On October 22, 2002, Mecklenburg County Land Use and Environmental Services Agency issued a Closure Letter for the closed and unlined Phase I Area.

The Permit to Operate (PTO) for Phases 1, 2 and 3 of Expansion Area II were issued in 2006, and operations in this Area are ongoing. A Permit to Operate (PTO) was issued in 2012 for operations occurring in the Infill Expansion that connects Expansion Areas I and II, with a footprint area of 3.2 acres and the majority of capacity occurring as layover onto Expansion Areas I and II. Semiannual routine groundwater and surface water monitoring is currently being conducted at the Infill Area in accordance with 15A NCAC 13B .0544 and 15A NCAC 2L, and at the Phase I Area in accordance with 15A NCAC 13B .0503 and 15A NCAC 2L.

In addition, quarterly routine methane gas monitoring is currently being conducted at the Infill Area in accordance with 15A NCAC 13B .0544, and at the Phase I Area in accordance with 15A NCAC 13B .0503. During the July 2013 water quality monitoring event, concentrations of vinyl chloride (a volatile organic compound) first exceeded the regulatory North Carolina 2B Groundwater Standard within groundwater monitoring wells located at the Infill Area and the Phase I Area.
