TABLE 2-7. Continued - NOTES
a Both boiler capacities and throughputs must be reported to NEDS for all
boilers.
b This emission factor is an approximation. Particulate emissions from
residual oil combustion can be more accurately estimated from the equation
LB/1000 Gallon = 10S + 3. See AP-42, page 1.3-2.
c The emission factor(s) are non-standard. The factor(s) are derived from
AP-42 data for another similar source category.
d The emission factor(s) are not from AP-42. The factor(s) are from other
EPA documents, State data, or other miscellaneous sources.
e This emission factor is an approximation. Particulate emissions from
waste oil combustion can be more accurately estimated by the factor 75 A,
where A = weight (%) percent of ash in the waste oil. See AP-42, page
1.11-1.
f Fugitive emissions occur from numerous locations within industrial facili-
ties, as of 1978, most of these sources have not been fully characterized.
To allow these fugitive sources to be represented in NEDS, common SCC
codes have been developed. These codes should be used in addition to the
main process SCC codes associated with the facility. Specific fugitive
emissions that have been characterized are also contained in this table.
9 These emission factors are from an earlier edition of AP-42. This is an
obsolete process. The last channel black plant in the U.S. closed in 1976.
h These emission factors are from an earlier edition of AP-42. This is an
obsolete process. The gas furnace process is being phased out in the U.S.
1 Manufacture of inorganic pigments is classified under SCC 3-01-035-*'*.
J For molded and fabricated rubber and plastics products, see SCC 3-08-***-**,
3-30-002-**, and 4-02-002-**.
^ This emission factor is an assumed average value from a range of values
given in AP-42, Table 5.17-2.
"1 Also applies to the sulfur recovery plant at petroleum refineries and
natural gas production fields.
m
See 3-01-301-** for other Chlorobenzene process codes.
n Grain processing and milling are included in SCC's 3-02-007-** thru
3-02-008-**. For grain elevators, see SCC 3-02-005-**, 3-02-006-**, and
3-02-031-**.

ฐ Units refer to amount of grain processed through each operation. If only
the total amount of grain received or shipped is known, see AP-42, TaDle
5.4-2 for typical ratios of tons processed to tons shipped or received.
P The particulate emission factor is on emissions at the inlet to the baghouse
or other control device. Indicate the control device and efficiency to
properly estimate the actual emissions.
Q Codes 3-03-003-09, -10, and -11 represent individual operations within
this SCC (3-03-003-07).
r These emission factors are from an earlier edition of AP-42. The currant
version of AP-42, Fourth Edition, no longer reports emission factor! s) for
this process.
s This emission factor is a weighted average of values given in AP-42, Table
7.3-2.
t Represents total CO generated, report control equipment as 022 for CO
boiler or 060 for process gas recovery to properly, account for actual
emissions.
u Represents total CO generated, report control equipment as 022 for CO
boiler or 023 for flaring to properly account for actual emissions.
y These emission factors are derived from AP-42 data. A-units adjustment has
been made to the AP-42 data. See AP-42, Table 7.6-1.
* Apply for all metallic minerals except as noted. Low moisture ore is de-
fined as having less than 4 percent moisture content by weight for ore
entering the primary crusher. High moisture ore has over 4 percent by
weight.
* Emission factor does not apply to bauxite ore.
y Emission factor does not apply to drying of titanium/zirconium sands. See
SCC 3-03-012-** for titanium processing.
2 Calculated from emission factors given in Table 7.9-2, Footnotes b-e.
aa This emission factor is an approximation. To more accurately estimate
S02 emissions, use the factor 1.25 S, where S ป weight (%) percent of sulfur
in the coke. See AP-42, Table 7.10-1.
^b This emission factor is an approximation. To more accurately estimate
S02 emissions, use the factor .292 S, where S = 'weight (%) percent of
sulfur in the fuel. See AP-42, Table 3.1-1.

