Why You Should  Read This Booklet

Federal and state laws require underground storage tank systems (USTs) to
have leak detection. One of the available leak detection methods is Statistical
Inventory Reconciliation (SIR). In this method, a trained professional uses
sophisticated computer software to conduct a statistical analysis of inventory,
delivery, and dispensing data.

SIR can allow the owner or operator of an LIST facility to meet leak detection
requirements without an extensive outlay of capital, using only the equipment
that most facilities have readily at hand—a tank stick and a tank chart used for
inventory control. The SIR analysis itself is usually provided as a service by
vendors who charge a monthly fee based on the number of tanks.

This booklet provides basic information on the method—what it is, how it works,
factors that impact data quality—to assist you in determining if SIR is
appropriate to your needs.

If you need information on federal leak detection requirements and the various
methods of leak detection available to you, see Straight Talk on Tanks. For a
free copy, call the U.S. Environmental Protection Agency's (EPA's) toll-free
Hotline at 800 424-9346 and ask for publication EPA 510-K-95-003.

                                Introduction To SIR  1

-------
 To many people, SIR
 may seem like magic.
 But it's based on sound
 mathematical principles.
A 'FAIL' does not
necessarily mean
your system is
leaking, but you
must still notify
your local LIST
agency.
How Does SIR Work?

On the face of it, SIR looks very similar to old-fashioned inventory control—the
owner or operator, using simple equipment, tracks tank volumes, deliveries,
and sales. However, the similarity ends there. Simple inventory control is
relatively imprecise.  Depending on your system throughput, you could be losing
hundreds of gallons  every month without realizing anything is wrong!

By contrast, SIR analysis can be very sensitive and accurate. A SIR vendor can
take the same inventory data and analyze them for releases so small that many
would go unnoticed with inventory control. By using a month's worth of good
tank data,  it is possible for SIR methods to detect a release of just over 11/4
pints per hour (that's about 145 gallons per month) from a tank or its product
lines 95 times out of a hundred.

The mechanics  of how SIR works are beyond the scope of this booklet. SIR
vendors actually use a variety of statistical tools to evaluate inventory  data, and
no two vendors' methods are exactly alike—the information they collect and the
results they provide can vary. Still, for fundamental release detection purposes,
there are only three possible bottom-line responses for any SIR test: PASS,
FAIL, or INCONCLUSIVE. These bottom-line responses are described below and
on the following pages.

PASS—According to the analyzed data, the LIST system tests tight.

FAIL—Analyzed data indicate a loss of product from the system or an  influx of
groundwater.  However, a FAIL does  not necessarily indicate that your system is
leaking. A  FAIL may indicate miscalibrated dispensers, inaccurately metered
deliveries,  or stolen product. There is also a chance that a FAIL is a false alarm.
If you receive a FAIL, you must first notify your local LIST regulatory
agency. Then, you should explore possible reasons for the FAIL (see page 7).
Keep your local LIST agency informed as to your findings.

INCONCLUSIVE—Analyzed data cannot make the  call. There is a chance that the
information provided to the SIR vendor is so bad that it is not possible to make
a determination. This often can be traced back to poor tank sticking or
bookkeeping practices (for example, a new hire who has received inadequate
training). Whatever the reason, an INCONCLUSIVE result means, in effect, that
you have failed  to perform leak detection on the  LIST in question for that
month. You are in violation of federal leak detection  requirements. Contact your
state LIST  program office to find out local policy on how INCONCLUSIVE results
are handled. See page 7 for additional information.
                                       Introduction To SIR  2

-------
Necessary  Equipment

One of the major attractions of SIR for LIST owners and operators is that it
does not require a large, up-front investment of capital—the primary cost is
subscribing to the SIR vendor's services. The equipment needed to use the
method is usually already found on-site at most LIST facilities.
Gauge Stick Or Other Gauges

A gauge stick, made of wood or other non-sparking material, is used to
measure the depth of liquid in the LIST. Typically, such sticks are marked or
notched in 1/8-inch increments starting with the bottom of the stick. It is
important that the stick be in good condition. Sticks that have worn ends, cut-
off ends, worn-off numbers, or worn-off varnish coatings are not acceptable
and should be replaced.

Other forms of gauges can also be used if they are available and in good
operating condition. Automatic tank gauges, for instance, can simplify
measuring tank volumes. (Keep in mind, of course, that some automatic tank
gauging systems can serve as acceptable monthly tank leak detection methods
by themselves.)

