GUIDELINES FOR THE
OBSERVATION OF CONTINUOUS EMISSION MONITOR
PERFORMANCE SPECIFICATION TESTS
1.0 Introduction
Vhen stationary source owners or operators conduct Performance
Specification Tests (PSTs) of installed continuous emission monitors (CEMs) as
required by New Source Performance Standards ( NSPS), State Implementation Plans
(SIP), or other local regulations, the agency appoints a representative to
observe the tests. This manual is intended to provide guidelines for the
representative's role and general responsibilities as an observer. Detailed
explanations of the PST and specific instructions and recommendations for the
test report reviewer appear in a separate manual entitled, "Monitor Performance
Tests for Pollutant and .Diluent Gas Monitors: Reporting Requirements, Report
Format, and Review Procedures." The observer is referred to this manual and to
the appropriate Federal and State regulations for detailed technical information
concerning the tests.
The source owner or operator is responsible for planning and conducting the
PST. In most cases, a consultant is hired by the owner or operator to perform
the test. Typically, this consultant is designated as an authorized
representative of the source and, throughout this document, is referred to as
"tester" and "test consultant."
The functions of the agency observer are to represent the interests of the
agency during the planning and performance of the PST, and to provide
appropriate documentation of the PST for the test report reviewer. The observer
must ensure that the PST is performed according to the procedures delineated in
-------
the Performance Specifications (40 CFR 60, Appendix B) . In doing so, the
observer must work cooperatively with the source and with the test consultant.
He must be specific and forthright in his requests, while being respectful of
the positions of the other parties involved. Antagonistic or adversary
approaches will usually defeat themselves in these situations. Cooperation is
in the best interest of all parties, and will result in maximum success.
The activities of the agency observer may be divided into three phases:
pretest activities, onsite observation, and preparation of the observer's
report. These activities are discussed in the following sections.
It is strongly recommended that all of the observer's activities be
conducted by the same individual; when more than one person are involved, all
persons representing the agency must work closely together to ensure an
effective agency role in the PST.
The appendix of this document contains a detailed checklist for the PST
observer. Separate checklists for preliminary communications, pretest meetings,
and onsite observation are included. The observer should review these
checklists and use them appropriately to document all phases of the test
sequence .
-------
2. 0 Pretest Activities
The source owner or operator is required to notify the agency of his
intention to conduct the PST. (NSPS sources are required to give 30 days
notice; requirements for SIP sources may vary.) The notice indicates chat
arrangements for the test are underway and that the source is prepared to
schedule the test. Once source notification has been received, an agency
representative should be designated to observe the test.
Initially, the observer should establish contact with the source owner or
operator and inform him that he plans to observe the test. Ihe source is then
responsible for notifying the observer of all PST activities (i.e., test
schedule, pretest meeting, etc.). This initial agency-source contact
establishes the lines of communication among all parties from the outset of the
test sequence. At this time, the observer should query the source owner or
operator for information pertaining to the source (e.g., identification and
location, plant and monitor design and operating parameters, pollutants to be
measured, sampling locations, data from previous PST, etc.), and pertaining to
the tester (e.g., identification and location, sampling equipment and laboratory
information, test methods to be used, etc.).
After the source is contacted, the observer should familiarize himself with
the operating principles of the installed CEM, the source process and
anticipated operating conditions, and the requisite test methodology. The
observer should also review available information from control agency records of
the monitor (and/or relevant source emission tests). He should discuss
procedural details not specified in the Reference Methods and Performance
Specifications with the source and the tester, and achieve an
agency-source-tester concurrence prior to initiation of the test.
-------
The observer should attend any pretest meeting held by the source. Although
there is no requirement for pretest meetings, these meetings and other informal
gatherings of source, testing, and agency personnel provide opportunities for
clarification and negotiation of issues, and for the dissemination of
information about the test protocol and its possible problems. Typically,
pretest meetings are scheduled for the convenience of the source and the tester;
however, most sources are quite willing to accotnodate the observer's schedule
provided that they know in advance that he plans to attend and if a schedule
satisfactory for all three parties can be arranged .
