Source Testing Request for Electric Arc Furnace Steelmaking Facilities:

Procedures, Methods, and Reporting Requirements

This document provides an overview of approved methods, target pollutant
units of measure, and reporting requirements for owners/operators of
electric arc furnace (EAF) steelmaking facilities who are required to
provide emission test data under EPA’s authority under the Clean Air
Act (CAA) section 114. (42 U.S.C 7417).  See Enclosure 3 for details
about this authority.  The purpose for this testing is to gather data on
air pollutant emissions from EAF steelmaking facilities in this source
category for EPA air pollution rules that apply to these sources.  This
document is organized as follows: 

	1.0   Stack Testing Procedures and Methods

	2.0   How to Report Data

	3.0   How to Submit Data

	4.0   Contact Information for Questions

1.0  Stack Testing Procedures and Methods

This information collection request includes stack (performance) test
data requests for mercury, particulate matter (PM), PM 2.5 micrometers
(µm) or less in diameter (PM2.5), and carbon monoxide (CO) along with
EPA Method 9 observations of melt shop opacity.  We understand that
emission testing for some of these pollutants may have been recently
completed for some or all of the facilities.  In that case, we are not
requesting additional emission testing but only the submittal of the
test reports representative of your current operations.  You may submit
previous test reports instead of testing if the tests were conducted
within the past 5 years (2005 or later) using EPA methods shown in Table
1 and meet the following criteria:

Mercury testing was performed for the EAF primary control device for at
least 30 days using EPA Performance Specification (PS) 12A, 12B, or EPA
Method 30B.  (Note that we would like reports of tests performed in the
last five years for mercury measured by ANY method for information
purposes only; see Enclosure 1.)

Mercury testing was performed for the EAF control device for fugitive
emissions from charging and tapping for at least 7 days using EPA
Performance Specification (PS) 12A, 12B, or EPA Method 30B.  (Note that
we would like reports of tests performed in the last five years for
mercury measured by ANY method for information purposes only; see
Enclosure 1.)

CO testing was performed using EPA Method 10 or 10B; or CO data was
collected from a CO continuous emissions monitoring system (CEMS).

PM and PM2.5 (both filterable and condensable) testing was performed for
the EAF primary control device or control device for fugitive emissions
from charging and tapping according to the testing procedures in the
NSPS (Subparts AA or AAa) or the GACT standard (Subpart YYYYY). 

Melt shop opacity readings were performed during the EAF PM and PM2.5
tests.

PM and PM2.5 (both filterable and condensable) testing was performed
according to your permit requirements for emission controls (other than
the EAF primary control device and control device for fugitive emissions
from charging and tapping) applied to AOD vessels or LMFs.

If you do not have previous tests that qualify, please perform testing
using the procedures described in Section 1.2 and Table 1.  Prior EPA
approval is required if you choose to submit past test data in order for
EPA to determine that the data and information you have identified are
representative.  

IMPORTANT NOTE:  If you intend to submit past test data, you must do so
by [insert date] because if EPA determines that such data are not
representative, you will need to conduct the testing and submit the test
data required by this survey by 120 days from the date of this letter.  

If you operate an EAF steelmaking facility, you are required to conduct
sampling to determine the following parameters:

Mercury (7439-97-6)

Carbon Monoxide (630-08-0)

Particulate Matter (Filterable)

Particulate Matter2.5 Filterable

Particulate Matter2.5 Condensable

Opacity

At a minimum, the process units listed below should be tested if you
operate an EAF steelmaking facility. 

Process Unit(s)	Test Location	Parameters to Test 

EAF primary control device 	Outlet 	Mercury, CO, PM, PM2.5 filterable,
PM2.5 condensable

EAF melt shop	Melt shop roof vent	Opacity

EAF control device for fugitive emissions from charging and tapping
Outlet	Mercury, PM, PM2.5 filterable, PM2.5 condensable

AOD control device	Outlet	PM, PM2.5 filterable, PM2.5 condensable

LMF control device	Outlet	PM, PM2.5 filterable, PM2.5 condensable

 

1.1  How to Select Sample Location and Gas Composition Analysis Methods

In addition to the tests for the target pollutants, use EPA Method 1 for
negative pressure baghouses and EPA Method 5D for positive pressure
baghouses, both in Appendix A of Part 60, to select the locations and
number of traverse points for sampling.  Please note that, for sources
equipped with emission controls, you are required to sample only at the
outlet of the control device.  For a complete copy of the methods and
guidance information, see   HYPERLINK
"http://www.epa.gov/ttn/emc/methods/method1.html" 
http://www.epa.gov/ttn/emc/methods/method1.html  and   HYPERLINK
"http://www.epa.gov/ttn/emc/methods/method5d.html" 
http://www.epa.gov/ttn/emc/methods/method5d.html .   

