Storm Water FAQs

The federal storm water regulations require a broad range of industrial facilities to be permitted. They include manufacturing facilities, mining operations, disposal sites, recycling yards, transportation facilities, and other. See Attachment A of the Industrial Storm Water General Permit (IGP) for a complete list of required facilities

The facility operator must submit an NOI for each industrial facility that is required by U.S. Environmental Protection Agency (U.S.EPA) regulations to obtain a storm water permit. The required industrial facilities are listed in Attachment 1 of the General Permit and are also listed in 40 Code of Federal Regulations Section 122.26(b)(14). The facility operator is typically the owner of the business or operation where the industrial activities requiring a storm water permit occur. The facility operator is responsible for all permit related activities at the facility. Where operations have discontinued and significant materials remain on site (such as closed landfills), the landowner may be responsible for filing an NOI and complying with this General Permit. Landowners may also file an NOI for a facility if the landowner, rather than the facility operator, is responsible for compliance with this General Permit.
