FROM: Jim Rei-
ARO
SUBJECT: DMRs & BIMS
JUN 2 4 2003
For the month of April 2003, BIMS showed monitoring violations for the
Town of Valdese (mercury, Hg) and Huffman Finishing Company (silver, Ag).
The Town of Valdese's permit does not contain a testing requirement for
mercury, and despite there not being a testing requirement, the Town did
report a result for mercury in April 2003. See attached copies of
Valdese's permit and monitoring report.
For Huffman Finishing Company, the monitoring requirement for silver is
contradictory. See attached copies of the facility's permit and
monitoring report for April 2003.
Your attention to this matter is appreciated.

Subject: Issuance of NPDES Permit NCO025135
t (JC7' Huffman Finishing, Inc.
w Caldwell County
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as subsequently amended.) The
following modifications have been made to the permit:
• The antimony limit of 1.46 mg/L has been deleted based on data submitted. No values exceeded the allowable
concentration and reasonable potential analysis (RPA) calculated that the maximum predicted values were less
than the allowable concentration. The final permit contains quarterly monitoring only (no limit) for antimony.
• Silver monitoring has been modified t instead of monthly. Effluent data showed all values below
detection level and RPA calculated a e maximum predicted value was less than the allowable
concentration.
• A_nickel limit of 261 Kg/L has been added to permit. Evaluation of effluent data showed most values below
detection level, however there was one reported value of 500 µg/L. A daily maximum limit of 261 µg/L has
been implemented to protect the receiving stream from acute toxicity effects. After twelve months of
• The existing quartetly acute toxicity test at 96% has been modified to a quarterly chronic toxicity test based on
a revised DWQ procedure for whole toxicity tests. The instream waste concentration for Huffman Finishing
is greater than 0.25% and DWQ now applies a chronic toxicity test for dischargers that meet that criterion.
The revised toxicity test will be a quarterly chronic test using Ceriodaphnia and the limit will be 0.96%. The
test months will remain March, June, September and December.
• BODS_ TSS_ COD. and sulfide limits were modified based on updated production data provided by the
pemtittee. Modified limits are as follows and are only slightly lower than the previous limits.
BODS = 65 pounds/day (monthly average);
BODS = 132 pounds/day (daily maximum)
TSS = 278 pounds/day (monthly average);
TSS = 565 pounds/day (daily maximum)
COD = 759 pounds/day (monthly average);
COD = 1548 pounds/day (daily maximum)
Sulfides = 2.5 pounds/day (monthly average);
Sulfides = 5.2 pounds/day (daily maximum)
