Performance Work Statement Sediment Removal from the WTP Settling Pond Eielson AFB Alaska SECTION 1 Description of Services The Eielson AFB Water Treatment Plant uses six manganese oxide coated pressurized sand filters to remove the iron and manganese out of the bases drinking water. When the filters are backwashed, the backwash water is sent to a settling pond where the suspended matter settles out of the water. Over the years of backwashing the filters, there has been an accumulation of sediment in the settling pond which has reduced the depth to about 80% of its original capacity. The dimension of the pond is roughly 210 feet by 68 feet by 5 feet and has a capacity of approximately 306,000 gallons of water. The estimated amount of sediment accumulation is approximately two to three feet in the bottom of the settling pond, approximately 188,500 gallons, 800 cu. yards. The sediment is high in water content and must be de-watered to meet the requirement for no free liquids as determined by the "Paint Filter Liquids Test". The personnel at the Water Treatment Plant will collect a composite sample of the sediment and have it tested in accordance with the Toxicity Characteristic Leaching Procedure, test method 1311 as mentioned in 40 CFR 261.24 to ensure that the sediment is within the parameters for disposal. 1. SCOPE: Contractor shall provide all equipment, personnel, labor, and materials needed to perform sediment removal by using a suction dredge and use of a sludge press to obtain solids with no free liquid content as determined by the "Paint Filter Liquids Test". The Contractor shall also provide all equipment, personnel, labor, and materials needed to, load, transport and dispose of the sediment into Eielson's permitted land fill in the Quarry Hills area. The Contractor shall perform this work according to the following performance standards. 1.1. The settling pond has a gravel bottom; in the process of removing sediment the contractor shall disturb as little gravel as possible. 1.2. Removal of sediment should not interfere with the normal operation of the Water Treatment Plant. The plant will need to remain online during the operation and will need to have the ability to send backwash water to the settling pond for treatment. The contractor shall coordinate with Mr. Carter the WTP Supervisor at 907-377- 1449 or Mr. Hollowell, Water Systems Superintendent at 907-377-2264 as how this is to be accomplished. 1.3. During the course of work, the contractor should not interfere with the normal water flow of the settling pond or cause a situation that would lead to the water treatment plant violating their Wastewater Discharge Permit (#AKG380017), or any (ADEC) Alaska Department of Environmental Conservation or Air Force regulation. Run off or decanted water: Any and all water that comes out of the pond must go back into the pond. All work shall be done inside of water plant fenced in area; the area outside of the fence is a contaminated area. There shall be no work done on contaminated soil, and no equipment or vehicles parked on contaminated soil. Government will designate the area and mark the boundaries. Access to the site using the 'side gate' near the Garrison Slough pond outfall. Ground matting will be required to protect the grass and vegetation along the access route, from the paved road to the access gate. Small footprint is required. Any damage to the grass will be repaired by the contractor. 1.4. Transport dewatered sediment to the disposal site in vehicles or containers fitted with positive sealing devices. At a minimum, fit tailgates with a rubber seal, use additional tailgate locks, and cover the load with a securely fastened tarp. 1.5. Sediment disposal shall occur only within the designated disposal areas. Government will designate the area and mark the boundaries to ensure that the disposal area is within the location of one of the bases state permitted land fill in the Quarry Hill areas. 1.6. Clean accumulated sediment from transport trucks or vehicles within the confines of the disposal area immediately after depositing loads to prevent spillage and drag-out onto roadways. 1.7. Clean up area where the sediment was removed to ensure that no material is left behind and restore any grass or dirt areas that were damaged during the sediment removal process to their original state.
