A. 219 East Chatham St. Cary, NC 27511 SCOPE: Installation of a UV disinfection system. SUMMARY: Roaring Gap Club wants to change the disinfection system from chlorination to UV in response to the new requirement to measure TRC to a level of 17 Ng/I. They will keep the existing tablet chlorinator, dechlorinator and contact chamber as a backup during power failures. SUBMISSIONS: Engineering drawings PROJECT EQUIPMENT DESCRIPTION: • Two lamp UV unit rated for 40 gpm, 32,000 micro -watt seconds/cm. • Autodialer to be activated in the event of loss of intensity or lamp failure. RECOMMENDATIONS: The proposed system meets the UV guidelines as specified by the Division. Approval of the AtC is recommended. Backup is provided with the existing chlorination-dechlorination system and an autodialer will call the maintenance staff when the lamps loose intensity or fail.

Per 15A NCAC 2H .0124, there must be a continued treatment and disinfection where the interruption of such treatment would render the waters unsafe for their best intended uses. Therefore, this office would suggest an alternative back-up method to meet the minimum reliability conditions. (i.e., back-up power, dual train, etc.) The UV system does not appear to have an automatic cleaning device to insure maximum radiation for proper disinfection. Also, during the time the system is down for cleaning there must not be an interruption in the disinfection process. cc: WSRO DIEHL & PHILLIPS, P.A.

DIEHL, P.E. JOHN F. PHILLIPS, P.E. ALAN R. KEITH, P.E. We offer the following information in response to your review comments on the referenced project. The design has been modified to use the existing tablet chlorinator and dechlorinator as a backup disinfection system in the event of a power outage. The switchover to the backup disinfection system will be automatic during a power outage, due to the recirculation pump station overflowing (no power for the pumps) to the backup system. In the event of a lamp failure or loss of intensity, the specified U.V. intensity monitor will cause the autodialer to call the Club's maintenance staff. The staff will then either clean or replace bulbs, or operate two valves to divert the effluent through the backup chlorination/dechlorination system. Enclosed are two sets of revised plans (specifications are on the plans) for your review. Please call if you have any further questions.

' .i Please find enclosed three sets of plans (with equipment specifications �4nie p addition of a U.V. disinfection unit at the wastewater treatment system for the Roaring Gap Club. The U.V. unit is being installed to replace the existing chlorination/dechlorination system. This change is being made in response to the Division's notification to Permittees that beginning July 1, 2002, Permittees must measure TRC with an instrument capable of analysis in the 10 to 15- microgram per liter range. Rather than purchasing the equipment necessary for the low level TRC measurement, the Club has decided to install ultra -violet disinfection. As an authorized agent for the Club, I hereby request Authorization to Construct the improvements indicated on the plans. Although these improvements will not be operational by July 1, the maintenance staff for the Club should have the system operational within 60 to 90 days of receipt of the ATC. We request you allow the ORC to continue the current field testing procedures until these improvements can be installed. If it is necessary to request an SOC to prevent enforcement actions and penalties, we can make such a request; however, we hope to have the improvements installed in a shorter time period than that usually required to obtain an SOC. Please advise if you require any further information. Cc: Winston-Salem Regional Office, DWQ Mr. Jay Manner Mr. Hal Transou Yours Very Truly, Diehl & Phillips, P.A. k �-&�- John F.

The Division . issued guidelines for Ultraviolet disinfection systems in November of 2001. The following are part of the requirements of the new guidelines and need to be addressed before we proceed with the issuance of the Authorization to Construct: ■ Since the discharge is to a class B stream, standby power or a chlorination/dechlorination back-up system must be in place unless the permittee can demonstrate to the Director's satisfaction that, in the event of a power outage,or lamp/unit failure, no untreated water will reach waters of the state. Please provide information as to how this requirement is being met. ■ The system shall have an autodialer and audible/visual alarms or a way to alert the operator in responsible charge in the event of a system failure or malfunction. For specific information regarding the UV Guidelines go to our website at http://h2o.enr.state.nc.us/NPDES/NPDESweb.html. Please respond to the questions and provide the requested information prior to September 19, 2002. Thank you in advance for your efforts in responding to this information request. This information will greatly aid the Division in its review of the plans and specifications for the proposed project. If you have any questions, please call me at (919) 733-5083, extension 595.
