       List of Leak Detection Evaluations for Underground Storage Tank Systems -
       Fifth Edition
       Anna HopTans Virbick, Director
       Office of Underground Storage Tanks

       Addressees (see below) and All Interested Parties
                 The purpose of this cover memo is to transmit the attached list and to provide 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.

                 As only one hard copy is being sent to each location, if you are not the appropriate
           person in your organization to receive this, please forward it to the correct person and
           provide us with updated address information.

           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 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 --in most cases the state
           environmental agency. You should contact this agency regarding the approval or acceptance of
           leak detection systems in a particular area.

                 The List contains information on underground storage tank and piping leak detection
           system evaluations that have met certain criteria. The evaluations  must have been performed by
           an independent third party, in accordance with EPA or equivalent test procedures, .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 the 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 includes a user survey; the work group asks that, after familiarizing yourself
with the List, you take a moment to provide your feedback. 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 qpntinue to. be of great benefit to those throughput 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
       This edition is being distributed in both hard copy and made available in electronic form.
The previous edition was made available only electronically. 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 Microsoft Word (the original version), WordPerfect 5.1, and Adobe's Portable
Document Format (PDF). For help with access, contact Hal White at white.hal@epa.gov  or at
(703)603-7177.

       To save paper and expense, we limit the distribution of paper copies of this large
document. We send paper copies to vendors, associations, EPA UST offices, state UST offices,
and others who request it -- one copy to each organization at each location.  In addition, a limited
number of printed copies will be made available through EPA's National Center for
Environmental Publications, (800)490-9198; mention the document number at the top right hand
comer of this memorandum.

Additional information
       If you have an evaluation to submit or if you have comments about a particular listing,
please see the list of work group leads for the various types of leak detection systems and  contact
the appropriate lead person.  Vendors are responsible for submitting updated information to the
appropriate work group team; doing so avoids possible work stoppages in the field.  Comments
are always welcomed.

MEMORANDUM

TO:     Vendors of Leak Detection Equipment/Procedures and Other Interested Parties

FROM:  Curt D. Johnson, Chairperson

RE:     National Work Group on Leak Detection Evaluation's List of Leak Detection
        Evaluations for underground storage tank systems - Fifth Edition

If you are reading this memo, you have received our latest edition of the list. 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.

If you need to contact other members in the work group, the same information is included, for them on the next page.
Ateo, 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.

Ptease 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.

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 draft 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 meet EPA performance standards. 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 try to send only 1 copy of the list per company per location. If you received more than  1 copy at your location, or if
the copy needs to be sent to another person, please  notify me and we will make the  necessary corrections.

                   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.

Leak rate of 0.2 gph with PD=95.4% and PFA=4.6% (calculated
based on a 1-hourtest).

0.1  gph. A 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, fuel oil, waste oil, and solvents.

Maximum of 15,000 gallons.
Tank must be between 50 and 95% full.

Minimum of 15 hours between delivery and testing.
There must be no delivery during waiting time.

Minimum of 2 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.

Product measurement not required. System measures product mass (which is not affected
by temperature) instead of product volume.

Must be used to detect water ingress.
Minimum detectable water level in the tank is 0.175 inch (0.27 inch for waste oil).
Minimum detectable change in water level is 0.088 inch (0.031 inch for waste oil).

Mass measurement probe and water sensor must be checked and calibrated if necessary in
accordance with manufacturer's instructions.
System is battery operated and does not automatically generate a hard copy of the leak
test result. However, a hard copy of the results can be obtained by transfer of data to another
unit (see manufacturer'sinstructionsforfurtherdetails).
System is not equipped with any alarms (e.g. high water alarm, or failed leak test alarm).

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). Consistenttesting 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.
2000-X model (which was certified for use on tanks up to 30,000 gal capacity) and 2000-XB
 model (which was certified for use on tanks up 72,948 gallons) are still under review.

 Leak rate of 0.1 gph with PD=99.8% and PFA=0.2% for 4 hr test.

 0.05 gph. A 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, fuel oils #4 and #6, waste oil, and solvents.
 Other liquids may be tested after consultation with the mariufacturer.

 Maximum of 30,000 gallons.
 Tank must be between 20 and 95% full.

 Minimum of 1 hour between delivery and testing.
 Minimum of 1 minute between dispensing and testing.
 There must be no delivery during waiting time.

