The owner or operator of fuel-burning equipment burning coal, with a heat input capacity of 100 million Btu per hour or greater, shall install CEMs to measure and record sulfur dioxide, nitrogen oxide, either oxygen or carbon dioxide, and flow. The owner or operator of: A municipal waste combustor (MWC) shall install CEMs to measure and record SOx, NOx, carbon monoxide emissions and either CO2 or oxygen; A Kraft pulp mill shall install a CEM to measure and record SO2 and flow; and A fluidized bed combustor of any size shall install CEMs to measure and record sulfur dioxide, nitrogen oxide and either oxygen or carbon dioxide. Except as otherwise approved by the Department, if the owner or operator is unable to obtain emissions data from CEMs because of a malfunction of the CEM for more than 2 hours in duration, the owner or operator shall use the alternative measurement method approved by the Department and EPA. Quality Assurance for CEMs. A CEM used to monitor a gas concentration shall meet the quality assurance criteria of 40 CFR Part 60, Appendix F, as amended, which is incorporated by reference, or, if applicable, the quality assurance criteria of 40 CFR Part 75, Appendix B, as amended. Monitoring and Determining Compliance. General. A CEM required by this regulation is the primary method used by the Department to determine compliance or non-compliance with the applicable emission standards established in any permit or approval, administrative or court order, Certificate of Public Convenience and Necessity, or regulation in this subtitle. Data Reduction. A CEM used to monitor a gas concentration shall record not less than four equally spaced data points per hour and automatically reduce data in terms of averaging times consistent with the applicable emission standard. Record Keeping and Reporting Requirements. CEM System Downtime Reporting Requirements. All CEM system downtime that lasts or is expected to last more than 24 hours shall be reported to the Department by telephone before 10 a.m. of the first regular business day following the breakdown. The system breakdown report required by §E(1)(a) of this regulation shall include the reason, if known, for the breakdown and the estimated period of time that the CEM will be down. The owner or operator of the CEM shall notify the Department by telephone when an out-of-service CEM is back in operation and producing data that has met performance specifications for accuracy, reliability, and durability of acceptable monitoring systems, as provided in COMAR 26.11.31, and is producing data. CEM Data Reporting Requirements. All test results shall be reported in a format approved by the Department. Certification testing shall be repeated when the Department determines that the CEM data may not meet performance specifications because of component replacement or other conditions that affect the quality of generated data. A quarterly summary report shall be submitted to the Department not later than 30 days following each calendar quarter. The report shall be in a format approved by the Department, and shall include the following: The cause, time periods, and magnitude of all emissions which exceed the applicable emission standards; The source downtime including the time and date of the beginning and end of each downtime period and whether the source downtime was planned or unplanned; The time periods and cause of all CEM downtime including records of any repairs, adjustments, or maintenance that may affect the ability of the CEM to meet performance specifications of emission data; Quarterly totals of excess emissions, installation downtime, and CEM downtime during the calendar quarter; Quarterly quality assurance activities; Daily calibration activities that include reference values, actual values, absolute or percent of span differences, and drift status; and Other information required by the Department that is determined to be necessary to evaluate the data, to ensure that compliance is achieved, or to determine the applicability of this regulation. All information required by this regulation to be reported to the Department shall be retained and made available for review by the Department for a minimum of 2 years from the time the report is submitted.
