DIVISION OF ENVIRONMENTAL MANAGEMENT

January 25, 1979
MEMORANDUM
TO: William C. Mills
Permits and Engineering
FROM: Gary T. Tweed e�
Environmental Engineer
Asheville Regional Office
SUBJECT: NPDES Permit No. NC0004685
PPG Industries, Inc.
Cleveland County, North Carolina
On January 23, 1979, a meeting with PPG was held at the Asheville
Regional Office to discuss subject permit. The attached pages of the permit
have been modified reflecting changes agreed upon by PPG and the Asheville
Staff. Final lbs/day limitations are based on same concentrations as interim
limitations increased proportionally with increase in design flow. Example -
Interim BOD5 daily average limitation is 70 lbs/day based on 0.42 MGD which
computes to 20 mg/l. At final flow of 0.875 MGD and 20 mg/i BOD5 concentra-
tion lbs/day BOD5 is 146. Daily maximum limitations are based on same
concentrations at flow of 1.1 MGD.
It is recommended that this modification be issued to PPG. Should
.you have any questions, please advise.

NPDES Permit No. NC0004685
PPG Industries, Inc., at its Shelby Plant
(Works #52)
is hereby authorized to:
I. Enter into a contract for construction of wastewater treatment units
to be operated in conjunction with the existing 0.42 MGD treatment
plant which will result in a treatment system having a nominal
hydraulic capacity of 0.875 MGD, and
2. Construct and operate a 0.875 MGD wastewater treatment plant by
modifying an existing 0.42 MGD wastewater treatment plant which
will remain in operation until construction of the new facility
is completed, subject to Part III, condition No. C of this new
Permit, and
3. Discharge from said treatment works (OOI) into Brushy Creek which
is classified Class "C" in the Broad River Basin, and
4. Discharge storm water from the (002) sump during those times when
storm water entering the (002) sump exceeds plant trench wash
water needs into Overflow Branch which bears a Class "C" classi-
fication and is located in the Broad River Basin.
