NOTES
• In the facilities application (February 2022), they noted that "For the past few months this discharge
has been recycling to our onsite raw water reservoir. This has working well so far, but we anticipate
need to discharge again when warmer weather is upon us, and distribution demand picks up."
Their last discharge was in 2021. Flow and parameter data has been utilized up to the application
date rather than the most recent data as there isn't any from mid-2021 to present.
• James Bennett, the contact listed on the application, no longer works for this facility. Julius Patrick,
the MCRWASA Chairman, is the new designated contact.
FACILITY SUMMARY
The Martin County WTP utilizes conventional technology [coagulation, flocculation, sedimentation, and
filtration] with a design potable flow rate of 2 MGD that draws raw water from the Roanoke River. The
maximum, monthly average wastewater discharge was 0.285 MGD in the last permit cycle. The discharge
produced from the treatment plant is from media filter backwash and sedimentation basins.
The existing treatment components at the water treatment plant are the following:
• alum sludge decant from super pulsator clarifier
• a 529,300-gallon sludge storage tank for gravity thickening and decanting
• a 529,300-gallon filter backwash storage take for equalization, solids settling and decanting
• de -chlorination
Chemical usage consists of:
Fact Sheet for Permit Renewal
May 2024 - NPDES Permit NCO089435 - Page 1

• Alum/Aluminum sulfate [primary coagulant]
• Sodium hypochlorite [disinfection]
• Ammonium sulfate [secondary disinfection]
• Sodium hydroxide [pH adjustment]
• Polymer [flocculation]
• Sodium permanganate [oxidizer/ precipitation]
• Powdered activated carbon (PAC) [adsorption of organic for taste & odor]
• Zinc orthophosphate [corrosion inhibitor]
• Copper sulfate [biocide for controlling algae in holding basin]
• Aluminum hydroxide
• Calcium thiosulfate
RENEWAL SUMMARY
This renewal contains the following changes:
• Section A. (3) has been updated regarding electronic submission of effluent data. Federal
regulations require electronic submittal of all discharge monitoring reports (DMRs).
• Whole Effluent Testing has been updated to a pass/fail limit per the Division's current strategy for
conventional water treatment plants. See section A. (1) and A. (2)
• The Supplement to Cover Sheet has been updated with the with new max monthly average.
• The facility grade has been added to Section A. (1).
• The daily total residual chlorine limit in Section A. (1) has been changed to 17 µg/L as reflected in
the IWC spread sheet. The Division shall consider all effluent TRC values reported below 50 µg/L
to be in compliance with the permit. However, the Permittee shall continue to record and submit all
values reported by a North Carolina certified laboratory (including field certified), even if these
values fall below 50 µg/L.
COMPLIANCE HISTORY
No compliance concerns in the last permit cycle; 2 NODs from 2021 and 2022.
NCG59 GENERAL PERMIT ELIGIBILITY (FOR CONVENTIONAL & GREENSAND ONLY)
The Martin County WTP is not eligible for the general permit because there is not enough data to make this
determination. The facility needs a greater than 75% passing rate for twelve (12) quarters of active
discharges and passing results for the most recent four (4) consecutive quarters. [See attached Whole
Effluent Toxicity (WET) Testing below].
• Conclusion: Ineligible for NCG59 General Permit.
WHOLE EFFLUENT TOXICITY (WET) TESTING
In accordance with current strategy, quarterly WET testing is required in this permit as Freshwater 7 day
Chronic [TGP3B] Pass/Fail Limit with Ceriodaphnia dubia at an effluent concentration of 90%.
The facility passed all (10) tests from March 2019-June 2021. They have not discharged since, so there is
not WET data past this last test.
REASONABLE POTENTIAL ANALYSIS
A reasonable potential analysis (RPA) was performed for a discharger going to a freshwater stream. A flow
(Qw) of 0.285 MGD was used based on the maximum, monthly average flow between February 2019 and
October 2022.
Based on this analysis, the following permitting actions are proposed for this permit:

• Zinc — no reasonable potential to exceed water quality standards; maintaining quarterly monitoring
• Copper — no reasonable potential to exceed water quality standards; maintaining quarterly
monitoring
