           WASTE OIL
          COMBUSTION
           By Bob Blaszczak
             CTC/OAQPS
      The CTC, in cooperation with the
   State of Vermont Department of Envi-
   ronmental Conservation (DEC),  has
   completed "Waste Oil  Analysis  and
   Waste Oil Furnace Emissions Study,"
   EPA-456/R-95-001. This study charac-
   terizes waste oil (i.e., used crankcase
   oil), the air quality impacts of combust-
   ing waste oil  in air atomizing  space
   heaters, and the need to adjust Vermont
   DEC rules governing used oil combus-
   tion.
      This study resulted from a request
   made by the Vermont DEC to the CTC
   to assist in a study  of  waste  oil re-
   quested by the Vermont General As-
   sembly. The DEC planned the project,
    collected and analyzed waste oil
    samples, selected facilities to be
    tested, determined the
    air quality
    impact  of
    emissions
    from waste
    oil combus-
    tion, consid-
    ered the need to
    change  DEC regulations
    based on  study results,
    and  provided  overall
    project  management.
    The CTC  provided on-
    site testing of waste
    oil  combustion units
    through  the Source
    Characterization
    Group A in the Emis-
    sions, Monitoring and Analysis Division,
    OAQPS/EPA.
       Waste  oil samples were collected
    from 21  gasoline and diesel mainte-
            nance facilities and do-
            it-yourself drop off sites.
            Analysis of  used  oil
            samples    revealed
            higher levels of several
            contaminants over No. 2
            home heating oil. Waste
            oil test results are pre-
            sented in Table 1. Note
            that some of the con-
taminants found are the result of perfor-
mance additives  in the virgin oil and are
not necessarily the result of contamina-

         AIRWA VES
            By Chuck Darvin
          CTC Co-chair, AEERL
      Greetings from the Co-chair! If you
   are wondering whether the CTC has
   had a change in management since Bob
   Blaszczak usually writes this column,
   be assured,  he just had an attack of
   writer's cramp this quarter.
      However, for those of you who are
   not familiar with its structure, the CTC is
   divided into two sections, gathering ex-
   pertise from two Environmental Protec-
   tion Agency  (EPA) sponsor organiza-
   tions. Bob is  the Co-chair from the Of-
   fice of Air Quality Planning and Stan-
   dards (OAQPS), responding to your
   calls  regarding regulatory questions
   and  related technology  application  is-
    sues. On the other hand, I Co-chair the
    CTC on behalf of the Air Pollution Pre-
    vention and Control Division (APPCD)
    of the  EPA Office of Research and
    Development (R&D).  The  APPCD
    group, consisting of research engineers
    and  scientists,  responds to  calls for
    technical information  and R&D assis-
    tance.
       The research side of the CTC can
    call on the immediate services of four
    engineers and  scientists to  address
    your technical issues. In addition, we
    frequently call  for technical support
    from the 75 engineers and scientists of
    the sponsoring  research laboratory to
    conduct studies in a broad range of
    technical disciplines, especially issues
    involving air emissions.
       The R&D side of the CTC has, in my
    opinion, the most exciting assignments
of the two groups. Since most of the
technical studies result from your re-
quests, they tend to be more practical,
with immediate application to yourtech-
nical problems.
      Some examples of successful
studies include research in the area of
tire burning, and emissions from roofing
and road asphalt. At your request, the
CTC conducted research into the na-
ture of  emissions from  tire burning,
thereby becoming a widely recognized
and used authority on the composition
and characteristics of the emissions.
The documents from our studies on
roofing and road asphalt emissions are
regarded as widely  recognized  and
used information on pollutants from
these sources.
   As a result of your HOTLINE calls,
the CTC developed SIMS (Surface Im-
                (continued page 3)

tion from use in engines.  The majority
of samples complied with the constitu-
ent and property limits stated in  Ver-
mont regulations.
    Stack testing was conducted on
five atomizing waste oil furnaces cur-
rently in service and one No.  2 fuel oil
furnace.   A sample of the fuel  com-
busted at each site during the emission
test was also collected and analyzed.
Stack emission test results indicated
higher levels of contaminants over that
of No. 2 fuel oil. Waste oil combustion
emission test results are presented in
Table 2. These results were modeled to
determine compliance with Vermont's
ambient air quality  standards for the
pollutants listed.

