The purpose oftoday's hearing is to give the public an opportunity to commenton proposed minor administrative corrections to the Department's opacity regulations that became effective on May 17, 2010 Summary The Department's opacity regulations include the general Continuous Opacity Monitor (COM) and Continuous Emission Monitor (CEM) requirements in COMAR 26
. 11
.01.10 and .11, definitions in COMAR 26.11.09 and the requirements in COMAR 26.11.09
.05 thatprovide the procedures for demonstrating compliance with visible emissions requirements using COM data
. The opacity regulations became effective on May 17,2010, but continued to reference Technical Memorandum 90-01 for quality assurance procedures
. The regulations must be administratively complete before they are submitted to EPA to be included in the approved SIP and becomefederally enforceable. The opacity regulations are a first effortmoving away from the Department's TM 90-01 that contains enforcement policies used to detennine compliance with visible emissions requirements for sources that use COMs. COMAR 26.11.09.05 was expanded to include specific compliance procedures as they apply to fuel burning equipment. Two other source categories that use COMs will be addressed in the future. The two categories are municipal waste combustors and Portland cement manufacturing plants. Sources Affected These amendments affect only owners oflarge fuel burning equipment required to install and operate COMs. Requirements These amendments are minor administrative corrections that are necessary before submitting the regulations to EPA
. These amendments include: 1. In COMAR 26.11.01.10A(1)(e) and : 1tA(l)(b), correct the size ofa MWC required to install continuous monitors; 2
. In COMAR 26.11
.01.1OC(S), clarify that the QA/QC for COMs is now located in new COMAR 26.11.31; 3. In COMAR 26.11.01.11 8(3), clarify the pollutants to be continuously measured for MWCs, Kraft pulp mills, and fluidized bed combustors; 4. In COMAR 26.11.09.05A(4)(d), correctthe size ofthe low capacity factor units; 5. In COMAR 26.11.09.05A(5) and (6), reinstate the paragraphs that were inadvertently omitted relating to the use ofMethod 9 observations and the impact ofexcess emissions on ambient air; and 6. In COMAR 26.11.09E, correct the references to reflect the relocation ofthis Section. Submission to EPA as Revision to Maryland's SIP This action will be submitted to the U.S. Environmental Protection Agency (EPA) for approval as part ofMaryland's State Implementation Plan.
