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

The proposed amendment provides non-retail facilities that meet certain conditions and have fleets with 100% 

On-board Refueling Vapor Recovery with an alternate way to comply in lieu of installing Phase II Enhanced 

Vapor Recovery systems certified by the CARB, removes temporary exemptions for dispensing of E-85, 

changes the deadline for submitting monthly gasoline throughput records to a specific date, adds specific 

requirements for backfill inspections, requires compliance with applicable CARB requirements or procedures 

and makes other non-substantial changes to provide clarification, improve enforceability and make 

administrative changes.

Pollutant(s) Regulated by the Rule (Check): ROG (NOX) SO2

 (CO) PM TAC (name): benzene, toluene & xylene

II. EFFECT ON EMISSIONS 

Complete this section ONLY for rules that, when implemented, will result in quantifiable changes in emissions. Attach reference(s) for emission 

factor(s) and other information. Attach calculation sheet showing how the emission information provided below was determined. 

Net Effect on Emissions: Increase* Decrease** N/A 

This source category will have an increased net effect on emissions. Staff conducted an analysis on 120 nonretail facilities with 100% ORVR fleets to obtain data to estimate fugitive emissions. Staff analyzed samples 

collected at the dry breaks of the gasoline USTs and at the connectors to the pressure management system 

and, together with the pressure data, estimated that the total emissions due to the absence of any Phase II 

EVR pressure management system was approximately 428 pounds per year of VOCs (or 1.17 = 1.2 pounds 

per day of VOCs), cumulative at the 120 non-retail facilities. 

Inventory Year Used to Calculate Changes in Emissions: 2008 (based on 2012 AQMP) 

Area Affected: South Coast AQMD 

Future Year Control Profile Estimate (Provide information on as many years as possible): 

The future year control profile is discussed above in Section II.

Name(s) and Location(s) (city and county) of Large (> 100 tpy) Sources Controlled by Rule (Attach additional sheets as necessary): 

IV. EMISSION REDUCTION TECHNOLOGY 

Does the Rule Include Emission Limits that are Continuous? Yes No 

If Yes, Those Limits are in Section(s) (c)(1)(A), (c)(1)(B), (c)(1)(C)& (c)(2)(A) of the Rule. 

Other Methods in the Rule for Achieving Emission Reductions are: N/A

VI. IMPACT ON AIR QUALITY PLAN 

 No Impact Impacts RFP Impacts attainment – emissions forgone 

This source category will have an increased net effect on emissions. Staff conducted an analysis on 120 nonretail facilities with 100% ORVR fleets to obtain data to estimate fugitive emissions. Staff analyzed samples 

collected at the dry breaks of the gasoline USTs and at the connectors to the pressure management system 

and, together with the pressure data, estimated that the total emissions due to the absence of any Phase II 

EVR pressure management system was approximately 428 pounds per year of VOCs (or 1.17 = 1.2 pounds 

per day of VOCs), cumulative at the 120 non-retail facilities. 

VII. SUPPLEMENTAL CALCULATIONS
