This appendix contains information on the National Pollutant Discharge Elimination System (NPDES) Phase II storm water permit program for small municipal separate storm sewer systems (MS4s). It contains links to the Storm Water Phase II Compliance Assistance Guide and a series of fact sheets developed by US Environmental Protection Agency (EPA) that give an overview of the Storm Water Phase II Final Rule and Small MS4 program and discuss the six required minimum control measures. Additional information from USEPA is available at www.epa.gov/npdes/stormwater. A copy of the Storm Water Phase II Final Rule (64 FR 68722) that appeared in the Federal Register is available at http://cfpub.epa.gov/npdes/stormwater/cgp.cfm#final2008cgp.
This appendix also contains the General NPDES Permit No. ILR40 for Discharges from Small Municipal Separate Storm Sewer Systems and the Notice of Intent (NOI) for General Permit for Discharges from Small Municipal Separate Storm Sewer Systems. The ILR40 Permit and NOI have been provided by the Illinois Environmental Protection Agency (EPA) who is responsible for administering the program in Illinois. The NOI pdf file is in a read-only format, but a word fillable form is available on the IEPA website.
