   TECHNOLOGIES FOR
 LOW CONCENTRATION
  ORGANIC VAPOR GAS
         STREAMS
        By Bob Blaszczak
          CTC/OAQPS
   The CTC has completed "Survey of
Control Technologies for Low Concen-
tration Organic Vapor Gas Streams,"
EPA-456/R-95-003.  The term organic
vapor (OV), as used in this report, in-
cludes both volatile organic compounds
(VOC) and organic hazardous air pollut-
ants (HAP). The purpose of this study
was to identify permitted control devices
that have been installed and  demon-
strated to be effective  for treating low
concentration OV gas streams, particu-
larly those with high  air flow rates. For
    this report,  low concentration means
    100 ppm or below and high flow rates
    means those above 100,000 cfm.
    Manufactures were contacted to iden-
    tify locations where low concentration
    OV control  systems have been in-
    stalled and tested. Then, State and
    local agencies were contacted to
    obtain permit and source test infor-
    mation. The types of technologies
    considered in this report are listed
    in TABLE 1.
       Technologies
    are  commercially
    available to treat low
    OV gas streams,
    some with efficien-
    cies >99%.  As can
    be expected,  the
    lower the concentra-
    tion   in  the  gas
    stream the higher
    the control cost. Ad-
sorption-based technologies are the
most popular control systems for treat-
       ing low OV gas streams based
        on the number of commercial
        installations. The paring of
         adsorption  and desorption
         steps (e.g. rotary carbon
           and zeolite beds) that
            concentrate  OV for a
              separate treatment
                                                                                 (continued page 2)

    Well it's 1:45 Sunday afternoon, July 9,1995. It's a sunny
day in the mid to upper 80's. A great day to be at the lake or
beach (or down the shore for you folks back home in PA &
NJ). But here I sit at my home computer trying to put together
the last few items for the July CTC NEWS.  I hope  your
summer has been more relaxing than mine and that this
edition of the CTC NEWS reaches you before Labor Day.
    It has been very busy here. We've been trying to put the
final touches on a few overdue CTC reports, finalize the CTC
annual report for  FY94 (Yea, I know it's almost FY96, but
what else is new?), establish the new U.S.- Mexico Border Air
Pollution Information Center,  put out the annual RACT/
BACT/LAER Clearinghouse (RBLC) update report, and get
the Small Business Assistance Program (SBAP) electronic
                    bulletin board system (BBS) operational while maintaining all
                    our regular CTC services - all of this with less resources than
                    in years past. (Although staff resources look about the same
                    on paper, most CTC staffers have acquired new non-CTC
                    duties.) I feel like we are really testing that line about doing
                    more with less.  Remember that story about all the work that
                    has to  get done.  It finds an excuse for everyone else in the
                    world except the storyteller (in this case, me) and the person
                    he's telling it to. The punch line is that there's no one left but
                    the other person and me to do all the work, so let's get to it.
                    Well, I  think they laid off the other person!
                       I am glad to announce that we have completed several
                    CTC reports that address existing and emerging technologies
                    for treating low concentration organic vapor emissions (lead
                    article), prevention  and control options for ammonia emis-
                    sions, and State and local regulations that have gone beyond
                    VOC CTG RACT requirements. There are articles on each
                    report in this edition of the CTC NEWS. If you're interested
                    in the  CTC FY94 Annual report, it should be available in
                    August, just in time for our annual meeting with our STAPPA/
                    ALAPCO advisory group (it's in final editing).

