Dear Mr. Dodson:
Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly,
we are forwarding the attached NPDES discharge 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
U.S. Environmental Protection Agency dated May 9,1994 (or as subsequently amended).
The following modifications from the draft permit are included in the final permit:
• Fluoride monitoring was changed to monthly. The draft permit specified 2/month instead of
monthly as proposed in the fact sheet.
• Nutrient monitoring frequency was modified to weekly.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you,
you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this
letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North
Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to
obtain other permits which may be required by the Division of Water Quality or permits required by the Division

A. (3.) PROVISIONAL WAIVER OF INSTREAM MONITORING REQUIREMENTS
Instream monitoring requirements in this NPDES permit shall be provisionally waived so long as the
Permittee remains a member of the Upper Cape Fear River Basin Association and the Association
continues to function as approved by the Division and Environmental Management Commission. If the
Permittee does not participate in the Association or if the Association ceases to function, the instream
monitoring requirements in this permit become effective immediately; and the Division may reopen this
permit by administrative letter to establish additional instream monitoring requirements it deems necessary
to adequately characterize the effects of the discharges on water quality in the receiving stream.

Permit NC0047597
ti.
A. (4.) CALCULATIONS OF MASS LOADS
a. The permitte shall calculate monthly and annual TN (or TP) loads as follows:
i. Monthly TN (or TP) Loads = TN (or TP) x TMF x 8.34
Where:
TN (or TP) = the average Total Nitrogen (or Total Phosphorus) concentration (mg/L) of
the composite samples collected during the month.
TMF = the total monthly flow of wastewater discharged during the month
(MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN (or TP) Load (lb/yr) = Sum of 12 monthly TN (or TP) Loads for calendar
year.
b. The permitte shall report monthly total nitrogen and total phosphorus results (mg/L and lb/mo)
in the appropriate discharge monitoring report for each month and shall report each year's
results (lb/yr) with the December report for that year.
A. (5). NUTRIENT MONITORING RE -OPENER
Pursuant to N.C. Gen. Stat. Section 143-215.1 and the implementing rules found in Title 15A of the
North Carolina Administrative Code, Subchapter 2H, specifically, 15A NCAC 2H.0112(b)(1) and
2H.0114(a), and Part II, Sections B-12 and B-13 of this Permit, the Director of DWQ may reopen this
permit to require supplemental nutrient monitoring of the discharge. The additional monitoring will be to
support water quality modeling efforts within the Cape Fear River Basin, and shall be consistent with a
monitoring plan developed jointly by the Division and affected stakeholders.

Permit NC0047597
A. (6) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or
subsequent versions. The tests will be performed during the months of January, April, July, and October. Effluent
sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit
limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as
described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998)
or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that does
have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection
methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic
Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the
pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the
permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the
facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No
Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the
address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include
alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an
invalid test and will require immediate follow-up testing to be completed no later than the last day of the month
following the month of the initial monitoring.

BACKGROUND
The South Durham WRF has a permitted flow of 20.0 MGD. The current permit expires April
30, 2006. The Permittee submitted Standard Form 2A on September 9, 2005 to request renewal
of the permit. South Durham has a full pretreatment program with the Division of Water
Quality's Pretreatment Unit and will continue to implement this program in the new permit term.
Permitted industrial flow is 0.53 MGD and average industrial flow is 0.29 MGD. The facility has
not requested any changes to the permit, other than the removal of the fluoride limit.
Instream Monitoring, Verification of Existing Conditions and DMR Data Review
This facility discharges to an unnamed tributary to New Hope Creek in sub basin 03-06-05 of the
Cape Fear River Basin. The receiving stream is classified WS-IV NSW waters, and is listed as
impaired on the 2006-303(d) list due to impaired biological integrity and turbidity. DMR data
from January 2004 through December 2005 were reviewed. Data are summarized below.

NC0047597 Data Summary (January 2004-December 2005)
A review of the metals (from both the DMRs and Pretreatment data) and toxicants was also
performed. These are discussed in the Reasonable Potential Analysis section. Permittee is a
member of the Upper Cape Fear River Basin Association, therefore does not collect separate
instream data.

