Sullins, Director Division of Water Quality Ronald D Autry City of Dunn PO Box 1065 Dunn NC 28335 November 19, 2008 SUBJECT: November 12, 2008 Compliance Evaluation Inspection City of Dunn Dunn WWTP Permit No: NC0043176 Harnett County Dear Mr. Autry: Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted on November 12, 2008. The Compliance Evaluation Inspection was conducted by Mark Brantley, Environmental Chemist, of the Fayetteville Regional Office. The time and cooperation of Dean Gaster, Public Utilities Director, Donrie Dukes, Facility's Grade IV ORC, and Gary Barefoot, Grade II Operator, was greatly appreciated. The facility was found to be in Compliance with permit NC0043176. As a reminder, preservation of the Waters of the State can only be achieved through consistent NPDES Permit compliance. Comments • Facility was clean and neat in appearance at the time of the inspection. The facility appears to be maintained well and several positive operational changes have been made to make the plant run more efficiently. However, the Division of Water Quality does not, agree with the practice of storing chlorine gas and sulfur dioxide gas in the same area because of a public safety concern and the safety of plant personnel. Currently these gases are stored in one -ton cylinders at the WWTP. If one of these tanks were to rupture a significant area would be impacted such as the area hospital, surrounding medical area, and the possible closure of several main highways. The division has noted this in inspections during the past few years. During the inspection Mr. Dean Gaster stated that the city was in the planning stages for switching to liquid bleach for chlorination and a liquid dechlorination agent for dechlorination. The Fayetteville Regional Office strongly supports this action and encourages the City to • move forward with these plans as quickly as possible. By switching td a liquid chlorination/dechlorination system the City would be taking a proactive step in ensuring the safety of its citizens and plant personnel. Please note that safety precautions must be taken with liquid system but the danger with this system is significantly less than the dangers associated with the current gas system. • It was noted during the inspection that this facility is not covered under a NPDES General Stormwater Permit (NCG110000 series). Since this facility is permitted for more than a million gallons per day flow and it has a point source discharge for stormwater it is necessary to apply for a NPDES General Stonnwater Permit. Enclosed is an application for the permit along with its technical bulletin that contains some useful information. Please submit a completed application no later than December 15, 2008. —North Carolina Division of Water Quality/Aquifer Protection Section 225 Green St./ Suite 714 Fayetteville, NC 28301 Phone (910) 433-3300 FAX (910) 486-0707 Internet: h2o.enr.state.nc.us Customer Service 1-877-623-6748 An Equal Opportunity/Affirmative Action Employer— 50%Recycled/10% Post Consumer Paper One NorthCarolina 7atill"al y Please refer to the enclosed inspection report for additional observations and comments.

Key Permit Requirements • Implement a Stormwater Pollu- tion Prevention Plan (SPPP) (Part II, Section A). • Provide secondary containment for all bulk storage of liquid mate- rials. (Part II, Section A, 2.(b)). • Perform and document semi- annual qualitative monitoring during a representative storm event. (Part II, Section B). Perform semi-annual analytical monitoring for vehicle mainte- nance area, if present, and submit • the results on the monitoring re- ' port forms provided with the per- mit. (Part II, Section C). ' What are BMPs, and why are they important? The SPPP should include the use of Best Management Practices (BMPs) to. control discharge of pollutants from a facility's stormwater out - .falls. BMPs include a variety of things that the industrial facility can do to minimize the potential for pollutants to get into the stormwa- ter draining from a facility. There are different types of BMPs: Non -Structural BMP's Non-structural (practices or activi- ties) BMPs include: * Eliminate exposure of materials and equipment wherever possible by moving materials and equip- ment to indoor locations. * Practice good housekeeping on - site. Keep materials handled and stored atthe facility in an orderly fashion. ' * Exchange hazardous materials for non -hazardous ones wherever possible: '* Establish routine leak and main- tenance checks to minimize the chance of spills before they occur. PAGE 2 TECHNICAL BULLETIN FOR N.C. GENERAL STORMWATER PERMITS NCGOS, 07, I I, & 13 LAST REV. 5/15/08 What does this permit require me to do? (continued) When spills occur, clean them up immediately. * Establish bulk storage tank protocols that minimize the risk of spills during -loading and unload- ing procedures. * Store used pallets and process waste dumpsters inside or under a roof where water cannot flow on or around them. Structural BMPs Structural (equipment or devices) BMPs include: * Build containment dikes around the loading areas of bulk liquid storage containers. * If practical, change painting op- erations from liquid systems to powdered systems that do not Could 1 monitor at fewer outfalls? All outfalls associated with vehi- cle maintenance must be moni- tored. However, the facility may request approval of "Represent- ative Outfall Status." This status allows analytical monitoring at fewer outfalls. To request repre- sentative outfall status, send a letter to the DWQ Regional Office explaining which outfall(s) can be considered representative of other discharges and include all neces- sary supporting documentation. Where can I find more information? Additional information is avail- able at our website (see right). Another valuable source is the Division of Pollution Prevention and Environmental Assistance. The DPPEA has specific informa- tion about how to minimize pol- lutants at various industries. Call (919) 571-4100 or visit generate solvent wastes. * Build roofs and secondary con- tainment around materials stored outside where stormwater cannot contact them. Could I be exempted from an NPDES stormwater permit? Possibly. A facility with any indus- trial activity subject to the NPDES Stormwater regulations that elimi- nates all potential stormwater ex- posure may be eligible for a No Ex- posure Exclusion from a stormwa- ter permit. A facility that meets this condition may submit a No Ex- posure Certification application form (see NC DWQ's Stormwater Do I need a certified lab to analyze stormwater. samples? Monitoring under all NPDES per- mits must be conducted in accor- dance with test procedures ap- proved under federal regulations in 40 CFR §136. All labs certified by North Carolina perform analysis in accordance with those procedures. While N.C. certification require- ments do not apply to stormwater only discharges, any data gathered under an NPDES permit must con- form to federal requirements. Us- ing a certified lab is one way to en - Permitting Unit's website: ) to apply for a No Exposure Exclu- sion. The facility must re- certify No Exposure every five (5) Years. What if I sell my business, or the name of my business changes? This change is a minor modifica- tion and requires the Director's approval. You should complete the Name/Ownership Change Form SWU-239. This form is downloadable from our website, sure compliance with these re- quirements. A list of certified labs is available from: i'ti ,:.'1;_'_, :..; • Note that pH is a field parameter and must be measured within 15 minutes. You must either train on -site staff to measure pH in accordance with approved methods or contract with commer- cial services. All entities with field parameter certification as per 15A NCAC 2H .0800 can ana- lyze pH in accordance with federal procedures (see website for list). Who can help me with questions?
