of the CWA Section 402(k) and they cannot become authorized by disclosure to EPA and/or a state via this Notice of Intent to be covered by the permit or 

by any other means (e.g., in the Stormwater Pollution Prevention Plan or during an inspection). If any discharges requiring NPDES permit coverage other than 

the allowable stormwater and non-stormwater discharges listed in Parts 1.1.2 and 1.1.3 will be discharged, they must be covered under another NPDES 

permit. YES NO
