Stormwater Program for Industrial Activity: Steps to ComplianceStep 1: Identify your facility — do you need a permit?How do I figure out if I need the
Industrial Stormwater permit? Public (municipal) and private operators of facilities with a Narrative Activity or a Primary Standard Industrial Classification (SIC) code listed in the Draft Multi-Sector General Permit for Industrial Activity are required to apply for a permit. See the complete list of SIC codes and Narrative Activities covered under this program on the link below. The federal regulations are available on the Code of Federal Regulations Web site. Stormwater discharges associated with 11 categories of industrial activities are regulated through the use of National Pollutant Discharge Elimination System (NPDES) permits. Construction Stormwater is one of those categories. Within the 10 remaining categories, there are 29 sectors.
SIC CodesHow do I know what my SIC code(s) or Narrative Activities are?Businesses are designated by their SIC code(s) or by Narrative Activities, often for Commerce/Revenue purposes. One way to determine what SIC codes and Narrative Activities are applicable to your facility is to refer to your federal tax form-the codes are typically located on the upper left of the Schedule C or C-EZ for Sole Proprietors, Form 1065 for Partners, Form 1120 for C Corporations, or Form 1120-S for S Corporations. If you have an NAICS code (North American Industry Classification System Code), you can convert that code to a corresponding SIC code on the NAICScode Web site. So who needs a permit?Any facility that is engaged in a Narrative Activity or a Primary SIC Code, as listed within Appendix D of the Draft Multi-Sector General Permit, needs permit coverage:
How do I look up my SIC codes?
Industrial Permit HistoryThe MPCA public noticed a draft of the general stormwater permit for industrial activity in the fall of 2002.
During the public notice period, the MPCA received written comments on several issues including requirements for outstanding resource value waters and nondegradation analysis, requirements for completed total maximum daily loads, monitoring, and SWPPP’s. In the interim, to address the time between the expired permit and reissuance of the new General Stormwater Permit for Industrial Activity, if you are a previous permit holder, Minn. R. 7001.0160 provides that “any person who holds an expired permit…and who has submitted a timely application for reissuance of the permit may continue to conduct the permitted activity in accordance with the terms and conditions of the expired permit until the agency takes final action on the application…” This rule is available on the Minnesota Water Rules page on this Web site. *** Placeholder for 2009 Draft Permit *** ResourcesCurrent Fact Sheets
