Purpose
The purpose of this Water Quality Recovery Program (WQRP) is to reduce the levels ofturbidity, to
the maximum extent practicable, in accordance with the assigned MS4 NPDES regulated Waste
Load Allocation (WLA) identified in the approved Turbidity Totai Maximum Daily Load (TMDL)
for Muddy Creek.
The goals of this Water Quality Recovery Program (WQRP) are to identify BMP's, management
strategies, time frames and costs necessary to address the MS4 NPDES regulated Waste Load
Allocation (WLA) identified in the TMDL, which in turn will assist in returning the impaired
segments to compliance with state water quality standards.
Background
Muddy Creek is located within the Yadkin -Pee Dee River Basin. The Muddy Creek Watershed is
located in the following counties: Stokes, Forsyth, and Davidson. The Village of'Clemmons is one
of the smaller MS4 within the Muddy Creek Watershed; Muddy Creek drains in a southeastern
direction within the Village's municipal boundaries. The section of Muddy Creek subject to The
Village of Clemmons stormwater runoff was divided into two sub watersheds (Upper and Lower)
with Interstate 40 serving as the dividing line. According to the Village's GIS database, the Muddy
Creek Watershed within Clemmons has a drainage area of 5.34 square miles and 29.28 linear miles
of perennial streams.
The Muddy Creek Watershed is located within hydrologic unit 03040101 13 and signed an
Assessment Unit of 12-94-(0.5)c. Muddy Creek is currently impaired for excessive levels of total
suspended solids (TSS). The impaired segment of Muddy Creek within the influence of the Village
of Clemmons originates at the intersection of Muddy Creek with the Northfork Southern Railroad at
the northeastern corner of the Keith Hasting property, parcel identification number of 5892-96-
3418.00 and extends north to approximately 100 feet north of the northwestern corner of'the
property owned by Johnny Weisner, parcel identification number of 5894-53-5787.00. The
impairment length of Muddy Creek is 3.8 miles (NCDENR 201 1).
The 2008 North Carolina Water Quality Assessment and Impaired Water List (integrated 305(b) and
303(d) report) identified Muddy Creek in the Yadkin River Basin as impaired due to aquatic life
degradation. Standard violations of elevated TSS levels were recorded by North Carolina Division
of Water Quality (NCDWQ).
The Muddy Creek Turbidity TMDL document was submitted by the North Carolina Department of
Environment and Natural Resources (NCDENR), NCDWQ to EPA on October 19, 2011. EPA
approved the Muddy Creek Turbidity TMDL on November 17, 2011.
Muddy Creek Watershed Maps
Figure 1 shows an overview of Muddy Creek Watershed with the jurisdiction limits for Village of
Clemmons highlighted. The Village's Watershed has been divided into two sections for visual
simplicity with Interstate 40 being the division line. Figures 2A — 5B reflect the outfall inventory,
stormwater infrastructure, designated land use, and BMP locations within the subject drainage area.

Program Implementation Schedule
Program elements and associated activities identified in the WQRP will be conducted in various
permit years within the current and future MS4 NPDES 5-year pcnnit terns. The proposed
implementation schedule for this WQRP is as fbllows:
WQRP — End Year 1 (Nov. 30, 2012).
• Identify the purpose and goals of the TMDL Water Quality Recovery Program (WQRP).
• Identify the watershed and provide bricf'description.
• Identify locationand map major known outfalls in TMDL watershed.
• Develop and submit a schedule to discover and locate all other MS4 major outfalls within
the MS4 jurisdictional area that may be discharging the pollutant(s) of concern to the
impaired stream segments, to their tributaries, and to segments and tributaries within the
watershed contributing to the impaired segments.
WQRP — End Year 2 (Nov. 30, 2013)
• Assemble a team ofstaff representatives from affected municipal departments.
Establish a Public Education and Outreach Program.
• Describe existing measures being implemented by the Village of Clemmons to enhance
water quality to the watershed.

determine current TSS levels. Collect and analysis samples during normal and high flow
events.
Develop a WQRP monitoring plan for the pollutant ofconcern and submit to DWQ for
approval.
Develop non-structural and structural BMP strategies by the years end to enhance water
quality and provide a written summary of how the additional measures will heighten water
quality.
Permit 9NC5000410-2012 WaterOualicy Recovery Ilan 13

