Section 1: Introduction
This document satisfies the annual assessment and reporting requirement of Storm Water Permit
No. NCS000395 as follows:
• Evaluate program compliance, the appropriateness of best management practices
(BMPs), and progress towards achieving measurable goals; and
• Evaluate the performance and effectiveness of the Storm Water Quality Management
Program Plan, herein referred to as the Storm Water Plan.
Charlotte-Mecklenburg Storm Water Services (CMSWS) has developed and is maintaining the
Storm Water Plan for Permit No. NCS000395 on behalf of all co-permittees, including
Mecklenburg County, Charlotte-Mecklenburg Schools (CMS), Central Piedmont Community
College (CPCC), and the Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill, and
Pineville. This Storm Water Plan is available on the following website: http://storm
water.charmeck.org (select"Surface Water Quality," select"Program Overview," select
"Current Storm Water Management Plan"under Phase II Permit at the bottom of the page). The
purpose of the Storm Water Plan is to describe the actions undertaken by the Permittee to ensure
compliance with Permit requirements. Each of the six (6) minimum measures contained in the
Permit plus TMDL compliance (referred to as Programs) has a separate section in the Storm
Water Plan. Each section includes a Summary Table that describes the Best Management
Practices, referred to as BMPs, that will be undertaken to fulfill Permit requirements. These
BMPs include specific Measurable Goals that must be completed in accordance with established
schedules to ensure fulfillment of the BMP. Fulfillment of the BMPs equates to compliance with
the Storm Water Plan and Permit. The BMPs and Measurable Goals are described in detail
every year in a Work Plan with BMPs referred to as program elements and the Measurable Goals
referred to as tasks. The Work Plan Program Element Documentation Log (Log) is completed
by staff assigned the lead role in the fulfillment of program elements and assigned tasks. The
Logs serve to document the who, what, when, where, and how regarding tasks as they are
completed throughout the fiscal year. Various attachments, such as maps,presentations, data
tables, etc., are added to the Logs as necessary to ensure complete documentation of all activities
completed and data and information generated. These Logs and attachments are assessed and
approved by supervisors before they are loaded into the Cityworks database attached to an
Activity Report where they are available for access digitally. At the end of the fiscal year,
established Measures of Success as described in the Storm Water Plan are calculated and
assessed along with the assessment of Logs and associated attachments by the supervisors to
determine compliance with the Storm Water Plan and Permit. These assessments also serve as
the basis for identification of improvements to the Storm Water Plan, Work Plan and Measures
of Success to enhance efforts for Permit compliance, which are implemented during the next
fiscal year.
Section 2 of the annual report contained herein provides background information regarding the
implementation of the Storm Water Plan between July 1, 2022 and June 30, 2023 (FY2023),
including a fiscal analysis. Sections 3 through 9 provide an overview of the programs
implemented to fulfill Permit requirements, including BMP Summary Tables for the six (6)
minimum measures and TMDLs with Work Plan Codes, BMP Descriptions, Measurable Goals,
Schedules, and Activity Reports numbers from Cityworks that contain Logs with details

Program Manager at 980-314-3217 or rusty.rozzelle(a,mecklenburgcountync.gov. The BMP
Summary Tables also contain the numbers for Attachments provided at the end of this annual
report that include a summary of data and information accumulated throughout the reporting year
as well as lists of changes to the Storm Water Plan. Attachment 1 provides data generated from
countywide Phase II activities whereas Attachment 2 provides data from activities specific to
each Phase II jurisdictions. The remainder of the attachments include more detailed information
regarding specific countywide activities. Section 11 of this report provides an assessment of
compliance with the Storm Water Plan and Permit requirements, as well as the status of
attainment of the identified Measures of Success during FY2023. Section 12 concludes with a
summary of the status of Work Plan modifications for improving Permit compliance during
FY2023 and changes to be implemented in FY2024.

