Subject: Draft NPDES Stormwater Permit
Permit No. NCS000368
Powerlab, Inc.
Mecklenburg County
Dear Mr. Tunnell:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters (Lead and pH) have been added to this permit.
2. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part II Section B. The permittee must also document the total precipitation for each event. If no discharge
occurs during the sampling period, the permittee must submit a monitoring report indicating "No Flow"
within 30 days of the end of the six-month sampling period. Additionally, samples must be taken a
minimum of 60 days apart, as specified in Table 2.
3. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark
values require the permittee to increase monitoring, increase management actions, increase record
keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program. If the
sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within
two weeks and implementation of a mitigation plan within two months. If during the term of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfall two times in a row (consecutive), then. the facility shall follow the
Tier 2 guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute
monthly monitoring for all parameters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
4. You are required to collect all of the analytical -and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of
representative outfall status.
5. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)

7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. Monitoring for TPH has replaced Oil & Grease. This requirement appears in
all Individual Stormwater permits, however it only applies to facilities that do vehicle maintenance. If the
facility begins vehicle maintenance during the permitted timeframe then the requirements shall apply.
Other permit changes:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants
in each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part 11 Section A.
More details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II
Section A. The plan must also be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
6. In addition to submitting two signed copies of DMRs to Central Files, a separate signed Annual Summary
DMR copy must be submitted to the local DWQ Regional Office by March 1 of each year.
PIease submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

2. General Observations: See other notes below.
3. Impairment: Stream impaired for Copper, Ecological/Biological Integrity (Benthos, FishCom), fecal Coliform
and Zinc -- perhaps only parameter that is relevant is Ecological/Biological Integrity. TMDL has been issued for
Turbidity and Fecal coliforrn — not applicable to this site.
4. Threatened and Endangered: No T&E Species found near site.
5. Location: (If applicable, i.e the facility was difficult to locate or is on the boundary of a receiving water, etc)
6. Industrial Changes Since Previous Permit: Because of business conditions, this Powerlab facility closed from
March 2009-August 2010, and did not monitor. To our knowledge, this plant did not receive permission from
DWQ or DWQ RO to stop monitoring at this point. During the shutdown period, two of the six lead oxide
production units were removed; the remaining four are currently in operation. They have not changed their
process or raw materials, and their storage practices remain the same. They state these changes have not effected
stormwater runoff.
Outfall 3 is "now used as process wastewater" — no discharge.
7. Analytical Monitoring Notes: Lead is consistently above benchmark values when it has been sampled. pH
should have been sampled but apparently was not. No sampling took place at all during the shutdown period.
See conversation notes with permittee for more information,
Previous staff report indicate that Lead was a concern — perhaps especially from loading dock area, which may
drain to surface waters. Additionally they were asked to sample pH because of its use in interpreting metals
toxicity, but have not. Additionally, previous staff report indicates that sampling was not done for all time
periods.
MSGP lists Aluminum, Iron, and Nitrite -Nitrogen as testing parameters; however these are not applicable to this
site.

8. Qualitative Monitoring Notes: From submitted data, Qualitative monitoring appears to be exemplary in terms of quality: all color was listed as clear;
Odor as none; clarity, floating solids and suspended solids were listed as "I"; No foam or oil sheen were present.

Revised Permit Recommendations: Analytical Monitoring:
l . No parameters will be added or removed — however Tiered system will be in place and Lead and pH will be kept
in permit.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part II
Section B. The permittee must also document the total precipitation for each event. if no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row. (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part lI Section B. Qualitative monitoring is required regardless of representative
outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to.
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part lI Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part Il Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information
is provided in Part I Section A.

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each storm water discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

Dear Mr. Bennett:
Please find attached Powerlab's renewal application package for our stormwater discharge permit
NCS000368. I apologize for this application not being summited on time. As I explained by telephone to
Brian Lowther of your office, Donald Rabon, who did the environmental reporting for our company,
passed away unexpectedly last November. I have been filling in in this capacity, and the letter from you
concerning this renewal was overlooked.
Our North Carolina facility was shut down in March of 2009 due to business conditions, and was
reopened in August of 2010; therefore, there is no data for this shutdown period.
As I have said, I am handling the responsibility for environmental reporting until Mr. Rabon is replaced.

Summary of Best Management Practices
Good Housekeeping
Powerlab practices good housekeeping measures to maintain a clean and orderly work
environment. A plant meeting is conducted every month in which good housekeeping
practices are discussed. At Powerlab, every employee has a job description, which
defines the activities he has to perform. Good housekeeping is a part of every
employee's job description and is practiced daily.
Operation and Maintenance - These practices ensure that processes and equipment are
working well.
• Conduct operations indoors so the potential for any oil drips and/or fuel oil leaks to
enter the storm water system have been minimized;
• Routine vehicle maintenance is performed off site by trained automotive technicians;
• Maintain clean and dry floors by using brooms, shovels, vacuum cleaners, and
cleaning machines;
• Regular pickup and disposal of garbage and recycled material;
• Make sure equipment (especially the pressurized conduit system) is working
properly;
• Routinely inspect for leaks or conditions that could lead to discharges of chemicals;
• Routinely inspect for contact of storm water with raw materials or finished products;
• Ensure that employees understand spill cleanup procedures.
Material Storage Practices - Improper storage can result in the release of materials or
chemicals that can cause storm water runoff pollution. Proper storage techniques
implemented at Powerlab's facility include:
• Providing adequate space to facilitate material transfer and easy access for
inspections;
Page 1 of 4

• Storing containers, drums, and bags away from direct traffic routes to prevent
accidental spills;
• Stacking containers according to manufacturers' instructions to avoid damaging the
containers;
• Storing containers indoors on pallets or similar devices to prevent corrosion of the
containers, which can result when containers come in contact with moisture on the
ground;
• Assigning the responsibility of hazardous materials inventory to a limited number of
people who are trained to handle hazardous materials.
Material Inventory Procedures - The Powerlab facility maintains an active list of all
chemical substances authorized/on-hand for the facility/workplace. Material Safety Data
Sheets (MSDS) for each chemical substance are also stored onsite and available for
employees. Some additional procedures implemented include:
• Label all containers to show the name and type of substance, stock number,
expiration date, health hazards, suggestions for handling, and first aid information;
• Clearly mark all hazardous materials that require special handling, storage, use, and
disposal considerations.
Employee Participation - Frequent and proper training of employees in good
housekeeping techniques reduces the possibility that the chemicals or equipment will be
mishandled. Motivating employees to reduce waste generation is another important
pollution prevention technique. Some methods employed for involving employees in
good housekeeping practices:
• Employees must keep themselves and their uniforms as free of dust as possible. They
are not to walk outside the plant with dirty plant shoes, as this could contaminate the
ground. Employees must vacuum the dust from their person and uniform before
entering the locker room and whenever necessary.
• Employees must shower before they leave the plant and place dirty clothes and safety
equipment in assigned dirty lockers at the plant.
• Incorporate information sessions on good housekeeping practices into the facility's
employee training program;
• Discuss good housekeeping at employee meetings.
Page 2 of 4

Preventive Maintenance
Preventive maintenance measures are conducted on equipment to decrease the occurrence
of mobile and stationary equipment spills. A list of measures implemented at the
Powerlab facility are identified below:
• Qualified maintenance personnel or machine operators, who evaluate the adequacy of
the equipment and make recommendations for repairs and improvements, conduct
preventative maintenance on equipment. Inspections of drums, pumps, and fittings
are conducted on a regular basis to identify leaks or defects, that might lead to a spill.
• Adjustments, repairs, or replacements of equipment are conducted as needed.
• Parking lots are inspected on a regular basis to detect spills or potential spill sources.
• The Facility Maintenance Supervisor maintains complete records on inspections, .
equipment, and systems. These records are kept with other visual inspection records.
• Powerlab maintains a well -lighted site with a secure fence around the perimeter in
order to keep unauthorized personnel out.
Inspections
Routine inspections are conducted of the finished and unfinished product storage area,
chemical storage area, load inglunloading area, waste management areas, equipment
storage area, and maintenance areas.
Spill Prevention and Response
Spill prevention is a major goal of Powerlab. To avoid possible accidental spills,
equipment is placed inside a covered building. The only possibility of spill is of an oil
spill from the trucks or material spill while loading or unloading.
Trucks are loaded or unloaded only when parked on a concrete driveway so that no
chemical percolates in the soil if spilled. Spill response equipment, is kept ready for use
at all times. Employees have been educated about spill cleaning methods in the routine
plant meetings.
The only materials loaded on trucks are dross and other lead -contaminated materials,
which are kept in labeled drums totally enclosed from all sides, and lead oxide, which is
mechanically conveyed to a totally enclosed truck.
Lead is the only material unloaded. It is not a hazard to the storm water runoff even if
spilled, because it is in solid metal form. All chemicals received at Powerlab are in
manufacturers' packing, which is usually in airtight containers.
Page 3 of 4

Sediment and Erosion Control
All areas exposed to storm water are either paved, or have grass/shrubs growing.
Additionally, there are no significant changes in elevation throughout the site to cause
storm water velocity problems.

Changes in Industrial Activities
Due to business conditions, this Powerlab facility was closed and mothballed in March of
2009. Production at this facility was resumed in August of 2010. During the shutdown period,
two of the six lead oxide production units were removed; the remaining four are currently in
operation. We have not changed our process or raw materials and our storage practices
remain the same. These changes in production in no way affect our stormwater runoff.

Description of Onsite Activities:
Powerlab, Inc takes lead ingots and melts them to produce a powder that will be used in battery production. Pure metallic lead
is oxidize d in reactor unit to form a dry bulk powder or lead oxide. The process equipment, conveying, bulk loading, and
storage hoppers are all under negative pressure. All process air and material handling equipment ventilation air is filtered by
baghouses and heap filters before being exhausted to the atmosphere. All storage of raw material, processing, and storage of
finished product is done inside the building.
The lead ingots are unloaded from trucks or occasionally from rail cars to inside storage of all ingots. The second loading dock
is used for loading the lead powder in to bulk hopper tankers for a transport to battery manufacturers. The delivery hoses (8"-
12" diameter) are connected to the top of the hopper tankers for loading the powder. Powerlab Inc in Winston Salem, NC is a
private company categorized under Lead Pigments: White Lead, Lead oxides, Lead Sulfate. Current estimates show this
company has an annual revenue of $5 to 10 million and employs a staff of approximately 10 to 19.

