Craven, Jr., Owner 420 Marion Drive, Unit 31 Wilmington, NC 28412 SUBJECT: Compliance Evaluation Inspection &Notice of Violation RECEIVED/DENR/DWR NOV Tracking#: NOV-2018-PC-0207 Lakeview Mobile Home Park Wastewater Treatment Plant JUL 10 2018 NPDES Permit#: NC0051713 Water Resources Forsyth County Permitting Section Dear Mr. Craven: Ron Boone, of the Winston-Salem Regional Office of the NC Division of Water Resources (DWR or the Division), conducted a compliance evaluation inspection (CEI) of the Lakeview Mobile Home Park Wastewater Treatment Plant(WWTP) on June 5, 2018. The assistance and cooperation of Randy Bell, Operator in Responsible Charge(ORC),was greatly appreciated. An inspection checklist is attached for your records and inspection findings are summarized below. I. Permit The NPDES permit became effective July 1, 2014 and expires April 30, 2019. The permit states that there is a bar screen at the plant, but there isn't one.This must be corrected at the next permit renewal. II. Self-Monitoring Program A review of the monthly discharge monitoring reports (DMR) for the period June 2013 through June 2018 ' showed that the facility experienced 40 violations during that time frame, all of which have already been addressed via separate correspondence.The plant also had one solids violation and two Ammonia violations in May 2018,which haven't been addressed yet. This is a high number of violations. III. Flow Measurement Mr. Bell stated that he uses the effluent weir and a staff gauge to measure instantaneous flow. However, when Mr. Boone asked Mr. Bell what size the weir is, he stated that"he assumed"the weir was 90-degrees and was reading the corresponding rate from the flow chart. Mr. Boone reports that he believes the weir is only 22.5-degrees. This must be corrected as soon as possible. Using flow chart readings for a 90-degree �� tat3�ir�a�Compares✓-. v State of North Carolina I Environmental Quality 450 W.Hanes Mill Road,Suite 300,Winston-Salem,North Carolina 27105 Phone:336-776-98001 FAX.336-776-9797 e ` . Y weir, when the weir is only 22.5-degrees, will result in highly inaccurate flow readings and may result in violation notices for exceeding the flow limit. For your information, prior to Mr. Bell taking over plant operations from R&A Labs in August 2017, the operators used the park's potable water meter reading to estimate the WWTP's daily flow reading. This is still an acceptable method of measuring flow. IV. Operations and Maintenance Mr. Boone reports that the WWTP is in fair condition. There is some corrosion and dilapidation, and some components are constructed rather haphazardly, such as the chlorination and dechlorination. Plant condition is a direct reflection of the operation and maintenance it has received through the years. Additionally, the high number of violations, mentioned in paragraph II above, is indicative of operational difficulties. At this time, the plant appears to be sufficiently operated and maintained to meet permit limits some of the time. V. Facility Site Review All components of this 0.015 million-gallon-per-day (MGD) facility appeared to be functioning properly. The aeration basin had a dark brown color with very little foam.There were no foul odors but the plant also lacked the earthy odor of a healthy extended aeration activated sludge plant and the dissolved oxygen concentration was about 1.1 milligrams per liter. The effluent from the treatment plant was clear with no foam, surface solids, or scum noted. VI. Records/Reports According to existing records, all required effluent monitoring has been performed in accordance with the parameters and frequencies specified in the NPDES permit. Chains of custody, operations and maintenance logs, operator's visitation logs, etc.,were all readily available for inspection. However, Mr. Bell did not know the location of records produced prior to him taking over operation in August 2017. He had no sludge removal records or septic tank pumping records on site during the inspection. Solids management is critical to the successful operation of the plant. These records must be maintained on site at all times to show proper solids management. This is a violation of Part II, Section D, Paragraph 6, of the permit, which covers records retention requirements. Furthermore, Mr. Bell is unsure of how many septic tanks exist in the park.The permit states that every home has a septic tank but due to the lack of tank pumping records and an accurate park map that shows the location of all septic tanks, the homes that are connected to each tank, and the sewer lines that convey tank effluent to the treatment plant, the number of tanks and their current solids levels is unverified. This lack of information must also be clarified as soon as possible.As the septic tanks are part of the overall treatment process, failure to manage them properly is failure to properly operate and maintain the WWTP, which is covered in Part II, Section C, Paragraph 2, of the permit. y • VII. Effluent/Receivinq Waters The effluent from the facility was clear on the day of the inspection but only a slight trickle was present. The plant discharges to an unnamed tributary of Cuddybum Branch, which is currently classified as a class WS- III (water supply) waters, and is located in the Yadkin Pee-Dee river basin. Please note that the permit mistakenly calls it Cuddybum Creek. This should also be corrected at the next permit renewal. Please work with Mr. Bell to correct the deficiencies noted above in paragraphs 1, 3, and 6. Please reply in writing to this letter with 30 business days of receiving it. Your written reply should address each of the deficiencies noted above and propose corrective action plans and time frames by which each deficiency should be corrected. If you have any questions at all regarding these requirements, please do not hesitate to contact us. Due to the plant's current condition and its violation history, it is highly recommended that you begin now to consider future options to repair/replace this system.A catastrophic failure of some kind in imminent in plants where inadequate funding is provided for proper operation and maintenance. Please be aware that violations of your NPDES permit, or the NC statutes and regulations by which it is promulgated, are subject to fines of up to$25,000 per day,per violation, as set forth in NC General Statute (NCGS) 143-215.6A, Enforcement Procedures, Civil Penalties. If you have any questions regarding the inspection or this report, please contact Ron Boone or me at(336) 776-9800. Sincerely, Sherri V. Knight, P.E.