Section 2: Overview and Funding
CMSWS is responsible for developing, implementing, managing and overseeing the Storm
Water Plan under the direction of Mecklenburg County's Water Quality Program Manager. The
specific tasks, deadlines and assigned staff for fulfillment of the Storm Water Plan are described
in an annual Work Plan. A copy of this Work Plan is available upon request to Mecklenburg
County's Water Quality Program Manager at 980-314-3217 or
[e-mail]. As specified in the Permit, each co-permittee is
responsible for compliance with the terms and conditions of the Permit for storm water activities
and watershed specific requirements within their jurisdictional area. Appropriate legal authority
has been established by each jurisdiction for implementation of the Storm Water Plan through
the adoption of Surface Water Pollution Control Ordinances that prohibit illicit discharges to the
MS4 as well as the adoption of post-construction and erosion control ordinances. Mecklenburg
County is delegated authority by each jurisdiction to enforce these ordinances. The majority of
Permit compliance activities are performed by the Water Quality and Permitting and Compliance
Programs within CMSWS. Funding for implementation of these Programs is shared by each
jurisdiction based on an adopted Funding Strategy. Implementation costs for the reporting
period of July 1, 2022 through June 30, 2023 (FY2023) were $1,012,189.37, including
$708,982.13 and $219,949.53 in labor costs for the Water Quality and Permitting and
Compliance Programs, respectively, and $83,247.71 in operating costs for laboratory, equipment,
and supplies for the Water Quality Program. For FY2024, costs are estimated at $996,410.38,
including $892,014.24 in staff costs and $104,396.14 in operating costs. The Phase II
jurisdictions in Mecklenburg County utilize the revenue they receive from their storm water and
land development fees to fund the implementation of the Program with the exception of CMS
and CPCC, which do not receive revenue from the storm water fee and therefore fund Phase II
Program implementation through their general budget.

Section 3: Stormwater Management Program Administration
3.1 Program Overview
A program has been developed and is currently being implemented for administering the Phase II
Permit for Mecklenburg County's Phase II jurisdictions/entities for the purpose of ensuring that
all Permit requirements are effectively and efficiently fulfilled by co-permittees in accordance
with the Storm Water Plan and that the administration requirements specified in the Permit are
being met. The Program includes 37 separate BMPs and 190 Measurable Goals as described in
the eight(8) BMP Summary Tables contained in this document. The Program also includes
specific Measures of Success that are described in Section 11 of this document. The goal of
Program Administration is to implement, manage and oversee the provisions of the Storm Water
Plan to control to the maximum extent practical the discharge of pollutants from the municipal
storm sewer system associated with stormwater runoff and illicit discharges, including spills and
illegal dumping and to ensure that all Phase II Permit requirements are effectively and efficiently
fulfilled.

Section 6: Illicit Discharge Detection and Elimination Program
6.1 Program Overview
CMSWS has developed, implemented, and enforced an Illicit Discharge Detection and
Elimination(IDDE) Program in Mecklenburg County's Phase II jurisdictions/entities. The
Program includes 10 separate BMPs and 54 Measurable Goals as described in Table 4 below.
The Program also includes specific Measures of Success that are described in Section 11 of this
document. Program activities are administered by an Environmental Supervisor working in
cooperation with an Environmental Manager and multiple key staff with CMSWS's Water
Quality Program. The goal of the IDDE Program is to detect and eliminate illicit discharges into
the MS4, which are defined in 40 CFR 123.26(b)(2) as discharges that are not composed entirely
of storm water except discharges pursuant to a NPDES Permit(other than the NPDES Permit for
discharges from the municipal separate storm sewer) and discharges resulting from fire-fighting
activities as well as incidental non-storm water discharges or flows that are not significant
contributors of pollutants.
6.2 Status of the Implementation of the Storm Water Plan in FY2023
Table 4 describes in Column A the BMPs identified in the Storm Water Plan for Stormwater
Management Program Administration. The specific actions (i.e., Measurable Goals) undertaken
for implementation of these BMPs are described in Column B with the schedule provided in
Column C. Column D includes the Annual Report Metrics, indicating whether the Measurable
Goals were completed and whether compliance with the Storm Water Plan and Permit was
achieved. Column E includes the Activity Report number from our Cityworks database that
includes detailed documentation of completion of the BMPs and Measurable Goals as well as the
Attachment#that contains data and information generated from the completion of the
Measurable Goals.

