TO: All Interested Parties
FROM: Lisf'c. Lund, Acting
Office of Underground Storage' Tanks
RE: Leak Detection Equipment/Procedures Evaluations:
Draft List
Please find attached a draft list of underground storage tank
(UST) system leak detection third-party evaluations. The
attached draft list is being provided for your reiview prior to
publication of the first edition. In general, the draft includes
leak detection system evaluations performed by an independent
third party in accordance with EPA standard test procedures (or
equivalent procedures), with leak rates blind to the tester.
This list was compiled based on reviews by a work group
consisting of state and EPA regulators. This document is
provided for review for accuracy and completeness and is not
intended to be used for any other purpose. This draft list in no
way implies that listed or unlisted leak detection equipment or
procedures do or do not meet the criteria for which evaluations
are reviewed.
The list is divided into three parts, a Summary section, a
Specification section, and an Under Review section. The Summary
section categorizes leak detection systems by the. standard test
procedures, or "protocol," used in the evaluations. The
Specification section lists each system evaluation in
alphabetical order by the name of the system vendor, and contains
the system name, model number, and specifications, and also
contains the name of the evaluator and date of the evaluation.
The Under Review section lists systems about which the work group
has received some information, and is either in the process of
reviewing the third-party evaluation, or has requested additional
information which is needed to clarify the evaluation. Listing
of systems as "under review" in no way implies that the systems
do or do not meet the criteria by which the evaluations are
reviewed. The "under review" category will help vendors
reviewing this draft list determine if the work group has
received a copy of their third-party evaluation.
Please note that multiple evaluations may exist for one system,
and therefore there may be multiple listings for that system.

MEMORANDUM
TO: Vendors of Leak Detection Equipment/Procedures
for Underground Storage Tanks
FROM: Curt D. Johnson
Chairperson
RE: Notice of Formation of Work Group for Review of
Underground Storage Tank Leak Detection Equipment/Procedures
Evaluations
By now, most of you have heard of our work group, which was put
together for the purpose of reviewing leak detection
equipment/procedures evaluations. However, we have come to realize
that you need to know more about the work group so you can better
understand why we are requesting information concerning the
evaluations you have performed on your leak detection
equipment/procedures and what we intend to do with the information you
send us.
Let me begin by providing some history behind the formation of the
work group. Soon after leak detection equipment/procedures were
required to be evaluated to prove its capability to meet EPA leak
detection performance requirements, some states began to take a hard
look at how the evaluations were performed instead of accepting the
results at face value. The states reviewing these evaluations found
most to be well done, but a few that were not properly tested in
accordance with EPA Standard Test Procedures. Many other states
expressed interest in these findings, but did not have the resources
and/or expertise to review the evaluations themselves. At this point
an effort was made to consolidate state and EPA expertise and
resources in a work group for the purpose of reviewing leak detection
equipment/procedures evaluations.
The resulting work group consists of 7 states, 2 EPA regions, and
EPA's Office of Underground Storage Tanks (see attached member list).
It is divided up into teams (see attached team list) which perform a
detailed review of leak detection evaluation results, test data,
calculations, test protocols, operating procedures, etc. in order to
accomplish the following mission as established by the members of the
work group.
The mission of the work group is to review release detection
equipment/procedures evaluations to determine if each evaluation
was performed in accordance with an acceptable protocol, to ensure
that the equipment/procedures meet EPA performance standards.
EPA and member states will share the results of such reviews with
interested parties.
Printed on Recycled Paper
-------
-2-
As discussed In the "Forward" to all EPA Standard Test Procedures,
both state agencies and tank owners prefer that evaluations be carried
out by an Independent third-party. In response to this, work group
members agreed that it was appropriate to review only Independent
third-party evaluations performed in accordance with an acceptable
protocol where leak rates are blind to the vendor.
If an EPA standard test procedure is not available for use to evaluate
a certain type of equipment/procedure, the work group has agreed to
review the test protocol. To avoid problems with evaluations
performed using new protocols, the work group 1s offering to review
them prior to the vendor proceeding with the third-party evaluation.
Prior to member states and EPA preparing a list or incorporating work
group Information into their existing equipment/procedures lists, a
draft of the work group information pertaining to your leak detection
equipment/procedures will be distributed by work group team leaders to
allow for any necessary revisions to be made. In some cases, the
Information will Include an "under review" category for
equipment/procedures where the review could not be completed prior to
the deadline.
It 1s expected that information gathered by the work group will be
available for member states and EPA to establish or revise
equipment/procedures lists prior to the end of FY 1994. Member states
and EPA lists are expected to be finalized and made available to other
states and any other interested parties shortly thereafter. It is
anticipated that member states and EPA equipment/procedures lists may
be used by others as follows:
1. by owners and operators in the selection of appropriate
release detection equipment/procedures for their specific
underground storage tank needs,
2. by vendors of release detection equipment/procedures for
comparison with other vendor equipment/procedures as well as
documents to be presented to other state, county and local
regulatory agencies to gain acceptance in the respective
jurisdiction,
3. by other state and local governments to the desired extent as
a basis for determining whether or not the equipment meets
their requirements, as a reference for comparison (for states
who have their own review process or have more stringent
requirements), or as a reference during field inspections to
ensure that the leak detection equipment/procedures are being
used properly 1n the field.
THE WORK GROUP DOES NOT HAVE THE AUTHORITY TO DETERMINE IF THE
EQUIPMENT/PROCEDURES MEET STATE, OR LOCAL LEAK DETECTION
REQUIREMENTS. Please contact the appropriate local authority to
determine 1f your leak detection equipment/procedures meets their
requirements.
-------
-3-
Work group teams are currently being forwarded third-party evaluations
and protocols through Region 10 EPA. If you have any existing or new
evaluations that you want to send in to be reviewed,, please send three
copies of them to Harold Scott, USEPA Region 10. Mr. Scott's address
1s on the attached 11st of work group members. The information that
is necessary to allow the work group to review an evaluation is
included in the attached document list. The work group intends to
meet approximately every 6 months to finalize the review of any new or
existing evaluations and protocols received by Mr. Scott.
We believe the member states and EPA equipment/procedures lists will
be beneficial to vendors as well as states, local government, and
underground storage tanks owners and operators. However, we need your
help and cooperation to make our effort a success. We strongly
encourage you to work with us 1n this effort by contacting any of the
work group members to discuss any questions or problems that may
arise. A list of member phone numbers and addresses is attached.

