SUBJECT: Comments on NPDES Permit for High Point Eastside WWTP
NPDES Permit No. NC0024210
Guilford County
030608
The nickel limit given in the recently issued High Point Eastside NPDES permit is
incorrect. Effluent concentrations of metals at this facility are being limited at the water
quality standard. However, I failed to change the limit for nickel from the old standard (50
µg/l) to the most recent standard of 88 µg/l. This was brought to my attention after Mr.
Bill Frazier, the ORC for this facility, questioned the limit given. (I did not call Mr.
Frazier.) If you have any questions, please advise.

Bill Frazier, the ORC with HighPoint Eastside, called. He has discovered errors in their
NPDES permit that was made effective January 1 (nice timing). The nickel limit is listed as
50 mg/l! Obvioiusly an error. Please have appropriate staff check into what it should be. At
lust I thought it was probably a typo (i.e., ug instead of mg), but the standard is 88 ug/l
now so this needs a close review. Also, Bill said the WWTP description was not accurate
and, if changes are made to the permit, he'd like that corrected. His number is
[phone]. (I told him that the permit writer would probably contact him to discuss
corrections)
