2.1.2. Remove all remaining fuel and clean out accumulated sludge from both UST 528-1 and

UST 649-1 and all associated piping. No estimates for remaining fuel, sludge amounts or lengths of piping are available for UST649-1 and UST 528-1. The size range for UST649-1 and UST 528-1 approximately 1000 to 1500 gallons.

2.1.3. All work must in accordance with Federal, State and local laws and regulations. See

2.2.2.1. (NDAC 33-24-08-62.1) Before permanent closure is completed, contractors, with approval of the government, must measure for the presence of a release where contamination is most likely to be present at the underground storage tank site.

2.2.2.1.1. Under direction of the government and before the USTs can be certified for closure, the ground surrounding each tank will have to be sampled and tested for the presence of contamination.

2.2.2.2. (NDAC 33-24-08-62.1) In selecting sample types, sample locations, and measurement methods , contractors, with approval of government, must consider the method of closure, the nature of the stored substance, the type of backfill , the depth to ground water , and other factors appropriate for identifying the presence of a release.

2.2.2.2.1. Sample methodology, location and type must be selected under direction of the government.

2.2.2.2.2. Sampling methodology must consider: method of closure, nature of the stored substance, type of backfill, depth of ground water as well as other factors in order to identify the presence of contaminated substances.

7.5. Drawings illustrating Sampling Sites: A drawing depicting the sampling points around each UTS shall be presented as a part of the Project Report.

7.6. Sampling Report of soil samples taken around USTs shall be included in the Project Report

8. PERMITS: The contractor shall obtain all applicable construction permits for this task order including, but not limited to, AF Form 103 Work Clearance Request, Confined Space Access Permit and utility prints for the work site, welding, burn permit, as well as any transportation permits or licenses required for the removal of hazardous materials.