 Minimum of 2 hours to achieve PD = 98.2% and PFA = 1.8%.
 Minimum of 4 hours to achieve PD = 99.8% and PFA = 0.2%.
 Test data are 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 delivery during test.

 System measures product mass (which is not affected
 by temperature) instead of product volume.

 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 2 psi at bottom of tank during test. There must be a difference of at
 least 73 inches between groundwater level and product level to provide a net
 pressure of 2 psi at bottom of tank during test.

 Load cell must be calibrated before each test,        I

 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). Consistenttesting 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.

Comments:
EPA and many states require detection of 1/8 inch (0.32 cm) of product for groundwater
monitoring.
Detectors are listed as interstitial due to intended use.
Test procedures used were a combination of EPA's "Standard Test Procedures for Evaluating
Leak Detection Methods: Liquid-Phase Out-of-Tank Product Detectors," March 1990, and EPA's
"Standard Test Procedures for Evaluating Leak Detection Methods: Nonvolumetric Tank Tightness
Testing Methods," March 1990.
Detector is reusable.
Although ENCOMPASS APAM (Accessory Probe Access Module) was not included in evaluations,
according to manufacturer,  probes perform in the same manner when connected to any one of these 3
systems.

 Minimum detectable water level  in the tank is 0.49 inch.
 Minimum detectable water level  change is 0.0052 inch.  .

 Thermistors and probe must be checked and calibrated 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). Consistenttesting 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.
Auto Stik Jr. is used with up to 4 magnetostrictive probes and can handle up to 8
 input sensors.
Auto Stik II is used with up to 16 magnetostrictive probes and can handle up to 64

                    Continuous operation during flowing conditions (however, thresholds are higher due to hydralic
                    noise in pipeline).
                    Declares leak if current changes in pressure exceed tuning parameters, or if pressure
                    fluctuates  in a manner that is characteristic of a leak.
                    Dispensers shutdown, indicator light and  alarm activation if leak is declared. ..

 Calibration:         System must be checked annually. Standard electronic field instruments used by the

Maximum of 15,000 gallons.
Tank must be minimum 90% full.

Minimum of 8 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 average of subsets of all collected data.
There must be no dispensing or delivery during test.

Average for product is determined by a minimum of 5 resistance temperature
detectors (RTDs).

Must be used to detect water ingress.
Minimum detectable water level jn  the tank is 0.83 inch.
Minimum detectable water level change is 0.0116 inch.

RTDs and probe must be checked and calibrated 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). Consistenttesting 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.

Comments:
Test procedures used were modified by evaluator from EPA's "Standard Test Procedures for Evaluating
Leak Detection Methods: Vapor-Phase Out-of-Tank Product Detectors," March 1990.
Detection times were not directly measured.  However, evaluator states, "experiential evidence predicts
that the detector response will reach 'alarm' conditions (30%  of maximum fresh fuel response) at a
distance of 5 meters in slightly over one day."
Each cartridge is used once, then replaced by another.

then the tank cannot be tested using this method.

Load cell must be calibrated before each use.

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 of 3 hours.                                          ,
Test data are acquired and recorded by a computer.
Leak rate is calculated as the average of subsets of all data collected:
There must be no dispensing or delivery during test.

Average for product is determined by a minimum of 5 resistance temperature
detectors (RTDs).                 ;   .  •

Must be used to detect water ingress.
Minimum detectable water level in the tank is 0.41 inch.
Minimum detectable water level change is 0.0013 inch.

Execution of Probe Check diagnostic routine is recommended prior to leak detect
tests to ensure sensor is fully operational and in  calibration.
Annual preventative maintenance should be performed per 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). Consistenttesting 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.

                 NON-VOLUMETRIC TANK TIGHTNESS TEST METHOD (ULLAGE)

 Certification:     Leak rate of 0.1 gph with PD=100%and PFA=0%.

 Leak Threshold:  A system should not be declared .tight when the acoustic signal detected is different
                  from the baseline.
                  Baseline is the acoustic signal before tank is pressurized pr evacuated.

 Applicability:     Gasoline, diesel, aviation fuel, fuel oils #4 and #6,  waste oil, and solvents.     •

 Tank Capacity:   Maximum ullage volumeiis 16,500 gallons.