Correspondence
The Raleigh Regional Office (RRO) last conducted a Compliance Evaluation Inspection in
August 2004 and found the facility to be in compliance. The South Durham WRF has received
no Notices of Violation (NOVs) or Enforcements Actions over the course of this permit term.
The facility has also been in compliance with its toxicity limit during this permit term.
South Durham is a member of the Upper Cape Fear River Coalition. Recommend continuation of
waiver of instream monitoring for dissolved oxygen and temperature as long as this membership
continues.
PERMITTING STRATEGY
Waste Load Allocation (WLA)
The Division prepared the last WLA for the previous permit renewal. The previous and current
effluent limits were based on guidelines and water quality standards. The Division has judged
previous parameters and limits to be appropriate for renewal with some exceptions. Changes to
toxicant monitoring are discussed in the Reasonable Potential Analysis section. Weekly average
ammonia limits based on a 3:1 ratio with the monthly average will be implemented in this
permit. This is a new statewide policy that resulted from EPA requirements. The resulting
summer weekly average limit will be 3.0 mg/L and the winter limit will be 6.0 mg/L.
In addition, an annual pollutant scan will be added such that the Permittee can collect the
necessary data required by EPA Form 2A throughout the permit term. This condition is now
standard on all major municipal permits in North Carolina.
Reasonable Potential Analysis (RPA)
The Division conducted EPA -recommended analyses to determine the reasonable potential for
toxicants to be discharged by this facility, based on DMR and pretreatment data from January
2002-January 2006. Calculations included parameters listed in the previous permit and pre-
treatment documents to include: cadmium, fluoride, mercury, molybdenum, copper, and zinc.
Results suggest no reasonable potential for the facility to discharge cadmium, fluoride,
molybdenum, or copper. Therefore, the fluoride limit will be removed and the monitoring
reduced to 2/month. Zinc showed reasonable potential, but is an action level standard. Since the
facility has not been experiencing toxicity, monitoring will be continued with no limit. Mercury
has an allowable concentration of 12 ng/L. In the initial analysis, only nine data points using
Method 1631 were available; the highest actual concentration was 5.1 ng/l and the maximum
predicted concentration was 14.6 ng/L. At the Division's request, the permittee collected five
additional samples, all of which measured below 2 ng/1. The additional data lowered the
maximum predicted effluent concentration to 12.5 ng/1. Due to the small data set, the recent
implementation of the new low-level method change, the lack of impairment for mercury in the
receiving waters, and the highest actual concentration of less than half the allowable, the
Division recommends that mercury continue to be monitored in the LTMP without being limited
in the permit at this time.
Toxicity Testing
Current Requirement: Chronic toxicity P/F @ 90%; January, April, July, October. The facility
has consistently passed the toxicity test since 2001.
Recommended requirement: Chronic toxicity P/F @ 90%; January, April, July, October.
Cape Fear Nutrient Permitting Strategy
For the 2006 permit renewal cycle the Division developed a permitting strategy to address
nutrient concerns in the Cape Fear River Basin. This strategy is being applied at permit renewal
to existing discharges on the basin. The strategy calls for additional nutrient monitoring and
Fact Sheet
NPDES NC0047597 Renewal

reporting to support the efforts of the Modeling and TMDL Unit in developing special studies
and TMDL projects. Dischargers in the Jordan Lake watershed will monitor TN and TP 3 times
per week, report nitrogen species, and report TN and TP as both concentration and mass loads.
The permit also includes a re -opener special condition. In the event that the Environmental
Management Commission adopts a nutrient management strategy or the EPA approves a TMDL
in the coming permit term, the condition allows the Division to re -open affected permits to set
nutrient limits and related conditions accordingly.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the following will be incorporated into the permit:
• New weekly average ammonia limits (both summer and winter)
• Annual pollutant scan included
• Elimination of the fluoride limit and reduction of the monitoring frequency to 2/month
• Nutrient monitoring and reporting as per new Cape Fear Nutrient Strategy.

