Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility requesting renewal of NPDES permit. Technical Support concurs with the
recommendation of the Mooresville RO that BPJ limits be applied for the renewal of Lake Norman
Woods. BPJ limits based on protection of WS classification of Lake Norman and ability of facility
to meet the limits.