dd use kiln code and appropriate 3-90 code for fuel used in kilns to properly
account for all SOX emissions.
ee These SCC codes are also applicable to Coal Cleaning Operations at power
plants.
ff This emission factor is from an earlier version of AP-42. See AP-42, Table
8.14-1.
99 Expressed as emission rate at point of release. For uncontrolled sources,
to account for emissions that settle out within the plant, code a ficti-
tious control device code for particulate of 006 (low efficiency gravit-
ational collector) with appropriate control efficiency. See AP-42,
Section 8.2.0 for table of typical control efficiencies for gravita-
tional settling.
hh several processes that routinely occur in Major Group 29 can be found under
other Major Groups. Specifically, note the following:
o waste or process gas and/or liquid fired boilers - SCC 1-02-***-**,
o internal combustion compressor engines - SCC 2-02-***-**.
o amine sweeting process - SCC 3-10-002-**.
o sulfur recovery process - SCC 3-01-032-**.
o sulfuric acid plant - SCC 3-01-022-** or 3-01-023-**.
11 Represents total CO and VOC generated. Report control device as 022 if CO
boiler is present to properly account for actual emissions.
Jj Units expressed as the equivalent number of valves, seals, flanges, or
drains in the refinery on an annual operating basis (8,760 hours/year).
For example, if there are 1,000 seals, all operating 8,760 hours/year,
then operating rate = 1,000. However, if the average operating time is
6,570 hours/year (3/4 of the total hours in a year), then operating rate
ป 1,000 x (6,570 8,760) = 750 seals. All counts of valves, seals,
flanges, and drains should be similarly adjusted to account for the
average annual hours of operation in the refinery.
kk Process changes may include such measures as raising the pH of the cooking
liquor, thereby lowering the free $03, relieving the pressure in the di-
gester before the contents are discharged, and pumping out the digester
contents instead of blowing them out.
TI The emission factor is non-stantard. The factor is derived from AP-42 by a
units conversion. See AP-42, Section 10.4.

PP For specific printing SCCs, see SCC 4-05-***-**.
QQ In-process fuel codes must always be used in conjunction with the appropri-
ate process code.
rr This emission factor is non-standard. The factor is derived from AP-42
and Bureau of Mines data. See AP-42, Section 8.6.
ss A table of typical solvent densities can be found in Section 3, Chapter 16
of AEROS Volume V.
tt These solvents are estimated to be of negligible photochemical reactivity.

ion on the identity and/ or quantity of make-up solvent used is not avail-
able.
vv These are general SCCs applicable to all industrial categories.
*w This emission factor is non-standard. The factor is derived from average
coating density data in AP-42, Section 4.2.2.
xx These solvents are used to thin coatings and thus should be used with one
of the coating codes.
yy This SCC should only be used to provide rough estimates of emissions for
cases when information on amount of fabric processed is not available.

Bulk plants are defined as facilities with daily throughputs of 20,000
gallons or less.
eee These solvents are often added by the user to the inks used in printing
processes. Thus, the solvent SCO's should not be used alone, but rather

SECTION 3. CROSSWALK STORAGE AND RETRIEVAL SYSTEM
Air toxic pollutant Tables 2-1 through 2-5 in this document ara con-
tained in an SIC/SCC/Po Llueanc Crosswalk SysLcra ildvelopej by J"A a Jo:;^*:,..-.- :;_..
Pollutant Programs Branch to allow for easy access and updating of the
information in the tables. This software system is an IBM PC based applica-
tion that presents a comprehensive listing of SIC and SCC codes and their
likely associated pollutants.
The niodules of the crosswalk program allow one to add or dei-icd, tclo.;,
or browse specific data, and to print out the tables. The system is written
in dBase III Plusฎ (Ashton Tate) and compiled using the Quicksilver Compiler'R:
(WordTech Systems). The system files are distributed on diskettes created
with the DOS BACKUP command.
This software system has been created specifically to allow easy data
manipulation even by fairly inexperienced users. Use of the system is
explained in a user's manual being released at the same time as this docu-
ment. 1 Also, EPA is making available the system and data base records on
three high-density diskettes to agency users. Users will need an IBM PC
compatible computer with 512 kilobytes of random access memory and a hard
disk with at least 4 megabytes of free storage. Requests for these materials
can be made by contacting the Noncriteria Pollutant Programs Branch, U.S. EPA,
OAQPS, MD-15, Research Triangle Park, North Carolina 27711, or by calling
(919) 541-5373 or (FTS) 629-5373.

16. ABSTRACT
This report presents an Air Toxic Pollutant Crosswalk that associates emitting
source categories with specific air toxics compounds. This is a qualitative associ-
ation and does not provide any information about the quantities of pollutants emitted
from the source categories. The crosswalk contains pollutant names, CAS numbers,
industrial source categories (SIC codes), and emitting source- classifications (SCC
codes). Appendices C-G of the EPA report, Compiling Air Toxics Emissions Inventory,
EPA-450/4-86-010, were updated and expanded to develop this report. In addition, a
software system containing the crosswalk was developed for easy access and updating
of the data. Use of the system is explained in the EPA report, Toxic Air Pollutant/
Source Crosswalk - Information Storage and Retrieval System User's Manual, EPA-450/
4-87-023b. EPA is making available the system and data base records to agency users
upon request.
The purpose of this report is to offer a technical service to air pollution con-
trol agencies in performing preliminary assessments of the types and sources of toxic
compounds present in an area. The crosswalk helps agencies to identify the potential
of pollutants to be emitted from sources in an area.