 Waiting Time:    None between delivery and testing

 Test Period:      A few minutes to determine background noise and a leak.              .'-.-;...
                  Depends on background noise at  the site and on the size of the leak.
                  After the desired pressure has been reached, the tank should be allowed to settle
                  for 10 minutes.
 Test Pressure:
                  Vacuum of 1 psi must be maintained in ullage by a vacuum blower, or total pressure
                  at bottom of tank of 4 psi must be maintained using nitrogen.
Temperature:     Acoustic signal is independent of product temperature.
Groundwater:
                  Depth to groundwater in backfill must be determined. If groundwater is above
                  product level, vacuum test should not be used.
                  Pressure test may only be used if net pressure can be maintained at a
                  minimum 1 psi throughout ullage during test  If this requires more than
                  5 psi total pressure at tank bottom, the ullage test must not be used.
Comments:
                  Not evaluated using manifold tank systems.
                  Evaluated using diesel fuel.
                  Tests only ullage portion of the tank.
                  Product-filled portion of tank must be tested with an underfilled test method.
                  Microphone was 25 feet away from the leak source during evaluation.
                  If background noise is too high, test is inconclusive.
                  Noise signals are tape recorded (not digitally recorded).
                  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.

NON-VOLUMETRIC TANK TIGHTNESS TEST METHOD (ULLAGE)

Leak rate of 0.1 gph with PD=95.24% and PFA=0%.

A system should not be declared tight when the make-up gas flow rate into ullage
equals or exceeds 0.275 cubic feet/hour.

Gasoline, diesel, aviation fuel, heavy fuel oil #4, and solvents.

Maximum ullage volume is 7,500 gallons.

Minimum of 2 hours between delivery and testing.  *

Minimum of 20 minutes, consisting of 2 consecutive 10-minute test periods.
Test data are acquired and recorded manually.

Pressure must be increased in ullage such that total pressure at
bottom of tank does not exceed 5.0 psi.
Pressure must be maintained for a minimum of 5 minutes per 1,000 gallons
of ullage.
At conclusion of this stabilization period, ullage pressure must be reduced by
0.5 psi for remainder of test.

Ullage must be monitored for rate of temperature change, which must not
exceed manufacturer's tabulated values.

Depth to groundwater in backfill must be determined.  If groundwater is above
product level, net pressure must exceed 1  psi in the ullage during test.
If this requires more than 5 psi total pressure at tank bottom, the ullage test must not
be used.

Not evaluated using manifold tank systems.
Evaluated using diesel fuel.
Tests only ullage portion of tank.
Product-filled portion of tank must be tested using a volumetric underfilled test
method.

                NON-VOLUMETRIC TANK TIGHTNESS TEST METHOD (VACUUM)

Certification:    Leak rate of 0.1 gph with PD=100% and PFA=0%.

Leak Threshold: A system should not be declared tight when the acoustic signal detected is different
                from the baseline.
                Baseline is the acoustic signal before tank is evacuated.

Applicability:   Gasoline, diesel, aviation fuel, fuel oils #4, waste oil, and solvents.

Tank Capacity:  Maximum product volume of 30,000 gallons. Tank product level must be between 7
                and 86 inches.

Waiting Time:   None between delivery and testing

Test Period:    A few  minutes to determine background noise and a leak.
                Depends on background noise at the site and on size of leak.

Test Pressure:  Vacuum of 0.5 psi beyond the vacuum required to overcome the tank bottom
                pressure* must be maintained in ullage by a vacuum blower.

Temperature:   Acoustic signal is independent of product temperature.

Groundwater:    Depth to groundwater in backfill must be determined. If groundwater is above
                the tank bottom, this test method may not be used.

Comments:     Not evaluated using manifold tank systems.
                 Evaluated  using diesel fuel.
                Tests  only portion of tank containing product.
                 Ullage portion of tank must be tested with an ullage test method.
                 Microphone was 25 feet away from the leak source during evaluation.
                 If background noise is too high, test is inconclusive.
                 Noise signals are tape recorded (not digitally recorded).
                 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.


*  Net vacuum applied = 0.5 psi  + [inches of product level x the specific gravity of product x 0.036].

 VOLUMETRIC TANK TIGHTNESS TEST METHOD (UNDERFILL)

 Leak rate of 0.1 gph with PD=99.9% and PFA=0.1%.

 0.05 gph. A 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, fuel oils #4 and 3*6, waste oil, solvents, and other
 products.

 Maximum of 18,000 gallons.
 Tank must contain minimum 24 inches of product.

