1. Gasoline Dispenser Hose Permeation Workshop November 13, 2003 Monitoring and Laboratory Division Air Resources Board California Environmental Protection Agency

2. 2 Agenda Introductions Background for Regulating Hose Permeation Baseline Emission Estimate Suggested Standard Testing Considerations Cost-Effective Analysis Schedule

3. 3

4. 4 SIP Vapor Recovery Measures

5. 5 Gasoline Dispenser Hoses

6. 6 UL 330 - Standard for Safety for Hose and Hose Assemblies for Dispensing Flammable Liquids Six day, 3150 cycle/day flex test Refill hose every 24 hours Divide volume of fuel added over the six days by volume of the hose Allows 30% total loss

7. 7 Hose Permeation Emissions Assume 12 hoses/station Assume gasoline permeation at levels allowed by UL 330 Estimate 3 tons/day statewide

8. 8 SAE J1527 Marine Fuel Hoses Applicable to hoses on pleasurecraft 100 g/m2/day permeation limit up to 1.7 tons/day emission reductions statewide

9. 9 Permeation Regulations Portable fuel containers (CA) –0.4 g/gal/day per TM 513 (SHED) Small off-road engine fuel tanks (CA) –2 g/m2/day per TP-901 Nonroad Large SI Engines and Recreational Engines (Marine and Land) fuel hoses (USEPA) –5 g/m2/day @ 23 deg C per SAE J1527

10. 10 Low Permeation Fuel Hose Technology Entire hose made with low permeation material Low permeation barrier layer(s)

11. 11 Permeation Testing Test existing hoses to refine baseline emission estimate Test prototype hoses to set best achievable permeation limit Identify options for certification test

12. 12 Testing Considerations Durability - aging and cycle tests Pre-Conditioning –fill hose with fuel and wait for saturation Type of fuel Hose configuration –single or co-axial Temperature –typical or worst-case? Cost of test

13. 13 Cost for Low Permeation Hoses USEPA estimates incremental cost of $1.00/ft for engine fuel hoses For 12 foot coax hose => $24 Used $50 increase/hose for initial cost estimate Hoses today cost $100 - $200 (?)

14. 14 Cost-Effectiveness Assume hose life of one year Assume cost increase of $50 per hose Total annual cost = $6,780,000 $6,780,000/yr 1 ton 1 yr 1.7 tons/day 2000 lb 365 days = $5.46/lb

15. 15 hose perm Cost-effectiveness for ARB Major Regulations

16. 16 Tentative Rulemaking Schedule Feb 2004 - complete preliminary tests Mar 2004 - post draft standard and TP Apr 2004 - second workshop Jun 2004 - finalize staff proposal Aug 2004 - release staff proposal Sept 2004 - Board hearing* * schedule may slip due to testing and/or other priorities, but expect Board hearing no later than December 2004

17. 17 Proposed Implementation Schedule Dec 2004* - approved by Board Sept 2005 - finalize rulemaking and begin certification Jan 2007* - required for new installations Jan 2011- required for all facilities * commitment dates in revised SIP Settlement Agreement (June 2003)