The source and/or the tester must formulate a test protocol and submit it
to the observer for review and approval before the initiation of the PST. The
observer must make clear any special requests he has for the tester or the
source at this time. He should also review and approve (or disapprove) any
modifications to the standard procedures or other procedures not prescribed in
the Performance Specifications proposed by the tester. The observer should
include all draft versions and the finalized protocol in his report.
The observer must know the limits of his authority. Undoubtedly, the test
observer will be called upon to determine the acceptability of test procedures,
sampling methodology, etc. If the observer does not have authority for such
decisions, he must be able to contact an agency representative who has such
authority. Failure to establish this line of authority in advance will hinder
the satisfactory completion of the test program, which is the goal of the
source, the tester, and the agency.
The test schedule should be finalized during the pretest negotiations.
However, this test schedule is dependent upon many variable factors: boiler
operation, monitor operation, process conditions, etc. Testing cannot begin
-------
until satisfactory conditions are achieved simultaneously for all of these
variables, and despite the most careful planning, delays in the test schedule
are common. The tester and the observer must therefore be ready when appropriate
conditions are achieved. Once the PST has commenced, test problems may ' r.jse
additional delays. To complete the tests, the tester may continue his work well
into the evening and for most of the night, provided that proper lighting is
available. The observer should consult with the tester during the pretest
negotiations as to his firm's policy regarding the length of the test day.
Thus, the observer must be flexible and accommodate the tester's schedule.
If additional testing, modified sampling procedures, or additional quality
assurance procedures, etc. are necessary to accommodate particular regulatory
provisions, monitor-specific problems, and/or unusual source-specific
circumstances, the observer must inform the source and tester of any such
deviations from standard procedure as early as possible. Failure to do so may
compromise the test results and create problems.
Before the PST, the observer should review the "Onsite Observation" portion
of the observer's checklist contained in the appendix of this document. The
checklist is designed to apply to all types of continuous monitor PSTs . For the
checklist to be useful, the observer must be familiar with the portions of it
that apply to his particular situation, and he should note in advance those
portions of the checklist that must be completed.
The checklist is intended to facilitate the job of the observer; it is not
a complete, self-contained report in itself. Although its length may seem
cumbersome, it provides a format for the recording of information the observer
may wish to use. Tne observer himself, however, must finally decide vhich
information is important and which is not.
-------
In conclusion, responsibilities and activities of the agency and the
observer during the pretest period may be summarized as follows:
1. The agency should designate an observer upon receiving notice from the
so ur ce.
2. The observer should contact the source and obtain pertinent
information.
3. The observer should review all available pertinent information, both on
the source and on the PST methodology.
4. The observer, as agency representative, should clarify his authority to
the source and tester. If the necessary authority resides outside the
observer, contingency plans should be made for contacting the agency
representative who is authorized to make decisions.
5. The observer should attend the pretest meeting, if possible.
6. Before the initiation of the PST, the observer should review the test
protocol, negotiate necessary changes, and approve it.
7. The observer should obtain the test schedule and make appropriate plans
to attend.
8. The observer should review the observer's checklist and utilize it for
the onsite observation.
-------
3.0 Onsite Observation
The observation of the PST is perhaps the most important of the observer's
responsibilities following the establishment of the test protocol. The
observer must perform all preparatory activities to maximize the effectiveness
of his observation. He must complete the gathering of preliminary information
prior to the initiation of testing so that he can give his full attention to
the performance of the test.