   'Arsenic concentrations are not reported due to analytical difficulties with accurately determining arsenic concentrations at the necessary
   levels.  While the laboratory can quantify arsenic concentrations in oil greater than 250 ppb, under the procedures of method 3050 some
   organic arsenic compounds are lost through volatilization, resulting in poor spike recoveries and the possibility of false negative results.
   Only one sample had an arsenic concentration >250 ppb and that concentration was reported as >2 ppm.

                     OIL SUPPRESSION OF PM AT GRAIN  ELEVATORS
                                    SBAP PROJECT UPDATE
    SBAP sponsored testing of a grain
elevator in Greenwood, Nebraska was
completed  in August 1994; however,
the efficiency of oil suppression technol-
ogy was less than expected. Since oil
was applied in the leg of the elevator,
this result could have been caused by
inadequate  mixing  of oil and grain.
Greater efficiencies are anticipated if oil
is  sprayed  during active
grain tumbling. As a result,
the National  Grain and
Feed Association, with the
cooperation  of EPA's
Emissions, Monitoring and
Analysis Division, SBAP
and CTC, will be conduct-
  By Bob Blaszczak, CTC/OAQPS

ing additional tests this summer.  The
new tests should document the effec-
tiveness of oil suppression technology
under more optimal conditions.
   At the Greenwood site with the oil
suppression system operating at the
typical 25 psi, the test results indicated
about 60% efficiency for both PM 10 and
total suspended particulate(TSP) when
              ^Handv Dry Cleaners
transferring  milo,  and  69% and 48%
efficiency for PM10 and TSP, respec-
tively, when  handling corn. With the oil
suppression system at20 psi, efficiency
remained about the same when han-
dling corn, but dropped considerably
when handling milo.
   The  SBAP and CTC will keep you
advised.   Just check the CTC NEWS
               and CTC or SBAP
               BBSs for updates on
               the test results. We
               hope to have a report
               based on all valid test
               results by early  fall
               1995.

    TECHNOLOGY  NOTEBOOK

HAP-PRO 2.0, YOU HAVE
     TO INPUT VALUES

         By Lyndon S. Cox
   Senior Environmental Employee

    A few weeks ago, I got a call on the
HOTLINE from a person who had a
software problem. The caller had down-
loaded HAP-PRO version 2.0 from the
CTC Bulletin Board System (BBS), and
found that for thermal incineration and
catalytic incineration the electrical con-
sumption, and  therefore the cost of
electricity,  was  being computed  as
zero.  How could this be?
    First, I contacted the Project Officer
and outlined the problem that was en-
countered.  I noted that electrical power
consumption is calculated in the Control
Cost Manual (EPA 450/3-90-006) from
which HAP-PRO is derived.
    The Project Officer went to the pro-
grammer who encoded the  computer
program for HAP-PRO.  The program-
mer proceeded to look into the program
and found that the calculation was  in-
deed  present in  HAP-PRO.  Then the
programmer traced the parameters to
ensure  that they were being entered
and computed properly by HAP-PRO.
The programmer found that, to com-
pute the electrical power consumption,
the pressure drop has to have a non-
zero value.  The pressure drop is found
among  the parameters of the  control
device.   This value  must be entered
because there  is  no explicit  default
value.
    Why isthis the case? In the Control
Cost Manual, the electrical power con-
sumption is given by the equation:
              1.17x 10-4 Q
 Power fan=
Where:  Powerfan is in kilowatts.
    Qtotal is the actual flow volume cor-
rected for temperature.
   • P is the pressure drop in inches of
water, and has no explicit default value
in HAP-PRO. Therefore, the computa-
tion assumes a de-
fault value of zero.
    • is the fan and
motor efficiency,
which has a default
value  of 60%  in
HAP-PRO.
    The    power
consumption   is
multiplied  by the
hours of operation
per  year and the
cost per kilowatt-
hour to give the an-
nual cost of electricity. That means that
a non-zero value for pressure drop must
be entered to obtain a non-zero value for
the electrical consumption and the cost
of electricity.
    Without actual values, this pressure
drop can be estimated. Page 3-55 of the
Control Cost Manual gives reasonable
values for pressure drop in incinerators
and heat exchangers as indicated in the
table above.
    These values are additive. That is,
athermal incinerator with a 50% energy
recovery by heat exchanger would have
a pressure drop of 4 inches of water in
the incinerator itself plus a pressure
drop of 8 inches of water in the heat
exchanger. The overall pressure drop
would be 12 inches of water.  However,
the total pressure  drop is  required,
which also includes the pressure drop in
the duct work bringing flow to the incin-
erator and taking flowfrom the incinera-
tor to the atmosphere.  One example
problem  in the Control Cost Manual
uses a total pressure drop of 23  inches
of water.
    The basis for pressure drop in duct
work is discussed in Chapter 10 of the
Control Cost Manual, which is the Third
Supplement  to the  Control Cost
Manual. This pressure drop consists of
losses through straight  ducts,  fittings,
branch devices, venae contractae, and
stacks. The pressure drop across duct
work for  the particular  incinerator can
vary widely, and must be determined for
each installation.  Therefore, we can
refer you to either Chapter  10  of the
Control  Cost Manual or a good  Me-
chanical Engineering Handbook to cal-