step (usually an  incinerator) are in-
creasingly proposed, especially for high
flow OV streams.
    Absorption/stripping and ultraviolet
(UV)/ozone catalytic oxidation also are
successfully being used to treat low OV
streams and, based on limited cost in-
formation, may be competitive with the
more widely used adsorption based pro-
cesses in certain  cases.  In addition,
regenerative incineration units are be-
ing proposed by venders to treat low OV
gas streams.
    There is a trend for venders to col-
laborate to provide "best-of-breed"
combinations of devices to make up a
case specific control system. The de-
velopment of these hybrid systems is
developing  at a rapid  pace  which  ap-
pears to be driven by the implementa-
tion of new and existing regulations.
    Currently, 25  control systems for
low concentration,  high flow OV gas
streams are know to exist in the U.S. All
are either permitted, being permitted, or
installed under a consent order. Docu-
mentation in the form of permits and
source test results    Incineration
was requested for
all these devices
during this study.
Descriptions  and
relevant details on
all these systems,
such as process
diagram, inlet con-
centration, flow
rate, industrial ap-
plication, and  lo-
cation,  are pro-
vided in the report.
   Control of low
concentration OV
streams is cur-
rently one  of the
most   dynamic
segments of the
air pollution control technology industry.
The technologies as well as their appli-
cations  are undergoing rapid change
and development.  This study offers a
snapshot of low OV  technology at a
particular point in time.  Anyone using
this report should be prepared to seek
out updates on these technologies, es-
pecially on  cost-effectiveness data.
The  CTC will  consider updating  this
report periodically to adequately reflect

    We actually did get the U.S.-Mexico
Border Information Center on Air Pollu-
tion, CICA  (Centro  de Informacion
sobre Contaminacion del Aire in Span-
ish) on line on May  1, 1995. It offers a
bilingual (Spanish & English) HOTLINE
(919/541-1800),  and  many CTC  type
services to support efforts to improve air
quality along the border.   CICA's pri-
mary target customers are the Federal,
State and local government  air pollution
agencies and universities in  Mexico and
the U.S. who are working on  air pollution
problems along the border. Mr. Jaime
Mendieta,  a  senior  environmental em-
ployee, has joined the CTC and will be
answering the CICA HOTLINE.  If
you're working on U.S.-Mexico border
issues and need help, give Jaime a call.
    The annual RBLC report is moving
along and should be to the printer by the
end of July.  Agency RBLC contacts
should be receiving their copies in Sep-
tember.  Remember, all the information
in this years  report is available now!
Just turn on your PC, get on-line with the
OAQPS Technology Transfer Network
(TTN) and select the RBLC BBS.  All
current and historical data in the Clear-
inghouse will  be at your fingertips.  By
the way, if you didn't notice, our name is
changing from BUS (BACT/LAER In-
formation System) to RBLC. We don't
mean to confuse you, but we think its
time to  switch  to the name actually
established for the Clearinghouse in the
1990 Clean Air Act Amendments. De-
pending when you read this, the change
                 may or may not have happened yet. So,
                 if you don't see one of these names look
                 for the other on the TTN menu.
                     Joe Steigerwald  has suggested
                 that we change to a quarterly or sea-
                 sonal designation for the CTC NEWS
                 rather than the January, April, July, and
                 October designations that we have his-
                 torically used.    He  almost  has me
                 convinced to make the change, but I'm
                 concerned  that a less specific target
                 date to get out the NEWS may result in
                 a more lax attitude about getting the job
                 done.  I feel bad enough if I get the
                 NEWS to you a month or two late. I can't
                 imagine how I would feel if you got the
                 Winter edition in the Spring or Fall.
                     I hope you're  having a great sum-
                 mer. See you in October (at least we'll
                 try)!

