Gasoline distributors across the United States are preparing for significant changes under the U.S. Environmental Protection Agency’s Gasoline Distribution Rules (GDR). These updates—including amendments to NESHAP Subpart 6B and the addition of NSPS Subpart XXa—introduce new emission standards, monitoring requirements, and compliance deadlines that affect bulk terminals, bulk plants, and pipeline facilities.
For many operators, the challenge is not just understanding what the rules say, but how they apply to individual sites, equipment, and planned projects. Barr partners with gasoline distribution clients nationwide to help bridge that gap and support practical, defensible compliance strategies.
Our air quality specialists review regulatory text, background materials, and rulemaking documents to provide clear interpretations of the GDR. We develop plain language summaries, applicability tools, and compliance checklists that help clients determine which requirements apply to their facilities and when those requirements would take effect. Our services have included:
Barr works closely with client environmental and engineering teams to identify potential compliance gaps and evaluate practical solutions. When multiple compliance pathways are available, we outline the associated risks, costs, and operational implications of each option, allowing clients to make informed decisions aligned with their business goals.
Through this work, clients are better prepared to meet upcoming compliance deadlines, manage edge cases, and reduce regulatory uncertainty across their asset portfolios. Barr’s collaborative approach—grounded in technical expertise and an understanding of what’s at stake—helps gasoline distributors move from uncertainty to readiness, supporting safe operations and long-term planning.