culate the pressure drop for the duct
work in your installation.
    Be aware that, when using HAP-
PRO, you must enter a value for the
total pressure drop across the incinera-
tor and its duct work to obtain an accu-
rate power consumption. The cost of
electricity, and therefore the annual op-
erating cost, depend on this value. But
please remember, the value computed
is only as good as the input data.
    Fortunately,  the  calculator is
present in HAP-PRO version 2.0 to help
you do any necessary calculations.

     RBLC EMPHASIZES
          POLLUTION
         PREVENTION

    Recent EPA policy and rules re-
garding  air pollutant  emissions have
increasingly emphasized "pollution pre-
vention" (P2) as the preferred alterna-
tive or, at least, a complement to add-on
control equipment. P2 refers to process
changes, changes in  raw materials or
fuels, and other methods designed to
prevent or reduce  pollution  at  the
source. The RACT/BACT/LAER Clear-
inghouse (RBLC) has  just completed a
projectto bring it up-to-date with respect
to P2 and to enhance the productivity of
data base queries related to P2 informa-
tion.
    First, to  highlight P2  information
within the data base, several data fields
at the pollutant level have changed. A
logical field was added to indicate what
each permit requires  for  a specified
pollutant:

    *  No P2 or add-on controls
    *  Add-on control equipment
       (hardware)
    *  Pollution prevention methods
    *  Both add-on controls and P2
       methods.

    Also, asingle, longercharacterfield
was added to hold narrative information
about required P2 methods and add-on
controls. This single data field replaces
separate control equipment and pro-
cess modification data fields. The new
field allows room for more detailed de-
scriptions  of  prevention and control
methods and  should  make the RBLC
data base more helpful to users. Both
new logical and character fields  are
searchable. Pollutant data screen and
the download reports have been revised
to accommodate new data fields.
    The second part of our effort was to
review all determinations in the current
database, paying particular attention to
information about P2.  Information in
data base fields labeled "Control Equip-
ment" and "Process Modification" was
transferred to the new logical and char-
acterfieldsdescribed above. Wherever
possible, standardized terms were used
to insure that text searches can suc-
cessfully find all the applicable informa-
tion. For example, the phrase "FUEL
SPEC", for fuel  specification, now ap-
pears in all determinations which re-
quire specific fuels (low sulfur coal or
fuel oil, for example).   We also  evalu-
ated the completeness and technical
consistency of  information about P2
methods.  For those determinations in
which existing information was  either
completely missing or  of  questionable
applicability to the specific process, we
contacted the submitting state or local
agency to  obtain correct and complete
information and added it to the data
base.
    Hopefully these changes will give
users easieraccessto P2 information in
the RBLC data base.  Submitting agen-
cies should also find that the longerdata
field makes it easier to describe P2 and
control methods required atthe facilities
they permit.
   EXPANDED HELP FOR
             RBLC

    If you're a long-time user of the
RBLC, you may consider yourself an
expert who  doesn't need  any help.
However,  you  might want  to look at
these recent upgrades to our on-line
help.  We've added a pick list of  SIC
codes in both Query and Edit.  Also,
we've revised the Edit help to indicate
which fields are required before a deter-
mination can be promoted from the tran-
sient data base.  We're only trying to
help!
    NEW ADDITIONS TO
 REGULATION DATA BASE

    The RBLC  regulation data base
(REGS) now lets you scan all rules in
the data base — without  doing a
search. A new "Browse" option, avail-
able from the REGS main menu,  lets
you view the complete list of regula-
tions.   The list is sorted by affected
facility name so that you can readily find
rules of interest to you.   In addition to
viewing the rules on-line, you can mark
selected rules and download them to
your local PC. Choose a regulation from
the list, goto the regulation data screen,
and mark the rule fordownloading.  Re-
peat this process for as many rules as
you like, and then choose a  download
format. Use Browse if you only want to
view rules on-line or if  you are  just
interested in  a particular affected facil-
ity. It's quickerthan building a query and
searching the data base. When  you
need to access rules for certain process
types  or pollutants,  Query is still  the
most efficientway to locate information.
    REGS contains summaries of  fed-
eral regulations enacted in response to
the Clean Air Act and Amendments
(CAAA). For newer rules, the complete
text of the regulation is available on the
CAAA BBS. To help you find this infor-
mation, the regulation data base  now
includes the names and  locations of
files on the CAAA BBS.  Rules available
on the TTN are flagged with a "C" in the
affected facility list, and the CAAA BBS
file information is available in a pop-up
box on the process list screen.

