Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than O,1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred, A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

Qualitativemonitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. i

Dear Bethany:
The results of storm water sampling for the first reporting period in 2012 have been received by
SCM Metal Products. The results from the first set of samples indicated that the Total
Suspended Solids (TSS) was above the benchmark value of 100 mg/l. The value obtained at
Outfall 3 was exceedingly high and one obtained at Outfall I was slightly above the benchmark
value. Also, the copper values obtained at these two sample sites were higher than SCM's recent
historical results. Results obtained from subsequent sampling showed the TSS to be within the
benchmark value at all the outfalls and all the copper results, except one, to be within the
historical result values. The values are presented on the Stormwater Discharge Outfall (SDO)
Monitoring Report which is attached to this letter.
A few factors may have contributed to the high TSS. These include:
1. The sampling technique used at the outfalls. Rather than taking the sample at an area of
moving water, the collection bottle was placed in a relatively slow -moving portion of the
storm water stream. The collection of TSS samples has improved and will be described
in the revised Storm Water Monitoring Plan.
2. There had been an extraordinary rain event on the weekend of May 5 when more than
two and one -quarter inches fell. This amount of water may have skewed the results of
the samples taken three days later by moving a large amount of soil and other material
into the storm water streams.
3. The sampling done was the first conducted since grading and drain work was done on the
area that feeds Outfall 3. This grading work was done to control flooding in one of our
buildings and to minimize erosion. The recently install "crush and run" gravel is still
settling and this run-off may have added to the TSS result.
A few factors that may have contributed to the higher than typical copper results include:
1. The need to improve the maintenance schedule of the bio-retention device. The influent
and effluent of the device was measured; these results showed that the device had lost
effectiveness. The mulch was tested for copper content and it showed a high copper

content. A schedule will be put in place to test the mulch on a bi-monthly basis and
perform effluent testing of the bio-retention device when possible.
2. Drainage of water from a cooling water pump seal.
3. The storm water monitoring plan will be updated and re -implemented. It is expected that
areas that contribute copper and solids will be identified with the revised plan.
In accordance with the conditions of SCM's storm water permit, inspections were conducted
within two weeks of receiving the sampling results. Additionally, sampling was performed on
two subsequent measureable storm events.
One of the first actions taken after the receipt of the results was to inform all employees of the
test results at the monthly safety meetings on May 24 and 25. In addition to sharing the results,
the employees were reminded to review the storm water pollution prevention plan, renew their
diligence in maintaining BMP's and suggest additional BMP's.
On May 30, 2012, an inspection of the storm water discharge areas was performed by
Mr. James Whitacre, a Professional Engineer with Advanced Civil Design, Cary, NC and
Mr. Gerard Reverri, SCM Metal Products. On June 1, 2012 an inspection of the facility was
conducted by the SCM Storm Water Monitoring Plan sampling team. Potential source controls,
operational controls and physical improvements were identified. Actions that should bring the
TSS parameter to within the benchmark level and improve the copper level include:
1. The "floor tanks" used to store copper powder before the powder is used in SCM copper
brazing paste process have been moved from outdoor storage to indoor storage.
(Completed)
2. Replace mulch in bio-retention device. (Completed)
3. Implement a schedule to regularly measure the copper content of the mulch in the bio-
retention device. (To be done.)
4. Improve the capture of pump seal water at the cooling tower cold water well pump.
(Completed)
5. Revise the Storm Water Monitoring plan to reflect the changes in the storm water
discharge layout. (To be done.)
6. Add gravel and stabilize any area where the existing gravel has been undercut by water.
(To be done.)
7. Place a small sump in the last inlet before the drainage exits the gravel area on the east
side of the building. This sump will act as a settling area for solids. (To be done.)
8. Adding an additional inlet on the east side of the Microbond Building to intercept the
offsite water that is currently draining onto the property and causing some erosion in the
gravel. (To be done.)
9. Install a scour hole to slow down the water flow into the woods and to help capture
suspended solids before they are discharged into the existing ditch. (To be done.)
10. Install a permanent sediment riser at the end of the north swale at the existing pipe.
Currently there is fence and aggregate stopping some of the sediment but a better long
term solution would be a pipe riser wrapped in filter fabric. The filter fabric should be
cleaned and/or replaced periodically as sediment accumulates. (To be done.)

11. The 36" outfall pipe that the ditch and bio-retention area drain into will be hydro jetted
and cleaned out. After cleaning the pipe will be inspected by camera. (To be done.)
12. An investigation of plantings in the north swale will be conducted this summer and fall.
The parameter values obtained from the May 9 storm event are not the within results the
expected by SCM. It is hoped that these results are an aberration and the subsequent sample
results are indicative of the improvements that SCM has implemented. The values of the May 9
sampling have been addressed in accordance to the provisions of SCM's permit and we expect
that the actions already taken and those to be done will further improve the quality of SCM's
storm water discharge.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
i obtains approval from the local DWQ Regional Office.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement, Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

some permits do not have this requirement, Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

To Whom It May Concern:
I previously submitted a permit renewal form for SCM Metal Products, Inc., permit No. NCS000050. At
the time of the submission, SCM Metals did not have the analytical monitoring results, or visual monitoring
results for period 2 of year 5 completed. Therefore, these results for period 2 of year 5 were not included in
the prior submission.
I have since obtained these results and would like to submit the completed summary of analytical results
and visual monitoring for period 2 of year 5, as stated in permit NCS000050. I have enclosed a completed
summary of analytical monitoring results, as well as a completed summary of visual monitoring results for
the said period.
If you have any questions or require additional information, please contact me at wriscilinscmtnetals.com,
and I can also be reached direct at [phone].

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours i
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

event" or "measureable storm even t"(requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
j and that is preceded by at least 72 hours (3.days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results.inan actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply If the permittee Is' able to document that a shorter
Interval is representative for local storm events during the. sampling period, and the permittee '
obtains apEroval from the local DWQ Re ional Office.
By thi 4nature, I certify that this report Is accurate and complete to the best of my knowledge:

Dear Bethany:
The results of storm water sampling for the first reporting period in 2012 have been received by
SCM Metal Products. The results from the first set of samples indicated that the Total
Suspended'Solids (TSS) was above the benchmark value of 100 mg/l. The value obtained at
Outfall 3 was exceedingly high and one obtained at Outfall 1 was slightly above the benchmark
value. Also, the copper values obtained at these two sample sites were higher than SCM's recent
historical results. Results obtained from subsequent sampling showed the TSS to be within the
benchmark value at all the outfalls and all the copper results, except one, to be within the
historical result values. The values are presented on the Stormwater Discharge Outfall (SDO)
Monitoring Report which is attached to this letter.
A few factors may have contributed to the high TSS. These include:
I . The sampling technique used at the outfalls. Rather than taking the sample at an area of
moving water, the collection bottle was placed in a relatively slow -moving portion of the
storm water stream. The collection of TSS samples has improved and will be described
in the revised Storm Water Monitoring Plan.
2. There had been an extraordinary rain event on the weekend of May 5 when more than
two and one -quarter inches fell. This amount of water may have skewed the results of
the samples taken three days later by moving a large amount of soil and other material
into the storm water streams.
3. The sampling done was the first conducted since grading and drain work was done on the
area that feeds Outfall' 3. This grading work was done to control flooding in one of our
buildings and to minimize erosion. The recently install "crush and run" gravel is still
settling and this run-off may have added to the TSS result.
A few factors that may have contributed to the higher than typical copper results include:
1. The need to improve the maintenance schedule of the bio-retention device. The influent
and effluent of the device was measured; these results showed that the device had lost
effectiveness. The mulch was tested for copper content and it showed a high copper

content. A schedule will be put in place to test the mulch on a bi-monthly basis and
perform effluent testing of the bio-retention device when possible.
2. Drainage of water from a cooling water purnp seal.
3. The storm water monitoring plan will be updated and re -implemented. It is expected that
areas that contribute copper and solids will be identified with the revised plan.
In accordance with the conditions of SCM's storm water permit, inspections were conducted
within two weeks of receiving the sampling results. Additionally, sampling was performed on
two subsequent measureable storm events.
One of the first actions taken after the receipt of the results was to inform all employees of the
test results at the monthly safety meetings on May 24 and 25. in addition to sharing the results,
the employees were reminded to review the storm water pollution prevention plan, renew their
diligence in maintaining BMP's and suggest additional BMP's.
On May 30, 2012, an inspection of the storm water discharge areas was performed by
Mr. James Whitacre, a Professional Engineer with Advanced Civil Design, Cary, NC and
Mr. Gerard Reverri, SCM Metal Products. On June 1, 2012 an inspection of the facility was
conducted by the SCM Storm Water Monitoring Plan sampling team. Potential source controls,
operational controls and physical improvements were identified. Actions that should bring the
TSS parameter to within the benchmark level and improve the copper level include:
1. The "floor tanks" used to store copper powder before the powder is used in SCM copper
brazing paste process have been moved from outdoor storage to indoor storage.
(Completed)
2. Replace mulch in bio-retention device. (Completed)
3. Implement a schedule to regularly measure the copper content of the mulch in the bio-
retention device. (To be done.)
4. Improve the capture of pump seal water at the cooling tower cold water well pump.
(Completed)
5. Revise the Storm Water Monitoring plan to reflect the changes in the storm water
discharge layout. (To be done.)
6. Add gravel and stabilize any area where the existing gravel has been undercut by water.
(To be done.)
7. Place a small sump in the last inlet before the drainage exits the gravel area on the east
side of the building. This sump will act as a settling area for solids. (To be done.)
8. Adding an additional inlet on the east side of the Microbond Building to intercept the
offshe water that is currently draining onto the property and causing some erosion in the
gravel. (To be done.)
9. install a scour hole to slow down the water flow into the woods and to help capture
suspended solids before they are discharged into the existing ditch. (To be done.)
10. Install a permanent sediment riser at the end of the north swale at the existing pipe.
Currently there is fence and aggregate stopping some of the sediment but a better long
term solution would be a pipe riser wrapped in filter fabric. The filter fabric should be
cleaned and/or replaced periodically as sediment accumulates. (To be done.)

Ms. Bethany A. Georgoulias . July 6, 2012 Page 3 of 3
11. The 36" outfall pipe that the ditch and bio-retention area drain into will be hydro jetted
and cleaned out. After cleaning the pipe will be inspected by camera. {To be done.}
12. An investigation of plantings in the north swale will be conducted this summer and fail.
The parameter values obtained from the May 9 storm event are not the within results the
expected by SCM. It is hoped that these results are an aberration and the subsequent sample
results are indicative of the improvements that SCM has implemented. The values of the May 9
sampling have been addressed in accordance to the provisions of SCM's permit and we expect
that the actions already taken and those to be done will further improve the quality of SCM's
storm water discharge.

Attached is a letter summarizing the results of SCM's storm water testing for the first half of 2012. The initial testing
was disconcerting and the'actions we have taken and will take are described in the letter.
Even with all the rain we had this first half, it was difficult to get samples because it seemed that the rain occurred at
night or on weekends.
Please be assured that SCM is working to improve the quality of our storm water discharge. If you have any questions,
please contact me.

#4 SUMMARY OF BEST MANAGEMENT PRACTICES
1. A drum crusher is used to compact empty scrap drums for recycling. A small containment
berm and a catch basin have been added. The crusher and area are inspected on the semi-
annual site inspections.
2. A daily inspection of the outside raw material storage area and the cleaning up of any spills,
wastes, or trash is documented in a log kept by the shift foreman.
3. Planned BMP -to add broken bag detectors to our dust collectors is in progress.
4. Planned BMP - for the addition of two major dust collectors is also in -progress and will be
complete by May 1, 1999. This BMP will consist of dust collectors to capture the exhaust of
our copper melting furnace and our two copper powder reduction furnaces.
5. Planned BMP — improvements to existing dust collectors to increase efficiency.
6. Hired consultant to review all existing dust collection systems and make recommendations
for changes. Currently implementing recommended changes
#5 NARRATIVE ON SIGNIFICANT CHANGES IN INDUSTRIAL ACTIVITIES
The only significant change in industrial activities at this facility would be the change from
dissociated ammonia to hydrogen as a reducing atmosphere in our furnaces. We have
removed our outside ammonia storage tank and are operating from a temporary liquid
hydrogen tank. We are working on the installation of a permanent liquid hydrogen tank,
A new building attached to the east side of the warehouse has been added. It is designated
"Microbond" on the site drawing included. It was built to house existing production
operations plus a new solder alloy atomizing operation.
The processing of tool steel powders is no longer done at this facility.