       BEYOND PACT
     Mohamed Serageldin, Ph.D.
	ESD/OAQPS	

    The "Beyond VOC RACT CTG Re-
quirements" study is completed. This
study was requested by the Lake Michi-
gan  Air   Directors  Consortium
(LMADCO) and should help states  in
their emission reduction efforts to attain
the national  ambient air quality stan-
dards (NAAQS) for ozone.  The study
identifies State, local, and District regu-
lations that  exceed reasonably avail-
able control technology  (RACT) re-
quirements  that are specified  in the
Federal control techniques  guidelines
(CTGs).  States can use this informa-
tion to tighten  requirements  for CTG
RACT source categories.
    CTG  groups I, II, and III are the
focus of this study. A maximum of six
state  regulations were considered for
each  source category.   Regulations
from eight states (Colorado, Connecti-
cut, Maine, New Jersey,  New York,
Rhode Island, Texas, and Utah)  and
two California control districts were ex-
amined.  The two California Districts
evaluated were the Bay Area Air Quality
Management District (AQMD) and the
South Coast AQMD.  The more strin-
gent regulations and those that we iden-
tified to have pollution prevention provi-
sions were summarized for quick refer-
ence in a tabular format (see Table  1 for
an example).
    The original request from LADCO
was to evaluate the stringency of the
different regulations since more strin-
gent regulations would  be  aimed to
achieve higher reduction in emissions.
We recognize, however, that  a more
stringent requirement in a regulation will
not always directly translate into a re-
duction  in emissions.  For  example,
more stringent emission limits on the
VOC content of coatings (including
inks) do not necessarily result in reduc-
tions in emissions, unless the total
amount of the lower VOC coatings is
also restricted by the regulation in terms
of a production parameter (a material
balance approach).  Nevertheless,
                 (continued page 4)
                                             CTC News page  3

-------
BEYOND PACT
(continued from page 3)

tighter emission limits were marked in
Table 1 as more stringent.
In most cases comparing strin-
gency of emission limits was straightfor-
ward. However, many of the regula-
tions had additional (sometimes more
specific) requirements than those re-
quired by PACT in the CTG. Many of
those proved difficult to evaluate for
stringency; for example the emission
impacts of requirements specifying
general design criteria, equipment
specifications, or work practices are
difficult to determine. If an additional
requirement in a regulation did not ap-
pear to result in a quantifiable extra
reduction in pollution, the regulation
was not termed more stringent than the
CTG RACT.
In this study a distinction is made
between two aspects of a regulation
that affect the emission reduction
achievable: the stringency of the regula-
tion and the applicability of the regula-
tion. In Table 1 an "X" under the column
labelled "Stringency" identifies those
regulations found to be more stringent
than the CTG. The X under the column
labelled "Applicabili V' is used to identify
those regulations that provide specific
exemptions or affect different source

c State/District rule affects additional sources and may provide additional reductions relative to CTG

The term applicability was used to high-
light the possibility that the regulation
may result in lower (or higher) reduc-
tions. An X under pollution prevention
meant that the requirement in the regu-
lation would lead
to quantifiable reduc-
tions at the source of pollution. The

NEW RBLC FEATURES SAVE, JUMP, AND MARK
By Jo Ann Kerrick, VfGYAN
nates this duplicate work. You can save
The RACT/BACT/LAER Clearing-
house (RBLC) has made several im-
provements to help you work more effi-
ciently. These new features will get you
to your data faster. They're available
now! Try them out.

Save Search Criteria
The Query module in the RBLC
information system allows you to
search any of its data bases using cus-
tomized combinations of search fields,
operators, and values. This capability
gives you tremendous flexibility, but it
can be extremely frustrating when you
have to re-enter the same criteria in
order to search a different data base.
The RBLC now has an option that elimi-
your search criteria and automatically
reapply it to another data base.
When-
ever you're exiting from the query menu
after building a search criteria, the sys-

It shows the

the search is successful, you can imme-
diately view or download the data. Just
as with other searches you perform, you
can use the advanced search option to
"Jump" to Facility
The Browse module of the
regula-
tion data base (REGS) was designed to
let you scan all of the rules in the data
base without doing
a potentially time-
consuming search. Two new options let
you move around the complete
rule list
and mark information for download in
record time. Browse sorts the
regula-
tion list by affected facility name to help
you find rules of interest as you page
through the data base. A new

option allows you to enter a letter and
move directly to the  affected facility
whose name begins with that  letter.  If
you are looking for the  rule for "SULFU-
RIC  ACID PLANTS",  the jump option
saves you the trouble of paging through
the rules from A to R.  If the data base
does not contain any  rules that begin
with  a  particular letter, jump moves
down the rule list to the affected facility
that begins with the next higher letter in
the alphabet (for example, "RUBBER
TlRE MFG" when you try to jump to "Q").
Jump may not help you locate a rule
exactly in all cases, but it is a good way
to move quickly around the entire REGS
data base.