Analysis of flue gas composition, including oxygen concentration, also
must be performed simultaneous with PM, PM2.5, and CO testing using U.S.
EPA Methods 3A, 3B, or 3 of Appendix A of Part 60.  See   HYPERLINK
"http://www.epa.gov/ttn/emc/methods/method3a.html" 
http://www.epa.gov/ttn/emc/methods/method3a.html  for Method 3A,  
HYPERLINK "http://www.epa.gov/ttn/emc/methods/method3b.html"

information. 

1.2  Source Test Methods and Reporting

Table 1 presents a summary of the required and recommended alternative
test methods, minimum number of tests runs required, minimum test run
duration, and units of measure.  For copies of the recommended U.S. EPA
methods and additional information, please refer to EPA’s Emission
Measurement Center website:    HYPERLINK "http://www.epa.gov/ttn/emc/" 
http://www.epa.gov/ttn/emc/ .  For copies of the recommended Other Test
Methods (OTM), please refer to   HYPERLINK
"http://www.epa.gov/ttn/emc/prelim.html" 
http://www.epa.gov/ttn/emc/prelim.html .  If you would like to use a
method not on this list, please contact EPA for approval of an
alternative method.  If you have not performed emissions testing using
EPA methods or approved alternatives (shown in Table 1) in the past 5
years that meet the criteria provided in Section 1.0, you must conduct
emissions testing for mercury, PM, PM2.5, and CO at the exit of each EAF
shop’s primary control device; opacity of emissions from the melt shop
during the EAF PM and PM2.5 test; mercury, PM, and PM2.5 at the exit of
each EAF shop’s control device for fugitive emissions, and PM, and
PM2.5 for each AOD vessel control device and LMF control device (if they
are separately controlled and not routed to the EAF primary control
device).  If you have test data that were collected in the last five (5)
years, we also would like to have these data.  See Enclosure 1 for
details about the information we need in addition to these tests
reports.

Concentration and Flow Measurements—Positive Pressure Fabric Filters
(baghouses)

In the case of sampling at positive pressure baghouses for PM and PM2.5
concentrations, conduct sampling of the exhaust of one compartment of
the baghouse using the procedure for setting isokinetic sampling rates
as described in Method 5D.  In addition, the compartment selected should
be the one most representative of normal operation.  Only one baghouse
compartment needs to be traversed for PM, and for mercury, only a single
representative point in one compartment needs to be sampled.  Follow
Section 8.3 in Method 5D for determining the outlet stack flow rate
(i.e., measure the flow rate at the inlet using Method 2 and correct for
dilution air by measuring either temperature or CO2 concentration at
both the inlet and the sampling point, or alternatively, block or seal
all sources of dilution air between the flow measurement location and
the pollutant measurement location on a temporary basis during the
testing).

For the continuous mercury testing, facilities with positive pressure
baghouses may sample for mercury concentration at a single
representative point in a single compartment.  Determine the volumetric
flow rate during the continuous mercury emission testing using fan
performance curves for either static pressure or amperage unless the
facility already has calibrated flow meters installed for volumetric
flow rate, in which case the facility must use the calibrated flow
meters to determine the volumetric flow rate.  When using fan
performance curves, the facility should measure and record the static
pressure (or pressure differential across the fan) or the amperage,
collect at least three data points to confirm or adjust the
manufacturer's fan curve to the site-specific application, and monitor
that parameter to determine the volumetric flow rate during the mercury
emission test.  Alternatively, if the fan amperage is maintained during
the mercury testing within ± 15% of the average established during the
PM/PM2.5 testing, use the average flow rate from the PM/PM2.5 testing. 
Record fan amperage in accordance with the procedures in the NSPS
(Subpart AAa).  Facilities may also choose to install, calibrate, and
maintain a flow meter for continuously measuring and recording the
exhaust volumetric flow rate during mercury testing.  The volumetric
flow rate must be reported for each sampling period (e.g., daily to
weekly when using the sorbent trap).  