VOLUMETRIC TANK TIGHTNESS TEST METHOD
Certification: Leak rate of 0.1 gallon per hour with P0-98.2% & P,A-1.8% for 2 hr test
and P0-99.8% & P,A-0.2% for 4 hr test.
L«ak Threshold: 0.05 gallon per hour (a leak is declared if the output of the measurement
system exceeds this threshold).
Appllcabiity: Gasoline, diesel, aviation fuel, fuel oil *4, fuel oil #6, solvent, waste oil and
other compatible products.
Capacity: The maximum tank capacity is 30,000 gallons.
This equipment is capable of testing a tank at product levels from 20 to
95% full.
Waiting time: Minimum waiting time between delivery and the beginning of the test data
collection must be at least 1 hour.
There must be no product delivery during the test waiting time.
Test Period: The minimum data collection time must be 4 hours to achieve PD of 99.8%
and P,A of 0.2% and 2 hours to achieve PD of 98.2% and PFA of 1.8%.
The test data must be acquired and recorded by a computer.
Leak rate is calculated from the data determined to be valid by statistical
analysis.
There must be no dispensing or product delivery during the test.
Ground Water: Depth to the water table present in the backfill must be determined, and if
it is above the bottom of the tank, product level must be adjusted to
provide minimum of 2 psi net pressure on the bottom of the tank.
Calibration: The load cell must be calibrated before each test.
Comments: This system was not evaluated using manifolded tanks.
This system tests only the portion of the tank containing product.
As the product level is lowered the leak rate in a leaking tank decreases
(due to lower head pressure).

NON-VOLUMETRIC ULLAGE TANK TIGHTNESS TEST METHOD
Certification: Leak raw of 0.1 gallon per hour with P0 -100% & P,A- 0%.
Usk Threshold: Ultrasonic signal when the tank it under pressure or vacuum is compared to
background signal (prior to pressurization). A leak is declared if the ratio
exceeds 1.5 for either 12 kHz or 25 kHz frequency band.
Applicability: Gasoline, diesel, aviation fuel, heavy fuel oils (#2 through #6), solvents, and
waste oil.
Capacity: The maximum ullage volume is 6,000 gallons.
Waiting time: There is no waiting time after product delivery if the test is conducted after an
underfilled tank tightness test.
Test Period: The minimum data collection time is 5 minutes.
The test data is be acquired and recorded by a computer.
Test Pressure: A net pressure of 1.5 psi (or -1.0 psi) in the ullage portion of the tank is
maintained. Tank system must be able to maintain pressure or vacuum with a

