This permit is used to regulate facilities that store, handle, use, or generate hazardous materials or hazardous waste throughout Miami-Dade County.  The permit provides operating conditions and requirements as well as guidance for the operators.

It is necessary to protect both the public and the environment from the consequences of improper storage, generation, disposal, or handling of hazardous materials and hazardous waste.

This depends on the type of facility, and location, to be permitted.  If located within any city or municipality, a municipal Occupational License or a Certificate of Use from the city is generally required prior to DERM accepting this permit.  In unincorporated areas of the county, a valid Certificate of Use (CU), or approved CU application must be submitted.  It is suggested that other municipal, county, State and Federal Agencies also be consulted to determine which additional permits must be obtained.

A completed application submitted in person is generally reviewed and answer provided in a matter of minutes.  The actual Operating Permit posted at the facility is usually mailed within thirty days of receiving the complete application and obtaining approval.

The permit fees are based on the type of facility and factors such as holding tank capacity, volume of industrial discharges, and whether the facility discharges to the ground or sanitary sewers.  For specifics, please see the Department’s fee schedule. Please see DERM Fee Schedule.

This permit is generally valid for one year. The permit cycle is as follows:
IW2, 3, or 4 (IW-0)   June 1 though May 31.
