1. The City of Greensboro previously operated the White Street Sanitary Landfill, Phase II as a
municipal solid waste landfill (MSWLF) unit under Permit 4103-MSWLF-1987. The
landfill was constructed without a liner below the waste. The landfill operation began in the
late 1970s. The unit ceased receiving waste in some areas prior to October 9, 1991. The
footprint of the filled areas was 135 acres. Forty-five (45) acres of this unit were
permanently closed and covered with two feet of soil in accordance with the permit. The
areal limit after October 9, 1991, and before October 9, 1993, was 90 acres.

2. A transition plan was approved for the unlined MSWLF unit (Phase II) in 1996. The plan
was revised in 1997 to include the construction and operation of a construction and
demolition solid waste landfill (C&DLF) unit over the closed unlined MSWLF unit.
Additional twenty- five (25) acres of the unlined MSWLF unit were permanently closed with
two feet of clay and six inches of soil. A vertical expansion over the closed unlined MSWLF
unit was permitted for construction and demolition (C&D) waste disposal with an area of 65
acres and maximum elevation of 872 feet above mean sea level.

3. In 2008, to comply with Rule 15A NCAC 13B .0547(4) the City of Greensboro requested an
approval for continued operations of the C&DLF unit on top of the closed unlined MSWLF
(Phase II).

4. In 2012, the 65-acre C&DLF unit on top of the closed unlined MSWLF (Phase II) has the
approved gross capacity of 2,525,443 cubic yards (CY), the City of Greensboro operates the
landfill by a filling plan based on a gross capacity of 2,370,000 CY for the landfill unit. The
