THE LOCATING AND ESTIMATING . . . SERIES ON TOXIC SUBSTANCES

Styrene Report Available —

EIB has recently produced another
report in its well-known "L&E" series
on toxic air pollutants, Locating And
Estimating Air Emissions From
Sources Of Styrene: Interim Report,
EPA-450/4-91-029. This report, the
24th in the series, is to assist in
locating possible sources of air toxics
and then making preliminary estimates
of the emissions produced by these
sources.

The Styrene report describes
processes, variations and release points
within these sources, along with
available emissions data and emission
factor estimates that indicate the
potential for the release of air toxic
compounds from styrene operations.
Overviews are also provided of
procedures for source sampling and
analysis of emissions from these
sources. The report is being released
as an interim document, pending

incorporation of further expected test
data. OAQPS's Emission Measure-
ment Branch, on behalf of EIB, is
currently testing several unsaturated
polyester resin fabricators of cultured
marble bathroom fixtures, and when
the results are available, a final report,
with these data, will be published.

Single copies of the report are
available from EPA Library at MD-35,
Research Triangle Park, NC, 27711 or
by calling (919) 541-2777 or (FTS)
629-2777. The report is also available
from the National Technical
Information Service (NTIS) for a fee,
NTIS stock no. PB92-126788.

A list of all the air toxic emission
reports in this series is included in our
brochure, "Tools For Estimating Air
Emissions Of Criteria And Toxic
Pollutants". For further information
on the Styrene report, or for copies of
the Tools brochure, contact Anne Pope.

{FACTS ABOUT AP-42 DATA QUALITY REQUIREMENTS }

How can you tell if your source
test data would be helpful in AP-42
section development? Of course, it
would be great if every emission factor
in AP-42 had our highest quality
rating, an "A". If we discarded all
information that is less than perfect,
we wouldn't need the A through E
quality rating system, but AP-42
would then be a much smaller book.

All data must pass common sense
and reasonableness tests. Beyond that,
here's what we scrutinize when
deciding what to use in an A rated AP-
42 section:

1) We must have full document-
ation of the process tested, the control

EIB's Inventory Guidance And
Evaluation Section and the National
Air Data Branch announce the
publication of the National Air
Pollutant Emission Estimates, 1940 -
1990, EPA-450/4-91-026, November
1991. This year's report contains

devices and their condition, the
equipment used to perform the test,
and load/operating rates;

2) The test methods must be
established and approved;

3) A formal quality assurance
program must have been in effect and
evidence provided on how it was
successfully followed; and

4) Information must be provided
on how representative the given
source is of the population.

The factor rating system we use is
discussed in more detail in the
introductory pages of AP-42 and in
EIB's procedures guidance document on
how to develop AP-42 sections. The
standards that tests must meet to gain

several useful innovations. Because of
a new method for making early
estimates, the report is appearing
considerably ahead of schedule. Also,
it now features emission projections to
the years 2000 and 2010 for SO,,
NO,, NMOCs and CO. Trends are

an "A" rating are tough. For many
source categories, there may be few
available data of such quality, or none,
yet AP-42 users still need the
information. In these cases, the above
criteria become a “low hurdle". Less
formalized and stringently documented
data may still be found useful for
approximations, and the quality ratings
then assigned will be commensurate
with the quality of the input
information. We still need to hear
from anyone having possibly useable
emissions data. If you have questions
on specific data criteria, please contact
someone on the EFMS staff here at

NEW VERSIONS OF XATEF AND SPECIATE

Version 1.4 of SPECIATE, the
VOC/PM Speciation data base
management system, and Version 1.2
of XATEF, the Crosswalk/Air Toxic
Emission Factor data base
management system, are both now
available. These systems are for use
on an IBM‘TM compatible personal
computer. Each system is distributed
on one 5.25" high density disk, and
both may be downloaded from the
CHIEF Bulletin Board.

SPECIATE contains 700 species
profiles, for both volatile organic
compounds (VOC) and particulate
matter (PM). By applying the species
profiles to either total VOC or PM
emission estimates, then either the
weight percentage of specific VOCs or
the elemental composition of PM can
be estimated for the source categories
covered in the manual. SPECIATE
presents data by compound and by
source category, and the data base is
updated annually. The Volatile
Organic Compound (VOC)Particulate
Matter (PM) Speciation Data System
User’s Manual, Version 1.4, EPA-
450/4-91-027, accompanies the disk
and explains the uses and limitations

of the data and the use of the data
management software.

