RE: SEVENTH EDITION OF LEAK DETECTION METHODS /
Dear Interested Party:
The U.S. Environmental Protection Agency (EPA), Region 10,
Underground Storage Tank (UST) program, acting at the request of
EPA Headquarters and the other EPA Regions, has compiled the
following list of leak detection methods that appear to have met
or exceeded the accuracy requirements stated in the federal UST
regulations (40 CFR 280) . Manufacturers listed have provided
this office with certifications that their product (s) meet
performance standards described in the Standard Test Procedures
for Evaluating Leak Detection Methods (EPA/530/UST-90/xxx) .
The list is divided into seven sections based on method:
Volumetric .Tank Tightness Testing, Nonvolumetric Tank Tightness
Testing, Automatic Tank Gauging Systems, Statistical Inventory
Reconciliation Method, Vapor-phase Out-of-tank Product Detectors,
Liquid-phase Out-of-tank Product Detectors, Pipeline Leak
Detection Systems, and Other Methods (Those for which no
established EPA Procedures are available. ) .
Each section includes 1) the manufacturer's name, address
and phone; 2) the product name and model; 3) accuracy and
applicable comments on the product as stated by the evaluating
party, including probability of false alarm (Pfa) , probability of
detection (Pd) , and operational limitations and requirements such
as tank size and product level; and 4) the name of the evaluator
and evaluation date.
The changes from the SIXTH EDITION are highlighted in PP§.
EPA has not evaluated these certifications, and inclusion ontfiis
list in no way states or implies that EPA approves or certifies
any of these products. Users are also advised to contact their
state UST program because several states maintain a more
restrictive list of leak detection methodologies.
Contact Harold Scott at (206) 553-1587 for any additions,
corrections, or comments.
Sincerely,
Joan Cabreza, Chief
Underground Storage Tank Section
