All stormwater runoff from these projects shall be in accordance with the attached schedules as follows. Section A — Final Limitation and Controls for Stormwater Discharges Section B — Schedule of Compliance Section C — General Conditions STANDARD CONDITIONS FOR GENERAL PERMITS Any other discharge to surface waters of the state is prohibited unless covered by another permit, authorization or approval.

GENERAL PERMIT COVERAGE All persons desiring to be covered by this General Permit must register with the DWQ by the filing of a Notice of Intent (NOI) and applicable fees.
