Is  Leak  Detection  Working?

                                      many an UST regulator that every tank
                                      leaks...more than a drop. In reality, some USTs
                                      are leaking and some are not. The question is:
                                      "How do we distinguish between USTs that
                                      are tight and USTs that are leaking?"

                                         The notion that there should be leak detection
                                       for USTs is not new. The 1913 edition of the
                                      National Fire Prevention Association's NFPA 30
                                      suggests that "test wells" be installed adjacent to
                                      tanks to detect leaks. By 1941, NFPA was recom-
                                      mending periodic testing of older tanks. In 1951, the
                                      American Petroleum Institute published the first edi-
                                     tion of its recommended practices for inventory

• Is Leak Detection Working?
from page 2	
     The Petro-tite tank tester can
trace it's heritage to tike 1950s, when
Fred McLean  set  out  to  find  a
method of tank testing that was safer
than air pressure and more reliable
than   standpipe   testing.   Mr.
McLean's research came to fruition
with the "Kent-Moore" tank tester
which became commercially avail-
able  in the mid-1960s and was
renamed Petro-Tite in the early '80s
when the rights to the equipment
were sold.
     But, while an awareness of the
issue of leak detection for USTs has
been long-standing, that awareness
has not routinely been followed by
effective action to detect or prevent
leaks. NFPA's idea back in 1913 for
test wells never took root. By 1941,
the association  was struggling to
deal with increasingly large numbers
of leakers that were creating fire and
safety hazards. In the  1960s, the
petroleum marketing trade press
documents an increasing awareness
of the leakage problem, but by 1979
the headlines still read, "Tank Leaks:
Like the Common Cold, Nobody's
Found a Cure."
     By 1982, estimates based on
petroleum industry  studies  indi-

cated that there were 50,000 to 70,000
actively leaking USTs and that 30
percent of installed tanks were leak-
ing, or would leak  within the next
few years. Finally, in 1984, the fed-
eral government stepped in, and the
Subtitle  I  amendments  to  the
Resource Conservation and  Recov-
ery Act became the  law of the land.
Four years later, EPA  regulations
governing USTs went into effect. By
March of 1997, 329,000 confirmed
releases had been reported.

The Leak Detection
Conundrum
The federal UST program, estab-
lished in 1988, is primarily a leak
detection, not a leak prevention, pro-
gram.  While some  emphasis is
placed on leak prevention through
corrosion protection, a regulatory
program truly designed to prevent
releases  would include secondary
containment for all storage tanks
and piping. Secondary containment
is the only UST technology that is
forgiving of human error  in  the
installation and operation of  storage
systems. This is because monitoring
of secondary containment generally
provides a significant delay between
the onset of a leak and the release of
product to the environment.
     In  a  recent  case in  Maine,
months and perhaps years elapsed
between the time  a pry bar was
dropped to the bottom of a fiberglass
double-walled tank, causing  a small
fracture in the primary tank, and the
time a routine state inspection  dis-
covered that the interstitial monitor-
ing probe had been disconnected.
The tank interstitial space was half
full of product, but there was  no con-
tamination associated with this inci-
dent and no cleanup was required.
     Leak detection methods other
than interstitial monitoring are based
on the game of "catch me if you can,"
where the leaks we seek to catch are
technologically elusive, and many
UST operators are somewhat reluc-
tant leak seekers. All too often, fail-
ure to take the game seriously results
in a large release of product to the
environment.

The Nagging Questions
I have two nagging questions about
leak detection:     ;
*•  Does leak detection work? (Is the
   technology up to the task of iden-
   tifying leaks in a timely fashion?)
^-  Where leak detection  fails, is it
   due to:
   -  Inadequacy of the method?
   -  Inadequate  execution of  the
     method by owner/operator?
   -  Absence of leak detection alto-
     gether?
     The anecdotal evidence with
regard to whether leak detection reli-
ably works is not convincing.  For
instance:
K  I  recently  reviewed  inventory
   records for a facility that indicated
   a loss rate of 20 percent of sales
   (nearly 3,000 gallons per month!)
   for 4 consecutive months. There
   was  no  response from  anyone
   until product appeared in a neigh-
   boring basement.
>•  Data from California  regarding
   the percentages of SIR analyses
   that reach pass / fail / inconclusive
   results indicate that there are sig-
   nificant inconsistencies among the
   methodologies used by SIR ven-
   dors.
>•  Although the state  initially  put
   great faith in groundwater and
   soil vapor  monitoring for leak
   detection, Florida has found that
   these leak detection methods are
   severely  compromised by pre-
   existing  contamination  and is
   moving  toward universal sec-
   ondary containment.
^-  I hear frequent reports of failed
   tank  tightness tests that are rou-
   tinely followed by passing results
   using another tank  test method.
^  Automatic tank gauges (ATGs)
   that  conduct tests  every  night

                                                                                           LUSTLine Bulletin 26
  sound like a good idea, but the
  occasional failed test result that
  almost inevitably  results  intro-
  duces an element of  confusion
  and doubt to the technology.
> A California survey of leak inci-
  dents indicated that a great many
  newly  reported  releases  were
  located at facilities where no rou-
  tine leak detection was conducted.

No Room For Complacency
We cannot afford to be complacent
with regard to leak detection, because
regulatory programs in  almost  all
states permit single-walled tanks and
piping to stay in the ground until a
leak is detected. In my more cynical
moments, it seems to me that this
approach grants every storage system
a "right to leak" and ensures that no
storage system  shall be removed
before its time. The combination of
single-walled  storage technology
with the "right to leak" replacement
approach places a  critical emphasis
on effective leak detection.
     It is important that leak detection
be effective for a number of reasons:
^ We are seeing the increasing use
  of reformulated  gasoline contain-
  ing methyl tertiary butyl  ether
  (MTBE). Relative to other gasoline
  constituents, MTBE is very soluble
  in water, and its contamination
  plumes tend to travel farther and
  faster than BTEX plumes. MTBE is
  also more difficult and,  thus, more
  expensive  to  remove  from  the
  environment than the traditional
  constituents of gasoline.
^- As the tank population ages, the
  probability  of leakage increases.
>• The failure of leak detection can
  lead to serious threats to human
  health and the environment
>• Reliance on ineffective leak detec-
  tion can lull UST owners and reg-
  ulators  into  a   false  sense  of
  security
^ Owners/operators may be  wast-
  ing money on  ineffective leak
  detection technology.

What's Working,
What's Not?
So how can we find out  what is
really going on with leak  detection?
In my mind, the only true test of
whether a storage system is tight or
leaking is  to  dig it up. Seeing is
believing. If the tank excavation, pip-
ing trenches, and dispenser islands
are clean, the storage system is tight.
If there is  contamination, then we
can assume that either there is a leak
or there have been leaks or sloppy
housekeeping in the past.
     Between now and the end of
1998, we have a great opportunity to
make just  such observations  with
respect to the large number of stor-
age systems that will be removed in
this time period. All of these systems
should have some form of leak detec-
tion in place. The removal of these
systems presents an ideal opportu-
nity to compare the evidence of the
excavation against the method of
leak detection to see what stories can
be told.
 iftam an environmental protection
 perspective, today's tank population 1
 jjjjyerjfil Is probably the healthiest
      it has ever been. But that is not
            iereareno more leaking
              1we will ever get to a
  TfidJnt where all UST systems are
     Here's my proposal. Although
effective leak detection is primarily
of interest to the UST side of the pro-
gram, enlist the help of those on the
LUST side  of the program who are
often present  at  storage  system
removals (or even private sector tank
removal or site assessment personnel
if they are willing).
     Develop  a standard form to
document tank removal results. Per-
tinent data might include:
> Is there contamination?
^- If contamination is present, is the
  likely source overfilling, former
  USTs, past practices, or the system
  currently being removed?
^ If the source of contamination
  appears  to  be  the  presently
  installed system:
    - Is the source of active leakage
     from tanks, or piping, or both?
    - Is the source of active leakage
     corrosion, leaking fittings, poor
     installation?
    - What is the apparent magni-
     tude  of  the release? (minor,
     moderate, gross)
    - What method of leak detection
     was practiced?
    - Was the method of leak detec-
     tion practiced  properly?  (To
     answer this question, gather
     recent leak detection documen-
     tation, such as a few months of
     inventory,   the  most recent
     tightness test results, the  last
     few months of ATG results, the
     last few months of SIR results.)
Gather the survey forms  and sup-
porting material and forward them
to a central clearinghouse for analy-
sis by knowledgeable people.
     Such a survey would of course
be imprecise because tank removals
are hardly archeological digs,  and
the detective work needed to posi-
tively identify the source of leakage
may not be feasible. In addition, the
people completing the survey forms
will have different points of view,
levels of knowledge and experience,
and powers of observation. Still, if
enough  data  are gathered, some
trends should emerge.

Tweaking USTs For The
Next Millennium
Hopefully, such data should help us
answer the question: Is leak detec-
tion working, and if not, why not?
What we learn could help determine
the direction of the UST program
into the next millennium:
^-  Do we need a rule change or mod-
   ification to eliminate certain types
   of leak  detection, or to change
   how they are executed?
^-  Do we need to focus on education
   of owner/operators to promote
   the correct use of leak detection
   methods?
>  Do we need increased enforce-
   ment to convince recalcitrant own-
   ers that leak detection is a must?

     Are we doing any better in the
realm of leak detection in 1997 than
we were in 1913,1941,1951 or 1984?
From an environmental protection
perspective, today's tank population,
overall, is  probably the healthiest
that it has ever been. But that is not
to say that there are no more leaking
USTs, nor that we will ever get  to a

      Leak Prevention
 New  Protocol  Available for
 Determining Applicability
 of SIR  Methods for
 Manifolded Tanks
       Manifolded tank systems rep-
       resent a significant portion
       of the underground storage
tank population. Many statistical
inventory reconciliation (SIR) ven-
dors feel that their systems are capa-
ble  of  detecting  leaks   from
manifolded systems. The SIR Sub-
committee of the National Work
Group  on  Leak Detection Evalua-
tions (NWGLDE), however, found
that some  SIR methods had been
evaluated  using data from mani-
folded  systems, but that other SIR
methods had been evaluated using
data from non-manifolded systems.
    The Environmental Protection
Agency's (EPA's) Standard Test Proce-
dure for Evaluating Leak  Detection
Methods: Statistical Inventory Reconcil-
iation Methods (June 1990) provides
no guidance on evaluating SIR per-
formance on manifolded systems.
For this   reason,  the NWGLDE
formed an ad hoc  committee to
develop a modified protocol that
establishes such guidelines. Mem-
bers of this committee were Lamar
Bradley, Beth DeHaas, Bill Faggart,
Jerry Fiora, Mike Kadri, Aaron Ram-
bach, and Ken Wilcox.
    The result of this group's work
is the Protocol for Determining Applica-
bility of SIR Methods For Manifolded
Tanks And Determining Size Limita-
tions, developed to ensure that SIR
methods can perform adequately on
both single- and manifold-type tank
systems. This  protocol may not
require any further analysis of data
sets by a vendor. It will, however,
require additional analysis  of test
results by an evaluator to determine
if a SIR method performs adequately
on both single and manifolded tank
systems. It requires analysis of test
results to determine if a method per-
forms better on smaller tanks. It also
explains how to calculate maximum
tank size limits for single and mani-
folded tank systems.
    This protocol was reviewed
and approved by the NWGLDE on
September 27,1996. Please be aware
that this is not an "EPA approved"
protocol; it is a protocol addendum
approved by the NWGLDE.  The
work group also voted to allow only
systems that had been evaluated
according this protocol to be listed
on its "List of Leak Detection Evalua-
tions" as having been evaluated for
manifolded   systems  using   an
approved protocol.

