Proposed Risk and Technology Review Amendments to Air Toxics Standards for Organic Liquids Distribution

EPA evaluated the risks remaining after fully implementing the 2004 National Emission Standards for Hazardous Air Pollutants for Organic Liquids Distribution (Non-Gasoline) facilities and determined that risks from this source category are acceptable and that the standards continue to provide an ample margin of safety to protect public health and the environment. Following a technology review, 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 proposing to amend the requirements for storage tanks and equipment leaks. EPA is also proposing to offer owners and operators the option of implementing a fenceline monitoring program in lieu of these proposed new requirements for storage tanks and equipment leaks.

EPA is proposing other amendments to the existing regulation. These proposed amendments clarify that the standards are applicable during periods of startup, shutdown, and malfunction; require electronic reporting of performance test results; propose new operational requirements for flares used as control devices; the retention of a standard, the removal of an exemption and the solicitation of comment on an issue for pressure relief devices; and minor rule clarifications.
