3.1 IMPORT OF MATERIALS

A. Sources of rock, sand, gravel, earth, soil, or other imported natural material will be inspected for invasive non-native plants prior to acceptance. The contractor shall submit to the NPS Contracting

Officer a list of proposed sources for import materials 30 calendar days in advance of importing material. The list shall also include the end use and any temporary storage requirements of those materials. A list of pre-approved preferred material sources may be obtained from Yosemite

National Park. NPS Natural Resources staff would inspect sources of materials that pose a risk, either by their end use or storage requirements, of allowing invasive non-native plants (also known as noxious weeds) to establish in the park. Materials may be rejected if non-native invasive plants are present at the source and seeds could be present in the material. At the discretion of the

NPS Contracting Officer, potentially contaminated materials may be accepted if mitigating measures are implemented. Mitigation might include stripping the top 12 inches of source material, requiring fresh material stored less than 1 month, or sterilizing the material.

Contaminated materials that contain fines and have an end-use on the surface would require sterilization before importing to the park. Import material shall be shipped directly from the source to the park without intermediary storage or staging. Shipping vessels shall be covered to prevent spillage or blowing of their contents while in transit. Materials must also be transported and stored such that they would not acquire invasive non-native plant seeds from adjacent vegetation.

3.2 PROTECTION INSTALLATION

A. Provide temporary work limit fencing, tree trunk wrap, and tree barricades to protect existing trees, plants and critical root zones as directed by the Contracting Officer. Protections shall be in place before any excavation work or heavy equipment is allowed on site.

The Contractor shall notify the Construction manager at least five work days (not including weekends) prior to bringing any equipment into the Park. Equipment found to have entered the Park with potential contaminants will be removed from the Park at the direction of the Contracting Officer at Contractor's sole expense.

B. Minimize ground disturbance to the greatest extent possible.

C. The contractor shall get approval in writing from the Contracting Officer for fill material that must be used in a way or stored in a location not clearly specified in the contract.

D. Fill materials used within the top 8 inches of finished grade are required to be free of exotic and noxious weed species and shall have the source locations approved by the Contracting Officer.

The Contractor shall submit to the Contracting Officer a list of proposed sources for imported fill materials requiring certification 30 calendar days in advance of importing material. Any and all imported fill material must come from an NPS approved location. The presence of noxious weed species is grounds for rejection of the source. If exotic weed species are found or suspected, the Contractor may be required to strip the top 12 inches of source material and only import sub-surface material and/or sterilize the material, at the Contracting Officer's discretion.

The presence of the following particularly noxious weed species are grounds for rejection of the source: spotted knapweed, yellow star-thistle, perennial pepperweed, broom species, and other species on the California State List of Noxious Weeds. If spraying is required, the Contractor shall provide a licensed operator to spray according to applicable state regulations. The

Contractor shall not spray any herbicides until approved in writing by the Contracting Officer.

3.9 PROTECTION FROM EXOTIC ANIMALS

A. Drain and flush all pumps, tanks, live wells, buckets and other containers that might carry water contaminated with exotic animals, such as the zebra mussel, prior to bringing equipment into the park. Thoroughly wash all hauling tanks and equipment using a hard spray from a garden hose.

If equipment was used in infested waters, use the following steps to clean the equipment.

1. Wash with hot water (140 F or 40 C) or a high pressure washer (250 pounds per square inch). Remove all aquatic weeds -- they can carry zebra mussels.

PROTECTION

2. Disinfect equipment. Recent research shows that disinfection of nets and equipment with benzalkonium chloride at typical treatment rates (10 milligrams per liter for 24 hours, 100 milligrams per liter for 3 hours, or 250 milligrams per liter for 15 minutes) will effectively eliminate most exotic animals. Two other commonly used disinfectants, calcium hypochlorite and iodine, are ineffective against zebra mussels.

3. Adult zebra mussels can live more than a week out of water in moist, shaded areas. Dry pumps, nets and other equipment used in infested waters in the sun for two to four days after cleaning. If adult mussels are present, dry equipment for two weeks.