        CTC EXPERT
      KELLY LEOVIC
        By Heather Sigmon,
       Acurex Environmental
    If you call the CTC HOTLINE with a
question about Indoor Air Quality, you
may find yourself in a discussion with
Kelly Leovic.  Pleasant and easy to talk
to, Kelly will give you all the information
you need and more about her area of
expertise at EPA/APPCD's Indoor Air
Branch.  Her current projects include
identifying  and characterizing sources
of indoor  air emissions from  office
equipment such as copiers and printers,
developing pollution  prevention tech-
niques  and guidelines for formulating
less toxic aerosol consumer products,
and publishing a biannual newsletterfor
the Air  Pollution  Prevention & Control
Division entitled "Inside  IAQ."
    A native  of Buffalo,  NY,  Kelly ar-
rived in Durham in 1980 to attend Duke
University  without having ever seen
Durham or Duke.  Fortunately for the
EPA and the  numerous  community af-
fairs Kelly participates in, she fell in love
with the Triangle area and has been
here since, with the exception of a year
spent working in Colorado. After earn-
ing a Bachelor  of Science in Geology
and Math in 1983, Kelly continued on at
Duke, earning a Masters of Science in
Civil and Environmental Engineering in
1985.   Additionally,  in 1992, Kelly re-
ceived an MBA  from the Fuqua School
of Business at  Duke University, a de-
gree which she feels has made her a
more well rounded person.  Rest as-
sured though, Kelly has no future plans
to leave the EPA and climb the corpo-
rate ladder!
    Kelly began working for APPCD in
1987, doing mainly field work for the
Radon  Mitigation Branch. Kelly's dili-
gence  and  hard work  earned her a
bronze  medal for scientific leadership in
reducing significantly elevated levels of
radon in two schools in Nashville,  Ten-
nessee.  This  and other radon work
ultimately led to the publication of "Ra-
don Prevention  in the Design and Con-
struction of Schools and Other Large
Buildings," a technical guide for archi-
tects and engineers, as well as an infor-
      BUS BBS CHANGES NAME TO RBLC BBS!
 No, it's not the new math. The familiar name of the BACT/LAER Informa-
 tion System (BLIS) is changing! We'll now be known as the RACT/BACT/
 LAER Clearinghouse (RBLC). The name change is long overdue since the
 Clean Air Act Amendments of 1990 added RACT to our name in November
 1990.  We had resisted the change fearing that no-one would recognize
 us.  But, they say change is good, so I
 suppose this could be a good thing! Just
 be sure to  look for us under our  new
 name,  the RBLC.
 (Remember,  the
 TIN technical area
 list is in alphabeti-
 cal order, so  our
 name will be fur-
 ther down. Really!
 It's still us!  Check
 it out and see!)

administrators to learn the importance
of radon  prevention.   In 1992 Kelly
moved over to the Indoor Air Branch
where she began her work with office
equipment and aerosol emissions.
    Kelly  has participated  in  several
EPA-sponsored educational outreach
programs.  Through the EPA Scientist
Teacher Partnership, Kelly would go to
an  area elementary school once  a
month to teach the classes of a teacher
shewasassignedto. Shehasalsobeen
part of a one-day science fair program
for local high school students.
    In addition to all her other work for
the Indoor Air Branch, Kelly is organiz-
ing a symposium on Engineering Solu-
tions to Indoor Air Quality Problems to
be held in late July. She was also on the
planning committee of the EPA in  Re-
search Triangle Park, for the celebra-
tion of the 25th Anniversary of Earth
Day. One  may wonder how, with so
much to do, Kelly has time to answer
CTC calls,  but she is never too busy to
help someone needing information.
Kelly sees answering CTC calls as  a
great way of passing on information and
another way she can help educate  oth-
ers on issues regarding  indoor air.
    Kelly,  her husband Todd, and  new
baby Cody love to travel and are hoping
to take a trip to the Virgin Islands some-
time this summer.  It sounds like a great
way to relax.
