Virginia Administrative Code › Title 9 - ENVIRONMENT › Agency 5 - STATE AIR POLLUTION CONTROL BOARD › Chapter 45 - CONSUMER AND COMMERCIAL PRODUCTS › Part I - Special Provisions › Section 9VAC5-45-40 - Monitoring

Current through Register Vol. 40, No. 24, July 15, 2024
A. Unless otherwise
				  approved by the board, owners or other persons subject the provisions of an
				  standard under this chapter shall install, calibrate, maintain, and operate
				  systems for continuously monitoring and recording emissions of specified
				  pollutants as specified in the applicable article of this chapter. However,
				  nothing in this chapter shall exempt any owner from complying with subsection F
				  of this section.
B. All continuous
				  monitoring systems and monitoring devices shall be installed and operational
				  prior to conducting emission tests required under
				  9VAC5-45-30. Verification of
				  operational status shall, as a minimum, include completion of the
				  manufacturer's written requirements or recommendations for installation,
				  operation, and calibration of the device and completion of any conditioning
				  period specified by the appropriate specification in Appendix B of 40 CFR Part
				  60.
C. During any emissions tests
				  required under
				  9VAC5-45-30 or within 30 days
				  thereafter and at such other times as may be requested by the board, the owner
				  or other person subject to the requirements of subsection A of this section
				  shall conduct continuous monitoring system performance evaluations and furnish
				  the board within 60 days of them two or, upon request, more copies of a written
				  report of the results of such tests. These continuous monitoring system
				  performance evaluations shall be conducted in accordance with the requirements
				  and procedures specified in the applicable emission standard, the requirements
				  contained in applicable procedures in
				  9VAC5-20-121, and the requirements
				  and procedures equivalent to those contained in the appropriate specification
				  of Appendix B of 40 CFR Part 60.
D.
				  Unless otherwise approved by the board, all continuous monitoring systems
				  required by subsection A of this section shall be installed, calibrated,
				  maintained, and operated in accordance with (i) applicable requirements in this
				  section, (ii) requirements in the applicable emission standard, and (iii)
				  requirements equivalent to those in
				  40 CFR
				  60.13.
E. After receipt and consideration of written
				  application, the board may approve alternatives to any monitoring procedures or
				  requirements of this chapter including, but not limited to, the following:
1. Alternative monitoring requirements when
				  installation of a continuous monitoring system or monitoring device specified
				  by this chapter would not provide accurate measurements due to liquid water or
				  other interferences caused by substances within the effluent gases.
2. Alternative monitoring requirements when
				  the source is infrequently operated.
3. Alternative monitoring requirements to
				  accommodate continuous monitoring systems that require additional measurements
				  to correct for stack moisture conditions.
4. Alternative locations for installing
				  continuous monitoring systems or monitoring devices when the owner can
				  demonstrate the installation at alternate locations will enable accurate and
				  representative measurements.
5.
				  Alternative methods of converting pollutant concentration measurements to units
				  of the standards.
6. Alternative
				  procedures for computing emission averages that do not require integration of
				  data (e.g., some facilities may demonstrate that the variability of their
				  emissions is sufficiently small to allow accurate reduction of data based upon
				  computing averages from equally spaced data points over the averaging
				  period).
7. Alternative monitoring
				  requirements when the effluent from a single source or the combined effluent
				  from two or more sources are released to the atmosphere through more than one
				  point.
8. Alternative procedures
				  for performing calibration checks.
9. Alternative monitoring requirements when
				  the requirements of this section would impose an extreme economic burden on the
				  owner.
10. Alternative monitoring
				  requirements when the continuous monitoring systems cannot be installed due to
				  physical limitations at the source.
