ON 29 SEPTEMBER 2008, the US Environmental Protection Agency (EPA) issued a new Multi-Sector General Permit (MSGP 2008) regulating stormwater discharges from industrial sources. In a change from its previous Multi-Sector General Permit issued in 2000 (MSGP 2000), the MSGP 2008 imposes additional requirements for specific industrial activities2, including certain industrial minerals mining operations.