using this protocol, or including a
SIR method on the " List of Leak
Detection Evaluations," please call

 Contractor Associations: A  Network  of Experience
     Since the early 1990s, petroleum equipment con-
     tractors have been establishing state associations
     to deal with underground storage tank issues
 and to work with environmental regulators on devel-
 oping certification and licensing programs.
     The concept or idea of state associations of and
 for petroleum equipment contractors is not new. The
 first petroleum equipment state contractor association
 was chartered in 1955 in New Jersey. In August 1991,
 only six state petroleum equipment contractor associ-
 ations existed. Today, there are 22 state associations in
 Alabama, California, Florida, Georgia, Illinois, Indi-
 ana, Iowa, Kansas, Kentucky, Louisiana, Maryland,
 Missouri, New Jersey, New York, North Carolina,
 Ohio, Pennsylvania, Tennessee, Texas, Utah, Virginia,
 and Wisconsin. Efforts are  underway to organize
 associations in Idaho, Michigan, Minnesota, Nevada,
 and South Carolina. Petroleum equipment contractor
 associations also exist in the provinces of Alberta and
 Manitoba, Canada, as well as London, England, and
 Victoria, Australia.
     These organizations came into being for a vari-
 ety of reasons. Some were formed to communicate to
 their members what was happening in the industry. A
 few were organized to provide management educa-
 tion for company owners. Others were created to pro-
 vide technical training to member firms and their
 employees. A number of organizations took the edu-
 cation theme a step further and were established to
 deal with certification and  licensing issues; some
 developed voluntary certification programs for their
 membership. And  yes,  a few organizations were
 formed to provide lobbying efforts, on behalf of their
 members, for issues related to the industry.
     The successful state contractor associations in
 this industry are productive and prosperous because
 of the commitment and leadership of dedicated asso-
 ciation members who are willing to serve as officers
 and directors. The success of these associations lies in
 the commitment of individuals to the cause—to pro-
 mote high professional standards for individuals and
 companies in the petroleum equipment contracting
 industry.
     The installation, maintenance, and service of
 petroleum storage systems is a specialized field  that
 requires practical experience, combined with careful
 adherence to recognized good practices and proce-
 dures. Petroleum equipment contracting professionals
have worked hard to provide financially sound and
 cost-effective installations, to improve the quality of
workmanship, to ensure that petroleum storage  sys-
tems are installed and maintained correctly, and, ulti-
 mately, to contribute to a cleaner, safer environment.

 Association Goals
 Petroleum equipment contractor associations pro-
 mote their profession with a code of ethics, and they
 address their purpose in the association's bylaws.
 Here is a sample of association objectives as stated in
 a set of bylaws:
 ^- To advance the professional competence of mem-
   bers through the dissemination of information
   related to technical developments, regulations,
   training, and codes, all pertaining to the installa-
   tion and maintenance of petroleum product facili-
   ties.
 >• To  promote  improvement in the environment,
   through programs calculated to reduce contamina-
   tion of soil, groundwater,  and air as a result of
   releases and emissions from petroleum product
   facilities.
 >• To  elevate the  professional level of persons
   engaged in the installation of petroleum product
   storage systems, through the development of vol-
   untary or mandatory licensing, or  certification
   requirements for contracts engaged in such work.
 > To encourage the adoption of laws and regulations
   that recognize the environmental importance of
   responsible tank-system contractors.
 >• To enhance the performance of member firms,
   through the development of a code of ethics for
   companies engaged in the installation and mainte-
   nance of petroleum product facilities, and through
   encouragement of adherence to the code.
 > To cooperate with regulatory agencies and petro-
   leum marketers in the preparation and refinement
   of rules related to the safety,  accuracy, and envi-
   ronmental soundness of facilities installed within
   the state for the storage, measurement, transport,
   and dispensing of petroleum products.
 >• To promote, in all lawful ways commensurate with
   public interest, the business development, and eco-
   nomic welfare of members of the association.
     By setting professional  standards, both cus-
 tomers and end-users stand to benefit. A contractor
 who belongs to an industry-related organization may
be preferred by  a customer over  a nonmember
because he or she is typically better trained, more
 qualified, more knowledgeable, and can generally
better serve a whole range of clients—service stations,
c-stores, major oil companies, private and govern-
ment fleets, and the public.

       Contractor associations stay on the cutting edge
   of new environmental regulations that might be intro-
   duced. Some  states have continuing  education
   requirements for each licensing renewal period. Asso-
   ciations are able to provide technical training and
   education in the latest technologies and procedures. A
   number of associations conduct quarterly educational
   seminars for licensed or certified petroleum equip-
   ment contractors.

   Networking and Communication
   One of the most vital services state petroleum contrac-
   tor associations provide to their members is commu-
   nication. Considered by most members as the most
   important function of the association, effective com-
   munication makes for a successful association. Mem-
   bers of petroleum equipment contractor associations
   are busy and rely on the association to keep them
   informed  of pressing legislative issues, program
   availability, and many industry-related topics. Asso-
   ciations attempt to keep up with the communications
   technology curve and assist members by dealing with
   the  information overload. Organizations provide
   timely and  effective  communications through
   newsletters, data bulletins, e-mail, correspondence,
   faxes, and phone calls.
        While association members oftentimes compete
   with one another, they also benefit from the opportu-
   nity to network with each other within the associa-
   tion. They give and get feedback,  exchange ideas,
   share product information and general business tips
   with others in the field.
        With 22 petroleum equipment contractor associ-
   ations in the country, a national contractor association
   network  has developed under the auspices of the
   Petroleum Equipment Institute (PEI). PEI provides
   the associations with  training opportunities and
   brings together association staff twice a year to share
   ideas, develop programs, discuss problems, and set
   direction for their various organizations. As it usually
   turns out, problems in the industry tend to not be
   unique.
        Through the network, if association members
   need help or information from their organization,
   their staff person now has any number of other
   avenues of resources to turn  to for assistance. This
   network extends to the environmental community as
   well. Association members and staff stand ready and
   are available to serve as consultants and educational
   seminar leaders to environmental regulators, code
   administrators, and fire officials.

   PEI's Role
   The Petroleum Equipment Institute (PEI) has been
   actively involved with petroleum equipment contrac-
tor associations for about 7 years, providing assis-
tance where needed. PEI has been instrumental in
organizing 14 associations and is currently working
with 4 more states to form organizations. Petroleum
equipment contractor associations provide services
and fill a niche that PEI cannot address.
     When new associations are in the process of
forming, PEI assists them with determining and set-
ting up their organizational structure. PEI provides
them with sample bylaws, agenda,  membership
applications, codes of  ethics, budgets, mission state-
ments, and antitrust policy statements. Membership
rosters, dues and budgets,  meetings, officers and
directors,  committees, and a number of operational
considerations are all addressed.
      PEI provides assistance in promoting and orga-
nizing initial association meetings and serves as a
resource for planning meetings and agenda topics.
PEI staff and officers also serve as presenters at associ-
ation meetings. In the past, PEI has provided associa-
tions assistance with executive director searches and
association administration.
     Every year at Convex, PEI's trade show, PEI
holds a petroleum equipment contractor association
luncheon  for officers and staff. Staff training is also
provided annually at the petroleum equipment con-
tractor association workshop. PEI publishes notices of
education seminars and meetings in its TulsaLetter
and provides resources for education and training.
PEI regularly notifies state contractor associations of
regulatory updates.

Beyond the '98 Deadline?
Once the December 1998 deadline has passed, UST
work is likely to slack off and many organizations
have already begun looking to the future. It is proba-
bly safe to say, however, that UST work will continue
at a certain level as long as there  are petroleum stor-
age  tanks. Also, with the  possible emergence of
aboveground storage tank (AST) regulations, a num-
ber of associations have begun providing AST educa-
tion and training programs. There may be more vapor
recovery work down the line, so associations continue
to monitor the regulations and prepare themselves to
provide additional technical training. Whatever the
future brings for the industry, the petroleum equip-
ment contractor associations will be there providing
benefits and services to their members. •
  As PEI Industry Resource Liaison, Bob Young provides
  assistance and resources to petroleum equipment contrac-
  tor associations throughout the U.S., as well as Canada,

long way to sensitize the public to
the  environmental  damage  and
health effects that are caused by
chemical spills
     Some regulatory  folks would
argue that because there are so few
chemical tanks relative to the stag-
gering numbers of petroleum storage
tanks, you've got to choose your bat-
tles (i.e., focus more on petroleum.
tanks than chemical tanks). Yet, each
year, thousands  of people in  the
United States are exposed to haz-
ardous chemicals that are released to
the environment as a result of chemi-
cal-related accidents. Almost all acci-
dents are preventable—a double-
walled tank with interstitial monitor-
ing, a properly labeled  tank, a prop-
erly   attended  delivery,  or  an
emergency vent in the right place at
the right  time could make all the
difference in how we co-exist with
the chemicals in our lives. This is
why New York State regulates chem-
ical tanks.

Chemical Idiosyncrasies
Chemicals have idiosyncrasies that
regulators as well as community
health and safety officials need to
recognize and consider when deal-
ing with the storage, use, and trans-
port of chemicals  in  bulk.  Many
substances are hazardous because of
their specific physical properties. In
an industrial setting, considerations
associated with chemical storage and
operations  center on  the physical
and chemical properties of the mate-
rial used. These properties determine
how the materials behave—how they
react or decompose, mix or remain
separate,  release  or   absorb heat,
change phase, and so forth.
     Flammable liquids, for exam-
ple, will explode or burn only when
 their vapors are mixed with oxygen
in the correct proportions in the
 atmosphere, and then only when
     Firefighters undergo decontamination after entering the area of a recent chlorine leak
                            in New York State.
they are in the presence of a source
of ignition. Other substances are haz-
ardous to human health because of
their chemical, rather than physical
properties. Highly caustic or acidic
substances, for example, can injure
or  destroy  human tissue.  Some
chemicals have the potential to affect
human  health  and cause cancer.
     There are several  parameters
associated  with  the  hazardous
nature of a substance that factor into
how it is stored and handled. Some
of these factors are presented in the
sidebar on page 9.
     UST/LUST  regulators have
become quite familiar with the prop-
erties of petroleum products (e.g.,
gasoline,  fuel  oil,  bunker  oil)—
they're flammable, they possess sim-
ilar volatilities, and they're relatively
insoluble in water. These similar
physical and  chemical properties
make it easier to design appropriate
regulations for the bulk storage of
petroleum products and,  for that
matter,  to deal with  the  cleanup
should a release occur.
     Designing regulations for the
bulk storage of chemicals is more
complicated and presents a greater
challenge. As noted in the parame-
ters listed on page 9, some chemicals
float on water, much like petroleum
derivatives. Others are more dense
than water and sink to the bottom, a
fact which can significantly jack up
the cost  of remediating a chemical
release,  relative to  a petroleum
release. Chemicals that are soluble in
water pose an even greater threat to
drinking water; they require society
to do everything possible to protect
aquifers from contamination. When
we look at relative toxicities, we find
that many chemicals are significantly
more toxic than are petroleum prod-
ucts.

