HAP-PRO VERSION 2.0
NOW AVAILABLE!
By Joe Steigerwald
CTC, ITG,OAQPS
Version 2.0 of HAP-PRO is now
available from the CTC BBS. The pro-
gram file and the User's Manual are
downloadable items within the Down-
loading Software and Other Items area
oftheBBS. The User's Manual is on the
BBS in an ASCII text format,
WordPerfect 5.x format, WordPerfect
6.0 format, and as an Envoy file. All are
in self-extracting format so just down-
load them, put them in a new directory,
go into that directory, and type their file
name from the prompt. The executable
file is large, 1.7MB, so use the highest
speed modem you can.
The primary purpose ofthe Hazard-
ous Air Pollutant Program (HAP-PRO)
is to assist permit engineers in review-
ing applications for control of air toxics.
HAP-PRO calculates the capital and
annual costs for up to six different vola-
tile organic compounds (VOCs) and
three particulate control devices, includ-
ing selected en-
gineering pa-
rameters.

By Bob Blaszczak
CTC Co-Chair, OAQPS
I'm sure glad I didn't make that "get out the CTC NEWS
on time" newyears resolution again. I'm not sure when you'll
be seeing this, but I know it's not January. (I sure hope it's no
later than February!) We're still getting use to our new
organization and trying to figure how to do more with less.
Getting the CTC NEWS out during this turmoil has been a real
chore. It seems like I'm being devoured by my workload
instead of empowered to get it done. Oh well, I'll grow from
the experience.
For the fifth time in the seven years I've been with the
Office of Air Quality Planning and Standards (OAQPS), I (and
the CTC) have moved. We're still in the same building, just
a different floor with a different view. Although moving is
getting to be the routine thing to do every year or so, it's still
drudgery and very time consuming. The only good thing
about it is that it forces an old pack rat like me to cleanup. The
move did cause some disruption of CTC HOTLINE service
and we sincerely hope this did not cause you any pain.
Otherwise, as far as you're concerned, nothing has changed
except our regular mail drop (now MD-12). So, make a note
of it and be sure to use it when writing the CTC. We have also
added a second FAX line (919/541-0361) to improve access
the Air and Energy Engineering Laboratory (AEERL) part of
the CTC. The old FAX number (919/541 -0242) still works and
connects you with the OAQPS side ofthe CTC. Feel free to
use either number. We'll make sure that it gets to the right
person. 6
"Centre de Control Tecnologico; Podriamos ayudarle?"
That's the greeting our Spanish speaking friends will hear
when calling the CTC HOTLINE in the near future. (That
translates to "Control Technology Center: can I help you?")
The CTC is becoming an active player in the Mexican Border
Initiative, a program to clean up pollution along the Mexican
border. A Spanish speaking CTC HOTLINE and bulletin
board are under development. We hope to have them up and
running by late spring. Although targeted to promote environ-
mental improvements along the Mexican border, the new

inorganic vapors and participates).
HAP-PRO also includes an expert
review system for the design of thermal
incinerators, catalytic incinerators, and
carbon adsorber systems. The pro-
gram reviews the design results gener-
ated, makes recommendations for
changes, and allows easy evaluation of
design sensitivities.
Even though the version number
made a large jump (from 1.2 to 2.0) the
changes in the model were mostly inter-
nal. The following changes were made
from version 1.2 to version 2.0:
- The system was redesigned for im-
proved accuracy of calculations and
better performance.
- The data entry screens were modified
to be consistent for all data groups.
- The system was modified to allow
multiple control devices to be associ-
ated with a stream. This allows users to
run calculations on different control de-
vices for the same stream and HAPs
and compare the results.
HAP-PRO version 2.0 is available
through the CTC BBS to anyone who
wants to download it. However, the
CTC will make the model available on 2
high density 3.5 inch diskettes to indi-
viduals in State or local air pollution
control agencies if they are unable to
download the files from the CTC BBS.
The model will also be available from the
National Technical Information Service
(NTIS) for a fee in the near future. Both
the BBS version and the diskette ver-
sion examine your harddrive upon in-
stallation to see if you have an older
version of HAP-PRO on your system. If
it finds HAP-PRO version 1.2, you will
be asked if you need to save any data
file you may have already created. If it
finds an older version, you will be
prompted to either call the CTC for the
appropriate files to upgrade it to version
1.2 orto allowthe installation program to
overwrite these older files. Remember,
if you updated to version 2.0 from a
version prior to version 1.2, some exist-
ing data files may be lost or corrupted.
Either way, it would be prudent to make
a backup copy of any important HAP-
PRO data files you have before you
install version 2.0 over any older ver-
sion except 1.2.
After the installation is complete,
enter HAP-PRO at the DOS prompt to
execute version 2.0. The hardware
requirements for using the HAP-PRO
model are not very stringent. They are:
an IBM PC/XT/AT or compatible; 515K
minimum free RAM; hard disk with a
minimum of 4.2 megabytes of free stor-
age space for installation; mono-
chrome or CGA/EGA/VGA color moni-
tor; and MS-DOS version 3.1 or
greater. E9

