Section 1: Introduction
This document satisfies the annual 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.
The purpose of the Storm Water Plan is to describe the actions undertaken by the Permittee to
ensure compliance with Permit requirements, including all BMPs and their associated
measurable goals. Implementation of the BMPs consistent with the provisions of the Storm
Water Plan constitutes compliance with the standard of reducing pollutants to the maximum
extent practicable as required by the Permit. 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).
Section 2 of this annual report provides background information regarding the implementation of
the Storm Water Plan, including a fiscal analysis. Sections 3 through 9 of this document provide
the following:
• Detailed description of the status of the implementation of the Storm Water Plan,
including information on the development and implementation of each major component
of the plan between July 1, 2018 and June 30, 2019 (FY2019). Activities and associated
schedules for implementation of the Storm Water Plan during FY2019 are contained in
the Permittee’s FY2019 Work Plan, which is available upon request.
• Description of any proposed changes to the Storm Water Plan, including a justification
for these changes and how the changes will impact the effectiveness of the Storm Water
Plan.
• Summary of data accumulated through the implementation of the Storm Water Plan,
including an evaluation of this data.
• Assessment of compliance with the Permit requirements, including a description of the
specific BMPs implemented and whether the measurable goals for these BMPs have been
satisfied. Additional detail regarding these BMPs and measurable goals is provided in
Sections 3 through 9 of the Storm Water Plan provided at the above website.
Section 10 of this document provides an evaluation of overall program compliance and the
effectiveness of the Storm Water Plan as well as the individual BMPs contained in the Plan.
Section 11 describes the program modifications to be implemented effective July 1, 2019 to
accomplish the intent of the Storm Water Plan and enhance overall Program effectiveness.
Section 12 describes the modifications to the Storm Water Plan for FY2020 as a result of the FY
2019 evaluation of the effectiveness of the Plan.

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. 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. Funding for
implementation of the Storm Water Plan is shared by each jurisdiction based on an adopted
Funding Strategy. The Phase II budget for FY2020 is $630,748.80 with $531,980.88 (84%) for
staff costs and $98,767.92 (16%) for operating costs. Table 1 provides a breakdown of the
FY2020 budget by jurisdiction/entity. Table 2 provides a cost breakdown by program task. The
Phase II jurisdictions utilize the revenue they receive from their storm water fee to fund the
implementation of the Program with the exception of CMS and CPPC, which do not receive
revenue from the storm water fee and therefore fund Phase II Program implementation through
their general budget. Additional funding information is available upon request, including the
documentation for the FY2020 Funding Strategy.

The targeted pollutants, sources and audiences for FY2019 are described in Table 3
of the Storm Water Plan. One of the public education methods used in FY2019 was
the distribution of educational materials by staff at events and public meetings as
well as when conducting inspections and responding to citizen requests for service.
Handouts are also available to the public on the CMSWS website under the
“Surface Water Quality” tab by selecting “Pollution Prevention.” The following
handouts/brochures/pamphlets have been developed:
• A Guide to Used Oil Recycling

During FY2019, educational newsletters were developed and disseminated to the
Phase II co-permittees covering the targeted pollutants described above. These
newsletters focused on the actions the public should take to reduce pollution,
including participating in volunteer programs, and reporting suspected pollution
problems. The @StormWaterCM social media accounts (Facebook, Twitter &
Instagram) were used as the main method to help disseminate messages to the
Towns. Phase II social media contacts were responsible for sharing messages on
the Towns’ or institutions’ social media accounts. Due to not using social media,
Barbara Monticello with the Town of Pineville was emailed messages to be
included in the local town mailer. In order to address compliance with the Goose
Creek TMDL, additional social media messages were created for the Town of Mint
Hill that focused on reducing bacteria levels in surface waters. Social media
messages were also used to promote the sale of tree seedlings and rain barrels by
the Mecklenburg County Soil and Water Conservation District. During FY2019,
age specific educational information was developed and distributed in schools . In
October 2019, science teachers were emailed information on the water quality
educational programs being offered. As a result, 21 school presentations were
given in the Phase II jurisdiction to 516 students as follows:
• 9/28/18: Catawba Stem Festival, 5th grade, 3 classes, 94 students, Flood Plain
Model
• 3/8/19: Phoenix Montessori Academy, K-8th, 3 classes, 62 students, Journey of
a Raindrop & Enviroscape
• 4/12/2019: North Mecklenburg High School, 9 grade, 15 classes, 360 students,
Presentation and Video on Careers
In addition to school presentations, CMSWS conducted the public presentations
described in Table 4 and attended the events described in Table 5. During FY2019,
a special outreach campaign focusing on reducing bacteria level in our stream s was
again utilized. The campaign was called “Scoop the Poop.” The campaign
included Social Media Posts and videos, a website banner and additional website
information including a story map, vehicle magnets, and a flagging campaign
where at select locations piles of animal waste not picked up by owners were
“flagged” with a sign that identified harmful bacteria and parasites that could be
present in the waste. During FY2019, informational pages covering a wide variety
of topics were maintained on the Storm Water Services websi te, including current
water quality conditions, storm water pollutants and ways to minimize them,
reporting pollution, volunteering, municipal storm water projects/activities, etc.
These web pages also provide a means to register for various volunteer init iatives.
The targeted pollutants on the pollution prevention pages include: bacteria and pet
waste, turbidity, sediment, phosphorus, nitrogen, organics, fertilizers, pesticides,

yard waste, surfactants, hydrocarbons, pH, and toxic compounds. The targeted
audiences include residential, commercial and institutional. The general messages
promoted on the web pages are street to stream, only rain should go down the storm
drain, and be a Water Watcher/Volunteer. The web pages also provide contacts for
reporting pollution problems/concerns and submitting questions to staff. During
FY2019, Google Analytics showed CMSWS’s web pages had 376,617 page views,
which is an increase of 36.66% from the 275,595 page views in FY2018. This
increase is attributed to the increase in social posts and all collateral including the
website, and with direct links where possible. The pages most often visited were
the Floodplains and Maps, the Homepage, and The Big Spring Clean page. For
Industrial/ Commercial Education, staff attended and presented at the Regional
Stormwater Partnership of the Carolinas meeting on Storm Water Pollution
Prevention (SWPP) service requests. Car maintenance BMP posters were
distributed during routine inspections and service requests and also at several auto
body shops throughout the county.
Media
Campaign
PE-I(13)
During FY2019, a media campaign was developed and implemented to reach
residential, commercial, and institutional audiences with information regar ding
reporting pollution, volunteering, and flood safety. The campaign included
television, radio, online, print, and Out-of-Home ads as well as social media
(Facebook, Twitter, Instagram and YouTube). Out-of-Home ads included the 4th
Street Garage banner promoting the annual Big Spring Clean and a banner
promoting Flood Safety. Print ads included 5 Utility Bill Inserts (UBIs). UBIs are
two-sided and cover storm water related topics such as flooding, living in
floodplains, storm water pollution indicators, preventing and reporting storm water
pollution, volunteering, etc. During FY2019, UBI messages were mailed to
255,000 customers in Charlotte-Mecklenburg once a month for 5 months for a total
of 1,275,000 contacts. A summary of media outreach for FY19 is provided below.
• Number of television advertising spots developed = 2 (Telemundo & TBSC)

creeks and lakes. For FY2019, 83% of survey respondents indicated
awareness, which is an increase of 14% from the 69% in FY2018 69%. The
FY2019 survey was completed in September 2019.
• Increasing Extent of Exposure – The indicator of success is an increase in the
extent of exposure from the previous fiscal year. In FY2019, CMSWS had a
total estimated extent of exposure (also referred to as impressions) of
6,063,651, compared to 6,261,262 in FY18. While this number decreased by
3.1%, that is a very small drop in total reach when you take into account that
there was very little media for several months during FY2019 caused by the
delay created by the development of a new media strategy.
Other metrics used to measure program success showed significant increases
compared to FY2018 as follows: number of public events attended at 26 in FY2018
and 34 in FY2019 for an increase of 31% and number of presentations conducted at
12 in FY2018 and 19 in FY2019 for an increase of 58%. The FY2019 program
evaluation revealed that focusing public education and outreach efforts on the
targeted pollutants, sources, audiences, and issues described in Table 3 of the Storm
Water Plan has enabled program goals to be achieved effectively and efficiently.
Moving forward into FY2020 the media campaign will continue to focus on the
digital platforms to reach specific demographics within the targeted audience more
effectively. In addition, the second year of the Scoop the Poop Campaign first
conducted in FY2018 was again highly effective at educating and involving citizens
in activities to protect and restore water quality and will be continued in FY2020
with modifications to involve Home Owners Associations. As part of the overall
program evaluation, recommendations for improvement have been made as
described in Section 3.3 below. These recommendations will be implemented in
FY2020 through the execution of the annual Work Plan.

In FY2018, the number of volunteers with CMSWS grew to such a large number, it
was no longer feasible to hold a specific appreciation event without excluding a
large number of volunteers due to budget constraints. In FY2019, CMSWS
developed a “Thank You” campaign that recognized an overall “Volunteer of the
Year” along with recognizing a volunteer from each of our volunteer programs. As
a part of the campaign, car magnets were designed and distributed at events. The
magnets promote clean water, while also help to increase awareness of our
programs. T-shirts were designed for the volunteers of the year with the same
advertising strategy in mind. Each volunteer of the year group was the focus of a
newsletter that went out to all volunteers. Newsletter recipients were posted on all
social media channels.

program goals and that they meet or exceed permit requirements. Provided below
is a report of the status of the program’s attainment of the specific measures of
success contained in the Storm Water Plan.
• Documentation of Storm Water Program Activities – All the measurable goals
assigned to the BMPs have been satisfactorily fulfilled and properly
documented in CMSWS’s Cityworks and/or the Volunteer Database.
• Increasing Number of Volunteers – The indicator of success is an increase in
the number of volunteers compared to the previous fiscal year. In FY2019,
countywide the number of volunteers was 4,622, which represents a 3.5%
increase from 4,464 in FY2018. In the Phase II jurisdictions alone, the number
of volunteers participating in Adopt-A-Stream, Storm Drain Marking and the
Big Spring Clean totaled 1,134 in FY2019, which is an increase of 14%
compared to the 995 volunteers in FY2018.

