Klimek, P.E., Director Division of Water Quality September 12, 2005 CERTIFIED MAIL RETURN RECEIPT REQUESTED Robert Ellis, Treatment Plants Director City of Laurinburg PO Box 249 Laurinburg, NC 28353 SUBJECT: NOTICE OF VIOLATION Bypass at Leith Creek WWTP Permit Number NC0020656 Scotland County Dear Mr. Ellis: On August 1, 2005, Mike Lawyer of our office received a call from Ms. Sherri Monroe of your staff reporting that an overflow had occurred that morning from the lift station located at the Leith Creek WWTP (NC0020656). According to Ms. Monroe, a total of 1,500,000 gallons of untreated sewage bypassed the plant's treatment processes with approximately 1,000,000 gallons entering Leith Creek. The cause of the bypass as reported by Ms. Monroe was due to heavy amounts of rain in a short period of time as well as pump station equipment failure. The large volume of sewage that was lost was attributed to the fact that the Leith Creek WWTP is not staffed twenty-four hours a day and that although the overflow probably began sometime during the night before, it was not discovered until the following morning when staff arrived at around 7:00am. It was relayed to Ms. Monroe that a written report would need to be sent to this office within five days pertaining to the exact cause and details of the bypass. Don Register and Mike Lawyer of this office made a visit to the Leith Creek WWTP on the afternoon of August 1, 2005. This visit was conducted to physically assess the situation, speak with staff at the plant regarding the events and document the affected areas with photographs. During this visit it was discussed that the pumps that send excess flow to the equalization basin failed to operate due to starter malfunctions, which in turn caused the overflow. Mr. Register inquired as to why these pumps were not equipped with telemetry in order to alert staff during such situations. Staff responded that this would be considered. A few days after the August 1, 2005 event, you had a conversation with Mr. Register concerning some of the details of the bypass. You expressed that the influent station was indeed equipped with an auto -dialer, which transmits to the water plant first and then to the police depai tiiient and that you were trying to find out who acknowledged the call. Upon further investigation, you discovered that someone on your staff had intentionally deactivated the telemetry system N°o thCarolintr Natural/if North Carolina Division of Water Quality 225 Green Street — Suite 714 Fayetteville, NC 28301-5043 Phone (910) 486-1541 Customer Service Internet: h2o.enr.state.nc.us FAX (910) 486-0707 1-877-623-6748 An Equal Opportunity/Affirmative Action Employer — 50% Recycled/10% Post Consumer Paper Mr. Ellis Page 2 September 12, 2005 preventing it from notifying personnel who could have responded and minimized the extent of the overflow or possibly prevented the bypass altogether.