New York Tackles
Chemical Storage
Recognizing the complex nature of
chemical tanks, New York State, nev-
ertheless, bit the chemical bulk stor-
age regulatory bullet. In  1986 the
state  legislature passed the Haz-
ardous Substance Bulk Storage Act,
which required NYSDEC to establish
a program for preventing the release
of chemicals to the environment. On
July 15, 1988 NYSDEC adopted its
Chemical Bulk Storage (CBS) Regula-
tions (Phase I) to implement this law.
     Phase I sets forth a list of over
1,000 hazardous substances  to be
regulated and requires the registra-
tion of AST and UST systems that
store any of these hazardous sub-
stances, either singularly or in com-
bination.  The  regulations  also
require the  appropriate parties to
notify the NYSDEC  of any  haz-
ardous substance spills and to take
prompt remedial action to protect
human health and the environment
in the event of a release.
     Phase II of the CBS program
was adopted on August  11, 1994.
This phase established minimum

requirements and schedules for the
design,  construction,  installation,
operation, maintenance, repair, mon-
itoring, testing, and inspection of
storage facilities.
     The CBS regulations consist of
five parts (Parts 595-599). Part 595
(Reporting Releases) requires own-
ers, operators, contractors, and oth-
ers to report the following types of
releases to the environment:
>  One-time reporting of continuous
   and stable releases;
^-  Reporting of releases  exceeding
   the  reportable quantities  identi-
   fied in Part 597; and
>  Reporting of releases even if the
   release is less than the reportable
   quantity, if the substance released
   could result in a fire or explosion
   or pose a health risk to adjacent
   parties.

This regulation applies to all releases,
including releases  from  chemical
process tanks, certain transportation
accidents, chemical fires, explosions,
and nonregistered facilities.
     Part 596 (Registration) has been
in effect since 1988 and requires the
registration of ASTs with a capacity
of 185 gallons or more and any size
UST. This section addresses registra-
tion fees and prohibits the delivery of
a chemical to an unregistered tank.
     Part 597 (List of Hazardous
Substances)  contains a list of over
   Chemical Factors Used in Designing Bulk Storage
   and Piping Systems, Secondary Containment, and
   Delivery Systems

   • Vapor density ratio - The relative weight of a vapor compared
     with an equal volume of air under the same conditions.
   • Specific gravity - The relative weight of a certain volume of liquid
     or solid compared with an equal volume of water.
   • Water solubility - The proportion of a material that dissolves in
     water, usually at room temperature.
   • Vapor pressure - The pressure of a vapor at the specific tempera-
     ture where the vapor is in equilibrium with its liquid or solid form.
     Vapor pressure is also a measure of a substance's volatility.
   • Boiling point - The temperature at which the vapor pressure of a
     substance is equal to atmospheric pressure.
   • Particle size - The size of the portions into which a substance is
     divided. This property has a bearing on the stability of the substance
     in the environment.
   • Viscosity - The measure of a liquid's resistance to flow due to its
     internal friction.
   • Rate of evaporation - The rate at which a liquid will convert to a
     vapor at a specific temperature and pressure.
   • Melting point - The temperature at which a solid changes to a liq-
     uid at atmospheric pressure.
   • Toxicity - The ability of a substance to produce an adverse effect on
     a biological system.
   m pH - The acidity or alkalinity of an aqueous solution.
   S Corrosivity - The measure of a metal's ability to react with mois-
     ture, usually water.
   • Flash point - The lowest temperature at which a flammable liquid
     or solid will give off enough vapors to support combustion.
   • Ignition temperature - The lowest known temperature at which a
     gas or the vapor from a liquid or solid—in a closed or nearly closed
     container—will self-ignite without the help of a source of ignition.
   • Flammable limits - The lowest and highest proportions of a vapor
     or gas relative to the air that will burn. •
 1,000 hazardous substances and their
 reportable  quantities.  NYSDEC is
 required by state law to regulate all
 substances which are regulated by
 CERCLA, the Federal Insecticide,
 Fungicide,  and Rodenticide  Act
 (FIFRA), and the federal Toxic Sub-
 stances Control Act (TSCA), as well
 as other chemicals known to be haz-
 ardous.
      Part   598  defines   upgrade
 requirements for USTs with a dead-
 line  of  December  22,  1998, and
 upgrade requirements for ASTs with
 a deadline of December 22,1999. Part
 599, which began February 11,1995,
 presents the standards for all new
 and substantially modified facilities.
      In New York, owner/operators of
 chemical or petroleum USTs need to
 know three important items to satisfy the
 requirements for their deadlines:
 >• All USTs must be corrosion resis-
   tant;
 >• All USTs must have a double wall
   or a liner; and
 *• All USTs must be upgraded to sat-
   isfy spill/overfill requirements.

      While owners/operators of
 aboveground storage tanks (ASTs) in
 many other states may not be regu-
 lated, New York  State  regulates
 ASTs to ensure proper management.
 New York requires that AST facilities
 have the following:
 *> A Spill Prevention Report
 >• Secondary containment for ASTs
   and transfer stations
 *• Inspection schedules
 *• Emergency venting
 > Labeling of tanks and piping
 *• Storage of nonstationary tanks in
   dedicated areas.
     Our CBS regulations require
 emergency  venting and  a  rigid
 inspection schedule. Effective August
 11,1996, the regulations also require
 that a Spill Prevention Report (SPR)
 be developed and maintained at the
 storage facility. The SPR must be
 updated  at least once per year and
 immediately after a major release or
major modification. Among other
things, the SPR must contain a copy
of the registration application and
certificate, a site map, an assessment
of releases over the previous 5 years,
a status report on compliance, and a
spill response plan.

LUSTLine Bulletin 26
• Chemical Tanks from page 9

    The SPR is a management plan
that contains useful information for
both preventing and responding to a
spill. The history of leaks and spills
at a facility can provide important
information for preventing future
occurrences. For example, when an
emergency occurs, telephone num-
bers are needed quickly  so that
neighbors and the proper authorities
can be notified. One purpose of the
document is to provide a sound
course of action for employees and
emergency responders.
     Owner/operators are required
to develop evacuation plans and
train all staff periodically so that they
are prepared for such emergencies.
With  a  properly defined SPR in
place, a  facility can expect to mini-
mize/eliminate injury, loss of life,
hospitalization, the extent of subse-
quent remediation,  and liability.
     As of March 31, 1996, New
York State's CBS program had 1,975
registered facilities. These facilities
accounted for 6,644 in-service ASTs
and USTs,  representing a storage
capacity of 58,122,250 gallons for 196
unique  chemicals.  The chemicals
stored in largest volume are sodium
hydroxide, methanol, sulfuric acid,
      Leak Prevention
sodium hypochlorite, hydrochloric
acid, phenol, ammonia, aluminum
sulfate, xylene, and toluene; they
account  for  a combined storage
capacity of 36,538,000 gallons.
     New York State's CBS regula-
tory program is fairly flexible, partic-
ularly with  respect  to  upgrade
requirements for ASTs and USTs.
Tank owners may choose to follow
generally accepted industry consen-
sus standards, or obtain  NYSDEC
approval to follow equivalent prac-
tices. Variances  are also allowed
under the regulations.
     The state is making every effort
to work with industry to find accept-
able   solutions  to  the  required
upgrades and expects these solutions
to be protective of human health and
the environment. NYSDEC is contin-
uing its efforts to remind facility own-
ers of their obligations to satisfy the
regulatory upgrade requirements.
     This June, a compliance initia-
tive got underway. Letters  have been
sent to all registered UST facilities in
the  state, advising them  of  the
December 1998 deadline. Attached to
the  letter is  a copy  of EPA's
brochure, Don't Wait Until  1998. Also
attached is a computerized printout
of the state's information on the facil-
ity's tank and piping systems, based
on  registrations. The facility  is
required to review this information,
which will  be  used to determine
compliance.

                    Georgia Takes An  Innovative Approach
                    to Managing and Financing Compliance
                    and Corrective  Action at State-Owned
                    UST Facilities
                    by J. Robert Wiggins, Jr. and Jill Stuckey
       The State of Georgia is taking
       an innovative approach to
       managing  and  financing
 compliance and corrective action at
 state-owned UST sites. The tank
 management and corrective action
 strategies that  have been  put in
 place are already saving the state
 money, and the financial burden for
 UST capital costs (i.e., tank up-
 grades, replacements, and removals)
 is being spread  over  a  20-year
 period.
     In 1993, staffers in the Gover-
 nor's office began noticing an influx
 of requests from state agencies for
 large sums of money for UST-related
 work.  Because of the  number of
 requests,  the   Governor's  staff
 deemed it prudent to  review the
 state's UST management practices
 and determine how each agency
 intended to manage its tank upgrade
 work. This review process involved
 representatives from all state agen-
 cies and from the UST Management
 Program of the state's Environmen-
 tal Protection Division (EPD).
     The EPD records showed that
 there were almost 1,000 UST sites
 owned by 18 different state agencies.
 Over 85 percent of the sites had not
 yet been upgraded or closed. The
 EPD had been notified about prod-
 uct releases at many of these sites,
 but little site assessment work had
 been undertaken. The agencies had
 been relying on guidance from con-
 sultants, and both the guidance and
 the consultants varied widely from
 agency to agency. As a result, the
 reviewers discovered a glaring lack
 of consistency in new systems stan-

  dards, as weft as a lack of cost-effec-
  tive compliance with. UST regula-
  tions.
       As representatives from EPD's
  UST Program, we (the authors) rec-
  ognized that a coordinated approach
  was essential and proposed to  the
  Governor's  staff that a  separate
  group be established to oversee and
  manage the work at all state-owned
  UST sites. We reasoned that such a
  group could achieve  three crucial
  objectives:
  >• Ranking of all sites by priority/
    need, regardless of agency owner-
    ship;
  > Development of consistent man-
    agement practices,  systems de-
    sign,  and assessment  and/or
    remediation work for all sites; and
  ^ Realization of major cost savings
    by  instituting new methods  of
    supplying fuel to the  state fleet
    and by finding new, more efficient
    ways to assess sites  for potential
    environmental impact.

      Key to this proposal was the
  establishment of a new management
  group which would oversee and
  implement an all-agency UST man-
  agement plan. Funding for all UST-
  related  work   would  now  be
  channeled to this central UST man-
  agement group.
      The proposal was presented to
 the Governor in late 1994. He agreed
 to it and included the plan in his
 FY-96 budget. In early 1995, the plan
 and budget were submitted to the
 General  Assembly.  The  General
 Assembly concurred and assigned
 the new UST Management Group to
 the Georgia Environmental Facilities
 Authority (GEFA), as of July 1995.
 The Assembly also approved the sale
 of  $5 million in bonds (amortized
 over  a 20-year  period)  to fund
 replacement, closure, and remedia-
 tion activities at state-owned UST
 sites. An additional $5.6 million was
 made available in July 1996. Another
 $5  million bond sale will be con-
 ducted in July 1997; more funds will
 be  provided  in  future years, as
 needed.
     The UST Management Group's
 first order of business centered on
 resolving two key questions: What
 was the best way to provide fuel to
 the state's fleet of over 22,000 vehi-
 cles?  and  How  could the  state
achieve environmental compliance at
  its 1,000 sites without spending vast
  sums of money?