Section 5: Illicit Discharge Detection and Elimination Program
CMSWS has developed, implemented and enforced an Illicit Discharge Detection and
Elimination (IDDE) Program in Mecklenburg County’s Phase II jurisdictions/entities. The goal
of the IDDE Program is to detect and eliminate illicit discharges into the MS4, which are defined
in 40 CFR 122.26(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.

During FY2019, Fixed Interval Monitoring was conducted on the 2nd Tuesday of
every month at 10 sites throughout the Phase II jurisdictions (see Figure 1,
MC2A1, MC3E are not FIM sites). At each site, samples were collected and
analyzed for 17 water quality parameters as follows: ammonia-nitrogen, fecal
coliform bacteria, total kjeldahl nitrogen, nitrate/nitrite, total suspended solids,
total phosphorus, enterococcus, e. coli, turbidity, suspended sediment,
magnesium, calcium, hardness, and copper (dissolved). Lead (dissolved),
chromium (total), and zinc (dissolved) were collected in the first month of each
quarter. Thirty-one (31) baseflow action level exceedances were detected during
the year. The exceedances at MC40C were associated with active greenway
construction immediately downstream. Exceedances of total phosphorus at MY14
and MY9 were associated with package wastewater treatment plant discharges in
the watershed. Table 10 identifies the Baseflow Action and Watch level
exceedances identified through Fixed Interval Monitoring performed in the Phase
II jurisdictions during FY2019.

Benthic/Habitat
Monitoring
Program
(ID-4.3)
During FY2019, benthic macroinvertebrate bioassessments were conducted at 12
sites in 10 streams within the Phase II jurisdictions, including McDowell Creek
(MC2, MC2A1, MC4; Huntersville), Torrence Creek (MC3E; Huntersville),
Clarke’s Creek (MY10; Huntersville), Gar Creek (MC50; Huntersville), West
Branch Rocky River (MY1B; Davidson), Irvins Creek (MC36; Matthews),
Fourmile Creek (MC40C; Matthews), Duck Creek (MY14; Mint Hill), Clear
Creek (MY8; Mint Hill), and Goose Creek (MY9; Mint Hill). The Mecklenburg
County Water Quality Program Stream Bioassessment Standard Operating
Procedures that were used are based on benthic macroinvertebrate sampling
methods developed by the NCDEQ Biological Assessment Branch. Taxa richness
for the pollution intolerant groups, Ephemeroptera, Plecoptera and Trichoptera,
and the North Carolina Biotic Index were calculated and used to assign a State
biological classification to each site. Eight (8) of the 12 sites were given a Stream
Bioclassification of FAIR, including: McDowell Creek (MC2, MC2A1, MC4;
Huntersville), Torrence Creek (MC3E; Huntersville), Clarke’s Creek (MY10;
Huntersville), Gar Creek (MC50; Huntersville), Irvins Creek (MC36; Matthews),
Fourmile Creek (MC40C; Matthews), and Duck Creek (MY14; Mint Hill. Four
(4) streams were rated GOOD-FAIR, including Gar Creek (MC50; Huntersville),
West Branch Rocky River (MY1B; Davidson), Clear Creek (MY8; Mint Hill),
and Goose Creek (MY9; Mint Hill). Stream habitat assessments were also
conducted at each of the 12 sites using the Enhanced version of the Mecklenburg
Habitat Assessment Protocol (EMHAP). Scores ranged from 67.4 (Impaired) to
153.4. McDowell Creek above Gilead Road received a EMHAP score of 153.4
which reflects the improvements to the stream channel stability and in-stream
habitat quality due to the recent stream restoration work. There appears to be a
water quality issue in Duck Creek as the in-stream habitat was highly rated but the
rating for the benthic community was low, indicating that h abitat was not a
limiting factor. There is an ongoing problem with the Ashe Plantation Waste
Water Treatment Plant upstream of the monitoring location that negatively
impacted the water quality in Duck Creek. Data indicated that the rural and
suburban streams are recovering from the droughts that Mecklenburg County
experienced in 2002, 2007 and 2008.

(ID-4.4)
During FY2019, fish community assessments were conducted at three (3) sites in

MC4; Huntersville), and Gar Creek (MC50; Huntersville). In fiscal year 2019, all
three (3) sites where within the Town of Huntersville (MC2, MC4, and MC50).
CMSWS follows the NCDEQ Fish Community Assessment methods which
includes electrofishing wadable streams for a 200m stretch; collecting,
identifying, measuring, and counting all fish collected. Data was then entered into
a database that calculates the North Carolina Index of Biotic Integrity (NCIBI)
score for each record. These methods are utilized so data from Mecklenburg
County can consistently be compared to other locations throughout North
Carolina. Of the three (3) Phase II sites that were sampled this year, McDowell
Creek at Beatties Ford Road (MC4) scored the highest with a Good-Fair Rating
(42). Historically, MC4 has been rated as Poor or Fair. The FY2019 rating is the
highest rating since 2005 when MC4 scored a 42 as well and this indicates that the
stream can support a healthy fish community. MC2 located upstream of MC4 in
the McDowell Creek watershed received a NCIBI score of 32 and was rated Poor.
This Poor rating suggests that this sampling location does not support a healthy
fish community. This rating is consistent with the last four (4) sampling events
dating back to 2009. The third site on Gar Creek (MC50) received a NCIBI score
of 36 and was rated Fair. This Fair rating suggests that this sampling location
does not support a healthy fish community. This rating is consistent with the last
4 sampling events dating back to 2009.

Water Quality
Monitoring
Data QA/QC
(ID-4.6)
The data from the various physical, chemical, and biological monitoring activities
performed by CMSWS is maintained in a controlled Microsoft Access data
repository, with user restrictions. To ensure the highest standards of laboratory
data, duplicate samples for each site are collected each year. Field blanks, bottle
blanks, DI water blanks, and trip blanks are combined into Event Blanks for each
sampling run. Of 653 blanks collected during FY2019, one (1) exceeded the
minimum detection limit for Bromide on 7/5/18 at 0.0077 mg/L during water
intake sampling. 6726 laboratory sample records were reviewed and approved or
rejected as appropriate. Additional review of field data and biological data
occurred on an as-needed basis throughout the year.

Problem Area
Identification
and Elimination
(ID-4.7)
CMSWS uses a Stream Use Support Index referred to as SUSI to assess general
water quality conditions in the Phase II jurisdictions based on data collected.
SUSI is used as one of CMSWS’s IDDE tool. SUSI overall continues to fluctuate
between 67 and 71, on the lower side of historical records. Again, 10 out of 12
fixed interval monthly sampling events have been after storm events, leading to
elevated sediment and bacteria loads in the streams. One (1) site however, MY10,
was showing elevated total phosphorus and metals concentrations. This
watershed has been investigated before, but no definitive source has been
identified. Starting in June 2019, three (3) additional sites were added to the fixed
interval run to help bracket this watershed to determine the most likely potential
areas of contribution to these elevated concentrations.

CMANN
(ID-4.10)
In FY2019 CMSWS conducted continuous automated monitoring or CMANN
activities at 7 sites in the Phase II jurisdictions resulting in the collection of
290,022 QA/QC accepted data points (~86.1% data acceptance rate). All data
collected was evaluated for the identification of potential pollution problems and
general water quality trends. Current data can be observed on the following
website: http://cmann.mecknc.gov. CMANN data is used to calculate the Stream
Use Support Index (SUSI), which is a general indicator of water quality
conditions in our streams. This index was made available to the public on the
website as follows: http://stormwater.charmeck.org (select “Water Quality” at the
top of the page). The Phase II CMANN sites include MC4 – McDowell Creek

observe or detect any pollution problems in the Phase 2 jurisdictions.
Beginning in 2016, CMSWS began integrating new hardware into all monitoring
sites throughout Mecklenburg County. As of July 24, 2019, four (4) of the seven
(7) Phase II sites have been converted to the new EXO technology. All sites will
be converted by FY2021. In FY2020, CMANN staff will remain diligent in
maintaining the equipment to ensure that we retain the highest quality data
possible.

Public Outreach
Program for
Illicit
Discharges &
Improper Waste
Disposal
(ID-5)
During FY2019, CMSWS implemented a public outreach program to infor m
public employees, businesses, industries and the general public of the hazards
associated with illicit discharges and improper disposal of wastes. This outreach
campaign includes instructions for properly reporting these problems to CMSWS.
During FY2019, television and radio ads, as well as social media, handouts and
brochures were the primary outreach mechanisms. Handouts and brochures have
been developed and are typically distributed during the performance of facility
inspections, when responding to citizen request for service, and at event displays.
Problem businesses and industries that have a history of illicit discharges are
informed of the threat to the environment from these discharges as well as the
requirements of the Storm Water Pollution Contr ol Ordinance(s) through the use
of “Environmental Notices.” These notices are distributed by staff when
responding to citizen requests for service, conducti ng facility inspections and
performing other field activities. PE-10 and PE-I(13) on pages 5 and 7 describe
additional outreach efforts completed in FY2019. Beginning in FY2015,
municipal employees who have the potential to observe a water quality problem
were providing training using a video entitled “Water Pollution: What to do?”.
The video teaches what water pollutants look like, and provides the proper
contacts to report pollution problems. By September 30, 2015, field staff in the
following Mecklenburg County programs completed this training: Air Quality,
Code Enforcement, Solid Waste, Environmental Health, Social Services, Parks
and Recreation, and the Sheriff’s Office. The following employees at the Towns,
CPCC and CMS also completed this training: maintenance workers, firefighters,
policemen, public works and utility workers, and parks and recreation. According
to the Storm Water Plan, all municipal employees who have the potential to
observe a water quality problem will receive training at a minim um of once during
the five (5) year permit term. The above described training fulfills this
requirement for the permit term ending November 10, 2016. The second round of
training will be completed prior to end of the next permit term on February 16,
2022.

