Facility Registration, Storage, & Planning

To protect and prevent the pollution of the Edwards Aquifer and to preserve existing and potential groundwater use, the EAA monitors the storage of regulated substances on the recharge zone and specific portions of the contributing zone. Facilities in these environmentally sensitive areas are required to register with the EAA if they store an aggregate quantity exceeding 1,000 gallons of regulated substances in containers that are less than 500 gallons in size.

Click on the map link below to determine if your facility is located on the recharge zone or on the regulated portion of the contributing zone.