Section 7: Construction Site Storm Water Runoff Control Program
7.1 Program Overview
Construction Site Runoff Control Programs have been developed and are currently being
implemented for addressing the discharge of sediment and other pollutants from construction
sites in Mecklenburg County 's Phase II jurisdictions that disturb one or more acres of land
surface and those activities less than one acre that are part of a larger common plan of
development as authorized under the Sediment Pollution Control Act of 1973. These are
delegated programs under NCGS 113A-60. The Program includes 3 separate BMPs and 12
Measurable Goals as described in Table 5 below. The Program also includes specific Measures
of Success that are described in Section 11 of this document. Program activities are administered
by an Environmental Supervisor working in cooperation with an Environmental Manager and
multiple key staff with CMSWS's Permitting and Compliance Program. In November 2019, the
Town of Huntersville received delegated authority from the State to administer a local erosion
control program in their jurisdiction. The Town of Huntersville coordinates with the County in
the completion of the activities associated with the Construction Site Erosion Control Program
described in this Section. Kevin Fox, Public Works Director, serves as the responsible party for
compliance with the Permit requirements for the Construction Site Storm Water Runoff Control
Program in the Town of Huntersville. His contact information is as follows: 704-766-2320 and
[e-mail].

Section 1: TMDLs in Mecklenburg County
The purpose of this document is to satisfy the Total Maximum Daily Load (TMDL)reporting
and assessment requirements for the period July 1, 2022 through June 30, 2023 (FY2023) as
specified in Section H of NPDES Phase II Storm Water Permit Number NCS000395.
Several of the TMDL watersheds in Mecklenburg County span both Phase I and Phase II
jurisdictions. All Phase I and Phase II TMDL compliance efforts are administered by Charlotte-
Mecklenburg Storm Water Services (CMSWS), which includes both City of Charlotte (City) and
Mecklenburg County (County)programs. The City's program is responsible for compliance
with its Phase I storm water permit and Mecklenburg County's program is responsible for Phase
II permit compliance for the County, Charlotte-Mecklenburg Schools, Central Piedmont
Community College and the Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill,
and Pineville. To ensure effective coordination, the City and County have agreed that the City
will serve as the lead jurisdiction for compliance with TMDL requirements when the majority of
the TMDL watershed lies within the Phase I jurisdiction. When most of the watershed lies
within Phase II, the County will serve as the lead. The lead jurisdiction is responsible for
coordinating and implementing all required TMDL compliance efforts and submitting all the
required plans and reports to the State. They are also responsible for coordinating with the other
jurisdictions as necessary in the implementation of compliance efforts. Table 1 indicates the lead
jurisdiction for all the approved TMDLs in Charlotte-Mecklenburg.
Charlotte-Mecklenburg Storm Water Services (CMSWS) has reviewed the 2022 303(d) list and
integrated 305(b) and 303(d)reports and determined that no new TMDLs were approved in
Mecklenburg County in FY2023; therefore, no changes were made to the TMDL Water Quality
Recovery Program described in Section 11 of the November 2022 version of the Storm Water
Management Plan(SWMP) developed for compliance with NPDES NCS000395.
Section H of NPDES Permit Number NCS000395 identifies the objective of a Water Quality
Recovery Program for TMDLs as reducing levels of the pollutant of concern in accordance with
approved Waste Load Allocation (WLAs) assigned to stormwater in an approved TMDL. The
Permit includes the following requirements for TMDL watersheds in the Phase II jurisdictions of
Mecklenburg County:
1. Within 12 months of the final approval of a TMDL, the permittee's annual reports shall
include a description of existing programs, controls,partnerships,projects, and strategies
to address impaired waters and a brief explanation as to how the programs, controls,
partnerships,projects, and strategies address impaired waters.
2. Within 24 months of the final approval of a TMDL, the permittee's annual reports shall
include an assessment of whether additional structural and/or non-structural BMPs are
necessary to address impaired waters and a brief explanation as to how the programs,
controls,partnerships,projects, and strategies address impaired waters
3. Within 36 months of the final approval of a TMDL, the permittee's annual reports shall
include a description of activities expected to occur and when the activities are expected
to occur.

