Box 207 Shelby, NC 28151 Subject: Compliance Inspection City of Shelby WTP NPDES Permit No. NCO027197 Cleveland County Dear Mr. Hux :Enclosed is an: amended copy of the Compliance Inspection for the inspection conducted:at the subject facility'ori October.20, 2016; by Ori Tuvia, Maria Schutte and Ed Watson. Wendell Leopa'rd's cooperation during.the site visit was.much appreciated. Please advise the staff involved -with this NPDES Permit by forwarding a copy of the enclosed report.. The following areas of concern were -observed during the inspection: 1) Chain of .Custody's (COC) reviewed during the inspection were incomplete, showing only the. pickup time of the samples, and not showing the arrival time to the lab. = 2) COCs must indicatesamples were shipped on"ice. 3) The utility poles located at well MW -7 appear to be leaching treatment from the poles into. the nearby ground surface. The MRO has concerns that the treatment from the poles may eventually come into contact with groundwater. It also appears that, -since the last. inspection, additional utility poles. have been placed in the area of the. MW -7 well. The poles should be re -located to an area that will not -allowed the treatment to be, able to potentially leach into the soils and possibly become in contact with groundwater. - 4) Previous concerns of: transformers being located. near well MW -8. have been relieved as the electrical boxes near -this well are actually.cable junction boxes that would not have contained materials such as PCBs. Mooresville R.eglonel Office - 0 The report should be self-explanatory; however, should you have any questions concerning this report, please do not hesitate to contact Edward Watson at (704) 235-2198, or at edward.watson@ncdenr.gov.

The wells were protected and maintained with locks present•on the outer well casings. MW -8 well has a number of transformer cable junction boxes placed around this well with the closest box situated at approx. 20 ft. from the well. As these are only cable junction boxes,no PCB's were ever in these boxes. The MW -7 has a large number of treated utility poles placed near this well. These utility poles have been posiitoned near the well for over two years and it appears that the treatment for these poles has leached -out over time. These utility poles need to be re -located to prevent leachate from potentially entering into the soils and possibly impacting groundwater. It alsomappears that additional utility poles have been placed at the MW -7 well location since the last compliance inspection visit in 2015.