Subbasin 03-06-05 overlies the geology of the Triassic
Basin, with all but the largest streams having regular
very low flow periods. Most of the watershed is
forested, with large urban areas in the eastern upland
areas. Jordan Reservoir is a substantial percentage of the
subbasin area. Development is occurring in the Wake
County portion of the subbasin. Population is expected
to grow by 250,000 people in counties with portions or
all of their areas in this subbasin by 2020. Most of the
growth is expected in Wake County, with only a small
portion in this subbasin.
There are 11 individual NPDES wastewater discharge
permits in this subbasin with a permitted flow of 32.4
MGD (Figure 8). The largest are Triangle WWTP (12
MGD) and South Durham WRF (20 MGD). Refer to
Appendix VI and Chapter 30 for more information on
NPDES permit holders. Issues related to compliance
with NPDES permit conditions are discussed below in
Section 5.3 for Impaired waters and in Section 5.4 for
other waters.
Apex, Cary, Durham and Morrisville are required to
develop Phase II stormwater programs (Chapter 31).
There were four benthic macroinvertebrate community
samples and one fish community sample (Figure 8 and Table 12) collected during this
assessment period. Data were also collected from six ambient monitoring stations including one
DWQ station, four UCFRBA (Appendix V) stations and one shared ambient station. Three
reservoirs were also monitored. Refer to the 2003 Cape Fear River Basinwide Assessment
Report at http://www.esb.enr.state.ne.us/bar.htmi and Appendix IV for more information on
monitoring.
Waters in the following sections are identified by assessment unit number (AU#). This number
is used to track defined segments in the water quality assessment database, 303(d) Impaired
waters list and the various tables in this basin plan. The assessment unit number is a subset of
the DWQ index number (classification identification number). A letter attached to the end of the
AU# indicates that the assessment is smaller than the DWQ index segment. No letter indicates
that the assessment unit and the DWQ index segment are the same.

5.2 Use Support Assessment Summary
Use support ratings were assigned for waters in subbasin 03-06-05 in the aquatic life, recreation,
fish consumption and water supply categories. All waters are Impaired on an evaluated basis in
the fish consumption category because fish consumption advice that applies to the entire basin.
In the water supply category, all WS classified waters (10,902.4 acres and 1249 miles) are
Supporting on an evaluated basis based on reports from DEH regional water treatment plant
consultants. Refer to Appendix X for a complete list of monitored waters and more information
on Supporting monitored waters.
There were 49.9 stream miles (25.6 percent) and 8,288.8 freshwater acres (76.0 percent)
monitored during this assessment period in the aquatic life category. There were 21.1 miles
(10.9 percent) and 8,288.8 acres (76.0 percent) of Impaired waters in this category. There were
also 3.3 miles (1.7 percent) Impaired for recreation in this subbasin.
5.3 Status and Recommendations of Previously and Newly Impaired
Waters
The following waters were either identified as Impaired in the previous basin plan (2000) or are
newly Impaired based on recent data. If previously identified as Impaired, the water will either
remain on the state's 303(d) list or will be delisted based on recent data showing water quality
improvements. If the water is newly Impaired, it will likely be placed on the 2006 303(d) list.
The current status and recommendations for addressing these waters are presented below, and
each is identified by an assessment unit number (AU#). Refer to the overview for more
information on AUs. Information regarding 303(d) listing and reporting methodology is
presented in Appendix VII.
5.3.1 B. Everett Jordan Reservoir
New Hope Creek Arm [AU # 1641-1-(14)1
New Hope River Arm [AU # 1641-(0.5) and (3.5)a]
Morgan Creek Arm [AU # 16-41-2-(9.5)]
Haw River Arm [AU # 16-(37.3) and (37.5)]
2000 Recommendations
The 2000 basin plan recommended that DWQ continue to monitor Jordan Reservoir to assess
impacts from increasing wastewater discharges and development in the watershed and to update
the NSW strategy for the reservoir and its watershed.
Current Status
Jordan Reservoir (9,766.5 acres) is Impaired because the chlorophyll a standard was violated at
stations in all mainstem segments of the reservoir and because modeling indicated violations of
the chlorophyll a standard in the New Hope Creek, Morgan Creek and Haw River Arms of the
reservoir. The highest chlorophyll a levels were collected from August to November.
Chlorophyll a levels exceeded the standard in 73 percent of samples in the New Hope River Arm
and in 13 percent of samples in mid reservoir. Blooms of blue-green algae associated with taste
and odor problems in drinking water were observed in July 2003. The reservoir has been
eutrophic since 1982. The Beaver Creek, Parkers Creek and White Oak Creek Arms (2,613.5
DRAFT Chapter 5 — Cape Fear River Subbasin 03-06-05 61

acres) are Not Rated for aquatic life. Data to assess recreation use support were not collected in
the reservoir. For more information on use support assessment and 303(d) listing refer to
Chapter 36
2005 Recommendations
Refer to Chapter 36 for complete discussions of the Jordan NSW strategy, TMDLs, modeling,
monitoring, HB515 and S131366. DWQ, with the Jordan stakeholders, will continue to monitor
the reservoir to assess water quality changes associated with implementation of the NSW
strategies.
Segments 16-41-1-(14), 16-41-1-(0.5) and 16-41-2-(9.5) will remain on the 303(d) list. The Haw
River and New Hope River Arms will be added to the 303(d) list. TMDLs are currently being
developed to address the Impairment in Jordan Reservoir (Chapter 36).
5.3.2 New Hope Creek [AU# 16-41-1-(0.5)a, b, and (11.5)a, b and c]
2000 Recommendations
The 2000 basin plan recommended that DWQ work with the stormwater programs to help
improve water quality in New Hope Creek. DWQ also encouraged smaller facilities to connect
to the regional WWTP where possible.
Current Status
New Hope Creek [16-41-1-(0.5)a] from source to Sandy Creek (17.4 miles) is Supporting
aquatic life because of a Good -Fair benthic community rating at site 1313324.
New Hope Creek [16-41-1-(0.5)b and (11.5)a] from Sandy Creek to SR 2220 (1.1 miles) is
Supporting aquatic life because of a Good -Fair fish community rating at site BF57. The creek
had no intolerant species indicating degraded water quality.
New Hope Creek [I6-41-1-(11.5)b] from SR 2220 to I-40 (3.5 miles) is Impaired for aquatic life
because the dissolved oxygen standard was violated in 13 percent of samples and the turbidity
standard was violated in 12 percent of samples collected during the assessment period at site
BA177. This segment is Not Rated for recreation because fecal coliform bacteria screening
criteria were exceeded at site BA177.
DWQ performed a statistical trend analysis at site BA177 using total nitrogen, total phosphorus
and total suspended solids data collected from 1990 to 2004. There was a significant decrease in
total nitrogen of 0.17 mg/1 per year in New Hope Creek. Downward trends were noted for total
phosphorus and total suspended solids, although these trends were not significant (DENR-DWQ,
trends memo, October 2004).
New Hope Creek [16-41-1-(11.5)c] from 1-40 to SR 1107 (4.0 miles) is Impaired for aquatic life
because of a Fair benthic community rating at site 1313238. The riparian zone was intact at site
1313238, but the banks were steep and eroding and there was little pool and riffle habitat. The
stream also contains trash from the surrounding urban watershed. DWQ completed a fecal
coliform study in New Hope Creek in 2000 and determined that fecal coliform bacteria did not
exceed the standard in this segment. This segment is Supporting recreation because of this
DRAFT Chapter 5 — Cape Fear River Subbasin 03-06-05 • 62

