Industries that fall under the above categories may be exempt from having to obtain an industrial storm water permit if they do not have Storm Water associated with industrial activity. A Certification of Non-exposure is available to those who fall under this category. The certificate will take you through a series of questions concerning the facility, finishing with a certification statement.
If your facility qualifies, you don't have to obtain a permit. You are required to send the Certification of Non-exposure to the state with a copy to the city. The certification must be renewed every five years.
