Source Is Reviewing UST Regulations Across the United States. Here’s What We Know.

The U.S. Environmental Protection Agency introduced new federal underground storage tank regulations in 2015, with a round of compliance deadlines set to hit on Oct. 13, 2018. To help operators understand what is expected of them, Source has compiled a comprehensive state-by-state guide to UST regulations. Click on a state in the map to review your state’s regulations.

Many states operate under a “State Program Approval” (SPA) designation that enables them to act as the regulatory authority in lieu of the federal program, as long as the state regulations meet or exceed the federal regulations. UST operators in states without approved programs must meet federal AND state requirements.

Further, under the 2015 federal regulations, states that currently have approved programs must reapply for SPA by Oct. 13, 2018, to continue operating in lieu of the federal program. According to the EPA, UST operators in SPA states “must continue to follow their state requirements until the state changes its requirements or until the state’s SPA status changes.” (See our article, “UST Regulations in My State: Frequently Asked Questions,” to learn more about this.)

With all of these variables, there is more responsibility on UST operators than ever before to familiarize themselves with their state’s “program approval” status and to understand the state and federal requirements.
