Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility requesting renewal of existing NDPES Permit . Facility has existing wasteflow of 0.002
MGD, expansion flow of 0.200 MGD has been permitted, however no ATC has been issued Last
WLA done in 3/89 had secondary limits @ 0.002 and BPJ limits @ 0.200 MGD. Per Lake Wylie
Management Plan, @ 0.200 MGD, facility will have to meet Total P limit of 0.5 mg/l and Total N
limit of 4 mg/l (summer) and 8 mg/l (winter)