During FY2019, streams were walked in the Phase II jurisdictions in conjunction
with the Phase I stream walks in the City of Charlotte. Policies and procedures for
the stream walk program were reviewed and updated as necessary. Staff training
was performed on 10/23/2018. Stream walks began on 11/1/2018 and were
concluded on May 16, 2019. During FY2019, staff walked approximately 58.62
stream miles in the Phase II (51.78) and ETJ jurisdictions (6.84). The following
miles were assessed within each municipal boundary (see Figure 2): 27.10 miles
in Matthews, 22.73 miles in Mint Hill, 1.86 miles in Pineville, and 0.08 miles in
Stallings. 6.84 miles were walked in the ETJ areas of the Towns. As a result of
stream walk activities, 157 features were mapped in Matthews, 95 in Mint Hill, 4
in Pineville, 3 in Stallings, and 25 in the ETJ areas. In all, there were 284 points
or features mapped, 63 outfalls inspected, 151 new outfalls identified, and 103
fecal coliform samples collected. Seven (7) of these samples resulted in bacteria
action level exceedances (>3000 col/100ml). No exceedances above the action
level for total phosphorus were detected (0.50 ppm). Two (2) buffer/floodplain
disturbances were identified and reported. No illicit discharge pollution sources
were observed during 2019 Phase II stream walk activities. All monitoring data
generated under this program was WQ/QCed prior to incorporated into GIS.
Overall, stream walk data was collected with consistency in the FY2019 season.

Program (IDEP)
(ID-9)
The purpose of the Illicit Discharge Elimination Program (IDEP) program is to
support and enhance Illicit Discharge Detection and Elimination (IDDE) efforts in
Mecklenburg County. The identification of pollution sources is accomplished by
investigating business corridors and industrial facilities in Mecklenburg County.
During FY2019, IDEP activities were successfully implement in the Phase II
jurisdictions. As a result, 17 storm water outfalls were inspected and one (1)
Notice of Violation was issued. In addition, seven (7) NPDES Permitted
industrial facilities were inspected. All IDEP inspection results were followed up
on and corrective actions implemented as necessary.

Inspections
(ID-U)
The purpose of the used oil facility inspections is to ensure the proper handling
and disposal of used oil and to identify and elimination pollution sources
threatening downstream water quality conditions. In FY2019, the scope of this
program was broadened to include facilities that conduct automotive repair and
maintenance, but do not accept used oil from the public. This program update was
conducted to more effectively identify and eliminate pollution sources within the
Phase II jurisdictions. In FY2019, two (2) inspections were conducted at vehicle
maintenance facilities within the Phase II jurisdictions, including:
• Action Auto & Towing, 8621 Fairview Road, Mint Hill, inspected on March
13, 2019. Inspection Result: Notice of Violation (NOV) issued for discharges
of oil to the ground from various sources. The facility conducted site
remediation and the NOV was resolved on March 20, 2019. A disposal
manifest was provided.
• Woodies Auto Service, 179 Davidson Gateway Dr, Davidson, inspected on
April 1, 2019. Inspection Result: Report was issued as “Unsatisfactory”.

Evaluate
Effectiveness of
IDDE Program
(ID-10)
During FY2019, an evaluation was completed of the effectiveness of the BMPs
for the IDDE Program as described in the latest version of the Storm Water Plan.
Section 5.3 below lists those improvements identified for implementation during
FY2020 as a result of this evaluation. Section 5.2 below describes the status of
the implementation of the improvements identified in FY2018. The FY2019
program evaluation revealed that program components and BMPs specified in the
Storm Water Plan are performing effectively and efficiently at achieving program
goals and that they meet or exceed permit requirements. Provided below is a
report of the status of the program’s attainment of the specific measures of success
contained in the Storm Water Plan.
• Documentation of Storm Water Program Activities – All the measurable goals
assigned to the BMPs have been satisfactorily fulfilled and properly
documented in CMSWS’s Cityworks and/or the Volunteer Database.
• Increasing Pollution Problems Identified – The indicator of success is an
increase in the ratio of the number of Notices of Violation issued to IDDE
inspections conducted compared to the previous fiscal year. In FY2019, the
ratio was 0.87 based on 17 NOVs issued to 196 inspections conducted. This
is the highest ratio recorded to date indicating a significant improvement in
this measure of success (see Figure 3). In addition, IDDE inspections also
identified 61 problems with 61 resolved for a ratio of 100%.
In addition to the metrics above, sections of the IDDE manual and program SOPs
were reviewed during FY2019 and updated to reflect current procedures and
practices. The IDDE program currently includes a priority basin approach in
addition to an increased fecal coliform monitoring frequency, business corridor
inspections, continuous automated monitoring, multi-family complex sewer
collection inspections, industrial facility inspections, a pet waste education
campaign, outfall inspections, and stream walks conducted in 50-acre drainage
watersheds. Quarterly “think-tank” meetings to discuss IDDE ideas where
continued in FY2019. These meetings were used to review outstanding issues,
and brainstorm future initiatives.

During FY2019, a total of 72 new projects were permitted for compliance with post-
construction ordinance requirements in Mecklenburg County’s Phase II jurisdictions
with a total of 789.7 acres disturbed. The Storm Water Administrator worked with
staff of the Permitting & Compliance Program to ensure the effective and efficient
implementation of ordinance requirements, which included making 13 formal
ordinance interpretations that were logged and recorded. The Administrator also
completed an annual review of the post-construction ordinances and the supporting
Administrative Manual and determined that no changes were necessary. During
FY2019, compliance with post-construction ordinance requirements involved
19,888 staff hours at an estimated cost of $1,702,454.82.

During FY2019, a total of 596 BMP inspections were completed in the Phase II
jurisdictions (see Table 16) involving 728 CMSWS staff hours at an estimated cost
of $54,559.01. Follow up activities were performed as necessary to ensure
compliance and all findings were successfully documented in the Cityworks
database. One (1) notices of violation was issued and no fines were assessed as a
result of these inspections. During FY2019, an inventory was maintained of projects
with structural stormwater control measures installed and implemented for
compliance with post-construction ordinance requirements at new development and
redeveloped at public and private sector sites. As of June 30, 2019, the inventory
included 800 structural stormwater control measures (see Table 17).

the program’s attainment of the specific measures of success contained in the Storm
Water Plan.
• Documentation of Storm Water Program Activities - For the FY2019 program
assessment, an evaluation of the Cityworks database has revealed that
CMSWS staff effectively documented the completion of Work Plan activities
that demonstrate achievement of each of the measurable goals for the BMPs
associated with this program.
• Improved Compliance - The indicator of success is a decrease in the ratio of
the number of noncompliant BMPs to inspections conducted compared to the
previous fiscal year. For FY2019, the ratio was 0.686 based on 409
noncompliant BMPs to 596 inspections conducted. This represents a decrease
in noncompliance from a ratio of 0.813 in FY2018; however, it represents an
increase compared to the other five (5) previous fiscal years (see Figure 5).
This indicates a slight measure of success, but additional work is needed to
continue to improve compliance. This is a recommendation for improvement
in FY2020.
In addition to the above, the FY2019 program evaluation included a review of the
post-construction ordinances for the Mecklenburg County Phase II jurisdictions.
These ordinances are supported by an Administrative Manual. In FY2019, the
ordinances and Administrative Manual were determined to be effective; therefore,
no changes were made. As part of the overall program evaluation, recommendations
for improvement have been made as described in Section 7.3 below. These
recommendation will be implemented in FY2020 through the execution of the Work
Plan.

7.3 Improvements Identified for Implementation in FY2020
The following improvements in the Post-Construction Site Runoff Control Program have been
identified for implementation in FY2020 to improve program effectiveness:
1. Increase the number of non-erosion control BMP inspectors, using additional resources to
off-set the loss of the Sr. Environmental Specialist position.
2. Increase the number of educational materials given out by incorporating accountability
measures to ensure that maintenance information is being given out to the public.
3. Continue training the Town of Huntersville staff on BMP installation inspections.
4. Develop and implement a process/plan to increase BMP compliance, including at a
minimum increased follow up inspections when noncompliance is observed.
5. Ensure that all co-permittees have Operation and Maintenance Programs for municipally-
owned or maintained structural stormwater controls installed for compliance with the
post-construction ordinances. The O&M Programs should include a written Maintenance
Plan as required by the ordinance that specifies the frequency of inspections and routine
maintenance requirements. Ensure that co-permittees are documenting inspection and
maintenance activities performed in accordance with the schedule specified in the
Maintenance Plan. Be aware that Richard Farmer with the Water Quality Program is
ensuring that the County facilities are doing the above for their structural storm water
controls.

Section 8: Pollution Prevention/Good Housekeeping for Municipal Operations
CMSWS has developed and implemented a Pollution Prevention/Good Housekeeping Program
for municipal facilities and operations. The goal of the Pollution Prevention/Good
Housekeeping Program is to reduce pollutants in storm water runoff from municipal operations.
8.1 Implementation Status for FY2019
Table 19 describes the BMPs identified in the Storm Water Plan for the Pollution Prevention/
Good Housekeeping Program and the specific actions completed between July 1, 2018 and June
30, 2019 (FY2019) for implementation of these BMPs as well as whether the measurable goals
for the BMPs specified in the plan have been fulfilled.

(PP-1)
During FY2019, a total of 660 municipal operations’ staff from the County, CMS,
CPCC, and the six (6) Towns completed the municipal training program. Table 20
below summarizes the training completed. The training focused on informing staff
of the techniques for identifying, eliminating, and reducing pollution sources at their
facilities and around the community. Pollution prevention and good housekeeping
training materials were developed using an executable program (Articulate) that
allows PowerPoint slides to be combined with pollution prevention video clips to
create one presentation module. Trainings were conducted in small group settings to
facilitate discussions on pollution issues at each facility. All trainings included the
review of Storm Water Pollution Prevention Plans (SWPPPs), Spill Response and
Clean-up Plans, and storm drainage systems. Videos produced by Excal Visual
were included in the module focusing on work typically performed at different
facility types (fleet maintenance, land disturbance, parks and recreation, solid waste,
streets and drainage, and general municipal jobs). The video identifies activities at
these facilities that can negatively impact surface water and demonstrates suggested
prevention techniques. At the end of the training, the participates reviewed the
information provided during a question and answer session.