  Fueling the Fleet
  Prior to the establishment of the UST
  Management  Group,  each  state
  agency had assumed that most tanks
  would be replaced on a one-for-one
  basis. If so, however, the cost would
  have approached $50 million. A quick
  survey showed us that almost 80 per-
  cent of the state's vehicle fueling sites
  pumped less than 2,000 gallons of fuel
  each month. This stark reality lead us
  to conclude that investment in new
  systems at sites with  such small
  monthly throughput could not be jus-
  tified! So far, we have identified about
  650 fueling locations. By the time our
  program is complete, Georgia's UST
  sites will have been whittled down to
  less than 100.
 !/l quick survey showed us that almost
 |  80percent of the state's vehicle
 ^fueling sitespumped less than2,000
 I gallons of fuel each month. This stark
 f  reality lead us to conclude that
 £ investment in new systems at sites
 1 with such small monthly throughput
         could not he justified!
      But before we could begin clo-
 sure of these tanks, we had to find a
 way to provide fuel to the state's
 22,000 vehicles. Consideration had
 already been given to creating a pri-
 vately administered credit card sys-
 tem for state  fuel purchases but
 without any particular urgency.
 Those of us at the UST Management
 Group realized  that such a system
 was now essential. We discussed the
 situation with the Governor's staff
 and urgently recommended that the
 development of the private credit
 card for fuel purchases be given very
 high priority. (Coincidentally, this
 recommendation came as the Gover-
 nor was working to privatize more
 and more state services and sourcing
 of supplies.) With all parties  in
 agreement, work on the credit card
 system moved into high gear.
     The development of the credit
card system has been supported by
all state agencies. The old gasoline
  purchasing system was cumbersome
  and could not provide timely man-
  agement information. In developing
  the new credit card  system,  we
  decided that it must be set up as a
  true "one-card" system.  Thus,  the
  private vendor who will support the
  system must be able to integrate, via
  a single credit card per vehicle, data
  from retail fuel purchases with data
  from fuel obtained at state-owned
  facilities. Using special computer sys-
  tems and fleet management software,
  the new system will enable a driver
  to use the same credit card to obtain
  fuel from either a private vendor or a
  state facility, thereby creating a single
  tracking and reporting system for all
  fuel transactions. As of this writing,
  vendors are submitting  proposals for
  the system; it is to be operational by
  late 1997, a year before the 1998 UST
  upgrade deadline.
      Meanwhile, we began work to
  bring the remaining sites up to the
  new standards. We established basic
  design elements and developed and
  standardized engineering drawings
  and specifications. The same designs
  are used over and over, with some
 tailoring to site-specific and/or spe-
 cial operating situations. Some pro-
 jects have been completed and more
 are being initiated each month. This
 approach of reducing the tank popu-
 lation,  standardizing designs, and
 converting most facilities to the new
 credit card system has reduced the
 state's capital cost for UST upgrades
 and replacements  from about $50
 million to about $15 million— a 70-
 percent reduction in required funds!

 A Risk-Based Approach to
 Environmental Assessment
 The second part of our program was
 just as crucial as the tank manage-
 ment aspect. We needed to find a
 cost-effective approach for ensuring
 that the state achieved  compliance
 with environmental standards. Our
 traditional approach toward LUST
 site assessment— "zero tolerance"
 and "chasing the plume"—would
 require upwards of $50 million and
 many years to conclude all work.
 Because the state does not tap into
 the State UST Trust Fund to pay for
 cleanups, the required cleanup funds
would have to come from General
Obligation Bonds, which, in turn,

m Georgia from page 11
would be paid back with General
Revenue. Because all  government
units have more demand for funds
than tax revenue, providing these
amounts would come at the expense
of other services and programs.
     In evaluating our site assess-
ment options, we took a look at the
state's  general resource/land use
picture. Over 60 percent of Georgia's
drinking water comes  from surface
sources—streams and/or impound-
ments. Over 40 percent of Georgia's
land surface is  the   Piedmont, a
topography that  consists of tight
soils and water tables greater than 25
feet below surface. The next 50 per-
cent of the state's land surface is
underlain by a surficial  aquifer—
although  shallow-bore   drinking
water wells are quite common in this
area, the state UST sites are typically
long distances from living areas. We
reasoned that inasmuch as over 80
percent of the state's UST sites con-
sisted of small tanks less than 2,000
 gallons in size, each pumping low
 monthly volumes, the  risk of a large
 release at  any one of these sites
 seemed very low. The combination
 of these facts led us to conclude that
 a  majority of  the state facilities
 should pose insignificant contamina-
 tion risk.
      In order to  confirm our intu-
 itive conclusion we had to develop a
 new methodology that would satisfy
 the   environmental   assessment
 requirements, yet cost much  less
 than the old process. Given the limits
 on available funds, we knew that our
 corrective action efforts  should be
 directed at the highest risk sites first.
 Since Georgia's Environmental Pro-
 tection Division has long focused on
 preventing contamination of drink-
 ing water wells, our fkst priority was
 to identify those sites that could
 impact known and active wells.
      We   devised   a   three-step
 approach to satisfy and resolve our
 needs. First, we commissioned a
 physical survey of all UST facilities,
 accumulating site-specific informa-
 tion on such considerations as water
 receptors,  preferential  pathways,
 uses of adjoining property, building
 construction, soil conditions, and the
 location of the USTs on the site. Next,
  we commissioned the development
  of a  risk-based  model that would

 integrate the predictive abilities of
 soils transport models, water trans-
 port models, and gasoline  vapor
 transport models. Last, we had the
 developer of the model input site-
 specific information to create a rela-
 tive  ranking  of risk in order to
 identify which sites to address first.
      The site survey, the first step,-
 was bid on a fixed-cost basis. The
 information we required had to be
 presented both on U.S. Geological
 Survey topographical maps and on
 site-specific drawings. This scheme
 not only provided all of the site data,
 it also created the foundation for the
 next steps. This work was done for
 about $200 per site and  was com-
 pleted in less than 120 days!

 Our Forecasting Tool
 The second step, the development of
 a integrated risk-based model, is the
 key component of Georgia's pro-
 gram. We had  observed that most
 UST sites have some degree of conta-
 mination (from overfilling usually),
 yet probably pose very little risk to
 drinking waters. We also realized
 that, in most cases, whatever conta-
 mination was present in the tank
 excavation would diminish in quan-
 tity as  it moved  through the soil
 and/or to the ground water. Since
 benzene is the most serious health-
 based constituent of petroleum prod-
 ucts, we felt that the development of
 a means to forecast  its potential
 impact on drinking water wells was
 paramount.
      The  contractor  selected  to
 develop the model was charged with
 creating a model that would literally
 integrate predicted  movement of
  contaminants in soil and in water so
  that Georgia could forecast the tim-
  ing and impact of benzene contami-
nation for a given well. The contrac-
tor was asked to evaluate and select
from published, peer-reviewed fate
and transport models and to validate
them with respect to state sites that
had already been extensively investi-
gated. He was asked to regionalize
the sites based on topography and
soils susceptibility. He was asked to
run sufficient trials of the model to
identify which of the many variables
would need to be represented as site-
specific data. Finally, he was asked
to make the new model dynamic to
reflect relative risk as new data are
input.
     This work resulted  in a new
forecasting tool that takes site-spe-
cific data (e.g., direction and distance
to receptors,  probable  depth to
groundwater,   soils   conditions
[including grain-size analysis], soil
contamination tests  results  [ben-
zene], preferential pathways, and
proximity to buildings) to predict the
following:
K If, when, and at what levels ben-
   zene would move through soils to
   groundwater,
*> If, when, and at what levels ben-
   zene would  migrate through
   groundwater to someone's well,
   and
 > Whether gasoline vapors  could
   accumulate in enclosed  spaces
   (basements, sewers).
 Because each  component  of  the
 model feeds data into the other com-
 ponent, any change in one variable
 automatically triggers a recalculation
 for the entire model.

 Ranking the Risks
 The contractor input the data from
 all  1,000 sites to  create a relative
 ranking. The output yielded a raw
 numerical  score  that ranged from
 zero to over 200,000 points. The first
 ranking was based only on the site
 surveys. As such, it  was a valid
 assessment of the potential risk at all
 sites.  Sites with  very low  scores
 could be expected to pose no risk,
 regardless of the amount of product
 released. Sites with high scores could
 pose big problems even if only small
 amounts of product were lost.
       The model is truly dynamic. As
 tanks are removed, and soil contami-

                                       ance. Keep in mind, individual state requirements may differ from federal require-

 A Q & A in the last issue of LUSTLine
 addressed the length of time existing
 USTs can use  the  leak  detection
 method  that  combines  monthly
 inventory with tank tightness testing
 every 5 years. For convenience, we
 will call this leak detection method
 the "combination method."  What
 follows is a clarification of this ques-
 tion based on recent EPA informa-
 tion.
       When can you start using the
 combination method as an approved leak
 detection method?
        The federal regulations state
 that the combination method satis-
 fies federal leak detection require-
 ments only when applied to an UST
 system that meets the performance
 standards for new UST systems or
 upgraded  UST systems. Basically,
 these standards require the UST sys-
 tem to have spill and overfill protec-
 tion and  corrosion  protection for
 tanks and piping.
    . How long can an UST system use
the combination method?
       Federal regulations state that
the combination method can be used
for a maximum of 10 years after the
tank is installed or upgraded with
corrosion protection. Note that this
time period is based on the compli-
ance status of the tank only, not the
entire UST system. (In the last issue
of LUSTLine, we incorrectly stated
that an "extension  is granted"  for
USTs  to  use  the  combination
method; in fact, the period during
which the combination method is
valid is not an "extension" and does
not need to  be "granted" by  an
implementing agency.)
     This information  is basically
consistent with EPA materials circu-
lated to date  and should create no
confusion as long as: 1) the tank and
the rest of the UST  system are
 upgraded at the same time, or 2) the
 tank has corrosion protection added
 after the rest of the system meets
 upgrade standards. In these cases,
 USTs can use the combined method
 for 10 years after the tank has corro-
 sion protection, or December 1998,
 whichever date is later.
     But what about the smaller sub-
 set of existing USTs in which the
 tank has corrosion protection before
 the  rest of  the UST system meets
 upgrade standards? In some of these
 cases, the combined method may not
 be valid for more than a few years.
 As noted above, the federal regula-
 tions require that the entire  system
 be upgraded before the combination
 method can meet the federal leak
 detection requirements. However,
 federal regulations also establish an
 ending date for the period  during
 which this combination method is
 valid. The ending date established is
 10 years after the date the tank has
 corrosion protection (or December
 1998, whichever is later). Since the
 period of validity cannot begin until
 the whole system has met perfor-
 mance  standards  for  new  or
 upgraded USTs, the period of valid-
 ity is less than 10 years only in these
 cases where the tank has been pro-
 tected from corrosion before the rest
 of the UST system meets the upgrade
 standards.

The sample cases which follow illus-
trate three basic possibilities:
 •  Tank and other UST system
   components are all upgraded
   at the same time.
   For  example, a bare steel tank
   installed in 1980 is subsequently,
   in 1997, assessed by means of an
   internal   inspection   and   is
   upgraded with corrosion protec-
   tion, piping upgrades,  and spill
   and overfill protection. This UST
   system can use the combination
   method until 2007,  which is 10
  years following the date of tank
  upgrade.
 • Tank has corrosion protection
   added after the rest of the UST
   system   meets   upgrade
   standards,
   For example, a bare steel tank
   installed in  1980 adds  piping
   upgrades and spill and overfill-
   protection in 1993, but the tank is
   not upgraded with corrosion pro-
   tection until 1997. This UST sys-
   tem  can use the combination
   method until 2007, which is 10
   years following the date the tank
   is upgraded with corrosion pro-
   tection.

