Tier II Information
Locate Chemicals in Your Community
Chemicals that are handled properly and responsibly are safe. However, you have a right to know where and what kinds of chemicals are stored in your area in order to make informed decisions about emergency preparedness for your family and/or community.
DEQ collects information on approximately 50,000 chemical storage locations in Oklahoma under the Tier II reporting provision of EPCRA. This information is provided to fire departments and the Local Emergency Planning Committee (LEPC) in each county. First-responders can use this information for emergency planning, management, and response.