(PP-2)
Municipal inspection procedures and inspection forms were reviewed at the
beginning of FY2019 and no significant changes were made. On July 26, 2018,
CMSWS staff received training on all Phase II municipal inspections. Training
included a review of inspection protocols, reports, and deadlines. Based on findings
from FY2018 and previous years, common problems were identified and inspector s
were instructed to provide guidance to facility managers for resolving them.
Emphasis was placed on updating Storm Water Pollution Prevention Plans
(SWPPPs) for Phase II municipal facilities and reminding facility managers to
complete their assignments over the course of the year. During FY2019, CMSWS
staff inspected 60 municipal facilities as follows; 17 for Mecklenburg County, 6 for
the Towns, 4 for Central Piedmont Community College (CPCC), and 33 for
Charlotte Mecklenburg Schools (CMS). Based on inspection findings in recent
years, several areas for improvement were emphasized during the FY2019
inspections, including proper cleanup of petroleum spills, dumpster and trash
compactor maintenance, record keeping for compliance with the Phase II stormwater
permit, and SWPPP implementation. Five (5) deficiencies were observed at County
and Town municipal facilities, which is a decrease from twelve (12) deficiencies
observed in FY2018. Three (3) deficiencies were for failure to comply with the
SWPPP. Other deficiencies included soil and mulch contamination from a diesel
fuel above ground storage tank and a diesel discharge at a fueling island. No repeat

problems were noted. All SWPPPs were reviewed and updated by CMSWS staff to
reflect any changes in the previous year and updated copies were sent to facility
managers. The four (4) CPCC campuses in Mecklenburg County inspected in
FY2019 include Central, Cato, Harper, and Merancas. Areas of emphasis for
FY2019 inspections at CPCC facilities included erosion control and SWPPP
implementation, specifically semi-annual self-inspections. Inspectors observed four
(4) deficiencies at CPCC facilities. This is a decrease from five (5) deficiencies
observed in FY2018. All four (4) campuses had failed to meet the SWPPP
requirement of performing annual non storm water discharge evaluations.
Improvement in performing the semiannual self-inspections was realized. Ten (10)
other minor issues were observed by inspectors, including accumulated sediment in
an outfall, BMP maintenance, self-inspection documentation, compromised waste
containers, minor wash water discharge, employee training records and erosion
control problems at construction projects. No follow up inspections were required
for CPCC facilities. SWPPPs were reviewed and updated by CMSWS staff and sent
to Zack Harris, Grounds and Site Coordinator for CPCC Facilities Services.
Inspections were conducted at 33 CMS facilities. Of these facilities, eight (8) have
SWPPPs and are inspected annually. CMS facilities that do not maintain SWPPPs
are inspected approximately every five (5) years. Areas of emphasis for inspections
at CMS facilities wash water discharge and other illicit discharges. Three (3)
deficiencies were observed during CMS facility inspections, a slight increase from
the two (2) deficiencies observed in FY2018. All the deficiencies were for illicit
discharges. One was due to significant oil staining and oil dry material located on
the ground adjacent to a structural canopy. The second involved spilled chemicals,
antifreeze and used oil behind a student auto shop. The third involved diesel
saturated oil-absorbent material and gravel and leaking fill ports at above ground
storage tanks. All contaminated soil was removed and properly disposed of by an
environmental cleanup contractor. SWPPP updates at CMS facilities (where
required) are completed annually by Mr. Jeff Mitchell, Environmental Health and
Safety Specialist for CMS. Inspectors did not note any problems with the SWPPPs
at CMS facilities. All observed deficiencies described above for the County, Towns,
CMS, and CPPC (excluding those associated with SWPPP requirements) were
satisfactorily corrected.

two for the Town of Huntersville. East language Academy (CMS) was added to the
FY20 inspection list. The two new locations in Huntersville were inspected and no
significant potential for stormwater pollution was observed. One CPCC facility was
inspected and no significant potential for stormwater pollution was observed. Two
facilities belonging to Mecklenburg County Parks and Recreation were observed to

Program
(PP-9)
During FY2018, an evaluation was completed of the Pollution Prevention and Good
Housekeeping Program revealing that the program components and BMPs specified
in the Storm Water Plan are performing effectively and efficiently at achieving
program goals and that they meet or exceed permit requirements. Provided below is
a report of the status of the program’s attainment of the specific measures of success
contained in the Storm Water Plan.
• Documentation of Storm Water Program Activities: For the FY2019 program
assessment, an evaluation of the Cityworks database has revealed that
CMSWS staff effectively documented the completion of Work Plan activities
that demonstrate achievement of each of the measurable goals for the BMPs
associated with this program.
• Improved Compliance: The indicator of success is a decrease in the ratio of
the number of deficiencies observed at municipal facilities to inspections
conducted compared to the previous fiscal year. In FY2019, the ratio was
0.200 based on 12 deficiencies detected to 60 inspections conducted. This
represents a decrease in noncompliance compared to FY2018 and the other
five (5) previous fiscal years except FY2017 that had the lowest ratio recorded
at 0.151 (see Figure 6). The FY2019 ratio indicates a measure of success, but
additional work is needed to continue to improve compliance. This is a
recommendation for improvement in FY2020.
An issue observed during an inspection that could negatively impact water quality or
result in a permit violation is considered a “deficiency.” During FY2019, a total of
12 deficiencies were observed. This indicates that the improvements implemented
in FY2019 helped to reduce the number of deficiencies. The reduction was also due,
in part, to the elimination of the qualitative monitoring component of the SWPPPs.
Deficiencies not related to the implementation of the SWPPP were related to issues
that might impact downstream water quality such as spills and /or leaks. These
deficiencies were resolved quickly and documented by follow up inspections.
During FY2019, a total of 123 “recommendations” for improvement, which do not
represent potential water quality problems or permit violations, resulted from facili ty
inspections in addition to the 12 deficiencies for a total of 135 findings, which are
described in Table 21 for the past 12 years. During FY2019, the majority of
findings fell into one (1) of three (3) categories, including stormwater system and
BMPs, erosion, and waste storage/disposal areas. In total, these categories
accounted for 71 findings or 52.6% of total findings. As in previous years,
overgrown vegetation, trash accumulation, and sedimentation were common
problems associated with unmaintained BMPs. Erosion was observed at various
types of facilities and was usually associated with construction activities or high-
traffic pedestrian areas. Issues at waste storage/disposal areas were observed at
several facilities and were usually associated with dumpster wear, such as broken/
missing lids and corrosion. Other relatively common issues were associated with
material storage areas (11 findings, or 8.2%), vehicle/equipment areas (11 findings,
or 8.2%), and spill response equipment (12 findings, or 8.9%). Most issues noted
were minor spills and leaks of oil and other fluids that were not properly cleaned up.
CMSWS inspectors recommended that all municipal facilities with the potential to
pollute surface waters should maintain spill kits in the appropriate areas. During
training for FY2020, emphasis will be placed on educating facility managers about
preventing common problems that were observed during FY2019. Areas of
emphasis will include erosion control (particularly at construction sites), prope r use

and disposal of absorbent materials, use and maintenance of trash dumpsters, spill
prevention during fueling operations, and maintenance of structural stormwater
BMPs. Photos of housekeeping issues and potential pollution sources observed
during inspections will be used for training presentations in FY2020. The program
evaluation also included an annual assessment of the effectiveness of the BMPs
described in the Storm Water Plan that are currently in use by Mecklenburg
County’s Phase II jurisdictions to reduce pollutants from municipally owned streets,
roads, parking lots, catch basins, and storm water convey ance systems. This
evaluation was based on FY2019 data received from the co-permittees regarding
costs and the estimated quantities of pollutants removed as described in the table
below.
BMPs Lbs. Removed Cost Cost/Lb.
Street Sweeping 921,000 $45,3250 $0.49
Parking Lot Cleaning 27,870 $15,300 $0.55
Conveyance Systems
Cleaning 84,400 $124700 $1.48
TOTALS 1,033,270 $593,250 $0.57
Based on a report produced by R.C. Sutherland in 2013 entitled Clean Streets Mean
Clean Streams, an acceptable pollutant removal range is $3 to $5 per pound. The
cost ranges reported by the co-permittees were significantly less; therefore, it is
determined that these BMPs are effective at removing pollutants and no changes are
proposed in FY2019. As part of the overall evaluation of the Pollution Prevention
and Good Housekeeping Program, recommendations for improvement have been
made as described in Section 8.3 below. These recommendations will be
implemented in FY2020 through the execution of the Work Plan.

8.3 Improvements Identified for Implementation in FY2020
The following improvements in the Pollution Prevention/Good Housekeeping Program have
been identified for implementation in FY2020 to improve program effectiveness:
1. Enhance efforts to ensure Phase II municipal operations and facilities are complying with
NPDES storm water permit requirements by emphasizing the importance of ensuring
compliance prior to the State audit in 2021.
2. Ensure that all County facilities, including Park & Recreation and Asset & Facility
Management with the County, have Operation and Maintenance Programs for
municipally-owned or maintained structural stormwater controls installed for compliance
with the post-construction ordinances. The O&M Programs should include a written
Maintenance Plan as required by the ordinance that specifies the frequency of inspections
and routine maintenance requirements. Ensure that County facilities are documenting
inspection and maintenance activities performed in accordance with the schedule
specified in the Maintenance Plan. Be aware that Corey Priddy with the Permitting &
Compliance Program is ensuring that the other co-permittees are doing the above for their
structural storm water controls.

Section 9: Total Maximum Daily Loads (TMDLs)
CMSWS has developed and implemented a program for addressing non-point source pollutant
loading associated with the Total Maximum Daily Loads (TMDLs) approved by EPA for the
receiving waters of the Phase II MS4 storm water discharges and/or waters downstream of these
discharges. The goal of the TMDL Program is to reduce levels of the pollutant(s) of concern to
the maximum extent practicable in accordance with approved Waste Load Allocation (WLAs)
assigned to storm water in the approved TMDL.
9.1 Implementation Status for FY2019
Table 23 describes the BMPs identified in the Storm Water Plan for the TMDL Program and the
specific actions completed between July 1, 2018 and June 30, 2019 (FY2019) for
implementation of these BMPs as well as whether the measurable goals for the BMPs specified
in the plan have been fulfilled.