SPECIATE users will need an
IBMTM compatible personal computer
with MS-DOSTM version 3.0 or later,
640 KB free RAM, a fixed disk with at
least 8 MB of storage, and a high
density 5.25" second disk drive.

XATEF contains toxic air
pollutant/source crosswalk data and air
toxic emission factors. The crosswalk
data identify the types of compounds
that may be emitted from a source
category. Crosswalk indicates the
possible pollutant/source associations,
based on literature information,
existing inventories and other available
data. The crosswalk data in XATEF
include pollutant names, CAS
numbers, Standard Industrial
Classification (SIC) codes, and
emitting Source Classification Codes
(SCC). XATEF also contains 7600
emission factor citations for over 300
compounds and more than 500 source
categories. The data base is updated
annually. The Crosswalk/Air Toxic
Emission Factor Data Base
Management System User's Manual,
Version 1.2, EPA-450/4-91-028,
accompanies each disk and explains the

uses and limitations of the data and the
use of the data management software.
XATEF users will need an
IBMTM) compatible personal computer
with MS-DOSTM version 3.0 or later,
640 KB free RAM, a fixed disk with at
least 20 MB of available storage, and a
high density 5.25” extra disk drive.
Both of these systems are designed
for easy access and retrieval of
emission estimation data, by pollutant
or source description. The purpose of
XATEF and SPECIATE is to assist
air pollution control agencies and
others who are interested in locating
potential sources of air toxics and in
making preliminary estimates of the
emissions from these sources.
XATEF and SPECIATE are
available to government agencies and
by contacting Anne Pope at the
Newsletter. Both systems can also be
downloaded from the CHIEF Bulletin
Board. SPECIATE and XATEF soon
will be available through the National
Technical Information Service (NTIS)
for a fee. No NTIS stock numbers
have yet been assigned to them.

Anne Pope at the Newsletter, 4

DIRECT ASSISTANCE TO STATES IN PREPARING 1990 03/CO INVENTORIES

EIB has issued a Work
Assignment to provide direct
assistance to state and local agencies as
they prepare their 1990 03/CO
inventories. This effort will make
assistance available in the use of EPA
software, emission inventory
techniques, emission factor selection,
and general problem solving, and it

can be in the form of telephone contact
or direct onsite assistance. The EPA
Regional Offices are coordinating this
support for each of their States. The
CHIEF Bulletin Board will be used to
share information of general interest
that may be useful, and all state and
local agencies are encouraged to check
CHIEF regularly for the latest

information on preparing 1990
inventories for ozone and carbon
monoxide. For more details on
contractor assistance with the
inventories, contact Sharon Bruno

EIB RELEASES AIR CHIEF CD-ROM

EIB's newest emission estimating
product, the Air CHIEF Compact
Disk-Read Only Memory (CD-ROM),
is now available after months of
preparation. The Air CHIEF offers on
one small disk the literally thousands
of paper pages contained in some of
EPA's most widely used and asked for
documents. Air CHIEF contains:

— the entire contents of the AP-42
series,

— all of the Locating
Estimating... reports,

— the VOC/PM Speciation data base
management system, SPECIATE, and
— the Crosswalk/Air Toxic Emission
Factor data base system, XATEF.

Air CHIEF is a powerful data
retrieval tool. It's designed to allow

And

easy access and retrieval of emission
estimation data, by pollutant or source
description, and it can be scanned and
searched in fine detail. Information
searches can be very broad or tightly
focused. For example, coal
combustion is mentioned in about
2000 "records", or places, on the disk.
Asking specifically for arsenic from
bituminous coal combustion in utility
boilers will lead the user to 8 records.
Also, all chemical elements and
compounds mentioned on the CD that
have Chemical Abstract Services
numbers can be scanned and searched.
Air CHIEF and its user's manual
will be updated annually, beginning in
Spring 1992. Single copies of the CD

can be obtained by writing Anne Pope
at the Newsletter. Shortly after the
Spring '92 revision, Air CHIEF will
be available through the Government
Printing Office (GPO). GPO expects
to vend the disk for about $13.00, a
Noticeable economy over buying paper
copies of it all (~$900.00).

