49-245.01. Storm water general permit
A. A general permit is issued for facilities used solely for the management of storm water and that are regulated by the clean water act or article 3.1 of this chapter, including catchments, impoundments and sumps, provided the following conditions are met:
1. The owner or operator of the facility has obtained a national pollutant discharge elimination system permit issued pursuant to the clean water act or an Arizona pollutant discharge elimination system permit under article 3.1 of this chapter for any storm water discharges at the facility, or that the facility has applied, and not been denied coverage, for these types of permits for any storm water discharges at the facility.
2. The owner or operator notifies the director that the facility has met the requirements of paragraph 1 of this subsection.
3. The owner or operator of the facility has in place any required storm water pollution prevention plan.
B. If the director determines that discharges of storm water from a facility or facilities covered by this general permit are causing a violation of aquifer water quality standards at the applicable point of compliance, the director may revoke the general permit of the facility or facilities or may require that an individual permit be obtained pursuant to section 49-243. If the director determines that discharges of storm water from a facility or facilities covered by this general permit, with reasonable probability, may cause a violation of aquifer water quality standards at the applicable point of compliance, the director may require a facility or facilities covered by the general permit to obtain an individual permit pursuant to section 49-243.
