Goodrich NCDENR/DQW NPDES Unit 1617 MailService Center Raleigh, NC 27699-1617 Dear Mr. Goodrich (VtOV ► 0J i✓ - s A300 June 26, 2003 Subject: Eagle Road WWTP' Gaston County NC0006033 The Town of Cramerton requests a permit modification to reduce the fecal cwliform sampling and analysis at the up and down stream stations from three times per week to once per week during the summer months, (April 1 — October31). Our budget restraints have caused us to limit our wastewater laboratory staff to one technician. Please advise in this matter If you have questions, call 704-825-7499.

Subject: follow-up on modification request From: Charles Weaver <charles.weaver @ ncmail.net> Date: Fri, 10 Oct 2003 09:32:58 -0400 To: Toya Fields <Toya.Fields@ncmail.net> Toya, there's a modification request from the Town of Cramerton on my desk. I didn't get it resolved and I'm hoping you can. The Town requested a reduction in fecal monitoring instream. They offered no data in support of the request. I received a call from the Town before I could return the request. I told the man who called that "we don't wanna" isn't sufficient reason for us to reduce monitoring. He countered that we had allowed this modification for the City of Mount Holly, a nearby WWTP in the same watershed. I told him I was returning the request, but that Cramerton could re -submit it with supporting data. If the data showed that the instream fecal concentrations weren't affected by the effluent, we might reduce the monitoring. Unfortunately, the request got buried and I never returned it. Here's what I need you to do: 1. Research the change in fecal monitoring for the Mount Holly WWTP (NC0021156). See if you can determine why instream fecal monitoring was reduced. 2. Contact the Town of Cramerton and explain the mix-up on my part. Ask if they want to submit data in support of the original request, and have them send it to you if they do. 3. If they don't want to pursue this, write a return letter and send back the original request. 4. If they submit the data, evaluate it and see if there is cause to reduce the monitoring. Mark and/or Susan can help you with this. 5. Respond to the data submission with either a permit modification or a letter saying why the monitoring must remain as -is. Thanks for helping with this.

Wilson, Environmental Engineer NPDES Unit Subject: Guidance Regarding Conductivity and Fecal Coliform Monitoring INSTREAM CONDUCTIVITY AND FECAL COLIFORM MONITORING GUIDANCE Fecal coliform monitoring: Instream monitoring for fecal coliform may be removed from municipal or domestic wastewater permits (major or minor), unless the water body is impaired due to coliform or is a Class B waterbody. Conductivity monitoring: Instream monitoring for conductivity may be removed from all 1000/6 domestic wastewater permits. Instream conductivity monitoring must remain for industrial discharges and domestic discharges that have a pretreatment program.