In June 2019, the State finalized its 2018 303(d) list and integrated 305(b) and
303(d) reports. A review of these reports revealed that no new TMDLs have been
approved in Mecklenburg County. Since no new TMDLs have been approved, no
changes will be made to the existing Water Quality Recovery Programs and
Strategies. In addition, a review of the reports revealed that the legacy listings for
metals on Little Sugar (below Archdale), Sugar, Irwin, and Mallard (from source to
Stoney) were removed and the new criteria for dissolved metals was indicated as
being met. Mallard Creek was placed on Category 5 for exceeding the criteria for
Turbidity as a result of CMSWS’s data submittal. A new TMDL may be triggered
from this new listing. The City and not the County will be responsible for
compliance with this new TMDL. No new TMDLs have been developed for
Mecklenburg County since 2014. The surface waters with approved TMDLs in
Mecklenburg County flow through both Phase I and Phase II jurisdictions except
for Goose Creek and the Rocky River, which lie entirely in Phase II. To ensure
effective coordination, the City of Charlotte, which holds a Phase I Permit, and
Mecklenburg County and the Towns, which hold a joint Phase II Permit, have
agreed that the City of Charlotte 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,
Mecklenburg County will serve as the lead. Table 24 identifies the receiving
waters for MS4 discharges in Mecklenburg County that have a TMDL approved by
EPA as well as the lead organization for compliance with TMDL requirements
based on the above criteria. Figure 7 shows the locations of these receiving waters
in relation to the Phase I and Phase II jurisdictions in Mecklenburg County. The
lead jurisdiction as identified in Table 24 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.

2. By June 30, 2020, 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.
3. By June 30, 2020, 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.
4. In November 2019, design and permitting will be completed for the restoration of a 2
mile section of the Rocky River. Currently, the Rocky River is severely eroded by storm
water flows that eat away at the stream banks. The restoration project will stabilize the
stream banks to reduce erosion and improve water quality in the creek.
5. By May 2020, construction will be completed on the restoration of a 2.3 miles section of
Stevens Creek in the Goose Creek TMDL watershed. Currently, Stevens Creek is
severely eroded by storm water flows that eat away at the stream banks. The restoration
project will stabilize the stream banks to reduce erosion and improve water quality in the
creek.

Section 10: Program Assessment
During FY2019, the permittee has satisfactorily implemented the BMPs and fulfilled the
measurable goals specified in Storm Water Permit No. NCS000395 in accordance with the Storm
Water Plan as described in the previous sections. The BMPs, measurable goals and activities
described in the Storm Water Plan will continue to be implemented in FY2020 along with the
program enhancements and modifications described in Sections 11 and 12, respectively. The
other provisions of the Permit have also been satisfactorily fulfilled; therefore, compliance with
the Permit has been achieved. The permittee further finds that the implementation of the Storm
Water Plan as well as the individual BMPs contained in the Plan has resulted in satisfactory
compliance with seven (7) of the eight (8) identified measures of success as indicated in Table
25. The only measure of success not met in FY2019 was increasing the extent of exposure for
the Public Education and Outreach Program. This was due to very little media coverage for
several months during FY2019 while a new media strategy was being developed. The new
media strategy will ultimately result in significant improvements in our extent of exposure going
forward and the drop in exposure from FY2018 was only 3.1%, so the benefit far outweighs the
cost.

Section 12: Storm Water Quality Management Program Plan Modifications for FY2019
Part II, Section A of Mecklenburg County’s Phase II Permit (Permit # NCS000395) specifies
that the Storm Water Quality Management Program Plan, referred to as the Storm Water Plan,
must be kept up to date by the permittee. It further specifies that the permittee must evaluate the
effectiveness of the Storm Water Plan at least annually and modify as necessary to address any
procedural, protocol or programmatic changes. The modified Storm Water Plan must be
submitted to the Director of NCDEQ within 90 days for approval. In October 2019, CMSWS
completed its annual review of the Storm Water Plan developed for compliance with Permit #
NCS000395 resulting in the modifications described below. With these changes, the Storm
Water Plan will be effective at ensuring compliance with Permit requirements. The activities in
the Storm Water Plan
1. In the Program Goals and Objectives sections for each of the six minimum measures,
added language indicating that the goals and objects for each of the measures are based
on the actions necessary to address the targeted pollutants and pollutant sources identified
in Table 3. Also indicated that these goals and objectives would be evaluated and
updated annually.
2. Added the following to the Program Evaluation program element for each of the six (6)
minimum measures: Include the evaluation in the annual report to the co-permittees and
NCDEQ along with the activities completed during the year and the recommendations for
improvement.
3. Updated the Water Quality Program Organizational Chart in Appendix B.
4. Added a table containing co-permittee contact information as Appendix C.
5. Changed the BMP summary table (Table 2) in Section 3.2 for the Public Education and
Outreach Program to reflect the change in the numbering of the program elements in
FY2020 Work Plan.
6. Updated Media Campaign (Section 3.6.4) and Social Media (Section 3.6.5) data to reflect
2019 numbers.
7. Added Section 3.6.9 to describe CMSWS’s involvement in the Regional Storm Water
Partnership of the Carolinas.
8. In the Program Evaluation section for each of the six (6) minimum measures, added the
metrics that will be included in the annual reports to assess effectiveness at achieving
measurable goals.
9. Added the Media Campaign (PE-I(13)) to the BMP summary table (Table 4) in Section 4
for the Public Involvement and Participation Program and removed Tree Planting, which
is not done very often in the Phase II jurisdictions due to a lack of suitable sites.
10. Removed Section 4.4.6 that described tree planting events since these events will no
longer be included in the Storm Water Plan due to a lack of tree planting opportunities in
the Phase II jurisdictions. Most tree planting events occur in the Phase I jurisdiction.
11. Updated Section 4.4.6 to include new volunteer monitoring program activities.
12. Added Section 5.3 to described the written IDDE Policies and Procedures Manual.
Having these procedures is a permit requirement.
13. Added documenting and maintaining records to PC-2 in the BMP summary table (Table
7) for the Post-Construction Site Runoff Control Program as well as identifying chronic
violators for initiation of actions to reduce noncompliance. Also added to this the list of

Evaluation of Post-Construction Site Runoff Control Program
September 27, 2019
The purpose of this document is to provide a written assessment of the effectiveness of the Post-
Construction Runoff Control Program at fulfilling Phase II Permit requirements for addressing
the negative water quality impacts associated with storm water runoff from new development
and redevelopment projects in Mecklenburg County’s Phase II jurisdictions.
Effectiveness of Storm Water Quality Management Program Plan
This section includes an evaluation of the effectiveness of the BMPs for the Post-Construction
Site Runoff Control Program as described in the Storm Water Quality Management Program
Plan at complying with Phase II Permit requirements. This Plan is considered by the State as
part of Mecklenburg County’s Phase II Permit; therefore, it is essential that all components of the
Plan are implemented and effectively documented. The purpose of this evaluation is to ensure
that the Plan is effective at complying with the Permit requirements and to ensure it was fully
implemented in FY2019. Table 1 includes a description of the BMPs and Measurable Goals
included in the Plan as well as the Cityworks Activity Report numbers that describe the activities
completed for these Measurable Goals and whether the Goals were met. Following this table is
an explanation as to how these Goals were met.

PC-1 Implementation of Post-Construction Storm Water Ordinances
Effective June 30, 2007, seven (7) post-construction ordinances were adopted in Mecklenburg
County to ensure compliance with the Phase II Permit requirements, including an ordinance for
each applicable jurisdiction as follows:
1. Town of Cornelius
2. Town of Davidson
3. Town of Huntersville
4. Town of Matthews
5. Town of Mint Hill
6. Town of Pineville
7. Mecklenburg County
The ordinances adopted by the Towns are applicable to their corporate limits and extra-territorial
jurisdictions (ETJ). Mecklenburg County’s ordinance is applicable in the one (1) square mile
area south of Pineville that is outside that Town’s ETJ (see Attachment 1). Staff with Charlotte-
Mecklenburg Storm Water Services (CMSWS) administer these seven (7) ordinances for
compliance with Phase II Permit requirements. During FY2019, this involved 19,888 staff hours
at an estimated cost of $1,702,454.82 to successfully fulfill the 13 activities listed below that are
included in Section 7.3 of the Storm Water Plan to ensure compliance with ordinance
requirements. During FY2019, a total of 72 new projects were permitted in the Phase II
jurisdictions under the Post-Construction Site Runoff Control Program with a total of 789.7 acres
disturbed. There were also a total of 13 ordinance interpretations completed by the Storm Water
Administrator during FY2019. Table 2 breaks down the hours and costs by individual ordinance
compliance activities.
1. Maintaining and updating the ordinances as necessary.
2. Providing interpretations regarding the applicability of ordinance requirements to new
developments and redevelopments.
3. Maintaining and updating the Charlotte-Mecklenburg BMP Design Manual as
necessary.
4. Maintaining and updating the Administrative Manual as necessary.
5. Performing site plan reviews of all new development and redevelopment projects that
disturb greater than or equal to one acre (including sites that disturb less than one acre
that are part of a larger common plan of development or sale) and performing reviews
on new development and redevelopment that disturb less than an acre as required by
specific ordinance requirements. The site plan review addresses how the project meets
the performance standards and how the project will ensure long-term maintenance.
6. Conducting site inspections during construction to ensure compliance with approved
plans and all ordinance requirements.
3
7. Conducting a post-construction inspection before issuing a certificate of occupancy to
verify that performance standards have been met or a bond is in place to guarantee
completion.
8. Inspection findings and enforcement actions will be documented and records
maintained. Notices of violation and enforcement actions will be tracked and a
reporting mechanism established to identify chronic violators for initiation of actions to
reduce noncompliance.
9. Maintaining an inventory of public and private projects with structural storm water
control measures installed for compliance with post-construction ordinance
requirements.
10. Ensuring that mechanisms are in place, such as approved as-builts, bonds, etc., to
guarantee that projects will be maintained consistent with approved plans in
compliance with post-construction ordinance requirements.
11. Ensuring the implementation of long-term operation and maintenance plans for
structural BMPs in accordance with ordinance requirements, including ensuring that the
owner of each structural BMP has a qualified professional perform annual inspections
and maintains records of these inspections.
12. Conducting site inspections of structural storm water controls installed for compliance
with ordinance requirements at least once during the permit term. Records of
inspection findings and enforcement actions are maintained in the Cityworks database.
Notices of violation and enforcement actions are tracked and used to identify chronic
violators for initiation of actions to reduce noncompliance.
13. Implementing a program to educate the development community and the general public
concerning the post-construction storm water management requirements. Ordinances,
post-construction requirements, design standards checklist, and other materials
appropriate for developers are made available through paper or electronic means.

