This is a major problem in florida no specific BMPS for anything other than fleet wash. FDEP needs to give specific maintenance cleaning BMPS for commen cleaning of "example" concrete with or without soap with or without hot water with visible hydrcarbon staining, curb & gutters. Compliant florida contractors know, most PM's,RM's & other PTB dont. They need to be educated but as of now we have nothing written. Local MS4 & local DEP do not give the same answer. Regards
