Subject: NPDES #NC0036269 Renewal Application
Rocky River Regional Wastewater Treatment Plant (RRRWWTP)
Enclosed is the subject permit renewal application, topographic map showing the point of discharge, plant process
schematic and supporting documentation for required toxicity results.
Since the previous permit cycle, RRRWWTP has triggered the 26.5 MGD permit tier and is currently abiding by those
limits. WSACC requests that NCDENR evaluate this trigger during the renewal process based on the average daily 3-
year flow rate of 16.69 MGD being so much lower than the 21.6 MGD trigger and that the exceedance was only 21.9
MGD occurring during a record -breaking rainfall event.
Thank you for your consideration of this matter. If you have any questions or comments, please feel free to contact
either myself at 704.788.4164, ext. 111 or John Ritchie, Wastewater Operations Manager/ORC at 704.788.4164, ext.

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
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 EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.

Water & Sewer Authority of Cabarrus County
Rocky River Regional Wastewater Treatment Plant
MERCURY MINIMIZATION PLAN
May 1, 2014
SECTION I - PURPOSE
The purpose of this Mercury Minimization Plan ("MMP") is to describe best management practices
through which the Rocky River Regional Wastewater Treatment Plant (RRRWWTP) will seek to reduce
the amount of mercury discharged into its system and, ultimately, to the environment. The MMP
compiles mercury reduction -related efforts to -date and potential future action items. It is designed to be a
working document to help guide the Water & Sewer Authority of Cabanus County (WSACC) in its
efforts to control mercury loadings discharged into its Publicly -Owned Treatment Works (POTW) by
users of the sewer system. Such a reduction in loadings to the sewer system should translate to a
reduction in the amount of mercury which is discharged from the treatment plant. The management
practices summarized below may also help control some of the mercury reaching our storm sewer system
as well.
SECTION II — FACILITY DESCRIPTION
WSACC operates a publicly owned treatment works (POTW), including a collection system and
wastewater treatment plant (WWTP), which serves the cities of Concord and Kannapolis, towns of
Harrisburg and Mt. Pleasant, and Cabarrus County, North Carolina.
RRRWWTP's treatment process consists of a permitted 24 MGD facility. The plant design has units of
process to remove/reduce suspended, colloidal, and dissolved solids, and the reduction of organic
materials via biological oxidation. Ammonia nitrogen is reduced and converted to nitrates by biological
oxidation. No tertiary treatment at present.
Wastewater enters at MPS (barscreens), then is pumped to Headworks. This flow is combined with
additional flows at the front of Headworks. After passing through barscreens, the wastewater flow enters
vortex grit chambers for grit removal. From the grit system, wastewater flows to Box 10, where it is split
between the 4 primary clarifiers. Depending on flow rate, the typical detention time in the primary
clarifiers is 7-8 hours (volume capacity is 1.2 MG each). The supernatant flows thru V notch weirs, then
to the aeration basins (mechanical mixing plus 02 blanket). The settled solids of the primaries are
pumped to the gravity thickeners. Primary clarifiers remove about 95%of the TSS.
The wastewater entering the aeration basins mixes with high purity oxygen and existing micro-organisms
allowing for the removal of organic material such as BOD and COD. From the aeration basins the
wastewater flows into the secondary clarifiers for additional settling. The supernatant flows thru the V
notch weirs and goes on to disinfection. A percentage of the solids removed from the bottom of the
secondary's is recirculated to the head of the aeration basin to ensure the predominance of the most
effective micro-organisms for BOD and COD removal (returned activated sludge). Determined by lab
results for MLSS, we must remove some of those micro-organisms from the process all together
(wasting). The Waste Activated Sludge (WAS) is taken out at the same point as the RAS but is not
introduced back into the treatment process. Instead it is pumped to the gravity thickeners, or back to the
MPS.
The supernatant from the Secondary Clarifiers flows to flume 3 (for effluent flow monitoring, plus
sodium hypochlorite addition for disinfection). After hypochlorite addition, the flow enters a chlorine
11Page