sampling (DENR-DWQ, 2000). There are many single family NPDES permitted discharges in
this watershed that may contributing oxygen consuming wastes as well as bacteria and nutrients.
2005 Recommendations
DWQ will continue to monitor the New Hope Creek to identify stressors to the benthic
community.. DWQ will continue to work with Durham Stormwater program to pursue funding
for BMPs in the New Hope Creek watershed further decrease nutrient loading into Jordan
Reservoir. Further recommendations to protect streams in urbanizing areas and to restore
streams in existing urban areas are discussed in Chapter 31.
Segment 16-41-1-(11.5)b and c remain on the 303(d) list. Segments 16-41-(0.5)a and b and 16-
41-(11.5)a will be removed from the 303(d) list. TMDLs (Chapter 35) will be developed for
identified stressors within 8-13 years of listing.
Water Quality Initiatives
In 1997, the Durham County received a $750,000 CWMTF (Chapter 34) grant to purchase 340
acres of conservation easements along New Hope Creek [16-41-1-(0.5)a] and Mud Creek [16-
41-1-10] in this watershed. The Triangle Land Conservancy (Chapter 34) also received a
$2,750,000 CWMTF grant to acquire 392 acres along the New Hope Creek Greenway. In 1998,
Chapel Hill received a $502,000 CWMTF grant to acquire 105 acres of permanent easements
along Dry Creek [not indexed]. In 1999, EEP (Chapter 34) received a $582,500 CWMTF grant
to stabilize and restore 450 linear feet of Sandy Creek [16-41-1-111 in Duke Forest and to
construct a bioretention areas to treat runoff from 25 acres of urban area. This grant also
included restoration of 8.2 acres of bottomland hardwood wetlands in the New Hope Creek
watershed.
5.3.3 Northeast Creek [AU # 1641-1-17-(0.7)a, b1 and b21
2000 Recommendations
The 2000 basin plan recommended that DWQ work with the stormwater programs to help
improve water quality in Northeast Creek.
Current Status
Northeast Creek [16-41-1-17-(0.7)a], from US 55 to Durham Triangle WWTP (3.3 miles) is
Impaired for aquatic life because the turbidity standard was violated in 15 percent of samples and
the dissolved oxygen standard was violated in 11 percent of samples at sites BA197. This
segment is Supporting recreation because the fecal coliform bacteria standard was not violated
during intensive sampling to assess the standard at site BA197.
Northeast Creek [16-41-1-17-(0.7)bl], from Durham Triangle WWTP to Kit Creek (3.3 miles) is
Impaired for aquatic life because the turbidity standard was violated in 10.3 percent of samples at
site BA209. This segment is Impaired for recreation because the fecal coliform bacteria standard
was violated during intensive sampling to assess the standard at site-BA209.'
Northeast Creek [16-41-1-17-(0.7)b2], from Kit Creek to downstream of Panther Creek (3.2
miles) is Impaired for aquatic life because the turbidity standard was violated in 15 percent of
samples at site BA209. This segment is Supporting for recreation because the fecal coliform
bacteria standard was not violated during intensive sampling at site BA209.
DRAFT Chapter 5 — Cape Fear River Subbasin 03-06-05 63

DWQ developed a fecal coliform bacteria TMDL that was approved by EPA in September 2003.
The TMDL recommended a 90 percent reduction in bacteria loading from urban stormwater in
Durham (Chapter 35).
2005 Recommendations
DWQ will continue to monitor Northeast Creek. DWQ will work with Durham stormwater
services where possible to help reduce the impacts of stormwater and to reduce bacteria loading
by 90 percent. Further recommendations to protect streams in urbanizing areas and to restore
streams in existing urban areas are discussed in Chapter 31.
All three segments will remain on the 303(d) list. TMDLs (Chapter 35) will be developed for
identified stressors within 8-13 years of listing.
5.3.4 Third Fork Creek [AU # 16-41-1-12-(1) and (2)]
2000 Recommendations
The 2000 basin plan recommended that DWQ continue to monitor Third Fork Creek to
determine the impacts of development in the watershed.
Current Status
Third Fork Creek [16-41-1-12-(1)], from source to 2.0 miles upstream of NC 54 (5.2 miles) is
Not Rated on an evaluated basis because Brenntag Southeast Incorporated (NC0086827) failed
whole effluent toxicity (WET) tests five times during the last two years of the assessment period.
The facility is in the headwaters of Third Fork Creek and instream impacts of these failures could
not be assessed. Chemical leaching at Brenntag may be a potential source of toxicity.
Third Fork Creek [16-41-1-12-(2)], from 2.0 miles upstream of NC 54 to New Hope Creek (39
miles) is Impaired for aquatic life because the turbidity standard was violated in 12 percent of
samples collected at site BA178 during the assessment period. This segment is Not Rated for
recreation because the fecal coliform bacteria screening criteria were exceeded at site BA178.
A TMDL (Chapter 35) was approved in January 2005 for total suspended solids that
recommended a 56 percent reduction in TSS mostly from the Durham stormwater system.
2005 Recommendations
DWQ will continue to monitor Third Fork Creek. DWQ will work with Durham stormwater
services where possible to help reduce the impacts of stormwater. DWQ will determine if
intensive sampling is needed to assess the fecal coliform bacteria standard in this creek
(Appendix X). The NPDES compliance process will be used to address the significant permit
violations noted above.
Segment 16-41-1-12-(2) will be added to the 303(d) list. TMDLs (Chapter 35) will be developed
for identified stressors within 8-13 years of listing.

5.4 Status and Recommendations for Waters with Noted Impacts
The surface waters discussed in this section are not Impaired: However, notable water quality
problems and concerns have been documented for some waters based on this assessment. While
these waters are not Impaired, attention and resources should be focused on these waters to
prevent additional degradation or facilitate water quality improvement. Waters in the following
section are identified by assessment unit number (AU#). See overview for more information on
AU#s.
5.41 Beaver Creek [AU# 16-41-10-(0.5)]
Current Status and 2005 Recommendations
Beaver Creek, from NC 55 to SR 1141 (6.0 miles) was not assigned a use support rating during
this assessment period. Beaver Creek drains urbanized areas in and around Apex and is Iikely
impacted by runoff. Further recommendations to protect streams in urbanizing areas and to
restore streams in existing urban areas are discussed in Chapter 31.
Water Quality Initiatives
The Town of Apex (Chapter 34) received a $387,000 CWMTF grant to acquire 43.2 acres of
riparian flood plain to add to 81.6 acres already owned by the town as part of a greenway system.
5.4.2 Cub Creek [AU # 16-41-2-10-(0.5)]
Current Status and 2005 Recommendations
Cub Creek, from the source to downstream of SR 1008 (8.0 miles) is currently Not Rated for
aquatic life on an evaluated basis because Cole Park Plaza (NC0051314) had significant
violations of surfactant permit limits, which could have adversely impacted aquatic life in the
creek. Compliance issues at this facility have not been ongoing. The NPDES compliance
process will continue to be used to address significant permit violations.
5.4.3 White Oak Creek [AU# 1641-6-(0.3) and (0.7)]
Current Status and 2005 Recommendations
White Oak Creek, from source to NC 751 (9.6 miles) is Not Rated for aquatic life a benthic
community rating could not be assigned at site BB314 because the stream dries in summer
months. The benthic community was impacted by 2002 drought conditions. The upper portions
of White Oak Creek drain urbanized in Cary. Further recommendations to protect streams in
urbanizing areas and to restore streams in existing urban areas are discussed in Chapter 31.
Water Quality Initiatives
The Town of Cary (Chapter 34) requires 100-foot buffers on all USGS mapped perennial and
intermittent streams. The buffer requirements will help minimize water quality impacts in the
White Oak Creek watershed as development proceeds. In 2000, Cary (Chapter 34) received an
$86,000 CWMTF grant to produce a greenway feasibility study in the White Oak Creek
watershed. In 2001, Cary received a $1,084,000 CWMTF grant to purchase conservation
easements along 197 acres of White Oak Creek to be part of a greenway system.