Continuous Flow Measurements—Negative Pressure Fabric Filters
(baghouses)

For the continuous mercury testing, facilities with negative pressure
baghouses should determine the volumetric flow rate using fan
performance curves as described above for positive pressure baghouses
unless the facility already has calibrated flow meters installed for
volumetric flow rate, in which case the facility must use the calibrated
flow meters to determine the volumetric flow rate.  A facility may
choose to install, calibrate, and maintain an instrument for
continuously measuring and recording the exhaust flow rate to the
atmosphere rather than using fan performance curves.  If this option is
chosen, install each sensor of the flow rate monitoring system in a
location that provides representative measurement of the exhaust gas
flow rate at the sampling location for mercury concentration taking into
account the manufacturer’s recommendations.  The flow rate monitoring
system must be:

Designed to measure the exhaust flow rate over a range that extends from
a value of at least 20 percent less than the lowest expected exhaust
flow rate to a value of at least 20 percent greater than the highest
expected exhaust flow rate.

Accurate within 5 percent of the exhaust flow rate.

Equipped with a data acquisition and recording system that is capable of
recording values over the entire range specified above. 

The signal conditioner, wiring, power supply, and data acquisition and
recording system for the flow rate monitoring system must be compatible
with the output signal of the flow rate sensors used in the monitoring
system.  The flow rate monitoring system must be designed to complete a
minimum of one cycle of operation for each successive 15-minute period. 
To have a valid hour of data, the flow rate monitoring system must
measure and record at least three of four equally spaced data values (or
at least 75 percent of the total number of values) for each hour (not
including startup, shutdown, malfunction, or out-of control periods). 
Perform an initial calibration of the flow rate monitoring system
according to manufacturer’s recommendations.  

Testing Similar EAFs 

If a facility has multiple EAFs that melt the same types of scrap from
the same scrap suppliers and there are no significant differences in the
other materials charged to the furnace or in the type of steel produced,
the facility is required to test only one of these EAFs for mercury
emissions under this test request.  Please fill out the table in
Appendix C to report the parameters used to establish similarity. 
Please provide a description of the required parameters used to
establish the similarity between your EAFs, along with other identifying
information.  All parameters that are denoted with an asterisk (*) are
required to be the same for EAFs to be considered “similar.”

Procedures for EAFs Operating on Reduced Schedules

We understand that some EAFs may not operate during each shift every day
or may not operate every day.  For EAFs that do not operate for full
days or every day during the week, sampling for mercury emissions from
the primary control device must be performed for each day the EAF
operates, even if it operates for only part of the day, for 30
consecutive calendar days when using PS 12A or Method 30B, or for four
(4) consecutive calendar weeks when using PS 12B.  If the sampling term
described above does not provide at least 8 daily average measurements,
the EAF facility must continue sampling and obtain a minimum of 8 daily
average mercury measurements for the primary control device.  

Sampling for mercury emissions for the control device for fugitive
emissions from melting and tapping (if different from the primary
control device) for an EAF not on a full operating schedule must be
performed for seven (7) consecutive calendar days when using PS12A or
Method 30B, or for one (1) calendar week when using PS 12B.   If the
sampling term described above does not provide at least three (3) daily
measurements for the fugitive emission control device, the EAF facility
must continue sampling and obtain a minimum of three (3) daily average
mercury measurements for the fugitive emission control device.  

If your EAF does not operate every day and you qualify for the minimum
sampling requirements above, please submit documentation (such as copies
of heat sheets showing operating days and hours) that shows this reduced
operating schedule has been in place for at least three (3) months from
the date of this letter.

a If a single emission control device serves multiple emission units
(e.g., any combination of EAF exhaust, EAF fugitive emissions, AOD
vessel, and LMF), measure and report the combined emissions and test
while each unit is operating under normal and typical operating
conditions

b Where mg/m3 = milligrams per dry standard cubic meter, mg/hr =
milligrams per hour, mg/ton = milligrams per ton, acfm = actual cubic
feet per minute, and dscfm = dry standard cubic feet per minute.  Data
may be obtained and/or recorded in alternative units of measure, but
they must be converted to the above units before reporting for this test
request. 

c See the text above for minimum sampling requirements for EAFs that do
not operate all day or do not operate every day in the “Procedures for
EAFs Operating on Reduced Schedules” section.

