Doesn't really enumerate pollutants. The language addresses "oil and hazardous chemicals", which leaves the enforcement branches (EPA/DEP/DOH) defining what is hazardous. For instance, if you release (trying to recall the precise ppb) so much mercury into an environment... you get into deep shit. Hell, if a waste water operator is found to have above the limit of fecal coliforms(sic) in the effluent for over a set period, that operator and any supervisors/ the company responsible for the plant get multiple 1000's in fines per *day*

Wastewater/water is serious business ._.