WQRP —`End Year 4 (Nov. 30, 2015)
Conduct incremental success analysis of implemented BMPs from previous years.
Develop a schedule to implement appropriate regulatory strategies, non-structural BMPs,
and structural BMPs to control the pollutant(s) of concern to the maximum extent
practicable.
Conduct an annual assessment of effectiveness ofTMDL Reduction Program and submit a
report to the Division for Years I through 4 and annually thereafter or as required.
Pollutant of Concern
The pollutant of concern and the focus of this WQRP is the MS4 WLA for turbidity. The Village of
Clemmons will reduce the total discharge of total suspended solids from the MS4 to the maximum
extent practicable.
Potential sources of turbidity from nonpoint sources are forests, agricultural lands, land disturbance,
urban runoff, and stream channel erosion. Surface runoff is the main carrier of sediments from
forests and agricultural land (NCDENR 2011),
Urbanization increases the amount of sediment transport to receiving waters. ]mpervious urban
features such as: roads, bridges, parking lots, and buildings prevent rainwater from infiltrating into
the ground. In impervious areas, rainwater remains above the ground, gathers sediments and solids,
and discharges into local waterways (NCDENR 2011).
Point sources of turbidity consist primarily of industries, wastewater treatment plants, and municipal
separate storm sewer systems (MS4). The MS4 can quickly direct urban runoff from roads and
other impervious surfaces.
When rainwater leaves the MS4 and discharges into a stream, large volumes of swift -moving runoff
erode strearn banks, damage streamside vegetation, and widen stream channels. The amount of
sediment depends on erodibility of soils, types of surfaces, vegetation, rainfall intensity, and
existence and types of stormwater managernent devices (NCDENR 2011).
MS4 Major Outfall Identification
During WQRP Year 1, a watershed map will be developed detailing the location of'known major
outfalls in relationship to receiving streams (as defined in the MS4 NPDES permit) within the
NPDES MS4 jurisdictional area that have the possibility of discharging the pollutant of concern to
the impaired segments as defined by the MS4 permit, its tributaries or to segments and tributaries
within the watershed contributing to the impaired segments.
During WQRP Year 1, a schedule will be developed to locate the position of other major outfalls not
indicated within the watershed that may discharge the pollutant of concern to the impaired segment,
its tributaries or to segments and tributaries.
Permit 4NCS000410 — 2012 Water Quality Recover} Plali 14

TMDL WQRP Implementation Team
During WQRP Year 2, a team of staff representatives will be assembled from municipal agencies
that conduct activities within the TMDL watershed. In addition, other potential staff resources will
be identified as necessary to serve on TMDL WQRP Implementation Team. Based on the pollutant
ofconcern, municipal agencies could include Public Works, Stormwater, Planning Department, and
City/County Erosion Control Section, and others. The NPDES MS4 entity will be responsible for
interpreting data, judging BMP effectiveness, reporting to DWQ, and coordinating activities and
reviews with the Implementation Team to meet the components and goals of the WQRP.
Public Education and Outreach Program
During WQRP Year 2, a Public Education and Outreach Program will be established to provide
information concerning the WQRP. At a minimum, a webpage will be added to the Village of
Clemmons current website to disseminate information and results. In addition, the program may
include items such as:
• Pollutant of'concern specific information in brochures, bill inserts, etc.
• Adopt -a -Stream or Storm Drain Marking activities
• Presentations to groups
• Participation in public events
BMP Identification & Assessment
During WQRP Year 2, the Village will describe existing best management practices (BMPs) that
enhance water quality within the Muddy Creek Watershed. In order to justify the rationale of the
selected BMPs for mitigating total suspended solids releases to surface waters, the Village will
provide explanations of these existing measures.
Initial BMP strategies may include:
• Increased street sweeping activities.
• Targeted public education and outreach programs.
• Development of a WQRP specific webpage.
• Targeted public participation programs.
• Increased IDDE efforts for construction site activities.
• Existing stream bank stabilization projects.
• Modification of existing strategieslrequiremcnts for structural BMPs.
'rhe Village will begin collecting samples from targeted outfalls at different storm events to provide
a baseline of existing turbidly levels in'order to confirm the effectiveness of future implemented
water quality measures. 'rhe collected data will be analyzed to determine any possible existing
trends.
Permit 4NCS000410-2012 Water Quality Recovery Plan 15

During WQRP Year 3, an additional assessment will evaluate if any additional BMPs should be
employed to address the MS4 NPDES regulated Waste Load Allocation identified in the TMDL tc
the maximum extent practicable. This assessment will be based on factors such as cost/benefit
analysis, MEP standards, water quality data trends, status of activities & accomplishments relative
to defined end -point in the WQRP, etc.
Monitoring Plan
During WQRP Year 3, a monitoring plan will be developed for turbidity and TSS and submitted to
DWQ for approval.
The goals of the WQRP monitoring plan will be to:
1. Identify the significant sources of the pollutant of concern related to MS4 regulated WLA.
2. Evaluate the performance of BMPS utilized in the WQRP, where possible.
3. Assess progress toward the goals of the WQRP at the TMDL identified compliance point.
The monitoring plan will include components such as:
1. Written description and GIS map of sample locations
2. Monitoring methods
3. Sample type and frequency
4. Seasonal considerations
5. Sample analytical methods
6. Quality assurance
7. Record keeping
The monitoring plan shall include in -stream and/or major outfall monitoring at locations deemed
necessary to support assessment of activities in the WQRP to address the MS4 NPDES regulated
Waste Load Allocation (WLA) identified in the TMDL.
In lieu of developing a monitoring plan, the Village of Clemmons may request a waiver from the
Division if a program evaluation confirms that current (and proposed) measures are enhancing water
quality within the Muddy Creek Watershed. This request will be contingent upon the Village's
ability to implement obtainable water quality measures to the maximum extent practical.
Implementation of the Plan to the Maximum Extent Practicable
During WQRP Year 4, an assessment of available data, BMP strategies, cost benefit analysis, and
WQRP effectiveness will be conducted and utilized to define additional measures that will further
enhance water quality within the Muddy Creek Watershed. In addition, the Village will create an
implementation schedule for the identified measures.
As part of the Village's assessment.. the appropriate water quality measure will be evaluated for its
percent of improvement for reducing the MS4's contribution to Muddy Creek. The results of the
analysis and definition will be used to prioritize locally limited funding aimed at elimination of the
greatest MS4 waste load allocation reduction for the least amount of expenditure.
Permit 9NCS000410 — 2012 Water Quality Recovery Plan 16