d Heat cycle sampling may start and stop at any point in the cycle as
long as the start and stop occur at the same point in the cycle.  An
“integral number” means a whole number, e.g., 1, 2, 3, and not half
or partial numbers, e.g., 1.5, 2.75, etc.  Sampling for an integral
number of heat cycles is not required for facilities operating two or
more EAFs controlled by a common control device; in this case, follow
the testing requirements in the NSPS (Subpart AAa).  

e You may measure CO2 concentrations at both the inlet and outlet of the
positive pressure fabric filter in conjunction with the pollutant
sampling to correct pollutant concentrations for dilution and to
determine isokinetic sampling rates. You may use either Method 3A or 3B
(with integrated bag sampling).  Alternatively, all sources of dilution
air between the flow measurement location and the pollutant measurement
location can be blocked or sealed on a temporary basis during the
testing. 								(Continued)

f Establish a fan amperage range or correlation with flow during
PM/PM2.5 testing.  Determine flow rate using the correlation with fan
amperage, or if the fan amperage is maintained during the mercury
testing within ± 15% of the average established during the PM/PM2.5
testing, use the average flow rate from the PM/PM2.5 testing.  Record
fan amperage in accordance with the procedures in the NSPS (Subpart
AAa).

g Facilities must use a continuous flow meter if already installed, or
may elect to install and use a flow meter if they choose to (See Section
1.2 for details).  

1.3  Electric Arc Furnace Baghouse Dust Sampling and Mercury Analysis

If you operate an electric arc furnace steelmaking facility, you must
sample and analyze the EAF baghouse dust during the mercury emission
test to determine the concentration of mercury.  EAF baghouse dust
samples must be collected once per day during each week of the test for
mercury emissions and composite into a weekly sample.  Each weekly
sample must be analyzed using the procedures in the following table

Parameter/Pollutant	Recommended Method	Alternative Method	Units of
Measure

EAF Dust Digestion	EPA SW 846 Method 3050	EPA SW 846 Method 3051	Not
applicable

For copies of the recommended U.S. EPA SW-846 methods, please refer to
EPA’s SW-846 Online website:    HYPERLINK

http://www.epa.gov/waste/hazard/testmethods/sw846/index.htm .

1.4  Ensuring Data Quality of the Source Tests Performed

While we are not specifying numerical minimum detection levels for the
tests to be performed, we have specified the testing conditions and
methods required, including test run times when appropriate, which we
believe will provide data of a quality sufficient for decision making.  

We remind source owners and testers of the CAA section 114(a)(1)
requirement to provide information requested for the development of
emissions standards using methods that provide data necessary for the
decisions.  That includes data of quality sufficient to support those
decisions.  For the most part, we can identify test methods and
procedures that will satisfy those decision making needs (e.g., minimum
sampling times).  In other cases, we recognize that the source owner's
or tester's selection of test procedures or equipment could bear
significantly on the quality of the data. 

We believe that the CAA is clear in that it is the responsibility of the
source and the tester to apply methods and procedures that result in
optimized data quality, including providing for the lowest possible
detection limits considering practical and reasonable limitations.  For
example, source owners and testers should not automatically choose to
use low or medium quality equipment for testing (e.g., for cost reasons)
if high quality equipment is reasonably available.  We will review test
reports in light of this expectation and will be particularly mindful of
whether the testing procedures applied are representative of the highest
reasonably expected capabilities (e.g., comparing reported minimum
measurement detection levels between tests and testers).  

If we believe that a source owner or tester has failed to meet the
requirement of the CAA to provide data sufficient for our decisions, we
can and will request additional measurements that require the use of
improved testing procedures. 

On completion of your required tests, please provide either the full
test reports or summary pages that contain the information listed below.
 If only test summaries are submitted, please ensure that the following
information is included (at a minimum):  

Run-by-run pollutants and emission rates measured (e.g., lb/hr, gr/dscf,
lb/ton) for the pollutants of interest for this survey, including
mercury, CO, and any of the forms of PM plus melt shop opacity
observations; 

Stack parameters (volumetric flow rates, temperature, % oxygen, %
moisture, etc.); 

Names of the test methods or procedures used; 

For PM, identify whether it is filterable (front half) PM, total PM
(filterable plus condensable), PM10, or PM2.5 (indicating whether it is
filterable, condensable, or both);

Information on actual production or processing rates during the test; 

Identify any runs where the process or control device was not operating
normally and any runs that were invalidated (including the reason); and

Quality assurance and quality control activities performed.  

