MEMORANDUM
SUBJECT: List of Leak Detection Evaluations for Underground Storage Tank Systems -
Seventh Edition
FROM: Sammy Ng, Acting Directo:
Office of Underground Storage T;
TO: Addressees (see below) and All Interested Parties
This cover memo transmits the attached list and provides additional information about its
appropriate use and about EPA's involvement with it. Previous editions of the List of Leak
. Detection Evaluations have been very helpful tools to the underground storage tank (UST)
community, and we are pleased to make this new edition available.
The List and Its Use
The List of Leak Detection Evaluations is based on reviews by the independent National
Work Group on Leak Detection Evaluations, consisting of state and EPA UST program staff.
Therefore, this List is not an EPA list. Furthermore, neither EPA nor the work group approve or will
approve leak detection systems for compliance in any particular location. Approval or acceptance of
systems is the responsibility of the implementing agency — hi most cases the state environmental
agency. You should contact this agency regarding the approval or acceptance of leak detection
systems hi a particular area.
The List contains information on underground storage tank and-piping leak detection system
evaluations that have met certain criteria. To be included, an evaluation must have been performed
by an independent third party, hi accordance with EPA or equivalent test procedure (protocol), and
with leak rates blind to the evaluator. The List includes evaluations that followed either an EPA
protocol, a national voluntary consensus standard, or other accepted test procedures developed by an
independent third party.
There is an Under Review section that lists evaluations about which Hie work group has
received information, and is either reviewing or has requested additional information needed to
clarify the evaluation. Listing of an evaluation as "under review" in no way implies that the
evaluation does or does not meet the review criteria.
-------
The List also includes a separate listing of protocols under which listed evaluations were
performed. Finally, some optional maintenance checklists are included; these can help users get
the most out of leak detection systems.
We believe that the List will continue to be of great benefit to those throughout the UST
community. However, please remember that it has inherent limitations. It is based on
evaluations, which are one-time events, often conducted in a lab setting according to protocols
that do not test all aspects of a system. Therefore, appearance on the List does not mean that a
particular system will work or comply with regulations at any particular site. For these reasons,
the List cannot be the final word; you should base your decisions on all available sources of
information.
Distribution
The work group updates the List periodically, as new evaluations and information are
reviewed. The most recent version is always available in electronic form for downloading,
viewing, and printing via the Internet at:
http://www.epa.gov/OUST/pubs/index.htm
It is available in Adobe's Portable Document Format (PDF), Microsoft Word (the original
version), and WordPerfect 5.1. For help with access, contact Hal White at white.hal@epa.gov or
at (703)603-7177.
EPA has printed copies of this seventh edition of the List, but anticipates that future
editions of the List will be available only in electronic format.
Related Evaluation Issues
The List of Leak Detection Evaluations addresses important needs, but there are multiple
other concerns regarding leak detection that we believe need to be better addressed. One need is
for better compliance with the federal, state, and local requirements to conduct leak detection.
The best system is of no use if it is not even used.
Another need is for proper operation and maintenance. The federal regulations require
that leak detection systems be "installed, calibrated, operated and maintained in accordance with
the manufacturer's instructions" (40 CFR 280.40(a)(2)), and it makes good business sense to
perform scheduled maintenance. Despite this, operation and maintenance are often not done.
Thus we have an initiative on Improving Operation and Maintenance. To learn more, please
contact Paul Miller at miller.paul@epa.gov or (703)603-7165.
Finally, there are issues related to the evaluation process, the original EPA standard test
procedures (also called the evaluation protocols), and new technologies and protocols. One issue
is whether revisions are needed to one or more of the existing protocols, to reflect advances in
technology, changes in the way UST systems are operated, advances in the collective knowledge
base about leak detection, and recommendations that regulators strengthen leak prevention and
detection. We welcome input from those familiar with the third-party evaluation process and
with the various protocols available for use, both EPA's and those developed by other
organizations. The contact is Tim Smith; contact information follows.
Additional information
If you have an evaluation to submit or if you have comments about a particular listing,
please see the instructions in the attached memorandum from the Work Group's Chair.
Comments are always welcomed.
I hope that our distribution of this package is helpful to you. If you have questions about
our distribution, please contact Tim Smith. He may be reached by e-mail at
smith.timr@epa.gov, by phone at (703)603-7158, by fax at (703)603-9163, or by U.S. Mail at

