Candace Cox (Pretreatment Coordinator) and Christopher Bortnick (WWTP Superintendent) were present during the Audit. Overall, the program appears to be maintained in compliance with the guidelines of the delegated Pretreatment Program. The Valdese Pretreatment Program has seven SIUs, including one CIU. Previously, the Program consisted of 8 SIUs, however the permit for Valdese Water Recyclers was rescinded in June 2022. There are currently no over allocations and all sampling is being carried out as required. There are no plans to change or modify the Pretreatment Program at this time. NC0041696 17 (Cont.)