 Must be long enough between delivery and testing to ensure a temperature
 change of less than 0.09 degrees F per hour, typically a minimum of 2 hours.
 There must be no delivery during waiting time.

 Minimum of 2. hours.                          .-;.....
 Test data are acquired and recorded by a computer.
 Leak rate is calculated from average over data window.
 There must be no dispensing or delivery during test.

 Average for product is typically determined by 5 thermistors.
 A minimum of 1 thermistor is required.

 Depth to grourtdwater 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.)

Thermistors must be checked annually and calibrated if necessary.

 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). Consistenttesting 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.

Certification:      Leak rate of 0.1 gph with PD=100% and PFA=0%.

Leak Threshold:   A system should not be declared tight when the acoustic signal detected is different
                   from the baseline.
                   Baseline is the acoustic signal before tank is pressurized or evacuated.

Applicability:      Gasoline, diesel, aviation fuel, fuel oils #4 and #6, waste oil, and solvents.

Tank Capacity:    Maximum ullage volume is 16,500 gallons.

Waiting Time:      None between delivery and testing

Test Period:       A few minutes to determine background noise and a leak.
                   Depends on background  noise at the site and on the size of the leak.
                   After the desired pressure has been reached, the tank should be allowed to settle
                   for 10 minutes.

                   Vacuum of 1 psi must be maintained in ullage by a vacuum blower, or total
                   pressure at bottom of tank of 4 psi must be maintained using nitrogen.

                   Acoustic signal is independent of product temperature.

                   Depth to groundwater in backfill must be determined. If groundwater is above
                   product level,  vacuum test should not be used.
                   Pressure test may only be used if net pressure can be maintained at a minimum
                   1  psi throughout ullage during test.  If this requires more than 5 psi total
                   pressure at tank bottom, the ullage test must not be used.

Comments:        Not evaluated using manifold tank systems.
                   Evaluated using diesel fuel.
                   Tests only ullage portion of the tank.
                   Product-filled portion of tank must be tested with an underfilled test method.
                   Microphone was 25 feet away from the leak source during evaluation.
                   If background noise is too high, test is inconclusive.
                   Noise signals  are tape recorded (not digitally recorded).
                   Vacuum test method may not be effective in some backfill (such  as clay)
                   because it may plug holes in tank.

                    NON-VOLUMETRIC TANK TIGHTNESS TEST METHOD (VACUUM)

Certification:     Leak rate of 0.1 gph  with PD=100%and PFA=0%.

Leak Threshold:  A 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.

Applicability:     Gasoline, diesel, aviation fuel, fuel oil #4, and waste oil.                         -
                 Water miscible 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 or) 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.

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 inch.
                 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.

 There must be no dispensing or delivery during test.

 Average for product is typically determined by 5 thermistors.
 A minimum of 1 thermistor is required.

 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.)

 Thermistors must be checked annually and calibrated if necessary.

 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)^ Consistenttesting 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.

Comments:
       A system should not be declared tight when tracer chemical is detected
       outside of the pipeline.

All fluid petroleum products and any other fluid with which an acceptable
tracer is compatible.

Minimum is normally 2 weeks after injection of the tracer into the tank,  but
must be no less than 1 week, and no more than 4 weeks. For very large systems,
several days or weeks may be required to circulate tracer-labeled fuel through all
parts of the system. Under these circumstances the 1 week waiting time begins
after the tracer reaches the pipeline being tested.

Dosage of tracer is a factor of tank size and frequency of tank refills according to
manufacturer's recommendations.
Tracer labeled product should be circulated through the pipeline before test
period begins.
Pressurized pipeline must be brought up to operating pressure
or operated on a daily basis.

Soil permeability must be sufficient for transport of tracer through backfill
(greater than 1 Darcy).

Radius of influence of each probe is 10 feet.  Locating pipelines should be done
according to manufacturer's operating procedures for pipeline test results to be
valid.

Presence of frozen, saturated soil surrounding the pipeline may limit
effectiveness of test method.
Presence of groundwater surrounding pipeline may also reduce effectiveness of
test method (e.g. when applied to pipelines containing water-miscible products or
products whose specific gravity is greater than 1).
There is no volume lilitation with this method.

 NON-VOLUMETRIC TANK TIGHTNESS TEST METHOD (TRACER)

   Leak rate of 0.1 gph with  PD=100% and PFA=0%.

;   A system should not be declared tight when tracer chemical is detected outside of
   the tank.

