9 Va. Admin. Code § 5-40-30 - Emission testing
A.
Emission tests for existing 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. In cases where no
appropriate reference method exists for an existing source subject to an
emission standard for volatile organic compounds, the applicable test method in
9VAC5-20-121 may be considered
appropriate.
B. Emission testing
for existing 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
existing 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. An owner
may request that the board determine the opacity of emissions from an existing
source during the emission tests required by this section.
E. Each emission test for an existing source
shall consist of three separate runs using the applicable test method. Each run
shall be conducted for the time and under the conditions acceptable to the
board. 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 existing 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.
G. Upon request of the board the owner of any
existing source subject to the provisions of this chapter shall conduct
emission tests in accordance with procedures approved by the board.