In addition to the emission test data, you should also report the
following process information recorded at the time of, and during, the
emissions test:  

Stack or exhaust gas flow rate (as determined using EPA Method 2, 2F, 
2G, or 5D); and

Production rate of raw steel during each of the emission tests, as in
Table 2 below.

2.0  How to Report Data

The method for reporting the results of any testing and monitoring
requests depends on the type of tests and the type of methods used to
complete the test requirements.  This section discusses the requirements
for reporting the data.

2.1  Reporting Stack Test Data

If you conducted additional stack tests in response to this test request
using one of the methods listed in Table 3 shown below, you must report
your data using the EPA Electronic Reporting Tool (ERT) Version 3.  ERT
is a Microsoft® Access database application.  Two versions of the ERT
application are available.  If you are not a registered owner of
Microsoft® Access, you can install the runtime version of the ERT
Application.  Both versions of the ERT are available at   HYPERLINK
"http://www.epa.gov/ttn/chief/ert/ert_tool.html" 
http://www.epa.gov/ttn/chief/ert/ert_tool.html .  The ERT supports an
Excel spreadsheet application (which is included in the files downloaded
with the ERT) to document the collection of the field sampling data. 
After completing the ERT, you will also need to attach an electronic
copy of the emission test report (PDF format preferred) to the
Attachments module of the ERT.  Both the ERT spreadsheet and the
emission test report should be transmitted to EPA using one of the
options described below in Section 3.  You are not required to report
your data from previously-conducted emission tests using the ERT. 

Alternatively, if you perform tests with methods PS12A, PS12B, or EPA
Method 30B for mercury; EPA Method 9 for opacity; EPA Method 10B or CO
CEMS for CO testing; EPA Method 2F, 2G, or 5D for flow rate; EPA Method
3B for O2/CO2; or any of the EPA SW 846 Methods for EAF baghouse dust
sampling and analysis, you must report the results of these tests in an
individual Microsoft® Excel “EAF Emission Test Template.”  The
individual Excel EAF templates are specific to each pollutant and type
of unit, and they can be downloaded from the Electric Arc Furnace EPA
Test Request 2010 website   HYPERLINK "http://icr2010.rti.org" 
http://icr2010.rti.org .  

You must report the results of each test on an appropriately labeled
worksheet that you develop using the EAF Emission Test Template that
corresponds to the specific tests requested at your facility.  If more
than one source at your facility was tested using methods not currently
supported by the ERT, you must make an electronic copy of the EAF
worksheet to report these data, making sure to update the source ID in
order to distinguish between each separate source/test.  After
completing the EAF worksheet, you must also submit an electronic copy of
the emission test report (PDF format preferred).  Both the EAF worksheet
and the emission test report should be transmitted to EPA using one of
the options described below in Section 3.

2.2  Required Fields for ERT Reporting

Enclosure 8 provides an EPA ERT Version 3 example test plan and lists
each field within the ERT.  Note that the required reporting includes
the latitude and longitude of each stack tested (in decimal degrees to 6
decimal places).

2.3  Guidance for Calculating and Reporting Measurements Less Than
In-Stack Method Detection Levels for Emissions Data Submitted in
Response to Information Collection Request (ICR) Programs 

Please identify the status of the measured values relative to the
detection levels on the individual Excel spreadsheet or in the ERT
Access database using the following descriptions:

BDL (below detection level) – all analytical values used to calculate
and report an in-stack emissions value are less than the laboratory’s
reported detection level(s); 

DLL (detection level limited) – at least one but not all values used
to calculate and report an in-stack emissions value are less than the
laboratory’s reported detection level(s); or

ADL (above detection level) – all analytical values used to calculate
and report an in-stack emissions value are greater than the
laboratory’s reported detection level(s).

For each reported emissions value, insert the appropriate flag (BDL,
DLL, or ADL) in the Note line of Excel emission test spreadsheet
template or in the Flag column of the Electronic Reporting Tool (ERT).

When reporting and calculating individual test run data:

For analytical data reported from the lab as “nondetect” or “below
detection level;”

Include a brief description of the procedures used to determine the
analytical detection and in-stack detection levels:

In the Note line of Excel emission test spreadsheet template; or

In the Comments line of Lab Data tab in the Run Data Details in the ERT.

