&ERA Project Summary
Modified Method 5 Train and
Source Assessment Sampling
System Operator's Manual
Lynn M. Schlickenneder, Jeffrey W. Adams, and Kathleen E Thrun
Two stack sampling trains, the Mod-
ified Method 5 (MM5) train and the
Source Assessment Sampling System
(SASS) train have been identified as the
sampling devices to be used in assessing
the Destruction and Removal Efficiency
(DRE) of Principal Organic Hazardous
Compounds (POHCs) by hazardous
waste incinerators. Recognizing the
need to establish sampling protocols,
this document has been prepared to
provide a detailed guide for the use of
each of these devices in sampling stack
gas effluents from these facilities. Step-
by-step procedures for the cleaning,
assembly, calibration, use of, and re-
covery of samples from each device are
detailed. Guidelines for the reduction
and presentation of data are included.
This Project Summary was developed
by EPA's Air and Energy Engineering
Research Laboratory. 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
In support of the EPA's Hazardous
Waste Incineration Program, EPA's Office
of Solid Waste (OSW) and the Air and
Energy Engineering Research Laboratory
(AEERL) recognize the need for sampling
and analytical procedures to assess the
Destruction and Removal Efficiency (DRE)
of the Principal Organic Hazardous Com-
pounds (POHCs) by hazardous waste
incineration facilities. The determination
of the DRE requires the measurement of
POHC concentrations in gaseous efflu-
ents from incinerator stacks. Two stack
sampling trains, the Modified Method 5
(MM5) train and the Source Assessment
Sampling System (SASS) train, have
been identified for the sampling of organic
material in incinerator stack gas effluents.
This document is a detailed user's guide
for operating each of these sampling
devices.
Development of the Manual
The user's guide is a start-to-finish
handbook for the cleaning, assembly,
calibration, use of, and recovery of sam-
ples from each sampling device. The
sampling preparation instructions in-
clude: calculations needed to determine
the minimum sample volume to be col-
lected for the MM5 train, and calculations
needed to determine the optimum nozzle
size and required orifice pressure drop for
sampling at near-isokinetic conditions
with the SASS train.
The sampling methodology descriptions
include sample recovery flow diagrams
and example coding schemes to which
the user can refer during field operations.
Additional information (e.g., blank data
forms for each train, the sorbent resin
pre-extraction procedure, and specialized
SASS train cleaning procedures) appear
in the Appendices.
The manual does not provide recom-
mendations or suggestions for analysis
protocols, which are developed for each
individual program based on procedures
specified in other manuals.
The Finished Manual
This manual is divided into three parts
The first is an overview and comparison
of the sampling trains. Design parameters
-------
are described to assist test program
personnel in deciding which sampling
system is better suited for their program.
The second and third parts outline the
step-by-step procedures for using the
MM5 and SASS trains, respectively.
Conclusions
The sampling procedures and data
reduction guidelines needed to determine
POHC concentrations in incinerator stack
gas effluents are presented in a single
document. The data obtained using this
handbook will be applicable to the deter-
mination of the DREs from hazardous
waste incineration facilities.