5.5 Additional Water Quality Issues within Subbasin 03-06-05
The following section discusses issues that may threaten water quality in the subbasin that are
not specific to particular streams, lakes or reservoirs. The issues discussed may be related to
waters near certain land use activities or within proximity to different pollution sources.
5.5.1 Jordan Haw River Watershed Nutrient Sensitive Waters Strategy
All land uses and discharges of wastewater and stormwater in subbasin 03-06-05 potentially
contribute nutrients to Jordan Reservoir in subbasins 03-06-04 and 03-06-05. The reservoir is
Impaired for aquatic life because chlorophyll a violated the standard in all segments of the
reservoir. Refer to Chapter 36 for more information on this strategy.

Walnut Creek, Swift Creek and Marks Creek
Population growth in this subbasin is one of the highest in
the state. Population density is the highest in the basin
(1,600-3,200 persons/mi2). The largest urbanized area is
in the northern portion of the subbasin around Raleigh and
Cary. New development can be seen in all areas of the
subbasin, but especially along the I-40/Hwy 70 corridors
and US 64 corridor.
There are 19,345 acres of managed public lands in this
subbasin, with Umstead Park and Schenk Forest being the
largest. There are also smaller parks and several
greenways in this subbasin.
There are 52 NPDES wastewater discharge permits in this
subbasin with a permitted flow of 87 MGD (Figure B-2).
The largest are Raleigh Neuse WWTP (60 MGD, map
#154), Central Johnston WWTP (4.5 MGD, map #96),
Cary North WWTP (12 MGD, map #172), Little Creek
WWTP (1.9 MGD, map #129) and Wake Forest WWTP
(2.4 MGD, map #191). There are also five individual
NPDES stormwater permits in the subbasin. Refer to
Appendix I for identification and more information on
individual NPDES permit holders. Raleigh has a Phase I
stormwater permit, and Cary, Apex, Garner, Durham
County and Wake County will be required to develop a stormwater program under Phase II (page
76). Smithfield and Johnston County, and the above communities, have also submitted model
stormwater ordinances as required by the Neuse NSW strategy stormwater rules (page 64).
Issues related to compliance with permit conditions are discussed below in Part 2.3 or Part 2.4
for impaired waters and in Part 2.5 for other waters. There are also nine registered animal
operations in this subbasin.
There were 17 benthic macroinvertebrate community samples and five fish community samples
(Figure B-2 and Table B-4) collected in 2000 as part of basinwide monitoring. Six sites
improved, 13 sites remained the same, and two sites had lower bioclassifications. One site was
monitored for the first time. There were also 30 special study samples collected in the subbasin
during the assessment period. Data were collected from nine ambient monitoring stations as
well.

Refer to Appendix III for a complete list of monitored waters by use support category and more
information on supporting monitored waters.
2.2 Use Support Summary
Use support ratings (page 54) in subbasin 03-04-02 were assigned for aquatic life and secondary
recreation, fish consumption, primary recreation and water supply. All waters in the subbasin are
considered impaired on an evaluated basis because of fish consumption advisories (page 93). All
water supply waters are supporting on an evaluated basis based on reports from DEH regional
water treatment consultants.
There were 243 stream miles (47 percent) and 1,065 reservoir acres (95 percent) monitored
during this assessment period in the aquatic life and secondary recreation use support category.
Approximately 68 (28 percent) of the monitored stream miles are impaired. Refer to_Table B-5
for a summary of use support ratings by use support category for waters in the subbasin. Use
support ratings for waters that were monitored and impaired in at least one use support category
or were impaired in 1998 are presented in Table B-6.

2.3 Status and Recommendations of Previously Impaired Waters
2.3.1 Black Creek
1998 Recommendations ' ' '
Black Creek was partially supporting from the source to Crabtree Creek. It was recommended
that the City of Raleigh address urban runoff impacts to this stream.
Current Status
Black Creek (3.6 miles) is currently impaired because of a Fair bioclassification at site SB-5.
Habitat degradation from urban runoff is a likely cause of impairment.
2002 Recommendations
DWQ will continue monitoring Black Creek. As part of the 303(d) list approach, DWQ will
begin the process of identifying problem parameters that may be causing biological impairment
in Black Creek. Because of the water quality impairment noted above, Black Creek is a NCWRP
targeted local watershed (page 203).
The impaired biological community in Black Creek is typical of streams that run through urban
areas. As with Crabtree Creek and the other creeks draining urban Raleigh and Cary, great
efforts will be needed to reduce impacts from urban runoff. Refer to page 81 for a description of
urban stream problems and recommendations for reducing impacts and restoring water quality.
2.3.2 Crabtree Creek
1998 Recommendations
Crabtree Creek was not supporting from the source to I-40 and partially supporting and fully
supporting from Highway 70 to the Neuse River. It was recommended that Cary and Raleigh
address the.stormwater impacts to Crabtree Creek. Development has continued in the Crabtree
Creek watershed.
Current Status
Crabtree Creek (5.1 miles) from the source to Lake Crabtree is currently impaired because of a
Poor bioclassification at site B-6. This segment is affected by urban runoff from Cary: From the
Cary WWTP outfall to Hair Snipe Creek (14 miles), the creek is supporting because of a Good -
Fair and Excellent bioclassifications at two sites in Umstead State Park (B-7 and F-2) indicating
recovery of water quality through the undeveloped parkland. These sites are downstream of Cary
WWTP and Crabtree Lake. The ambient monitoring station (A-3) in the park detected elevated
turbidity and iron, indicating erosion of soils most likely from upstream construction sites and
streambank erosion. From Hair Snipe Creek to 2.8 miles upstream of the Neuse River (10.9
miles), Crabtree Creek is impaired because of a Fair bioclassification at site B-8. This segment
drains the highly urbanized watersheds of Raleigh. The ambient monitoring station (A-4) also
detected elevated turbidity and iron. All the monitored tributaries to Crabtree Creek received
Poor or Fair bioclassifications. Habitat degradation (page 89) is a likely cause of the impaired
biological communities in these segments of Crabtree Creek.
Section B: Chapter 2 — Neuse Subbasin 03-04-02 114

