Dredging of sediment pond & contact pool

The USGS Eastern Ecological Science Center seeks dredging of Settling Pond 3 and removal of sediment from a chlorine contact tank, with proposals due September 8 at 10:00 a.m. Mountain Time. This is a 100% Small Business Set Aside acquisition; the incumbent contractor is not named.

Place of performance is Jefferson County, West Virginia. The dredging work includes removal of approximately 6,400 tons of sediment from Pond 3 (approximately 75 feet wide by 375 feet long, originally 3 to 5 feet deep) to restore original depth, and removal of leaf debris and sediment from an approximately 18-foot by 18-foot by 6-foot chlorine contact tank. The sediment has been tested and determined safe for land application; the facility will designate an onsite disposal location. Hydraulic dredging with supernatant discharge back into the pond is not permitted without prior state Department of Environmental Protection approval; mechanical excavation with temporary isolation of the active influent stream is permissible. Construction is limited to 7:00 a.m. to 4:00 p.m., Monday through Friday, and requires Facility Manager approval of the schedule prior to commencement.