WASTEWATER FACILITY
3. Impairment: Stream impaired for Copper, Ecological/Biological Integrity (Benthos, FishCom), Fecal Coliform
and Zinc — perhaps only parameter that is relevant is Ecological/Biological Integrity. TMDL has been issued for
Turbidity and Fecal coliform — not applicable to this site.
4. Threatened and Endangered: No T&E Species found near site.
5. Location: (If applicable, i.e the facility was difficult to locate or is on the boundary of a receiving water, etc)
6. Industrial Changes Since Previous Permit: Because of business conditions, this Powerlab facility closed from
March 2009-August 2010, and did not monitor. To our knowledge, this plant did not receive permission from
DWQ or DWQ RO to stop monitoring at this point. During the shutdown period, two of the six lead oxide
production units were removed; the remaining four are currently in operation. They have not changed their
process or raw materials, and their storage practices remain the same. They state these changes have not effected
stormwater runoff.
Outfall 3 is "now used as process wastewater"— no discharge.
7. Analytical Monitoring Notes: Lead is consistently above benchmark values when it has been sampled. pH
should have been sampled but apparently was not. No sampling took place at all during the shutdown period.
See conversation notes with permittee for more information.
Previous staff report indicate that Lead was a concern — perhaps especially from loading dock area, which may
drain to surface waters. Additionally they were asked to sample pH because of its use in interpreting metals
toxicity, but have not. Additionally, previous staff report indicates that sampling was not done for all time
periods.
MSGP lists Aluminurn, Iron, and Nitrite -Nitrogen as testing parameters; however these are not applicable to this
site.

8. Qualitative Monitoring: From submitted data, Qualitative monitoring appears to be exemplary in terms of quality: all color was listed as clear;
Odor as none; clarity, floating solids and suspended solids were listed as "I'; No loam or oil sheen were present.

Revised Permit Recommendations: Analytical Monitoring:
I . No parameters will be added or removed — however Tiered system will be in place and Lead and pH will be kept
in permit.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part 11
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow' within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier I and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part 11 Section B. Qualitative monitoring is required regardless of representative
outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
I . Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfails have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A.
2_ Additional requirements for the Stormwater Management Plan have been specified in Part 11 Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part 11 Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part I1 Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information
is provided in Part I Section A.

RE: NCS000368 - Powerlab, Winston-Salem, NC
Dear Ms. Jones:
Here is the information I was unable to give you on Tuesday:
4. 1 found ph data for the following samples:
OutfallI Outfall2 Outfall3
April ]-June30,2007 7.35 7,64 7.50
Sept 1-Nov 30, 2007 6.10 5.40 5.25
April 1-June 30, 2008 7.06 6.97
Sept 1-Nov 30, 2008 6.34 4.51
We will be sure to obtain and report ph levels for future tests.
5. Outfall #3 was sealed off from running under the building and going into the ditch that runs behind the plant. There
is now a pit at outfall #3 with and sump pump in the pit used to pump rain water to a holding tub inside the plant and
the water is then used in the manufacturing process.
7. We are in the process of developing new housekeeping procedures to lower our runoff lead levels. We will keep you
informed. We will have the results from the last sampling within 10 days, and I will forward them to you.
9. Care is taken not to spill any material when loading a tanker. The loading area is covered and the pavement here
slopes toward the building so any spills can be captured and disposed of rather than the material getting into the
stormwater stream.
12. Our SPPP was revised in January 2008.
13. On October 5, 2009 we informed the Forsyth County Environmental Affairs Department that we were shutting
down this facility.
15. Outfall #1 is the runoff from the truck scale, employee parking area and dumpster area.
Outfall #2 handles the employee parking area and roof.
will be present for our October 111h inspection by Ron Boone. If there are further questions please give me a call.
Sincerely,
Forrest Tunnell

Discussions with permittee: Forrest Tunnell, 972-563-1477, September 20, 2011
1. Q: Is your address still 3352 Old Lexington Road, Winston-Salem, NC`?
a. A: that is the physical address. The corporate headquarters and mailing address are PO Box 913, Terrrell, TX
75160
2. Q: Can you describe your process please?
a. Make lead oxide, take block of pure lead, melt them, then introduce a stream of molten lead to a reactor
(cylindrical vessel), under specific conditions it oxidizes it into a lead powder. The rest of the system is a bag
house that leads to a HEPA filter which is exhausted to the roof area.
b. The lead comes in in blocks on vans, (I ton), then they ship out in an aluminum tanker. It is pneumatically
loaded into trucks. Usually they haul powered cement. They are filled outside, but they are covered. Under
roof.
c. Normally there is no dust. Central vacuum system under negative pressure. Unusually there is a leak, but if
there is a leak they have to stop working and clean it up. They would have to report to haz waste.
3. Q: Have you had any industrial changes since your last permit?
a. A. No. Since that time they have removed 2 production units. They now only have 213rds of the capacity.
They have been permitted to replace those 2 with 2 newer units, but there is no difference in the way they do
business.
4. Q: Did you sample for pH and if not, why? If so can you please send in the data?
a. A: They have not had the best reporting — EH&S person passed away. a will t Fo` trid me-VIeTdala

6. Q: During the shutdown period, two of the six lead oxide production units were removed; the remaining four are
currently in operation. Can you please tell me more about this?
a. A: They have removed them and they will replace them with 2 more modern ones hopefully by the end of the
year.
7. Q: Have you done anything to address the Lead benchmark exceedences? Do you think that there 's anything else you
could do to address Lead exceedences with housekeeping or storage of materials?

' The benchmark values of some metals are dependent on water hardness. For these parameters, permittees must
determine the hardness of the receiving water (see Appendix J, "Calculating Hardness in Receiving Waters for
Hardness Dependent Metals," for methodology), in accordance with Part 6.2.1.1, to identify the applicable `hardness
range' for determining their benchmark value applicable to their facility. The ranges occur in 25 mg/L increments.

Notice About Duration of Violations — The duration of violations shown on this report is an estimate of the actual
duration of the violations that might be alleged or later determined in a legal proceeding. For example, the start
date of the violation as shown in the ECHO database is normally when the government first became aware of the
violation, not the first date that the violation occurred, and the facility may have corrected the violation before the
end date shown. In some situations, violations may have been corrected by the facility, but EPA or the State has
not verified the correction of these violations. In other situations, EPA does not remove the violation flag until an
enforcement action has been resolved.

Yadkin
Pee Dee
River Basin Plan
Summary
Hydrologic Unit Code 030401
GENERAL DESCRIPTION
The Yadkin -Pee Dee River basin is the second largest basin in North
Carolina and covers approximately 7,213 square miles, spanning 21
counties. Originating on the eastern slopes of the Blue Ridge Mountains
in Caldwell and Wilkes counties, the Yadkin River flows northeasterly for
about 100 miles and then turns southeast until joined by the Uwharrie
River to form the Pee Dee River. The Pee Dee River continues its southeast
course through North and South Carolina to Winyah Bay at the Atlantic
Ocean.
Increasing nutrient enrichment, urbanization, and wastewater are the
primary impacts to water quality in this basin. Most of these impacts are
focused in the counties of Forsyth, Rowan, Iredeli, Cabarrus, Davidson,
and Union. Land conversion from forest and agricultural practices to
suburban uses is occurring nearly everywhere throughout this basin. Only
protected natural areas and steep mountainous terrain are not impacted
by these changes.
Despite these areas of concern, there are still streams in largely forested
and comparatively undeveloped catchments with very good water quality.
Most of these waters are found in northern Wilkes, western Surry, and
portions of Montgomery County (Uwharrie National Forest). In fact, of the
51 streams and rivers classified Outstanding Resource Waters (ORW) in the
Yadkin -Pee Dee River basin, 73% are located in these counties.
The Yadkin -Pee Dee River basin experienced moderate to severe drought
conditions in 2001, which had the potential to reduce the impacts from
nonpoint sources and magnify the impacts from point source discharges.
CURRENT STATUS
There are 94 impaired assessment units in the Yadkin Pee -Dee River
(Figure ,1 /Table 1). Impaired waterbodies are those streams/lakes
not meeting their associated water quality standards in more than 10
percent of the samples taken within the assessment period (January 1,
2002 through December 31, 2006) or those not meeting the narrative
standards for either benthic macroinvertebrate community criteria or fish
community criteria. Most of the stream impairments (26%) are based on
poor biological integrity measured by aquatic macroinvertebrates and
fish communities, followed by turbidity violations (19%), low dissolved
oxygen levels (6%) and elevated fecal coliform bacteria (4%). in lakes and
reservoirs, chlorophyll a exceeds the standards in 36% of the total acres
sampled, followed closely by high pH levels (35%) and turbidity in 17% of
the samples.

BIOLOGICAL SAMPLING
The basinwide biological (fish and benthic community) sampling effort in the Yadkin -
Pee Dee River basin increased by 12 percent between samples collected in 2001
and samples collected in 2006; however, this increased effort did not significantly
impact the ratio of supporting and impaired streams. Nineteen percent of the waters
sampled between 2001 and 2006 showed an improvement in biological communities
(Figure 2). There was a 17 percent decline in benthic and fish populations between
2001 and 2006. Most declines were noted in areas along the urbanizing 1-85 and 1-40
corridors, particularly in western Cabarrus County.
AMBIENT SAMPLING
Problem areas were scattered throughout the basin. See 8-digit hydrologic unit code
(HUC) subbasin sections to get specifics on individual streams and lakes.