"Mark" for Download
   In addition to viewing rules on-line,
Browse  allows you to mark  selected
rules and download them to your local
PC. The original version required you to
choose a regulation from the list and go
to the regulation data screen in order to
mark the rule for downloading.  A new
"Mark" option at the rule list is faster to
get to and lets you mark several rules
with fewer keystrokes.  When you se-
lect mark, a pop-up box prompts you to
enter the appropriate mark option (Fig-
ure 1).  You can mark or unmark all of
the rules currently displayed  on the
screen,  or you can mark/unmark a
single rule. For single rules, this option
acts as a toggle, switching the mark on
or off. If you're only interested in one
rule,  it doesn't  much matter how you
mark your selection. When you want to
download a group of  rules, the mark
option is noticeably faster.  You can
mark the rules of interest to you while
paging through the rule list.
   Try these new options in  REGS
Browse, and see for yourself how quick
and easy it is to locate information you
need.                         E9

   AMMONIA CONTROL
     AND P2 OPTIONS
         By Bob Blaszczak,
           CTC/OAQPS
    The CTC has completed "Control
and Pollution Prevention Options for
Ammonia  Emissions," EPA-456/R95-
002.  This report was undertaken to
provide CTC HOTLINE callers who
have expressed concern over the haz-
ards of ammonia with needed pollution
prevention (P2) and control technology
information.  Although Congress de-
cided not to include ammonia in the list
of hazardous air pollutants  in Section
112(b) of the Clean Air Act, ammonia's
toxicity, explosive nature and odor prob-
lems make it a concern that needs to be
considered by environmental and
health agencies.
    The main  sources of  ammonia
emissions are fertilizer production, coke
manufacturing using the by-product re-
covery  method,  fossil  fuel combustion
through  the control of NOx, livestock
management, and refrigeration.  This
CTC report focuses on these industries
since they  are the only ones that have
been identified as implementing P2 or
control  methods to reduce ammonia
emissions.  The technologies used by
these industries include wet scrubbers,
condensate strippers, recovery and re-
cycle techniques, reducing agent limita-
tion, capture systems, and good main-
tenance practices. Most of these meth-
ods are feasible  and may be applied to
                 (continued page 6)

   AMMONIA CONTROL
       (continued from page 5)
smaller ammonia sources.
    Wet scrubbers are the most com-
mon control technique used for ammo-
nia with demonstrated efficiencies up to
99%. Scrubbers are commonly used by
the fertilizer,  livestock management,
and coke by-product  manufacturing in-
dustries.   Although  these industries
tend to be large sources  of ammonia,
wet scrubbers are available to treat air
emission  streams as  low as 1 cfm.
    Condensate strippers are the sec-
ond most popular control  device; how-
ever, in many cases they are consid-
ered as an intrinsic part of the  manufac-
turing process rather than an add-on
control device. Strippers remove am-
monia and return it backto the manufac-
turing process to  reduce  the need for
raw input materials. This recycling tech-
nique is commonly used in the fertilizer
industry and in refrigeration units.
    P2 techniques used to prevent am-
monia emissions include recycle, limit-
ing ammonia/urea use to control NOx
from combustion sources, capture de-
vices, and implementing good mainte-
nance practices. Capture systems play
a  critical  role in  collecting  ammonia
emissions for  treatment or recycle, as
demonstrated in coke by-product facili-
ties and refrigeration systems. These
same two source categories offer good
examples of good maintenances prac-
tices; that is,  they ensure that equip-
ment is maintained at a quality opera-
tional level to  minimize leaks and pro-
duction losses.
    For the post-combustion NOx con-
trol technologies of selective catalytic
reduction (SCR)  and selective non-
catalytic reduction (SNCR), when either
ammonia or urea is used as the reduc-
ing agent, ammonia may be emitted
with effluent steam (often referred to as
ammonia slip). This  condition can be
minimized by  good equipment opera-
tion practices and by limiting the amount
of  reducing agent  added to the amount
required to meet permit and operational
requirements.

