Rocky River — Recommendations
Issues in the basin
- Need for Siler City to have TN limits
Potential Studies within this basin
- Need to identify sources of nutrient loading into this system
Agricultural Community
Siler City WWTP
Urban Stormwater
- Assess smaller sub-watersheds. See what the loading is from the smaller watersheds in
order to find the areas of greatest nutrient contributions and then implement appropriate
reductions strategies (BMPs).
- Start assessment and restoration/implementation in the upper portion of the watershed
and work down the basin overtime.
- Documentation of periphyton growth throughout the basin. Visual/photo
documentation over time. Natural or not? This could be quantitative or qualitative.
- Flow and biomass assessment study. Assessment of dam pulse releases on the aquatic
vegetation. This could be quantitative or qualitative.
- Chlorophyll a assessment of impoundment just above confluence with Bear Creek.
Hydroelectric dam (Luther Allen); run of the river impoundment.
(Need for access to the dam in order to collect samples for chlorophyll a
assessment.)
- New impairment of the Upper Rocky River Reservoir
- High nutrients throughout the entire basin
- Aesthetics?
- Oder?
- Loss of use?
- Spatial extend of high periphyton growth throughout the system
- Lack of flushing due to drought over the last several years
- Slate belt streams - Natural conditions?
- Impairment behind Buckhorn Dam on the Cape Fear River; need for nutrient reductions

Dear Sirs:
North Carolina Division of Water Quality
Please respond to the following numbered items for the Raleigh Regional Office’s consideration and
please provide any additional information you wish to offer:
As a part ot this meeting, questions were raised that specifically referenced conditions, monitoring and
documentation requirements of the 401 Certification. Accordingly, it was agreed that the RRO would
request, by copy of this letter, that the Town of Siler City provide information that explained 401 Water
Quality Certification condition implementation.
On February 4, 2009, the Division of Water Quality staff met with the Town of Siler City, members of
the Friends of Rocky River, and other interested parties to discuss the Subject 401 Water Quality
Certification and other issues common to the Rocky River.
Beverly Eaves Perdue
Governor
4)A pulse is only required when no natural events of similar magnitude are observed. Please explain
how this will be determined. (It is the RRO’s recommendation that the Town use the USGS
station records to document the presence or absence of natural pulse events.)
3) How is the Town planning to document pulse flow (start, duration, USGS gauge response
recording, monitoring stations)?
2)Condition 3 defines a pulse as 20cfs for a 12 hour period. The “pulse” frequency is limited to one
(1) pulse every 30 days. Please explain how the Town will document flows and insure
compliance with the 30 day pulse frequency requirement.
1)Please explain/address the Town’s plan to keep records [e.g. electronic records in an excel
spreadsheet format of daily changes in releases at the dam].

12. It was observed during the inspection that the oxidation ditches had more than 25% of foam
covering the surface area. The ORC indicated the oxidation ditch employs jet aeration for the
method of dissolved oxygen delivery. This type of aeration can cause excessive turbulence,
leading to excessive foaming; utilizing a blower/diffused aeration or mechanical aeration can
decrease this turbulence, decreasing the amount of foam production.
Meritech Laboratories is contracted to test metals, MBAS, TN/TP and chronic toxicity. The other
parameters are analyzed in-house.
A file review of the plant records indicated that all records are being kept as required. A
comparison of the February 2010 DMR indicated no discrepancies.

13. Stormwater Permit Number NCG110085 stormwater records were reviewed and found to be
satisfactory. Both stormwater outfalls were observed during the inspection and no problems
were noted.

There is currently not enough standby power to operate the entire facility. The generator can only
operate the influent pump station, bar screen and grit removal process. The generator is tested by
interrupting the power source weekly and under load monthly.
10. The facility currently uses chlorine gas for disinfection. Please consider for future upgrades the
feasibility of an ultraviolet (UV) system.