 • Tank has corrosion protection
   before the rest of the UST
   system   meets    upgrade
   standards.
   For example, a bare steel tank is
   upgraded with corrosion protec-
   tion in 1988 (or the tank is made of
   noncorrodible  material   and
   installed in 1988),  but the piping,
   spill, and overfill upgrades are not
   added  until  1995. This would
   mean that the UST system could
   start   using  the  combination
   method to meet federal leak detec-
   tion requirements only in 1995
   (when   the  full   system   was
   upgraded) and could use the com-
   bined method only until 1998 (the
   date which is 10 years after the
   tank has corrosion protection). In
   this example, the UST could use
   the combined method to meet fed-
   eral leak detection requirements
   for 3 years (from  1995 to 1998).
   After 1998, the UST in this exam-
   ple would need to begin using a
   monthly  monitoring  method.

     Readers should be aware that
these qualifications  apply also  to
USTs ranging in capacity from 1,001
to 2,000 gallons that use a variant of
this combined method. These small
USTs can use a combination method
of manual tank gauging with tight-
ness testing every 5 years with the
same qualifications as noted above
             • continued on page 14

for USTs using the method that com-
bines inventory control and tightness
testing.
     In all cases, when the combina-
tion method can no longer be used,
monthly monitoring is required by
the federal leak detection regula-
tions. Approved monthly monitor-
ing  methods are  manual tank
gauging (only for tanks 1,000 gallons
or smaller), automatic tank gauging,
statistical inventory reconciliation,
vapor  monitoring,  groundwater
monitoring, interstitial monitoring,
and other methods approved by the
implementing agency  as  equally
effective in detecting leaks
Cx.  Owners/operators of new and
existing USTs are required to perform
release detection for spills and leaks of
regulated   substances   (40   CFR
280.40(a)). For some USTs, one of the
options available for meeting the release
detection requirements combines tank
tightness testing at specified intervals
with  monthly  inventory  control.
Monthly inventory control  requires
owners! operators to perform  certain
activities in order to detect a release of at
least 1.0 percent of flow-through plus
130 gallons on a monthly basis. The
activities required  include recording
measurements of the amount of product
delivered, dispensed, and stored in the
tank each operating day. If a UST is stor-
ing a regulated substance that is added
or removed only a few times a month, or
not at all, is the owner/operator required
to gauge the tank every day the regulated
substance is in the tank, or just the days
during which the regulated substance is
added or removed?
The owner /operator is required to
 conduct inventory control measure-
 ments each day the regulated sub-
 stance is added or removed, and at
 least monthly. The definition of
 each operating day for purposes of
 monthly inventory control requires
 recording tank measurements only
 on those days that a regulated sub-
 stance is added or removed. How-
 ever, the owner/ operator, in order
 to meet the inventory control stan-
 dard on a monthly basis, must also
 record and reconcile delivery, dis-
 pensing, and inventory measure-
 ments at least once a month.   For
 example, if a 4,000 gallon diesel fuel
 UST on a farm has no  deliveries
 and dispenses no fuel for a month,
 then the farm is required only to
 record the amount of fuel in the
 tank (and compare this value with
 the standard) on a monthly basis.
 Note, however, that after 3 months
 of inactivity, closure requirements
 may apply. Also note that inven-
 tory control is, for each tank, part of
 a temporary  release  detection
 option. (See the answer to the ques-
 tion above.) Request EPA's Doing

 ground Storage Tanks (EPA 510-B-93-

      Leak Prevention
 Petroleum  Marketers
 Promote  P2 With Farm
 Customers
 By Liz Nevers
        Partnerships between the public and private sectors can be very effective. A recent
        Farm*A*Syst pollution prevention (P2) initiative targeted gasoline and diesel storage and use on farms. With
        the goal of keeping fuel out of soils, surface water, and groundwater, a group of public-private partners worked
 together to provide farmers with special information packets, to sponsor educational displays at three Wisconsin
 county fairs, and to present several on-farm workshops.
     Funded in part by an EPA
 grant  awarded to  the National
 Farm*A*Syst Program, the partner-
 ship included two Wisconsin petro-
 leum  retailers,  Danco  Prairie FS
 Co-op and Haskins  Gas and Oils;
 project members from the national
 and state Farm*A*Syst programs;
 state petroleum organizations; Uni-
 versity  of  Wisconsin-Extension
 agents and specialists; and a state
 regulatory agency.
     Wisconsin's tank program reg-
 ulates all underground and above-
 ground  storage tanks,  including
 tanks exempted from the federal reg-
 ulations  (these  tanks  have  an
 upgrade deadline of May 1, 2001).
 Getting the word out to this vast reg-
 ulated community was an important
 priority.
     "At the Wisconsin Department
 of Commerce, we like to educate
 before  enforcement," says  LeRoy
 Nordmeyer, aboveground/ under-
 ground storage tank specialist. "This
 [P2] project brought awareness to oil
 jobbers   [marketers]  and  tank
 installers that they need to take a
 leading role in education. It is doing
volumes of work without dragging
people into court—which is not our
goal-
     Dane  County/University  of
Wisconsin-Extension  Natural Re-
source agent, Mindy Habecker, also
believes  education  is  important.
"Underground tanks and fuel tanks
are an issue in Dane  County. I get
phone calls on a regular basis from
farmers who have an underground
tank that they want to remove," she
says. "With the phasing in of a new—
fairly confusing and complex—set of
regulations,  I felt it was a critical

issue. A recent Department of Com-
merce survey found that more than
90 percent of Wisconsin's farm fuel
tanks are not meeting state code."

Farm Petroleum Tank
Information Packet
Since members  of the partnership
team agreed that farmers lack infor-
mation,  a  packet  was devised to:
>•  Create awareness of the pollu-
    tion  and fire  risks  and  their
    impacts
>•  Educate  farmers  about  state
    codes
>•  Give  farmers   directions  and
    tools to prevent pollution
>•  Provide  information  on addi-
    tional  assistance  and services

Rather than creating all new publica-
tions,  each  member  organization
supplied  relevant materials.  The
team decided to make the packet a
working file folder with recordkeep-
ing functions.  The retailers  also
promoted  special  tank-upgrade
equipment, such as automatic shut-
off nozzles, and included coupons in
the information packet to encourage
farmers to purchase the equipment.
     The  retailers' fuel  managers
and the fuel delivery drivers partici-
pated in training sessions to under-
stand the materials and their role in
the project. The drivers, for example,
had the job of delivering the infor-
mation packets during their regular
farm refueling stops and promoting
other activities. Each packet contains:
>•  A fact sheet on the risks petro-
    leum  contamination  poses to
    surface and groundwater
>•  Brochures explaining Wisconsin
    codes for  farm tanks
>-,  Four tank decals, required by
    code
>•  Information  on state funds for
    petroleum cleanup
>  The  Wisconsin  Farm*A*Syst
    Petroleum Storage and Handling
    risk assessment worksheet  and
    fact sheet.
>•  Spill response information
>•  Recordkeeping forms for tanks
>•  Information  on finding  addi-
    tional assistance
     "The  materials were profes-
sionally  done and very  well  put
together," says Dean Hanley, Energy
Department Manager, Danco Prairie
FS Co-op. "Farmers are more sophis-
ticated today, and we got some very
good comments  from the two on-
farm demonstrations."

County Fairs
Along with the local county Exten-
sion office, the retailers also co-spon-
sored an educational display, called
"A Farm Petroleum Tank Check-
Up," at  the Columbia,  Dane, and
Grant county fairs. It provided basic
information on tank hazards, USTs,
ASTs, and management tips. Simple
equipment—like  new  hoses and
automatic shut-off nozzles—was
also shown.
     The Extension offices also pro-
vided technical and outreach sup-
port—developing        publicity
materials, mailing out  flyers and
news releases, giving local radio and
television reports, networking with
local officials and  organizations, and
helping provide  free space at the
county  fairs (space  at  the Dane
County Fair would have otherwise
cost $650).
     "In Dane County, it is difficult
to reach people  unless you use a
multi-pronged    approach,"   says
Habecker. "You never know if a per-
son will open up  a packet and read
all of the information; they may pre-
fer to actually see and talk to some-
one—to get the information 'from
the horse's mouth'."

On-Farm Demos
The county agents suggested hold-
ing on-farm workshops—"Farm Fuel
Tank Demonstrations"—to provide a
nonthreatening setting  to discuss
regulations  and liability issues, as
well as to show actual farm tanks.
The displays from the county fairs
 were also used on the farms, and the
 Extension agents again took the lead
 in planning and  running the demon-
 strations.
      "Having the display gives  the
 project a longer life, since  it can be
 shipped around the state and used in
multiple counties," Habecker said.
 "You can also get more breadth in
 getting the information out there,
 without targeting the competitors of
 the cooperative that you're working
 with."

 Benefits of Partnerships
 Once a partnership dynamic gets
 started, it can easily have a ripple
 effect, drawing  in more and more
 interest and participation. For exam-
 ple, because of their many and varied
 contacts, the local Extension agents
 and petroleum marketers brought in
 new partners for local activities (e.g.,
 emergency response staff, local fire
 chiefs, insurance underwriters, and
 state tank specialists). The on-farm
 demonstrations  also attracted real
 estate agents, county health officials,
 environmental consultants, insurance
 agents, local press, farm press and
 other petroleum retailers, as well as
 farmers.
      "I'm not sure this project can be
 seen on our bottom line, but it has an
 intangible return—a positive effect on
 our image," Dean Hanley says. "We
 got a lot of good publicity out of  it."
     One insurance underwriter was
 so excited about the project that he
 began distributing the information to
 his territorial underwriters as well as
 all of his farm policy holders. •

                        Enforcement
                    Field  Citations
                    New Hampshire's  First  Choice For
                    Compliance  Enforcement
                    by Lynn A. Woodard
      On July  1,  1994,  the  New
      Hampshire Department of
      Environmental     Services
(DBS) adopted Administrative Rule
Part Env-C 603 Field Citation Pro-
gram for Underground Storage Facil-
ities. In retrospect, the adoption of
this rule was  a milestone in the
state's underground storage tank
(UST) program. It was one of only a
few distinct actions in the program's
history that can be looked back on as
a defining point. The administrative
fine-field citation has  become the
first choice as an enforcement mech-
anism for the UST  program...and
with good reason. The success rate
for payment of the fine and compli-
ance with the regulations for the pro-
gram's   first   2   years   was
approximately 75 percent. (See graph
on page 17.)
     Why did we develop the field
citation program? I suspect New
Hampshire's available enforcement
mechanisms and procedures do not
substantially differ  from those of
other states. Typically, if enforce-
ment is initiated against an UST facil-
ity,  it  is   in  the  form of  an
administrative order, administrative
fine, consent agreement, proposed
permit  revocation, or civil  action
involving the state's Attorney Gen-
eral's Office. All  of these actions
require paperwork  and levels of
review that cause delays in issuance.
Furthermore, the  fines are severe
enough that, if ever issued, they
encourage appeals. As a result, valu-
able time is wasted, and compliance
is delayed or not obtained.
     Prior  to   1994,  when  DBS
adopted the field citation rule, only a
few enforcement actions had been
initiated. Fewer than five enforce-
ment actions were  pursued each
year. There were two overriding rea-
sons for this inactivity: (1) the pro-
gram was in its development stage,
and staff time was dedicated to other
aspects of the program; and (2) the
benefits derived, versus the  cost
expended (in staff time and other
resources),  could  not justify  the
action.
    We, in the program recognized
that if we were to get serious about
enforcement, we would need an
enforcement mechanism that would
be easy to issue and easy to track.
Paperwork and review would have
to be kept to a minimum. Ideally,
such a mechanism would be issued
on-site, where, following a compli-
ance audit, the inspector would dis-
cuss any violations with the facility
owner. To be effective, the fine had
to be large enough to convey the
message that DBS was serious about
obtaining  compliance, and small
enough to ward off an appeal in the
majority of cases. The action also had
to send a clear message that DBS was
only interested  in  protecting the
waters of the state and would prefer
that the owners and operators spend
their resources attaining compliance,
not paying expensive fines.
    With such a mechanism, DES's
goal of gaining compliance with the
technical aspects of tike UST rule as a
means  of preventing releases  or
detecting them  early-on could be
achieved. The field citation met all of
these criteria and more.

