MSWQS = Mississippi Water Quality Standards

1/Proposed permit limits for Oil and Grease and Total Suspended Solids are comparable to limits placed in permits held by existing similar commercial car wash facilities in the State of Mississippi.  

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.