The majority of North Carolina, including the Yadkin -Pee Dee River basin, experienced drought in 2002, and significant
rains in 2003. These dramatic changes in flow appear to account for fluctuations for many parameters, including
temperature, specific conductance, dissolved oxygen, pH, turbidity, and fecal coliform. Comparisons of the six
hydrologic units (HU) within the Yadkin -Pee Dee River basin yielded the following:
-Physical Parameters: all HUs:
• Temperature: The majority of variation in temperature is caused by seasonal and daily variation in solar
radiation and air temperature. A slight increase in surface water temperature was detected in the South Yadkin
HU. There were no discernible trends in the other five HUs.
• Specific Conductance: Conductance peaked in 2002 during the drought. Similarly it reached its lowest point
during 2003 and the end of the drought. Downward trends in conductivity values in the Yadkin River Headwaters,
the Rocky River, and the Pee Dee River reflect the end of the drought and resultant dilution due to increased
runoff and rainfall.
• Dissolved Oxygen: Dissolved Oxygen was at its lowest during the 2002 drought. Increasing concentrations in
the Yadkin River Headwaters, the Rocky River, and the Pee Dee River reflect the end of the drought.
• pH: The ending of the drought in 2003 caused a steep decline in pH values throughout the basin.
• Turbidity concentrations appear to be decreasing in the South Yadkin and High Rock Lake HUs and increasing
in the Rocky River HU. Turbidity concentrations were low during the 2002 drought, rose in 2003, and have since
stayed relatively even.
• Fecal Coliform bacteria levels peaked during the 2003 rains, and has decreased since then. Significant
downward trends are present in the Yadkin River Headwaters, the South Yadkin River, the High Rock Lake, and
the Lake Tillery HUs.
Nutrients -in Yadkin River Headwaters R South Yadkin River 8-digit HUs:
• Ammonia concentrations appeared to decrease slightly and do not appear to be related to the drought.
• Total Kjeldahl Nitrogen concentrations appeared to be decreasing and do not appear to be related to the
drought.
• Total Nitrate and Nitrite concentrations peaked during the drought and were beginning to decrease after the
drought ended.
• Total Phosphorus concentrations appeared to decrease. Concentrations were slightly higher during the
drought.
• Nutrients in Lake Tillery HU: Total Nitrate and Nitrite concentrations appeared to increase slightly.
• Nutrients in Rocky River HU: Total Phosphorus concentrations tended to be higher than in the rest of the HUs.

SIGNIFICANT ISSUES
WATER QUALITY STRESSORS Et SOURCES
Rivers and Streams
Stressors are indicators or parameters that may cause water quality degradation. Twenty-six percent of stream
impairments are based on poor biological integrity measured by aquatic macroinvertebrates and fish communities,
turbidity violations account for 19 percent, low dissolved oxygen levels six percent and elevated fecal coliform bacteria
four percent. Stream miles impaired by these parameters are indicated in Figure 3.

When evaluating water quality stressors, DWQ evaluates and identifies the source of the stressor as specifically as
possible depending on the amount of information available for that particular watershed. Sources are most often
associated with the predominant land use where the altered hydrology is able to easily deliver the water quality
stressor to the waterbody. Factors that contribute to habitat degradation include increased impervious surfaces,
sedimentation and erosion from construction, general agriculture, and other land disturbing activities. Sources
identified as contributing to water quality degradation in the Yadkin- Pee Dee River basin are found in Figure 4.

Lakes and Reservoirs
For lakes and reservoirs in the Yadkin -Pee
Dee River basin, nutrient overenrichment
is the largest stressor as evidenced by
the high percentage of waters impacted
by high chlorophyll a levels and high pH
(Figure 5). Turbidity and temperature
were the next most common stressors
to these lake and reservoir systems.
Stormwater is the predominant stressor
source for takes and reservoirs in the
Yadkin- Pee Dee River basin (Figure 6).
Stormwater is the flow of water that
results from. precipitation and usually
occurs immediately following a rainfall.
Common stormwater pollutants include
sediment, nutrients, organic matter,
bacteria, oil and grease, and toxic
substances (i.e., metals, pesticides,
herbicides, hydrocarbons). Stormwater
can also impact the temperature of a surface waterbody, which can affect the water's ability to support healthy
aquatic communities.
FIGURE 5. LAKE IMPAIRED PARAMETERS
FIGURE 6. IDENTIFIED SOURCES CONTRIBUTING TO WATER QUALITY DEGRADATION IN LAKES
Nutrients
Nutrients are significantly impacting lakes throughout the basin as evidenced by algal productivity. Most impoundments
in the piedmont are sensitive to nutrient inputs and are unable to effectively assimilate the nutrient loads exported
from developed and agricultural areas, as well as wastewater discharges. Most of the lakes sampled by DWQ during
this assessment cycle showed evidence
of nutrient overenrichment (Table 1). TABLE 1. IMPOUNDMENTS WITH INDICATIONS OF NUTRIENT OVERENRICHMENT
Nutrient overenrichment can result
in algal blooms that deplete oxygen,
kill fish and create taste and odor
problems in drinking water. A detailed
sampling report of these Lakes and
Reservoirs is available from DWQ's

Fecal Coliform
Fecal coliform concentrations peaked
during the 2003 rains and have since
decreased. Significant decreases
are present in the Yadkin River
headwaters, South Yadkin River, High
Rock Lake, and Lake Tillery HUs.
Concentrations appear to be increasing
in the Rocky River HU. While fecal
coliform concentrations appear to be
decreasing in many HUs, many samples
in all HUs were well above the 400
colonies/ml maximum limit.
Turbidity
The distribution of turbidity violations
and sample locations make it difficult
to isolate a single source of erosion
in the Yadkin River headwaters. It
appears, however, violations are
highest in the Yadkin River mainstem,
agricultural areas, and transitional
suburban areas. Violations are lowest
in the upper watershed where land
use is predominantly forest. This
observation exemplifies the utility of
stream buffers and natural areas.
Figure 7 depicts the distribution of
fecal coliform and turbidity standards
violations within the Yadkin -Pee
Dee River basin. For the most
part, elevated concentrations of
one are associated with elevated
concentrations of the other and are
found in some of the more
developed areas of the basin.
Figure 8 shows the percent of
samples per year that exceeded
50 NTUs for all ambient stations
in the entire Yadkin- Pee Dee
Basin between 1997-2007.
High rainfall events in 2003
clearly result in increased
turbidity impairments.
See: Yadkin Ambient
Monitoring System Report and
Yadkin Basinwide Assessments
for detailed sample results and
discussion.

HIGH QUALITY WATERSHEDS AT A CROSSROADS
Stream degradation in this river basin closely follows population density and land use patterns. Degradation is more
common in agriculture areas than in forested headwaters and most concentrated in urban areas. However, this
pattern may be changing as new development pressure, in the form of secluded resort communities and low -density
second home developments, increases in the forested headwaters. Many of these developments are sited in designated
High Quality and Outstanding Resource Watersheds (HQW10RW).
One of the largest residential/resort communities in North Carolina is currently under construction in the Elk Creek
ORW. Because ORW watersheds usually occur in historically rural and undisturbed areas, the long-term ability of the
management strategies to maintain ORW status in the face of these new developments remains untested.
Research suggests that streams begin to degrade when watershed imperviousness reaches ten percent of the total land
area. The ORW management strategy, however, allows for much higher densities provided the development treats the
first inch of rainfall. The management strategy also requires enhanced sediment and erosion control and, in some
cases, a 30-foot stream buffer. The management strategy does not restrict the number of developments or homes
that may be constructed in a watershed. It is unclear if these restrictions are sufficient to maintain excellent water
quality as development and cumulative imperviousness increases. New research that accurately projects development
scenarios and their impact on water quality is needed in the short term.
INTERSECTING WATER OUALITY WITH WATER QUANTITY
Recent droughts in North Carolina have raised significant concern about long term water availability for human uses.
Efforts are underway to study and update North Carolina's water supply laws and raise local water supply resistance to
future droughts. These efforts will lead to inevitable alterations in stream flow, and thus directly impact water quality.
Impacts to water quality and biological integrity must be fully examined in these planning efforts.
The Rocky River Watershed (HUC 03040105), in the southwestern portion of the basin, is one of the first regions
in North Carolina forced to find the difficult balance between clean and reliable drinking water, healthy streams,
and rapid urbanization. From Mooresville in the north to Monroe in the south, most of the suburban communities
around Charlotte depend in some way on the ecological services provided by the Rocky River and are facing strong
development pressure.
With the growing population come additional demands for drinking water supply and wastewater assimilative capacity.
Solutions for one of these will directly impact the other. For example, the stream flow volume altered by new
interbasin transfers will alter the calculations used to derive wastewater discharge permit limits. In another possible
scenario, access to additional water withdrawals by an upstream community may be restricted because downstream
discharges require a certain flow to remain in permit compliance. The complexity of this system requires close
coordination between DWQ and the Divisions of Water Resources (DWR) and Environmental Health (DEH) if a sustainable
solution is to be derived.
COORDINATING STREAM RESTORATION AND PROTECTION EFFORTS
Sixty-three waterbodies in the Yadkin -Pee Dee River basin are impaired (Appendix A) and more streams are added
during each new assessment. Population growth and associated land use changes, higher water consumption, greater
wastewater production, and stormwater runoff are major contributors to these impairments. The protection and
restoration of streams is a multi -agency effort, requiring various levels of resources and expertise. North Carolina has
shown great leadership by dedicating funding for water quality protection and restoration through several trust funds.
Additionally, a broad network of local governments, conservation trusts, and other nonprofit organizations support
stream protection and restoration at the local level. Despite these accomplishments, many water quality improvement
efforts lack adequate resources resulting in management that may be under -coordinated and inefficient.
Tighter coordination between organizations involved in restoration and protection of surface waters will lead to
expeditious and cost-effective projects. Specifically, common program goals and watersheds with the potential
to meet these goals should be identified. These watersheds should be prioritized and a concerted effort to focus
each organization's technical specialties should be undertaken. By focusing resources and spreading the burden
hetween organizations restoration projects will proceed more efficiently. DWQ has initiated an effort to bring the
state organizations together for the purpose of identifying common goals and mandates. Encouragement from DENR