         NOTEBOOK:
     HAP-PRO Version 2.0,
   Transferring Disk Copies

          Joe Steigerwald
_ CTC/OAQPS _

    The Hazardous Air Pollutant-Pro-
gram (HAP-PRO) is currently available
from the Downloading Area of the CTC
BBS.  The downloadable file is very
large (1.77 MB) and some users have
been having problems transferring it
from one PC to another.  (A two-disk
version of HAP-PRO Version 2.0 will be
made available  through the National
Technical Information Service (NTIS) in
the near future,  but it is not available
yet.) One may think that the program
could not be transferred from the com-
puter on which it was downloaded  un-
less you  were to generate your own
floppy  disks  from the  installed files.
However, there are better ways!
    The best way to transfer this or any
large file(s) between computers is to
use  PKZIP, the program you use to
expand files you download from  the
OAQPS Technology Transfer Network
Bulletin Board System (TTN BBS).
Please remember, the copy of PKZIP
thatyou downloaded from the TTN BBS
is free as long as you only use it to zip
and unzip files either going to or down-
loaded from the OAQPS TTN BBS.
    PKZIP has an option, the "-&"  op-
tion, to compress a large, or numerous
small or large files, onto  multiple dis-
kettes. The format for the command is:
prompt>PKZIP -& :zipfile
       filenamel filename2 ......
where:  =the  drive letter  of  the
       destination diskette
       zipfile =the name you assign
       the new compressed file that
       you create;
       filenamel, etc =the  names(s)
       of the file(s) you wish to
       compress or any 'wildcard'
(If your interested in PKZIP options, you
can get a complete list of PKZIP options
by  going  into a  directory that  has
PKZIP.EXE   in   it   and  typing:
prompt>PKZIP.  This will display the
format of  the  command options  and
indicate ways to see other options, in-
cluding the spanning option discussed
below.)
    As an  example, if you are transfer-
ring a file  called HAPPRO2.EXE,  and
you choose to call the zipfile "HP2.ZIP,"
(NOTE: the "ZIP" extender indicates a
compressed file) the PKZIP command
to compress it to the A drive would be:
prompbPKZIP -& A:HP2.ZIP  HAPPR02.EXE

    When executed,  the computer
would prompt you to put a diskette in the
A drive, write  as  much as  would fit,
prompt you for a second diskette,  and
so on  until the whole file was com-
pressed onto  the A drive.  Once  you
have a copy on diskette, you can put the
program/files on any PC by putting the
first diskette in the A drive (or whatever
drive letter is appropriate) and typing:

prompt>PKUNZIP :zipfile

In our example, this would be:

prompt>PKUNZIP A:PH2.ZIP

    The computer will examine the file
and prompt you to swap  diskettes.  Re-
member, you  need to have a copy of
PKZIP and PKUNZIP for this to work
and that the compressed file will expand
into whatever directory you are in when
you issue the command  unless  you
specify another, with a full path name, in
the PKUNZIP command after the zipfile
name.
    If you have multiple files to transfer,
you will also need to know and enter
each file name in the "-&" command or
use wild cards. The simplest way to do
multiple files is to  create a directory
containing only the files to  be  trans-
ferred and PKZIP. Then type:

prompt>PKZIP -& :filename *.*
This will transfer all files in the  current
directory to the specified drive.
    Another way, if both  of the comput-

