EPA issues or assigns many different kinds of identification numbers, such as registration numbers for pesticide products or permit numbers for hazardous waste sites, wastewater discharges, air emissions or other environmentally regulated facilities, businesses, or sites. States or local governments may also assign identification numbers under various environmental regulations.
You may use the following tools to look up EPA identification numbers:
- Facility Registry System: a centrally managed database that identifies facilities, sites or places subject to environmental regulations or of environmental interest.
- NPDES General Permit Inventory - This search tool allows users to search for NPDES general permits by permit number, permit name, state, EPA region, date issued, date expired, or permit category.
- ECHO (Enforcement and Compliance History Online): compliance and enforcement data searchable by facility ID number.