Whatever form of gauge you choose to use, you must follow the SIR vendor's
instructions carefully to gather useful data. For instance, many providers of SIR
services require that the tank measurements are made to the nearest 1/8-inch.
If you fail to follow the vendor's instructions,  you may end up with inconclusive
test results.
Good sticking practices
are essential to good SIR
analyses.
Pastes For Finding Fuel Or Water

If you use a gauge stick, you can improve the quality of your readings if you
use a fuel-sensitive paste smeared over about six inches of the stick where you
expect the fuel level to be. The paste changes color where it comes into
contact with the fuel.

Similarly, you can use a water-sensitive paste on the end of the stick to monitor
for the presence of water in the bottom of the tank. While water in the tank can
come with your deliveries or as a result of condensation of moisture inside the
tank, it can also come from groundwater leaking in through holes or through
loose fittings high in your tank.

Tank Chart

The strapping chart used to convert stick measurements into gallons must be
the right one for the tank. The chart should have stick measurements listed to
1/8 of an inch to minimize math errors that occur when using charts marked off
to the nearest inch. SIR vendors can quickly determine  if the chart is
inappropriate to your tank, and will often generate a proper one for your tank.
                                Introduction To SIR  3

-------
Calibrated Dispensing Meters
A poorly calibrated totalizer can produce bad data that may be mistaken for
some types of releases. While many SIR vendors can identify this pattern as a
possible cause of a FAIL, it is wise to avoid the problem entirely. Keep your
dispensers in good operating condition and have them periodically recalibrated
as recommended by your equipment manufacturer and as required by state
and local weights and measures agencies.

Forms
The SIR vendor typically provides forms on which daily stick readings, sales,
and deliveries are recorded. These forms often resemble the inventory sheets
usually maintained at LIST facilities. In some instances, SIR vendors may allow
submission of the data on a facility's own  inventory sheets. Some vendors may
also permit submission of data in electronic format, such as computer
spreadsheets.
SIR Reporting And  Recordkeeping

What You Should Provide To The Vendor
Although SIR vendors may ask for a variety of information, some of the more
common elements include:

•  Tank size (capacity, diameter, and length).
•  Tank type, material of construction, and manufacturer.
•  Product type.
•  Date each stick measurement was taken.
•  Daily opening stick measurement and volume.
•  Daily closing stick  measurement and volume.
•  Daily sales volume.
•  Gross deliveries over the course of the  month.
•  Thirty days of observations.

What The Vendor Should Provide To You
Vendors supply different levels of service to their clients. You will need to
consult with individual vendors to find the collection of features you desire.
However, there is a core of reporting elements that should be common to all
SIR analyses (see sample on page 6). These include:
              Introduction To SIR  4

-------
•  Clear and timely reporting of results in terms of PASS, FAIL, or
   INCONCLUSIVE.

•  Complete and annotated copies of inventory records used in the analysis,
   showing such problems as errors in delivery records or bad measurements
   tossed out by the test.

•  Suggestions as to the likely cause of any test failure or inconclusive result.

•  Instructions on follow-up actions to be taken in the event of a FAIL or
   INCONCLUSIVE (for example: "Notify your local LIST agency of a failed test
   result within 24 hours").

Also, in the case of quantitative testing methods, the form should report the
calculated leak rate in gallons per hour and the leak threshold at which a leak
would be declared based on the data provided for each tank. The minimum
detectable leak rate (MDL) for your data may also be provided by some
vendors. (See page 9.)

Your SIR vendor may also supply you with other useful information and
services beyond  the basics itemized above. SIR vendors may further provide:

•  Off-site storage of leak detection records.
•  Potential reasons for a FAIL other than a release of product:
   ^  Apparent product theft
   ^  Missed product delivery entry
   ^  Suspected totalizer miscalibration
•  Potential reasons and possible solutions for any INCONCLUSIVE results.
•  Possible location of leak within the system.
•  Assessment of tank sticking practices.
•  Special tank-specific  strapping charts for those tanks needing them (such
   as tilted tanks and odd-sized tanks).

What You Should Keep On File
The minimal recordkeeping requirements for facilities using SIR are the same
as for other release detection methods:

•  All written performance claims pertaining to the SIR method used and the
   manner in which those claims were justified or tested by the vendor (such
   as a third-party evaluation of the method) must be kept on file for five years
   from the date you started using the method at the facility.

•  The monthly SIR reports, along with the results of any other sampling,
   testing, or monitoring, must be kept for at least one year.

-------
•  Records of equipment calibration and maintenance must be kept for at
   least one year. Any schedules of required calibration and maintenance
   provided by the SIR vendor must be kept for five years from the date you
   began using the method at the facility.