management and partnerships with local organizations will go a long way towards advancing this effort and lead to new
restoration synergy.
Currently, multiple state and local agencies are actively involved in restoration efforts in Ararat River and Grants,
Coddle, Goose and Crooked Creeks' watersheds. Specific information regarding each of these efforts is detailed in its
own subbasin/watershed report. As information and resources become available these reports will be updated to
assist in coordination and tracking activities.
TOTAL MAXIMUM DAILY LOADS (TMDL)
A Total Maximum Daily Load (TMDL) is a calculation of the maximum amount of a pollutant that a waterbody can
receive and still meet water quality standards. This includes an allocation of that amount to the pollutant's sources
and a margin of safety. A TMDL includes a detailed water quality assessment that can provide the scientific foundation
for a restoration implementation plan. However, under the Federal Clean Water Act there is no requirement to
develop an implementation plan. Therefore, a TMDL by itself can only identify controls to point sources since the
allocation estimates are used for development of discharger permit limits. DWQ is supporting local development and
implementation of management strategies to address nonpoint sources in these watersheds.
TMDLs have been completed in the basin for the waters listed in Table 2. A management strategy including rules is
under development for Goose Creek. More information on Goose Creek is available at http://h2o.enr.state.nc.uslcsul
GooseCreek.html.
High Rock Lake TMDL
DWQ has initiated a TMDL development process for High Rock Lake due to violations of the turbidity and chlorophyll
a standards. Turbidity and sedimentation are significant water quality issues in the Yadkin River Headwaters. The
sediment generated in the Yadkin River Headwaters contributes directly to the water quality impairment observed in
High Rock Lake. In addition to sediment, runoff from the landscape delivers substantial nutrients to High Rock Lake
that lead to chlorophyll a violations. Residents and government agencies in the Yadkin River Headwaters are active
in the TMDL development process for the lake and will be working together to implement point and nonpoint source
pollution reduction strategies.

RIVER BASIN HYDROLOGIC UNITS
The Yadkin River basin covers over 7,000 square miles. Many management strategies a more appropriate to smaller
land areas. Therefore the basin is divided into smaller watersheds based on major drainages. Under the federal
system, the Yadkin River basin is made up of hydrologic areas referred to as cataloging units (USGS 8-digit hydrologic
units). Cataloging units ar further divided into smaller watershed units (10 and 12-digit hydrologic units or local
watersheds) that are used for smaller scale planning. Historically, DWQ has used its own 6-digit watershed numbering
system but is migrating to the federal System for consistency. A comparative map of the different systems is show in
Figure 11.

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000368
Powerlab, Inc. —Winston-Salem
Forsyth County
Dear Mr. Rabon:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
• pH monitoring has been ,added to Part II, Sec. B, Including this monitoring is a standard revision
for all stormwater permits with analytical monitoring this cycle.
• All analytical monitoring has changed to semi-annual (once in the spring and once in the falI).
This change is based on the Division's revised strategy for stormwater monitoring in renewal
permits and triakes stormwater discharge sampling frequency consistent with qualitative
monitoring. Please note that analytical monitoring must still be performed during a -
representative storm event (whereas qualitative does not).
• The Division has incorporated benchmark values into the permit. These benchmarks are not
permit limits but should -be used as guidelines for your facility's Stormwater Pollution Prevention
Plan (SPPP). If any measurements exceed benchmark values, your facility should evaluate the
effectiveness of its Best Management Practices (BMPs), review and/or update its SPPP, and
document any efforts to address Stormwater contamination (see Part II, Sections B and D).
• Total Flow monitoring has been removed. The permit still requires Total Rainfall amount and
Rainfall Event Duration be recorded for each sampling event. This change is also based on the
Divisions revised strategy for Stormwater monitoring in renewal permits. Please note that the
Stormwater Pollution Prevention Plan (SPPP) site map must include drainage area for each
outfali in acres and the percentage of each drainage area that is impervious (see Part Il, Sec. A).
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received fror--,blic or from you, this permit will likely be issued in about two months.

Permit NC5000368
Powerlab, Inc. —Winston-Salem
Forsyth County
Dear Mr. Rabon:
In response to your renewal application for continued coverage under NPDES stormwater permit NC5000368, the
Division of Water Quality (Division) is forwarding herewith the subject state - NPDES permit. This permit is
issued pursuant to the requirements of North Carolina General Statute 143-215 .1 and the Memorandum of
Agreement between North Carolina and the US Environmental Protection agency dated May 9,1994 (or as
subsequently amended).
This final permit includes no major changes from the draft permit sent to you on August 2, 2006.
Failure to complete the monitoring as required is a violation of the permit and any permit noncompliance
constitutes a violation of the Clean Water Act. Reference Part III, Section A, Item 2 "Duty to Comply", Item 9
"Penalties for Tampering" and Item 10 "Penalties for Falsification of Reports" of your permit for further
information.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to

Basis for Monitoring:
See attached monitoring data in application. Retained lead monitoring
and added pH monitoring. Activities did

All monitoring has changed to Semi -Annual (ss ng and fall). This
change is based on the Division's revised strategy for stormwater
monitoring in renewal permits and makes stormwater. discharge
sampling frequency consistent with qualitative monitoring. In
addition, DWQ has incorporated benchmark -values-into-the-permit.
These benchmarks are not permit limits but should be used as
guidelines for the facility's Stormwater Pollution Prevention Plan
(SPPP). New language in the permit specifies that if any
measurements exceed benchmark values, the facility should evaluate
the effectiveness of its BMPs, review and/or update its SPPP, and
document any efforts to address stormwater contamination (see Part
11, Sec. B & D).
Total Flow monitoring has also been removed per DWQ revised
strategy (Total Rainfall and Event Duration parameters retained).
Instead, Part II. Sec. A clarifies that SPPP site map include drainage
area for each outfall in acres and percent impervious area in each
drainage area (should flow ever need to be estimated).
Basis for Other Requirements: TMDL language included in Part II, Section B.

DOCUMENTS REVIEWED
NPDES Stormwater Permit Application Materials
S/W Permit File
Analytical &Qualitative Monitoring Results summary
Yadkin -Pee Dee Basinwide Plan (rev. March 2003)
Original EPA application (1997)
Central Office Review Summary:
Facility discharges stormwater to an unnamed tributary to Salem Creek (Middle Fork Muddy Creek), which is on
the 303(d) list of impaired waters as a result of fecal coliform Bacteria and impaired biological integrity
(unidentified stressors). The 2003 Yadkin Basinwide Plan addresses general stormwater (S/W) management
strategies for reducing urban runoff impact (from activities such as increased development and failing on -site
(domestic) wastewater systems), but does not have specific recommendations for individual industrial S/W
dischargers. Fecal coliform is likely not a pollutant of concern at this site. This watershed has been identified by
the Ecosystem Enhancement Program (EEP, formerly NC Wetlands Restoration Program) as an area with the
greatest need and opportunity for stream and wetland restoration efforts.
Since last renewal, the company has added two more production lines, more storage silos, and an addition to the
building. At renewal, the site was in the process of adding a fifth and sixth production system. The process, raw
materials, and storage practices have remained the same.
Permit file documents (November 1999 Memo from WSRO and 1999 staff report comments) indicated that all
manufacturing and storage is under roof at this facility but that the loading dock area may drain to surface waters.
The EPA Multi -Sector permit includes monitoring and benchmarks for total recoverable aluminum and iron for the
industrial inorganic chemicals industry; however, these metals are not pollutants of concern at this facility.
Qualitative Monitoring Results: Permittee sent results from 2000-04. Overall few problems; however, in late
2003-04, decrease in clarity and increase in solids observed_ May have coincided with some of the construction for
the building addition (?).
Analytical Monitoring: See analytical monitoring summary in application —only two samples for each outfall.
No monitoring during first and second quarters of Year 4? (Not submitted and no DMRs in Central Files).
Retained lead (Pb) monitoring because levels exceeded 0.0338 mg/1 benchmark at both outfalls in 2003. Reviewer
recommends adding pH monitoring because it can be important to -interpreting toxicity of contaminants (including
some metals). This change is standard for all stormwater permit renewals with analytical monitoring this cycle.
Monitoring frequency will increase to semi-annually. This change ensures at least nine data points are collected
through the permit term and makes monitoring frequency consistent with qualitative monitoring. Also, benchmark
values for all parameters have also been added to the permit as a guide for the permittee to check the effectiveness
of BMPs (and document efforts) when necessary. The lead benchmark is based on V2 FAV (final acute value) and
was derived from EPA's November 2002 Recommended Water Quality Criteria (assumed 50 mg/1 hardness).
No follow-up with the company contact was necessary.
Recommendation: Based on the documents reviewed, the application information submitted on November4, 2004
is sufficient to issue an Individual Stormwater Pe it.

Summary of Best Management Practices
Good Housekeeping
Powerlab practices good housekeeping measures to maintain a clean and orderly work
environment. A plant meeting is conducted every month in which good housekeeping
practices are discussed. At Powerlab, every employee has a job description, which
defines the activities he has to perform. Good housekeeping is a part of every
employee's job description and is practiced daily.
Operation and Maintenance - These practices ensure that processes and equipment are
working well.
• Conduct operations indoors so the potential for any oil drips and/or fuel oil leaks to
enter the storm water system have been minimized;
• Routine vehicle maintenance is performed off site by trained automotive technicians;
+ Maintain clean and dry floors by using brooms, shovels, vacuum cleaners, and
cleaning machines;
• Regular pickup and disposal of garbage and recycled material;
• Make sure equipment (especially the pressurized conduit system) is working
properly;
• Routinely inspect for leaks or conditions that could lead to discharges of chemicals;
• Routinely inspect for contact of storm water with raw materials or finished products;
• Ensure that employees understand spill cleanup procedures.
Material Storage Practices - Improper storage can result in the release of materials or
chemicals that can cause storm water runoff pollution. Proper storage techniques
implemented at Powerlab's facility include:
• Providing adequate space to facilitate material transfer and easy access for
inspections;
Page 1 of 4

f
• Storing containers, drums, and bags away from direct traffic routes to prevent
accidental spills;
• Stacking containers according to manufacturers' instructions to avoid damaging the
containers;
• Storing containers indoors on pallets or similar devices to prevent corrosion of the
containers, which can result when containers come in contact with moisture on the
ground;
• Assigning the responsibility of hazardous materials inventory to a limited number of
people who are trained to handle hazardous materials.
Material Inventory Procedures - The Powerlab facility maintains an active list of all
chemical substances authorized/on-hand for the facility/workplace. Material Safety Data
Sheets (MSDS) for each chemical substance are also stored onsite and available for
employees. Some additional procedures implemented include:
• Label all containers to show the name and type of substance, stock number,
expiration date, health hazards, suggestions for handling, and first aid information;
• Clearly mark all hazardous materials that require special handling, storage, use, and
disposal considerations.
Employee Participation - Frequent and proper training of employees in good
housekeeping techniques reduces the possibility that the chemicals or equipment will be
mishandled. Motivating employees to reduce waste generation is another important
pollution prevention technique. Some methods employed for involving employees in
good housekeeping practices:
• Employees must keep themselves and their uniforms as free of dust as possible. They
are not to walk outside the plant with dirty plant shoes, as this could contaminate the
ground. Employees must vacuum the dust from their person and uniform before
entering the locker room and whenever necessary.
• Employees must shower before they leave the plant and place dirty clothes and safety
equipment in assigned dirty lockers at the plant.
• Incorporate information sessions on good housekeeping practices into the facility's
employee training program;
• Discuss good housekeeping at employee meetings.

