Subject: Notice of Violation/Notice of Intent to Enforce - (NOV-2019-PC-0062)
Compliance Evaluation Inspection
Briarwood Subdivision WWTP
Permit No. NC0028746
Stokes County
Dear Mr. Becker:
A Compliance Evaluation Inspection was performed by Division of Water Resources, Winston
Salem Regional Office (WSRO), staff person Justin Henderson, on February 1, 2019. Mr. Sammy
Pegram, Back-up Operator in Responsible Charge (ORC), was present for this inspection. This
type of inspection consists of two basic parts: an in-office review of the facility files and self-
monitoring data and an on-site inspection of the facility. This inspection reflects non-compliance
with Permit No.NC0028746;the following violations require your immediate attention and action:
1) Discharge of floating solids in greater than trace amounts.Permit Condition Part I. (A.)
(1) states there shall be no discharge of floating solids or visible foam in other than trace
amounts.
2) Failure to maintain acceptable housekeeping of the facility. A significant amount of
leaf accumulation was observed throughout the facility, and also within several of the
facility's treatment units. Permit Condition Part II. Section (C.) (2) Proper Operation and
Maintenance, requires the Permittee to maintain all facilities and systems of treatment and
control which are installed or used by the Permittee to achieve compliance with the
conditions of the subject permit.
3) Failure to appropriately manage the facility's solids/sludge levels present within the
treatment units. An excessive amount of solids/sludge accumulation was observed in the
facility's clarifier's, chlorinator, chlorine contact chamber, de-chlorinator, and "effluent

g
Condition Part II. Section (C.) (2) Proper Operation and Maintenance, requires the
Permittee to properly operate all facilities and system of treatment and control which are
installed or used by the Permittee to achieve compliance with the conditions of the subject
permit.
This is a repeat violation that was previously documented in a Notice of Violation, dated
October 30, 2017.
4) Failure to perform representative sampling. During this inspection, the Back-up ORC
admitted that the composite sampler's effluent storage vessel is not thoroughly mixed prior
to aliquoting the sample for the required effluent parameter analyses.Permit Condition Part
II. Section (D.) (1.) Representative Sampling, requires samples collected to be
representative of the permitted discharge.
The occurrence of this violation provides an explanation for why the facility's effluent
Total Suspended Solids (TSS) analysis results, are not representative of the solids/sludge
levels observed in the plant at the time of this inspection.
5) Failure to obtain an Authorization to Construct (AtC) permit, prior to construction
of wastewater treatment facilities. The facility's addition of a manual bar screen to the
treatment operations constitutes a violation of Permit Condition Part III. Section (A.) (a.)
which states the Permittee shall not commence construction of wastewater treatment
facilities, nor add to the plant's treatment capacity, nor change the treatment process(es)
utilized at the treatment plant unless the Division has issued an AtC permit.
This is a repeat violation that was previously documented in a Notice of Violation, dated
October 30, 2017, in which the Permittee was instructed to apply for Permit Modification
to request approval of the bar screen.
To date,the Division has yet to receive a permit modification request to resolve this matter.
Along with the above described violations, the following items of concern also require your
attention:
a) Secondary containers, being utilized for calibration standard storage, must be labeled with
the standard's lot number and expiration date at a minimum.
b) The Back-up ORC was unable to provide a description of the composite sampler's
operations, during the compositing period. Please submit a written description of this
process to demonstrate compliance with Permit Condition Part II. Composite Sample,
which requires flow proportional sample collection.
Please submit a written plan,detailing the corrective actions to be implemented and expected dates
of resolution for the violations described in this Notice. Your written response plan shall be
submitted within 15 days following receipt of this Notice. The written response shall also include
the following information:
1) An explanation for why aeration has been added to the influent sedimentation chamber,
which clearly impedes settling of solids.
2) An explanation for why the surface skimmer, associated with Clarifier #1, discharges to
the aeration basin as opposed to the digestor.
Our office is considering the pursuit of punitive sanctions for these violations. Pursuant to
G.S. 143-215.6A, a civil penalty of not more than twenty-five thousand dollars ($25,000.00) may
be assessed against any person who violates or fails to act in accordance with the terms,conditions,
or requirements of any permit issued pursuant to G.S. 143-215.1. If no response is received in
this Office within the 15-day period, a civil penalty assessment may be prepared.
An unannounced follow-up inspection will be conducted, within 90-days of the date of this
correspondence, to evaluate your response to this Notice. Please be advised that these violations,
and any future violations are subject to civil penalty assessment of up to $25,000 per day, per
violation under authority of G.S. 143-215. Your timely action and attention to these matters is
appreciated. If you have any questions concerning this Notice, please contact Justin Henderson or
me at(336) 776-9800.
Sincerely,
