OrderJuly 1, 2010. If an existing discharger’s site acreage subject to theannual fee has changed, it shall mail a revised annual fee no lessthan seven days after receiving the revised annual fee notification,or else lose permit coverage. All existing dischargers shall beexempt from the risk determination requirements in Section VIII ofthis General Permit until two years after permit adoption. Allexisting dischargers are therefore subject to Risk Level 1requirements regardless of their site’s sediment and receiving waterrisks. However, a Regional Board retains the authority to requirean existing discharger to comply with the Section VIII riskdetermination requirements.5. The discharger is only considered covered by this General Permit uponreceipt of a Waste Discharger Identification (WDID) number assignedand sent by the State Water Board Storm water Multi-Application andReport Tracking System (SMARTS).
