#### Regulation .08 Requirements for an Existing Large MWC with a Capacity Greater Than 250 Tons Per Day.

*COMAR 26.11.08.08*

A. Emission Standards and General Requirements.

  (1) A person who owns or operates an existing large MWC subject to this regulation may not violate any of the emission standards or general requirements in §A(2) of this regulation after the compliance date in §§A and D of this regulation.

  (2) Emission Standards and General Requirements.

  (3) The standards in §A(2) of this regulation apply at all times except during periods of startup, shutdown, or malfunction as provided in 40 CFR §60.58b(a).

* Corrected to 7 percent oxygen on dry basis. If a CO2 monitor is selected as the dilutent monitor it must meet the requirements of 40CFR §60.58b(b)(6).

B. Monitoring Requirements.

  (1) A person who owns or operates an existing MWC subject to this regulation shall:

    (a) Install, calibrate, operate, and maintain continuous monitors for carbon monoxide, oxygen, opacity, oxides of nitrogen, and sulfur dioxide;

    (b) Locate monitors downstream of the final air pollution control device to measure concentrations of oxygen, oxides of nitrogen, sulfur dioxide, and opacity of the exhaust gases;

    (c) Install, operate, and maintain at a minimum, one temperature monitor to measure the temperature of the flue gas as it enters the particulate matter air pollution control device; and

    (d) Meet the specifications in §A(2) of this regulation if an alternative monitoring or sampling method of compliance is selected in lieu of a stack test.

  (2) If the percent removal option is to be used to show compliance with §B(1)(b) of this regulation, sulfur dioxide and oxygen monitors shall also be located upstream of the pollution control device. Monitors shall be located at the combustor outlet exit to measure concentrations of carbon monoxide.

  (3) The monitors required by §B(1)(a) and (b) of this regulation shall meet the installation, certification, reporting, record-keeping, and other requirements of COMAR 26.11.01.10, and 26.11.01.11, performance specifications in 40 CFR Part 60, Appendix B, the quality assurance procedures in 40 CFR Part 60, Appendix F, all requirements in 40 CFR §60.58b, COMAR 26.11.31.

  (4) A person shall apply for and receive written approval from the Department before installing any of the monitors required in this chapter.

C. Reporting and Record-Keeping Requirements.

  (1) A person who owns an existing MWC subject to this regulation shall report and maintain records in accordance with 40 CFR §60.59b of Subpart Eb, as applicable, except for the siting requirements under §60.59b(a), (b)(5), and (d)(11) of 40 CFR Part 60, Subpart Eb;

  (2) Continuous monitoring data reduction and data availability shall be as prescribed in COMAR 26.11.01.10 and 26.11.01.11. If there is any inconsistency between COMAR 26.11.01.10 and 26.11.01.11 and 40 CFR 60, the requirements of 40 CFR 60 govern.

D. Compliance Schedule and Date.

  (1) A person who owns or operates an existing large MWC subject to this chapter shall comply with the standards in §A(2) of this regulation, according to the applicable schedule in §D(2)—(6).

  (2) A person who owns or operates an existing large MWC subject to this chapter and is not planning an extensive emission control system upgrade shall submit a plan by October 1, 2007, to the Department that describes the increments of progress to be achieved as follows:

    (a) Not later than December 1, 2007 — release purchase orders for initial testing and modifications;

    (b) Not later than April 1, 2008 — begin modification and testing of control systems;

    (c) Not later than September 1, 2008 — end modifications and debug system;

    (d) Not later than December 1, 2008 — submit stack test protocol and test schedule; and

    (e) On and after April 28, 2009 — achieve full compliance with the standards.

  (3) A person who owns or operates an existing large MWC subject to this chapter and is planning an extensive emission control system upgrade shall submit a plan, containing an expeditious compliance schedule, for review and approval by the Department, that:

    (a) Describes the control method to be used to achieve compliance with the applicable requirements;

    (b) Includes a complete application for a permit to construct the control system and compliance schedule to the Department not later than September 1, 2008; and

    (c) If approved, includes in the compliance schedule a schedule which is no less stringent than the increments of progress in §D(4) of this regulation.

  (4) The following increments of progress shall be achieved if an extensive emission control system upgrade is planned:

    (a) Not later than April 1, 2008 — complete control system and cost analysis;

    (b) Not later than December 1, 2008 — release purchase orders for the purchase of primary components;

    (c) Not later than April 1, 2009 — begin construction of control systems;

    (d) Not later than September 1, 2010 — end construction, startup and debug system;

    (e) Not later than December 1, 2010 — submit stack test protocol and test schedule; and

    (f) Not later than March 10, 2011 — achieve full compliance.

  (5) The interim dates in §D(2) and (4) of this regulation may be delayed upon approval by the Department and the U.S. EPA if the compliance dates of April 28, 2009, and March 10, 2011, are met.