Section H of NPDES Permit Number NCS000395 further specifies that if subject to an approved
TMDL, the Permittee is in compliance with the TMDL if the permittee complies with the
conditions of this permit, including developing and implementing appropriate BMPs to reduce
non-point source pollutant loading to the maximum extent practicable (MEP). While improved
water quality is the expected outcome, the NPDES MS4 permit obligation is to reduce non-point
source pollutant loading to the maximum extent practicable (MEP). The MS4 Permittee is not
responsible for attaining water quality standards (WQS) at the ambient monitoring stations. The
Division expects attaining WQS will only be achieved through reduction from the MS4, along
with reductions from other nonpoint source contributors.
The purpose of the annual report and assessment contained herein is to describe how the above
permit requirements have been satisfied for the approved TMDLs applicable to Mecklenburg
County as described in Table 1. Figure 1 shows the locations of these receiving waters in
relation to the Phase I and Phase II jurisdictions in Mecklenburg County.

Section 2: Efforts to Address Impaired Waters in Mecklenburg County
The efforts undertaken to address impaired waters in Mecklenburg County, including programs,
controls,partnerships,projects, and strategies, are performed by CMSWS. As described in
Section 1, Mecklenburg County staff with CMSWS lead these efforts in the Phase II jurisdictions
and the City of Charlotte in Phase I partnering with the County. This Section discusses these
efforts in the Phase II jurisdictions only, including all data that is reported (see Appendix A). It
is important to note that Mecklenburg County is only responsible for compliance efforts in Phase
II, which includes the TMDLs for Goose Creek, Rocky River, and Lake Wylie. Mecklenburg
County's efforts are described in detail in its TMDL Water Quality Recovery Program contained
in Section 11 of the SWMP developed for compliance with NPDES NCS000395.
2.1 BMPs and Associated Measurable Goals
During FY2023, all the BMPs and measurable goals identified in the Phase II Permit
NCS000395 and the associated SWMP were effectively fulfilled as described in Table 2. The
table also provides the Activity Report number from the County's Cityworks database that
includes documentation of the work completed for each BMP. The subsections following Table
2 describe the existing programs, controls, partnerships, projects, and strategies to address
impaired waters (herein referred to as BMPs) and a brief explanation as to how these BMPs
function. These subsections also describe the specific activities completed in FY2023 through
the implementation of these BMPs. Section 3 provides an assessment of current BMP
effectiveness, including an analysis of applicable monitoring data. Section 4 provides a
description of additional BMPs implemented in FY2023, as well as those planned for
implementation in FY2024 along with an implementation timeline, and a brief explanation as to
how these additional BMPs will address impaired waters.

2.2 Description of Existing BMPs and Their Effectiveness
The pollutants of concern for the TMDL watersheds in Mecklenburg County are dissolved
oxygen, fecal coliform bacteria, turbidity, and chlorophyll-a, which is associated with elevated
nutrients (see Table 1). CMSWS has identified the existing BMPs described in the following
subsections as effective for addressing these pollutants of concern. These subsections include a
description of the specific activities completed during FY2023 through the implementation of
these BMPs in the Phase II jurisdictions. Appendix A provides all data collected through the
implementation of these activities. The data contained in Appendix A is broken out in the
following applicable subsections. For data applicable to Phase I, contact Charlotte Storm Water
Services. Details regarding BMP implementation are provided in the SWMP.
2.2.1 Public Education & Outreach (Section 3 of SWMP)
Public education and outreach activities work to improve impaired water quality by informing
the community of the impacts of the pollutants of concern on the quality and usability of water
bodies and the steps that the public can take to reduce these pollutants. During FY2023, the
following existing public education and outreach activities were implemented in Mecklenburg
County, including all the TMDL watersheds:

2.2.4 Charlotte Water Program
The City's water and sewer utility department (Charlotte Water)maintains a public education
program focused on keeping food related fats, oils, and grease from being discharged to the
sanitary sewer system in the Phase I and Phase II jurisdictions. In recent years, the focus of this
program has been expanded to include wipes and paper towels that can be flushed down the
toilet. The program is referred to as "Flow Free." This effort helps to reduce clogging and
blockages in the system and prevent S SOs,which can introduce fecal coliform and other
pollutants to water bodies. The program has proven to be effective and will continue to be
implemented in FY2024.
2.2.5 Sewer Use Ordinance
Implementation and enforcement of the Sewer Use Ordinance by Charlotte Water in the Phase I
and Phase II jurisdictions provides the legal mechanism to ensure proper use and connection to

Section 3: Current TMDL Monitoring Strategies
CMSWS conducts fixed interval stream monitoring every month at 33 locations across the
county in the Phase I and Phase II jurisdictions (see Figure 3). Many of these locations are
within, or immediately downstream of, the TMDL watersheds that are shown in Figure 1. At
each site, samples are collected and analyzed for 16 water quality parameters as follows:
ammonia-nitrogen, fecal coliform bacteria, total Kjeldahl nitrogen, nitrate/nitrite, total suspended
solids, total phosphorus, E. coli, turbidity, suspended sediment, magnesium, calcium, hardness,
and copper(dissolved). Lead(dissolved), chromium(total), and zinc (dissolved) are collected in
the first month of each quarter. CMSWS also performs annual or bi-annual monitoring for
benthic macroinvertebrates in the Phase I and Phase II jurisdictions at the 33 stream monitoring
locations shown in Figure 3.

CMSWS maintains a Continuous Monitoring and Alert Notification Network or CMANN at 34
locations, including 27 of the fixed interval monitoring locations shown in Figure 3. The
CMANN network collects data hourly for turbidity, dissolved oxygen, temperature, conductivity,
and pH. CMSWS conducts routine lake monitoring at 27 locations on Lake Norman, Mountain
Island Lake and Lake Wylie, including seven locations in the TMDL area identified in Figure 1
for Lake Wylie. This monitoring is performed every other month for the following 12