Users need an IBMTM) compatible
personal computer with EGA or VGA
monitor, MS-DOSTM version 3.0 or
later, 640 KB of free RAM, 2 MB
expanded memory, a CD-ROM drive,
interface card, and Microsoft DOS CD-
ROM Extensions (MSCDEX). Users
can help by sending any comments or
suggestions regarding Air CHIEF to

SECOND ANNUAL EPA/AWMA CONFERENCE ON
EMISSION INVENTORIES BEING PLANNED

After the highly successful first
emission inventory conference last
September (see the October
Newsletter), EPA and the Air And
Waste Management Association are
planning a repeat effort. J. David
Mobley, Chief of the Emission
Inventory Branch (EIB), will be
general conference chair. The meeting,
scheduled for October 19 through 22,
1992 will examine emission
estimation tools, current research and

issues, and possible problem areas for
future inventories. On the 19th, there
will be a one-day training course on
inventory and estimation
fundamentals, and actual conference
proceedings will begin the 20th.

The call for papers has been
issued, and everyone interested in
speaking at the conference should
contact EPA's Larry Jones or John
O'Connor of Radian (sce below under
“Upcoming Meetings And

Conferences"). Session topics and
other details are still being configured,
As soon as possible, the latest
information on the specialty
conference will be made available
through the CHIEF bulletin board,
this Newsletter and the AWMA
Journal. Watch for it. (Elsewhere in
this Newsletter, you can find out how
to get on the bulletin board.) 4

FULL REVISION OF AP-42'S STATIONARY SOURCE VOLUME

The Emission Factor And
Methodologies Section has undertaken
a complete update of the stationary
source volume of AP-42 this fiscal
year. Much of the material in our
recent Supplement D, announced in
the last Newsletter, was the result of
the initial six-month review and
revision of AP-42 as mandated by the
Clean Air Act Amendments. But
we're not stopping there. Over the
next several months, our efforts will
encompass the review and revision of
the entire stationary source volume.
The work will also add to AP-42 any
sufficiently representative emission
factors we can develop for air toxics,
greenhouse gases, or stratospheric
ozone depleters, as well as new
information for the six criteria

Is WELL UNDER WAY

pollutants.

Source test programs will be
planned, to resolve any data
deficiencies we can identify.

Here's the approximate schedule
we are planning to follow:

Data gathering: Through February
1992.

Data evaluation: Through March
92.

Revisions and documentation
drafts: Through mid-May ‘92.

Internal reviews: April - June '92.

External reviews and placement of
drafts on CHIEF: May and June '92.

Acceptance and resolution of
comments: July - September '92.

Publication of Supplement E of
AP-42: November "92.

This newslettey is printed on recycled paper.

Resolution of more complicated
issues and completion: May '93.

Completion of this phase:
November '93.

As you can see, there will likely
be a Supplement F before we are fully
through with the "wholesale" revision.
After that publication, we expect to be
folding all the pieces of AP-42 into a
new edition. The ingredicnts of this
Fifth Edition will still look familiar in
format and content, but the increasing
amounts of both new and revised
material may lead to the chapters'
being published as separate reports. In
this form, users not interested in the
entire AP-42 will be able to get copics
of only the parts they need.

Work assignments for various
chapters in AP-42 have been assigned

The inventories for these 24 areas

will be slightly revised by OMS, to
exclude the portions which are in
attainment of ozone and carbon
monoxide standards (as listed in the
November 6, 1991 Federal Register
notice titled "Designation Of Areas
For Air Quality Planning Purposes").
The New York area will probably be
the first area examined.

OMS also is developing specific
nonroad inventories for all serious and
above ozone (0.160 ppm and greater),
and for all moderate-2 and above CO
(12.8 ppm and above) nonattainment
areas. These new inventories can be
incorporated into the areas’ 1990
inventories with little effort. General
guidance will also be developed on
how to compile nonroad inventories
for other areas. For further
information on these matters, contact
Greg Janssen at OMS, commercial
phone (313) 668-4285/FTS 374-8285.

