STORMIWATER PER(t';s` s "i ING
On June 26, 2019, NCDEQ staff inspected the subject facility for compliance with
Stormwater General Permit NCG140000. Please see the attached inspection report.
As a result of the site inspection, the following permit violations are noted:
1) Part IV, Section A: Stormwater Discharges - Analytical Monitoring Requirements
a) The benchmark limitation of between 6 and 9 for pH was exceeded at outlet #1 with a
result of 9.1 and at outlet #2 with a result of 10.1. The permittee failed to conduct a Tier
One response for pH. The benchmark values are not enforceable permit limits. An
exceedance of a stormwater benchmark value is not a permit violation; however, failure to
respond to the exceedances as outlined in this permit is a violation of permit conditions.
b) The benchmark limitation of 100 mg/1 for TSS was exceeded at outlet 41 with a result
of 270 mg/l and at outlet #2 with a result of 420 mg/l. The permittee failed to conduct a
Tier One response for TSS. The benchmark values are not enforceable permit limits. An
exceedance of a stormwater benchmark value is not a permit violation; however, failure to
respond to the exceedances as outlined in this permit is a violation of permit conditions.

Accordingly, you are required to respond to this letter in writing within 15 calendar days of