MEMORANDUM
TO: Vendors of Leak Detection Equipment/Systems and Other Interested Parties
FROM: Curt D. Johnson, NWGLDE Chair
RE: National Work Group on Leak Detection Evaluation's (NWGLDE) List of Leak
Detection Evaluations for underground storage tank systems - Seventh Edition
Following this memo (and the attachments), you will find the latest edition of our list. In this
edition we have continued our efforts to combine data sheets where possible in order to
streamline the list. We hope this will make the list more convenient and easier to use.
If you need to contact other members in the work group, the necessary information is included
for them after this memo. Also, the work group team and team leaders are listed on the page
following the member list to help you determine who you may need to contact.
Please send new evaluations and/or protocols to be evaluated by the work group to the team
leader and all the members of the team. To enable the work group to properly review the
third-party tests, one (1) copy of all applicable information indicated in the enclosed "Leak
Detection Equipment Review - Document List" must be sent to the team leader and each team
member.
In the interest of expediting third party evaluation reviews, maintaining consistency among
evaluations, and adhering to the accepted evaluation protocols, the NWGLDE has adopted
the following policies:
1. In order for an evaluation to be listed, third party evaluation reports must clearly state
which protocol was used to conduct the evaluation. The Work Group will not review
any evaluations that do not follow either:
a. An EPA protocol, or
b. An alternative protocol reviewed and accepted by the Work Group.
Acceptance must be obtained before the Work Group will begin the evaluation review.
Changes to an existing protocol must be discussed with, and accepted by the Work
Group before testing, or before continuing testing if the evaluator identifies concerns
during testing. Regular communication with Work Group members can expedite the
review. For planning purposes, anticipate at least a six-month review process for a
complete evaluation package.
-------
2. A vendor desiring to list their system as a continuous or automated in-tank leak
detection system should submit an evaluation for that system which followed the
Continuous In Tank Leak Detection System (CITLDS) or equivalent protocol. If
modifications to the CITLDS or equivalent protocol are used, Work Group approval of
the protocol must be obtained before the third party testing occurs. Data used within
this type of system must be automatically gathered and transmitted for analysis and
monitoring.
3. If a problem is discovered with a third party test after a system data sheet has been
added to the List, the vendor shall be given a reasonable time period to provide
information clarifying the test. The data sheet listing will be removed! from the List and
instead listed in the "Under Review" section if:
a. The vendor must re-test the system to correct the problem,
b. The vendor fails to meet the time frame set by the Work Group,
c. The vendor fails to respond to this request.
The system data sheet may be reinstated on the List after all third party test concerns
are resolved. If concerns cannot be resolved or if there is no response from the vendor,
the system will no longer appear on the list.
Since the first draft list was sent out back in January of 1995, the list has sometimes been
referred to as the "EPA work group list of approved leak detection equipment". The work group
and EPA are concerned that similar statements may begin to appear in sales literature distributed
by vendors. We request that you do not refer to the list in this way for the following reasons:
1. This is not an EPA or EPA work group list. This list was prepared by an
independent work group consisting of state and EPA members.
2. Neither EPA nor the work group approve leak detection equipment or procedures. The
draft list does not include "approved" leak detection equipment/procedures. It includes leak
detection equipment/procedures that the work group reviewed and confirmed, were third-
party tested in accordance with either an EPA or other acceptable test protocol, and the test
confirmed that the equipment/procedures met EPA performance standards under test
conditions. Approval or acceptance of leak detection equipment and procedures is the
responsibility of the implementing agency, which in most cases is the state environmental
agency.
We would appreciate any comments you have concerning the list. Please provide comment by
using the list of leak detection evaluations user survey and send survey to me at the address,
phone number, fax number or e-mail address listed on the next page.

DISCLAIMER
This list of Leak Detection Evaluations was prepared by a work group
consisting of State and EPA members and is limited to evaluations of leak
detection equipment and procedures, or systems, that the work group has
completed review of, and that were conducted by an independent third-party
evaluator with leak rates blind to the vendor. This list includes evaluations
conducted in accordance with either EPA Standard Test Procedures for
Evaluating Leak Detection Methods (EPA/530/UST-90/004 through 010) or
other acceptable protocols. The list includes an Under Review category, for
evaluations which the work group's review could not be finalized prior to
publication. The listing of system evaluations as "under review" in no way
implies that the evaluations do or do not meet the criteria for which
evaluations are reviewed.

ASTTest Mass Balance Leak Detection System
BULK FIELD-CONSTRUCTED TANK TIGHTNESS TEST LEAK DETECTION METHOD
Certification: Leak rate is proportional to product surface area (PSA).
For tank with PSA of 5,575 ft2, leak rate is 0.88 gph with PD= 95% and PFA= 5%.
For other tank sizes, leak rate equals [(PSA in ft2 •*• 5,575 ft2) x 0.88 gph].
Example: For a tank with PSA = 10,000 ft2; leak rate = [(10,000 ft2 * 5,575 ft2) x 0.88
gph] = 1.578 gph.
Leak rate may not be scaled below 0.2 gph.
Leak Threshold: Leak threshold is proportional to product surface area (PSA).
For tanks with PSA of 5,575 ft2, leak threshold is 0.44 gph.
For other tank sizes, leak threshold equals [(PSA in ft2 •*• 5,575 ft2) x 0.44 gph].
Example: For a tank with PSA = 10,000 ft2; leak threshold = [(10,000 ft2 - 5,575 ft2) x
0.44 gph] = 0.789 gph.
A tank system should not be declared tight if the test result indicates a loss or gain
that equals or exceeds the calculated leak threshold.

There must be no dispensing or delivery during waiting time.
Minimum of 48 hours.
There must be no dispensing or delivery during test.
Average for product is determined by a minimum of 10 thermistors.
None. Water leaks are measured as changes in level inside tank.
Level and temperature sensors must be checked regularly in accordance with
manufacturer's instructions.
Tests only portion of tank containing product.
As product level is lowered, leak rate in a leaking tank decreases (due to lower head
pressure). Consistent testing at low levels could allow a leak to remain undetected.
Evaluated in a nominal 2,000,000 gallon, vertical aboveground tank with product
surface area (PSA) of 5,575 ft2. Tests conducted in a vertical wall underground tank
may achieve better results.

