Box 429 Newland, NC 28657 Subject: Permit Modification NPDES Permit NC0021857 Town of Newland WWTP Avery County Dear Mr. Hoilman: Division personnel have reviewed and approved your application for a permit modification received on June 4, 2009. You requested that NPDES Permit NC0021857, issued March 13, 2006, be modified to allow: 1. Monitoring frequencies for BOD, TSS, Ammonia and Fecal Coliform be changed from 3/VVeek to Weekly. 2. Monitoring frequncies will revert to 3/Week whenever flows reach 80% of 0.32 MGD. 3. Sampling to be changed from Flow -proportional to Time Composite sampling. Please note that the A. (1). Effluent Limitations and Monitoring requirements page now contains language stating, "Beginning on the effective date of this permit and lasting until annual average flows reach 80% of 0.32 MGD or permit expiration..." The Division agrees with this request and has modified the permit accordingly. We are forwarding you the modified A. (1) and A. (2). Effluent limitations and Monitoring requirement pages of your existing NPDES discharge permit. These modified pages reflect these new Sampling and Monitoring changes. You should replace your existing effluent pages from your current permit with these two pages. This permit modification 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). If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding. Please note that this permit is not transferable except after notice to the Division. The Division may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water Quality or permits requ ired by the Division of Land Resources, the Coastal Area Management Act or any other Federal or Local governmental permit that may be required. If you have any questions concerning this permit, please contact Bob Guerra at telephone number (919) 807-6387 or by email at bob.querra a(�ncdenr.gov. Sincerely, Coleen H.

One thing to keep in mind is the facility has "UV" for disinfection, so the TRC limit should only be there IF they use chlorine. So, I don't know how you would word that, unless you have specific language that goes in the footnotes. Thanks, Don Price.

From: Price, Don Sent: Monday, July 20, 2009 1:34 PM To: Guerra, Bob Cc: Edwards, Roger; Haynes, Keith Subject: Newland WWTP NPDES NC0021857, Avery County Bob, Per our phone conversation of July 20, 2009; the staff of ARO support the request of the Town of Newland regarding their request to have monitoring requirements reduced from 3x/week monitoring to weekly monitoring. This request is based upon their "Actual" flow to the WWTP and not the "Design" flow (Actual flow avgs. 0.130 MGD, Design flow is 0.600 MGD). Past deficiencies noted in previous Inspection reports have been addressed by facility staff, and the request should be granted. If you have questions or need additional information, please advise. Thanks, Don Price. 1 Guerra, Bob From: Price, Don Sent: Wednesday, July 01, 2009 10:12 AM To: Guerra, Bob Cc: Edwards, Roger; Haynes, Keith Subject: Newland WWTP NC0021857, Avery County, reduced monitoring Bob, Discussions with staff here in ARO, regarding the subject facility and their request to conduct reduced monitoring for BOD, TSS, Fecal Coliform, and Ammonia. ARO staff feel this should be allowed due the fact Newland WWTP averages about 130,000 -140,000 gals./day; their WWTP capacity is 600,000 gals./day . This gives a little over 4 days (96 hrs.) detention time in the facility. The 0500 monitoring and reporting regulations allow for reduced monitoring and approval of time based composite samples when facilities have 24 hrs. or greater detention time through the WWTP. Please allow Newland their request for reduced monitoring, except for field parameters of pH, DO, Temp. and TRC, and Time based composite sampling. If you have questions or need additional information, please let ARO know.

Documentation has been sent to Roger Edwards, Supervisor of the Asheville Regional Office. We are forwarding a copy of his letter along with ours. Thank you for your assistance in this matter.

Div. of Water Quality - SWP Asheville Regional Office 2090 U.S. Hwy 70 Swannanoa, N.C. 28778 Attn.: Roger Edwards, Supervisor-SWP Subject: Request for Monitoring and Sami.. ing variance for Newlanc VVWTP, NPDES Pe; r,lit No. NC0021857 Avery Count; Dear Mr. Edwards: As previously requested by the Town of Newland, we are seeking a variance from current sampling and monitoring requirements of our subject NPDES permit. As stated in NPDES Perrr.it NC0021857, Part II, Section A. Definitions; Composite Sample, #4 - constant .t me/constant volume!: a series of grab samples of equal volume collected over a 24-hour period at a constant time interval. This method may only be used in situations where effluent flow rales vary less than 15 %. The grah samples shall be taken at intervals of no greater than 20 minutes apart during any 2 4-hour period and must be of equal size and of no less than 100 milliliters. Use of this method requires prior approval by the Director. This is also indicated in: 15A NCAC 02B .0503 DEF+NITIONS (4) (d). We currently do not have the capabilities of taking flow -proportional samples and would respectively request we be allowed to take time composites. Flow data (charts) previously subrhitt reveal our flow does not vary over 15%. The outside markings are cf our influent and the inside mark;. gs are of the effluent. The wide discrepancy noted on the charts reflect the Ions; detention time in o , process and Inflow and Infiltration during rain events. Since the V',M/TP was upgraded to a 0.600 MGD Oxidation Ditch consisting of 2 - 0.300MGD trains, our flow charts have reflected Ihis wide range, and we only use ME' 0.300 side of the system. Our daily average flow being discharged averages 0.130 MG) with low flow equaling about 0.112 MGD, and high flow equaling ;;ibout 0.149 MGD; that falls into the 15% variance definition. We are checking each 0.300 MGD side of the Oxidation Ditch to insure it is, and remains working, and operational for the time that our flow does increase. Also, please note at our current classification, we are required to conduct 3/week rr n Loring for BOD, TSS, Ammonia, Fecal Coliform, Temp., Dissolved Oxygen, pH, and Total Residual Ch!or,ne. The Town of Newland does not have an on -site laboratory and currently uses contract lab to conduct these analysis, some required of both the influent and effluent. Due to this cost arld the current econcmc conditions, the Town request we be allowed to conduct weekly monitoring for BOD, TSS. Ammonia, :zt;d Fecal Coliform. The Town will conduct the other 3/week monitoring of our field pa: -±meters for pH, Terc o., Dissolved Oxygen, and Total Residual Chlorine as required by our NPDES p rmit. The Town fe::a that since our current flow (0.130 MGD) is only 21% of our permitted flow (0.600 :')IGD), weekly mor Loring of BOO, TSS, Fecal Coliform, and Ammonia; and monitoring our field para;,ieters 3/week wou(.- he representative of our discharges impact to the receiving stream, Vye would expect our monitoring to increase once our flow increases. We hope this explanation provides your office with a better understanding of our request. Should you have questions or need additional information, please contact me at (828) 733-2023. Your attention to this matter and willingness to assist the Town of Newland is greatly appreciated. Sincerely, Keith Hoilman Public Utilities Director
