9 Va. Admin. Code § 5-50-30 - Performance testing
A.
Performance tests for new or modified sources shall be conducted and reported
and data shall be reduced as set forth in this chapter and the test methods and
procedures contained in each applicable subpart listed in
9VAC5-50-410 unless the board (i)
specifies or approves, in specific cases, the use of a reference method with
minor changes in methodology; (ii) approves the use of an equivalent method;
(iii) approves the use of an alternative method the results of which the board
has determined to be adequate for indicating whether a specific source is in
compliance; (iv) waives the requirement for performance tests because the owner
of a source has demonstrated by other means to the board's satisfaction that
the affected facility is in compliance with the standard; or (v) approves
shorter sampling times and smaller sample volumes when necessitated by process
variables or other factors. Any new or modified source, for which no standards
of performance are set forth in Article 5 (9VAC5-50-400 et seq.) of this part,
shall be performance tested by appropriate reference methods unless the board
(i) specifies or approves, in specific cases, the use of a reference method
with minor changes in methodology; (ii) approves the use of an equivalent
method; (iii) approves the use of an alternative method the results of which
the board has determined to be adequate for indicating whether a specific
source is in compliance; (iv) waives the requirement for performance tests
because the owner of a source has demonstrated by other means to the board's
satisfaction that the affected facility is in compliance with the standard; or
(v) approves shorter sampling times and smaller sample volumes when
necessitated by process variables or other factors. In cases where no
appropriate reference method exists for a new or modified source subject to a
standard of performance for volatile organic compounds, the test methods in
9VAC5-20-121 may be considered
appropriate.
B. Performance testing
for new or modified sources shall be subject to testing guidelines approved by
the board. Procedures may be adjusted or changed by the board to suit specific
sampling conditions or needs based upon good practice, judgment and experience.
When such tests are adjusted, consideration shall be given to the effect of
such change on established standards. Tests shall be performed under the
direction of persons whose qualifications are acceptable to the
board.
C. Performance tests for new
or modified sources shall be conducted under conditions which the board shall
specify to the owner based on representative performance of the source. The
owner shall make available to the board such records as may be necessary to
determine the conditions of the performance tests. Operation during periods of
startup, shutdown and malfunction shall not constitute representative
conditions for the purpose of a performance test. During the initial
performance test, emissions in excess of the level of the applicable emission
limit during periods of startup, shutdown, and malfunction shall not be
considered a violation of the applicable emission limit unless otherwise
specified in the applicable standard.
D. An owner may request that the board
determine the opacity of emissions from a new or modified source during the
performance tests required by this section.
E. Unless specified otherwise in the
applicable standard, each performance test for a new or modified source shall
consist of three separate runs using the applicable test method. Each run shall
be conducted for the time and under the conditions specified in the applicable
standard. For the purpose of determining compliance with an applicable standard
the arithmetic mean of the results of the three runs shall apply. In the event
that a sample is accidentally lost or if conditions occur in which one of the
three runs must be discontinued because of forced shutdown, failure of an
irreplaceable portion of the sample train, extreme meteorological conditions or
other circumstances beyond the owner's control, compliance may, upon the
approval of the board, be determined using the arithmetic mean of the results
of the two other runs.
F. The board
may test emissions of air pollutants from any new or modified source. Upon
request of the board the owner shall provide, or cause to be provided,
performance testing facilities as follows:
1.
Sampling ports adequate for test methods applicable to such source. This
includes (i) constructing the air pollution control system such that volumetric
flow rates and pollutant emission rates can be accurately determined by
applicable test methods and procedures and (ii) providing a stack or duct with
acceptable flow characteristics during performance tests, as demonstrated by
applicable test methods and procedures.
2. Safe sampling platforms.
3. Safe access to sampling
platforms.
4. Utilities for
sampling and testing equipment.
G. Upon request of the board, the owner of
any new or modified source subject to the provisions of this chapter shall
conduct performance tests in accordance with procedures approved by the
board.