Developing The Program
When the idea of developing a state
UST field citation program was first
proposed, we thought that a statu-
tory modification would be required.
The prospect of having to convince a
legislative subcommittee that an
additional punitive measure  was
necessary was not a pleasant one.
Fortunately, however, our Enforce-
ment  Coordinator,  an  attorney,
determined that statutory authority
(RSA146-C) already existed to estab-
lish administrative fines and that the
field citation was just an alternate
form of the standard administrative
fine.
     To make our field citation pro-
gram viable, we had to develop a
schedule of fines that was particular
to the field  citation and separate
from the standard administrative
fine. We structured the citations such
that fines would range from $25.00 to
$100.00 per violation. The schedule
contained a listing of 21 separate vio-
lations; each UST system in a facility
could constitute a separate violation.
     For example, if an UST facility
had three tank systems, and each of
them failed to have the necessary
paperwork for inventory monitoring
or tank gauging, DBS would assess a
fine of $100 per tank system or $300.
To take this further, the violation
could be applied  per day  or per
month, whichever was applicable.
As you can see, a simple field cita-
tion  can begin to  add up  to real
money. To  make  certain that the
effective enforcement criteria were
followed, we made the following
parameters part of the rule:
> A  fine shall not be proposed for
  more than $100 per violation;
>• The total proposed fine shall not
  exceed $1,000; and
^- If the total proposed fine exceeds
  $500, the amount in excess of $500
  shall be suspended.
If the respondent corrects the viola-
tions and pays the $500 fine within
30 days of the date of the notice, pay-
ment of the  suspended portion is
waived.

Implementing the Program
The rule was adopted with no objec-
tion from anyone. Our next step was
to obtain authority for UST field
inspectors to issue the citations on-
site.  Heretofore, the authority to

tiadfeeentbie purview of the commis-
sioner and/or the division director.
In the case of field citations, delega-
tion of authority was transferred to
the UST Compliance Section and its
staff via an internal memorandum.
The field citation program became a
high profile pilot project; if it proved
to be an effective enforcement tool, it
would be cloned for other programs
within the DBS.
     To ensure that citations were
not issued for unsubstantiated viola-
tions, which would result in unneces-
sary appeals,  and to avoid having
proposed  fines  overturned  upon
appeal, staff were  instructed that
facility owners would be afforded at
least one chance to come into compli-
ance before a field citation was issued.
     As  it was,  on-site  visits  to
explain regulatory requirements and
to demonstrate how best to attain
compliance, mailings of deficiency
letters, mass  mailings containing
specific requirements and deadlines,
and follow-up post cards were nor-
mal procedure. Now, to further
ensure the success of the program,
initial inspections were targeted to
areas where a release was most likely
to have the greatest impact (i.e., well-
head protection areas)  and to those
systems that  were most  likely to
have a release (i.e., unprotected bare
steel tanks greater than 25 years old).
(In New Hampshire,  unprotected
bare steel tanks greater than 25 years
old must  be permanently closed.)
     To simplify the process even
further, during the early stages of the
program,  our staff members were
limited to issuing citations for two
types of violations: Those associated
with leak detection, and those for
unprotected bare steel tanks greater
than 25 years old.
     Next, DBS had to develop the
actual citation form,  print it, and dis-
tribute it to the staff. We decided to
use a standard 8.5- x 11-inch page so
that we could list all 21 violations
with  their respective fines.  This
design method  was easy for  the
inspector and the facility owner to
read, so it made for more accuracy in
citing the violation. Each page has
space for the name of inspector, the
name of facility, the date, and the
facility owner's signature.
     We numbered the  citations and
assigned a block of these to each
inspector. The back of the form con-
tains the appeals procedure and
space  for the  facility owner  to
explain the corrective action steps he
or she will take and the anticipated
date for attaining compliance. This
form has been very successful,  no
appeals have cited the form as the
source of any misinformation.

Measuring Results
Compliance is the key to release pre-
vention. When we look at program
results, we need to keep in mind the
program goal: To encourage compli-
ance with the technical criteria of the
rale and thereby prevent  or detect
releases. To accurately measure the
results of the Field Citation program,
we made it our business to track the
facilities that received field citations
and their compliance status.
     To accomplish this, we devel-
oped a Lotus spreadsheet that con-
tained all pertinent information. The
spreadsheet was divided into three
sections—proposed fine data, negoti-
ations/hearings data, and compli-
ance data. The compliance items
were coded and shaded-in when
compliance on a particular violation
was attained, allowing for a compli-
ance status assessment at  a  glance.
                                    Authority to use the field cita-
                               tion was available  in July 1994.
                               Development of the citation form and
                               other administrative needs, however,
                               delayed issuance of the first citation
                               until late January 1995. Since then, 90
                               field citations have been issued—20
                               in 1995, 32 in 1996, and 38 as of the
                               end of May 1997. (See the "Field Cita-
                               tion Program Results" graph.)
                                    Compliance rates for 1995 (18
                               out of 20) and for 1996 (21 out of 32)
                               are 90 percent and 65 percent respec-
                               tively.  However,  these numbers,
                               alone, do not show how really suc-
                               cessful the program has been. For
                               example, many of the facilities repre-
                               sented as remaining out of compli-
                               ance have,  in  fact,  established  a
                               schedule with DBS for coming into
                               compliance. A secondary benefit, but
                               one that is  just as important but
                               impossible to measure, is the number
                               of facilities that voluntarily attained
                               compliance because of this field cita-
                               tion initiative.
                                    One benefit of the program that
                               can be measured is leverage. When a
                               field citation is issued to an owner
                               with multiple facilities, DBS lever-
                               ages its assets by requiring that the
                               owner  reconcile the  compliance

records for all his/her facilities with

Thus, if deficiencies are noted, the
owner is required to establish a
schedule for returning all facilities to
compliance. By issuing 90 field cita-
tions, we have addressed compliance
at 220 UST facilities.

Effective In More Ways
Than One
The field citation has proven to be a
highly effective compliance enforce-
ment mechanism. It  has had the
effect of streamlining the state's UST
compliance enforcement program.
Prior to its adoption, the issuance of
90 standard proposed administrative
fines, associated hearings, and subse-
quent determinations during  an
equal period of time for one program
would have  been  unheard of. It
would have severely overburdened
the system and transmitted the mes-
sage that the enforcement program
was ineffective.
     The adoption and implementa-
tion of the Field Citation program
has been an effective mechanism in
gaining compliance in communities
with  wellhead protection areas to
protect valuable  drinking  water
resources. It has been a major factor
in encouraging facility owners to
permanently close unprotected sin-
gle-walled steel tanks greater than 25
years  old,  thereby  preventing
releases from occurring.
     By preventing releases we have
reduced the potential number of new
leaking underground storage tank
sites. This, in turn, has reduced the
number of claims on the state reim-
bursement fund and has  saved the
fund hundreds of thousands of dol-
lars. The saved dollars are available
to fund the investigation and clean
up of other sites.
     Finally, lest we forget, Decem-
ber 22, 1998 looms on the horizon.
Because this enforcement mechanism
is already in place and  has been
tested, it will be called upon as the ini-
tial enforcement mechanism to be
used for those facilities that do not
meet the 1998 compliance deadline. •

  Investigation and Remediation:
MTBE - Beware the
False  Positive
by Blayne Hartman

 I \ /hat is the official EPA method for mea-
 w V suringMTBE in soil and water samples? Actu-
ally, there is no official method. And herein lies the
potential problem with reported MTBE results.
     Increased  concern over  the
presence of MTBE in the environ-
ment by the regulatory community
has created a demand for MTBE
analyses  from soil and water sam-
ples collected  from  LUST sites.
Because  no official  EPA  method
exists, laboratories have modified a
variety of EPA methods to analyze
for MTBE. The most commonly used
methods are  EPA 8020, 8240, and
8260. While  results  provided by
these methods may be fine, both reg-
ulators and consultants need to be
aware that there are critical differ-
ences among these methods which, if
not understood, could lead to the
incorrect interpretation of reported
MTBE values.
     EPA Method 8020 is a gas chro-
matography (GC) method that uses a
photoionization detector (PID). The
method is  designed to detect aro-
matic hydrocarbons, the most com-
monly targeted compounds of which
are benzene, toluene, ethylbenzene,
and xylenes (BTEX). MTBE can also
be detected by this method. MTBE
elutes, or passes through the detec-
tor, earlier in the analytical run than
the BTEX compounds, which means
that it takes no additional time to
analyze a sample for MTBE. As  a
consequence, some laboratories have
included MTBE in their 8020 analyti-
cal runs for little to no extra charge.
But as the saying goes: "Beware the
free lunch."
     Because of pricing pressures,
many analytical laboratories have
compressed the  "run time" for 8020
from 20 minutes to less than 10 min-
utes. This reduced run time increases
the potential for compounds to co-
elute (i.e., pass through the detector
together) and be misidentified. This
problem can be especially significant
for MTBE because several alkane
compounds elute close to MTBE and
are present in gasoline in large quan-
tities. The result is false positives —
over reported  MTBE values that
result from the co-elution of the alka-
nes. This problem is greatest for soil
vapor and soil samples, but it can be
significant for groundwater samples
as well.
     EPA methods 8240 and 8260
are gas chromatography methods
that use a mass selective detector
(GC-MS). These detectors differ from
other typical GC detectors because
they have the ability to identify com-
pounds based on their masses. This
means that MTBE can be recognized
and quantified individually, even if
other compounds are co-eluting with
it. Thus, MTBE values from these
methods tend to  be more reliable and
false positives should not occur. This
analysis, however, is more expensive
than an 8020 analysis.
     The solution? Use a combina-
tion of these methods to ensure valid
results  and minimize  costs. Nonde-
tect MTBE values reported by method
8020 should be  fine.  MTBE values
from samples with low gasoline val-
ues (<5000 ug/1  and 100 mg/kg) are
more likely to be reliable because low
values of the co-eluting alkanes are
also  likely. As  gasoline values in-
crease, so does the potential for over-
reported MTBE values. Depending on
site-specific goals, it is advisable to
confirm a subset of the MTBE results
reported by method 8020 by one of

  dent and Technical Director of TEG,

 Now Available
 EPA's  New Guide on Expedited Assessment Tools
 For UST Sites
     EPA has developed a guide to
     help  UST regulators evaluate
     and  promote  expedited site
assessments at UST sites. Expedited Site
Assessment Tools For Underground Stor-
age Tank Sites: A Guide For Regulators
(510-B-97-001) is designed to enable
the reader  to answer the following
basic questions about site assessments
atUSTfadliti.es:
>• What is  an expedited site assess-
  ment?
^- How is an expedited site assess-
  ment conducted?
^- What equipment can be used in an
  expedited site assessment?
>• Under what site  conditions are
  specific  site  assessment  tools
  appropriate?

