Agenda
Agenda

  • Introductions

  • Background for Regulating Hose Permeation

  • Baseline Emission Estimate

  • Suggested Standard

  • Testing Considerations

  • Cost-Effective Analysis

  • Schedule




Ul 330 standard for safety for hose and hose assemblies for dispensing flammable liquids
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


Hose permeation emissions

Assume 12 hoses/station for Dispensing Flammable Liquids

Assume gasoline permeation at levels allowed by UL 330

Estimate 3 tons/day statewide

Hose Permeation Emissions


Sae j1527 marine fuel hoses
SAE J1527 Marine Fuel Hoses for Dispensing Flammable Liquids

  • Applicable to hoses on pleasurecraft

  • 100 g/m2/day permeation limit

up to 1.7 tons/day

emission reductions

statewide

CARB


Permeation regulations
Permeation Regulations for Dispensing Flammable Liquids

  • 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


Low permeation fuel hose technology
Low Permeation Fuel Hose Technology for Dispensing Flammable Liquids

  • Entire hose made with low permeation material

  • Low permeation barrier layer(s)


Permeation testing
Permeation Testing for Dispensing Flammable Liquids

  • Test existing hoses to refine baseline emission estimate

  • Test prototype hoses to set best achievable permeation limit

  • Identify options for certification test


Testing considerations
Testing Considerations for Dispensing Flammable Liquids

  • 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


Cost for low permeation hoses
Cost for Low Permeation Hoses for Dispensing Flammable Liquids

  • 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 (?)


Cost effectiveness
Cost-Effectiveness for Dispensing Flammable Liquids

  • 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
Tentative for Dispensing Flammable Liquids 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


Proposed implementation schedule
Proposed Implementation Schedule for Dispensing Flammable Liquids

  • 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)