parameters: secchi depth, temperature, dissolved oxygen, conductivity,pH, fecal coliform
bacteria, ammonia nitrogen, nitrate+nitrite, total Kjeldahl nitrogen, total phosphorus, turbidity,
and Chlorophyll-a. Monitoring for the following 11 parameters is performed twice a year:
copper, chromium, lead, zinc, mercury, manganese, arsenic, cadmium, nickel, selenium, and
iron. Additionally, semi-annual monitoring is performed at 10 locations in eight coves on Lake
Wylie to monitor potential impacts associated with a long-term residential development project.
These semi-annual samples are analyzed for the same 12 parameters measured during bi-monthly
routine monitoring. All monitoring results that exceed threshold values are referred for follow-up
under the Illicit Discharge Detection and Elimination(IDDE) Program. Long-term assessment
for trends is performed on a non-fixed frequency (as needed). Provided below is an assessment
of the data collected for the identified parameters in the three (3) TMDL watersheds where
Mecklenburg County is assigned as the lead, including the Rocky River and Goose Creek
impaired for fecal coliform bacteria and Lake Wylie impaired for nutrients (see Table 1). For
data applicable to the other TMDL watersheds in the Phase I jurisdiction, contact Charlotte
Storm Water Services. The discussions in the following subsections are limited to data collected
up to the end of 2022 as the Federal TMDL Program operates on a calendar year basis as
opposed to the fiscal year basis utilized by CMSWS.
3.1 Rocky River Fecal Coliform Monitoring and Land Use Evaluation
A section of the Rocky River in Mecklenburg County (AU Number 13-17a) is subject to a fecal
coliform TMDL with a WLA assigned to storm water that was approved on September 19, 2002.
According to the final NC 2022 305(b)report, the Rocky River is currently not meeting the fecal
coliform criteria. Mecklenburg County has been assigned responsibility for this TMDL on
behalf of the Phase I and Phase II jurisdictions in Charlotte-Mecklenburg. Phase II Permit
conditions required that a monitoring plan be developed for the Fecal Coliform TMDL in the
Rocky River Watershed unless a waiver is obtained from NCDEQ. Such a waiver was obtained
on June 26, 2014, based on the condition that Mecklenburg County continue to evaluate the land
use and development within the watershed on an annual basis and if additional storm water
infrastructure is installed or higher intensity land uses are constructed a Monitoring Plan would
be reconsidered. In response to this condition, CMSWS has obtained impervious area and land
use data from the County GIS Department back to 2011 and continues to update this data
annually(see Table 19). Between 2021 and 2022, the residential impervious cover increased
0.06 acres to a total of 16.09 acres. However, the commercial impervious cover remained
unchanged at 0.33 acres during the same time. The total amount of impervious cover in the
watershed(residential+ commercial) is approximately 16.42 acres as of 2022. Compared to the
total area of the watershed at 747 acres, the amount of impervious cover is at 2.2%,which is an
increase of 0.25% since 2011. The number of outfalls is unchanged from 2020 at four(4), which
has increased by three (3) outfalls since 2011. To date, changes in the watershed are not
significant enough to warrant the establishment of a Monitoring Plan.

Although CMSWS does not perform monitoring in the Rocky River TMDL watershed, it obtains
monthly monitoring data collected by the NCDEQ, Division of Water Quality at Q7330000,
which is the specific monitoring location for this TMDL. CMSWS performed an analysis of the
fecal coliform data collected by the State in calendar year 2022, which is the most current data
available. The geometric mean concentration of fecal coliform samples collected in 2022 was
602.704 CFU/100 ml. This represents an approximately 23% increase from the geometric mean
concentration(491 CFU/100 ml) observed in calendar year 2021. Out of the 11 samples
collected in 2022, seven (27%) exhibited concentrations below 400 CFU/100 ml. The remaining
five samples (73%) exceeded the 400 CFU/100 ml threshold. The North Carolina
Administrative Code (NCAC) 02B Fresh Surface Water Quality Standards dictate that fecal
coliform"shall not exceed a geometric mean of 200 (CFU)/100 ml...nor exceed 400 [CFU]/100
ml in more than 20 percent of the samples examined...". The data from site Q7330000 suggest
an increase in mean fecal coliform concentration over the past four(4)years; however, mean
fecal coliform concentrations and compliance percentages have improved overall since the 1970s
(Table 20, Figure 4, and Figure 5).

3.2 Goose Creek Fecal Coliform Monitoring
As identified in Table 1, two (2) sections of Goose Creek in Mecklenburg County(AU Numbers
13-17-18a and 13-17-18b) are subject to a fecal coliform TMDL with a WLA assigned to storm
water that was approved on July 8, 2005. According to the NC final 2022 305(b) report, fecal
coliform concentrations in Goose Creek are currently not meeting state water quality standards.
Mecklenburg County has been assigned responsibility for compliance with this TMDL on behalf
of the Phase I and Phase II jurisdictions in Charlotte-Mecklenburg. CMSWS maintains a fixed
interval monitoring site (MY9) located where Stevens Mill Road crosses Goose Creek in Union
County. In calendar year 2022, fecal coliform counts at this station ranged from 207 Colony-
Forming Units per 100 milliliters of water(CFU/100 ml) to 2,380 CFU/100 ml with a geometric
mean of 372.08 CFU/ 100 ml. Eleven(11) of the 17 samples collected in 2022 (64.71%)
exhibited concentrations at or below 400 CFU/100 ml. The remaining 6 samples (35.29%)
exhibited concentrations above this threshold. No pollution sources were identified as a result of
the water quality monitoring in the Goose Creek TMDL watershed in 2022. Table 21 provides a
summary of this data from 2017 through 2022. Figures 6 and 7 provide a comparison of fecal
coliform data indicating overall improvements in mean fecal coliform concentrations and