   All fluid petroleum products and any other fluid with which an acceptable
   tracer is compatible.

   This test method is not limited by capacity, however only portions of the tank
   system within 10 feet of sample collection point are tested.

   Ranges from 7 to 30 days (generally two weeks) after injection of the tracer into the
   tank.

   Dosage of tracer is a factor of tank size and frequency of tank refills according to
   manufacturer's recommendations.

   Soil permeability must be sufficient for transport of tracer through backfill
   (greater than 1 Darcy).

   Radius of influence of each probe is 10 feet. Probes must be placed such that all
   possible locations and orientations are within the circle of influence.

   Depth to groundwater in backfill must be determined.  In order for a
   leak below groundwater to be indicated by the release of the tracer compound, the
   hydrostatic pressure of product in tank must exceed the hydrostatic pressure of
   groundwater during test. This is done by maintaining product level at least 6
   inches over groundwater for a minimum 17 hours during first three days following
   addition of tracer to tank.
   In high groundwater situations, this method may be supplemented with
   measurement of water ingress, at the discretion of the regulatory agency.

   Presence of frozen, saturated soil above bottom of tank may limit
   effectiveness of test method.
   Presence of groundwater above bottom of tank  may also limit
   effectiveness of test method (e.g. when applied  to tanks containing water-
   misclble products or products whose specific gravity is greater than 1).

gain that equals or exceeds this threshold.

Gasoline, diesel, aviation fuel, fuel oil #4, and solvents.
Other liquids may be tested after consultation with the manufacturer.

Maximum of 2,000,000 gallons. Application of this method for larger tanks is
currently under review to determine correct scalling factors for leak rate, threshold
and test time versus tank size.
Tank must be minimum 90% full.

Water ingress is detected by an increase in total mass of product in the tank.
To monitor water continuously, a separate water sensing probe must be installed.

The mass bouyancy probe must be checked and calibrated 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). Consistenttesting at low levels could allow a leak to remain
undetected.

 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). Consistenttesting 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.

                   Maximum of 45,000 gallons.
                   Tank must be minimum 78.6% full.

                   Minimum for tanks up to 45,000 gallons must be determined from the
                   manufacturer's chart  of "Wait Time versus Tank Volume."  This chart must
                   be included  in the tank test report.

                      System reports a quantitative result of pass or fail.
                      Evaluated using both single and manifold tank systems.
                      System collects data at naturally occurring product levels without interfering with normal tank
                      operation, and discards data  from unstable periods when system performs test.
                      Data can be collected at any level above 12 inches of product.
                      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.
                      Test procedure used was Midwest Research Institute's "Evaluation of Continuous In-Tank Leak
                      Detection Systems," April 17,1995.
                      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.

    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.
    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.
              Place the water sensor flush with the bottom of the probe shaft and place the product float near the
              middle of the probe shaft.
              Check the height reading on the tank gauge monitor (after allowing sufficient time for the monitor to
              respond).
              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.
    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.
    To test the accuracy of the water sensor:
              Remove  probe from the tank.
              By hand, move the water float up the probe to a point higher than the high-water alarm set point.
              The monitor should respond with a high water alarm report.  (The water height may also appear on the
              tank monitor display console.
         u.   Check this height against its  actual location.
     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.
        c.   The monitor should respond with a high water alarm. (The water height may also appear on the tank
            monitor display console.)
        d.   Check this height against its actual location.

4.   The high water level alarm should not be set so high that water ingress into the tank goes undetected for long
    periods of time.

APPENDIX
GLOSSARY OF TERMS

Accuracy:
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.

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 consistantly 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 Systems (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 and 5% probability of false alarm.
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 Systems (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 deliverry receipts, for example.

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.

False Alarm:
Declaring a tank to be leaking when in fact it is tight.
                                                358

 GLOSSARY OF TERMS CONTINUED

 Groundwater:
 Water table or water within the excavation around a tank.

 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:
 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.

 Lag Time:
 The elapsed time from the detector's first contact with test product to the first detectable signal.

 Leak threshold:
 The measured leak rate at which the test method detects 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 methods given in 40 CFR
 § 280 Subpart D-Release 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 method.

 Manifold 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.

 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. 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.

 MER:                 '              .  •        '"  '    ' .  \   ,   "     '

 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
method. It is a positive number expressed in gallons per hour (gph).
                                                359

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.

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