PC-3 Implement a Program to Educate and Assist Developers
On December 6, 2018, a training event was held to educate the community on the requirements
of the Post-Construction Runoff Control Program with approximately 120 persons attending.
The training was held jointly with the City of Charlotte and lasted approximately six (6) hours.
The training also included a history of Mecklenburg County’s water resources and information
regarding compliance with the water quality buffer requirements.

PC-5 Evaluate Effectiveness of Post-Construction Program
In September 2019, an evaluation was completed of the of the Post-Construction Site Runoff
Control Program that included an assessment of all ordinances and supporting policies,
procedures and guidelines. The successful completion by staff of the 13 compliance activities
listed on pages 2 and 3 above was a component of this evaluation. These activities are contained
in Section 7.3 of the Storm Water Plan. A review of these activities revealed that they
satisfactorily address all the requirements for compliance with the Post-Construction Site Runoff
Control Program identified in Section F of Permit No. NCS000395. Therefore, program
activities for FY2019 and the Storm Water Plan are determined to be in compliance with Permit
requirements. The Storm Water Plan contains additional information regarding measures to be
undertaken for compliance with Permit requirements all of which were successfully completed in
FY2019.
As a result of the FY2019 program assessment, one area was identified and successfully
addressed for improvement of Post-Construction Ordinance compliance efforts in the Town of
Mint Hill resulting in significant improvement in how built-upon area (BUA) is tracked and
regulated. This was accomplished on June 27, 2019 when Town zoning staff agreed to review
and verify the correctness of BUA delineations on plats and surveys prior to releasing holds on
Certificates of Occupancy. No ordinances changes resulted from this assessment and there were
no changes to the Administrative or BMP Design Manuals.
The FY2019 assessment also included an evaluation of the Measures of Success contained in the
Storm Water Plan as described below.
• Documentation of Storm Water Program Activities – As a baseline measure of success,
staff will document completion of Work Plan program activities annually that
demonstrate successful fulfillment of BMPs associated with this program element. All
activities will be documented within Cityworks.
For the FY2019 program assessment, an evaluation of the Cityworks database has
revealed that CMSWS staff effectively documented the completion of Work Plan
activities that demonstrate achievement of each of the measurable goals for the BMPs
associated with this program. The log numbers for the Activity Reports that provide
this documentation are provided in Table 1 above, with the exception of BMP
inspections, which are documented on individual Inspection Reports and not on a
single Activity Report in Cityworks.
• Improved Compliance – Structural BMPs installed for compliance with post-construction
ordinance requirements will be inspected at a minimum of once a year. CMSWS will
also periodically inspect buffers, undisturbed open space and other non-structural BMPs
to ensure their long-term effectiveness. CMSWS will track the ratio of the number of
BMPs not in compliance to BMP inspections conducted with a decrease indicating a
measure of success at improving compliance, which is a goal of the program.
For FY2019, the ratio was 0.686 based on 409 noncompliant BMPs to 596
inspections conducted. This represents a decrease in noncompliance from a ratio of
0.813 in FY2018; however, it represents an increase compared to the other five (5)
previous fiscal years (see Figure 5). This indicates a slight measure of success, but
6
additional work is needed to continue to improve compliance. This is a
recommendation for improvement in FY2020.

Section 1: TMDLs in Mecklenburg County
The purpose of this document is to satisfy the Total Maximum Daily Load (TMDL) reporting
requirement for the period July 1, 2018 through June 30, 2019 (FY2019) 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.
In June 2019, the State finalized its 2018 303(d) list and integrated 305(b) and 303(d) reports. A
review of these reports revealed that no new TMDLs have been approved in Mecklenburg
County. Since no new TMDLs have been approved, no changes will be made to the existing
Water Quality Recovery Programs and Strategies. In addition, a review of the reports revealed
that the legacy listings for metals on Little Sugar (below Archdale), Sugar, Irwin, and Mallard
(from source to Stoney) were removed and the new criteria for dissolved metals was indicated as
being met. Mallard Creek was placed on Category 5 for exceeding the criteria for Turbidity as a
result of CMSWS’s data submittal. A new TMDL may be triggered from this new listing. The
City and not the County will be responsible for compliance with this new TMDL.
No new TMDLs have been developed for Mecklenburg County since 2014; therefore, all
Mecklenburg County TMDLs have been in effect in excess of 36 months. Based on the
requirements contained in Section H of NPDES Permit Number NCS000395, the following must
be completed for compliance with the permit requirements for the TMDL watersheds:
•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
(herein referred to as BMPs) to address impaired waters and a brief explanation as to how
these BMPs function to restore water quality.
•Within 24 months of the final approval of a TMDL, the permittee’s annual reports shall
include an assessment of whether additional BMPs are necessary to address impaired
waters and a brief explanation as to how these BMPs function to restore water quality.
•Within 36 months of the final approval of a TMDL, the permittee’s annual reports shall
include a description of additional TMDL compliance activities expected to occur,
including a schedule for implementation.
2
The purpose of the annual report contained herein is to describe how the above described permit
requirements have been satisfied for the approved TMDLs applicable to Mecklenburg County’s
Phase II jurisdictions 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. Several of
the TMDL watersheds include both Phase I and Phase II jurisdictions and CMSWS performs the
activities for compliance with TMDLs countywide for all jurisdictions; therefore, where data is
available the tables below include information regarding TMDL compliance activities in both the
Phase I and Phase II jurisdictions although Mecklenburg County’s responsibility is only for
Phase II as described above.

Section 2: Assessment of Storm Water Quality Management Program Plan
This Section discusses each of the BMPs and their Measurable Goals for reducing non-point
source pollutant loading to the receiving streams of TMDL watersheds to the maximum extent
practicable as described in the Storm Water Quality Management Program Plan (SWQMPP),
including implementation status and documentation of those activities completed during
FY2019. Tables 3 through 18 describe the activities completed in FY2019 for compliance with
TMDLs. Where applicable, compliance activities are described for both the Phase I and Phase II
jurisdictions for informational purposes since several of the TMDL watersheds include both
jurisdictions; however, Mecklenburg County is only responsible for Phase II Permit compliance
for the TMDLs developed for Goose Creek, Rocky River and Lake Wylie. Tables 3 through 18
also include compliance activities performed in the McDowell Creek watershed where applicable
even though a watershed management plan and not a TMDL applies (Category 4B).
2.1 BMPs and Associated Measurable Goals
During FY2019, all the BMPs and measurable goals identified in Phase II Permit NCS000395
and the associated SWQMPP 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
address impaired waters. These subsections also describe the specific activities completed in
FY2019 through the implementation of these BMPs and whether they will be continued in
FY2020 based on an assessment of their effectiveness. Section 3 provides a further assessment
of current BMP effectiveness based on an analysis of applicable monitoring data. Section 4
provides a description of additional BMPs implemented in FY2019, as well as those planned for
implementation in FY2020 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 primary pollutants of concern for the TMDL watersheds where Mecklenburg County is the
lead, including Goose Creek, Rocky River and Lake Wylie, are fecal coliform bacteria and
chlorophyll-a (see Table 1). CMSWS has reviewed existing BMPs to address impaired waters
and has identified those described in the following subsections as suitable for best addressing the
TMDL pollutants of concern and will therefore be continued in FY2020. Details regarding BMP
implementation are provided in the SWQMPP.
2.2.1 Public Education & Outreach (Section 3 of SWQMPP)
The following existing public education and outreach activities have been identified as suitable
for addressing the pollutants of concern in the TMDL watersheds. These BMPs will address
impaired waters by informing the community of the impacts of the pollutants of concern on
water bodies and the steps that the public can take to reduce these pollutants. During FY2019,
these BMPs were effectively implemented in the Phase I and Phase II jurisdictions in
Mecklenburg County.

During FY2019, educational newsletters were developed and disseminated to the Phase I and
Phase II jurisdictions covering the targeted pollutants described above. These newsletters
focused on the actions the public should take to reduce pollution, including participating in
volunteer programs, and reporting suspected pollution problems. The @StormWaterCM social
media accounts (Facebook, Twitter & Instagram) were used as the main method to help
disseminate messages to the Towns. Phase I and Phase II social media contacts were responsible
for sharing messages on the Towns’ or institutions’ social media accounts. Due to not using
social media, Barbara Monticello with the Town of Pineville was emailed messages to be
included in the local town mailer. In order to address compliance with the Goose Creek TMDL,
additional social media messages were created for the Town of Mint Hill that focused on
reducing bacteria levels in surface waters. Social media messages were also used to promote the
sale of tree seedlings and rain barrels by the Mecklenburg County Soil and Water Conservation
District. During FY2019, age specific educational information was developed and distributed in
schools. In October 2019, science teachers were emailed information on the water quality
educational programs being offered. As a result, 21 school presentations were given in the Phase
II jurisdiction to 516 students as follows:
• 9/28/18: Catawba Stem Festival, 5th grade, 3 classes, 94 students, Flood Plain Model
• 3/8/19: Phoenix Montessori Academy, K-8th, 3 classes, 62 students, Journey of a
Raindrop & Enviroscape
• 4/12/2019: North Mecklenburg High School, 9 grade, 15 classes, 360 students,
Presentation and Video on Careers
School presentations were also performed in the Phase I jurisdiction. Table 3 describes the
school presentations conducted in the Phase I and Phase II TMDL jurisdictions in Charlotte-
Mecklenburg during FY2019.

