(A) Every storm water treatment practice shall have an acceptable form of water quality pretreatment, in accordance with the pretreatment requirements found in the current storm water design manual.
(B) As specified in the storm water design manual, even with pretreatment, certain storm water treatment practices are prohibited in the following circumstances:
(1) Storm water is generated from highly contaminated source areas known as “hotspots.”
(2) Storm water is carried in a conveyance system that also carries contaminated, non-storm water discharges.
(3) Storm water is being managed in a designated groundwater recharge area.
(4) Certain geologic conditions exist (e.g., karst) that prohibit the proper pretreatment of storm water.