2002 Recommendations
DWQ will continue monitoring Crabtree Creek. As part of the 303(d) list approach, DWQ will
begin the process of identifying problem parameters that may be causing biological impairment
in Crabtree Creek. DWQ will continue to support the City of Raleigh stormwater programs.
Because of the water quality impairment noted above, Crabtree Creek is a NCWRP targeted local
watershed (page 203).
The impaired biological community in Crabtree Creek is typical of streams that run through
urban areas. Refer to page 81 for a description of urban stream problems and recommendations
for reducing impacts and restoring water quality.
As can be seen by the water quality improvement in Umstead Park, undisturbed land with little
impervious surface area can help to maintain aquatic habitats and the integrity of the biological
community.
Current Water OualiU Initiatives
The City of Raleigh has established the Capital Area Greenway (page 214) on segments of
Crabtree Creek that will help to preserve buffers along the mainstem of the creek and provide
recreational opportunities.
The Neuse River Foundation (page 214) has been monitoring the mouth of Crabtree Creek to
investigate sediment and nutrient loading from the Crabtree Creek watershed into the Neuse
River.
2.3.3 Hair Snipe Creek
1998 Recommendations k
Hair Snipe Creek was partially supporting from the source to Crabtree Creek. It was
recommended that the City of Raleigh address urban runoff impacts to this stream.
Current Status
The bioclassification of Hair Snipe Creek has dropped to Poor at site SB-7, indicating increased
impacts from urban runoff. Hair Snipe Creek (4.5 miles) is currently impaired because of the
Poor bioclassification, likely because of habitat degradation and urban runoff.
2002 Recommendations

more detailed study of the watershed be undertaken to determine possible causes of impairment.
Current Status
Little Creek (11.4 miles) is currently impaired because of a Fair bioclassification at site B-17.
This stream has a noted lack of habitat, but may be improving as indicated by the presence of
more intolerant macroin vertebrates than in previous monitoring. Little Creek drains the rapidly
urbanizing watershed west of Clayton and may be impacted by development in the area.
2002 Recommendations
Little Creek watershed is under high development pressure. Sedimentation and erosion control
plans should be followed during construction to minimize impacts to Little Creek and its
tributaries. As part of the 303(d) list approach, DWQ will begin the process of identifying
problem parameters that may be causing biological impairment in Little Creek. Refer to page 81
for a description of urban stream problems and recommendations for reducing impacts and
restoring water quality.

Section B: Chapter 2 — Neuse Subbasin 03-04-02 117

2.3.8 Pigeon House Branch
1998 Recommendations
Pigeon House Branch was not supporting from the source to Crabtree Creek. It was
recommended that the City of Raleigh address urban runoff impacts to this stream.
Current Status
Pigeon House Branch (2.9 miles) is currently impaired because of a Poor bioclassification at site
SB-15. Habitat degradation from urban runoff is the most likely cause of impairment. At the
ambient monitoring station (A-5), the geometric mean of fecal coliform bacteria was 900
colonies1100m1 water. This stream drains downtown Raleigh and is under parking lots or large
roadways for much of its length.
2002 Recommendations
DWQ will continue monitoring Pigeon House Branch. As part of the 303(d) list approach, DWQ
will begin the process of identifying problem parameters that may be causing biological . -
impairment in Pigeon House Branch. Because of the water quality impairment noted above,
Pigeon House Branch is a NCWRP targeted local watershed (page 203).
The impaired biological community in Pigeon House Branch is typical of streams that run
through urban areas. As with Crabtree Creek and the other creeks draining urban Raleigh and
Cary, great efforts will be needed to reduce impacts from urban runoff. Refer to page 81 for a
description of urban stream problems and recommendations for reducing impacts and restoring
water quality.
2.3.9 Swift Creek (including Williams Creek)
1998 Recommendations
Upper Swift Creek and Williams Creek were not supporting from their sources to Lake Wheeler.
Swift Creek was partially supporting from Lake Wheeler to Lake Benson and fully supporting to
the Neuse River. It was recommended that no new discharges be permitted into the creek.
Current Status
Upper Swift Creek and Williams Creek are currently not rated because these segments are too
small to assign bioclassifications. Swift Creek (5.5 miles) from the confluence with Williams
Creek to Lake Wheeler is currently impaired because of Poor and Fair bioclassifications at sites
SB-3 and B-14.
Between Lake Wheeler and Lake Benson (2.4 miles), Swift Creek is also impaired because
dissolved oxygen (site A-18) was below 4 mg/l in 10.1 percent of samples. Swift Creek is being
investigated by the Watershed Assessment and Restoration Project (WARP) (page 213). Above
Lake Wheeler, Swift Creek is adversely impacted by stonnwater runoff from urban and
developing areas of Raleigh and Cary.
2002 Recommendations
DWQ will continue monitoring Swift Creek. As part of the 303(d) list approach, DWQ will
begin the process of identifying problem parameters that may be causing biological impairment
Section B: Chapter 2 — Neuse Subbasin 03-04-02 118

in Swift Creek. DWQ will use the information in the WARP report on Swift Creek to develop',
recommendations to restore water quality in Swift Creek.
The impaired biological community in Swift Creek is typical of streams that run through urban
areas. As with Crabtree Creek and the other creeks draining urban Raleigh and Cary, great
efforts will be needed to reduce impacts from urban runoff. Refer to page 81 for a description of
urban stream problems and recommendations for reducing impacts and restoring water quality.
Lower Swift Creek, below the Lake Wheeler Dam, is being studied for preservation by the
Triangle Land Conservancy. Because of the water quality impairment noted above and the
preservation efforts, lower Swift Creek is a NCWRP targeted local watershed (page 203).
Current Water Quality Initiatives
There is Wake County Parks and Recreation and CWMTF restoration project (page 218) in the
Swift Creek watershed. The Triangle Land Conservancy (page 219) has prepared a conservation
assessment for the Conservation Trust for North Carolina (page 218) that identifies preservation
and restoration opportunities in Swift Creek and the adjacent Neuse River watershed.
2.3.10 Toms Creek
1998 Recommendations
Toms Creek was partially supporting from the source to the Neuse River. No specific
recommendations were made for Toms Creek in the 1998 basinwide plan.
Current Status
Toms Creek (1.5 miles) from Browns Lake to the Neuse River is currently impaired because of a
Fair bioclassification at site B-4. Toms Creek was investigated by the Watershed Assessment
and Restoration Project (WARP) (page 213) in 2001. The watershed assessment was valuable in
defining the extent of impairment in Toms Creek and in determining the causes of impairment.
Extensive monitoring completed during the project determined that high chlorine levels in the
Deerchase WWTP (map #197) discharge and habitat degradation from high stormwater flows in
the lower part of the creek are responsible for the impairment.
2002 Recommendations
In order to restore the biological community in Toms Creek, the discharger problems need to be
addressed, and then aquatic. habitat will need to be restored below the dam at Browns Lake.
DWQ will work with Deerchase WWTP to reduce impacts to Toms Creek related to the
discharge. Current NSW riparian buffer rules (page 64) and the NSW and NPDES Phase II
(page 76) stormwater rules need to be fully enforced to prevent increased habitat degradation in
Toms Creek. Because of the water quality impairment noted above and the current assessment
efforts, Toms Creek is a NCWRP targeted local watershed (page 203).
Section B: Chapter 2 — Neuse Subbasin 03-04-02 119

