Hawaii can now enforce its own underground fuel tank rules, without federal oversight

The US environmental regulators have given Hawaii final approval to run its own program for regulating underground fuel storage tanks. This means Hawaii's state laws and regulations for these tanks are now officially recognized as meeting federal standards.

States often manage their own environmental programs, but they need federal approval to do so. This approval means Hawaii can now enforce its own rules for underground fuel tanks, which are often a source of soil and water contamination. It streamlines the process for businesses in Hawaii, as they only need to comply with one set of rules, not two.
