Gasoline Dispenser Hoses

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
Hose Permeation Emissions
• Assume 12 hoses/station
• Assume gasoline permeation at levels allowed by UL 330
• Estimate 3 tons/day statewide
8
SAE J1527 Marine Fuel Hoses
• Applicable to hoses on pleasurecraft• 100 g/m2/day permeation limit
up to 1.7 tons/day

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

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
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)
