Adapting to New EPA Vapor Emission Regulations with John Zink’s Expertise

As industries continue to evolve, regulatory landscapes shift to ensure safety and environmental sustainability. The recent updates to the EPA’s NESHAP Subpart R, BBBBBB, and NSPS Subpart XXa represent significant changes for facilities handling bulk gasoline terminals and vapor control equipment. Understanding and navigating these updates can be challenging, but with John Zink’s expertise and innovative solutions, compliance becomes not just achievable but an opportunity for operational improvement.


Understanding the Regulatory Updates

Subpart XXa

The updated Subpart XXa regulations apply to all new facilities and modified or reconstructed bulk gasoline terminals. Key requirements include:


  • Vapor Recovery Units (VRU): New facilities must ensure total organic compound (TOC) (excluding methane) levels in vents are no higher than 550 ppm, while modified or reconstructed facilities have a limit of 5,500 ppm. Continuous Emissions Monitoring Systems (CEMS) will be required to monitor these emissions.
  • Vapor Combustion Units (VCUs) permitted as Thermal Oxidation Systems: New facilities must achieve a TOC (excluding methane) level of 1 mg/L, whereas modified or reconstructed facilities must meet a 10 mg/L standard. Regular source testing and temperature monitoring are crucial for compliance.
  • VCUs permitted as “Flare” Systems: Flare combustion systems (non-source tested) are not included as a technology option for new facilities. For modified or reconstructed facilities, extensive parameter monitoring will be required to prove compliance.


Subpart BBBBBB

Subpart BBBBBB has been updated to tighten emission limits and monitoring requirements:


  • Emission Reductions: All facilities TOC emissions levels will be reduced to 35 mg/L three years of publication.
  • Monitoring Requirements: Flares and other combustion units will need to adhere to the new parameter monitoring specified in Subpart XXa.


Subpart R

Subpart R will consider all facilities modified or reconstructed 3 years after publication, requiring them to comply with Subpart XXa standards within three years.
