There are currently 3 greensand filters, the filters are backwashed approximately once every 2 days. The backwash rate is 1,680 gallons. Well #2 is approved for 36 gpm, which is sufficient to serve the subdivision. The subdivision is fully developed and there is no potential for increased flow. Effluent limitations are implemented based on the new Guidance for Greensand Water Treatment Plants. The Division has determined that the existing Water Treatment Plant is necessary to accommodate social and economic growth in the area and that it will not result in contravention of surface water quality standards or loss of designated uses in the receiving stream.

Works for me. No need to bump the flow up. I was just trying to make your draft of Colonial Woods #1 similar to Sergi's draft of Colonial Woods #2 (NC0088552) since the permits would be combined. There is no flow limit in Sergi's draft. Maybe he is going by the old guidance. Another thought. Just noticed that the footnote for total residual chlorine in Sergi's draft allows the facility 18 months to comply. A good idea since Aqua will need to add dechlor for both Well #1 and Well #2 and they are not know for acting fast. Any problem with including that language in the footnote of your draft for Colonial Woods Well #1? On 9/4/2007 11:44 AM, Toya Fields wrote: Hi Mike, Actually that sentence is a typo. We changed the strategy to require flow limits for all WTP dischargers, mainly because we wanted to build in some way that they would have to notify us if there were an iexpansion. If we kept it without a flow limit, and there were ever an increase, there would be no reason for them to notify us. But the flow limit isn't meant to be restrictive. Its meant to be a reflection of their actual ability to, discharge. So we can bump it up if you think they might have trouble meeting that limit. Toya Mike Mickey wrote: Toya - These comments pertain to the draft permits just received for Colonial Woods Well # 1 (NC0088544) and Mitchell Bluff Well # 1 (NC0088498). Each draft has a flow limit. However, table 4.1 in the _NPDES Permitting Strategies for Potable WTP's_ states that "A flow limit will not be required for these discharges". Can the limit be deleted? No real need for it.

Airy in Surry County. Well #1 of the water system uses an assembly of green sand filters in the treatment of groundwater prior to distribution to the Colonial Woods community. These filters are backwashed, using potable water, approximately once every two days. This facility is an existing, unpermitted discharge that falls under the greensand WTP permitting strategy The applicant did not obtain streamflow data from USGS, however they indicate that the receiving stream is intermittent and estimate that both 7Q10 and 30Q2 are zero. Since filter backwash is not considered to be an oxygen consuming wastewater, this discharge is not prohibited by state regulations. II.

The EAA's contain maps which indicate the existing locations. These are existing groundwater wells that filter water through a series of green sand filters before the water is distributed to the Colonial Woods community. The filters are "backwashed" with water approximately once every two (2) days and approximately 2,000 gallons of water is then discharged into the nearby stream from Well No. 1 and approximately 1,680 gallons of water is then discharged into the nearby stream from Well No.2.

Sammons, Jr. County Manager Surry County 118 Hamby Road Dobson, NC 27017 Subject: Request for Local Government Review NPDES Permit Applications Wells No. 1 & 2 Existing Well Backwash Discharges Colonial Woods Subdivision Surly County Dear Mr. Sammons: 2510 Walker Road Mt. Pleasant, N.C. 28124-8567 704-788-4455 Fax: 704-788-4455 March 12, 2007 Hui J U N - 6 2007 C. - I IAi;:� c':.'.1.I1Y Attached are copies of two (2) applications for permits signed by Aqua North Carolina, Inc. These applications are for permits for the continued discharge of backwash from filters installed on two (2) existing potable wells which serve the Colonial Woods Subdivision, located outside Mt. Airy off Siloam Road. I have also attached a map to indicate the existing locations. As part of the application process, the state requires that we notify the local government and ask that they complete the attached forms which indicates whether the local government has a zoning or subdivision ordinance and whether the continued discharges are consistent with that ordinance. These are existing groundwater wells that filter water through a series of filters before the water is distributed to the Colonial Woods community. The filters are "backwashed" with water approximately once every two (2) days and approximately 2,000 gallons of water is then discharged into the nearby stream from Well No. 1 and approximately 1,680 gallons of water is then discharged into the nearby stream from Well No.2. These have been in service for a number of years and we are not aware of any environmental concerns over these discharges, other than that the state has advised that we must apply for permits. As the state has instructed, we are trying to file these applications as soon as possible. If you could complete, sign and return these forms, it will be very helpful. We apologize for the necessity to ask for this assistance but I hope that you can appreciate our dilemma. If you have any questions or if there is anything we need to discuss, please call me (704-788-4455.) C: Gary Mosely NC DENR 3*. Attachment A. Local Government Review For rn Ge zl Statu e • ..