t
Preventive Maintenance
Preventive maintenance measures are conducted on equipment to decrease the occurrence
of mobile and stationary equipment spills. A list of measures implemented at the
Powerlab facility are identified below:
• Qualified maintenance personnel or machine operators, who evaluate the adequacy of
the equipment and make recommendations for repairs and improvements, conduct
preventative maintenance on equipment. Inspections of drums, pumps, and fittings
are conducted on a regular basis to identify leaks or defects, that might lead to a spill.
• Adjustments, repairs, or replacements of equipment are conducted as needed.
• Parking lots are inspected on a regular basis to detect spills or potential spill sources.
• The Facility Maintenance Supervisor maintains complete records on inspections,
equipment, and systems. These records are kept with other visual inspection records.
• Powerlab maintains a well -lighted site with a secure fence around the perimeter in
order to keep unauthorized personnel out.
Inspections
Routine inspections are conducted of the finished and unfinished product storage area,
chemical storage area, loading/unloading area, waste management areas, equipment
storage area, and maintenance areas.
Spill Prevention and Response
Spill prevention is a major goal of Powerlab. To avoid possible accidental spills,
equipment is placed inside a covered building. The only possibility of spill is of an oil
spill from the trucks or material spill while loading or unloading.
Trucks are loaded or unloaded only when parked on a concrete driveway so that no
chemical percolates in the soil if spilled. Spill response equipment, is kept ready for use
at all times. Employees have been educated about spill cleaning methods in the routine
plant meetings.
The only materials loaded on trucks are dross and other lead -contaminated materials,
which are kept in labeled drums totally enclosed from all sides, and lead oxide, which is
mechanically conveyed to a totally enclosed truck.
Lead is the only material unloaded. It is not a hazard to the storm water runoff even if
spilled, because it is in solid metal form. All chemicals received at Powerlab are in
manufacturers' packing, which is usually in airtight containers.
Page 3 of 4

Sediment and Erosion Control
All areas exposed to storm water are either paved, or have grass/shrubs growing.
Additionally, there are no significant changes in elevation throughout the site to cause
storm water velocity problems.

Changes in Industrial Activities
The Powerlab Winston-Salem Plant was built with two lead oxide production systems. A
third production system was added in 2000 along with a Hammer mill system to grind
part of the production and an additional storage silos. A fourth production system was
added in 2002. During the spring and summer of 2004 an addition was added to the
building and we are in the process of installing a fifth and sixth production system and
additional Hammer Mill System. Storage silos will be increased by two.
We have not changed our process or raw materials. Our storage practices remain the
same.

APPENDIX K
Feasibility Study by Management
A through feasibility study has been preformed by management to review all the operations
of the facility as to the technical and economic methods of operations or storage practices to
eliminate or reduce exposure of materials and processes to stormwater.
This study revealed that we could eliminate the single greatest potential for lead
contamination to stormwater on the site. This was in the truck loading and unloading area.
This covered area had a discharge for the rain water that blew under the covered canopy
where the trucks were loaded and unloaded. This stormwater could be contaminated if a spill
occurred while loading a tank truck. The old outfall in the truck receiving area (Outfall #3 in
old S WPPP) is now sealed off, any water that is collected at this location is pumped to the
reactor process water holding tank to help provide cooling water for the reactor units. This
water is fed to the reactor units via the air inlet pipe and is evaporated and passes out with the
process air to atmosphere as steam. Thus there is no longer a discharge from this area as
storm water and it saves the plant on purchasing water for cooling.
All processing, storage of materials and maintenance operations are carried out inside the
main plant building which does not have any discharge to stormwater. The only other areas
that are drained to the stormwater outfalls are the roof of the building and employee parking
areas.

Dear Mr. Rabon:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
• pH monitoring has been added to Part 11, Sec. B. including this monitoring is a standard revision
for all stormwater permits with analytical monitoring this cycle.
• All analytical monitoring has changed to semi-annual (once in the spring and once in the fall).
This change is based on the Division's revised strategy for stormwater monitoring in renewal
permits and makes stormwater discharge sampling frequency consistent with qualitative
monitoring. Please note that analytical monitoring must still be performed during a
representative storm event (whereas qualitative does not).
• The Division has incorporated benchmark values into the permit. These benchmarks are not
permit limits but should be used as guidelines for your facility's Stormwater Pollution Prevention
Plan (SPPP). If any measurements exceed benchmark values, your facility should evaluate the
effectiveness of its Best Management Practices (BMPs), review and/or update its SPPP, and
document any efforts to address stormwater contamination (see Part II, Sections B and D).
• Total Flow monitoring has been removed. The permit still requires Total Rainfall amount and
Rainfall Event Duration be recorded for. each sampling event. This change is also based on the
Division's revised strategy for stormwater monitoring in renewal permits. Please note that the
Stormwater Pollution Prevention Plan (SPPP) site map must include drainage area for each
outfall in acres and the percentage of each drainage area that is impervious (see Part II, Sec. A).
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about'two months.

a. Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan,shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
b. Secondary Containment Schedule. A schedu— ro`vide secondary containment
."
for bulk storage of liquid materials storageof Section 313 of Title III of the
Superfund Amendments and Reauthorization' kct (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. If the.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORNIWATER POLLUTION PREVENTION PLAN
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E. Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation
routes and surface waters, the name of the receiving water(s) to which the
stormwater outfall(s) discharges, or if the discharge is to a municipal separate
storm sewer system, the name of the municipality and the ultimate receiving
waters, and accurate latitude and longitude of the point(s) of discharge. 4
(b) A narrative description of storage practices, loading and unloading activities.
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(c) A site map drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials. disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area, building locations, existing
BMPs and impervious surfaces, and the percentage of each drainage area that is
impervious_ For each outfall, a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts-
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph 3.
2_ Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
Part 11 Page 1 of 6

•
0 Permit No. NCS000368
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by the material stored within the containment area. Records
documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a
period of five years.
(c) BMP Summary. A narrative description shall. be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan may be a component of the SPRP, but may
not be sufficient to completely address the stormwater aspects of the SPRP. The common
elements of the SPCC with the SPRP may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
Part 11 Page 2 of 6

•
• Permit No. NCS000368
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components -of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made. y
8. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once in the
spring (April -.Tune). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control

MEMORANUUM
TO: Aisha Lau
FROM: Steve Mauney "
SUBJECT: Powerlab, Inc.
NC50003b8
Forsyth County
The writer and Melissa Rosebrock inspected the site on November 18. 1999. The facility
takes lead ingots and melts it to produce a powder that will be used in battery production. The
lead ingots {bars) are unloaded from trucks or occasionally from rail cars to inside storage of all
ingots. The second loading dock is used for loading the lead powder into bulk hopper tankers for
transport to battery manufacturers. The delivery hoses (8" to 12" diameter) are connected to the
top of the hopper tankers for loading of the powder. There was no evidence of powder being lost
to the environment. However, the loading dock area may drain to surface waters and it will be
beneficial to review their sampling data.
A tour of the lab area revealed that all water (5 gallons/day) is collected, treated and put
back into the lead vat for cooking it below 700' F. All cleaning of the facility is by a central
vacuum system, so that lead dust does not become airborne by sweeping. The product storage
vats are under negative pressure to prevent loss of lead dust.
It is recommended that the permit be issued.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E. Paragraph 3 of this individual permit_ The Plan shall include, at a
minimum, the following items:
I. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation
routes and surface waters, the name of the receiving water(s) to which the
stormwater outfall(s) discharges, or if the discharge is to a municipal separate
storm sewer system, the name of the municipality and the ultimate receiving
waters; and accurate latitude and longitude of the point(s) of discharge.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(c) A site trap drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area, building locations, existing
BMPs and impervious surfaces. and the percentage of each drainage area that is
impervious. For each outfall, a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph 3.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
Part II Page 1 of 6

Permit No. NCS000368
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Super -fund Amendments -and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent Ieaks and spills from
contaminating stormwater runoff. If the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of.the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by the material stored within the containment area. Records
documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a
period of five years.
(c) BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the -_
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The-SPRP must be site
stormwater specific. Therefore, a SPCC plan may be a component of the SPRP, but may'' - s
not be sufficient to completely address the stormwater aspects of the SPRP. The common
elements of the SPCC with the SPRP may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities-' f stormwater control systems, plant equipment s
Part II Page 2 of 6

0 Permit No. NCS000368
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
5. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. PIan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part M. Standard Conditions, Section B, Paragraph 3) to the Director that the chancres
have been made.
S. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once in the
spring (April -June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be
incorporated into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part II of this permit shall
be performed in addition to facility inspections.
9. Implementation. The permittee shall document all monitoring, measurements,
inspections and maintenance activities and training provided to employees, including the
log of the sampling data and of activities taken to implement BMPs associated with the
industrial activities, including vehicle maintenance activities. Such documentation shall
be kept on -site for a period of five years and made available to the Director or his

The writer and Melissa Rosebrock inspected the site on November 18, 1999. The facility
takes -lead-irigots-and meIts_it to_ producca_powder that-will-be-used-in-battery=productio T1 e
lead ingots (bars) are unloaded from trucks or occasionally from rail cars to inside storage of all
ingots. The second loading dock is used for loading the lead powder into bulkjhopper tankers for
transport to battery manufacturers. The delivery hoses (8" to 12" diameter) are connected to the
top of the hopper tankers for loading of the powder. There was no evidence of powder being lost
to the environment. However, the loading dock area may drain to surface waters and it will be
beneficial to review their sampling data.
A tour of the lab area revealed that all water (5 gallons/day) is collected, treated and put
back into the lead vat for cooking it below 700' F. All cleaning of the facility is by a central
vacuum system, so that lead dust does not become airborne by sweeping. The product storage
vats are under negative pressure to prevent loss of lead dust.
It is recommended that the permit be issued.

