Skvarla, III Governor Secretary November 26, 2014 Mr. Garland S. Grant I11,Water Superintendent Town of Belhaven PO Box 220 Belhaven,North Carolina 27810 Subject: Final NPDES permit Permit NCO086584 Belhaven WTP Beaufort County Class I Facility Dear Mr. Grant: DivisionP ersonnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES 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 October 15, 2007 (or as subsequently amended). The final permit contains the following changes from your draft permit: • Quarterly monitoring for Total Iron was added to the Effluent and Monitoring Requirements. This parameter was inadvertently omitted from your draft permit. Total Iron showed reasonable potential to exceed the water quality standard. • Monitoring frequency for Total Nitrogen and Total Phosphorus was modified to quarterly to conform to 15A NCAC 2B. The final permit contains the following changes from your previous permit: • As a result of a reasonable potential analysis monitoring for fluoride, copper and nickel were eliminated from the effluent monitoring requirements. • Established the downstream instream sampling location as 100 feet downstream from the discharge.The current permit did not specify the locations where the instream samples should be collected. The upstream sampling requirement was eliminated from the permit as 1617 Mail Service Center,Ralegh,North Carolina 27699-1617 Location:512 N.Salisbury St,Raleigh,North Carolina 27604 Phone:919-807-63001 FAX:919-807-6492 Internet:wwwmwaterauality.om One NorthCarolina An Equal Opportunity 1 Affirmative Action Employer Naturally Mr. Garland S.Grant November 26,2014 Page 2 of 3 there is no flow upstream of the discharge.As a member of the Tar Pamlico Monitoring Coalition instream sampling requirements are waived. • The whole effluent toxicity (WET) test in your permit was modified to a chronic 90%test using ceriodaphnia dubia.During the last permit renewal the stream classification was corrected to C-NSW,Sw but the WET test was not modified accordingly.As per WET guidance a chronic test at 90%is implemented for discharges to freshwater streams when the IWC is 100%. • To address the Environmental Protection Agency's (EPA's) pending requirement for you to provide electronically-submitted Discharge Monitoring Reports (eDMRs) a footnote to Special Condition A.(1) and Special Condition A.(3) were added to the permit.

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. A(3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS Proposed federal regulations require electronic submittal of all discharge monitoring reports(DNIlts)and specify that, if a state does not establish a system to receive such submittals,then permittees must submit DMRs electronically to the Environmental Protection Agency(EPA). The Division anticipates that these regulations will be adopted and is beginning implementation in late 2013.

From: Hollenkamp, Carol Sent: Friday, September 19, 2014 1:02 PM To: Meadows, Susan; Moore, Cindy Subject: RE: WET test for Belhaven WTP - NCO086584 I agree, it looks like it was just classified wrong in 1999. Teresa said their discharge occurred in a location that is officially classified as freshwater. They should get the acute fathead at 90%. I'm assuming they have an acute test since they are discharging to a series of freshwater canals that they don't have an IWC,or that the IWC is less than 0.25%. From: Meadows, Susan Sent: Friday, September 19, 2014 12:56 PM To: Moore, Cindy Cc: Hollenkamp, Carol Subject: RE: WET test for Belhaven WTP - NCO086584 So my understanding is when the permit was issued in 1999, it was mis-identified as saltwater. However it is upstream of where it turns brackish and becomes saltwater. So, it should have been identified as freshwater. This was not caught&/or changed until 2011.

From: Rodriguez,Teresa Sent: Friday, September 19, 2014 12:18 PM To: Moore, Cindy; Meadows, Susan Subject: WET test for Belhaven WTP - NCO086584 Cindy&Susi, I am renewing this permit and noticed a discrepancy in the water classification and the WET test. When this permit was issued in 1999 the creek was identified as class SC and all limits set accordingly.The WET test was an acute mysid shrimp.Then in 2011 Jim Mckay corrected the classification to C.The discharge location is a systems of canals that eventually discharge to Pantego Creek just before the classification changes from C to SC,so technically the discharge is to an unnamed tributary and class C. The 2011 permit was issued with the same acute test but I didn't find any documentation in regards to looking at the acute test and changing it to a freshwater species, I don't know if it was considered or if it wasn't addressed.What would you recommend in this case?