Waiting Time: There is no waiting time required after product delivery to the tank.
Test Period: The data collection time (determination of background noise and a leak) is a few
minutes. After the desired pressure has been reached, the tank should be
allowed to settle for ten minutes. Test period also depends on background noise
at the site and on the size of the leak.
Test Pressure: A vacuum blower to produce a vacuum of 1 psi in the ullage portion is used. Or,
a nitrogen pressure of 4 psi at the tank bottom is applied.
Temperature: Acoustical signal is independent of product temperature.
Groundwater: Depth to the water table present in the backfill must be determined. If it is
above the product level, a vacuum test should not be used. The pressure test
may only be used if the ullage test pressure is maintained at a minimum of 1.0
psi higher than the pressure exerted by the water table. If this requires more
than 5 psi at tank bottom, then the ullage test should not be used.
Comments: - This test method was third-party certified using #2 diesel fuel as the test
product.
- During the third-party testing, the microphone was 25 feet away from the leak
source.
- Excess background noise can be a factor in the test result. If background
noise is too high, the test is inconclusive.
- Noise signals are tape recorded (not digitally recorded).
- This test method was not third-party certified with manifolded tanks.
- When testing with vacuum, this test method may not be effective in some
backfill, because some particles (such as clay) may plug a hole in the tank.
- If the soil is saturated with product, this test will not detect air or water
Ingress.

GLOSSARY
January 17, 1995

GLOSSARY J
Aoenitacy: The degree to which the measured leak rate agrees with
the induced leak rate on the average. If a method is accurate,
it has a very small or zero bias.
Le»k threshold: This is the measured leak rate at which the test
method declares the tank to be leaking. This leak rate will
always be less than or equal to the leak rate requirement for the
various release detection (RD) methods given in 40 CFR S 280
Subpart D-Release Detection. (Please note that some states and
other regulatory authorities may have different requirements).
The Minimum threshold for declaring a leak is experimentally
determined from the results of the evaluation of the RD method.
Specificity: Specificity applies to vapor and liquid sensors and
lists products or components of products that these sensors can
detect. Specificity for quantitative sensors is the ratio of
sensor output, or measured concentration, to the actual
concentration of hydrocarbon test gas expressed as a percentage.
Specificity for qualitative sensors is reported as activated if
the sensor responds within 24 hours. Otherwise, specificity is
reported as inactivated.
Ullage Teat: An ullage test tests the un-wetted portion of the
tank, or that portion of the tank that is not in contact with
product. These tests can use a variety of physical phenomena'
including acoustical signals and pressure gain or loss in the
ullage space of a sealed system.
Resolution: The resolution of a measurement system is the
smallest change in the quantity being measured which the system
is capable of detecting.
Precision: The degree of agreement of repeated measurements of
the same parameter. Precision estimates reflect random error and
are not affected by bias.
Probe: A component of a detection system that must come into
contact with product before product can be detected or measured.
Qualitative Responses: The type of detector response that
indicates only the presence or absence of product without
determining the specific product concentration or thickness.
Quantitative Response: A type of detector response that
quantifies the concentration or thickness of product present.
False Alarm:
tight.
Declaring a tank to be leaking when in fact it is
Probability of raise Alarm, P(TA): The probability of declaring
a tank to be leaking when it is tight. It is usually expressed
as a percentage.
Probability of Detection, P(D): The probability of detecting a
leak of a given size and is usually expressed as a percentage.
Activated: Refers to the state of a qualitative detector's
response when indicating the presence of product.
Continuous Detector: Detectors that operate continuously and are
always present and are never turned off.
Intermittent Detector: Detectors that monitor on a regular
basis. An intermittent detector may be a hand held device that
is portable or a permanently installed device that is used to
periodically test for the presence of product.
Response Time: A general term that refers to the more specific
terms of lag time, rise time, and fall time.
Rise Time: The elapsed time from a detector's first detectable
signal in response to the presence of product to an output that
is 95% of full scale for a quantitative detector or activated for
a qualitative detector.
Lag Time: The elapsed time from the detector's first contact
with test product to the first detectable signal.
Detection Time: The sum of rise time and lag time.
Vail Time: The elapsed time after a detector has responded to a
test hydrocarbon and is removed and has recovered to 95% of its
original baseline level or there is no detectable signal output.
Manifolded Tanks: Manifolded tanks are those tanks that are
connected by piping that allows the tank system to function as a
single tank. A typical manifolded tank system usually consists
of two tanks connected by a syphon tube that permits the product
in the tanks to be at the same level while product is being
pumped out of only one tank.
Hominal Leak Rate: The set or target leak rate to be achieved as
closely as possible during the evaluation of a leak detection
method. It is a positive number expressed in gallons per hour
(gal/h).
Induced Leak Rate: The actual leak rate, in gal/h, used during
the evaluation against which the results from a given test device
will be compared.
DRAFT
-------
Measured Leak Sat*: A positive number, in gal/h, measured by the
test device that indicates the amount of product leaking out of
the tank. A negative number would indicate that something was
being added to the tank. The performance of a method is based on
how well the measured leak rate compares to the actual induced
leak rate.
