Background

  • AST systems have been a source of emissions in the field due to:

    • component failures

    • exposure to harsh environment

    • maintenance and reliability problems


Slide4 l.jpg

Overview

  • The basic EVR proposal includes several key components

    • Improved components through extended testing

    • Pressure management system to control fugitive emission

    • More stringent pressure decay requirement (TP-206.3)


Slide5 l.jpg

Improving Component Reliability

New requirement includes a 180-day testing period.

Underground storage tank EVR product improvements expected to be applied to ASTs


Slide6 l.jpg

Pressure Management Information

Proposed rulemaking includes a -0.5 pressure requirement

Phase II Hirt System currently being monitored for processor run information


Slide7 l.jpg

Pressure Decay Procedure TP-206.3

Tightens up the allowable leakage for systems

Enables testing of tanks with a 100-gallon ullage

Updates instruments, calibration and gauges for testing


Slide8 l.jpg

Phase I Only

  • District rules exempt tanks from Phase II based on:

    • size of tank (250 to 550 gallons is common)

    • installation date of tank

    • throughput of system

  • Phase I Certification provides

    • improved EVR components for smaller tanks

    • reduced costs to some smaller tanks

AST Tank Inventory

Inventory of 7633 represents approximately one-sixth of fuel carriers reporting information

Better tank size distribution desired - input from stakeholders welcomed

Rulemaking Schedule

Staff report is scheduled to be released on March 5, 2004

Board Hearing Date: April 25, 2004
