Gunpowder Creek WWTP
Caldwell County
Dear Mr.,Bailey:
The City of Lenoir entered into a Special Order by Consent (SOC)WQ S13-002 with the
North Carolina Environmental Management Commission whereby operation of the City of Lenoir
Wastewater Treatment Plant (Gunpowder Creek WWTP) has been placed under interim effluent
limitations and an enforceable schedule while,the existing WWTP is being upgraded.
Under section 3 of the Special Order by Consent, the City of Lenoir was required to
comply with interim effluent limitations as set-forth in the Consent Order. The WWTP failed to
comply with the interim effluent limitations for Ammonia Nitrogen contained in "Attachment A" of
the Order for the month of August 2015. i
I
3
After carefulf,review of this matter, I have not found grounds for sufficient justification to
waive the stipulated penalty, therefore, and pursuant to section 3 of the Special Order by
Consent, a stipulated penalty in the amount of$750.00 for each Weekly Average violation and
$1,750.00 for each Monthly Average violation is now due for a-total of$4,000.00. -
Payment by certified check payable to the Department of Environmental Quality must
be submitted to the Department at the address given below within thirty (30) days from receipt
of this demand:

foreclose further penalties for any future or continuing violations, failure to meet deadline dates,
or interim effluent violations.

The Ammonia as N violations listed above were attributed to thepetroleumproduct(s)entering the plant, beginning i
in May 2015. Biomass enhancing nutrients were continued to be added to all the SBR tanks. Thel first two weeks
of August(first week already reported on July DMR)were non-compliant for Ammonia. The middle of the month
showed reduction of Ammonia levels to below SOC limits. ,Toward the end of August, more petroleum product
began to show up in the wet well. Apparently, residual product in the collection system was washed into the plant. 3
That product was dipped off the wet well on August 24. For that week, effluent Ammonia levels were-high, but the
following.week showed compliance,with reductions continuing into September. The four weekly averages for
.Ammonia in September(in order)were 12.25 mg/l,6.16 mg/I,4.43 mg/I and 1.34 mg/I. The monthly Ammonia 1
as N average for September was 4.96 mg/I. The plant is compliant.
