secondary means of preventing storm water contamination. When erosion control techniques are ineffective, sediment control techniques shall be used to capture any soil that becomes eroded.

These practices shall be implemented to divert flows from exposed soils, temporarily store flows, or otherwise limit runoff and the discharge of pollutants from exposed areas of the site. Effective perimeter controls shall be established; consider installing silt fences or placing straw wattles below slopes. The minimum required sediment control BMPs shall include, but are not limited to: silt fences, fiber rolls, street sweeping and vacuuming, and storm drain inlet protection to ensure permit compliance. Installation, maintenance and inspection details are listed in the appropriate CASQA CABMPHB BMP fact sheet as defined in paragraph

01 57 23.00 41- 12 AM-01

Sediment Control BMPs.

The Wind Erosion Control BMP is the primary means of preventing or alleviating dust generated by construction activities. The Wind Erosion Control BMP shall be included in the SWPPP, BMP details are listed in the appropriate CASQA CABMPHB BMP fact sheet as defined in paragraph Wind Erosion Control.

Tracking Control BMPs prevent or reduce the tracking of sediment off-site by vehicles leaving the construction area. Attention to control tracking of sediment off-site is essential. At a minimum the Stabilized Construction Entrance/Exit BMPs shall be listed in the SWPPP as tracking control.

Installation, maintenance, and inspection details are listed in the appropriate CASQA CABMPHB BMP fact sheet as defined in paragraph Tracking Control BMPs.

Non-storm water management and material management BMPs are source control BMPs that prevent pollution by limiting or reducing potential pollutants at their source before they come in contact with storm water. The discharge of materials other than storm water and authorized non-storm water discharges is prohibited. Certain authorized non-storm water discharges may be necessary for the completion of construction activities. The following required non-storm water BMPs shall be included in the SWPPP:

illicit connection/discharge, vehicle and equipment cleaning, vehicle and equipment fueling, and vehicle and equipment maintenance. Installation, maintenance, and inspection details are listed in the appropriate CASQA CABMPHB BMP fact sheet as defined in paragraph Non-Storm Water Management BMPS. The following required waste management and materials pollution control BMPs shall be included in the SWPPP: material delivery and storage, material use, stockpile management, spill prevention and control, and sanitary/septic management. Installation, maintenance, and inspection details are listed in the appropriate CASQA CABMPHB BMP fact sheet as defined in paragraph Waste Management And Materials Pollution Control BMPS.

BMP fact sheets can be found at the CASQA website and shall be included as an appendix of the SWPPP. A BMP fact sheet is a short document that gives all the information about a particular BMP. Typically, each fact sheet design contains the following information: description and purpose, suitable application, limitations, implementation, costs, inspection and maintenance, and references. BMPs must be implemented, maintained, and inspected in accordance with the fact sheets and the CSWRCB GO 2009-0009-DWQ requirements.

Each BMP shall be documented in the SWPPP in both a narrative section and figures in the WPCDs. The SWPPP must indicate all BMPs to be implemented, where they will be located, and when they will be installed on the WPCDs.

In cases where information about BMP installation, implementation, and management are not available on the CASQA website or in CSWRCB GO 2009-0009-DWQ, the BMP specifications and manufacture instructions must be supplied in the SWPPP, or in a SWPPP amendment, for prior government approval.

The SWPPP shall include a discussion of the inspection and maintenance program for all BMPs as identified to be utilized throughout the entire duration of the project. A qualified person (QSP, or persons appropriately trained by the QSP) will be assigned the responsibility to conduct inspections. The name and telephone number of that person shall be listed in the SWPPP document.

01 57 23.00 41- 13 AM-01

Select temporary stabilization methods with a minimum longevity period to meet the duration of the project. The BMPs with long longevity will improve relative effectiveness. The guidelines for required longevity for temporary stabilization methods are detailed in Appendix F of the CASQA CABMPHB. Additionally, temporary stabilization methods shall be selected which are habitat sensitive, including, but not limited to:

biodegradable or photodegradable materials and materials compatible with existing vegetation.

1.4.2 Permit Registration Documents (PRDs)

An additional part of the compliance requirement includes electronic filing of Permit Registration Documents (PRDs) to the SWRCB's Storm water Multi-application and Report Tracking System (SMARTS). The Contractor will likely be assigned the role of "Data Submitter" in SMARTS, which includes entering (in suitable eletronic format) the following PRDs in SMARTS:

Secondary to fiber rolls, silt fences are temporary linear sediment barriers of permeable fabric designed to intercept and slow the flow of sediment-laden sheet flow runoff. Silt fences allow sediment to settle from runoff before water leaves the construction site. Silt fences must be properly trenched and keyed in for full effectiveness. Design and layout, materials and installation requirements are detailed in the CASQA CABMPHB fact sheets, which must be adhered to.

2.1.2.1.1 SEDIMENT BASIN

Install and maintain sediment basins as a sediment control BMP in accordance with the CASQA CABMPHB "Sediment Basin, SE-2" fact sheet.

Sediment basins, at a minimum, shall be used where sediment-laden water may enter the drainage system or watercourse. They shall be used in association with dikes, temporary channels, and pipes used to convey runoff from disturbed areas. Use sediment basins in conjunction with erosion control practices to reduce the amount of sediment flowing into the basin.

The QSP shall inspect the sediment basin prior to any likely forecasted rain event (as defined in the paragraph titled "Rain Event Action Plans (REAPs)"), daily during rain events, after rain events, and a minimum of once per week when a rain event is not likely. Accumulated sediment must be periodically removed in order to maintain BMP effectiveness. The QSP shall ensure the sediment is removed when sediment accumulation reaches one-half the designated sediment storage volume. The QSP shall ensure all standing storm water from the basins is removed within 72 hours after accumulation.

01 57 23.00 41- 17 AM-01

/netting. Fiber rolls must be properly trenched and staked for full effectiveness. When fiber rolls are placed at the toe and on the face of slopes, they intercept runoff, reduce its flow velocity, release the runoff as sheet flow, and provide removal of sediment from the runoff. By interrupting the length of a slope, fiber rolls can also reduce erosion.

Fiber rolls may also be used for inlet protection and as check dams under certain situations. When installing on a slope, the slope inclination controls the required spacing as detailed in the CASQA CABMPHB fact sheet, and the Risk Level 2 requirements in the General Permit (see paragraph MAINTENANCE, MONITORING AND INSPECTIONS), both of which must be adhered to.

2.1.2.3 STREET SWEEPING AND VACUUMING
