Rockfish Creek WRF
NPDES Permit No. NC0050105
Dear Mrs. Sprinkle:
DENR FRO
JUN 2 1 20fl
DMZ
Enclosed are an original and two copies of the NPDES permit renewal application (EPA Form 2A), a brief
narrative found in this cover letter explaining the biosolids management plan, a request for additional
permit limits at 28 MGD and reduced monitoring for the Rockfish Creek Water Reclamation Facility
(WRF) located in Cumberland County. The current NPDES permit, NC0050105, was issued in March 1,
2007 and expires at midnight on October 31, 2011.
The Rockfish Creek biosolids management process scheme treats all aerobically digested waste activated
sludge through five 1.2 MG coarse bubble digesters. A minimum of 40 days per digester allows for proper
stabilization and meets all EPA 503 Class B requirements for Pathogen and Vector Attraction Reduction.
After the aerobic digestion process, the biosolids are thickened and placed in three 0.7 MG aerated storage
tanks. Beneficial re -use of these thickened biosolids are utilized through a liquid land application program
with participating agricultural farms in Cumberland and surrounding counties.
A Phase III expansion of the Rockfish Creek WRF to 28 MGD is being planned. This project, which may
include a new aeration basin, clarifier, effluent filters, aerobic digester and biosolids storage tanks, could be
in the early stages of construction prior to the end of this next five-year permit cycle. Therefore, PWC is
requesting that permit limits at 28 MGD remain in this next permit renewal. PWC has already submitted an
Environmental Assessment (EA) and received a Finding of No Significant Impact to expand the facility
beyond the future 24 MGD permitted flow.
As part of this permits renewal, PWC would like to request reduced effluent monitoring. PWC believes
that five days per week sampling for CBOD, TSS, NH3-N, and Fecal Coliform is unnecessary to fully and
accurately characterize the effluent at the Rockfish Creek POTW. PWC also believes quarterly bioassay
testing is unnecessary. This request is based on the letter submitted to NC DWQ on February 22, 2011
from the NC Water Quality Association regarding reduction of monitoring frequency.
Analysis of the data collected over this permit cycle (March 1, 2007 through April 30, 2011) indicates a
consistent high quality discharge at this facility. During this period, the Rockfish Creek POTW
experienced two permit violations of its NPDES Permit. A CBOD violation occurred on July 8, 2008 at a
value of 83.3, which resulted in a weekly violation of the CBOD limit. This violation was due to a
malfunctioning sodium bisulfite feed system and was corrected that day. The other violation was a failure
of Aquatic Toxicity on April 7, 2008. These violations were isolated incidents and PWC feels the data
supports a reduction in monitoring. Comparison of the data to weekly limits yields the following results.

The Rockfish Creek WRF has been performing quarterly Aquatic Toxicity testing for many years without
any indication of toxicity problems. During this permit cycle the Rockfish Creek WRF performed 22
Aquatic Toxicity assays with one failure in April 2008. After the failure in April 2008, PWC ran additional
Aquatic Toxicity tests, accompanied by Priority Pollutant Scans to try and determine the cause of the
failure. The result of the PPS's revealed no pollutants of concern and there were no other Aquatic Toxicity
failures. It is our opinion that this failure was an anomaly and we feel the data supports this conclusion.
As you can see the Rockfish Creek WRF's discharge is well below the permit limits for CBOD, NH3-N,
TSS, fecal coliform, and has demonstrated a history of compliance with the Aquatic Toxicity testing
requirement. The data indicates that there is no significant difference in 5 day per week sampling versus 1
day per week sampling and no significant difference in which day of the week the samples are collected.
The Aquatic Toxicity data supports once per year sampling.

A reduction in routine monitoring would save money and staff resources. PWC estimates a savings of up
to $11,930 per year, or $59,650 per permit cycle. PWC herebyrequests a reduction in monitoring
frequency for CBOD, TSS, and NH3-N to weekly and a reduction for fecal coliform monitoring frequency
to twice a week. In addition, we request a reduction in Aquatic Toxicity testing to once per year.
If you have any further questions, please feel free to contact me at (at [phone].

The Rockfish Creek facility is permitted to process 21 million gallons per day
(MGD) of wastewater. The processes consist of an influent pump station,
mechanical bar screens, grit removal, activated sludge system with nitrification,
secondary clarification, filtration, disinfection and dechlorination using
hypochlorite and sodium bisulfite. Biosolids generated by these processes are
stabilized through aerobic digestion. The Rockfish Creek biosolids are
thickened and recycled through land application as fertilizer and soil
conditioners.

-. PART E. TOXICITY TESTING DATA. - E
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to