Coggins Systems, Inc.
Leak Manager with Barton Series 3500 ATG (48 hour test) (72 hour test)
BULK FIELD-CONSTRUCTED TANK TIGHTNESS TEST LEAK DETECTION METHOD
Certification: Leak rate is proportional to product surface area (PSA).
For tanks with PSA of 6,082 ft2, leak rate is 2.0 gph with PD = 97.8% and PFA = 2.2% for 48
hour test and PD = 98.5% and PFA = 1.5% for 72 hour test.
For other tank sizes, leak rate equals [(PSA in ft2 •*• 6,082 ft2) x 2.0 gph].
Example: For a tank with PSA = 10,000 ft2; leak rate = [(10,000 ft2 * 6,082 ft2) x 2.0 gph] =
3.29 gph.
Calculated minimum detectable leak rate is 1.59 gph with PD = 95% and PFA = 5% for 48 hour
test and 1.44 gph with PD = 95% and PFA = 5% for 72 hour test.
Leak rate may not be scaled below 0.2 gph.
Leak Threshold: Leak threshold is proportional to product surface area (PSA).
For tanks with PSA of 6,082 ft2, leak threshold is 1.0 gph.
For other tank sizes, leak threshold equals [(PSA in ft2 •*• 6,082 ft2) x 1.0 gph].
Example: For a tank with PSA= 10,000ft2; leak threshold = [(10,000 ft2 * 6,082 ft2) x 1.0 gph]
-1.64 gph.
A tank system should not be declared tight if the test result indicates a loss or gain that
equals or exceeds the calculated leak threshold.
Applicability: Gasoline, diesel, aviation fuel.
Other liquids may be tested after consultation with the manufacturer.
Tank Capacity: Use limited to single field-constructed vertical tanks larger than 50,000 gallons.
Maximum product surface area (PSA) is 15,205 ft2.
Performance not sensitive to product level.
Waiting Time: Minimum of 12 hours, 20 minutes after delivery or dispensing. Valve leaks and pump drain-
back may mask a leak. Allow sufficient waiting time to minimize these effects.
Waiting times during evaluation ranged from 7.3 to 17.2 hours.
Test Period: Minimum of 48 hours (48 hour test).
Minimum of 72 hours (72 hour test).
There must be no dispensing or delivery during test.
Temperature: Measurement not required by this system.
Water Sensor: None. Water leaks are measured as increase in mass inside tank.
Calibration: The differential pressure sensor must be checked regularly in accordance with
manufacturer's instructions.
Comments: Tests only portion of tank containing product.
As product level is lowered, leak rate in a leaking tank decreases (due to lower head pressure).
Consistent testing at low levels could allow a leak to remain undetected.
Evaluated in a nominal 600,000 gallon, vertical underground tank with product surface area
(PSA) of 6,082 ft2.

Leak Threshold: A tank system should not be declared tight when the vacuum decay is more than 1 inch water column
pressure for non-volatile products and 10% of the lower determined vapor pressure for volatile products.
A tank system should not be declared tight if any water ingress is detected.
Applicability: Gasoline, diesel, aviation fuel, fuel oils #4, waste oil.
Other liquids may be tested after consultation with the manufacturer.
Tank Capacity: Maximum of 12,000 gallons if groundwater is not present.
Maximum of 50,000 gallons if groundwater is present and a vacuum of 1.0 to 1.7 psi can be maintained.
For gasoline, ullage volume must be between 800 and 2,500 gallons.
For diesel, ullage volume must be between 500 and 1,500 gallons.
Waiting Time: None between delivery and testing.
Test Period: Minimum of 2 hours, 30 minutes for gasoline {1 hour, 30 minutes vapor equilibrium recirculation time*
plus 1 hour test period) when groundwater is below bottom of tank.
Minimum of 1 hour, 30 minutes for diesel and less volatile products (30 minutes vapor equilibrium
recirculation time* plus 1 hour test period) when groundwater is below bottom of tank.
Minimum of 1 hour when groundwater is above bottom of tank. Test period based on water ingress
depends on tank size and must be calculated in accordance with manufacturer's instructions.
Test data are acquired and recorded manually.
*The vapor equilibrium recirculation time is the time required to apply a vacuum and to saturate
ullage with vapors.
Test Pressure: Vacuum must be maintained between 1.0 to 1.7 psi at bottom of tank.
Vacuum must not be greater than 4.0 psi in ullage.
Temperature: Vacuum decay is independent of product temperature.
Water Sensor: Conductivity water sensor must be used to detect water ingress and must be calibrated for every test.
Minimum detectable water level is 0.014 inch.
Minimum detectable change in water level is 0.0095 inch.
Minimum water level in tank must be adjusted to 0.014 inch before calibrating the sensor.
Groundwater: Depth to groundwater in backfill must be determined. If groundwater is above bottom of tank,
water sensor must be used and test time extended to ensure water ingress detection during test.
Comments: Not evaluated using manifold tank systems.
Evaluated using gasoline and diesel.
Test may not be effective in some backfill (such as clay) because it may plug holes in tank.
If soil is saturated with product, air or water ingress may not be detected by vacuum
test. A well point in backfill may help identify presence of this condition.

pressure). Consistent testing at low levels could allow a leak to remain undetected.
EPA leak detection regulations require testing of the portion of the tank which routinely
contains product.

LEAK DEECTION METHOD
Certification: Leak rate of 0.2 gph with Pp = 1 00% and PFA =0%.
Leak Threshold: 0.16 gph for single tanks at 99% operating mode.
0.15 gph for manifold tank systems at 99% operating mode.
A tank system should not be declared tight, and a message is printed for the operator, if the test results
indicate a loss or gain that exceeds this threshold.
Applicability: Gasoline, diesel, aviation fuel.
Other liquids with known coefficients of expansion and density may be tested after consultation with the
manufacturer.
Tank Capacity: Maximum of 38,170 gallons for single tanks and for all tanks manifolded together.
Contact manufacturer for tank system applications if total tank capacity exceeds 30,000 gallons.
;_;;, ' " , , " " ' i, ' . ' . ' ' " I
Throughput: Monthly maximum of 221 ,890 gallons.