Hotline will accept calls from all Spanish
speaking people. We're also in the
process of identifying key documents
that need to be translated into Spanish
and technical assistance/guidance
project needs. Stay tuned for additional
developments.
The Federal Regulation Data Base
has proven to be a very popularaddition
to the RACT/BACT/LAER Clearing-
house (RBLC) bulletin board. It pro-
vides quick access to summary infor-
mation on Federal emission standards
(NSPS, NESHAP, and MACT) in a for-
mat similar to that used for the source
specific (traditional) RBLC data bases.
We will be adding a browse function in
the near future to simplify viewing the
regulations. We are also inviting State
and local agencies to input their signifi-
cant regulations. If you have any sug-
gestions for additional improvements,
please let us know.
As is the tradition, this January edi-
tion of the CTC NEWS includes a CTC
product ordering form. Our resources
are limited. So, please order only what
you need. Besuretoincludeyourreturn
address and phone numberwhen plac-
ing your order. Also, note that the

DANIEL RETIRES
The Control Technology Center
(CTC) recently lost the services of a
valued staff member. Bobby Daniel,
whom many of you would recognize by
his sultry southern drawl, retired on
January 3,1995, from the EPA. He has
been with the EPA in the Air and Energy
Engineering Research Laboratory for
25 years, including the last 4 years as a
member of the CTC staff.
. His experience, patience, and wis-
dom have greatly contributed to the
success and growth of the CTC. Bobby
accepted each call as a new challenge
and endeavored always to give the
caller complete and accurate service.
He said, many times, that he enjoyed
providing this service to government
and private industry agencies.
Although Bobby broughtto the CTC
expertise in many areas of pollution
control technology and research, his
target areas have been asphalt emis-
sions and advanced volatile organic
compound (VOC) control technology
evaluation. Bobby's research studies in
asphalt emissions have become recog-
nized authoritative documents.
Bobby joins his wife, Martha, in
retirement. He enjoys spending time
with his son and best friend, Thomas,
and his daughter, Deborah. Besides
being an avid golfer, he is a dedicated
fan of Duke University football and bas-
ketball.
Bobby, we wish you good luck, hap-
piness, and a monthly "hole in one"
in the coming years! E3

REGULA TIONS DA TA
BASE NOW A VAILABLE
TO STATE AND LOCAL
AGENCIES
By Jo Ann Kerrick
VIGYAN
Do people askyou about your State
or local air pollution regulations? Per-
haps it's just one or two special rules
that address a source not yet regulated
by others or set important benchmarks.
The RACT/BACT/LAER Clearinghouse
(RBLC) has a new data base that may
help you respond to these questions
more effectively.
In November 1994, the RBLC
added a data base that contained sum-
maries of regulations that were enacted
at the federal level in response to the
Clean Air Act and Amendments. Start-
ing in January 1995, State and local
agencies can add summaries of their
own rules to the data base, making this
information available to all TTN users.
You may include all your rules or just
those that you feel may be of interest or
that you want to share with others. How
many and which rules you enter are up
to you.
Adding and updating youragency's
regulations is easy. To get started all
you need is a password to access the
data entry module of the regulation data
base. This module uses the same
menu-driven system that you know
from the RBLC's control technology
determination data base. It includes
context-sensitive on-line help at all
menus and prompts to assist you with
your input. If you would like to enter

