Attached is the letter from October 2021 granting NCG030139 relief. Both facilities mentioned have relief from
monthly monitoring for copper and zinc for the remainder of the permit term.
Benchmark exceedances do not need to be reported to the regional office for these two parameters, based upon
the referenced letters.
Contact me if you have questions.

Good Morning Mr.Garrow,
Upon doing some research and speaking with Core & Main (Permit#NCG030461), I believe that Mueller
should be considered exempt from the Tiered responses forth is permit term.
Core & Main is our lessee, and we share the property at 10210 Statesville Blvd with them. I have a letter
addressed to Core & Main from a Zahid S. Khan (Employee of NCDEQ) dated October 6, 2021, relieving
Core & Main from tiered responses for the duration of the permit.
Speaking to the team over at Core & Main, my understanding is that it was determined by a
representative from NCDEQ that Copper and Zinc were naturally occurring in the soil on this property,
which was enough to justify the relief from tiered responses related to those materials.
The letter I am referring to is attached to this email. Please review it and let us know if we can
discuss getting the same exemption applied to Mueller.
Thanks in advance,
Dillon Wilkie

Good afternoon,
am writing on behalf of Mueller Water Products located at 10210 Statesville Blvd., Cleveland, NC,
27013.
We received the results from our 3rd quarter quantitative stormwater sampling, and it was determined
that we had an exceedance of copper at outfall#2.
The samples were collected by our environmental consultant, One Environmental.
I've attached the lab results to this email.
We are actively investigating to determine any potential causes for this sudden exceedance and rectify
them as soon as possible.
We will be monitoring the outfall going forward and will pull a sample again this quarter.
Please let me know if you need anything else from us.
Thankyou,
Dillon Wilkie

Dear Mr. Small:
We are in receipt of your September 15, 2021 email requesting relief from monthly monitoring at the
Mueller Systems Cleveland plant. Based on past site inspections, including September 15, 2021,and email
correspondence regarding copper and zinc, the facility is in compliance with the tiered response actions and
other conditions of the NCG030139 Permit. Therefore,the Division is granting regulatory relief from the Tier
responses. Upon receipt of this letter, the subject facility may resume the permit specified quarterly analytical
monitoring for the remainder of the current permit term which expires on June 30, 2026. This decision applies
only to the copper and zinc benchmarks. A benchmark exceedance of any other parameter listed in your permit
will trigger the tiered response actions as described in the general permit.
You must notify this office, in writing, within five business days if you become aware of any other
significant source of copper or zinc at your facility that has the potential to be exposed to stormwater. The
relief granted in this letter is contingent upon the current industrial practices at the Mueller Systems Cleveland
plant. Please retain and append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit. If
you have any questions or comments concerning this letter,please contact me or James Moore at 704-663-1699.
Sincerely,
�D�oeluSlgned�yby,
