Rhode Island Code of Regulations › Title 250 - Department of Environmental Management › Chapter 120 - Air Resources › Subchapter 05 - Air Pollution Control › Part 27 - Control of Nitrogen Oxide Emissions › Section 250-RICR-120-05-27.9 - Compliance Testing and Emission Monitoring Requirements

Current through June 14, 2024
A.
				  Compliance with §§27.8.1 and 27.8.7 of this Part shall be
				  demonstrated by installation calibration, maintenance and operation of a
				  continuous emission monitoring system for NOx and O2 or
				  CO2.
B.
				  Compliance with §§27.8.2(A) and (B), 27.8.3, 27.8.4, and 27.8.6 of
				  this Part shall be demonstrated either by emission testing or by installation
				  calibration, maintenance and operation of a continuous emission monitoring
				  system for NOx and O2 or
				  CO2.
C.
				  Compliance with §27.8.2(C) of this Part shall be demonstrated by record
				  keeping as specified in §
										27.10(H) 
				  of this Part.
D. Compliance with
				  the emission limitations in §27.8.1 of this Part shall be based on
				  24-average concentrations.
E.
				  Compliance with the emission limitations in §§27.8.2 and 27.8.3 of
				  this Part shall be based on one-hour average concentrations. Emission testing
				  shall consist of three (3), one-hour test runs. Compliance with the emission
				  limitation must be demonstrated utilizing the arithmetic mean of the three (3)
				  test runs.
F. Continuous emission
				  monitoring systems shall comply with the following requirements:
1. Performance specification, monitor
				  location, calibration and operating procedures, quality assurance procedures
				  for each monitor and a sample calculation showing how the concentrations from
				  the NOx CEMs will be converted in to the applicable units and averaging time of
				  the emission limit must be submitted to the Office of Air Resources for review
				  and approval at least one hundred and eighty (180) days prior to expected
				  installation.
2. All emission data
				  shall be continuously monitored and recorded.
3. The continuous emission monitors must
				  satisfy the requirements of 40 C.F.R. §
												60 Appendix B,
				  Performance Specification 2, incorporated in §
											27.4(A) of
				  this Part.
4. The continuous
				  emission monitors must satisfy the quality assurance requirements of
				  40 C.F.R. §
												60, Appendix F, incorporated in §
											27.4(A) of
				  this Part.
5. The continuous
				  emission monitoring system will be used to determine compliance with the
				  applicable allowable NOx emission rates.
6. The stationary source shall have the
				  capability of transmitting all of the collected continuous emission monitoring
				  data to the Office of Air Resources via a telemetry system.
7. Each continuous emission monitoring system
				  shall be operated at all times except for periods of CEMs calibration checks,
				  zero and span adjustment and preventative maintenance. Notwithstanding such
				  exceptions, in all cases valid CEMs data shall be obtained for at least
				  seventy-five percent (75%) of the hours per day, seventy-five (75%) of the days
				  of the month and ninety percent (90%) of the hours per quarter that the
				  stationary source is operating.