WILLIAM MAXWELL -
CTC EXPERT ON
EMISSIONS FROM
UTILITIES
By Janet Erwin,
Acurex Environmental
CTC callers needing expert advice
concerning emissions from utilities are
likely to be directed to William Maxwell.
His current work as the Project Lead for
the Utility Air Toxic Study Report to
Congress puts him on top of ongoing
research to determine possible health
effects resulting from hazardous air
pollutant emissions from utilities.
Originally from the Midwest, Bill
earned his B.S. in Civil Engineering
from Kansas State University in 1969.
After serving 2 years in the Army under
the ROTC program, he returned to Kan-
sas State to begin working towards his
Masters in Sanitary Engineering, which
he was awarded in 1973.
Bill's degree prepared him for his
work as an environmental engineer at
the Midwest Research Institute in Kan-
sas City. There, as an EPA contractor
working under the New Source Perfor-
mance Standards (NSPS) contracts, he
performed field testing at various indus-
tries, including power plants and pulp
mills. These
projects were part
of EPA's continu-
ing efforts to carry
out work under the
Clean Air Act.
Bill's work un-
der the NSPS con-
tracts brought him
to Durham in 1979,
where his contin-
ued work as an
EPA contractor
eventually led to his
coming on board
with EPA in 1985.
He comments on
his 9 years with
EPA, "It doesn't seem like it has been
that long." He further commented that
he enjoys the people he has the oppor-
tunity to work with, and that his job
provides him, "achancetoattempttodo
something good."
Well, he must have been success-
ful in his attempts! In March of 1992, Bill
was honored with a Bronze Medal for
Commendable Service for his work on
the small boiler NSPS team developing
standards of performance for small in-
dustrial/institutional/commercial boil-
ers. Again in November of the same
year, he was recognized with another
Bronze Medal. This one commended
his work on the source
category list project
team, on which he con-
tributed to the develop-
ment of the list of
source categories for
which Section 112
standards would be re-
quired under the Clean
Air Act Amendments.
Last June, Bill's out-
standing efforts were
recognized once more.
He was awarded a third
Bronze Medal for his
work on the medical
waste incinerator tech-
nical program and his
contributions to the development of the
technical background information nec-
essary to develop standards of perfor-
mance.
At work, Bill spends time determin-
ing whether or not utilities need to clean
up their act. In his free time, however,
he enjoys tennis, camping, and helping
his two boys, both scouts, with their
skills and sometimes their homework.
Although Bill claims he doesn't have any
upcoming travel plans, he enjoys re-
turning to the Midwest to visit his family,
or breathing in some coastal air at Top-
sail or Myrtle Beach.

to access the edit module. This module
is password-protected, so enter your
password at the prompt. The system
verifies your password and displays the

The regulation data base is orga-
nized so that a rule is associated with
the type of facility whose pollutant emis-

This facility is referred to as the affected
facility. Information at the regulation/
affected facility level includes the rule
number (as assigned by your agency),
rule status, statutory basis for emission
limits, proposed and effective dates,
references to supporting technical
documentation, and explanatory notes.
Especially important is a telephone
number for a contact at your agency
who is knowledgeable aboutthe regula-
tion.
Each affected facility consists of
one or more processes that are regu-
lated by the rule. Data at the process
level includes process type, SCC code,
and additional notes for details about
the process itself. Each process, in
turn, consists of information on one or
more pollutants and the emission limits
required by the regulation. Pollutant-
level information includes details about
add-on equipment and/or pollution pre-
vention methods that can satisfy the
rule; estimated capital costs and opera-
tions and maintenance costs; and cost
effectiveness in dollars per ton.
Try to fill in as much information as
possible when you are adding a new
rule, and be sure to use standard terms
and abbreviations. Other users inter-
ested in your agency's rules will be
using the query module to access this
information. Complete and consistent
data help insure that searches with any
of the allowable fields produce the de-
sired results. The searchable fields are
the same ones used in the determina-
tion data base, except for a few fields
that do not apply to regulations (e.g.,
AIRS ID).
The RBLC is enthusiastic aboutthe
federal and State regulation data base
and hope you will take advantage of this
new capability. As States enter their
own information on key rules, both fed-
eral and State rules will be available - all
in a single data base. Call EPA at
(919) 541-2736 to get a password from
the BLIS System Administrator, and get

