Effective on January 1, 2020 all business license applications (new or renewal) must demonstrate compliance (or enrollment) with the General Permit for Stormwater Discharges Associated with Industrial Activities. The purpose of SB 205 is to protect water quality including the health and safety of drinking water sources statewide.

Not all businesses are affected by SB 205.  Below are types of businesses with SIC codes that fall under SB 205 (this information is included in Attachment A of the Industrial General Permit):