3.3 Lake Wylie Chlorophyll-A Monitoring
Two (2) sections of Lake Wylie in Mecklenburg County(AU Numbers 11-(122) and 11-
(123.5)a) were previously subject to a nutrient(nitrogen and phosphorus) TMDL that was
approved on February 5, 1996. However, according to the 2022 Integrated Report these sections
are included in Category 1 indicating they are meeting the Criteria without any
acknowledgement of a TMDL, which would be Category lt. All 82 Chlorophyll-a samples
collected by CMSWS in Lake Wylie in 2021 were below the standard of 40 µg/1 as illustrated in
Figures 8 and 9 below.

3.4 Mercury Monitoring Statewide
As stated in sub-section 9.5.3 of the Storm Water Plan, the State did not include an MS4 NPDES
WLA for mercury in their statewide TMDL. Therefore, this document does not discuss
compliance measures or data analysis for this TMDL.
3.5 Effectiveness of BMPs Based on Data Analysis
The mean fecal coliform concentration observed in Rocky River in 2022 increased from 2021;
however, mean fecal coliform concentrations and compliance percentages have remained
relatively consistent over the past five (5)years. In Goose Creek, the mean fecal coliform
concentration exhibited a moderate increase between 2021 and 2022. The percentage of samples
complying with applicable fecal coliform standards decreased slightly over the same time.
However, fecal coliform concentrations and compliance percentages have exhibited overall
improvements since the mid-2000s when Mecklenburg County initiated its TMDL compliance
efforts. The existing BMPs for both the Rocky River and Goose Creek watersheds appear to be
effective at identifying and eliminating pollution sources in compliance with TMDL
requirements. Therefore, these BMPs, along with the additional BMPs identified below, will
continue to be implemented in FY2024.
Based on the above-described assessments of data collected in the TMDL watersheds, a general
improvement in Chlorophyll-a has been observed in Lake Wylie over the past several decades.
In 2022, none of the Chlorophyll-a samples collected from Lake Wylie by CMSWS exceeded the
state standard of 40 µg/L. Therefore, it is determined that no additional BMP measures will be
implemented in the Lake Wylie TMDL watershed other than those currently implemented
countywide as part of the SWMP.
Section 4: Additional BMP Measures
As required by Permit No. NCS000395, CMSWS is continuing to evaluate the effectiveness of
the existing structural and/or non-structural BMPs described in the previous sections and identify
and implement additional BMPs as necessary to effectively address impaired waters. The
following subsections describe the additional BMPs implemented in FY2023, as well as those
planned for implementation in FY2024 along with an implementation timeline, and a brief
explanation as to how these additional BMPs will address impaired waters.
4.1 Additional BMPs Implemented in FY2023
During FY2023, the following additional activities were completed to reduce fecal coliform
bacteria levels and enhance water quality in the Rocky River watershed:
1. NCDEQ, Division of Water Quality continued to conduct water quality monitoring,
including sampling for fecal coliform bacteria, at site Q7330000 on the Rocky River.
Monitoring results will be analyzed and described in the FY2024 annual report.
2. During FY2023, two (2)notices of violation were issued by the Mecklenburg County
Health Department for septic system failures in the Goose Creek Watershed and one (1)

