ECMPS Reporting Requirements under the MATS Rule. Stakeholder Meeting---Raleigh, NC May 2013 Charles Frushour USEPA, CAMD. Background.
Stakeholder Meeting---Raleigh, NC
**That is, units that commence construction or reconstruction after May 3, 2011 (see §63.9985).
**For common stack configurations, if testing is done at the common stack, the potential annual Hg mass emissions must not exceed 29.0 lb times the number of units that share the stack.
**If emissions averaging is used, compliance is determined on a 90 boiler operating day basis (see §63.10009).
**Note: The electronic and hardcopy monitoring plan information for the auxiliary monitoring systems may have been previously submitted to satisfy the requirements of the Acid Rain Program, CAIR, or RGGI. If so, no additional monitoring plan submittals are required for these systems.
**The CAMR rule was vacated by the DC Court of Appeals in 2008.
@ If emissions averaging is used, the initial averaging period is 90 operating days.
**That is, no later than180 days after April 16, 2015 (for existing units) and no later than180 days after the later of April 16, 2012 or unit startup (for new units).
** 90 boiler operating days if emissions averaging is used.
** Or, if applicable, 90 boiler operating day rolling average Hg emission rates.
@ See the footnote on the next slide
** The MATS rule requires one variation from Part 75 QA for the SO2 monitor. Linearity checks are required for SO2 span values of 30 ppm or less.
**Note:The MATS rule requires one variation from the QA test requirements of Part 75. If the SO2 CEMS has a span value of 30 ppm or less, you must perform linearity checks in accordance with section 2.2 of Appendix B to Part 75.
@The monitoring plan and EDRs are basically the same as the ones required under the Acid Rain and CAIR SO2 Programs. The only new information in the monitoring plans and reports will be formulas to convert SO2 concentrations from ppm to the units of the MATS standard and hourly SO2 emission rates expressed in those units.
**Note that only liquid oil-fired EGUs have HF limits---there are no HF standards for coal- or petroleum coke-fired EGUs.
** Note that PS 15 applies only to FTIR analyzers. EPA intends to issue a technology-neutral performance specification for HCl CEMS and to amend Appendix B accordingly (see Appendix B, section 3.1).
@Currently the draft ECMPS instructions does not identify all of the QA information described in PS 15 and sections 5.1.1 through 5.1.3 of Appendix B to Subpart UUUUU. Special records will have to be created for this purpose.