This letter is in response to the draft permit for the South Durham Water Reclamation
Facility, NC0047597, received on June 12, 2006. The following comments address
concerns by the City of Durham:
1. There appears to be a typographical error in the Effluent Limitations and
Monitoring Requirement sheet as the frequency for Fluoride monitoring does
not match the monthly monitoring as proposed in the cover letter.
The City is requesting the Fluoride monitoring requirement be removed based
on over 10 years of effluent fluoride analyses with all concentrations well
below the 1.8 mg/1 limit, see attachment. Effluent Fluoride samples will still
be analyzed quarterly as part of the Long Term Monitoring Plan.
2. The Division of Water Quality is recommending three times per week
monitoring for Total Phosphorous and Total Nitrogen which includes Total
Kjeldahl Nitrogen, Nitrite Nitrogen and Nitrate Nitrogen. The cover letter
states the additional data is needed to support the modeling efforts for special
studies and TMDL projects.
The City is requesting the monitoring frequency remain weekly for both
parameters. The South Durham Water Reclamation Facility has been
operating biological nutrient removal processes for over 10 years.

Ms. Teresa Rodriguez
July 10, 2006
Data has been submitted since 1997 with weekly results for both Total
Nitrogen and Total Phosphorous. In 1995 and 1996 Total Nitrogen was
analyzed monthly and Total Phosphorous weekly. Given the amount of data
already collected, it would not appear additional three times per week
sampling would provide significant benefit that would justify the cost of the
additional analyses. Especially, since Jordan Lake will not be sampled at the
same frequency to provide a direct correlation. In addition, it appears that no
other dischargers to Nutrient Sensitive Waters have a three times per week
testing requirement.
We appreciate the opportunity to comment on the draft permit and would welcome
further discussion if necessary. If you need any additional information, please contact me
at 919-560-4386.

One was for Huffman Finishing NC0025135. This is what I had in the fact
sheet:
"Although the analysis showed a maximum predicted concentration above
the allowable concentration, it is important to note that all three
actual detections were below the calculated allowable concentration. In
this case it appears that the large number of non -detects was a
contributing factor in yielding a high multiplication factor (7.4).
Based on this analysis, antimony will continue to be monitored quarterly
in the permit."
If you check the file you'll see some email correspondence between me
and Marshall. I know there were some other examples but this is the
first one I've put my hand on.

fluoride is what is put in at the Water Treatment Plant there is no way we would ever

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 of fish consumption advice that applies to the entire
basin. In the water supply category, all WS classified waters (10,902.4 acres and 124.9 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 53.6 stream miles (28.5 percent) and 8,288.8 freshwater acres (76 percent) monitored
during this assessment period in the aquatic life category. There were 21.1 miles (11.2 percent)
and 8,288.8 acres (76 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 # 16-41-1-(14)]
New Hope River Arm [AU # 16-41-(0.5) and (3.5)a]
Morgan Creek Arm [AU # 16-41-2-(9.5)] (Subbasin 03-06-06)
Haw River Arm [AU # 16-(37.3) and (37.5)] (Subbasin 03-06-04)
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
Chapter 5 — Cape Fear River Subbasin 03-06-05 55

acres) are Not Rated for aquatic life. Data to assess recreation use support were not collected in
the reservoir.
2005 Recommendations
Refer to Chapter 36 for complete discussions of the Jordan NSW strategy, TMDLs, modeling,
monitoring, HB515 and SB1366. 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 el
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 BB324.
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 [16-41-1-(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.
New Hope Creek [16-41-1-(11.5)c] from I-40 to SR 1107 (4 miles.) is Impaired for aquatic life•
because of a Fair benthic community rating at site BB238. The riparian zone was intact at site
BB238, 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
sampling. There are many single family NPDES permitted discharges in this watershed that may
contribute oxygen -consuming wastes as well as bacteria and nutrients.
Chapter 5 — Cape Fear River Subbasin 03-06-05 56

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 to 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, 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. In 1999, NCEEP (Chapter 34) received a $582,500 CWMTF grant to stabilize and
restore 450 linear feet of Sandy Creek [ 16-41-1-11 ] 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.
The NCEEP completed 3,000 linear feet of stream enhancement in the Sandy Creek watershed.
5.3.3 Northeast Creek [AU # 16-41-1-17-(0.7)a, bl and b2]
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)b l ] 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. 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).

