Permit requirements and conditions are representative of those contained in similar permits in the state for car washes.  Effluent Limits have been developed such that the waste treatment system should protect water quality.   However, this permit is subject to modification if future evidence, monitoring results, or nuisance conditions indicate a higher degree of treatment is required to maintain water quality in the receiving stream. There is no monitoring proposed for this permitted discharge. The permit conditions and requirements are based on the “State of Mississippi Water Quality Criteria” and the “State of Mississippi Wastewater Regulations”.   

The facility has access to the City of Flowood sanitary sewer system.  A phone conversation was held with the City of Flowood Public Works Director, Mr. Paul Forster, on August 14, 2023 to inquire whether the City of Flowood wanted the car wash to connect to the sanitary sewer system.  He indicated that since the discharge could possibly contain a significant amount of stormwater he was acceptable to allowing them to continue having their NPDES Permit.
