Permittee: City of Kannapolis Waste Water Collection System
Permit No. WQCS00327
Cabarrus County

Dear Mr. Legg:

1. Mr. Tony Parker of the Mooresville Regional Office of the NC Division of Water
Resources (DWR or the Division) conducted a compliance evaluation inspection (CEI) of
the City’s wastewater collection system (WWCS) on August 6, 2020. The assistance of
Mr. Alex Anderson and Mr. Ed Sowell and others during the inspection was greatly
appreciated. A copy of the inspection report is attached for your records and inspection
findings are summarized below.

Site/System Review

2. The following system components were inspected:

a. Four pump stations were inspected.
b. Numerous manholes were inspected.
c. Several right of way was inspected.
d. One aerial crossing was inspected.

Please review the attached Report for additional details and items noted during this
inspection

3. As you are aware, owners of permitted collection systems must comply with their permit
and all rules listed under NC Administrative Code 15A NCAC 02T .0400, et seq. The
Town’s compliance status with each of these rules is summarized below:

a. 15A NCAC 02T .0403(a)(1): Requires that the system be effectively maintained
and operated at all times to prevent discharge to land or surface waters and any
contravention of ground or surface water standards.

Observations: Each pump station appeared to well maintained and operated,
however, grease was noted in high concentrations at 3 of the pump stations
inspected. More work needs to be done in this area.

Compliance Status: Compliant

b. 15A NCAC 02T .0403(a)(2): Requires that a map of the wastewater collection
system be developed and actively maintained.

Observations: The City utilizes a GIS mapping system and has various paper
maps and showing locations of lines, direction of flow, force mains, pump stations,
manholes and other information.

Compliance Status: Compliant

c. 15A NCAC 02T .0403(a)(3): Requires that an operation and maintenance (O&M)
plan be developed and implemented, which includes pump station inspection
frequency, preventative maintenance schedule, spare parts inventory and overflow
response.

Observations Pump station logs were available. Records were available for all
activities. Spare parts and pumps are kept in stock. An overflow response plan
was available.

Compliance Status: Compliant

d. 15A NCAC 02T .0403(a)(4): Requires that the permittee or its representative
inspect pump stations that are not connected to a telemetry system (i.e., remote
alarm system) every day (i.e., 365 days per year) and pump stations that are
connected to a telemetry system at least once per week.

Observations: The pump station inspection logs indicate that the pump stations
are visited as required.

Compliance Status: Compliant

e. 15A NCAC 02T .0403(a)(5): Requires that the permittee or its representative
inspect high-priority sewers (HPS - as defined in 15A NCAC 02T .0402(2)) at least
once every six months and document the inspections.

Observations: All lines are checked and documented.

Compliance Status: Compliant

f. 15A NCAC 02T .0403(a)(6): Requires that the permittee or its representative
conduct a general observation of the entire wastewater collection system at least
once per year and document same.

Compliance Status: Compliant.

g. 15A NCAC 02T .0403(a)(7): Requires that overflows and bypasses from the
system be reported to the Division's Mooresville Regional Office in accordance
with 15A NCAC 02B .0506(a), and that public notice must be provided as required
by G.S. 143-215.1C.

Observations: SSO’s have been reported with this system during this review
period. The NC regulations and statutes, which cover the reporting requirements
for SSOs, are found in NC Administrative Code 15A NCAC 02B .0506(a) and NC
General Statute 143-215.1C, respectively. You may access the NC regulations
online at the NC Office of Administrative Hearings (OAH) website at:
http://www.oah.state.nc.us/rules/ and the NC General Statutes online at the NC
General Assembly's website at:
http://www.ncga.state.nc.us/gascripts/Statutes/StatutesTOC.pl. You may wish to
review them to ensure you are fully familiar with all requirements.

When reporting SSOs to DWQ, you must call the Mooresville Regional Office
(MRO) at 704-663-1699 during normal business hours. If outside normal business
hours, you must report the spill to the NC Division of Emergency Management at
1-800-858-0368. Please note that all reportable SSOs must be reported within 24
hours of the occurrence, or first knowledge, of the SSO. Please also note that voice
mail or faxed messages are not considered as the initial verbal report. You must
talk to and report the spill to a live person.

Compliance Status: Compliant

h. 15A NCAC 02T .0403(a)(8): Requires that a grease control program be developed
and implemented as follows:

1. For publicly owned collection systems, the Grease Control Program shall
include at least bi-annual distribution of grease education materials to users
and the legal means to require grease interceptors. The Program shall also
include legal means for inspections, enforcement, and legal means to
control grease entering the system from other public and private satellite
sewer systems.

2. Grease education materials shall be distributed more often than required
above if necessary to prevent grease-related sanitary sewer overflows.

Observations: Educational materials are mailed out to all customers and the same
information is available upon request and is available at City offices and on line.

Compliance Status: Compliant.

i. 15A NCAC 02T .0403(a)(9): Requires that right-of-ways (ROW) and easements
be maintained to allow for personnel and equipment accessibility.

Observations: Records were reviewed documenting that the right-of-ways were
mowed, inspected and maintained to provide accessibility.

Compliance Status: Compliant.

j. 15A NCAC 02T .0403(a)(10): Requires that documentation be kept for all
activities you undertake to comply with the requirements of 15A NCAC 02T .0403,
subparagraphs (a)(1) through (a)(9), for a minimum of three years, with the
exception of the map, which shall be maintained for the life of the system.

Observations: Records were reviewed for right of way mowing, high-priority line
inspections, and observation of the entire system.

Compliance Status: Compliant

Inspection Date: 08/06/2020 Inspection Type : Collection System Inspect Non Sampling Reason for Visit: Routine
Inspection Summary:
This inspection revealed that the City is in compliance with their permit but some areas need improvement and are listed as
follows:
Grease control- Grease inspections may need to be increased due to SSO's and grease accumlation at the P/S's visited.
CIP - More details need to be provided in future plans.
SSO's - The City had multiple spills at reoccuring locations and there needs to be detailed plans in place to address this
issue in the future. This should also be in your CIP.
For the most part the City does a good job at O/M and with a little more attention to the above items could go a long way at
preventing the high number of SSO's and will show details of infastructure improvements and planning.
