Are all storm water discharges from construction activity associated with oil and gas field operations exempt from storm water permitting requirements?
No. If the construction related activity results in the discharge of a hazardous substance or oil in “reportable” quantities or in situations when the discharge of a pollutant other than sediment contributes to the violation of an applicable water quality standard, the discharges will continue to be subject to National Pollutant Discharge Elimination System (NPDES) permitting requirements.
