MEMORANDUM
TO. A. C. Turnage //�
FROM: Forrest Westall
SUBJECT: Effluent Limitations for a Proposed Elkin WWTP
I have reviewed the attached memo (1/9/81) from Fin Johnson and have
discussed this situation with others in the Winston Salem Regional Office.
Basedon the low total chromium levels presently in the Chatham Mfg.
discharge and with adequate monitoring requirements in the permit
(if granted), the deletion of the total chromium limit is acceptable.
If you agree, then the approval form can be modified. I would recommend
that Fin Johnson's memo and my memo be attached to the form as backup for
this change. If you have any questions, please let me know.

Regional Supervisor
SUBJECT: Waste Load Allocation for a combined
Town of Elkin and Chatham ::anufacturinr Company
treated waste discharge
Sorry County
Since the Town's Mi'."1' is desil;::ed for .11 11Cll (permitted at a 1. 1 itGD
level) and the Town is proposing, to pvrcliase the Chatham twlTp designed for
4.0 MGD (new permit drafted it a 2.9 :[CD level), it necessitated some thought
re&arding the limitations for i.nown inrlu;;trin; pollutant levels in the future
combined discharge.
There may he a problem with TSS proposed since the Chatham discharge
averages approximately 45 mg/l and the Elkin discharge averages approximately
27 mg/l. Oil and grease ling averaged 15 mg/l, total chromium has averaged
.08 mg/l, phenol has avernrred 14 ug/l, and sulfide .14 mg/1 in the Chatham
discharge during the period November, 1979 through October, 1980.
Since the levels of chromium, oil and greane, phenol, and sulfide have
been consistantly low, it nppears logical to merely require monitoring of each
in the effluent rather than to set limits at this point. The proposed 11.4
mg/l total chromium for the 4.0 MGD discharge should be deleted since it
doesn't reflect the established level of .08 mg/l (12 month average) by Chathemo
the Town's only known source of chromium bearing wnuee.
Therefore, we recommend deletion of the 11.4 ng/1 total chromium limit as
It would appear to encourage pollution and we agree with the other limits a'--0