     EPA's Office of Underground
Storage Tanks (OUST) estimates that
at least 360,000 sites are likely to
require site assessments in the next
few years. The majority of these
assessments will result from owners'
and operators' closing or replacing
old tanks to comply with the '98
deadline. Additional  assessments
will be required to investigate back-
logged sites and new releases.
    There   have   been  many
improvements  in site assessment
technologies over the last few years.
When they are systematically inte-
grated into  the site assessment
process, these new technologies can
speed up the on-site decision-mak-
ing process.
    As the first step in the correc-
tive action process, site assessments
are critical to making appropriate
remediation  decisions.  Expedited
site assessments can streamline the
corrective action process, improve
data collection, and reduce the over-
all cost of remediation.
    The new EPA guide is orga-
nized into six chapters: Introduction,
The  Expedited Site  Assessment
Process, Surface Geophysical Meth-
ods, Soil Gas Surveys, Direct Push
Technologies, and Field Methods for
the Analysis of Petroleum Hydrocar-
bons. It is designed for federal, state,
and local regulators who review cor-
rective action plans and site  assess-
ment reports. It will also be useful to
consultants, engineers, lenders, pub-
lic health professionals, and others
involved in the cleanup or remedia-
tion of LUST sites.

                   Connecticut DEP Developing; Multimedia
                   Expedited Site Assessment Guidelines
                   For LUST Sites
      Under contract to the LUST
      Trust Fund Program of the
      Connecticut Department of
Environmental Protection (DEP),
and with additional support from
the Connecticut Department of Pub-
lic Works, Professor Gary A. Rob-
bins at the Department of Geology
& Geophysics of the University of
Connecticut is developing multime-
dia guidance on conducting expe-
dited site assessments at UST sites.
The guidance is being developed to
help  the regulated  community,
environmental consultants, and
DEP contractors achieve improved
UST site remediation approaches.
     To date, two reports in hard
 copy and on-line have been issued.
 These are:

 >• Recommended  Guidelines   For
   Applying Field Screening Methods
   in Conducting Expedited Site Inves-
   tigations at Underground Storage
   Tank Sites in Connecticut (Novem-
   ber 30,1996) and

 > Recommended Guidelines For Mul-
   tilevel Sampling of Soil and Ground-
   water in Conducting Expedited Site
   Investigations  at  Underground
   Storage Tank Sites in Connecticut
   (March 12,1997).
 A third  report  entitled,  Recom-
 mended Guidelines For Evaluating
 Three-Dimensional and Hydrogeologic
 Data Obtained in  Conducting Expe-
 dited Site Investigations at Under-
 ground  Storage  Tank  Sites  in
 Connecticut is due out next year on
 CD-ROM.
     These guidance reports stress
 the need to delineate the  three-
 dimensional distribution of gasoline
 and diesel fuel contamination above
 and  below the water table.  The
 reports provide recommendations
 on sampling, determining pertinent

hydrogeologic properties, estimating
contaminant mass and attenuation
rates, and presenting data. In this
regard, the guidance reports comple-
ment and supplement EPA's recently
completed document on expedited
site assessment for regulators (see
preceding article), but provide more
detail in terms of field application.
The reports emphasize the applica-
tion of direct push methods for sam-
pling and the use of field screening
techniques for delineating contami-
nation.
     The  guidance  presented in
these reports is based on long-term
research conducted at the University
of Connecticut and project-specific
efforts  that   entailed  literature
reviews on field analytical methods
and multilevel sampling, a survey of
manufacturers of field  screening
methods and equipment for conduct-
ing multilevel sampling, laboratory
tests of field analytical methods, and
field tests of select analytical and
sampling methods  at UST sites in
Connecticut.
     Field testing included compar-
isons of different methods for con-
ducting  multilevel  groundwater
sampling and soil sampling below
the water table for entrapped prod-
uct using direct push methods. This
year's efforts include comparisons of
data obtained from conventional
and   expedited  site assessment
approaches.  Also, evaluations are
being performed to assess the effec-
tiveness of remediation approaches
at several UST sites that were based
on three-dimensional data collected
in conducting expedited site assess-
ments.

EPA  Concerned About
Schaefer/Allard LUST Trust
Fund Legislation
      On April 23, the House of Rep-
      resentatives  passed   the
      Schaefer bill, HR.  688, the
"Leaking  Underground  Storage
Tank Trust Fund Amendments Act
of 1997."  Senator  Allard  (R-Col-
orado) introduced an almost identi-
cal bill, S. 555, on April  10. This
legislation expands the use of the
federal LUST Trust Fund, allowing
the fund to be used to supplement
state UST assurance/cleanup funds
to reimburse responsible parties for
the costs of cleanup and to pay state
fund administrative expenses and to
enforce UST release prevention tech-
nical standards. The legislation also
mandates that EPA distribute at least
85 percent of the LUST Trust annual
appropriations to  the states and
explicitly prohibits the use of the
fund for upgrade, replacement, or
closure of old tanks.

    about the implications of this
 ^.i^^^^^tt^A.-JAi-'-aSfcia;'^^^!^./!
 :i ^legislation; primarily from the
  ^standpoint that the legislation
 ^y&sentjaily takes an eating pot of
 money and spreads it over a broader
      range of allowable uses.
     The LUST Trust Fund program
was originally authorized under the
1986 Superfund Amendments and
Reauthorization Act and was reau-
thorized for 5 years in December
1990. It was funded by a 0.1 cent per
gallon tax on motor fuel. Although
authority to collect the tax expired in
December 1995, Congress can con-
tinue to appropriate funds. Approxi-
mately $1.0 billion remains in the
fund. The President is requesting
reinstatement of the tax in FY-98.
     At present the fund may be
used for site cleanups, where the
owner/operator   is   unwilling,
unknown, or insolvent; for oversight
of responsible party (RP) cleanups
and enforcement; and for general
support and management.
    Since the Schaefer bill was first
introduced, EPA has voiced con-
cerns about the implications of this
legislation;  primarily   from  the
standpoint that the legislation essen-
tially takes an existing pot of money
(i.e.,  EPA's annual appropriation
from Congress) and spreads it over a
broader range  of allowable uses.
With this fact in mind, the Agency
has three major concerns.
    First, at current appropriations
levels, EPA is concerned that by sup-
plementing state financial assurance
funds with money from the LUST
Trust  Fund, resources needed  to
oversee RP cleanups and remediate
abandoned sites could be diverted,
thereby   reducing  protection  of
human health and the environment.
    EPA's second concern also has
to do with  supplementing state
cleanup funds in that federal dollars
would be used to reimburse RPs
who are known, willing, and able to
pay for  cleanups. The LUST Trust
Fund was not designed to provide
funding for cleanups on behalf of
solvent, viable responsible parties.
    Finally, H.R. 688 and S. 555
would codify EPA's grant award
patterns, specifically requiring that
at least  85 percent of Trust Fund
appropriations be distributed to the
states. While historically, EPA has
awarded states approximately  85
percent  of its annual Trust Fund
appropriation, the agency believes
that it should maintain the flexibility
to revise the percentage distribution
and allocation formula for distribut-
ing monies to the states. The Agency
feels that such flexibility allows it to
respond more appropriately as envi-
ronmental risks and resource levels
change and to fulfill its responsibil-
ity in  Indian  Country,  which
includes emergency response and
corrective action.
    EPA does support the enforce-
ment uses of the LUST Trust Fund
provided in the new legislation. •

  Investigation and Remediation
              CAFI Anyone?
              Selecting  the Right Cleanup
              Technology  for  a  Site
              by Richard Spiese and Chuck Schwer
   In the "good old days"  in Ver-
   mont, the state site manager went
   to most LUST sites and, with the
assistance of the responsible party's
(RP's) consultant, performed a pre-
liminary on-site evaluation of the
severity of the LUST contamination
and the risk it posed to sensitive
receptors. Based on this evaluation,
the site manager and the consultant
determined what type of remedia-
tion method, if any, was needed to
contain and remediate the contami-
nation. This decision was often based
more on past experience than on site-
specific data. In many cases, these
decisions were made within days or
weeks of discovering the release, and
usually without the benefit of on-site
pilot tests to evaluate the effective-
ness of the chosen technology.
     By the early 1990s, however,
this  modus operandi began  to
change, primarily in response to a
proliferation of LUST sites. No
longer could program personnel visit
every site. Instead, they spent an
increasing  portion  of their time
reviewing  consultant reports  and
evaluating the  effectiveness of site
cleanups. In doing this, they soon
learned that many  of the remedial
decisions made in the past were less
than perfect. Assumptions that had
been made in the field were often not
completely accurate, and remedial
systems sometimes needed modifica-
tions to reflect the different site con-
ditions.
     In 1994, in response to this find-
ing,  the Vermont  LUST program
adopted the Corrective Action Feasi-
bility  Investigation,  or   CAFI,
approach to selecting cleanup strate-
gies. Under this new approach,
before  a  cleanup  technology is
selected, a formal CAFI must be per-
formed. The CAFI must  contain
specified elements that are deemed
necessary for determining the appro-
priate corrective action technology
for a given site.
     The RP's consultant must eval-
uate one or more technologies that
are appropriate to the unique condi-
tions of the site, perform an on-site
pilot test, evaluate risk, and justify
the selection of the  recommended
technology. The CAFI allows for the
review of natural attenuation as a
corrective action technology. It also
calls for a review of the costs of dif-
ferent technologies and a cost-benefit
analysis of the different remedial
options. Depending on site-specific
conditions (e.g., geology, receptors),
a CAFI may be straightforward (e.g.,
a report on the results of a pilot test)
or more complex (e.g., a formal
review of multiple applicable tech-
nologies).

