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”.  

As is found in the existing permit, one special condition of the permit shall be as follows:

The discharge from this facility shall cease and connection made to a regional sewer system when the sewer system is available in the area.  At that time, discharge from the system shall be terminated.