2.3.11 Walnut Creek
1998 Recommendations
Walnut Creek was partially supporting from Lake Johnson to Lake Raleigh and from I-440 to the
Neuse River. The segment between these was not supporting. It was recommended that no new
discharges be permitted into the creek.
Current Status
Increases in bioclassification to Good -Fair at two sites below Lake Raleigh (B-10 and F-3)
indicate some improvement in water quality lower on Walnut Creek. This segment is currently
supporting because of the increased bioclassifications; however, there was noted habitat
degradation with infrequent pools and riffles and indications of scour from high storm flows.
The segments above I-440 are currently not rated because there was no monitoring, and the area
drains heavily urbanized portions of Cary and Raleigh. Past benthic macroinvertebrate
bioclassifications have been Poor upstream of site F-3. Upper Walnut Creek is heavily impacted
from urban runoff.
2002 Recommendations
Although water quality in Walnut Creek appears to be improving in the lower segments, the
watershed drains urbanized and urbanizing areas of Raleigh and Cary and the potential for
degradation of instream habitat is very high. DWQ will reestablish a biological monitoring
station above Lake Raleigh and Lake Johnson to better assess impacts from stormwater runoff.
Refer to page 81 for a description of urban stream problems and recommendations for reducing
impacts and restoring water quality.
There are currently two NCWRP restoration projects ongoing in the Walnut Creek watershed
(page 213) designed to stabilize streambanks and reduce sedimentation. Because of the water
quality impairment noted above and the current restoration projects, Walnut.Creek is a NCWRP-
targeted Iocal watershed (page 203).
2.4 Status and Recommendations for Newly Impaired Waters
2.4.1 Richlands Creek
Current Status
Richlands Creek was fully supporting but threatened in 1998, but is currently impaired (4.7
miles) because of two Fair bioclassifications in 1996 at sites SB-4 and SB-6. Habitat
degradation from urban runoff is the most likely cause of impairment. Intensive grading and
road building activity in this watershed, related to construction of the Raleigh Entertainment and
Sports Arena (RESA), is likely to have increased habitat degradation.
2002 Recommendations
DWQ will continue monitoring Richlands Creek. As part of the 303(d)-list approach, DWQ will
begin the process of identifying problem parameters that may be causing biological impairment
in Richlands Creek. The NCWRP is initiating a riparian buffer restoration and streambank
stabilization project on Richlands Creek at the RESA. Because of the water quality impairment
Section B: Chapter 2 — Neuse Subbasin 03-04-02 120

noted above and the current restoration efforts, Richlands Creek is a NCWRP targeted local
watershed (page 203).
The impaired biological community in Richlands Creek is typical of streams that run through
urban areas. As with Crabtree Creek and the other creeks draining urban Raleigh and Cary, great
efforts will be needed to reduce impacts from urban runoff. Refer to page 81 for a description of
urban stream problems and recommendations for reducing impacts and restoring water quality.
2.5 Status and Recommendations for Waters with Noted Impacts
The surface waters discussed in this section are supporting designated uses (unless otherwise
noted) based on DWQ's use support assessment and are not considered to be impaired.
However, notable water quality problems and concerns have been documented for some waters
based on this assessment. While these waters are not considered impaired, attention and
resources should be focused on these waters to prevent additional degradation or facilitate water
quality improvement.
2.5.1 Reedy Creek
Current Status and 2002 Recommendations
Reedy Creek was not rated in 1998 and is currently not rated. Site SB-24 did not meet the
necessary criteria to assign a bioclassification. The watershed drains urbanizing portions of
Raleigh. Refer to page 81 for a description of urban stream problems and recommendations for
reducing impacts and -restoring water quality.
2.5.2 Rocky Branch
Current Status and 2002 Recommendations
Rocky Branch is currently not rated. Sites SB-20, 21 and 22 did not meet the necessary criteria
to assign bioclassifications. The watershed is in a heavily urbanized area of west Raleigh and
runs through NCSU campus. Stream habitat is degraded, and the benthic macroinvertebrate 1
community is heavily impacted from urban runoff. The stream is currently undergoing a large-
scale restoration project funded in part by CWMTF (page 210).
2.5.3 Lake Crabtree
Current Status and 2002 Recommendations
Lake Crabtree has constantly high turbidity, most likely from urban runoff and development in
the watershed. The watershed drains urban Cary and Raleigh -Durham International Airport.
Lake Crabtree may actually help downstream water quality by processing sediment and nutrients
and reducing turbidity. There was a blue green algal bloom in the lake in August 1999. DWQ
will continue to monitor the lake to evaluate any future degradation in water quality.
Lake Crabtree (518 ac) is classified for and is supporting primary recreation based on a lake
assessment completed in summer of 2000. Fecal coliform bacteria levels were well below the
water quality standard for primary recreation.
Section B: Chapter 2 — Neuse Subbasin 03-04-02 121

