LINED ASH LANDFILL
The lined ash landfill, referred to as Area 3, is used to dispose of the ash that is produced by the Energy Resource Recovery Facility.
The 26 acre site is split into two 13-acre sections. The white cover is a special rain cap that is used before waste is placed. It simply conveys clean rain water away from the leachate collection system underneath the landfill.
The landfill was repermitted in 1994 to allow construction of a Subtitle D type liner system for waste placement. Referred to as the Area 3 Ash Landfill, the site is primarily designated for ash placement, but may accept municipal solid waste in the event of an emergency at the Energy Resource Recovery Facility.
The ash unit is designed in four phases - Phase 1 was placed into service in 1995 and totals 26 acres. The Area 3 Unit will encompass 100 acres when completed, and capacity is expected to be available for ash through 2015. The first phase construction costs were over $10 million.
The Area 3 Unit is underlaid with a clay/high density polyethylene (HDPE) composite liner, with an extra HDPE liner and leak detection system above the bottom liner as an extra means of environmental protection.

As of December 2000, almost all 26 acres of the Area 3 Lined Landfill had been filled.
The landfill holds a Permit No. 103 for operation, issued by the Virginia Department of Environmental Quality.