Waiting Time: Minimum of 3 hours stabilization time is allowed between delivery and data collection.
Test Period: Data collection time ranges from 5 to 28 days.
Data sampling frequency is every 1 to 4 seconds.
| System collects data at naturally occurring product levels without interfering with normal tank operation,
and discards data from unstable periods when system performs test.
Temperature: Average for product is determined by a minimum of 5 thermistors.
Water Sensor: Must be used to detect water ingress.
Minimum detectable water level in the tank is 0.54 inch.
Minimum detectable change in water level is 0.027 inch.
•|
Calibration: Thermistors and probe must be checked annually and calibrated if necessary in accordance with
manufacturer's instructions.
System set-up menu must be checked to verify that the 99% operating mode option has been selected.
Comments: During installation, the set-up menu provides a choice between a 99% or a 95% operating mode.
This evaluation covers only the 99% operating mode. At this time, there is no evaluation covering the
95% mode.
System reports a quantitative result of pass or fail.
Evaluated using both single and manifold tank systems.
Leak rates above 1 gph are either reported as "fail" or as "no idle."
For valid monthly testing, a conclusive test report must be produced for each tank every month.
Systems warns the operator if there are no " passing" tests completed during the month. For very
active tanks, a tank shut down may become necessary in order for the system to collect enough quiet-
time data for a test.
Constant and variable leaks were mathematically induced into tight tank test records which were
collected by systems installed at various active tank sites.
The data base for evaluation of the system included sites with vapor recovery and blending dispensers.
Tanks used in this evaluation contained gasoline and diesel.

consultation with the manufacturer.
Maximum of 15,000 gallons.
Tank must be between 50 and 95% full.
Minimum of 3 hours between delivery and testing.
There must be no dispensing or delivery during waiting time.
Minimum of 6 hours.
Test data are acquired and recorded by a computer.
Leak rate is calculated from data determined to be valid by statistical analysis.
There must be no dispensing or delivery during test.
Average for product is obtained by a single temperature sensor that measures
change in ultrasonic wave velocity.
Must be used to detect water ingress.
Minimum detectable water level in the tank is 1.86 inches.
Minimum detectable change in water level is 0.012 inch.
Temperature sensor and probe must be checked and calibrated in accordance with
manufacturer's instructions.
Not evaluated using manifold tank systems.

NON-VOLUMETRIC TANK TIGHTNESS TEST METHOD (VACUUM)
Leak rate of 0.1 gph with PD = 100% and PFA = 0%.
Leak Threshold: A tank system should not be declared tight when:
sonic emission of air ingress is detected in ullage area and/or;
sonic emission of bubbles formed by air ingress is detected in product-filled portion of the tank and/or;
water ingress is detected at the bottom of the tank.
, . i
Applicability: Gasoline, diesel, aviation fuel, fuel oil #4, waste oil.
Water rhiscible products limit the effectiveness of water ingress detection.
Tank Capacity: Maximum of 75,000 gallons.
The test is generally conducted with tank between 60 and 90% full.
The test may be performed at minimum 5% full if the total ullage volume does not exceed 20,000 gallons.
Waiting Time: None between delivery and testing.
Test Period: Minimum of 1 hour to declare a tank tight (after vacuum is reached) if backfill is dry (no water is detected in
backfill prior to or at the conclusion of test).
No specified minimum to declare a tank "non-tight". If water is present in backfill, minimum test period for
declaring a tank tight is calculated based on the tank size, amount of water present in the tank prior to test,
tank tilt, type of the water sensor and its location.
Manufacturer's time charts should be checked for appropriate test periods.
When test relies on detection of water ingress, minimum test period to declare a tank tight (if the
measurements are taken at the low end of the tank) is 4 hours for the printed circuit board water sensor (test
period may be shorter for tanks smaller than 1500 gallons) and 1 hour for the magnetostrictive water sensor.
When water is present in backfill, an inclinometer must be used to determine and record tank tilt. Tank tilt may
also be determined by taking readings at both ends of the tank. Water sensor should always be used at the
; low end of the tank. If water measurements are not taken at the low end of tank, extended test periods may
be required to detect any water ingress.
• ' ;! " • . • . , !" ]• •
Test Pressure: Vacuum must not be greater than 0.5 psi at bottom of tank.
1
Temperature: Sonic emission is independent of product temperature.
Water Sensor: Must be used at the low point of the tank to detect water ingress.
Magnetostrictive sensor minimum detectable water level is 0.017 inch, and minimum detectable water level
change is 0.001 incru
Printed circuit board sensor minimum detectable water level is 0.022 inch, and minimum detectable water level
change is 0.016 inch.
Groundwater: Depth to groundwater in backfill must be determined. If groundwater is above bottom of tank, test time must
be extended to allow sufficient time to detect water ingress of 0.1 gph.
Comments: Evaluated for manifold tank systems using two 20,000 gallon tanks during the 02/20/96 evaluation.
Evaluated using gasoline, diesel, and JP-4.
Microphone should be located within 60 feet from any possible leak source.
Vacuum test method may not be effective in some backfill (such as clay) because it may plug holes in tank.
If soil is saturated with product, air or water ingress may not be detected by vacuum test.
A well point in backfill may help identify presence of this condition.