This subbasin is located entirely within the piedmont
portion of the state. Muddy Creek is the largest tributary
of the Yadkin River within this subbasin and its watershed
drains the Winston-Salem area. Grants Creek, in the
southwestern part of the subbasin, flows through Salisbury,
Spencer and East Spencer. Dutchman Creek (subbasin 03-
07-05) and the South Yadkin River (subbasin 03-07-06)
enter the Yadkin River above High Rock Lake in this
subbasin. Abbotts Creek (discussed in subbasin 03-07-07)
is a tributary to High Rock Lake. The subbasin contains
all or part of more than 15 different municipalities and five
counties. The Yadkin River and High Rock Lake serve as
the county boundary between Davie and Davidson and
Rowan and Davidson counties.
A map including the locations of NPDES discharges and
water quality monitoring stations is presented in Figure 13-
4. Table B-7 contains a summary of monitoring data
types, locations and results. Use support ratings for waters in this subbasin are summarized in
Table B-8. Appendix I provides a key to discharge identification numbers. Refer to Appendix
III for a complete listing of monitored waters and more information about use support ratings.
This subbasin is one of only a few in which more than 5 percent of land is described as urban.
The northern portion of the subbasin includes Winston-Salem, Rural Hall, Tobaccoville and parts
of King, Lewisville, Clemmons and Kernersville and is almost completely developed.
Approximately 56 percent of the land is forested and nearly 35 percent is in agriculture. More
than 3 percent is surface water reflecting a large portion of the 15,750-acre High Rock Lake.
This subbasin contains more than one quarter (27 percent) of the total basin population, and the
population density in 1990 was the highest of any other subbasin. Population is expected to
increase 32 percent in Rowan, 26 percent in Forsyth and 25 percent in Davidson counties
between 2000 and 2020, The subbasin contains 40 NPDES permitted discharges and eight
registered animal operations. Facilities with compliance or toxicity problems are discussed in
following sections.
The majority of waters within this subbasin exhibit some level of impacts to water quality. Many
streams are Impaired by a combination of nonpoint and point source pollution. There are no
High Quality Waters or Outstanding Resource Waters within the subbasin.

Total stream mileslacres assigned to each use support category in this subbasin. Column is not additive because some stream
miles are assigned to more than one category.
These waters are impaired based on fish consumption advice issued for three species of freshwater fish due to mercury
contamination. Refer to page 104 of Section A for details.
4.2 Status and Recommendations for Previously Impaired Waters
This section reviews use support and recommendations detailed in the 1998 basinwide plan,
reports status of progress, gives recommendations for the next five-year cycle, and outlines
current projects aimed at improving water quality for each water. The 1998 Yadkin -Pee Dee
River basin plan identified portions of Reynolds Creek, Salem Creek and Grants Creek as
Impaired. These waters are discussed in further detail below.
4.2.1 Reynolds Creek (3.3 miles from source to Muddy Creek)
1998 Recommendations
Biological surveys conducted in 1994 revealed that Reynolds Creek was Impaired downstream of
the Sequoia WyVTP. This facility was a package WWTP serving a residential community.
DWQ recommended that an engineering alternatives analysis be conducted to determine the
feasibility of eliminating this discharge and connecting to the Winston-Salem/Forsyth County
collection system. Recommendations were also made for reducing nonpoint source pollution.
Current Status
Benthic macroin vertebrate communities in Reynolds Creek were sampled again at two locations
in 2000. Due to reduced flow, the stream was too small for bioclassifications to be assigned.
Upstream of the discharge, DWQ biologists found that there had been a slight decline over the .
six -year period, which is likely due to increased development in Lewisville. Downstream,
significant problems still existed that were attributed primarily to the WWTP. Areas of sludge
deposition were observed that were contributing to water quality problems. The Sequoia WWTP
discharge was removed in July 2001.
2002 Recommendations
Although Reynolds Creek is currently Not Rated due to its small size, significant water quality
problems still exist. DWQ will continue to monitor this stream to evaluate any improvement
Section $: Chapter 4 - Yadkin -Pee Dee River Subbasin 03-07-04 150

following the removal of the Sequioa WWTP discharge. However, local actions are needed to
reduce the effects of nonpoint source pollution, particularly from stormwater runoff, and to
restore habitat in the lower portion of the watershed. It is likely that Forsyth County and
Lewisville will be required by DWQ to obtain an NPDES permit for municipal stormwater
systems under the federal Phase II stormwater rules.
4.2.2 Salem Creek (12.0 miles from dam at Salem Lake to Muddy Creek)
1998 Recommendations
Recommendations for the Salem Creek watershed include support for the City of Winston-
Salem's stormwater program and call for further action by the city and Forsyth County to help
maintain and improve water quality in the face of continuing development. DWQ planned to
reevaluate the computer model used to determine the wasteload allocation for the Archie Elledge
WWTP and adjust the NPDES permit accordingly, based on the outcome.
Current Status
The Salem Creek watershed continues to develop, particularly in the headwaters near
Kernersville, but also on the lower end. Some habitat degradation was observed above Salem
Lake, but the majority of water quality problems exist below the confluence with Brushy Fork.
Biological surveys were conducted by DWQ at three sites below Salem Lake, and water
chemistry samples were also collected at three sites. Although a small percentage of samples
downstream of the Archie Elledge WWTP contained dissolved oxygen concentrations less than
5.0 mg/l, the WWTP does not seem to be adversely impacting the stream. Benthic
macroinvertebrate communities were very similar above and below the WWTP. Significant
habitat degradation was observed throughout the lower watershed, including severe bank erosion,
a lack of riparian vegetation, and sedimentation leading to a very uniform sand/silt substate (i.e.,
lack of pool and riffle habitat). Additionally, the fish community site, which received a Poor
bioclassification, is located upstream of the WWTP discharge. Salem Creek, from the dam at
Salem Lake to the confluence with Muddy Creek, remains Impaired.
The geometric means of fecal coliform samples collected from three stations between 1998 and
2001 and one station between 1996 and 2001 from Salem Creek (307, 327, 368 and 773
colonies/100m1) indicate that the stream may not be suitable for primary recreation. In addition,
fecal coliform concentrations were greater than 400 colonies/100ml in more than 20 percent of
samples from each site. Salem Creek is not currently classified for primary recreation (Class B).
However, the stream was historically placed on the 303(d) list for fecal coliform and a TMDL is
being developed by DWQ.
2002 Recommendations
Further investigation into the causes and sources of biological impacts to Salem Creek is needed
before specific recommendations to improve water quality can be made. Local actions are
needed to reduce sedimentation, turbidity and fecal coliform contamination and to promote the
production of instream habitat by restoring riparian vegetation throughout the watershed. DWQ
will develop a TMDL for fecal coliform and work with local agencies to implement it over the
next five-year basinwide planning cycle. Many of the BMPs employed to reduce fecal coliform
contamination will likely help reduce habitat degradation in the watershed also. In addition,
Forsyth County and Kernersville are required to obtain NPDES permits for municipal
Section B: Chapter 4 - Yadkin -Pee Dee River Subbasin 03-07-04 151

stormwater systems under the Phase 1I stormwater rules. Refer to page 37 of Section A, Chapter
2 for details.
Water Quality Improvement Projects
The Salem Creek watershed, including Peters Creek and Brushy Fork (03040101 170060), is one
of 55 watersheds in the Yadkin -Pee Dee River basin that has been identified by the NC Wetlands
Restoration Program (NCWRP) as an area with the greatest need and opportunity for stream and
wetland restoration efforts. This watershed will be given higher priority than a nontargeted
watershed for the implementation of NCWRP restoration projects. Refer to page 278 in Section
C for details.
4.2.3 Grants Creek (1.2 miles from SR 1910 to Yadkin River)
1998 Recommendations
The 1998 basin plan discussed water quality impacts from the Salisbury Grants Creek WWTP
and Spencer Sowers Ferry Road WWTP discharges and Salisbury's plans to relocate the Grants
Creek WWTP discharge to the Yadkin River. Recommendations were for DWQ to monitor the
stream following the removal of this discharge and for local action to reduce nonpoint source
pollution.
Current Status
Biological data were collected from two sites, and water chemistry data were collected from
three sites along Grants Creek over the previous basinwide planning cycle. Although the
uppermost site (above the WWTP discharges) received a Good -Fair bioclassification, biological
surveys indicated severe habitat degradation as well as nutrient enrichment. Further downstream,
Grants Creek is impaired by a combination of historical point source problems and current
nonpoint source problems.
At two water chemistry sites (above and below the WWTPs), turbidity concentrations were in
excess of state standards in more than 10 percent of samples. The geometric means of fecal
coliform samples collected from two stations between 1998 and 2001 and one station between
1996 and 2001 from Grants Creek (282, 231 and 291 colonies1100ml) indicate that the stream
may not be suitable for primary recreation. In addition, fecal coliform concentrations were
greater than 400 colonies1100m1 in more than 20 percent of samples from each site. Grants
Creek is not currently classified for primary recreation (Class B). However, the stream was
historically placed on the 303(d) list.for fecal coliform and a TMDL has already been developed
by DWQ.
The City of Salisbury relocated the Grants Creek WWTP discharge to the Yadkin River in 1998.
The City of Spencer's Sowers Ferry Road WWTP continued to have significant and chronic
problems with BOD as well as chronic problems with dissolved oxygen and total suspended
solids over the most recent assessment period (1998-2001). However, in November 2000, the
City of Salisbury purchased the Sowers Ferry Road WWTP. Salisbury worked throughout 2001
and 2002 to divert all flows into the Grants Creek WWTP and the Sowers Ferry Road WWTP
discharge was eliminated by the end of 2002.
Section B: Chapter 4 - Yadkin -Pee Dee River Subbasin 03-07-04 152