3 — Surface Coal Mining - Section 234 of the 1990 CAAA requires that emission factors and models applicable to
surface coal mining activities be reviewed and revised, to assure that they don't overpredict emissions. EIB, with the Source
Receptor Analysis Branch, is planning a multiyear program to meet the CAAA provision, and we will begin source testing
this Summer of high priority surface coal mining operations. For more information, contact Dennis Shipman at the
Newsletter, commercial phone (919) 541-5477/FTS 629-5477.

9% — Optical Remote Sensing And Measurement - An AWMA specialty conference will be held in Houston 5-8
April on the regulatory requirements and proper specifications for using this technology in pollution control programs.
Regulatory program managers, plant operators and others can meet with legislative staffs to discuss one another's needs and
abilities. A one-day course will be given on "The Basics Of Remote Sensing Of Atmospheric Pollutants". The Texas Air
Control Board and Chemical Manufacturers Association are cosponsors. For more information, see "Upcoming Meetings...".

% — O;/CO Inventory Preparation Plan (IPP) Status - The Regions have received draft versions of all 43 IPPs
due to them by 1 July 91, but only 19 have been submitted as final. Of the 19, only 3 have been approved (AL, FL & GA).
EIB will be working with the Regions and discussing their strategies for dealing with the problems. Timely submission of
the IPPs is critical to the review process, since final emission inventories are due by mid-November. For more information,
contact Lee Gabele at the Newsletter, commercial phone (919) 541-5292/FTS 629-5292. #

to several contractors. Each contractor
has to 1) gather all available existing
data, 2) review these data, 3) propose
revised factors and any other section
improvements, 4) distribute the revised
proposals to external reviewers, 5)
incorporate any comments, and 6)
prepare final AP-42 sections and
background documentation. In
addition, each contractor will propose a
source testing strategy for future years.
We would appreciate hearing
from our readers - state and
local agencies, industry,
consultants and others - about
all aspects of this process. We
want your comments. or
critiques of existing sections,
but more importantly, you can
also. provide test data,
volunteer to be a_ reviewer,

volunteer your plant for
testing, or assist in other ways
you think would be useful. We
will base operations on priority and
perceived need on our part.

Other significant activities
overlaid on this operation make it even
more complicated. For example, we
are including several improvements in
the consistency of AP-42. These
relate to VOC reporting consistency,
PM-10 data, and general information
on toxics, CO,emissions, methane,
etc. We plan also to add Source
Classification Codes into the tables
and to make other changes to facilitate
the computerized version on the Air
CHIEF compact disk. We also have
active cooperative test programs going
with the petroleum, wood products,

crushed aggregate, and asphalt batching
industries, and others.

We also plan to update the Air
CHIEF CD-ROM annually each
March, to include the most recent new
and updated emission factor material
we have, for AP-42 as well as for the
other data bases on the compact disk.

Please give us a hand with all of
this work. If you have data, would
like to be a reviewer, or help in any
other way, get in touch with us. You
may send data and other information,
in writing please, to the person in
EFMS who is responsible for the
specific chapter in AP-42. If you send
test data or literature citations, please
include sufficient information for it to
be evaluated. For example, test data
should specify methods, process data
taken at the same time, etc. 4

HAPPY NEW YEAR FROM THE CLEARINGHOUSE!

As we roll into CY 1992 (The
Year Of The Emission Inventory!),
let's have a quick review of some
important things that transpired in the
Emission Inventory Branch in ole '91.
The Newsletter press run moved past
4000 copies, the CHIEF bulletin board
began, AP-42 Supplement D was
printed, and several emission factor and
inventory guidance documents were
published. And as detailed below, EIB
has used modern electronic
prestidigitation to put many thousands
of pages of guidance material onto one

neat 12 cm plastic disk, the Air
CHIEF CD-ROM. All these
documents are on the CHIEF Bulletin
Board, too. Also, we began testing a
considerable number of source types,
such as wood products and crushed
stone, to get data for developing new
emissions factors, especially for
priority data gaps in the AP-42 series.
This testing will continue for some
time, and we expect it to bear fruit in
1992 in one of our largest projects, the
complete review and revision we've

begun of the AP-42 stationary source
volume.

We are always interested in the
needs of our readers and in your views
on the work we do here at the
Emission Inventory Branch. Write, E-
mail or call us with your questions,
suggestions and opinions, and share
what you know with the emission
factor and inventory community by
submitting articles to this Newsletter.
The deadline for the next issue is 1
March. Thanks for all your help in
the past, 4