Gasoline, diesel, aviation fuel, fuel oil #4, waste oil.
Other fluids which are compatible and soluble with an acceptable tracer chemical may be
tested after consultation with the manufacturer.
Not limited by capacity.
Ranges from 1 week to 4 weeks (normally 2 weeks) after tracer is added to tank.
For very large pipeline systems, several days or weeks may be required to circulate tracer-
labeled fuel through all parts of the pipeline.
Waiting time begins after tracer has reached all portions of the pipeline being tested.
Tracer is added to tank manually or automatically using a metered injection pump at tank fill
or tank discharge pipeline.
Tracer-labeled product must be circulated through pipeline before test period begins.
Pressurized pipeline must be brought up to operating pressure or operated on a daily basis.
Manual dosage of tracer is based on tank size, product volume in tank, and frequency and
volume of tank refills according to manufacturer's recommendations.
Automated pipeline injection uses metered injection pumps to automatically inject tracer
every time product flows through pipeline. Dosage is based on pipeline size and flow rate.
Soil permeability must readily allow tracer movement through the backfill
(greater than 1 Darcy).
Radius of influence of each tracer sampling probe is maximum.10 feet.
Pipeline must be accurately located to ensure that all pipeline surfaces are within the zone of
influence of a sampling probe.
Probes must be installed per manufacturer's guidelines.
Frozen or saturated soil surrounding pipeline may limit effectiveness of this test method.
Groundwater surrounding pipeline may limit effectiveness of test method (e.g. when applied

Comments:
Leak rate is proportional to product surface area (PSA).
For tanks with PSA of 14,244 ft2, leak rate is 1.4 gph with PD = 97.2% and PFA = 2.8%.
For other tank sizes, leak rate equals [(PSA in ft2 - 14,244 ft2) x 1.4 gph].
Example: For a tank with PSA = 20,000 ft2; leak rate = [(20,000 ft2 - 14,244 ft2) x 1.4
gph] = 2.0 gph.
Calculated minimum detectable leak rate is 1.18 gph with PD = 95% and PFA = 5%.
Leak rate may not be scaled below 0.2 gph.
Leak threshold is proportional to product surface area (PSA).
For tanks with PSA of 14,244 ft2, leak threshold is 0.7 gph.
For other tank sizes, leak threshold equals [(PSA in ft2 * 14,244 ft2) x 0.7 gph].
. Example: For a tank with PSA = 20,000 ft2; leak threshold = [(20,000 ft2 * 14,244 ft2) x
0.7 gph] = 1.0 gph.
A tank system should not be declared tight if the test result indicates a loss or gain that
equals or exceeds the calculated leak threshold.
Gasoline, diesel, aviation fuel, fuel oil #4.
Other liquids may be tested after consultation with the manufacturer.
Use limited to single field-constructed vertical tanks larger than 50,000 gallons:
Maximum product surface area (PSA) is 35,610 ft2 (approximately 213 ft. diameter).
Performance not sensitive to product level.
Minimum of 3 hours, 42 minutes after delivery. Valve leaks and pump drain-back may
mask a leak. Allow sufficient waiting time to minimize these effects.
None between dispensing and testing.
Minimum of 49 hours.
There must be no dispensing or delivery during test.
Measurement not required by this system.
None. Water leaks are measured as increase in mass inside tank.
Probe must be checked and calibrated in accordance with manufacturer's instructions.

Leak rate of 0.1 gph with Pp = 100% and PFA = 0%.
A tank system should not be declared tight when there is a substantial increase in the
acoustic noise signal (when the tank is under pressure or vacuum) above the
background signal (prior to pressurization or evacuation) in the frequency interval of 10
kHz to 20 kHz. The acoustic signal to noise ratio is preprogrammed into the computer
and is, not revealed, to or adjustable by the operator.
,' ;' , „ !; , I1:1", '", ' ,,,„„, , , , ,|
Gasoline, diesel, aviation fuel, fuel oil #4, waste oil.
Other liquids may be tested after consultation with the manufacturer.
Equipment is not in contact with the product.
Maximum ullage volume is 7,550 gallons for pressure test and 5,250 gallons for vacuum
test.
None if test is conducted after an underfilled tank tightness test.
Minimum of 15 minutes (includes collection of background information).
Net pressure of 2.0 psi or vacuum of 1.0 psi must be maintained in ullage.
Acoustic Signal is independent of product temperature.
Depth to grpundwater in backfill must be determined. If groundwater is above product
level, vacuum test must not be used. Pressure test must be conducted using net
pressure exceeding 2.0 psi in the ullage.
Test equipment must be checked by tester before each test.
Not evaluated using manifold tank systems.
Evaluated using unleaded gasoline as test product.
Tests only ullage portion of tank.
Product-filled portion of the tank must be tested using an underfill test method.
Microphone was less than 8 feet, 6 inches from the leak source during evaluation.
If the background noise is too high, test is inconclusive. Maximum background noise is
preprogrammed into the computer and not revealed to or adjustable by the technician.
Vibration due to nearby equipment or dripping condensation may interfere with test.
Vacuum test method may not be effective in some backfill (such as clay) because it
may plug holes in tank.
If soil is saturated with product, air or water ingress may not be declared by vacuum
test A well point in backfill may help identify presence of this condition.

