Gasoline Dispensing Facility Emissions

Adopted rule

Administrative Order No.: DEQ-4-2024
Filed and Effective: March 25, 2024
See Oregon Bulletin, April 2024

Rulemaking contact: Dan DeFehr, 503-875-5520

The Environmental Quality Commission adopted rules related to vapor control requirements for gasoline dispensing facilities. Air pollutant emissions from GDFs include volatile organic compounds, which can contribute to ozone, or smog, formation, and toxic air contaminants such as benzene. Ground level ozone is a respiratory irritant and can exacerbate conditions such as asthma. GDFs use vapor control devices at two stages of the gasoline dispensing process to capture such emissions. Stage I gasoline vapor systems capture vapors expelled from underground storage tanks at gas stations when being refilled by tank trucks. Stage II vapor recovery systems capture gasoline vapors generated during the dispensing of gasoline to individual motor vehicles or other similar tanks. Enhanced Vapor Recovery systems further capture gasoline vapor emissions at GDFs.

The EQC adopted GDF emission control requirements to reduce emissions of hazardous air pollutants and compounds that lead to ground level ozone formation at various facilities around the state based on how much gasoline the facility dispenses. 

DEQ convened an advisory committee to review the technical issues and fiscal impacts related to the proposed rules. In convening this committee, DEQ appointed members that reflect the range of entities that are both directly and indirectly affected by proposed changes to the rules.
