2. Curb Stop Valve Assembly (Detail D): Install curb stop valve, PVC or HDPE transition tee, 1-1/2 inch or 3 inch PVC pipe riser, three slip-to-thread adapters, steel fence post, and PVC cap (do not glue). *Note change from drawing. Wrap and urethane coat any exposed HDPE steel fittings.

3. Hydrant Assembly (Detail G): Install hydrant, 90 degree stainless steel elbow, reducer, slip-to-thread adaptor, PVC or HDPE transition tee, wood fence post, sump gravel, and polyethylene sheeting. Attach hydrant solidly to post with two steel straps. Wrap each strap twice around post. Nail the first strap just below the hydrant head and the second strap 12 inches below the first. Provide 26 to 28 inches of clearance between hydrant outlet and original ground surface. Install flow control valve on hydrant outlet when required in Work Data Sheet. Wrap buried galvanized riser pipe and fittings with pipe wrap. Urethane coat any exposed wrapped HDPE steel fittings. Attach water quality sign by wrapping around post and securing each corner with a roofing nail or at least three wraps with approved tape (1 inch).

4. Pressure Reducing Valve Assembly (Detail C): Install valve, reducer, slip-to-thread adapter, PVC riser and cap, steel fence post, and PVC cap (do not glue). Wrap or urethane coat any exposed metal fittings. PVC pipe does not need to be insulated.

5. Storage Tank Assembly: Shall include loading, transporting, unloading, site preparation, setting the tank, installing, plumbing, and partially backfilling the government furnished 10,000 gallon fiberglass storage tank from the Miles City BLM wareyard to and at the pipeline site. The tank shall be approximately 10.5 ft. in diameter and approximately 18.5 ft. in length, with an access port, port for an overflow, secondary drain, inlet/outlet, and daylight drain. Storage tank is mounted on removable saddles for transporting, storing, and installing the tank. The saddles shall be returned to the BLM once the storage tank is properly installed to allow for the return to the fiberglass manufacture. Excavate the horizontal storage tank foundation to a depth of 5 ft below original ground. The tank excavation limits shall be 14. 5 ft. wide and 22.5 ft long. The excavation directly under the storage tank shall be a cradle for the tank at a depth of 5.5 ft. Line the excavated area with a gravel apron made of pit run gravel to the depth of 6 inches (approximately 6 cubic yards), see storage tank detail. Place the storage tank atop the gravel apron, within the natural support, 5 ft. below original ground. The tank inset shall be oriented to newly installed spur and connection, see drawings. The Contractor shall be responsible for supplying and installing an inlet/outlet with check and float valves, air vent, overflow, secondary drain with curb stop and riser (include wood post), and a daylight drain with screen as designated and shown on the storage tank detail. The storage tank shall be back filled and compacted at a 2:1 slope from the gravel apron to total bury depth of 8 ft. minimum, 3 ft above original ground. The backfill and gravel material shall be approved by the Contacting

Officer prior to installation.

6. Daylight Drain Assembly (Detail H): Tee into a curb stop valve assembly (Detail D).

CURRY COULEE & PASTURE 4 PIPELINES 02665-8

Install curb stop valve, PVC or HDPE transition tee, 1-1/2 inch or 3 inch PVC pipe riser, three slip-to-thread adapters, steel fence post, and PVC cap (do not glue). *Note change from drawing. Wrap and urethane coat any exposed HDPE steel fittings.

Transition into PVC pipe that slopes downhill with a minimum 2% slope and finished with a flow through cap screen to prevent the entrance of wildlife.

3.3 FIELD QUALITY CONTROL:

A. General: 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.

B. Testing Procedure: 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 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'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'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.

A. Units: Measurement for pipe shall be the number of linear ft. provided measured on the ground surface along the completed pipeline centerline. Pay items of the Schedule of Items

(SOI) shall include the cost per foot of only PVC or only HDPE pipe to be used for trenching pipe, the cost per foot of HDPE pipe only to be used for plowing pipe since PVC pipe shall not be plowed. Measurement for assemblies shall be the number of each type assembly provided and installed. PVC or HDPE pipe within or between parts of an assembly shall be included for payment under pipe when payment is provided in the

Schedule of Items (SOI) for that respective pipe type, size, and rating. Daylight drains from curb stops shall be paid for by the linear foot as measured along the ground surface over the completed utility. The cost of excavating, cutting into and "teeing" off of a pipeline will not be paid for separately, but will be considered to be a subsidiary obligation of the Contractor under other contract items or assemblies. Installation and hookup of storage tank shall be a

lump sum.

A. Payment: Prices and payment will be full compensation for the work described in this section. Payment will be based on the following pay items:
