Stanly County, NC
Dear Mr. Allen:
On March 6, 2019, Roberto Scheller of this Office conducted a compliance inspection at
the subject facility. This inspection was conducted as a Compliance Evaluation Inspection (CEI)
to insure compliance with permit requirements and conditions.
It was noted during the subject inspection that the subject facility had numerous issues
related to maintenance of treatment equipment. Please be advised that in accordance with your
NPDES Permit NC0021628, Part II, Section C, Item 2. "Proper Operation and Maintenance", "The
Permittee shall at all times provide the operation and maintenance resources necessary to
operate the existing facilities at optimum efficiency." In order to achieve full compliance with the
permit condition noted above, the following must be completed:
• The #1 aeration basin clean -out project must be completed;
• Both surface aerators in #1 aeration basin returned to full operation;
• The #2 aeration basin surface aerator that was not functional during the inspection
must also be repaired and placed back in full operation;
• Bar screen at headworks must be repaired or replaced to ensure proper screening
and removal of debris prior to wastewater flow entering aeration basin.
You are requested to respond to this Notice, in writing, regarding the above noted
violations, within fifteen (15) days of receipt. The response should include all remedial actions
including the specific activities to prevent the recurrence of these violations. Failure to respond
and/or failure to resolve the violations could subject you to further action by the Division of Water
Resources.

Comment: It was noted that only one of two surface aerators were in ODeration at time of insDection
Solids were begining to settle -out in aeration basin. Only one of two aeration basins was in
operation at time of inspection. It was noted in the last compliance inspection, conducted on
October 24, 2017, that aeration basin was down for maintenance. 16 months have passed
and soilds in aeration basin have not been cleaned out.
Mechanical screen was not removing debris from waste stream. Sweeps on screw
conveyor are worn -off and bottom bearing worn-out rendering mechanical screen useless.
Mechanical screen was in manual bypass at time of inspection.
Grit removal system not opeating at time of inspection. The result of the barscreen and grit
removal equipment not being properly maintained has allowed solids to accumulate in
aeration basins.