The observer should arrive onsite on time for any pretest activities and
should attend any informal meetings with the tester and the source immediately
before the test to settle last minute details. He may be asked to observe and
approve non-standard procedures to be employed during the test. Consequently,
the observer should allow ample time for these activities and for any other
pretest inspections he may wish to perform, the observer should obtain and
examine: (1) the results of any tests for which the monitor manufacturer is
allowed to certify conformance with the applicable specifications (i.e., design
specification tests for transmissometers, some calibration error checks for
some gas monitors), (2) the results of calibration gas analysis and/or
manufacturer's certification of calibration gas cell values, and (3) the
required pretest calibration results for the tester's sampling equipment.
Once testing commences, the observer should watch all aspects of the test,
including test procedures, monitor operation, and source operating conditions.
It is unnecessary and time consuming for the observer to make his own separate
records of the data; he can observe the tester's record and initial the data
sheets to ensure that the data recorded are the data reported. The observer
must make judicious use of the checklist to note his observations; however,
time spent completing the checklist is time not spent observing. Therefore,
-------
the observer is advised to review the checklist in advance of the test and to
mark the appropriate information to be completed; if this is not done, the
observer could spend the majority of the test period working on the checklist.
The observer should be considerate of the tester during the PST; the
tester's attention will be focused on getting the job done, and during some
phases of the testing, distractions could jeopardize his work. When the
observer has questions for the tester, he should wait until an appropriate time
to ask them, unless it is imperative that the questions be resolved before
testing proceeds. Also, the observer should be respectful of the source's and
tester's equipment. Most sampling equipment is quite expensive, and much of it
is easily damaged . In general, a "hands-off" posture is the safest approach.
Regardless of the care taken to resolve all procedural questions in
advance, unforeseen situations are encountered frequently during the actual
test period. In such instances, the observer must approve or disapprove a
source's or tester's proposed solution on the spot. If he does not have the
authority to make such decisions, he should contact an agency representative
having the necessary authority. Any delays at this critical stage will result
in wasting valuable time and money.
At the conclusion of the test, the observer may wish to inspect the
tester's data sheets and initial them. Such a request should be made in the
spirit of cooperation. Indeed, the tester may wish to receive feedback from
the observer, and often such an interchange can prove mutually beneficial. The
observer should remember that his ultimate goal is to obtain reliable PST data
for the agency, and he should be willing to share his subjective and objective
observations and information.
-------
In conclusion, the observer's activities during the test may be summarized
as follows :
1. The observer should arrive onsite well in advance of the
scheduled beginning of the test to make final preparations for
accurate observation of both source and tester operations.
2. The observer should review data and/or test results from any
manufacturer's certification of conformance with specifications
and of any calibration gas analysis.
3. The observer should devote his primary energies to a careful
observation of the test procedures.
ij. The observer should be considerate of the source and the tester
and work with them to achieve the desired results.
5. The observer should be prepared to rule on problems that may
arise during the course of the test.
6. The observer should confer with the tester at the conclusion of
the test to exchange appropriate information and to discuss the
data quality and possible deficiencies.
-------
4.0 Observer's Report
At the conclusion of the test program, the observer must prepare a report
containing all pertinent information from his observation activities. The
observer's report aids the test report reviewer. Although the soundest and
most expedient practice is for the test observer to review the report, this is
not always feasible. Therefore, the observer should prepare a complete report
that can serve as an independent documentation of the test.
The outline below suggests an organization for an observer's report.
While the observer will finally determine the most appropriate report format,
the report must document thoroughly the activities of the observer, the source,
and the tester to be useful to the reviewer. Although recording the test
details is tedious, it is necessary to enable the reviewer to evaluate the test
report accurately. The observer must make notations of problems encountered,
and also state the acceptability of procedures. The observer should be specific
and concise, regardless of the report format chosen.

16. ABSTRACT
When stationary source owners or operators plan to conduct Performance Specifi-
cation Tests of installed continuous emission monitors, they are required to
notify the applicable control agency. The agency should then appoint a represen-
tative to observe the tests.
This document contains general guidelines for the agency observer on the performance
of pretest negotiations, on-site observations, and the preparation of his report.
Also, an observer's checklist for these activities is included.
