Dear Mr. Walter:
Division staff has confirmed that the subject Certificate of Coverage [issued under NPDES
General Permit NCG500000] is no longer required. Therefore, in accordance with your request,
CoC NCG500305 is rescinded, effective immediately.
If in the future your company wishes to discharge to the State's surface waters, you must first
apply for and receive a new NPDES permit. Discharge of wastewater without a valid NPDES
permit will subject the responsible party to a civil penalty of up to $25,000 per day.
If you have questions about this matter, please contact Charles Weaver of my staff at the
telephone number or address listed below.

Charles,
I noted that on their NOI. If you confirmed they are going to sanitary sewer,
rescind the permit.
Thanks for letting me know.
Shannon
Ps. I will get you a County contact list. We are switching around a little and will
wait till it is updated.

Shannon - this facility is in Mebane. They have connected to sanitary sewer. Mr.
Robert King and I spoke on the phone yesterday - he confirmed that they want to
rescind their CoC.
May I proceed?
Also, is there a county -by -county contact list for these sorts of questions. I'm
sorry if I've been asking the wrong people....
Thanks,

Subject: Rescission of NPDES General Permit
Permit Number NCG500367
Olympic Products
Guilford County
Dear Mr. Moose:
Alan W. Klimek P. E. Director
Division of Water Quality
Culmn H. Sullins, Deputy Director
Division of Water Quality
Reference is made to your recent request for rescission of the subject NPDES General Permit. In your
letter dated May 26, 2004, you stated the facility is no longer in operation. In accordance with your
request, NPDES General Permit NCG500367 is rescinded, effective immediately.
Please be advised that this permit rescission is based wholly upon your statement that the activities which
would require general permit coverage at the site have ceased or been eliminated. Division staff has not
visited the site to obtain independent verification. Operating a treatment facility, discharging wastewater
or discharging specific types of stormwater to waters of the State without a valid NPDES permit will
subject the responsible party to a civil penalty of up to $25,000 per day. Enforcement action will be
certain for persons that have voluntarily relinquished permit coverage when, in fact, continuing permit
coverage was necessary. If, in retrospect, you feel the site still requires permit coverage, you should notify
this office immediately. Furthermore, if in the future you wish to again discharge to the State's surface
waters, you must first apply for and receive a new NPDES permit.
If the facility is in the process of being sold, you will be performing a public service if you would inform
the new or prospective owners of their potential need for NPDES permit coverage.
If you have questions about this matter, please contact Karen Rust at [phone], extension 361 or
the Water Quality staff in our Winston-Salem Regional Office at [phone].

TC r Alan W. Klimek, P.E.
