DIVISION OF ENVIRONMENTAL MANAGEMENT
F-hruar.y 28, 1989
MEMORANDUM
TO: Arthur Mouberry
FROM: Trevor Clements6�C'
SUBJECT: Best Professional Judgement (BPJ) Effluent Limits
for Direct Dischargers to Lake Wylie
Effective immediately, the Technical Support Unit will begin
implementation of a new wasteload allocation strategy for direct
dischargers into Lake Wylie.' As detailed in the February 17 memo-
randum to the Water Quality Section Chief, we are recommending
rest professional judgement (BPJ) effluent _limits to help curb the
impact of these point sources on water quality in Lake Wylie.
Based upon my discussion with the Water Quality Section
Chief, the following BPJ effluent limits will be routinely applied
to proposed dischargers and existing dischargers seeking expansion
that directly discharge into Lake Wylie:
BOD5 = 15 mg/l
NH3-N = 4 mg/1
DO 5 mg/l
These limits will apply unless it is found that protection of
water quality necessitates more stringent effluent limitations.
In addition, the following condition will be recommended for
all NPDES permits for direct discharges to Lake Wylie: "Division
Statement of Concern - Advanced levels of eutrophication have been
observed in Lake Wylie by the States of North and South Carolina.
In recognition of this problem, the Division will reserve the
right to reopen the permit to add effluent nutrient limits upon
designation of Lake Wylie as Nutrient Sensitive Waters (NSW) or if
deemed appropriate by the Division (or Environmental Management
Commission) based upon further water quality analyses."
Please feel free to contact me if there are any questions
concerning this matter.