Refreshingly Cost-Effective
In preparation for the Sixth Annual
State Fund Administrators  Confer-
ence this June, Vermont LUST pro-
gram staff  evaluated the average
costs of cleanup at CAFI sites versus
non-CAFI sites. This evaluation pro-
vided us with three exciting pieces of
information about sites where formal
CAFIs had been completed:
>  The  remedial  costs  were often
   reduced;   .
>  The  duration of the remediation
   was often shortened; and
>•  Expensive remediation costs were
   avoided at  sites where remedia-
   tion was found to be technically
   infeasible.
     The average cost of remediat-
ing sites where formal  CAFIs were
completed was significantly less than
that  of remediating sites where no
formal  CAFIs  were  prepared.
Although   most  site  managers
expected this to be the case, all were
surprised by the magnitude of this
savings.
     A review of the costs of prepar-
ing a CAFI showed that the average
cost for performing and reporting a
CAFI was $8,500.00;  the range was
from $1,300.00 to $32,350.00. These
differences in costs were  based
mostly on the complexity of the site
and whether one or multiple remedi-
ation technologies were evaluated.
    The average cost of cleanup for
sites without a formal CAFI was
$261,930 (based on  the review of
remediation  costs  at  30  sites),
whereas the average cost of cleanup
for sites with a formal CAFI was
$174,049 (based on  the review of
remediation costs at 15 sites). These
data represent a per  site savings of
almost $100,000.00! Not bad for an
investment of only $8,500.
    At seven sites where a  CAFI
had  been  completed,  the   CAFI
indicated that site conditions were
such that any corrective actions other
than natural attenuation were techni-
cally infeasible. In these  instances,
the average cost of  the, initial site
investigation,  preparation of the
CAFI, and long-term monitoring was
$60,000.00.
    Although most of the cleanups
initiated without a CAFI  were suc-
cessful, many of  the approaches
needed to be modified, expanded, or
changed after they  were imple-
mented. These modifications ulti-
mately increased  the cost of the
cleanup.
    In Vermont,  we have  found
that it is a good investment in time
and money to thoroughly evaluate
all potential site cleanup technolo-
gies before deciding on a final reme-
diation technology. Vermont's LUST
cleanup program now requires the
preparation of a formal CAFI at all
sites, except  in emergency situa-
tions...and a nice hot cup of Java to
reward all involved. •

 LUST in  the  Brownfields

      Brozvnfields, brownfields, brownfields...everybody's talking about brownfieldsl
      brozvnfields are abandoned, idled, or under-used industrial or commercial site.
 casualties resulting front decades of industrial activity—where expansion or redevel
 cated by real or perceived environmental contamination. Brownfields pose risks to p\
 create zones of environmental blight in many communities.
While brownflelds are found in sub-
urban and rural areas, the problem is
most prevalent in urban areas where
many properties that would other-
wise be prime for development lie
dormant because they are tainted by
hazardous wastes, as well as by leaks
and spills from underground and
aboveground storage systems.
     Private parties are reluctant to
invest in these properties because of
liability concerns and cleanup cost
uncertainties. Financing is difficult to
obtain because lenders fear that envi-
ronmental and legal obstacles will
make it difficult for borrowers to
repay  their loans.  These circum-
stances prompt developers to shift
their attention to dean sites in rural
or suburban communities while the
brownfields—prime   urban   and
industrial sites  that are already
served by transportation infrastruc-
ture and utilities—remain  aban-
doned or unproductive.
     Throughout the country, the
cleanup  and  redevelopment  of
brownfields is being seen as a key to
the  revitalization of urban  areas.
Putting these properties into produc-
tive use can create jobs and increase
local tax revenues. It can also help
slow "urban sprawl" and the prob-
lems that go with it, including
increased air pollution and loss of
open space.
     EPA and many states see the
need for a coordinated response to
the brownfield situation and have
begun  developing  programs  to
specifically address problems com-
mon to  brownfield sites. EPA's
Brownfields Redevelopment Initia-
tive, for example, was established
with the mission  of  preventing
brownfields from coming  about in
the first place and cleaning up exist-
ing brownfields in an effective and
timely manner.
     Across the  country, there are
approximately 450,000 real or per-
ceived brownfield sites. In an effort
to remove obstacles in the  way of
performing brownfield assessments
and cleanups, EPA is trying to ease
the  stringent   liability  scheme
imposed by the  Comprehensive
Environmental Response, Compen-
sation, and Liability Act (CERCLA).
These efforts include creating com-
fort, or  closure, letters that certify
that a site is clean, clarifying lender
liability provisions, and exploring
the use  of state voluntary cleanup
programs at low priority, non-
National Priority List sites.
   "State program managers should
  \eep abreast of what is happening in
   their states, especially if certain
I provisions of proposed legislation
\    may have a negative impact
w- -•-'-•     on their program."
                ., Sammy Ng, EPA Office of
               " Underground Storage Tanks
Where LUSTs Are Concerned
While brownfields are usually asso-
ciated with Superfund or hazardous
waste sites, many of these sites are
actually  former commercial and
industrial sites that contained old or
abandoned USTs. In fact, in some
areas, UST sites may account for half
of the  brownfields  sites. Unfortu-
nately, because  of  this link with
Superfund sites, most of the federal,
and an increasing number of state,
activities have focused on the diffi-
culties in  addressing  these sites
under  current Superfund policies
and procedures.
     "These activities, such as state
voluntary cleanup programs and lia-
bility schemes, while addressing the
problems usually associated with the
Superfund program, can also affect
a state's UST/LUST program," says
Sammy Ng  of  EPA's Office  of
Underground Storage Tanks, "espe-
cially with regard to the cleanup and
redevelopment of UST sites. State
voluntary cleanup programs will
likely set forth a whole new way of
doing cleanups.
     "These voluntary cleanup pro-
grams are  generally designed  to
streamline  Superfund  cleanups,"
explains Ng.  "If state  LUST  pro-
grams are included under these pro-
grams,  it could  create additional
hurdles for LUST program cleanups.
As  a very  simplified example, a
state's Superfund cleanup program
could be streamlined from 50-steps
to 10-steps. Yet,  that state's LUST
program may use a 5-step process.
There is the  potential, then, that
LUST sites that fall under the state's
brownfields program could be sub-
ject to the more complicated 10-step
process."
     Also, in an effort to secure the
timely turnaround  of  brownfield
sites, state LUST program managers
may be asked to sign off on sites
through the issuance of closure let-
ters. This could create extra work for
already taxed LUST programs by
creating an additional set of priori-
ties.
     "We suggest that  state LUST
program managers  be vigilant,"
says Ng. "State program managers
should keep abreast of what is hap-
pening in their states, especially if
certain provisions of proposed leg-
islation may have a negative impact
on  their program. Some  recently
passed  brownfield  legislation  in
Maryland and Michigan did affect
USTs. Depending on how they are
defined from  state to state, brown-
fields can be  a plus or  a minus  in
meeting state  LUST  program
goals." H

 Tanks Subcommittee
 The Tanks Subcommittee has been
 very active over the last 6 months
 on a variety of issues of concern to
 state UST programs. The Subcom-
 mittee met in April at the Mid-
 year ASTSWMO meeting in New
 Orleans. All four task forces were
 represented at  this meeting, and
 good progress was  made on a
 variety of issues, including the
 UST "Report Card," which is cur-
 rently undergoing revisions. For

 UST Task Force
 The UST Task Force has been busy
 on a number of important UST
 issues. Many of these issues are
 driven by the 1998 deadline for
 upgrading of  USTs. The  Task
 Force continues to work on the
 "Report  Card on the Federal
 UST/LUST  program."  As this
 project now includes all the Task
 Forces in the Tanks Subcommit-
 tee, the TIE Task Force has taken
 the lead  as project coordinator.
      The UST Task Force has also
 provided comments for the devel-
 opment of an EPA - OUST/ASTM
 standard for  certifying UST com-
 pliance with the 1998 technical
 standards. This proposed ALICE
 (Acceptable Liability and Compli-

 • Is Leak Detection Working? from page 3	

point where all UST systems are perpetually tight. The
sheer number of active UST facilities, combined with the
human propensity to make mistakes, guarantees that
leaks will be with us for a long time. The question is, will
we find them sooner? Or later?

To Err Is Human
As a footnote, it is dear to me that lack of owner/opera-
tor understanding of leak detection is a key factor con-
tributing to the ineffectiveness of leak detection methods.
Few owner/operators understand inventory control well
enough to believe what it is telling them. Few on-site per-
sonnel really understand ATGs.
     Even secondary containment is beyond the ken of
many. On some recent facility inspections, I encountered
sincere, well-meaning operators of secondarily contained
tanks who were using manual monitoring to meet their
leak detection responsibilities. Unfortunately, one was
sticking his float vent valve thinking it was his interstitial
space, the other was sticking his primary tank for the
presence of water, thinking this was leak detection. We
have a long way to go in the realm of educating the UST
owner/operator population. •

                   nation and grain-size analysis tests are run, new infor-
                   mation is input into the model. Using this model, Geor-
                   gia staffers are able to run site-specific evaluations. By
                   comparing known conditions at a site with higher risk
                   scenarios, these same staffers can quickly assess if this
                   site really needs further assessment, or  if it can be
                   closed with "no further action."
                       We expect this approach will eliminate the inva-
                   sive and costly site investigations that normally follow
                   the discovery of contamination at a facility. We are
                   really operating on the "80-20 rule," which suggests
                   that 80 percent of the sites are low risk, while the other
                   20 percent might have significant problems. With this
                   method, we are able to focus limited funds on the high
                   risk sites, while quickly resolving the rest. In taking this
                   approach, we expect to decrease the cost of assessment
                   and remediation efforts from $50 million to less than
                   $20 million.
                       So, here's the bottom line: From an early cost esti-
                   mate of about $100 million to deal with tank replace-
                   ments and cleanups for some 1,000 sites,  we are now
                   down to a cost of about $35 million. This is a 65 percent
                   reduction, quite a figure for anyone. •

Enforcement Initiative
During May 1997, the states and
EPA undertook a joint effort to
focus attention on their commit-
ment to enforce the UST regula-
tions. Together, states and EPA
inspected about 9,000 UST facili-
ties.  Violations  of  the release
detection requirements were iden-
tified at more than 2,500 of  the
facilities inspected. States and EPA
issued 1,700 Notices of Violation,
750 warning letters, and 400 field
citations.  Formal  enforcement
actions were recommended or ini-
tiated in several cases. States and
EPA proposed or collected fines
totaling more than $900,000; large
fines proposed in three cases in
Region 2 accounted for more than
half of the total.

• Tank Time.
Developed by  the  Tennessee
Department  of Environmental
Conservation's Division of Under-
ground Storage Tanks, in collabo-
ration with EPA OUST, this new
video used a fictional TV show,
"Tank Time," to present an amus-
ing discussion of the federal 1998
requirements for corrosion protec-
tion, spill and overfill prevention,
and compliance options available
to UST owners and operators. Ten-
nessee staff wrote the script to" be
generally applicable to UST own-
ers and  operators nationwide;
however, the video does note that
state requirements may differ and
urges viewers  to check with their
state authorities.
     Tennessee sent a copy of the
video, along with a state-prepared
booklet, to every registered tank
owner or operator in the state.
EPA sent a copy of the video to
every state UST program manager
and EPA regional UST program
manager. Tank Time is available

•  1997 Flexible Piping
Survey
Because flexible piping systems
differ significantly from the more
traditional steel  and fiberglass
piping systems, EPA OUST has
periodically commissioned a sur-
vey of flexible piping manufac-
turers. This new survey updates a
similar  flexible  piping  survey
published in 1995. The 1997 sur-
vey  includes information  on
which companies are making flex
pipe, product name, construction,
compatibility, diameter available,
date of first installation, number
of installations, installer training
required and/or provided, mini-
mum bend radius, test pressure,
listings, and materials warranty.
Copies can be downloaded from
OUST's Home Page (see above.)

which is a revised, updated edi-
tion of LTST Program Facts, con-
tains   a   new   section   on
"brownfields." The booklet was
designed mainly  for state and
EPA staff, but other interested
parties will find it  useful.  It
should help regulators handle

ings/presentations, respond to
legislators'  questions,  write
speeches, and  provide informa-
tion to other  agencies  and the
public.
