Final Amendments: Air Toxics Standards for Organic Liquids Distribution - Risk and Technology Review

On March 12, 2020, EPA finalized amendments to the 2004 Organic Liquids Distribution (Non-Gasoline) National Emission Standards for Hazardous Air Pollutants (NESHAP). EPA evaluated the risks remaining after fully implementing the NESHAP and determined that risks from the Organic Liquids Distribution (Non-Gasoline) source category are acceptable. In addition, the agency has identified new, cost-effective developments in practices, processes or control technologies that would further reduce emissions of hazardous air pollutants and is finalizing amendments to the requirements for storage tanks.

EPA also finalized minor amendments to the existing regulation. These amendments clarify that the standards are applicable during periods of startup, shutdown, and malfunction; require electronic reporting of performance test results; finalize new operational requirements for flares used as control devices; the retention of a standard, the removal of an exemption for pressure relief devices; the adoption of a work practice standard for tank degassing; and minor rule clarifications.