VOLUMETRIC TANK TIGHTNESS TEST METHOD (UNDERFILL)
Leak rate of 0.1 gph with PD = 98.12% and PFA = -1.88%.
0.05 gph. A tank system should not be declared tight if the test result indicates a loss or
gain that equals or exceeds this threshold.
Gasoline, diesel, aviation fuel, water, kerosene.
Other liquids may be tested after consultation with the manufacturer.
Maximum of 15,000 gallons.
Tank must be minimum 15% full. There must be at least 20 inches and not more than
67 inches of product in the tank.
Ranges from 3 to 12 hours between delivery and testing.
Testing may begin when the rate of product temperature change does not exceed 0.1
degree F per hour.
There must be no dispensing or delivery during waiting time.
Minimum of 2 hours.
Test data are acquired and recorded by a computer, which does a regression analysis
to determine the leak rate.
An ultrasonic device is used to measure changes in product level.
There must be no dispensing or delivery during test.
Average for product is determined from the measurement of the change in the speed of
sound.
Depth to groundwater in backfill must be determined. If groundwater is above bottom of
tank, product level must be adjusted to provide a minimum net pressure of 1 psi at
bottom of tank during test. (There must be a difference of at least 37 inches between
groundwater level and product level to provide a net pressure of 1 psi at bottom of tank
during test.)
Temperature sensors and probes must be checked annually and calibrated if necessary
in accordance with manufacturer's instructions.
Not evaluated using manifold tank systems.
Tests only portion of tank containing product.
As product level is lowered, leak rate in a leaking tank decreases (due to lower head
pressure). Consistent testing at low levels could allow a leak to remain undetected.
EPA leak detection regulations require testing of the portion of the tank system which
routinely contains product.

Minimum detectable change in water level is 0.005 inch.
Thermistors and probe must be checked and calibrated if necessary in accordance
with manufacturer's instructions.
Not evaluated using manifold tank systems.
Tests only portion of tank containing product.
As product level is lowered, leak rate in a leaking tank decreases (due to lower head
pressure). Consistent testing at low levels could allow a leak to remain undetected.
EPA leak detection regulations require testing of the portion of the tank which
routinely contains product.

BULK FIELD-CONSTRUCTED TANK TIGHTNESS TEST LEAK DETECTION METHOD
Certification: Leak rate is proportional to product surface area (PSA).
For tanks with PSA of 6,082 ft2, leak rate is 2.0 or 3.0 gph with PD = 95% and PFA < .001 %. Choose one to
determine the scaled leak rate and scaled leak threshold for the tank being monitored.
For other tank sizes, scaled leak rate equals [(PSA in ft2 * 6,082 ft2) x (leak rate in gph)].
Example: For a tank with PSA = 10,000 ft2, leak rate = 2.0 gph; scaled leak rate = [(10,000 ft2 + 6,082 ft2) x
2.0 gph] = 3.29 gph.
Calculated minimum detectable leak rate is 0.446 gph with PD= 95% and PFA= 5%.
Leak rate may not be scaled below 0.2 gph.
Leak Threshold: Leak threshold is proportional to product surface area (PSA).
For tanks with PSA of 6,082 ft2 and leak rate of 2.0 or 3.0 gph, leak threshold is 1.777 or 2.77gph
respectively.
For other tank sizes, scaled leak threshold equals [(PSA in ft2 * 6,082 ft2) x (leak rate in gph - 0.223 gph)].
Example: For a tank with PSA = 10,000 ft2, leak rate = 2.0 gph; scaled leak threshold = [(10,000 ft2 + 6,082
ft2) x (2.0 gph - 0.223 gph)] = 2.92 gph.
A tank system should not be declared tight if the test result indicates a loss or gain that equals or exceeds
the calculated leak threshold.
Applicability: Gasoline, diesel, aviation fuel.
Other liquids may be tested after consultation with the manufacturer.
Tank Capacity: Use limited to single field-constructed vertical tanks larger than 50,000 gallons.
Maximum product surface area (PSA) is 15,205 ft2 (approximately 139 ft. diameter).
Performance not sensitive to product level.
Waiting Time: Minimum of 24 hours after delivery or dispensing.
Valve leaks and pump drain-back may mask a leak. Allow sufficient waiting time to minimize these effects.
Waiting times during evaluation ranged from 16.08 to 115.8 hours.
Test Period: Minimum of 24 hours.
There must be no dispensing or delivery during test.
Temperature: Measurement not required by this system.
Water Sensor: None. Water leaks are measured as increase in mass inside tank.
Calibration: Differential pressure sensor must be checked regularly in accordance with manufacturer's instructions.
Comments: Tests only portion of tank containing product.
As product level is lowered, leak rate in a leaking tank decreases (due to lower head pressure). Consistent
testing at low levels could allow a leak to remain undetected.
Evaluated in a nominal 600,000 gallon, vertical underground tank with product surface area (PSA) of
6,082 ft2.
Not evaluated as a stand alone system.
Significant bias of 0.103 gph was detected during the evaluation. Evaluator believes this bias was the result
of product inflow into the tank from valve leaks and product drain back from the pump return line and thus
evaluator did not use this bias in calculating above results.
Performance of the system can be improved by combining results of 2 or more tests. If this option is used,
it is important to determine the number of tests, their timing and the number of passing results necessary to
confirm a tank is tight. The LRDP-24-5 (V1.0) combines the results of 5 tests and is one evaluated option to
improve the performance of this system.

Example: For a tank with PSA = 10,000 ft2, leak rate = 2,0 gph; scaled leak rate = [(10,000 ft2 * 6,082 ft2) x
2,0 gph]« 3.29 gph.

Leak threshold is proportional to product surface area (PSA).
For tanks with PSA of 6,082 ft2 arid leak rate of 2.6"or 3.0 gph, leak threshold is 1.812 or 2.812 gph
respectively.
For other tank sizes, scaled leak threshold equals [(PSA in ft2 * 6,082 ft2) x (leak rate in gph - 0.188 gph)].
Example: For a tank with PSA = 10,000 ft2, leak rate = 2.0 gph; scaled leak threshold = [(10,000 ft2 * 6,082
ft2) x (2.0 gph - 0.188 gph)] = 2.98 gph.

