Rule Title(s): Storage And Transfer of Gasoline

Date Submitted to ARB: April 10, 2009

If an Amended Rule, Date Last Amended (or Adopted): November 11, 2003

District Contact: Donald R. Price Phone Number: 805/645-1407 E-mail Address: don@vcapcd.org

Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule 

The revised rule provides an exemption from Phase II vapor recovery for fleets equipped with Onboard Refueling 

Vapor Recovery (ORVR). It also provides an exemption from Phase II vapor recovery for E85 (ethanol) fueling 

facilities.l A restriction is placed on standing gasoline in Phase I spill containment devices. There is a new 

requirement for the daily inspection of hanging hardware and a new requirement for permit holders to submit test 

results within 14 days. The effective date of the revised rule is April 1, 2009.

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: The proposed exemption for ORVR will result in no measurable increase or reduction in ROC emissions in 

Ventura County. As noted in the EPA guidance letter of December, 2006, EPA assumes that, when ORVR penetration is 

above 95 percent, ROC emissions from the two systems (ORVR and Phase II VR) will be comparable and consistent with

the "widespread use metric" in federal law. In addition, the ROC emission reduction expected from other proposed 

revisions to Rule 70 is considered unmeasurable because the length and severity of excess emission episodes cannot be 

measured.
