   Background
The EPA proposed National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating EGUs on May 3, 2011. The public comment period ended on August 4, 2011. The company, CONSOL Energy, Inc., submitted comments on the proposed rule. CONSOL states, in part:
           "EPA did not use all the data available to it in calculating the MACT floor. There are 98 plants . . . that submitted Part II Hg emission data, but these plants are not in the list of 202 plants (338 units) in the MACT floor spreadsheet. . . EPA has not provided a reason to exclude the data from 98 plants, nor discussed this data in any way. . . EPA failed to provide any reason for excluding these 98 plants. . . It is incumbent upon EPA to evaluate those data and explain why they were not used, and to do similar analyses and provide explanation if data were excluded for the other HAPs and HAP surrogates. . . The statue [sic] requires EPA to use all available emissions information. Since EPA cannot simply exclude those data without explanation, and since the public is entitled to view and comment upon the Agency's bases for that exclusion, EPA is obligated to provide that information and to take comment on it before it finalizes this rule."
   This memorandum addresses the reason(s) for exclusion of the mercury emission test data provided by the above-mentioned 98 facilities from the MACT floor analysis for mercury.
   Discussion
   In order to process the large amount of emission test data submitted in response to the ICR, RTI developed a Microsoft Access database to store the raw data provided by the companies, and developed a series of database queries to calculate the emission factors (lb/MMBtu) necessary to conduct the MACT floor analysis. In the data analysis process (database queries), many stipulations were placed on the test data to ensure that the analysis included only those tests reports representing current EGU configurations. The five bullets listed below describe the criteria by which some emission tests were excluded from the MACT floor analysis spreadsheets.
   There are instances, noted below, where some data were not included in the MACT floor output for the EGU proposal, but are included in the current MACT floor output for the promulgated rule. The database queries used to develop the emission factors have been refined to include additional emission tests, as appropriate.
      * Emission rate, but no process data.
      An emission test was excluded if the pollutant emissions were provided in units of an emission rate (e.g., pounds per hour), but the necessary process information was not provided to calculate an emission factor. Either the unit load (MW) during testing or the fuel flow rate (lb/hour) and fuel heating value (Btu/lb) during testing were needed in addition to the emission rate.
      * Concentration, but insufficient flue gas parameters.
An emission test was excluded if the pollutant emissions were provided in units of concentration, but not enough sampling run data was provided to calculate an emission factor. The equations contained in EPA Method 19 were used to convert concentrations to emission factors. The additional pieces of data necessary to make the conversion included fuel type, concentration units that could be converted to pounds per dry standard cubic foot, percent oxygen or percent carbon dioxide, and moisture content of the flue gas.
      Additionally, facilities that burned exactly a 50/50 split of the fuels during testing were excluded, as the automated process was developed to consider just one primary fuel.
      * Test data prior to installation of current emission controls.
An emission test was excluded if the test report end date was not provided by the company. In order to accurately represent the emissions from EGUs as they are currently configured and operating, any emission tests that were completed prior to the latest air pollution control device installation date were excluded. For example, if a company provided emission test reports from March 2006 and March 2009, and installed an activated carbon injection system in 2008, then only the March 2009 test would appear in the MACT floor output.
      In the process for the February output, the test date was chosen from one field in the ICR database. If this field was not populated, then the test report was excluded. Since the February output, the process has been modified to include more reports by pulling in dates from more fields (there are several fields from which the test date can be determined). As a result, additional tests are now included in the MACT floor output.
      Additionally, for the February output, for facilities that have no add-on emission control devices, there is no control installation date, so these reports were excluded. Since the February output, the output queries have been modified to include these reports. 
      Since the February output was created, another change to the database has been to denote future controls as any control with a start date of 1/1/2010 or later. These controls were not considered in determining the latest configuration control date. 
      * Sampling port not after last control.
Multiple sampling ports could have been selected for a test; however, results from only one sampling port were selected. The sampling port selected had to be located after the last emission control device and had to be the last port for which data were provided. For example, if a company provided test results for the inlet to their wet scrubber (the last control in their configuration), a sampling port at the bottom of the stack, and a sampling port at the top of their stack, then only the test results from the sampling port at the top of their stack would be used.
An emission test was excluded if the sampling port chosen for the test was not part of the configuration chosen for the test (i.e., the sampling port was not included in the "current" configuration for the unit). In the electronic ICR, there was a mandatory field for the sampling port to be selected and an optional field for the configuration to be selected for each test. In tests from a few facilities, the company did not select a sampling port that was part of the configuration they selected. These test results were excluded.
      * Yellowstone Energy (specific facility cited by commenter).
The Yellowstone Energy LP facility (ORIS Code 50931) results are, in fact, included in the MACT floor analysis. The data are included in the petroleum coke spreadsheet because the primary fuel during testing was reported to be petroleum coke. 
   Conclusion
   Table 1 presents a summary of the reasons emissions tests were excluded from the MACT floor analysis at proposal, and provides counts of facilities excluded for each reason. Table 1 also presents the number of previously excluded facilities that have been added to the MACT floor analysis for promulgation due to refinements in the database queries.
   The attached Table A-1 (in Attachment 1) lists the 98 facilities that were excluded from the mercury MACT floor analysis at proposal. Table A-1 includes the reason each of these emission tests was excluded from the MACT floor analysis at proposal. An additional column identifies the emission tests that are now included in the MACT floor analysis due to refinements in the database queries since proposal.