In addition to school presentations, CMSWS conducted the public presentations and outreach
efforts described in Table 4 and attended the events described in Table 5 in both the Phase I and
Phase II jurisdictions. During FY2019, a special outreach campaign focusing on reducing
bacteria level in our streams was again utilized. The campaign was called “Scoop the Poop.”
Scoop the Poop included Social Media Posts and videos, a website banner and additional website
information including a story map, vehicle magnets, and a flagging campaign where at select
locations piles of animal waste not picked up by owners were “flagged” with a sign that
identified harmful bacteria and parasites that could be present in the waste. During FY2019,
informational pages covering a wide variety of topics were maintained on the Storm Water
Services website for Phase I and Phase II, including current water quality conditions, storm water
pollutants and ways to minimize them, reporting pollution, volunteering, municipal storm water
projects/activities, etc. These web pages also provide a means to register for various volunteer
initiatives. The targeted pollutants on the pollution prevention pages include: bacteria and pet
waste, turbidity, sediment, phosphorus, nitrogen, organics, fertilizers, pesticides, yard waste,
surfactants, hydrocarbons, pH, and toxic compounds. The targeted audiences include residential,
commercial and institutional. The general messages promoted on the web pages are street to
stream, only rain should go down the storm drain, and be a Water Watcher/Volunteer. The web
pages also provide contacts for reporting pollution problems/concerns and submitting questions
to staff. During FY2019, Google Analytics showed CMSWS’s web pages had 376,617 page
views, which is an increase of 36.66% from the 275,595 page views in FY2018. This increase is
attributed to the increase in social posts and all collateral including the website, and with direct
links where possible. The pages most often visited were the Floodplains and Maps, the
Homepage, and The Big Spring Clean page. For Industrial/ Commercial Education, staff
attended and presented at the Regional Stormwater Partnership of the Carolinas meeting on
Storm Water Pollution Prevention (SWPP) service requests. Car maintenance BMP posters were
distributed during routine inspections and service requests and also at several auto body shops
throughout the county.

During FY2019, a media campaign was developed and implemented to reach residential,
commercial, and institutional audiences with information regarding reporting pollution,
volunteering, and flood safety in the Phase I and Phase II jurisdictions. The campaign included
television, radio, online, print, and Out-of-Home ads as well as social media (Facebook, Twitter,
Instagram and YouTube). Out-of-Home ads included the 4th Street Garage banner promoting the
annual Big Spring Clean and a banner promoting Flood Safety. Print ads included five (5)
Utility Bill Inserts (UBIs). UBIs are two-sided and cover storm water related topics such as
flooding, living in floodplains, storm water pollution indicators, preventing and reporting storm
water pollution, volunteering, etc. During FY2019, UBI messages were mailed to 255,000
customers in Charlotte-Mecklenburg once a month for five (5) months for a total of 1,275,000
contacts. A summary of the 2019 media campaign is provided below.

During FY2019, the BMPs implemented for the Public Education and Outreach Program were
evaluated and found to be effective at reducing non-point source pollutant loading to the
receiving streams of TMDL watersheds to the maximum extent practicable fulfilling the
11
requirements of the Phase II Permit and SWQMPP. Therefore, these BMPs will continue to be
used in FY2020 to comply with TMDL requirements.
2.2.2 Public Involvement and Participation (Section 4 of SWQMPP)
The following existing public involvement and participation activities have been identified as
suitable for addressing the pollutants of concern in the TMDL watersheds. These BMPs will

Volunteer Appreciation - In FY2019, the number of volunteers with CMSWS for the Phase I and
Phase II jurisdictions grew to such a large number it was no longer feasible to hold a specific
appreciation event without excluding a large number of volunteers due to budget constraints.
Therefore, CMSWS developed a “Thank You” campaign that recognized an overall “Volunteer
of the Year” along with recognizing a volunteer from each of our volunteer programs, including
Adopt-A-Stream and Storm Drain Marking. As a part of the campaign, car magnets were
designed and given out to all volunteers at events. The magnets promote clean water, while also
help to increase awareness of our programs. T-shirts were designed for the volunteers of the
year with the same advertising strategy in mind. Each volunteer of the year group was the focus
of a newsletter that went out to all volunteers. Newsletter recipients were posted on all social
media channels.
During FY2019, the BMPs implemented for the Public Involvement and Participation Program
were evaluated and found to be effective at reducing non-point source pollutant loading to the
receiving streams of TMDL watersheds to the maximum extent practicable fulfilling the
requirements of the Phase II Permit and SWQMPP. Therefore, these BMPs will continue to be
used in FY2020 to comply with TMDL requirements.
2.2.3 Illicit Discharge Detection and Elimination (IDDE) (Section 5 of SWQMPP)
The following existing IDDE activities have been identified as suitable for addressing the
pollutants of concern in the TMDL watersheds. These BMPs will address impaired waters by
14
identifying and eliminating sources of the pollutants of concern. During FY2019, these BMPs
were effectively implemented in the Phase I and Phase II jurisdictions in Mecklenburg County.
1. Storm Sewer System Mapping
2. Responding to Citizen Requests for Service
3. Enforcement of Pollution Control Ordinances
4. Conducting Facility Inspections
5. Performing Water Quality Monitoring Activities
6. Implementing the Illicit Discharge Elimination Program (IDEP)
7. Conducting Stream Walks & Dry Weather Flow Investigations
Storm Sewer System Mapping and Dry Weather Flow Investigations - ESRI Arc GIS is used to
identify new outfalls and track outfall inspections. In FY2019, written SOPs were reviewed,
updated as necessary and staff was trained in the use of a new GIS layer for performing outfall
inspections of existing features and to add new outfalls while performing inspections using the
mobile ESRI Arc GIS. During FY2019, 50 outfalls were inspected in the Phase II jurisdictions.
No illicit discharges or other sources of pollution were identified as a result of these inspections.
In addition, 174 new outfalls and 174 new inlets were added to the storm sewer inventory for
Phase II jurisdictions with many of them located in TMDL watersheds. With these additional
points, the total current inventory in Phase II jurisdictions/entities is 7,051 outlets and 34,623
inlets. Data is available to staff through the Cityworks database.
Responding to Citizen Requests for Service - During FY2019, staff responded to 123 service
requests regarding potential water quality problems in the Phase II jurisdictions. Ten (10) of
these service requests were emergency responses. The most common type of service requests
other than land development and buffer issues, involved the discharge and/or dumping of
potential surface water/storm water pollutants. The most common pollutants observed were:
• Petroleum Fuels = 11
• Sewage = 12
• Sediment = 5
• Wash water = 4
• Motor Oil = 5
As a result of the 123 service requests responded to there were a total of 56 problems detected
and 56 problems corrected in Phase II jurisdictions during FY2019. Table 9 below provides data
regarding the number and type of service requests received by category in each of the Phase II
jurisdictions.

Routine Water Quality Monitoring Activities - During FY2019, CMSWS performed continuous
automated monitoring at seven (7) sites (referred to as the Continuous Monitoring and Alert
Notification Network or CMANN) in the Phase II jurisdictions resulting in the collection of
290,022 QA/QC accepted data points (~86.1% data acceptance rate). All data collected was
evaluated for the identification of potential pollution problems and general water quality trends.
Current data can be observed on the following website: http://cmann.mecknc.gov. CMANN data
is used to help calculate the Stream Use Support Index (SUSI), which is a general indicator of
water quality conditions in our streams. This index was made available to the public on the
website as follows: http://stormwater.charmeck.org (select “Water Quality” at the top of the
page). In fiscal year 2019, CMSWS CMANN equipment did not observe or detect any pollution
problems in the Phase 2 jurisdictions.

During FY2019, Fixed Interval Monitoring was conducted on the 2nd Tuesday of every month at
10 sites throughout the Phase II jurisdictions. At each site, samples were collected and analyzed
for 17 water quality parameters as follows: ammonia-nitrogen, fecal coliform bacteria, total
kjeldahl nitrogen, nitrate/nitrite, total suspended solids, total phosphorus, enterococcus, e. coli,
turbidity, suspended sediment, magnesium, calcium, hardness, and copper (dissolved). Lead
(dissolved), chromium (total), and zinc (dissolved) were collected in the first month of each
quarter. Thirty-one (31) baseflow action level exceedances were detected during the year.
MC40C is immediately downstream of active greenway construction, such that turbidity and
associated pollutants persist due to pump around systems and earth work. Exceedances of total
phosphorus at MY14 and MY9 are associated with package wastewater treatment facilities in the
watershed. Fixed Interval Monitoring is also performed in the Phase I jurisdiction at 23
locations. Table 15 identifies the baseflow Action and Watch level exceedances identified in
TMDL watersheds in the Phase I and Phase II jurisdictions through Fixed Interval Monitoring
during FY2019. For all exceedances, follow up inspections were performed and pollution

Illicit Discharge Elimination Program (IDEP) – The purpose of the Illicit Discharge Elimination
Program (IDEP) program is to support and enhance Illicit Discharge Detection and Elimination
(IDDE) efforts in Mecklenburg County. The identification of pollution sources is accomplished
by investigating business corridors and industrial facilities in Mecklenburg County. During
FY2019, a total of seventeen (17) storm water outfalls were inspected under IDEP in Phase II
and one (1) Notice of Violation was issued. In addition, seven (7) facilities were inspected under
IDEP in Phase II during FY2019. All industrial facilities inspected were NPDES permitted.
Several of these inspections were conducted in TMDL watersheds.
Stream Walks – During FY2019, staff walked approximately 58.62 stream miles in the Phase II
jurisdictions, including 51.78 in the Towns and 6.84 miles in the ETJ areas located in the County
(see Figure 2). The following miles were assessed within each municipal boundary: 27.10 in
Matthews, 22.73 in Mint Hill, 1.86 in Pineville, and 0.08 in Stallings. 157 features were mapped
in Matthews, 95 in Mint Hill, 4 in Pineville, 3 in Stallings, and 25 points were mapped in the
ETJ. In all, there were 284 points or features recorded, 63 outfalls inspected, 151 new outfalls
identified, and 103 fecal coliform samples collected. Seven (7) of these samples resulted in
bacteria action level exceedances (>3000 col/100ml). No exceedances above the action level for
total phosphorus were detected (0.50 ppm). Two (2) buffer/floodplain disturbances were
identified and reported and followed up on. No dry weather flows or pollution sources were
observed during FY2019 Phase II stream walk activities.
Stream walk activities are also performed in the Phase I jurisdiction. Figure 2 identifies the
basins that were walked during FY2019 in the Phase I and Phase II jurisdictions. Table 16

