Home My WebLink AboutNC0025453_Historical information_20151231May 20 2015 Subject: Dear Mr. Warren: Pat McCrory Governor In order to gather the appropriate data, all effluent mercury analysis must be conducted using the low level Method 1631 E. This could be accomplished through the NPDES permit as a monitoring requirement, butthat may require more frequent sampling than what is required by the Pretreatment monitoring plan. Therefore, if you are not already doing so, beginning July 1, 2015 any effluent analysis for mercury must be done using EPA test Method 1631 E. You do not have to update your monitoring plan at this time; a copy of this letter in the file will document this requirement. Thank you for your continued cooperation with the Pretreatment Program. If you have any questions please contact me at (919) 807-6383 or via email [Deborah.Gore@ncdenr.gov]. As you may know, in 2012 North Carolina adopted an EPA approved statewide mercury total maximum daily load (TMDL). To demonstrate compliance with the TMDL Permittees must be able to quantify the amount of mercury being discharged from point sources to the lower reporting level of the procedure. 1601 Mail Service Center, Raleigh, North Carolina 27699-1601 Phone: 919-707-8600 \ Internet: www.ncdenr.gov An Equal Opportunity \ Affirmative Action Employer - Made in part by recycled paper Donald R. van der Vaart Secretary James Warren Town of Clayton P.O.

The 2.5 MOD water reclamation facility consists of the following units: influent head works with a biofilter odor control system that includes a Fiberglass Reinforced Plastic (FRP) cover; mechanical and automatic bar screens; a vortex type grit removal system; influent pump station with three (3) 60 Hp dry pit submersible pumps and one 40 Hp pump; 9 inch Parshall flume with ultrasonic flow meter; a 214,500 gallon anaerobic selector tank in front of the first stage anoxic tank; a 300,000 gallon first stage anoxic tank in front of oxidation basin # 2; 2 - oxidation basins; a 200,000 gallon first stage anoxic tank in front of oxidation basin # 1; three (3) secondary clarifiers; Return Activated Sludge pump station; two shallow bed DAVCO traveling bridge type tertiary filters; UV disinfection, two banks, with back-up chlorination / dechlorination; effluent pump station; one 90,000 gallon aerated digester/sludge stabilization tank; two - 360,000 gallon aerated sludge holding tanks; sludge loading station; a sludge thickening building containing two (2) rotary drum thickeners with polymer flocculation; sludge transfer pump station; sludge drying beds; in- plant non-potable water system using reclaimed treated wastewater; a reclaimed water pump station and transmission force main to the Pine Hollow Golf Course and two on-site generators and one portable generator to provide back-up power. Hayes of the Raleigh Regional Office conducted a compliance evaluation inspection of the subject facility. The assistance of James Warren, grade WW-4 Operator in Responsible Charge (ORC), and William Simpson was appreciated. Please find the attached Basin Wide Information Management System (BIMS) inspection checklist summarizing each inspection. Below is a list of recommendations and findings developed from the inspection: _L North Carolina Department of Environmental Quafity 1_ 3. 4. 5. S^icereiy, cc: Permit files Central files At the time of inspection, the biofilter odor control system appear to be operating normally based on very little odor at the influent head works. The automatic and manual bar screens and vortex grit removal system were functioning normally. The number 1 aerated sludge holding tank was approximately 20% full. The number 2 aerated sludge holding tank was approximately 60% full. Aerators in sludge holding tank number 1 and 2 were operational. Sludge was not being thickened in the rotary drum thickener at the time of inspection. Influent in the two oxidation basins was medium brown in color with very little foam. DO flowing out of oxidation basin number 2 was 1.34 mg/l. Covers have been placed over the anaerobic selector to prevent odor. The #2 secondary clarifier was being taken down for general maintenance. Effluent appeared clear flowing off the weirs in secondary clarifiers 1 and 3. Effluent in the wet well at the tertiary filters appeared clear with no foam. The sludge drying beds had no sludge in them. Biosolids are land applied under the Town of Clayton Land Application Permit WQ0023178. The permit will was reissued May 19, 2015, became effective October 01, 2015 and will expire September 30, 2020. Granville Farms is designated the back-up hauler to land apply biosolids under the GFI Residuals Land Application Program under permit WQ0000838. A Certificate of Approval was issued December 17, 2010 to Johnston County Residuals Dewatering Facility to accept up to 150 dry tons of residuals per year from Little Creek Water Reclamation Facility. The laboratory was checked in a cursory manner. Little Creek Wastewater WRF laboratory analyzes BOD, TSS, fecal coliform, Phosphorus, Nitrate, COD and is field certified for TRC, pH, temperature, DO, specific conductance. Environment One is the contract lab that analyzes all other parameters. All instruments, meters, probes, photometric cells are maintained in good condition. All standards, reagents and consumables used are within expiration dates. Danny Smith, Regional Supervisor Water Quality Regional Operations Section Raleigh Regional Office I would like to thank James Warren and William Simpson for their time and assistance with this inspection.