You should check with your local LIST agency to determine if there are any
additional recordkeeping requirements.

What To  Do When You Get A 'FAIL'
When your LIST system fails a SIR monthly analysis, you must report the
incident to your local LIST program agency within 24 hours or whatever time
period your local agency requires.

At the same time, you need to begin to investigate the cause of the failed test.
Within seven days, you must determine the cause  of the FAIL and report back
to your local agency. Your SIR vendor may, on the basis of the test results, be
able to provide you with areas to examine, such as a miscalibrated totalizer.
You must have any defective equipment repaired or replaced immediately.

If the FAIL cannot be linked to equipment problems, you must have the system
tightness tested or the site checked for evidence of a release (such as
sampling in the excavation zone). You must report the results to the local
agency. If a release is confirmed, the agency will provide instructions for any
necessary cleanup action.

What To  Do When You Get An 'INCONCLUSIVE'
An INCONCLUSIVE means you have failed to meet leak detection requirements.
However, the steps you must take upon getting an INCONCLUSIVE depend on
the requirements of your local LIST agency. In some instances, you may be
required to perform a system tightness test to be sure the LIST is not leaking.
In others, you may be given an additional month to come into compliance. Be
sure to know what is required locally. A list of LIST agency phone numbers can
be found  in the back of this booklet.

An INCONCLUSIVE should in no way be taken as demonstrating the failings of a
given vendor's method—it is inherent to all methods.  Even if vendors use
terms other than "inconclusive," they represent the same condition.

In all cases, you will want to double  check your operating procedures to see
what caused the INCONCLUSIVE and  prevent its recurrence. Your SIR vendor will
provide assistance in locating the problem and offer suggestions to improve
your data collection.
    HELP!
An 'INCONCLUSIVE'
means that you
effectively have no
leak detection for
that month.

                       Answers To Frequently Asked Questions
                        "Can SIR be used on manifolded tanks?"
                        SIR methods can be used on tank systems that have multiple tanks linked
                        together by siphon bars. This generally requires that each tank in the
                        manifolded system be individually stuck for inventory measurements. As with
                        single tank systems, no product deliveries or sales should be made during the
                        time the sticking and totalizer readings are taking place.

                        Check with your local LIST agency to determine if it permits use of SIR on
                        manifolded systems or has additional requirements.
                        "Can SIR be used as an annual tightness test?"
                        For facilities that are still using inventory control with tightness testing as their
                        means of leak detection, it is possible to use SIR in place of more traditional
                        tightness tests such as an overfill test. The performance requirements for a
                        tightness test are more stringent than for monthly monitoring methods,
                        however, so be  sure to check that your SIR vendor can meet those
                        requirements. Tanks must be tested for releases of 0.1 gph with a probability of
                        detection (PD) of 95% and a probability of false alarm (PFA) of 5%. To act as a
                        replacement for piping tightness testing, the requirements are even more
                        rigorous—the SIR method must be able to detect releases of 0.08 gph with a
                        PD of 95% and a PFA of 5%. To find releases of this magnitude, SIR vendors
                        often need several months of good data.

                        Be sure to contact your local LIST agency to see if it allows use of SIR as an
                        annual test. Also, remember that inventory control with tightness testing can
                        only be used for a limited time. You may want to consider moving now to an
                        approved method of monthly monitoring, such as automatic tank gauge
                        systems,  monitoring wells, or monthly SIR analyses.
There is no such
thing as an
"acceptable" leak.
Any leak will cost
you in the long run
and should be
fixed.
"Why did a SIR vendor fail my tank for a leak under 0.2 gph?"
First of all, it is a misconception that any leakage into the environment is
acceptable. Even small leaks over long periods of time can result in extensive
contamination that can cost you substantial time and money for soil and
groundwater clean up.

Secondly, the performance standard by which leak detection methods
(including SIR) are measured says that leaks of 0.2 gph must be detected in 95
out of 100 times. Further, false alarms should not happen more than five times
in a hundred. What this means is that the SIR vendor looks at the estimated
leak rate determined for a tank—say 0.15 gph—and asks the question "What is
the likelihood that the true leak rate is actually 0.2 gph?" On the basis of a
statistical analysis of the data you provide the vendor, the SIR vendor can
make  the call as to whether your system tests tight or not.
                                      Introduction To SIR  8

-------
Typically, a FAIL will be called for apparent releases of around 0.1 gph. See the
question on page 10 on 'estimated leak,' 'threshold,' and 'MDL' for additional
information.
"What is the difference between 'qualitative' and 'quantitative' SIR
methods?"
Although there are many methods that are employed by vendors performing
SIR analyses, they break down into two major classifications: qualitative and
quantitative.

