Project Summary
Stationary Source Sampling and
Analysis Directory (SSSADIR)
Version 2.1
Merrill D. Jackson and Larry D. Johnson
The U.S. Environmental Protection
Agency (EPA), in developing and evalu-
ating sampling and analysis methodol-
ogy for stationary sources, has com-
piled information on availability and ap-
plicability of sampling and analytical
methods. Information has also been
summarized on the applicability of the
gas chromatography/mass spectrom-
etry as the analytical method. This in-
formation is accessible in this docu-
ment. The Stationary Source Sampling
and Analysis Directory (SSSADIR) has
information on which sampling and ana-
lytical methods to use for organic com-
pounds listed in Title III of the Clean
Air Act Amendments (CAAA) of 1990,1
as well as Appendices VIM2 and IX3 of
RCRA compounds, and the status of
method evaluation for these analytes.
The SSSADIR provides information on
CAAA compounds for which EPA has
no potential methods available but sug-
gests ways to develop methods.
This Project Summary was developed
by EPA's National Exposure Research
Laboratory (NERL), Research Triangle
Park, NC, to announce key findings of
the research project that is fully docu-
mented in a separate report of the same
title (see Project Report ordering infor-
mation at back).
Introduction
The Methods Branch, NERL, while
evaluating stationary source sampling and
analytical methodology for use in conjunc-
tion with the hazardous waste incineration
regulations Appendices VIII2 and IX,3
RCRA and the CAAA, Title III, 1990,1 has
assembled information on all the listed
compounds. Some compounds have vali-
dated methods available, some have meth-
ods that might work, and others have no
method available at this time. This infor-
mation has been gathered into this EPA
report.
Most databases of sampling and ana-
lytical methods are analyte-based. If a
method has a specific list of analytes ap-
plicable to that method, the database can
readily locate all methods applicable for
that analyte. However, many sampling and
analytical methods for stationary sources
do not incorporate a specific list of appli-
cable analytes. These methods (such as
Method 0030)4 include only some gen-
eral guidance (e.g., a boiling point range)
on the analytes amenable to the method.
In an analyte-based database, it is impos-
sible to find out that Method 00304 is the
method of choice for sampling and analy-
sis of carbon tetrachloride in stationary
sources. The SSSADIR, a database stand-
alone program that can be run on any
personal computer, provides a solution to
the problem of locating appropriate sta-
tionary source sampling and analytical
methods for specific analytes. This ver-
sion of SSSADIR replaces the "POHCs
Directory, Version 1".5 The original POHCs
Directory contained only the compounds
listed in Appendix VIII.2 The SSSADIR
has retained all these compounds, edited
and upgraded to incorporate recent infor-
mation, and has added all the compounds
from Appendix IX3 and the compounds
listed in Title III Amendments to the Clean
Air Act of 1990.1 The present directory
contains information on properties (e.g.,
boiling point, melting point, flammability)
for each individual compound listed. If a
validated method is available for the com-
pound, this validated method is listed with
the pertinent reference. However, if no
method validation information is available,
-------
either a proposed method is listed or the
method is left blank, indicating no current
known method. Problems with the sam-
pling or analytical methodology are listed
with suggestions for solutions, if known.
Physical properties are provided to permit
comparison of one compound to another
compound of known properties (such as
incinerability). The database may be
searched by several parameters such as
name, CAS number, boiling point,
incinerability index, and problems in sam-
pling or analysis.
The database provides a snapshot of
available information at one point in time.
Since method evaluation and method de-
velopment is an ongoing effort with the
EPA, new information is constantly be-
coming available. Future updates to the
database will focus on making information
on method evaluation available to provide
guidance on selection of methods. No
matter what information is available to sug-
gest that a given compound "should work"
using a specified sampling and analytical
methodology, the ultimate test is always
provided by an actual field evaluation of
that methodology and compound at a sta-
tionary source. Even a successful method
evaluation at a particular stationary source
does not guarantee universal success for
the methodology and analyte at any, or
every, stationary source. However, the
guidance available through SSSADIR can
provide a starting point for determining
applicable methodology.