3. On August 10, 2022, the four(4)major outfalls in the Rocky River TMDL watershed in
Mecklenburg County were inspected. No dry weather flows or pollution sources were
detected.
4. During FY2023,there were three (3) sewer pump stations in operation in the Goose
Creek and none in the Rocky River TMDL watersheds. The Goose Creek pump stations

were inspected as follows: Philadelphia Presbyterian Church Lift Station(Activity Report
#75990), Mint Lake Village Lift Station(Activity Report#75991), and Bain Elementary
School Lift Station (Activity Report#76125). All pumps at the lift stations were present
and operable, the wet wells were free of excessive debris, and all floats/controls for
pumps were operable along with their corresponding audio and visual alarms. In
addition, the facilities were properly secured with a 24-hour notification signage posted.
However, the telemetry systems that provide automated notification when a pump failure
occurs were not operable during the inspection. Following the inspections,
recommendations were made to the owners of these systems to correct the problems with
these telemetry systems. Follow-up inspections conducted by CMSWS in July 2023
revealed that all the telemetry systems were repaired and were fully operational. Isiah
Glover with Charlotte-Mecklenburg Schools confirmed that the Bain Elementary School
lift station telemetry is now connected to a 24hr local police dispatch which will alert the
appropriate CMS service contractors that there is an issue at the lift station. This was
previously connected to a CMS office which was not a 24 hour line. The Mint Lake
Village and Philadelphia Presbyterian Church lift stations are now serviced by McCall
Brothers and confirmed the telemetry systems are now connected directly to McCall
Brothers 24hr phone line. These lift stations were previously serviced by Aqua-Trol but
they are no longer in business.
5. Routine fixed interval monitoring was conducted monthly at site MY9 (Goose Creek—
Stevens Mill Road) for 16 parameters including fecal coliform and E. coli. Monitoring
results are described in Section 3.2.
4.3 Additional BMPs to be Implemented in FY2024
During FY2024, the following additional BMPs will be implemented in the Rocky River and
Goose Creek watersheds to reduce fecal coliform bacteria levels and enhance water quality:
1. By June 30, 2024, CMSWS will complete a review of Health Department records to
determine where failed septic systems have been identified in both the Rocky River and
Goose Creek TMDL watersheds. Follow up inspections and monitoring will be
performed as necessary to ensure the elimination of sources of fecal coliform bacteria
associated with failed septic systems thereby addressing impaired waters.
2. By June 30, 2024, major outfalls will be inspected in the Rocky River TMDL watershed.
Dry weather flows will be identified, and pollution sources eliminated thereby addressing
impaired waters.
3. In April 2024, the three (3) sewer pump stations located in the Goose Creek watershed
will be inspected and the necessary corrective actions implemented to ensure proper
operation and maintenance. Currently, there are no sewer pump stations in operation in
the Rocky River TMDL watershed. If any are added in FY2024, they will be inspected
as well.
4. Routine monitoring will continue to be performed monthly by CMSWS at MY9 on
Goose Creek at Stevens Mill Road and by NCDEQ, Division of Water Quality at site
Q7330000 on Rocky River at SR 2420. Exceedances of established water quality watch
and action levels will be identified and follow up actions conducted as necessary for the
identification and elimination of pollution sources.

5. Targeted surface water sampling in headwater areas of the Goose Creek watershed will
continue in FY2024. Based on the results of FY2024 activities, additional surface water
quality and watershed data is needed to further delineate sources of fecal coliform to the
system. Watershed modeling and septic system assessments will be utilized to inform
decision making and identify potential problem areas.
Section 5: Tracking and Reporting Success
CMSWS will document all activities completed for the identification and elimination of
pollution sources in the TMDL watersheds, including all inspections conducted and corrective
actions implemented. All confirmed pollution sources will be mapped in GIS and, where
possible,pollutant loads will be estimated. This data will be tracked over time as a measure of
the success of program activities.
Section 6: TMDL Reporting
This report fulfills the SWMP TMDL reporting requirement by providing a summary of the
following:
1. Description of water quality restoration activities completed during the past fiscal year.
2. Description of water quality restoration activities expected to occur next fiscal year.