An Equal Opportunity/Affirmative Action Employer - 50% Recycled/10% Post Consumer Paper
On June 9 and 10, 2010, Vicki Webb and Tom Ascenzo (on June 10lh) of the Raleigh Regional Office
conducted a compliance evaluation inspection of the Town of Siler City’s collection system with the
assistance of Mr. Terry Green, operator in responsible charge (ORC), Mr. Joey Smith, back-up ORC,
Mr. Barry Rogers from the wastewater treatment plant (WWTP). Their help was appreciated as it
facilitated the inspection process.
Beverly Eaves Perdue
Governor
4. The Town has a system wide map of the collection system. The map includes all the required
components as required in Section III Records (3) of the permit.
5. The Town’s Capital Improvement Plan (CIP) was reviewed. The plan contained a description of
existing facilities, a description of known deficiencies and forecast of future needs.
2. The Town’s grease ordinance and inspection program were discussed. The Town has a grease
ordinance and the restaurants have installed grease traps. Joey Smith is the Town’s code
enforcement officer and inspector. Mr. Smith’s records of inspections are well organized.
1. The Town of Siler City’s collection system is classified as a “Class 2” collection system. It has
approximately 50 miles of gravity sewer, approximately 4 miles of force main, 5 simplex pump
stations and 8 duplex pump stations. The permit expires April 30, 2012. Update your permit to
reflect the correct amount of pump stations.

6. The permit requires that 10% of the gravity lines be cleaned every year. Records for 2009
indicated 34,081 feet were cleaned which meets the requirement. The Town is expected to clean
-26,400 feet each year. Mr. Green stated that they clean trouble spots more often to prevent
problems. If a problem is noted in the line an internal form is completed and given to the Public
Works Director. The cleaning records indicated that the date and amount cleaned was recorded.
7. The Town had records on file of all its reported overflows and press release information. The
records on file also documented when high priority lines had been inspected and right of ways
had been mowed.

2. Basic Machinery Pump Station - The Basic Machinery duplex pump station is located at 1045
Andrews Road and is secure with a fence and has proper signage on the fence gate. The wet well
was free of excessive debris and grease. This station has a quick connect in case a portable
generator is needed. This is the only pump station that has float controls instead of the bubbler
system. The alarms were tested during the inspection. Records of twice daily visitation were
available on site.
4. Singing Sound Way Pump Station - The Singing Sound Way duplex pump station is located at
1722 Singing Sound Way and is secure with a fence and has proper signage on the fence gate.
The wet well had excessive debris and grease. Both Gorman Rupp submersible pumps were
present and operational. The alarms were tested during the inspection. This station has a quick
connect in case a portable generator is needed. There is also a connection in case the wet well
needed to be pumped by a vac truck if there was a loss of power. Records of twice daily
visitation were available on site.
5. Blood Run Pump Station - The Blood Run duplex pump station is located at 300 Elder Road and
is secure with a fence and has proper signage on the fence gate. The wet well had excessive
debris and grease. Both Gorman Rupp dry pit submersible pumps were present and operational.
The alarms were tested during the inspection. Records of twice daily visitation were available on
site.
3. Chatham Pump Station - The Chatham duplex pump station is located at 1815 North Chatham
Avenue and is secure with a fence and has proper signage on the fence gate. The wet well had
excessive debris and grease. Both Gorman Rupp pumps were present and operational. The
alarms were tested during the inspection. This station has a quick connect in case a portable
generator is needed. Records of twice daily visitation were available on site.
All of the eight duplex pump stations along with several sewer right-of-ways (ROW), manholes and
aerial lines were inspected. The following items were noted:
1. North Avenue Pump Station - The North Avenue duplex pump station is located at 1411 North
Avenue and is secure with a fence and has proper signage on the fence gate. The wet well was
free of excessive debris and grease. This station as well as the others unless noted utilize a
bubbler type mechanism for signaling pumps to turn on/off and alarm conditions. Both Gorman
Rupp pumps were present and operational. This pump station as well as the others unless noted
has a telemetry system, audible and visual alarms. The alarms were tested during the inspection.
There is a generator on-site and is tested and monitored for fuel on a regular schedule. Records
of twice daily visitation were available on site.

