In accordance with 5 CFR 1320, OMB is withholding approval at this time. Prior to publication of the final rule, the agency must submit to OMB a summary of all comments related to the information collection contained in the proposed rule and the agency response. The agency should clearly indicate any changes made to the information collection as a result of these comments.

Potential respondents are owners and operators of new fossil fuel-fired EGUs greater than 25 megawatt electric. The proposed standards would establish standards of performance for CO2 emissions from EGUs currently in the 40 CFR part 60, Da and KKKK source categories under a new subpart TTTT. Subpart Da currently regulates utility boilers, and subpart KKKK currently regulates stationary combined cycle units and IGCC units. The proposed requirements would require affected EGUs to meet an output-based standard of 1,000 lb CO2/MWh, based on the performance of widely used NGCC technology. Reflecting the economics of the energy sector, NGCC is likely to be the predominant choice for new fossil fuel-fired generation even absent this rule. New coal-fired units could meet the standard either by employing CCS of approximately 50% of the CO2 in the exhaust gas at startup, or through later application of more effective CCS to meet the standard on average over a 30-year period. This proposed action would impose minimal new information collection burden on affected sources beyond what those sources would already be subject to under the authorities of CAA parts 75 and 98. Apart from certain reporting costs based on requirements in the NSPS General Provisions (40 CFR part 60, subpart A), which are mandatory for all owners/operators subject to CAA section 111 national emission standards, there are no new information collection costs, as the information required by this proposed rule is already collected and reported by other regulatory programs. The proposed rule would require that CO2 mass rate CEMS and the associated automatic data acquisition and handling system be installed and operated. In this rulemaking, the EPA proposes that the owner or operator of a new unit would be required to comply with the notification and recordkeeping requirements in the section 111 regulatory general provisions, 40 CFR part 60, subpart A, and would need to report results of performance testing and excess emissions; as well as record and maintain hourly average CO2 emissions concentration, hourly average flow rate, and hourly useful electrical generation. As part of an Agency-wide effort to facilitate reporting of environmental data and reports, the proposal would require that owners and operators subject to this regulation must electronically submit excess emissions, continuous monitoring systems performance and-or summary reports. The EPA does not project any new coal-fired EGUs that commence construction after this proposal to commence operation over the 3-year period covered by this ICR. We estimate that 17 new affected NGCC units would commence operation during that time period.
Program change increase is due to information collection activities that will be imposed by new subpart TTTT, Standards of Performance for GHG Emissions for New EGUs, under 40 CFR part 60.
On behalf of this Federal agency, I certify that the collection of information encompassed by this request complies with 5 CFR 1320.9 and the related provisions of 5 CFR 1320.8(b)(3).
The following is a summary of the topics, regarding the proposed collection of information, that the certification covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control number;
If you are unable to certify compliance with any of these provisions, identify the item by leaving the box unchecked and explain the reason in the Supporting Statement.