EQUIPMENT CLEANING
COMPOUND
SYNOPSIS
Numerous manufacturers of clean-
ing compounds are continuing to qualify
to the new Military Specification, MIL-C-
87937B Cleaning Compound, Aero-
space Equipment. This specification
developed by San Antonio Air Logistics
Center (SA-ALC), Kelly AFB, Texas,
establishes the requirements for biode-
gradable, water dilutable, environmen-
tally safe cleaning compounds for use
on Air Force equipment (aircraft, en-
gines, and aerospace ground equip-
ment). Environmentally safe means no
ODC or EPA 17 materials. The clean-
ers fall into four classes:
-Type I is a terpene-based solvent
emulsion, water-dilutable cleaning
compound.
-Type II is any water dilutable cleaning
compound with no flash point.
-Type III is a gel-type cleaning com-
pound.
-Type IV is a heavy duty, waterdilutable
cleaning compound with no flash point.
Independent laboratories, manu-
facturers, and Department of Defense
(DOD) agencies conducted extensive
laboratory tests, reformulations, and
field tests during the writing of this
specification. There are currently
cleaners qualified as Types I, II and III.
Manufacturers are currently testing
material to qualify as Type IV, with
qualification expected by the end of
1994. All are biodegradable cleaners
that meet materials and performance
criteria including:
- Corrosion testing on AZ31B magne-
sium, 2024 and 7075 aluminum, 1020
steel, stainless steel, titanium, and alu-
minum-lithium.
- Having no effect on painted surfaces
(enamel and polyurethane for Type I
only) or acrylic plastics.
-Compatibility with polyimide wiring in-
sulation.
-Removing oil, hydraulicfluid, and other
soils from surface with no streaking,
blistering, or discoloration.
-Containing no known toxic or carcino-
genic substances.
-Biodegradability, the EPA biodegrad-
able acceptable rate is 70 percent within
28 days. Type I is 75 percent biodegrad-
able within 28 days, while Types II, III,
and IV are 85 percent biodegradable
within 28 days.
-Cleaning efficiency (passes a stan-
dardized cleaning test developed by
SA-ALC and an independent testing
lab).
BENEFITS/LIMITATIONS
Mr. Gus Zachariades, chemist for
the preparing and qualifying activity,
SA-ALC/SFTT, stated, "There are cur-
rently several good cleaners qualified to
Types I, II and III, which can be found in
the Qualified Products List (QPL).
Many more compounds are in the pro-
cess of qualifying to all types."
MIL-C-87937 cleaning compound
benefits include:
-Ability to remove carbon, solidified
grease, gelled oil, and othertypes of soil
in any application method such as cold
dip tanks, sprayers, foamers, hand-
wipe, or brushed on application.
-Type I cleaners remaining effective for
up to two months in dip tanks by simply
skimming off the separated oil and re-
plenishing the lost fluid.
-Reusing diluted cleaner solutions, from
Type I cleaners, when recycled through
an oil-water separator.
-Requiring rinse water at room tempera-
ture rather than heated water.
-Cleaning compound with demon-
strated biodegradability.
-Documented materials compatibility.
MIL-C-87937 cleaning compound
limitations include:
Editors Note: This article was submitted by the U.S. Air Force and reflects their
experience and satisfaction with new cleaning agents. EPA encourages the
development and use of performance based specifications and more environmen-
tally friendly materials that prevent or minimize pollution. However, use of these
materials as part of a program to comply with environmental regulations must be
considered on a case by case basis.
Control Technology Center
The CTC NEWS is a quarterly publication of the
U.S. EPA's Control Technology Center (CTC).
The CTC is an informal, easy-to-use, no cost,
technical assistance service for all State and
local (S/l) air pollution control agency and EPA
Regional Office staffs. For others, some ser-
vices may be on a cost reimbursable basis. The
CTC offers quick access to EPA experts and
expertise via the CTC HOTLINE and the CTC
Bulletin Board, and in-depth technical support
through source specific Engineering Assistance
Projects or more generic Technical Guidance
Projects. The CTC is operated by the Air and
Energy Engineering Research Laboratory, Of-
fice of Research and Development, and the
Emission Standards Division, Office of AirQual-
ity Planning and Standards in Research Triangle
Park, North Carolina.
If you have any air pollution emission or
control questions, or would like more information
about the CTC and the types of technical assis-
tance available, CALL THE CTC HOTLINE!

-The necessity of diluting with water.
-The necessity of rinsing aircraft or
parts with cold water to prevent leaving
a residue or stain.
-Ferrous alloys that may flash rust may
require a protective coating or a rust
inhibitor in the rinse water.
- No standard water-dilution ratio. This
ratio varies from manufacturerto manu-
facturer and type of application. Spe-
cific applications figures depend on
parts cleaned.
-Type I cleaner's corrosive effects on
soft metals (such as indium).
-A potential adverse effect on cleaning
properties caused by the quality of local
water.
-Costing more than previous non-biode-
gradable cleaners.
MIL-C-87937 is approved for aero-
space ground equipment and certain
airframes when approved by the appro-
priate Single Manager for the equip-
ment involved. John King, Chief of the
Materials Engineering Section at SA-
ALC, stated "This specification is com-
munication of an effort initiated over six
years ago by the Air Force Civil Engi-
neering Support Agency at Tyndall
AFB, FL. Undertheirdirection, overSOO

various cleaners were tested for perfor-
mance and MIL-C-87937 is the result-
ant. The SA-ALC portion of this initiative
was to develop a specification from the
best of the best and originally only one
type of cleanerwas planned. As condi-
tions and requirements changed, four
different types have resulted."
DOCUMENTATION
Technical documentation concern-
ing MIL-C-87937 cleaning compounds
is available from Brian Ballew, (See
below.)
ENVIRONMENTAL
Lt. Robert Reed, Environmental En-
gineer, SA-ALC, stated, "MIL-C-87937
is a masterful combination of perfor-
mance and environmental consider-
ations. It is one of the first documents
from the Air Force in which environmen-
tal considerations were given equal
weight with that of performance." Many
local, State, and base regulations pro-
hibit dumping some cleaners into the
waste treatment facilities because al-
though a cleaner may be biodegrad-
able, the soils being removed may not.