11. It was observed during the inspection that the comer of E 9th and E 10111 Street has a line that goes
across the ditch at an angle and then runs along the road. Looking closer at this line, it showed
Aerial Lines - The aerial lines for Behind Bo jangles. Cape Carnes, Lowes Food, Justice MHP,
Jordan Mathews High School, Armory, Wal-mart, U Auto Wash III, Bridge at Hatchery, Behind
D.O.T., Gary Smith Pasture, Across from Gold Kist, Jimmy Price-old bowling, and South 6th St.
were inspected. All of the lines were free of visible damage and all supports were in good
condition unless noted below. The right-of-way is accessible. The line at Cape Carnes was hard
to have a clear view due to brush growing on both sides of the pipe. ROW was well maintained. I
recommend cleaning around this aerial line for better visual inspections. The line at Armory,
Behind D.O.T., and Jimmy Price-old bowling is dead (not in use). The line at Wal-mart was
difficult to see from both sides due to over grown brush/trees. This is in need of immediate
attention in order to properly view/inspect. The line at U Auto Wash III is in danger of being
over taken by the kudzu vines. These lines are being inspected as required. Mr. Green takes
pictures that are time and date stamped each time he inspects the high priority lines.
Technology Way Pump Station - The Technology Way duplex pump station is located at 217
Technology Way and is secure with a fence and has proper signage on the fence gate. The wet
well had excessive debris and grease. Both Gorman Rupp pumps were present and operational.
The alarms were tested during the inspection. There is a generator on-site and is tested and
monitored for fuel on a regular schedule. Records of twice daily visitation were available on site.
Progress Blvd Pump Station - The Progress Blvd duplex pump station is located at 305 Progress
Blvd and is secure with a fence and has proper signage on the fence gate. The wet well had
excessive debris and grease. Both Gorman Rupp pumps were present and operational. The
alarms were tested during the inspection. There is a generator on-site and is tested and monitored
for fuel on a regular schedule. Records of twice daily visitation were available on site.
Water Treatment Plant Pump Station - The Progress Blvd duplex pump station is located at 955
Water Plant Rd and is secure with a fence. The pump station does not have proper signage on the
fence gate. The wet well was free of excessive debris and grease. Both Gorman Rupp pumps
were present and operational. There is a generator on-site. The alarms were tested during the
inspection. Both the audible and the visual alarms did not work. The telemetry was not
installed and thus not working at the time of the inspection. Refer to WQCS00056 Permit
Section V. Inspection 2; it states: Pump stations without Supervisory Control and Data
Acquisition (SCADA) systems or telemetry shall be inspected everyday (i.e. 365 days per
year). Pump stations equipped with SCADA systems or telemetry shall be inspected at least
once per week. This pump station does not have a contingency plan or records of testing
the generator or testing of alarms. Before I left the facility, the visual alarm was repaired.
Please let this office know the time line of this pump station having the telemetry installed
and when the audible alarm repaired. Start keeping records of all vital information that is
related to all pump stations.

10. Other - The right-of-way (ROW) and manholes (MH) were observed at 84 Lumber, South 6111
St., Loves Creek, Loves Creek - Justice tie in, and Water treatment plant. The right-of-ways are
well maintained and accessible. The only concern for the ROWs is the tree canopy. If not cut
back in the next year to two years, could cause problems should you ever need equipment to go
down the ROW. This was discussed with Mr. Green at the end of the inspection. The manholes
observed were free of visible signs of overflows, grease, roots and excessive sand. All manhole
covers were present and seated properly. Manholes were also observed upstream of each pump
station.