2002 Recommendations
Although Grants Creek above the City of Salisbury is not Impaired, impacts are evident. Further
investigation into the causes and sources of biological impacts in the lower portion of Grants
Creek is needed before specific recommendations to improve water quality can be made. DWQ
expects to see some improvement below the old Sowers Ferry Road WWTP during the next
basinwide planning cycle due to Salisbury's elimination of this discharge. However, local
actions will continue to be needed throughout the watershed to reduce sedimentation and
turbidity and to promote the production of instream habitat by restoring riparian vegetation.
DWQ's fecal coliform TMDL for Grants Creek was approved by the EPA in 2002. The study
revealed that the sources of fecal coliform in the Grants Creek watershed are urban sources in the
Landis, China Grove and Salisbury areas, livestock grazing and manure application on
agricultural lands and pasturelands, and wildlife in the forested areas of the watershed. The
Coliform Routing and Allocation Program was utilized to simulate instream fecal concentrations
and to allocate the fecal coliform loads to the various sources. In order for water quality
standards for fecal coliform to be met in Grants Creek, a nonpoint source load reduction of 33-60
percent under dry weather conditions and 85-97 under wet weather conditions must be met. The
model estimates that WWTP discharges contribute an insignificant percentage of the fecal
coliform loading in the watershed. In addition, both major discharges have now been removed
from Grants Creek. Therefore, the reduction allocation focuses on the fecal coliform loading
from urban sources in the Landis, China Grove and Salisbury areas and livestock grazing and
manure application on agricultural lands.
These calculations are the first step in reducing fecal coliform concentrations in the watershed.
Many of the BMPs employed to implement the TMDL will likely help reduce habitat
degradation in the watershed as well. In addition, Landis, China Grove and Salisbury are
required to obtain an NPDES permit for municipal stormwater systems under the federal Phase I1
stormwater rules. Refer to Section A, page 37 for details.
Water Quality hnprovement Projects
The Grants Creek watershed (03040103 010010) is one of 55 watersheds in the Yadkin -Pee Dee
River basin that has been identified by the NC Wetlands Restoration Program (NCWRP) as an
area with the greatest need and opportunity for stream and wetland restoration efforts. This
watershed will be given higher priority than a nontargeted watershed for the implementation of
NCWRP restoration projects. Refer to page 278 in Section C for details.
4.3 Status and Recommendations for Newly Impaired Waters
Town Creek, a portion of Muddy Creek -and High Rock Lake are rated Impaired based on recent
DWQ monitoring (1996-2001). This section outlines the potential causes and sources of
impairment and provides recommendations for improving water quality.
Section B: Chapter 4 - Yadkin -Pee Dee River Subbasin 03-07-04 153

4.3.1 Muddy Creek (15.2 miles from Mill Creek #3 to SR 2995)
Current Statics
The headwaters of Muddy Creek flow from Stokes County, and the stream is currently the
western boundary of the City of Winston-Salem. The watershed continues to develop,
particularly in the headwaters near King, Tobaccoville and Rural Hall, but also on the lower end
where Clemmons and Winston-Salem meet. Some habitat degradation was observed above the
confluence with Mill Creek, but the majority of water quality problems exist below this point.
On the low end, the stream exhibits some recovery below the confluence with South Fork Muddy
Creek; however, impacts are evident in this portion of stream as well. The middle portion of
Muddy Creek is Impaired based primarily on fish community data collected in 1996 and 2001.
Benthic macroinvertebrate communities in this middle reach of stream have also received
bioclassifications that indicate impairment, although these communities were not sampled at this
location over the most recent assessment period.
Water chemistry is collected at three locations along Muddy Creek. Elevated nutrients, turbidity
and fecal coliform were observed over the five-year period (1996-2001). The geometric means
of fecal coliform samples collected from two stations between 1998 and 2001 and one station
between 1996 and 2001 from Muddy Creek (265, 255 and 488 colonies/100ml) indicate that the
stream may not be suitable for primary recreation. Fecal coliform concentrations were greater
than 400 colonies/100ml in more than 20 percent of samples from each site as well. Current
methodology requires additional bacteriological sampling for streams with a geometric mean
greater than 200 colonies/100m1 or when concentrations exceed 400 col/100ml in more than 20
percent of samples. However, these additional assessments are prioritized such that, as
monitoring resources become available, the highest priority is given to those streams where the
likelihood of full -body contact recreation is greatest. Muddy Creek is not currently classified for
primary recreation (Class B).
The impairment of Muddy Creek is primarily attributed to nonpoint source pollution from
stormwater runoff from construction sites and developed areas. The input of heavily developed
and/or Impaired tributaries also contributes: Mill, Silas, Reynolds and Salem Creeks.
2002 Reconunendations
Further investigation into the actual causes and sources of biological impacts to Muddy Creek is
needed before specific recommendations to improve water quality can be made; however, the
potential for water quality improvement for this stream is still strong. Local actions are needed
to reduce sedimentation, turbidity and fecal coliform contamination and to promote the
production of instream habitat by restoring riparian vegetation throughout the watershed. In
addition, Forsyth County as well as King, Tobbacoville, Rural Hall, Lewisville and Clemmons
are required by DWQ to obtain an NPDES permit for municipal stormwater systems under the
Phase II stormwater rules. Refer to SectiorrA, page 37 for details. Section A. Chapter 4 contains
more recommendations for reducing habitat degradation from stormwater runoff.
Water Quali1y /TnprOyenient ProieCts
Although Muddy Creek is not one of 55 watersheds in the Yadkin -Pee Dee River basin that has
been identified by the NC Wetlands Restoration Program (NCWRP) as an area with the greatest
need and opportunity for stream and wetland restoration efforts, several of its tributary
Section 8: Chapter 4 - Yadkin -Pee Dee River Subbasin 03-07-04 154

watersheds have been selected. The Mill Creek, Silas Creek and South Fork Muddy Creek
watersheds have been targeted. These watersheds will be given higher priority than nontargeted
watersheds for the implementation of NCWRP restoration projects. Refer to page 278 in Section
C for details.
4.3.2 Town Creek (15.4 miles from source to Crane Creek)
Current Status
Town Creek begins just east of Kannapolis and flows through Salisbury and East Spencer before
reaching High Rock Lake. The City of Salisbury historically had a discharge from a WWTP on
Town Creek. Significant improvement has been observed since the discharge was removed in
1990. However, both fish and benthic communities are Impaired in Town Creek. Habitat
degradation was noted along with a few occurrences of low dissolved oxygen and elevated
turbidity. The lower half of the watershed is heavily developed, and stormwater runoff is likely a
major contributor to the impairment. There is one minor discharge in the headwaters which
continues to be compliant with its NPDES permit.
2002 Recommendations
DWQ plans to conduct further investigation into the causes and sources of the biological
impairment of Town Creek during this basinwide planning cycle. DWQ will notify local
agencies of water quality concerns regarding these waters and work with them to conduct further
monitoring and to locate sources of water quality protection funding. In addition, Rowan County
and Salisbury are required to obtain an NPDES permit for municipal stormwater systems under
the Phase II stormwater rules. Refer to Section A, page 37 for details.
Water Quality Improvement Projects
The Town Creek watershed (03040103 010020) is one of 55 watersheds in the Yadkin -Pee Dee
River basin that has been identified by the NC Wetlands Restoration Program (NCWRP) as an
area with the greatest need and opportunity for stream and wetland restoration efforts. This
watershed will be given higher priority than a nontargeted watershed for the implementation of
NCWRP restoration projects. Refer to page 278 in Section C for details.
4.3.3 High Rock Lake (15,750 acres)
1998 Recommendations
High Rock Lake was not rated Impaired during the assessment period leading up to the 1998
Yadkin -Pee Dee River basin plan. However, the lake was rated support threatened and is
extensively discussed in the plan, indicating impacts to water quality that could lead to
impairment: The plan focuses on problems with excessive algal growths related to high nutrient
levels in the arms of the lake. Although nutrients were also high in the main body of the lake,
designated uses seemed to be supported. Recommendations are for DWQ to investigate the
feasibility of developing a nutrient strategy for the watershed and consider reclassifying the lake
as Nutrient Sensitive Waters. DWQ also planned to require phosphorus limits for major
discharges into the arms and urged all major dischargers in the watershed to identify ways to
optimize phosphorus removal using existing capabilities.
Section B: Chapter 4 - Yadkin -Pee Dee River Subbasin 03-07-04 155

