REGAN Secretary LINDA CULPEPPER Interim Director Mr. Tommy Spicer Wilkes County Schools 613 Cherry St. North Wilkesboro, NC 28659 NORTH CAROLINA Environmental Quality December 28, 2018 Subject: Compliance Evaluation Inspection Mountain View Elementary WWTP NPDES Permit # NCO046418 Wilkes County Dear Spicer: A Compliance Evaluation Inspection was performed by Division of Water Resources, Winston Salem Regional Office, staff person Justin Henderson, on December 19, 2018. Mr. Tommy Spicer, Operator in Responsible Charge (ORC), was present for -this inspection. This type of inspection consists of two basic parts:' an in -office 'review of the facility files and self -monitoring data and an on -site inspection of the facility. While this inspection mostly 'reflects compliance with Permit No. N00046418, the following concerns requires your attention and action: 1) Proper maintenance of the surface sands filters must be performed at a frequency that will prevent ponding of effluent and/or vegetative growth. Weekly raking is highly recommended to comply with Permit Condition Part II Section C. (2.) which requires the Permittee to properly operate and maintain all facilities and systems of treatment and control at all times. 2) There were no de -chlorination tablets present in the de -chlorination equipment at the time of this inspection. Failure to properly maintain the dechlorination equipment and to adequately replace tablets may result in effluent parameter violations. It is recommended that weekly monitoring of de -chlorination equipment be included in routine maintenance procedures with monitoring frequencies increasing before and after high rainfall events or high-water usage events. 3) Post -calibration records for portable meters were unavailable for review at time to this inspection. Post -calibration of portable meters, utilized for effluent parameter analyses, must be performed and documented and records made available upon request. All calibration records must be maintained for a period of at least 3 years per Permit Condition Part IL Section D. (6.).