2.5.4 Reedy Creek Lake, Big Lake and Sycamore Lake
Current Status and 2002 Recommendations
Reedy Creek Lake,'Big Lake and Sycamore Lake have had problems with Hydrilla. The
watersheds drain mostly forested areas of Umstead State Park. There are indications of increased
nutrient loading to the lakes as development increases in the watershed areas just outside of the
park boundaries. DWQ will continue to monitor these lakes to evaluate any future degradation in
water quality that may be associated with development in these watersheds.
2.5.5 Apex Lake
Current Status and 2002 Recommendations
Apex Lake watershed has undergone dramatic development since 1995. Nutrient and sediment
loading to the lake are increasing as a result of this development. Because of the rapid changes
in land use in this watershed, DWQ will continue to monitor this lake to evaluate any future
degradation in water quality that may be associated with development.
2.5.5 Lake Wheeler
Current Status and 2002 Recommendations
Lake Wheeler is an important recreational lake as well as a future Raleigh water supply. There
are safety and pollution concerns related to the use of powerboats on the lake. There have been
high levels of manganese detected in the lake, and Hydrilla infestations have also been a
problem. Because of the rapid changes in land use in this watershed, DWQ will continue to
monitor this lake to evaluate any future degradation in water quality that may be associated with
development.
2.5.7 Lake Benson
Current Status and 2002 Recommendations
Lake Benson is a future Raleigh water supply. There have been high levels of manganese
detected in the lake, and Hydrilla infestations have also been a problem. Because -of the rapid
changes in land use in this watershed, DWQ will continue to monitor this lake to evaluate any
future degradation in water quality that may be associated with development.
2.5.8 Marks Creek
Current Status and 2002 Recommendations
Marks Creek is in rapidly developing areas of Wake and Johnston counties. There was logging
noted at sites B-13 and F-4. Adherence to and enforcement of riparian buffer and stormwater
rules will help to protect Marks Creek as this watershed is developed. Because of the water
quality impacts noted above, the increasing development pressure and the availability of a
conservation assessment in the watershed, Marks Creek is a NCWRP targeted local watershed
(page 203).
Section B: Chapter 2 — Neuse Subbasin 03-04-02 122

The Triangle Land Conservancy (page 219) has prepared a conservation assessment for the
Conservation Trust for North Carolina (page 218) that identifies preservation and restoration
opportunities in Marks Creek and the adjacent Neuse River watershed (page 214).
2.5.9 Neuse River Bottomlands
Current Status and 2002 Recommendations
This section of the Neuse River is currently supporting based on a Good bioclassification at site
B-12. This segment of the Neuse River is the best watershed for preservation in the upper Neuse
River basin. More than 50 percent of the entire basin population live upstream of this site. This
area has extensive wetlands and will be an important area to preserve to protect downstream
water quality. The Neuse River floodplain broadens out to four miles wide through this area as it
transitions from the piedmont to the coastal plain. This watershed has several Natural Heritage
sites and has been prioritized by Johnston County as its most impressive natural area, The
NCWRP has targeted this local watershed (page 203).
2.5.10 Richland Creek
Current Status and 2002 Recommendations
Richland Creek is in a rapidly developing area near Wake Forest. Two sites on Richland Creek
had Good -Fair bioclassifications. Adherence to and enforcement of riparian buffer and
stormwater rules will help to protect Richland Creek as this watershed is developed. Because of
the increasing development pressure, this watershed is a NCWRP targeted local watershed (page
203).
2.6 Additional Water Quality issues Within Subbasin 03-04-02
This section discusses issues that may threaten water quality in the subbasin that are not specific
to particular streams, lakes or reservoirs. The issues discussed may be related to waters near
certain land use activities or within proximity to different pollution sources.
2.6.1 Water Quality Threats to Streams in Urbanizing Watersheds
Most of the streams in this subbasin that are not already impaired from urban stormwater runoff
are threatened by development pressure throughout this subbasin. In order to prevent aquatic
habitat degradation and impaired biological communities, protection measures must be put in
place immediately. Refer to page 81 for a description of urban stream water quality problems
and recommendations for reducing impacts to and restoring water quality in these waters.
2.6.2 Wake County Watershed Task Force
Local governments have increasingly become involved in water quality issues within their
jurisdictions. Wake County is centered in one of the most intensely developed subbasins in
North Carolina. Wake County is engaged in a process to protect and restore water quality to
streams in the county (page 218).

GENERAL DESCRIPTION & APPLICATIONS
'in compounds are classified into two main groups; inorganic -tin and organo-tin compounds.
'he organo-tin compounds are defined as compounds in which at least one tin -to -carbon
pond exist. But the inorganic -tin compounds do not contain carbon as the principal element.
norganic-tin compounds are relatively simple in their molecular structure and, like tin itself,
)re not considered to be toxic. Tin atoms can replace carbon atoms in chemical
-ompounds, and a great variety of organo-tin compounds are known.
ORGANIC TIN COMPOUNDS
'he largest use for inorganic tin compounds is in electrolytes for plating tin and tin alloys. The
Tiore important plating chemicals are chlorides, sulfates, and fluoroborates in acidic
,lectrolytes and stannates,in alkaline solutions. Chemically, tin exhibits valencies of 2 and 4.
norganic-tin compounds are divided into two series: stannous, or tin(II), compounds which
-ontain tin as a quadrivalent element, whereas stannic, or tin (IV), compounds containing tin
:is a bivalent element. It resists attack by water but is dissolved by strong acids and alkalis.
Dne of common compounds of tin(II) are stannous chloride (SnC12) used in tin galvanizing, as
reducing agent in the manufacture of polymers and as a mordant in dyeing.; stannous
)xide (SnO) employed in making tin salts for chemical reagents and for plating; and stannou

joride (SnF2) is the additive in fluoride tooth -pastes. Inorganic tin chemicals are used as
atalysts in a number of industrial processes. stannous octoate is the catalyst that produces
ie foaming action that turns the liquid plastic into a foam -like solid structure in the
ionufacture of polyurethane foam. Tin(IV) compounds of significance include stannic
hloride (SnC14) is widely used as a stabilizer for perfumes and as a starting material for other
n salts; and stannic oxide(Sn02) is a useful catalyst in certain industrial processes and a
olishing powder for steel. Tin sulfide is used as a bronzing agent for wood col6uring
COMPOUNDS
'he greatest use of di-organotin compounds is stabilizers in the manufacture of polyvinyl
chloride, or PVC. The particular importance of these di-organotins lies in their outstanding
ability to preserve the clarity and transparency of PVC, not only when being processed but
)Iso in subsequent service. Organ oti n-stabilized PVC is used in water pipes and in food
Dackaging applications as tin compounds used in these applications are known as nontoxic,
n contrast to the nontoxic compounds employed as stabilizers, some tri-organotin
compounds (e.g., tributyl- and triphenyltins) are powerful biocides and have found use in a
lumber of relevant applications, such as fungicides bactericide in underwater and
anti -fouling paints, preservatives for wood, textile, paper, leather, and glass, and hospital and
teterinary disinfectants. The tributyltin family of chemicals include bis (tributyltin) oxide, or
ributyltin oxide itself, tributyltin sulfide, bis (tributyltin) adipate, tributyltin methacrylate,
ributyltin fluoride, and tributyltin acetate. Tributyltin derivatives have toxic properties to gram
)ositive bacteria are used as disinfectants on surfaces such as hospital floors and sports
5renas, combined with gram negative bactericides. Tin chemicals also used as flame
etardants to treat fabrics and plastics.
