Robert Kaliszewski, Deputy Commissioner

Department of Energy and Environmental Protection

79 Elm Street

Hartford, CT 06106-5127

Dear Deputy Commissioner Kaliszewski:

In your letter dated November 8, 2018, the Connecticut Department of Energy and Environmental Protection (CT DEEP) requested full delegation to implement and enforce the New Source Performance Standards for Stationary Combustion Turbines at 40 CFR part 60, subpart KKKK (NSPS KKKK) for all affected sources in Connecticut.

The EPA has reviewed the pertinent regulations of the State of Connecticut and has determined they provide adequate authority and procedures for implementation of NSPS KKKK. In light of these authorities and related information in your letter dated November 8, 2018, the EPA approves your request for full delegation of authority to implement and enforce the provisions of NSPS KKKK.

This delegation of authority is subject to the following terms and conditions:

• CT DEEP will assume primary responsibility for enforcement of NSPS KKKK;
• CT DEEP will not grant a variance or waiver from compliance with applicable emission standards of NSPS KKKK;
• CT DEEP will communicate with EPA Region 1 to keep each office fully informed regarding the current compliance status of subject sources in Connecticut and interpretation of applicable regulations;
• CT DEEP will require all NSPS KKKK sources to adhere to all the reporting, monitoring, and recordkeeping requirements specified in NSPS KKKK;
• CT DEEP will notify the EPA of any variation from emission test methods and continuous emission monitoring requirements specified in NSPS KKKK. Written approval from the EPA must be obtained by CT DEEP prior to the granting or the implementation of such variations; and
• If the Regional Administrator determines that CT DEEP is not adequately implementing or enforcing NSPS KKKK, the Regional Administrator may revoke delegation of NSPS KKKK in whole or part.

Because this delegation is effective immediately, there is no need for CT DEEP to notify the EPA of its acceptance. Unless the EPA receives written notice of objection from CT DEEP within ten days from the date of this letter, CT DEEP will be deemed to have accepted all of the terms as stated herein. The EPA will publish a notice of delegation of authority in the Federal Register informing the public of this action.

The EPA appreciates CT DEEP's efforts to accept delegation to implement and enforce the provisions of NSPS KKKK. If you have any questions regarding this matter, please don't hesitate to contact Eric Wortman at (617) 918-1624.

Sincerely,

Alexandra Dapolito Dunn,

Regional Administrator
