Virginia Administrative Code › Title 9 - ENVIRONMENT › Agency 5 - STATE AIR POLLUTION CONTROL BOARD › Chapter 60 - HAZARDOUS AIR POLLUTANT SOURCES › Part I - Special Provisions › Section 9VAC5-60-30 - Emission testing

Current through Register Vol. 40, No. 24, July 15, 2024
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.