    GENE CRUMPLER:
            OAQPS
     ENVIRONMENTAL
         ENGINEER

    As an  environmental  engineer
within EPA's Office of Air Quality Plan-
ning and Standards (OAQPS), Gene
Grumpier is currently leading the devel-
opment of  MACT standards  for the
wood preserving and the primary cop-
per  smelter industries.
Gene joined OAQPS four
years ago,   moving from
Washington,  D.C.   to
Durham,  NC in the pro-
cess.  He worked for the
EPA for  fifteen years in
Washington, first in the Of-
fice of Solid Waste (OSW)
for eight years and then in
the Office of Water for an-
other six.
    In OSW's Hazardous
Waste Program, Gene
helped the  EPA set up evaluation
methods  for chemical, physical, and
biological treatment processes for haz-
ardous wastes. He also authored the
1981 standards for hazardous waste
incineration.  During his tenure with
OSW, he contributed to almost 40 pa-
pers and presentations dealing with
hazardous waste.
   Following a  two-year stint as a
consultant  outside of government,
Gene joined EPA's Office of  Water.
While there, he concentrated on devel-
oping regulations for  incineration of
sewage sludge. He wrote and collabo-
rated on 18 papers and presentations
regarding  municipal wastewater
sludge during these years. While in the
Office of Water, he also contributed to
EPA's Ocean Incineration Regulatory
Program.
   Upon moving to the Durham office,
Gene began working in different regu-
latory areas.  He moved away from
waste incineration and now studies
other areas  of air pollution relating to
specific industries. The change in his
work assignments, he admits, was dif-
ficult but exciting. "I find it challenging,"
Gene said, referring to his new industry
areas. "When I came here, I came into
new areas. I felt it was a professional
challenge to get up to speed."
    Gene's ability to move to new areas
within EPA comes from his earlier work
as an engineer in the industrial sector.
Between 1963 and 1975 he worked for
three industrial  firms.  This included
work in the chemical and the synthetic
fiber industries. Also, from 1983 to 1985
he served as a project manager for an
                environmental con-
                sulting firm in Vir-
                ginia.   This varied
                experience, Gene
                explained, is part of
                the reason the EPA
                hired  him in  1975
                and again in 1985.
                "It  gives me a per-
                spective on what In-
                dustry has to deal
                with to meet  stan-
                dards,"hesaid, "and
                it allows me to have
a more rounded viewpoint."
    When asked what his lasting contri-
bution to EPA will be, Gene pointed out
that his work is far from over. However,
he does admit that his work with waste
incineration development and regula-
tion during the '80s was an important
project for him.  The importance of his
work  seems to  be a  key  element  in
Gene's decision to first join and then
stay with the  EPA. In 1975,  he was
looking "to do something of more signifi-
cance, (something with) more of a per-
sonal impact  on people."   The EPA
afforded him that opportunity.
    Outside of the EPA building, Gene
can be found on the golf course, practic-
ing a skill that he is "continually working
on." The Research Triangle Park area
(Raleigh, Durham, and Chapel Hill, NC),
he notes, allows him to lead a life-style
that is less stressful than the frantic
pace  of Washington, D.C.  His other
hobbies include photography. He does
his own darkroom work and is an active
member  of the Chapel  Hill Camera
Club.  Gene also tutors middle school
students in math, giving them personal
attention and one-on-one guidance.
    Gene  was  born and  reared  in
Roanoke, Va., and attended school at
Virginia Polytechnical Institute, where
he received a B.S.  in Chemical Engi-
neering. He has three grown children
and one grandchild.

ers involved have DOS version 5.0, is to
transport HAP-PRO by using the DOS
command "BACKUP" and then use the
DOS command "RESTORE". The easi-
est way is to use the BACKUP com-
mand on the 1.7MB compressed HAP-
PRO  file (or  any file  in the form
filename.ZIP) you download from  the
BBS.  (You can use the decompressed
files too but you'll need a lot more dis-
kettes.) Checkyour DOS 5.0 documen-
tation for the exact format and use of
this command.
    Finally,  an  individual called to say
that he was having trouble installing a
copy of HAP-PRO Version 1.0 which he
purchased from a commercial firm for
$50.00. We solved his installation prob-
lem and made  him aware of the CTC
BBS on the TTN where anyone can get
(for free) the latest versions of all CTC
software. The list of CTC software now
includes  the Surface Impoundment
Modeling System (SIMS),  the Landfill
Air Emissions Estimation Model (Land-
fill), the Hazardous Air Pollutant Pro-
gram (HAP-PRO), and the Solvent Al-
ternatives GuidE (SAGE). All are avail-
able for download without cost (except
for the telephone call) from the CTC
BBS. The CTC BBS is available via the
OAQPS TTN 24 hours a day (except
Monday from 8 - 12 A.M.).  See CTC
BBS on back page for more information.

(PS - Remember to do wnload the user's
manuals for the software, too.  Most of
your installation and use  questions will
be answered in there!)
