Subject: questions on WTPs and general permit
Bill,
The General Permit NCG590000 was signed and became effective on August 1, 2014!
NC0086762 Swann WTP—Mailed on July 2013. I don't anticipate any issues with this one qualifying for the General
Permit. It has never failed a WET test.
Joe Corporon is doing this permit renewal so you will have to contact him and ask if it can be issued as a General Permit
or not.
I have been assigned to do the permit renewals for the two below.
NC0086011 Neilson WTP—Mailed November 2013. We currently do not discharge from this permit but have
improvements planned and will start in the next 2-3 years.
A conventional WTP must demonstrate no potential for aquatic toxicity so unless they have performed three years of
toxicity testing it will have to remain under an individual permit.
NC0079821 Thomas WTP—Mailed November 2013. If you'll recall we discussed this one because it has had some issues
passing WET. This is the one that I suspected the polymer was the culprit. We have been able to discontinue the use of
the polymer without consequence on our effluent and since doing so we have passed all our WET tests,so there is hope
that this plant is moving in the right direction.
This facility has failed too many times; it will be maintained as an individual permit. Hopefully,the discontinued use of
the polymer will make a difference and it can be issued as a General Permit with the renewal after this one.
