Maryland USTs: New safety rules in 60 days
If you own or operate an underground storage tank in Maryland, you must follow Maryland's updated safety and inspection standards starting 60 days after the rule's publication in the Federal Register. The EPA approved these revisions and the rule says the changes help protect the environment and keep tanks safer without adding extra costs right now.
EPA inspection and enforcement now applies
Maryland's approved underground storage tank provisions will be subject to EPA inspection and enforcement authorities under sections 9005 and 9006 of the Resource Conservation and Recovery Act (RCRA) Subtitle I. That means EPA can inspect and enforce those Maryland UST rules once the approval is final and effective.