LRDP-24(V1.1)
BULK FIELD-CONSTRUCTED TANK TIGHTNESS TEST LEAK DETECTION METHOD
Certification: Leak rate is proportional to product surface area (PSA).
For tanks with PSA of 6,082 ft2, leak rate is 0.856 gph with PD = 95% and PFA =0.017%.
For other tank sizes, leak rate equals [(PSA in ft2 + 6,082 ft2) x 0.856 gph].
Example: For a tank with PSA = 10,000 ft2; leak rate = [(10,000 ft2 + 6,082 ft2) x 0 856 gph] =
1.407 gph.
Calculated minimum detectable leak rate is 0.446 gph with PD= 95% and PFA= 5%.
Leak rate may not be scaled below 0.2 gph.
Leak Threshold: Leak threshold is proportional to product surface area (PSA).
For tanks with PSA of 6,082 ft2, leak threshold is 0.632 gph.
For other tank sizes, leak threshold equals [(PSA in ft2 * 6,082 ft2) x 0.632 gph].
Example: For a tank with PSA = 10,000 ft2; leak threshold = [(10,000 ft2 * 6,082 ft2) x 0.632 gph] =
1.039 gph.
A tank system should not be declared tight if the test result indicates a loss or gain that equals or
exceeds the calculated leak threshold.
Applicability: Gasoline, diesel, aviation fuel.
Other liquids may be tested after consultation with the manufacturer.
Tank Capacity: Use limited to single field-constructed vertical tanks larger than 50,000 gallons.

As product level is lowered, leak rate in a leaking tank decreases (due to lower head pressure). Consistent
testing at low levels could allow a leak to remain undetected.
Evaluated in a nominal 600,000 gallon, vertical underground tank with product surface area (PSA) of
6,082 ft2.
Not evaluated as a stand alone system.
Significant bias of 0.103 gph was detected during the evaluation. Evaluator believes this bias was the
result of product inflow into the tank from valve leaks and product drain back from the pump return line
and thus evaluator did not use this bias in calculating above results.
Performance of the system can be improved by combining results of 2 or more tests. If this option is
used, it is important to determine the number of tests, their timing and the number of passing results
necessary to confirm a tank is tight. The LRDP-24-5 (V1.1) combines the results of 5 tests and is one
evaluated option to improve the performance of this system.

ATG MAINTENANCE CHECKLIST
* jf -*.
Magnetostrictive and Ultrasonic Probes
Minimum procedurestto be conducted by a qualified service technician.
Has all input wiring been inspected for proper entry and
termination, including testing for ground faults?
Have the probe and sensors been checked for visible damage such
as residue buildup, cracks, or breaks? u
Has the accuracy of the level sensor been tested? 3
Has the accuracy of the water sensor been tested? 4
Has the appropriateness of the high water level alarm setting been
verified? 5
Are all alarms activated and functioning properly?
Yes
Yes
Yes

Yes
No
No
No
No
No
No
Comments:
1. Damaged probes must be cleaned or replaced as appropriate. Probes used in heavier products such as
waste oil should be checked more frequently. Heavier products can leave deposits on the probe shaft and
float assemblies that may restrict the measurement capacity of the probe.
2. Because the magnetostrictive probe consists of moving parts, its sensors can be damaged by excessive
frictional wear as well as residue build-up. Residue build-up can affect the weight of the sensor as well as
inhibit its ability to slide freely along the guide tube. Inaccuracies in the product level measurements could
indicate a problem with the probe sensors. For additional testing of the probe sensors, perform the
following test:
a. Remove the probe from the tank and place it carefully on the ground.
b. Place the water sensor flush with the bottom of the probe shaft and place the product float near
the middle of the probe shaft.
c. Check the height reading on the tank gauge monitor (after allowing sufficient time for the
monitor to respond).
d. Measure the distance from the bottom of the probe to the bottom of the product float and
compare it with the reading on the monitor.
3. To test the accuracy of the product sensor:
a. Using the tank console monitor, take an initial fuel level reading.
b. Dispense one gallon of product into a calibrated container.
c. Using the tank console monitor, take a second fuel level reading.
d. Verify that the change in tank volume is one gallon.
4. To test the accuracy of the water sensor:
a. Remove probe from the tank.
b. By hand, move the water float up the probe to a point higher than the high-water alarm set point.
c. The monitor should respond with a high water alarm report. (The water height may also appear
on the tank monitor display console.
d. Check this height against its actual location.
5. The high water level alarm should not be set so high that water ingress into the tank goes undetected for
long periods of time.
Disclaimer: This checklist is not intended to tell the technician how to perform the maintenance and system
check. Technicians should follow manufacturers' detailed instructions while making sure that all of the items on
this checklist have been covered.

