apron to total bury depth of 14 ft. minimum, 4 ft above original ground. The backfill and gravel material shall be approved by the Contacting Officer prior to installation.

1.1 FIELD QUALITY CONTROL:

A. General:

B. Testing (not anticipated within this contract): The pipeline may be tested as requested by the Contracting Officer Representative at the cost to the BLM. The Contractor shall prove pipeline integrity if lack of quality control or mishandling or poor installation has been observed during the installation of the pipeline. The Contractor shall make necessary accommodations if any tests are requested (no tests anticipated under this contract).

C. Testing Procedure (not anticipated within this contract): The pipeline may be tested in whole or in segments as work progresses. If the pipeline is connected to an existing system, the test shall apply to both systems. A 24 hour notice is required for conducting second and final tests. Test pressure shall be the maximum operating pressure as listed in the drawings. Fill pipeline with water and conduct test as follows:

1. First Test: The presence of the Contracting Officer Representative is not required at the first test. Pressurize to test pressure and inspect for failure criteria. Correct all defects and repeat the test until no further defects are observed.

2. Second Test: Once the first test has been conducted and all defects corrected, a second test shall be conducted in the Contracting Officer Representative 's presence. Pressurize to test pressure. Hold this pressure for a minimum of 4 hours and then inspect for failure criteria. Correct all defects and repeat the test until no further defects are observed and until test is approved. Backfilling may be completed after approval of second test.

3. Final Test: Once backfilling is complete a final test shall be conducted in the

Contracting Officer Representative's presence. Pressurize to test pressure.

Hold this pressure for a minimum of 24 hours and then inspect for failure criteria. Correct all defects and repeat the test until no further defects are observed and until test is approved.

SECTION 02910

A. Section Includes: All stripping, stockpiling, spreading, grading of topsoil. All preparation for seeding and seeding of restoration areas.

B. Permits: The Contractor shall obtain all necessary permits for this project (such as the DEQ Storm Water permits). The Contractor shall follow Federal and State rules for erosion controls.

PART 2: PRODUCTS

2.1 TOPSOIL:

A. Excavation of Topsoil: In areas of construction, topsoil will be stockpiled separately from other material, and be reused in reclamation of the disturbed areas. Remove all construction debris.

2.2 SEED MIXTURE:

A. There shall be no primary or secondary noxious weed seed in the seed mixture.

Seed shall be tested, and the viability testing of seed shall be done in accordance with State law(s) and within 6 months prior to purchase. Commercial seed shall be either certified or registered seed. The seed mixture container shall be tagged in accordance with State law(s) and available for inspection by the Contracting Officer Representative.

Seed shall be planted using a drill equipped with a depth regulator to ensure proper depth of planting where drilling is possible. The seed mixture shall be evenly and uniformly planted over the disturbed area. Smaller/heavier seeds have a tendency to drop to the bottom of the drill and are planted first. The holder shall take appropriate measures to insure this does not occur. Where drilling is not possible, seed shall be broadcast, and the area shall be raked or chained to cover the seed.

When broadcasting the seed, the pounds per acre noted below are to be doubled.

Use Attachment A in order to determine seed mixture for each area.