In FY2015, a video entitled “Water Pollution: What to do?” was develop to train municipal
employees who have the potential to observe a water quality problem on the actions necessary to
eliminate pollution sources. The video teaches what pollutants can look like, and provides the
proper contacts to report pollution issues. In FY2015, the video was pushed out to the Towns
and CMS. In FY16, CPCC and select Mecklenburg County departments received the training,
including DSS, Environmental Health, Code Enforcement, Solid Waste, Air Quality, Parks and
22
Recreation, and the Sheriff’s department. As of the end of FY2019, 858 county employees from
select departments had completed the training.
During FY2019, the BMPs implemented for the Illicit Discharge Detection and Elimination
Program were evaluated and found to be effective at reducing non-point source pollutant loading
to the receiving streams of TMDL watersheds to the maximum extent practicable fulfilling the
requirements of the Phase II Permit and SWQMPP. Therefore, these BMPs will continue to be
used in FY2020 to comply with TMDL requirements.
2.2.4 Fats, Oils and Grease 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. This effort helps to reduce
clogging and blockages in the system and prevent SSOs, 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 FY2020.
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
the sanitary sewer system and correction of problems and illegal practices. Ensuring that the
system is used properly will help prevent leaks and overflows as well as upsets at wastewater
treatment plants thus helping control the TMDL pollutants of concern. This ordinance has
proven to be effective and will continue to be implemented in FY2020.
2.2.6 Sanitary Sewer System Inspections and Maintenance
Charlotte Water conducts inspections and maintenance of various components of
the sanitary sewer system in the Phase I and Phase II jurisdictions to ensure proper operating
function and prevent leaks and overflows. These include food service grease trap inspections,
commercial oil/water separator inspections, sanitary sewer line root control and cleaning, sewer
line right-of-way clearing and maintenance, and lift station inspection and maintenance.
Ensuring that the system is used properly inspected and maintained will help prevent leaks and
overflows as well as upsets at wastewater treatment plants thus helping control the TMDL
pollutants of concern. These inspection and maintenance efforts have proven to be effective and
will continue to be implemented in FY2020.
2.2.7 SSO Rapid Response
Charlotte Water maintains a rapid response program designed to quickly and efficiently respond
to sanitary sewer overflows, thus reducing the discharge of pollutants to the MEP and helping
control the TMDL pollutants of concern in the Phase I and Phase II jurisdictions. These program
has proven to be effective and will continue to be implemented in FY2020.

Section 3: Current TMDL Monitoring Strategies
CMSWS conducts fixed interval stream monitoring on the second Tuesday of every month at 33
locations across the county (see Figure 3) in the Phase I and Phase II jurisdictions many of which
are located in or immediately downstream of the TMDL watersheds that are shown in Figure 1.
At each site, samples are collected and analyzed for 17 water quality parameters as follows:
ammonia-nitrogen, fecal coliform bacteria, total kjeldahl nitrogen, nitrate/nitrite, total suspended
solids, total phosphorus, enterococcus, 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
monitoring for benthic macroinvertebrates in the Phase I and Phase II jurisdictions at these 33
stream monitoring locations. CMSWS maintains a Continuous Monitoring and Alert
Notification Network or CMANN at 32 of the 33 fixed interval monitoring locations shown in
Figure 3 that 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 13
parameters: secchi depth, temperature, dissolved oxygen, conductivity, pH, fecal coliform
bacteria, alkalinity, ammonia nitrogen, nitrate + nitrite, total kjeldahl nitrogen, total phosphorus,
turbidity, and chlorophyll a. Monitoring for the following 12 parameters is performed twice a
year: copper, chromium, lead, zinc, mercury, manganese, arsenic, cadmium, nickel, selenium,
aluminum, and iron. 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 are done 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, which includes the Rocky River and Goose
Creek impaired for fecal coliform bacteria and Lake Wylie impaired for chlorophyll-a (see Table
1).

Figure 3: Water Quality Monitoring Locations in Mecklenburg County
3.1 Rocky River Fecal Coliform Monitoring and Land Use Evaluation
As identified in Table 1, 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 the approved NC 2018 305(b) report, the Rocky River is
currently not meeting the fecal coliform criteria. Mecklenburg County has been assigned
28
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 was 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 landuse data from the County GIS Department back
to 2011 and continues to update this data annually (see Table 19). Between 2017 and 2018 there
was a 3.2% increase in residential impervious cover to a total of 15.69 acres. The commercial
impervious cover remained unchanged at 0.33 acres for a total amount of impervious cover in the
watershed at 16.02 acres. Compared to the total area of the watershed at 747 acres, the amount
of imperious cover is at 2.14%, which is an increase of 1.95% since 2011. The number of
outfalls is unchanged from 2017 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.

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 the approved NC 2018 305(b) report, the
two (2) TMDL segments of Goose Creek are currently meeting the fecal coliform criteria.
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 2018, CMSWS fecal coliform counts at this station ranged from 100 to 10,800
CFU/100 ml, with 11 out of 19 (58%) in compliance (≤400 CFU/100 ml). No pollution sources
were identified as a result of the water quality monitoring in the Goose Creek TMDL watershed
during FY2018. Table 21 provides a summary of this data from 2014 through 2018. Figures 6
and 7 provide a comparison of fecal coliform data indicating some improvement over time.

3.3 Lake Wylie Chlorophyll-A Monitoring
As identified in Table 1, two (2) sections of Lake Wylie in Mecklenburg County (AU Numbers
11-122 and 11-(123.5)a) are subject to a chlorophyll-a TMDL approved on February 5, 1996 that
does not include a WLA assigned to storm water. According the approved NC 2018 305(b)
report, the two (2) TMDL segments of Lake Wylie are currently meeting the chlorophyll a
criteria. Mecklenburg County has been assigned responsibility for compliance with this TMDL
on behalf of the Phase I and Phase II jurisdictions in Charlotte-Mecklenburg. All 69 Lake Wylie
Chlorophyll-a samples collected by CMSWS in 2018 were below 40 ug/l. Figures 8 and 9
provide a comparison of fecal coliform data indicating improvement over time.

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, an analysis of mercury data is not
included in this document. Also for this reason, this document does not include compliance
measures for this TMDL.
3.5 Effectiveness of BMPs Based on Data Analysis
Based on the above described assessments of data collected in the TMDL watersheds, a general
improvement in water quality is identified; therefore, it is determined that the current BMPs are
effective at identifying and eliminating pollution sources in compliance with TMDL
requirements and that these BMPs will continue to be implemented in FY2020. Additional
structural and/or non-structural BMPs will be implemented as described in Section 4 to further
enhance TMDL compliance.
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 section and identify
and implement additional BMPs as necessary to effectively address impaired waters. The
following subsections describe the additional BMPs implemented in FY2019, as well as those
planned for implementation in 2019 along with an implementation timeline, and a brief
explanation as to how these additional BMPs will address impaired waters.
4.1 Additional BMPs Implemented for the Rocky River TMDL in FY2019
During FY2019, the following additional activities were completed to reduce fecal coliform
bacteria levels and enhance water quality in the Rocky River watershed:
1. Monthly water quality monitoring, including sampling for fecal coliform bacteria,
continued at site MY1B (West Branch of the Rocky River at River Ford Drive) located
upstream of the TMDL watershed in Mecklenburg County. No exceedances of water
quality standards were detected . No pollution sources were identified as a result of this
monitoring.
2. On December 15, 2018, Health Department records were reviewed and no failed septic
systems were identified.
3. On October 24, 2018, 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. Design plans are under development for the restoration of a section of the Rocky River in
the TMDL water in Mecklenburg County.
4.2 Additional BMPs Implemented for the Goose Creek TMDL in FY2019
During FY2019, the following additional activities were completed to reduce fecal coliform
bacteria levels and enhance water quality in the Goose Creek watershed:
33
1. Routine fixed interval monitoring was conducted monthly at sites MY-9 (Goose Creek –
Stevens Mill Road) and MY-14 (Duck Creek – Tara Oaks Lane). Monthly samples were
analyzed for 16 parameters including fecal coliform, E. Coli, and Enterococcus bacteria.
Monitoring results are described in Section 3.2.
2. Beginning on November 1, 2018 and concluding on May 16, 2019, extensive monitoring
for fecal coliform bacteria was performed throughout the Goose Creek watershed during
stream walk activities. No pollution sources were detected.
3. On December 15, 2018, Health Department records were reviewed and no failed septic
systems were identified.
4.3 Additional BMPs to be Implemented in FY2020
During FY2020, the following additional BMPs will be implemented in the Rocky River Goose
Creek watersheds to reduce fecal coliform bacteria levels and enhance water quality:
1. Routine fixed interval monitoring will continue to be performed monthly at MY-9 on
Goose Creek at Stevens Mill Road, MY-14 on Duck Creek at Tara Oaks Lane, and at
MY1B located upstream of the Rocky River TMDL watershed. Monthly samples will be
analyzed for 16 parameters including fecal coliform, E. Coli, and Enterococcus bacteria.
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.
2. By June 30, 2020, 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.
3. By June 30, 2020, 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.
4. In November 2019, design and permitting will be completed for the restoration of a 2
mile section of the Rocky River. Currently, the Rocky River is severely eroded by storm
water flows that eat away at the stream banks. The restoration project will stabilize the
stream banks to reduce erosion and improve water quality in the creek.
5. By May 2020, construction will be completed on the restoration of a 2.3 miles section of
Stevens Creek in the Goose Creek TMDL watershed. Currently, Stevens Creek is
severely eroded by storm water flows that eat away at the stream banks. The restoration
project will stabilize the stream banks to reduce erosion and improve water quality in the
creek.
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.
