The purpose of the evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES Permit NC0083551. The ORC, Jim McDonnel,was present during the inspection. This water treatment plant has a discharge of greensand filter, ion exchange backwash and reverse osmosis reject wastewater. An average of 0.347 MGD is discharged into an unnamed tributary to Stones Creek. Required documentation is well organized and complete. The three sedimentation lagoons are operated in series and are well maintained. The flowmeter was calibrated in October, 2018 by Carolina Water Services. Three monitoring wells are sampled and tested for a variety of parameters annually, but this is not a requirement stated in the current permit. Effluent toxicity test results submitted during the last permit cycle showed the potential for aquatic toxcity in the receiving stream. As a result, a Discharge Alternatives Evaluation is required, as part of the current permit, to be submitted with the next permit renewal application. Since the installation of the reverse osmosis system in 2017, the facility has not failed toxcity. The Dixon WTP is in compliance with the NPDES permit NC0083551. Please review the comment section of the inspection report for more details.
