A. Prior to Project-related activities, a qualified biologist will conduct pre-construction surveys for dusky-footed woodrat (Neotoma fuscipes). Identified woodrat

17 | P a g e houses will be avoided to the maximum extent practicable. If houses are unavoidable, NPS will implement informal NPS protocol of dismantling of woodrat houses.

B. California Red Legged Frog:

1. Where feasible, downed wood slated for movement or in the travel path will be searched to remove and relocate any amphibians (excluding California red-legged frog). Worker and visitor safety is a preeminent concern and searching for and relocating amphibians will not be conducted in instances where safety might be threatened.

2. To prevent inadvertent entrapment of California red-legged frog during construction, steep-walled holes, or trenches more than two (2) feet deep will be covered at the close of each working day by plywood or similar materials. If this is infeasible, one or more escape ramps will be installed. Before such holes or trenches are filled, they will be thoroughly inspected for trapped animals.

3. Any erosion control materials used shall not entrap animals. Jute mesh, loose, open weave textile fiber netting, burlap or non-binded materials (e.g., rice straw) shall be used for erosion control or other purposes. Tightly woven fabric such as jute should have mesh size <1 cm while loosely woven materials be >6 cm to avoid entrapment. No plastic mono-filament matting shall be used for erosion control.

4. If a work site is to be temporarily dewatered by pumping, intakes shall be completely screened with wire mesh not larger than five millimeters to prevent California red- legged frogs from entering the pump system. Water shall be released or discharged in accordance with the SWPPP.

5. Uneaten human food and trash attracts crows, ravens, coyotes, and other predators of the California red-legged frog. A litter control program will be instituted at each project site. All workers will ensure their food scraps, paper wrappers, food containers, cans, bottles, and other trash are deposited in covered or closed trash containers. The trash containers will be removed from the project site at the end of each working day.

6. To the maximum extent practicable, no construction activities will occur during rain events or within twenty-four (24) hours following a rain event. Prior to construction activities resuming, a Service-approved biologist will inspect the action area and all equipment/materials for the presence of California red-legged frogs. The animals will be allowed to move away from the project site of their own volition or moved by the Service-approved biologist.

C. Tree Protection:

1. Do not damage any existing tree with equipment or by attaching anything to the three.

2. Within the driplines of Redwoods and Oak trees roots greater than 1" in diameter may not be damaged.

3. All other roots 1" or greater shall be avoided where possible.

4. No tall coniferous trees greater than 18 inches in diameter at breast height or trees with large deformities or cavities shall be removed.

5. Native trees greater than 10 inches at breast height shall be avoided to the greatest extent practical.

18 | P a g e

6. Trees to be removed shall be identified as soon as possible but notification to the COR shall occur no later than 30-days prior to the planned removal.

D. Invasive Species Management:

1. All boots, equipment and tools must be disinfected using a ten percent (10%) bleach solution, seventy percent (70%) isopropyl alcohol, or other NPS approved disinfectant method prior to entering the site.

SECTION 01 57 23

STORM WATER POLLUTION PREVENTION

PART 1 - GENERAL

1.1 SUMMARY

A. Federal Regulations for controlling discharges of pollutants (including chemicals, erodible material, and trash) from municipal separate storm sewer systems, construction sites, and industrial activities, were brought under the National Pollution Discharge Elimination System (NPDES) permit process by amendments to the Clean Water Act (CWA), and promulgation of federal stormwater regulations issued by the U.S.

Environmental Protection Agency (USEPA). The USEPA uses the amount of ground disturbance as a measure of a project potential to generate pollution from erosion.

NPDES Phase I regulates discharges from construction sites that disturb five (5) acres or more. NPDES Phase II regulations expand the existing General Permit requirements under Phase I to include/regulated discharges from construction sites that disturb land equal to or greater than one (1) acre and less than five (5) acres, known as Small Construction Activity. Construction disturbances one (1) acre and above typically require a formal NPDES permit and a formal Stormwater Pollution Prevention Plan (SWPPP) must be submitted to the Authority Having Jurisdiction (AHJ) for review and approval.

B. The work of this section consists of implementing measures to prevent discharges of pollutants, including temporary storm water pollution during construction activities, through compliance with the California Construction General Permit for Stormwater.

C. All erosion control measures, both temporary and final, shall comply with the 2012

CASQA Construction BMP Handbook, the National Park Service - Golden Gate National Recreation Area 2010 BMP Handbook, and the project SWPPP.

D. This project will be managed as Risk Level 2 under the requirements of the California

Construction General Permit for Stormwater and the project SWPPP.

E. For this project the Park will provide the SWPPP for implementation by the Contractor.

Contractor will be required to respond to the QSD and COR when requesting action in line with the SWPPP. Contractor shall provide daily inspections per the Section 3.2 of this specification section.