Influent lines to the South Durham Water Reclamation Facility

South Durham Water Reclamation Facility
The South Durham Water Reclamation Facility was originally built in 1984 as a 10 MGD
activated sludge facility. In 1990, the facility was upgraded to include processes for
chemical and biological phosphorous removal in addition to belt filter presses for sludge
dewatering. Traveling bridge effluent filters were also added to improve effluent quality.
In 1994, the facility was expanded to 20 MGD and upgraded to include biological
nutrient removal, gravity belt thickeners, ultraviolet light disinfection, odor scrubbing and
a computer control system. With the addition of two anaerobic digesters in 1998, all
sludges, primary and waste activated, are digested anaerobically then land applied as a
Class B product. The City contracts with Synagro Southeast to land apply biosolids to
privately owned farm land that is permitted in the City of Durham's name.
The South Durham facility is home to the Water and Wastewater Laboratory. This state -
certified laboratory runs the majority of analyses for two (2) water plants, two (2)
wastewater plants, the Industrial Pretreatment Program and the Storm Water Program.
At present no other construction is planned for the facility.
Flow moves through the following processes:
Preliminary Treatment: Barscreens and Grit Chambers
Primary Treatment: Primary Clarifiers
Secondary Treatment: 5 stage Bardenpho Activated Sludge and Final
Clarification
Tertiary Treatment: Chemical Addition, if needed, and Effluent
Filtration
Disinfection: Ultraviolet Light
Sludge Management Plan
Sludge is anaerobically digested and dewatered using belt filter presses or
sand drying beds. Dewatered biosolids are stored on a sludge storage pad and
land applied as a Class B product on permitted sites under Land Application Permit,
WQ0003504. The City contracts with Synagro for the land application of all solids
produced at the facility.
Attached is a list and specifications for all equipment and tankage at the facility.

Sewer Rehabilitation Program
Durham first established a Sewer Rehabilitation Program in 1986. By the mid-1990s the
program was fully implemented. The major areas of the program are:
Data Management - The City has 41 permanent flow monitors in its collection system.
These monitors are checked daily for indications of line failures or Sewer System
Overflows (SSOs). The flow data helps direct the efforts of the program. The City
maintains a Rodding Database (since 1990) of all the lines are rodded and cleaned. This
is used to identify repeat blockages that need to be addressed with preventative
maintenance.
Outfall Maintenance — The City actively maintains its sewer outfalls to ensure
accessibility for both routine maintenance and emergencies. The City maintains two
mowing crews. In addition the City contracts out over 90 miles of mowing annually.
Cleaning — The City cleans between 500,000 - 600,000 feet of sewer lines on an annual
basis using City staff. The new state collection system permit requires the City to clean
10% of the system on an annual basis. An additional 150,000 feet will be cleaned using
private contractors to meet the new permit requirements.
Inspections — The City inspects approximately 100,000 feet of sewer line on an annual
basis using Closed Circuit TV (CCTV). In fiscal year 2005 - 2006 the City plans to
increase the annual CCTV inspection to 250,000 feet. CCTV inspections identify lines
that need to be rehabilitated or replaced. The City also performs biannual inspections of
its high priority lines. In addition, the City conducts manhole inspections.
Preventive Maintenance — By analyzing the rodding database, the City has identified
sewer lines that have repeat blockages due to roots or grease. The City has contracted
root control contracts in previous years as areas were identified; a contract is planned for
this fiscal year. The City anticipates having a grease control contract underway this year
as well.
Rehabilitation/Replacement - CCTV inspection identifies lines that need to be
rehabilitated or replaced. These lines are prioritized on a point repair/replacement list
that is updated monthly. City crews perform work on the higher priority lines. The City
contracts out between $750,000 - $1,500,000 annually for point repairs and line
replacement.
