9 Va. Admin. Code § 5-60-30 - Emission testing
A.
Emission tests for hazardous air pollutant sources shall be conducted and
reported and data shall be reduced as set forth in this chapter and in the
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 emission 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.
B. Emission testing
for hazardous air pollutant 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, judgement
and experience. When such tests are adjusted, consideration shall be given to
the effect of such change on established emission standards. Tests shall be
performed under the direction of persons whose qualifications are acceptable to
the board.
C. Emission tests for
hazardous air pollutant 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 emission tests. Operations during
periods of startup, shutdown and malfunction shall not constitute
representative conditions for the purpose of an emission test. During the
initial emission 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. Each emission test for a hazardous air
pollutant 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 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.
E. The board
may test emissions of air pollutants from any hazardous air pollutant source.
Upon request of the board the owner shall provide, or cause to be provided,
emission 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 emission 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.
F. Upon request of the board, the owner of
any hazardous air pollutant source subject to the provisions of this chapter
shall conduct emission tests in accordance with procedures approved by the
board.
