Subject: Relief from Monthly Monitoring
NPDES Stormwater Permit NCG030000
Certificate of Coverage # NCG030617
11707 Steele Creek Road,
Mecklenburg County, North Carolina
Director
We received a request for relief from monthly monitoring regarding levels of zinc and copper in stormwater
from this site exceeding the benchmark limits of the NCG030000 general permit. The facility was inspected on
September 28, 2016 by staff of this office accompanied by Ms. Lanette Plyler.
Based on our inspection and the investigation of potential sources are not attributed by CoaLogix SCR -Tech,
and Division is granting regulatory relief from the Tier Two response for copper and zinc benchmark exceedances.
Upon receipt of this letter, the subject facility may continue the semi-annual analytical monitoring schedule as
specified in the general permit for the remainder of the current permit term. Your current permit is set to expire on
October 31, 2017. Please note that this monitoring relief applies only to zinc and copper. Any benchmark limit
exceedance of other parameters required by the permit will trigger the tiered response actions as described within
the general permit.
You must notify this office, in writing, within 5 business days if you become aware of any other significant
source of copper or zinc at your facility that has potential to affect stormwater from the facility. The relief granted
in this letter is contingent upon the current practices at this facility. If any practices should deviate from current
activities and create significant stormwater exposure risk, this office reserves the right to withdraw this decision and
reinstate the permit specified tiered response that may be warranted by any new circumstances.

Inspection Summary:
This inspection was conducted per request for technical assistance from Lanette Plyler. In November of 2015, analytical
monitoring resulted in copper and zinc levels exceeding the benchmark limits specified in the general permit for
NCG030000. These exceedances put Coalogix in Tier Two monitoring and monthly analytical monitoring began in
December of 2015. After investigation, Coalogix was unable to locate the source causing the stormwater to exceed the
benchmark limits.
During our inspection, we found that the site was well maintained and we were unable to locate the source of the copper
and zinc causing exeeedances in the analytical monitoring. Because site conditions reflect compliance with all stipulations
of general permit NCG030000, this site may return to Tier One montioring requirements.

Rob Krebs, Mooresville Regional Office:
Please review the attached N01 application with the objective of responding to me with a recommendation to issue the
permit. I recognize that you may not visit each new permittee during this NOI review, but it affords you the opportunity
to log the permit into your regional database and add the facility to a future monitoring and compliance visit schedule.
Therefore, your recommendation now to issue the permit serves as your acknowledgement that (1) the facility is located
in your region, (2) that there are no current complaints outstanding about the facility that have not been dealt with, and
(3) that the facility may ultimately be inspected by the regional staff. I've also attached a scanned copy of the NOI and a
location map for your review.

I'd appreciate it, so I can issue their COC. I cannot issue the permit until the respective regional office reviews and
comments back to me with a recommendation to issue the permit.
Thanks.