Current Status
Eight stations on High Rock Lake were monitored by DWQ in 1999, 2000 and 2001. This
increased monitoring of High Rock Lake over the most recent assessment period has allowed
DWQ to determine that the lake is Impaired. The decision is based on high levels of nutrients,
combined with chlorophyll a, turbidity and percent dissolved oxygen saturation in excess of state
standards. Low dissolved oxygen and high turbidity in the Abbotts Creek and Town Creek Arms
are also contributing to aquatic life impairment. An extensive discussion of water quality data
collected from High Rock Lake is found in Section A, Chapter 4 beginning on page 107.
2002 Recommendations
The High Rock Lake watershed (map on page 279) comprises slightly more than half of the
Yadkin -Pee Dee River basin. Recommendations for improving water quality in the lake are
detailed in Section A, Chapter 4: Recommendations for Water Quality Issues Related to Multiple
Subbasins in the Yadkin -Pee Dee River Basin. The High Rock Lake part of the discussion begins
on page 107.
4.4 Section 303(d) Listed Waters
Currently, portions of six waters in this subbasin are listed on the state's draft 2002 303(d) list
for biological impairment: Reynolds Creek, Salem Creek, Grants Creek, Town Creek and two
small unnamed tributaries. Grants Creek and a portion of Salem Creek are also listed for fecal
coliform and turbidity. A fecal coliform TMDL for Grants Creek has been developed by DWQ,
and one for Salem Creek will likely be developed during this basinwide planning cycle. Refer to
Appendix IV for more information on the state's 303(d) list and listing requirements.
4.5 Status and Recommendations for Waters with Notable Impacts
Based on DWQ's most recent use support assessment, the surface waters discussed below are not
Impaired. However, notable water quality impacts were documented. While these waters are not
considered Impaired, attention and resources should be focused on them over the next basinwide
planning cycle to prevent additional degradation or facilitate water quality improvement. A
discussion of how impairment is determined can be found in Appendix III.
Although no action is required for these streams, voluntary implementation of BMPs is
encouraged and continued monitoring is recommended. DWQ will notify local agencies and
others of water quality concerns discussed below and work with them to conduct further
monitoring and to locate sources of water quality protection funding. Additionally, education on
local water quality issues is always a useful tool to prevent water quality problems and to
promote restoration efforts. Nonpoint source agency contacts are listed in Appendix VI.
4.5.1 Mill Creek
Silas Creek
Mill and Silas Creeks parallel Salem Creek in the Muddy Creek watershed. These streams are
likely being impacted by stormwater runoff from the City of Winston-Salem. Mill Creek has not
been sampled by DWQ, but the lower two-thirds of the watershed contain moderate road
Section B: Chapter 4 - Yadkin -Pee Dee River Subbasin 03-07-04 156

coverage indicating large amounts of developed area, similar to the watershed of Silas Creek.
The fish community of Silas Creek was sampled by DWQ for the first time in 2001. Severe
habitat degradation was observed and the data indicated impairment. However, the stream was
resampled in 2002 and received a Good -Fair bioclassification. This score is likely due to the
reduction in nonpoint source pollution that accompanies an extended drought. Refer to Section
A, Chapter 4 for recommendations and management strategies for reducing impacts of runoff
from developed areas.
The Mill Creek and Silas Creek watersheds (03040101 170020 and 170040) are two of 55
watersheds in the Yadkin -Pee Dee River basin that have been identified by the Wetlands
Restoration Program as areas with the greatest need and opportunity for stream and wetland
restoration efforts. These watersheds will be given higher priority than nontargeted watersheds
for the implementation of NCWRP restoration projects. Refer to page 278 in Section C for
details.
4.5.2 Salem Lake
Kerners Mill Creek
Although the most severe water quality problems in the Salem Creek watershed occur
downstream of Salem Lake, habitat degradation has been observed in Kerners Mill Creek above
the lake. In addition, this water supply lake exhibits signs of nutrient enrichment and a diverse
assemblage of algae. The Lowery Creek arm exhibits slightly lower dissolved oxygen compared
with the other two stations on Salem Lake. Local actions are needed to reduce the effects of
nonpoint source pollution in the Salem Lake watershed, particularly from stormwater runoff
from construction sites and developed areas. Kernersville is required to obtain an NPDES permit
for municipal stormwater systems under the Phase II stormwater rules. Refer to page 37 of
Section A, Chapter 2 for details.
The Salem Creek watershed (03040101 170060) is one of 55 watersheds in the Yadkin -Pee Dee
River basin that has been identified by the NC Wetlands Restoration Program (NCWRP) as an
area with the greatest need and opportunity for stream and wetland restoration efforts. This
watershed will be given higher priority than a nontargeted watershed for the implementation of
NCWRP restoration projects. Refer to page 278 in Section C for details.
4.5.3 South Fork Muddy Creek
South Fork Muddy Creek borders the City of Winston-Salem on the southeastern side. The
watershed contains a mix of residential and agricultural land uses. Most of the new development
is occurring in the Fiddlers Creek watershed. Substantial habitat degradation was observed
during biological surveys of South Fork Muddy Creek below the confluence of Fiddlers Creek.
The Good -Fair bioclassification could be due to the reduction in nonpoint source pollution that
accompanies an extended drought. Local actions are needed to reduce the effects of nonpoint
source pollution, particularly from stormwater runoff from construction sites and developed areas
in Fiddlers Creek, but also from agricultural activities in other parts of the watershed.
The South Fork Muddy Creek watershed (03040101 170070) is one of 55 watersheds in the
Yadkin -Pee Dee River basin that has been identified by the NC Wetlands Restoration Program
Section B: Chapter 4 - Yadkin -Pee Dee River Subbasin 03-07-04 157

(NCWRP) as an area with the greatest need and opportunity for stream and wetland restoration
efforts. This watershed will be given higher priority than a nontargeted watershed for the
implementation of NCWRP restoration projects. Refer to page 278 in Section C for details.
4.5.4 North Potts Creek
South Potts Creek
North and South Potts Creeks flow south in Davidson County near Lexington into the upper
reaches of High Rock Lake. The South Potts Creek watershed (larger of the two) is mostly in
agriculture, with the exception of the 1-85 corridor and a large rail yard on the lower end. Some
historic channelization is evident, and residential development is increasing along US 29/70
between Lexington and Spencer. One NPDES permitted discharge (Davidson County
Churchland Elementary) is in significant noncompliance for ammonia in the headwaters.
There is already more developed area in the North Potts Creek watershed and major
channelization has occurred. Two NPDES permitted discharges (Davidson County Tyro Junior
High and West Davidson High) are in significant noncompliance for BOD, ammonia and
chlorine. DWQ sampled North Potts Creek in 1988, but there is no recent data for either stream.
DWQ will attempt to conduct a special study of these streams during the next basinwide
planning cycle to determine: 1) the level of impacts associated with these land uses and
discharges; and 2) the contribution of this watershed to the impairment of High Rock Lake. In
addition, local actions are needed to reduce the effects of nonpoint source pollution, particularly
from stormwater runoff.
4.6 Additional Water Quality Issues with Subbasin 03-07-04
The previous parts discussed water quality concerns for specific stream segments. This section
discusses water quality issues related to multiple watersheds within the subbasin. Information
found in this section may be related to concerns about things that threaten water quality or about
plans and actions to improve water quality.
4.6.1 NPDES Discharges
Twenty-two of the 40 NPDES discharges had a few permit violations over the two-year review
period (September 1999 - August 2001). Nine facilities are in significant noncompliance; six are
Davidson County schools. Almost every school in Davidson County is in significant
noncompliance for at least one parameter. Because the facilities are scattered throughout several
subbasins, these problems and the plans to correct them are discussed on page 113 of Section A,
Chapter 4. Color/Tex Finishing had significant problems meeting COD, pH and total suspended
solids limits in 2000. The Sowers Ferry Road WWTP (originally, owned by Spencer, then
bought by Salisbury) was in significant noncompliance over the entire period of review for
problems meeting BOD, dissolved oxygen and total suspended solids limits. This discharge was
eliminated in 2002. The Hilltop Living Center had problems meeting BOD limits over the two-
year review period.
Section B_ Chapter 4 - Yadkin -Pee Dee River Subbashn 03-07-04 158

Fifteen facilities are required to monitor effluent toxicity; three have had significant compliance
problems over the previous basinwide planning cycle. The Lucent Technologies groundwater
remediation facility failed four consecutive chronic toxicity tests during the period from March
to June of 1999. Facility staff replaced the system's carbon filter media and optimized
application of treatment chemicals to address the problem. No failures have occurred since June
1999. Noncompliances in 1999 and 2000 at the City of Salisbury's Sowers Road WWTP seemed
to be associated with operational problems at the WWTP. There were no WET test failures
between September 2000 and 2002 when the discharge was eliminated. The Scarlett Acres
Mobile Home Park WWTP has produced sporadic failures since it began operation in 1990. Its
most recent noncompliances in 2001 have been attributed to poor operation and numerous power
outages.
4.6.2 Projected Population Growth
The population of Rowan County is projected to increase 32 percent, Davidson County — 25
percent, and Forsyth County — 26 percent between 2000 and 2020. Much of this development is
likely to occur along highway corridors (I-40, I-85, US 64 and US 29/70) and in smaller
suburban municipalities like King, Kernersville, Lewisville and Clemmons. Figure B-5 presents
population increases between 1990 and 2000 for selected municipalities this subbasin.

Growth management within the next five years will be imperative in order to improve or
maintain water quality in this subbasin. Growth management can be defined as the application of
strategies and practices that help achieve sustainable development in harmony with the
conservation of environmental qualities and features of an area. On a local level, growth
management often involves planning and development review requirements that are designed to
maintain or improve water quality. Refer to Section A, Chapter 4 for more information about
minimizing impacts to water quality from development.
Section B: Chapter 4 - Yadkin -Pee Dee River Subhasin 03-07-04 159

4.6.3 The South YadkinNadkin River Corridor Conservation Plan
The LandTrust for Central NC (LTCNC) received $7,500 from the Conservation Trust for North
Carolina and the Clean Water Management Trust Fund to develop a report evaluating the
conservation needs and opportunities along 24 miles of the lower South Yadkin River and a 26-
mile section of the Yadkin River above High Rock Lake. This corridor incidentally included a
portion of lower Grants Creek as well.
The South Yadkin/Yadkin River Corridor Conservation Plan was completed in December 2001.
The highest priorities for conservation identified by the plan are land between Fourth Creek and
the South Yadkin River, above and including the confluence of the two streams; and land
between the South Yadkin River and the Yadkin River, above and including the confluence of
the two rivers. There are large tracts of land (owned by Duke Power -Progress Energy) along the
Yadkin River which are in close proximity to lands that are already by LTCNC. There are also
large amounts of riparian land (owned by ALCOA) along both the South Yadkin and Yadkin
Rivers. These Duke Power and ALCOA lands also received high priority for protection (Merrill,
December 2001).
The conservation plan has been integrated into the daily efforts of LTCNC while pursuing
conservation opportunities in the Yadkin -Pee Dee River basin. Page 294 of Section C contains
more information about The LandTrust for Central NC. You may also visit the website for
details about the many lands which LTCNC helped place in conservation ownership at