Comments:
1. Damaged probes must be cleaned or replaced, as appropriate. The mass displacement probe is very
susceptible to dirt and residue build-up and should be checked semi-annually and cleaned, if necessary.
Mass displacement probes used in viscous products such as waste oil should be checked more frequently.
Products of this type can leave heavy deposits on the probe which may inhibit the accuracy of the probe.
Checking a reconciliation report and/or manual sticking could verify the system's accuracy.
2. To test the accuracy of the product sensor:
a. Using the tank console monitor, take an initial fuel level reading.
b. Dispense one gallon of product into a calibrated container.
c. Using the tank console monitor, take a second fuel level reading.
d. Verify that the change in tank volume is one gallon.
3. To test the accuracy of the water sensor: (Note: water sensor is separator from the mass buoyancy probe.)
a. Remove the probe from the tank.
b. By hand, move the water float up the probe to a point higher than the high water limit.
The monitor should respond with a high water alarm. (The water height may also appear on the
tank monitor display console.)
Check this height against its actual location.
c.
d.
4. The high water level alarm should not be set so high that water ingress into the tank goes undetected for
long periods of tune.

system is accurate, it has a very small or zero bias.
Activated:
Refers to the state of a qualitative detector's response when indicating the presence of product.
Bias:
An indication of whether the device's measured leak rate consistently overestimates (positive bias) or
underestimates (negative bias) the actual induced leak rate.
Bulk Modulus (of Elasticity):
The ratio of hydrostatic pressure to the relative change it produces in volume.
Continuous Automatic Tank Gauging Method (Continuous ATGS):
These systems use an ATG probe to collect data continually and combine this with software to identify
time intervals when there is no activity in the tank and the data are stable enough for analysis. An
algorithm then combines data from a number of such periods until there is enough evidence to make a
determination about the leak status of the tank. This type of system functions like an ATGS except that
it does not require that the tank be taken out of service for a set period of several hours whenever a test
is to be done. Instead, it uses data from shorter stable time periods and combines the results to
estimate a leak rate and perform a test. The system may default to a standard or shut down ATG test
(requiring the tank to be out of service for a few hours) at the end of the month if sufficient good quality
have not been obtained over the month. These systems are designed to meet the monthly monitoring
performance standard of detecting a leak of 0.20 gallon per hour or 150 gallons per month with 95%
probability of detection (PD) and 5% probability of false alarm (PFA). They test the tank vessel itself.
Continuous Detector:
Detectors that operate continuously, are always present and are never turned off.
Continuous In-Tank Leak Detection Method (CITLDS):
These systems are designed to allow the tank to operate continuously or nearly continuously without
interruption for leak detection tests. They typically have some sensors permanently installed in the tank,
combined with a microprocessor in a console. In addition, they may be connected to the dispensing
meters, allowing for automatic recording and use of dispensing data. There may also be a provision for
direct input of data from a keyboard or pad, to allow for entry of delivery receipts.
Currently there are three types of such continuous systems that are reaching the market. These three
types are referred to as "Continuous ATGS," "Continual Reconciliation," and "Automatic Monthly
Inventory Control."
Detection time:
The sum of rise time and lag time.
Fall 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.

Induced Leak Rate:
The actual leak rate, in gallons per hour (gph), used during the evaluation against which the results from
a given test device will be compared.
Intermittent Detector:
IDetectors 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.
Lag Time:
The elapsed time from the detector's first contact with test product to the first detectable signal.

Leak threshold: ....................... .............. , , ......... t ...............
The measured leak rate at which the system detects the tank to be leaking. This leak rate will always be
tess than or equal to the leak rate requirement for the various release detection methods given in 40
CFR § 280 Subpart D-Reiease Detection. (Please note that some states and other regulatory authorities
may have different requirements). The minimum leak threshold for declaring a leak is experimentally
determined from the results of the evaluation of the release detection system.
Lower Detection Limit:
The smallest liquid concentration or level that a detector can reliably detect (PD > 95%, PFA < 5%).

Manifolded tank systems:
Tanks connected by piping that allow the tank system to function as a single tank. A typical manifolded
tank system usually consists of two tanks connected by a siphon tube that permits the product in the
tanks to be at the same level while product is being pumped out of only 1 tank.
Minimum Detectable Leak Rate:
.The leak rafe that can be detected with a Probability of Detection (PD) of 95% and a Probability of False
Alarm (PFA) of 5%. the minimum threshold is calculated setting the PFA at 5%. For a PD of 95%, the leak
rate is then equal to twice the threshold that gives a PFA of 5% assuming the bias is not significant.
Measured Leak Rate: ................. , ............. ..... |
A positive number in gallons per hour (gph), measured by test device that indicates the amount of
product leaking out of the tank system. A negative number would indicate that something was being
added to the tank. The performance of a system is based on how well the measured leak rate compares
to the actual induced leak rate.

Net Pressure:
In this document this term refers to a pressure difference between the pressure in the tank and the
pressure related to the groundwater. If the net pressure is positive, the pressure in the tank is greater
than that due to groundwater. If net pressure is negative, the pressure in the tank is less than that due
to groundwater.
Nominal Leak Rate:
The set or target leak rate to be achieved as closely as possible during the evaluation of a leak detection
system. It is a positive number expressed in gallons per hour (gph).
Precision:
The degree of agreement of repeated measurements of the same parameter. Precision estimates
reflect random error and are not affected by bias.
Pressure:
In this document this term refers to a pressure which is at or above atmospheric. Any pressure reading
at or above atmospheric is listed as positive; any pressure reading less than atmospheric (vacuum) is
listed as negative.
Probability of Detection (PD):
The probability of detecting a leak of a given size, usually expressed as a percentage.
Probability of False Alarm (PFA):
The probability of declaring a tank to be leaking when it is tight, usually expressed as a percentage.
Probe:

declared or measured.
Product Activation Height:
The minimum height of liquid required to cause sensor activation (this value does not have to meet the
PD> 95%, PfA< 5% criteria).
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.
Relative Accuracy:
A function of systematic error, or bias, and random error, or precision. Smaller values indicate better
accuracy. See entry for "Accuracy."
