Environmental Assessment for Closure of Cesspools and Implementation of Wastewater Management and Treatment Measures at Bellows Air Force Station, Hawaii.

摘要

The USAF has prepared this Environmental Assessment (EA) to assess the potential environmental effects that may result from closing 29 existing cesspools and installing 26 regulatory compliant wastewater treatment systems at existing cabins. Three action alternatives and a No Action Alternative were considered in this EA. The action alternatives include the following: (1) installation of onsite aerobic treatment units (ATU), dispose of treated effluent using subsurface drip lines and plant native Hawaiian vegetation above the driplines (2) installation of ATUs and convert the LCCs to seepage pits for disposal of treated effluent, and (3) install ATUs and store treated effluent in wastewater holding tanks for approved re-use options.