Qualitative methods do not provide estimated leak rates. When a vendor's
qualitative method is evaluated to demonstrate its capability of meeting the
EPA performance standard, it simply reports results in terms of PASS, FAIL, or
INCONCLUSIVE. These results are compared with the evaluator's knowledge of
which tanks are leaking in a test set of tank records.

Quantitative methods also categorize results in terms of PASS, FAIL, or
INCONCLUSIVE, but they go further by actually providing a numerical estimate of
the leak rate, typically in gallons per hour. In evaluating the performance of the
method, the evaluator compares  the method's estimates with the actual  leak
rates imposed on the test set of tank records.
NOTE: EPA neither
certifies nor
approves any leak
detection vendor
or method. Method
evaluations are
generally done by
third-party testing
organizations.
"What is this 'estimated leak rate,' 'threshold,' and 'MDL' stuff all about?"

These are rather technical statistical terms often used by quantitative SIR
vendors to provide their clients with more detailed information on their
analyses. They provide insight beyond the simple PASS, FAIL, and
INCONCLUSIVE, including just how bad a leak appears to be (estimated leak
rate) and how good the data are that you have been providing to the vendor for
analysis (MDL).

The estimated leak rate is the number a quantitative SIR method comes up
with for the amount of product your tank appears to be losing. The number is
usually expressed in gallons per hour since the EPA regulations use those
units.

This  estimated leak rate is rarely, if ever, zero. All tanks, whether leaking or
tight, will generally show a leak rate. The question is, is this leak rate
significant? This is where the threshold comes in.

The threshold is basically an action level leak rate. That is, if the estimated
leak  rate exceeds the threshold leak rate, the SIR vendor declares a FAIL. It is
important to note that the threshold is not a fixed number, such as 0.1 gph.
Instead, it is typically the value associated with a fixed percentage set to the
probability of false alarms (that is, declaring a leak on a system that is actually
tight) the SIR vendor is willing to accept. EPA's regulations allow no more than
5% of analyses to turn out to  be false alarms. However, many SIR vendors
consider one failure in twenty analyses to be too high and set their thresholds
to a 1% probability of false alarm.
 SIR vendors offer
 a diverse number
 of supplemental
 reporting options.
 Look over what
 each has to offer
 and choose the
 one that best
 meets your
 needs.
                                Introduction To SIR  9

-------
NOTE: State
programs may
require a different
form of testing for
lines. Check with
your local UST
agency.
Finally, the MDL is the Minimum Detectable Leak. The MDL is the smallest
leak rate the vendor can determine for the data provided with a PD of 95% or
better. The MDL is tied to the threshold and is usually twice the threshold leak
rate. The MDL must be less than or equal to the EPA performance standard
rate of 0.2 gph at a PD of 95% and a PFA of 5% in order to make a PASS/FAIL
call. If the MDL exceeds the performance standard, your system cannot be
given a PASS—an INCONCLUSIVE is the best you can get.

Fortunately, most vendors who provide this level of detail often provide a "plain
English" translation as well.

"Can SIR be used as a monthly test of my piping, too?"
Yes. SIR is a test of the entire UST system. Losses are reported regardless of
their origins.  So, whether you are losing product as a result of a tank leak, a
line leak, miscalibrated equipment, or theft, a FAIL will result if the estimated
leak rate exceeds the threshold for calling a leak. Remember, though, that if
you are using pressurized  lines, you will also need to have an automatic flow
restrictor, shutoff device, or continuous alarm in place to fully meet piping leak
detection requirements.

"How much  does SIR cost?"
Unlike most other methods, SIR has no  installation costs and equipment costs
are minimal—a well-calibrated dispensing meter and a good stick are about all
you need. While vendor costs will vary, monthly monitoring for a facility with
three USTs costs about $800 to $1200 per year. SIR used as an annual
tightness test costs about $200 to $600. (These figures are based on estimates
in 1995.)

"There are so many vendors. How do I choose?"
Whether you have decided to invest in SIR services or other leak detection
methods, the basic steps are similar:

•   Request information from the vendors you are interested in. Compare their
    services, option packages, and prices to see which vendors best meet your
    needs. Ask for references and check them.

•   Contact your local UST agency to see if it has a certification program for
    leak detection vendors. Consult the agency's list of certified service
    providers.

•   Contact the Better Business Bureau to see if there have been any
    complaints lodged against the vendor.
