26.11.31.00.htm 26.11.31.00. Title 26 DEPARTMENT OF THE ENVIRONMENT Subtitle 11 AIR QUALITY Chapter 31 Quality Assurance Requirements for Continuous Opacity Monitors (COMs) Authority: Environment Article, §1-101, 1-404, 2-101―2-103, 2-301―2-303, 10-102, and 10-103, Annotated Code of Maryland
26.11.31.01.htm 26.11.31.01. 01 Scope.. This chapter codifies the quality assurance (QA) and quality control (QC) procedures previously established by the Department’s Technical Memorandum 90-01 for continuous opacity monitors (COMs) The procedures are transferred into this chapter in regulatory format. In addition, the general provisions and quality control requirements found in COMAR 26.11.01.10 are also applicable to COMs.
26.11.31.02.htm 26.11.31.02. 02 Applicability.. A. The procedures specified by this chapter shall be used to evaluate the effectiveness of a facility’s quality assurance (QA) and quality control (QC) procedures for COMs. The procedures specify the minimum quality assurance requirements for the assessment and control of COM data.B. Source owners and operators using COMs shall meet these minimum requirements and are encouraged to develop and implement a more extensive QA and QC program or to continue t
26.11.31.03.htm 26.11.31.03. 03 Incorporation by Reference.. A. In this chapter, the following documents are incorporated by reference.. B. Documents Incorporated.. 1) Performance Specification 1 (PS1) under 40 CFR Part 60, Appendix B.. 2) Performance Audit Procedures for Opacity Monitors, EPA 450/4-92-010 March 1992, Atmospheric Research and Exposure Assessment Laboratory, Research Triangle Park, North Carolina 27711.
26.11.31.04.htm 26.11.31.04. 04 Definitions.. A. In this chapter, the following terms have the meanings indicated.. B. Terms Defined.. 1) “Calibration drift (CD)means the difference in the COM output reading from a reference value after a period of operation during which no unscheduled maintenance, repair, or adjustment took place. The reference value may be the simulated zero (or low-level) check or the upscale calibration value.2) “Calibration error” means the difference between the opacity values indi
26.11.31.05.htm 26.11.31.05. 05 Principle.. A. The QA procedures are a control loop composed of two functions:. 1) Assessment of data quality by measurement of COM performance; and. 2) Control and improvement of data quality by implementing QC policies and corrective actions.. B. When the assessment function indicates that data quality is inadequate, the control effort shall be increased until data quality is acceptable.C. COM Accuracy Determination.. 1) Quarterly performance audits involving a series
26.11.31.06.htm 26.11.31.06. 06 Quality Control Requirements.. A. Development and Implementation.. 1) Each source owner or operator using a COM shall develop a written quality control (QC) program and submit that program to the Department for approval.2) A source owner or operator may periodically revise its QC program to make it more effective and efficient. Each revised QC program shall be resubmitted to the Department for approval, along with the prior approved program.
26.11.31.07.htm 26.11.31.07. 07 Opacity Calibration Drift Assessment.. A. Calibration Drift (CD) Requirement.. 1) Source owners and operators using COMs shall check, record, and quantify the CD at two opacity values at least once daily in accordance with the method prescribed by the manufacturer.2) The COM calibration shall, at a minimum, be adjusted whenever the daily zero (or low-level) CD or the daily high-level CD exceeds the limits specified in Performance Specification 1 (PS1) in Append
26.11.31.08.htm 26.11.31.08. 08 Audit Frequency.. A. Each COM shall undergo a performance audit at least once each calendar quarter. Successive quarterly performance audits shall not occur within 2 months.B. A zero alignment audit shall be conducted at least annually, with each coming before a corresponding quarterly performance audit. Successive zero alignment audits shall not occur within consecutive quarters.C. When conducting a performance or zero alignment audit, the owner or operator shall use the same o
26.11.31.09.htm 26.11.31.09. 09 Performance Audit.. A. Each performance audit shall include a series of checks of individual monitoring system components and factors affecting the accuracy of the monitoring data.B. Calculations for COM data shall be in accordance with monitor specific calculations in the EPA document Performance Audit Procedures for Opacity Monitors, which is incorporated by reference in Regulation .03B(2) of this chapter. Examples of detailed audit procedures are also found in that referen
26.11.31.10.htm 26.11.31.10. 10 Calibration Error Methods.. A. Test Methods.. 1) For both calibration error methods in Regulation .09C(7) of this chapter, three filters shall each be placed in the light path five times and the monitor responses shall be determined from the permanent data recorder.2) The low- mid- and high-range calibration error results are computed as the main difference and the 95 percent confidence interval for the difference between the expected and actual responses of the
26.11.31.11.htm 26.11.31.11. 11 Zero Alignment Audit.. A. General Requirements.. 1) A zero alignment audit conducted in accordance with Regulation .08B of this chapter shall compare the monitor responses to the simulated zero check and the actual clear path condition. Primary and alternate methods for performing the zero alignment audit are described in §A(2) and (3) of this regulation.2) Primary Zero Alignment Method.. a) The primary zero alignment method shall be performed under clear path co
26.11.31.12.htm 26.11.31.12. 12 Corrective Actions.. A. Unacceptable Audit Results ― Single Performance Audit.. 1) If the COM is out-of-control, the owner or operator shall take necessary corrective action to eliminate the problem.2) Following corrective action, the owner or operator, at a minimum, shall conduct a COM performance audit on the portion of the criteria that failed to indicate the COM is operating properly.3) The COM operator shall include both the audit results showing the COM to