Describe these procedures completely in a separate attachment including
the measurements made, the standards used, and the statistical
procedures applied.

Calculate in-stack emissions rate for any analytical measurement below
detection level using the relevant detection level as the “reported”
value.

Report the calculated emissions concentration or rate result:

As a bracketed “less than” detection level value (e.g., [<0.0105])
in the Excel emission test spreadsheet template and include the
appropriate flag in the Note line; or

As a numerical value in the ERT with the appropriate general flag in the
Flag column and as a bracketed “less than” detection level value
(e.g., [<0.0105]) followed by a space and any specific flag identifier
in the Comments line.  The following specific flag identifiers are
commonly used by laboratories:  B, E, J, Int, R, DPE.

Report as numerical values (i.e., no brackets or < symbol) any
analytical data measured above the detection level including any data
between the analytical detection level and a laboratory-specific
reporting or quantification level (i.e., flag as ADL).

For pollutant measurements composed of multiple components or fractions
(e.g., Hg and other metals sampling trains) when the result for the
value for any component is measured below the analytical detection
level; 

Calculate in-stack emissions rate or concentrations as outlined above
for each component or fraction;

Sum the measured and detection level values as outlined above using the
in-stack emissions rate or concentrations for all of the components or
fractions; and

Report the sum of all components or fractions:

As a bracketed “less than” detection level value (e.g., [<0.0105])
in the Excel emission test spreadsheet template and include the
appropriate flag in the Note line; or

As a numerical value in the ERT with the appropriate flag in the
Comments line.

Report also the individual component or fraction values for each run if
the Excel emission test spreadsheet template or ERT format allows; if
not (i.e., the format allows reporting only a single sum value):

For the Excel emission test spreadsheet template, next to the sum
reported as above report in the Notes line the appropriate flag along
with the values for the measured or detection level value for each
component or fraction as used in the calculations (e.g., 0.036,
[<0.069], 1.239, [<0.945] for a four fraction sample)

For the ERT, next to the sum reported as above, report in the Flag
column the appropriate general flag in the Comments column and the
measured or detection level value for each component or fraction as used
in the calculations followed by a space and any specific flag identifier
provided by the laboratory (e.g., 0.036, [<0.069] J, 1.239, [<0.945] B
for a four fraction sample)

For measurements conducted using instrumental test methods (e.g.,
Methods 3A,  10)

Record gaseous concentration values as measured including negative
values and flag as ADL; do not report as BDL

Calculate and report in-stack emissions rates using these measured
values

Include relevant information relative to calibration gas values or other
technical qualifiers for measured values in Comments line in the ERT

When reporting and calculating average emissions rate or concentration
for a test when some results are reported as BDL

Sum all of the test run values including those indicated as BDL or DLL
as numerical values

Calculate the average emissions rate or concentration (e.g., divide the
sum by 3 for a three-run test)

Report the average emissions rate or concentration average:

As a bracketed “less than” detection level value (e.g., [<20.06]) in
the Excel emission test spreadsheet template and include the appropriate
flag in the Note line

As a numerical value in the ERT and include the appropriate flag in the
Comments line.

NOTE: For all listings above which contain the word "compounds" and for
glycol ethers, the following applies: Unless otherwise specified, these
listings are defined as including any unique chemical substance that
contains the named chemical (i.e., antimony, arsenic, etc.) as part of
that chemical's infrastructure.

1:  X'CN where X = H' or any other group where a formal dissociation may
occur. For example KCN or Ca(CN)2

2:  Includes mono- and di- ethers of ethylene glycol, diethylene glycol,
and triethylene glycol R-(OCH2CH2)n -OR' where

n = 1, 2, or 3

R = alkyl or aryl groups

R' = R, H, or groups which, when removed, yield glycol ethers with the
structure: R-(OCH2CH)n-OH. Polymers are excluded from the glycol
category.  Also excludes ethylene glycol monobutyl ether (EGBE)
(2-Butoxyethanol) (Chemical Abstract Service (CAS) No. 111-76-2)  and
surfactant alcohol ethoxylates and their derivatives (SAED).

 3:  Includes mineral fiber emissions from facilities manufacturing or
processing glass, rock, or slag fibers (or other mineral derived fibers)
of average diameter 1 micrometer or less.

4:  Includes organic compounds with more than one benzene ring, and
which have a boiling point greater than or equal to 100º C. 

5:  A type of atom which spontaneously undergoes radioactive decay.
