Alternative Analysis Evaluation: Has the facility evaluated all of the non -discharge options available? Please provide regional perspective for each option evaluated. Spray Irrigation: Considerable amount of farm land directly adjacent to facility. Spray irrigation could possibly be a viable alternative. The operator indicated that the Town has been considering supplementing their NPDES permit with a Non -Discharge permit. Connection to Regional Sewer System: The Town of Pinetops is approximately 3.5 miles away. These two communities should be looked at for possible regionalization. Subsur ace: Not a viable option. Other disposal options: None 5. Other Special Items: PART IV - EVALUATION AND RECOMMENDATIONS The Raleighegional Office has reviewed the current submittal package requesting renewal of the NPDES,permit for the Town of Macclesfield WWTP. Ourstaff has reviewed our files of the above referenced site, performed a site visit and Compliance Evaluation Inspection, in order to make the following comments and recommendations for the request. 1) Please see the attached CEI letter. 2) As mentioned in the section pertaining to Alternatives Analysis Evaluation above, there are other options available to the Town of Macclesfield. Spray irrigation would be another option available to the Town of Macclesfield. This option is supposedly being investigated by the Town and their engineer to use in coordination with their existing NPDES permit. The other option is regionalization with Pinetops. These two towns are approximately 3.5 miles apart. It may be economically feasible, now or in the future, to combine these two wastewater treatment systems into one larger, joint sewer authority, with one discharge. NPDES Staff Report Page 4 Based on the above, the RRO recommends that the subject project be awarded a renewal for their NPDES permit as requested, pending NPDES Unit satisfaction of all requirements.

GOVERNOR Mike Keel, Mayor Town of Macclesfield P.O. Box 185 Macclesfield, NC 27852 Subject: Dear Mr. Keel: NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES RALEIGH REGIONAL OFFICE DIVISION OF WATER QUALITY February 14, 2000 Compliance Evaluation Inspection Town of Macclesfield WWTP NPDES Permit No. NC0050661 Edgecombe County The subject inspection was performed on August 27, 1999, by Tim Baldwin of this office. The cooperation of Phillip Wainwright was appreciated. Below is a numerical listing of the findings during our inspection. 1) The current permit for the above mentioned facility became effective on March 1, 1995, and expires February 28, 2000. The facility has a permitted flow of 0.175 MGD. The facility is a Class II facility. The ORC on record is Phillip Wainwright. 2) The wastewater treatment process train consists of a manual barscreen, a grit chamber, 3 influent pumps, an oxidation ditch with 2 aerating brushes, a "grease trap", a perimeter feed clarifier, a splitter box for RAS and WAS, 2 sand filters, chlorine gas disinfection, chlorine contact chamber, reaeration/backwash chamber, and an effluent flowmeter. 3) The sludge handling process train consists of an aerobic digester and sludge drying beds. Land application of solids is contracted out. 4) One years worth of DMRs (December, 1998, to November, 1999) were reviewed for compliance with permit conditions. Violations are noted on the attached list. Note that values reported as "greater than" are not valid results. Please contact your commercial laboratory and explain that they need to modify their dilutions so that these results do not occur. Please verify that the contract laboratory has been contacted. 3800 BARRETT DRIVE, SUITE 101, RALEIGH, NORTH CAROLINA 27609 PHONE 919-571-4700 FAX 919-571-4718 AN EQUAL OPPORTUNITY /AFFIRMATIVE ACTION EMPLOYER - 50% RECYCLED/109'r, POST -CONSUMER PAPER Mr. Keel February 14, 2000 Page2 5) Laboratory results were checked against the DMR for one month. Everything appeared to be correspond. The operator performs DO, temperature, chlorine, and pH on site, the rest is contracted out to a commercial laboratory. To perform DO, temperature, chlorine, and pH on site, your facility must have a certificate of exemption from the Lab Certification Unit. Please verify that you have a certificate of exemption, or contact the Lab Certification Unit to obtain one at (919) 733-3908. 6) The influent and effluent composite samplers were checked for compliance. The influent sampler read 1 degree C, and takes time proportional samples (29 mL every 30 minutes). The effluent sampler read 1.7 degrees C, and takes flow proportional samples. It is acceptable for the influent sampler to take time proportional samples, however, it must take them at time intervals no greater than 20 minutes, and the sample volume must be at least 160 mL. Please verify that the changes have been made. In addition, please describe the flow proportional sampling method (how many mL per how many gallons flow) of the effluent flowmeter. 7) The flowmeter had last been calibrated on March 24, 1999, which is within the one year requirement. 8) We visited Pump Station #1 and Pump Station #2 during the inspection. Both appeared to be operational, with on -site audible and visual alarms. The Town has a rodder truck, and uses fire trucks to flush sewer lines. They occasionally borrow a jet -vac from Wilson, and they have had certain problem lines smoked and televised. The Division recommends that all lift stations have telemetry, please list which lift stations have telemetry, and which do not. 9) During the inspection it was noticed that the digester had a considerable mat of old sludge with vegetation growing on top. The operator also indicated that "Round -up" is occasionally used on the sludge in the digester to reduce the vegetation. Proper operation of all treatment units is a requirement of the permit. This office recommends that additional mixing (capacity be added to the digester if it is unable to keep everything mixed. We also strongly discourage the application of "Round -up" or other herbicides to any of the biological units at the WWTP. This chemical could have detrimental effects on the operation of the digester due to its biological nature, as well as the oxidation ditch, since digester supernatant is pumped back through the plant. Proper mixing should prevent any vegetative growthijfrom forming. Please provide comments on how the Town intends to address this situation. Please be advised that federal law requires that pesticides can be used only as directed on the label. Mr. Keel February 14, 2000 Page 3 10) The operator indicated that he had a sufficient spare parts inventory, however, he did not have a spare pump for the lift stations. In addition, he indicated that the WWTP did not have a;backup generator on site. This office recommends that a spare pump be purchased for the llift stations to expedite correcting any mechanical problems, and we also recommend that apermanent backup generator be purchased which can run all essential WWTP equipment in case of power loss. Please provide comments on this issue. 11) Several influent BOD values were extremely high, since we are not aware of any industries in Macclesfield. Please explain why there are occasional high values. Please respond in writing to items 4, 5, 6, 8, 9, 10, and 11 by March 17, 2000 detailing actions taken by the Town of Macclesfield to address these items. You are reminded that any violation of the NPDES permit is subject to enforcement action by this Division and/or the U.S. Environmental Protection Ag ncy.