Incremental Success
After water quality measures have been implemented, the Village of Clemmons will evaluate each
measure's effectiveness in mitigating TSS loading to Muddy Creek. The initial phase of reducing
TSS loading entaiis the tabulation of additional workload measures in order to validate program
success. Examples of these measures may include:
• Targeted municipal storm system maintenance activities
• Increased construction site inspections where applicable
• Targeted monitoring and complaint response
• Increased street sweeping activities
Later stages ofthe water quality recovery program will most likely encompass the implementation
ol'progressive structural BMPs for TSS reduction. Since the greatest loading of TSS to Muddy
Creek occurs during high flow events, BMPs may need to be designed to accommodate these flows
in order to achieve targefed reduction of TSS concentrations. If possible an evaluation ofthe.
existing BMPs performance and the introduction of additional BMP strategies may need to be
implemented to achieve better results.
WQRP Reporting
Activities and assessments conducted under the WQRP will be reported to DWQ along with the
annual report submitted each year for the MS4 NPDES permit. Annual compliance with the WQRP
implementation schedule will constitute compliance with the overall WQRP. The annual report for the
WQRP may include, as applicable per WQRP schedule, the following:
• The initial WQRP and subsequent components based on Implementation Schedule.
• Discussion on the status ofthe WQRP and schedule.
• Discussion of activities conducted for WQRP and progress made toward meeting program
elements during report year.
• Annual approximate cost of WQRP.
• An assessment ofavailable data collected under the monitoring plan for TSS.
• An assessment of the performance of BMPs employed, where possible.
• A map showing the location of major outfalls in "TMDL watersheds with the potential for
discharging the pollutant ofconcern.
• A schedule for locating currently other major outfalls that may potentially discharge the POC
in TMDL watersheds.
• Identification of in -stream and outfali sampling locations.
• Identification of additional BMPs, if necessary.
• Monitoring data that was collected during the WQRP year
Following any review and comment by the Division on the TMDL Water Quality Recovery
Program, the permittee shall incorporate any necessary changes into the program. The permittee
shall incorporate the revised "TMDL WQRP into the Stormwater Management Plan.

Subject: NPDES Phase II Stormwater Program
Gary M. Looper:
In 1990 the U.S. Environmental Protection Agency's (EPA) Phase I stormwater program was promulgated under the
Clean Water Act. Phase I relies on National Pollutant discharge Elimination System (NPDES) permit coverage to
address stormwater runoff from: (1) "medium" and "large" municipal separate storm sewer systems (MS4s) generally
serving populations of 100,000 or greater, (2) construction activity disturbing 5 acres of land or greater, and (3) ten
categories of industrial activity. The NPDES Stormwater Phase I1 Final Rule was promulgated in December 1999 and is
the next step in EPA's effort to preserve, protect, and improve the Nation's water resources from polluted storm water
runoff. The Phase 11 program expands the Phase 1 program by requiring additional operators of MS4s in urbanized areas
and operators of small construction sites, through the use of NPDES permits, to implement programs and practices to
control stormwater runoff. Phase I1 is intended to further reduce adverse impacts to water quality and aquatic habitat by
instituting the use of controls on the unregulated sources of stormwater discharges that have the greatest likelihood of
causing continued environmental degradation.
The NPDES Stormwater Phase II Final Rule requires nationwide coverage of all operators of small MS4s that are
located within the boundaries of a Bureau of the Census defined "urbanized area" based on the latest decennial Census.
We are writing to you to remind you that the Village of Clemmons has been identified as being located within a census
designated urbanized area in both the 1990 and 2000 decennial census. As a regulated community, you are required to
develop a stormwater management program and apply for stormwater permit coverage, if you own and operate a small
MS4 or file a certification that the Village of Clemmons does not own or operate a small MS4. The deadline for
submitting your application package or non -ownership certification is March 10, 2003. Application and certification
documents, as well as additional information on the NPDES stormwater program, are available for download at our web
site . Our web address is http://h2o.enr.state.nc.us/su/stormwater.htmi. You may also contact us for hard copies of the
documents. If you have any questions about this letter, please feel free to contact me (919-733-5083, ext.525) or Darren