contact basin for a minimum 30 minutes to enable proper disinfection. From the contact basin, the
wastewater is treated with sodium bisulfite for residual chlorine depletion to meet permit limits for
discharge. The wastewater then passes through sample box 8 to final discharge to the Rocky River.
The solids removed from the primary clarifiers are pumped to the gravity thickeners where the water
separates and flows over the weirs. The solids are then pumped off the bottom, into the dewatering
building, then fed to centrifuges, with polymer addition, to form a "Cake" which is then pumped to the
furnace for incineration. Ash .from the incinerated solids is pulled off the bottom hearth of the furnace,
mixed with non -potable carry water, and pumped to the ash pond.
Most municipal treatment plants are not designed to remove mercury and it is exceedingly expensive to
do so to very low levels. Incidental mercury removal occurs through typical municipal treatment with
trace levels of mercury (and other metals) ending up in solids removed from the raw wastewater.
Mercury is not used in the treatment processes at the WWTP. Mercury may be introduced into the sewer
system through a variety of sources, such as from industrial users, laboratories, and other businesses.
Residual deposits of mercury are also possible in the sewer system from historic practices. Finally, trace
amounts from household products and atmospheric deposition (both wet and dry) contribute to sewer
system mercury loadings.
While there is typically some mercury contributed to public sewer systems statewide, it is usually in
minute quantities and comprises a tiny portion of the already insignificant statewide loading for all point
sources just two percent of the annual mercury loadings to all State waters.
WSACC has for years measured mercury levels at the treatment plant and strive for a zero discharge
SECTION III — PROGRAM PLAN
A. EVALUATION OF POTENTIAL NON -DOMESTIC SOURCES CONTRIBUTING
MERCURY TO THE POTW
Within 24 months from the NPDES required 180-day period for development of an MMP, WSACC will
evaluate available information to assess the potential for non -domestic users of the sewer system to
contribute mercury to the system. The information to be reviewed may include: (1) POTW influent and
effluent mercury data and trends; (2) industrial user permits and associated mercury monitoring data; (3)
Toxics Release Inventory (TRI); (4) state hazardous site registry and the National Priority List relating to
mercury contamination; and (5) historical records of industrial sites which have contributed mercury
loadings to the sewer system.
WSACC will also survey and evaluate the following common sources of mercury in its service area: (1)
dentist offices; (2) hospitals; (3) laboratories; (4) auto recyclers; and (5) other potential sources of
mercury based on existing information.
WSACC will request that industrial users review mercury concentrations in high -volume process
chemicals and demonstrate that the mercury concentrations are below industry average. WSACC will
request that alternative sources for chemicals be explored if the mercury levels are determined to be
significantly higher than would normally be expected.
2 1 P a g e

The evaluation of potential non -domestic sources of mercury to the sewer system will be updated every
five years, as warranted by prior sampling results and any additional new potentially significant sources to
the system.
B. ADDITIONAL CONTROL MEASURES
This MMP identifies reasonable and cost-effective control measures to minimize mercury being
discharged into the POTW. Below is a listing of initial BMPs for this POTW.
Pollution Prevention
Substances used at the WWTP will be evaluated to determine if they contain mercury or mercury -based
compounds. Any such chemicals will be evaluated for substitution with non -mercury -containing
substances.
Housekeeping, Spill Control and Collection. and Education
WSACC will develop procedures to minimize the possibility of any spill or release at the WWTP
involving mercury containing substances. WSACC will add mercury identification and proper disposal to
ongoing and future operator training procedures.
Public Outreach
WSACC will make available educational information regarding sources of household mercury and
appropriate use/disposal practices. This information may be posted on WSACC's website. The
availability of this information will be highlighted in periodic reports and/or outreach to WSACC's
customers. WSACC will work with the Cabarrus County Household Hazardous Waste Recycling
Program to increase public awareness regarding community collection points for mercury -containing
products from residents/customers for proper disposal. Periodic reminders of such collection programs
will be provided as part of WSACC's ongoing public outreach.
Laboratory Practice
WSACC operates a laboratory for purposes of complying with state and federal monitoring and sampling
requirements. The laboratory is a potential source of small quantities of mercury -containing compounds.
Laboratory employees will be trained in the proper handling and disposal of these materials. The
laboratories have also replaced mercury thermometers with non -mercury thermometers, whenever
practical.
Also, WSACC currently recycles all of the COD vials used in the laboratory.
C. TRACKING AND MONITORING
In order to assess the implementation of the control measures, WSACC proposes to undertake the
following evaluations beginning after the first full year that this MMP is implemented:
1. Survey annually at least ten percent (10%) of any non -domestic users identified as
possible significant sources of mercury to the POTW;
2. Track the implementation of the programs outlined above;
3. Monitor influent mercury at least annually. Require significant non -domestic sources of
mercury to monitor periodically, as warranted; and
4. Measure effluent mercury as required by the NPDES permit.
3 1 P a g e

These efforts will allow WSACC to establish a baseline of influent and effluent mercury levels to assist in
identifying any trends in mercury contributions from domestic and non -domestic users of the sewer
system. This baseline will be tracked annually.
SECTION IV — RUPLEMENTATION OF CONTROL MEASURES
WSACC's pretreatment program has implemented a local limit for mercury. WSACC's pretreatment
program also (1) monitors the significant industrial users for mercury and works with them, if needed, in
reducing their mercury load to the POTW; (2) monitors uncontrollable sources to identify potential
mercury sources; (3) in the past, has met with the local dental association to discuss mercury (amalgam)
removal and the importance of minimizing mercury discharges to the POTW.
WSACC will implement the control measures summarized in Section III over the permit term and will
update this MMP as warranted.
SECTION V - REPORTING
A summary of the MMP activities will be submitted as part of the NPDES permit renewal process.
