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 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
complete.

SLUDGE MANAGEMENT PLAN
The Town of Mayodan WWTP thickens sludge in one of two gravity thickeners and then it is
digested in an aerobic digester with the capacity of 0.4 MGD. The stabilized sludge is then land
applied either as a liquid directly from the digester or it may be dewatered on one of the 10 sand
drying beds and then land applied. The Land Application Permit(WQ0002672),permits a total of
197.6 acres.

Present Operating Status
The Town of Mayodan Wastewater Treatment Plant is a 3.0 MGD design capacity facility. The
facility treats a combination of domestic and commercial wastewaters.The current treatment scheme
includes a mechanical bar screen,grit removal system,activated sludge and secondary clarification.
The treated effluent is disinfected by chlorination followed by a dechlorination through the use of
Sulfur Dioxide.Following is a schematic of the existing wastewater treatment plant.The volumetric
capacities are noted on the schematic.

Mercury Minimization Plan Summar

MERCURY MINIMIZATION PLAN SUMMARY
TOWN OF MAYODAN
NPDES Permit No. NC0021873
November, 2021

MERCURY MINIMIZATION PLAN (MMP) SUMMARY
TOWN OF MAYODAN
NPDES Permit No.NC0021873
BACKGROUND
The NPDES Permit issued to the Town of Mayodan required the development of a Mercury
Minimization Plan. The Plan was developed as best management practices to reduce the amount
of mercury discharged into the Town's sewer collection system. The Town of Mayodan
committed to evaluate available information to assess the potential for non-domestic users of the
sewer system to contribute mercury to the system.
SUMMARY OF MMP
EVALUATION OF POTENTIAL NON-DOMESTIC SOURCES CONTRIBUTING MERCURY
TO THE POTW
Information evaluated to determine the potential sources of mercury entering the Town's
sewer system included: (1) POTW influent and effluent mercury data; (2) industrial user
mercury monitoring data; (3) collection system monitoring at a primary residential site;
and(4) dental office survey. Mercury monitoring results are included in Attachment I.
POLLUTION PREVENTION
Substances used at the WWTP were evaluated to determine if they contain mercury or
mercury-based compounds. No substances were identified.
HOUSEKEEPING,SPILL CONTROL AND COLLECTION,AND EDUCATION
The Mayodan Wastewater Treatment Plant has procedures in place to minimize the
possibility of any spill or release at the WWTP involving mercury containing substances.
The Mayodan Wastewater Treatment Plant will continue to add mercury identification
and proper disposal to operator training procedures.
