AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of reconsideration of final rule; request for public comment; notice of public meeting.

SUMMARY:

On March 3, 2010, EPA published final national emission standards for hazardous air pollutants for existing compression ignition stationary reciprocating internal combustion engines. Subsequently, the Administrator received two petitions for reconsideration concerning one particular issue arising from the final rule. EPA is announcing our reconsideration of and requesting public comment on that one issue. Specifically, while EPA is not proposing at this time any specific changes to our regulations, EPA is requesting comment on our decision to amend the limitations on operation of emergency stationary engines to allow emergency engines to operate for up to 15 hours per year as part of an emergency demand response program. EPA plans to issue a final decision on this issue as expeditiously as possible. EPA is seeking comment only on this issue. EPA will not respond to any comments addressing any other issue or any other provisions of the final rule or any other rule.

II. Background

On March 3, 2010, EPA promulgated national emission standards for hazardous air pollutants (NESHAP) for existing stationary compression ignition (CI) reciprocating internal combustion engines (RICE) (75 FR 9648). The final NESHAP for stationary RICE were promulgated under 40 CFR part 63, subpart ZZZZ, which already contained standards applicable to new stationary RICE and some existing stationary RICE. The final CI RICE NESHAP is available at http://www.regulations.gov/​search/​Regs/​home.html#documentDetail?​R=​0900006480ab3523.

Following promulgation of the March 3, 2010, final rule, the EPA Administrator received a petition for reconsideration, dated April 30, 2010, from the Delaware Department of Natural Resources and Environmental Control (DE DNREC) pursuant to section 307(d)(7)(B) of the CAA. The EPA Administrator also received a petition for reconsideration, dated May 27, 2010, from CPower Inc., EnergyConnect Inc., EnerNOC Inc., and Innoventive Power LLC (EnerNOC, et al.) pursuant to section 307(d)(7)(B) of the CAA. On August 2, 2010, EPA issued a letter to the counsels for the DE DNREC and EnerNOC, et al. granting the petitions for reconsideration and indicating that the Agency would issue a Federal Register notice regarding the reconsideration process. This action requests comment on issues raised in the petitions for reconsideration.

In addition to the petitions for reconsideration, one petition for judicial review of the March 3, 2010, final NESHAP for existing stationary CI RICE was filed with the U.S. Court of Appeals for the District of Columbia Circuit by EnerNOC, et al. (Doc. No. 10-1090, D.C. Cir). On June 3, 2010, EPA filed an unopposed motion to hold the case in abeyance while the Agency considers the pending administrative petitions for reconsideration. On June 4, 2010, the Court granted EPA's motion and ordered the case held in abeyance pending further order from the Court. The petitions for reconsideration are available for review at http://www.regulations.gov/​search/​Regs/​home.html#documentDetail?​R=​0900006480af3dd6 and http://www.regulations.gov/​search/​Regs/​home.html#documentDetail?​R=​0900006480afedbd.

III. Discussion of the Issue

On March 5, 2009, EPA proposed NESHAP for several categories of existing stationary RICE (74 FR 9698). That proposed rule made revisions to 40 CFR part 63, subpart ZZZZ. The pre-existing subpart ZZZZ stated that emergency stationary RICE did not include engines that supply power to an electric grid or otherwise provide power as part of a financial arrangement with another entity. The proposed rule did not change the definition, but specified certain use requirements for existing emergency stationary RICE.

EPA received comments on the proposed rule recommending that emergency stationary RICE be allowed to participate in emergency demand response programs to ensure stability of the electric grid. Based on the comments, EPA determined that it would be appropriate to allow emergency engines to operate as part of emergency demand response programs for a limited number of hours of operation per year in situations where grid failure and a blackout are imminent. EPA included a provision in the March 3, 2010, final rule specifying that emergency engines could be operated for a maximum of 15 hours per year as part of a demand response program if the regional transmission organization or equivalent balancing authority and transmission operator has determined there are emergency conditions that could lead to a potential electrical blackout, such as unusually low frequency, equipment overload, capacity or energy deficiency, or unacceptable voltage level.

Following promulgation of the final rule, EPA received two petitions for reconsideration regarding the allowance for operation of emergency engines in emergency demand response programs. The petition from DE DNREC requested that EPA reconsider the decision to allow 15 hours of emergency demand response operation for emergency engines because of the adverse impacts of the increased emissions from these engines. According to the DE DNREC, the emergency demand response operation would likely occur on high ozone days, and would undercut the progress Delaware has made in reducing emissions of hazardous air pollutants, nitrogen oxides, volatile organic compounds, and ozone. The DE DNREC also stated that there was insufficient notice that EPA would amend the provisions for stationary emergency engines.

The petition from EnerNOC, et al. requested that EPA revise the allowance for emergency demand response operation in the final rule to allow the engines to be operated for a maximum of 60 hours per year or the minimum hours required by the Independent System Operator (ISO) tariff, whichever is less. In the opinion of EnerNOC, et al., the final rule may prevent emergency engines from participating in emergency demand response programs since the engines may not be able to meet ISO tariff requirements that specify minimum hours of availability to participate. According to the petition from EnerNOC, et al., emergency engines have historically been called to operate for emergency demand response on a very limited basis. The EnerNOC, et al. petition provided a summary of the historical usage of engines in emergency demand response programs. The petitioners were of the opinion that emergency demand response programs provide a benefit to the environment by preventing rotating or wholesale blackouts, which would result in the operation of all emergency engines in the affected area.Start Printed Page 75940

IV. Solicitation of Public Comment and Participation

EPA seeks full public participation in arriving at its final decisions. At this time EPA is not proposing any specific revisions to our regulations allowing 15 hours for emergency stationary RICE in emergency demand response programs in the final NESHAP for stationary RICE. However, EPA requests public comment on the regulations delineating the allowance to assess whether those regulations should be revised. EPA requests comment on whether or not engines should be allowed to participate in emergency demand response programs, while keeping their status as emergency engines under the regulations, and if they are allowed to participate, what, if any, limitations should be placed on the operation of emergency engines in emergency demand response programs. EPA specifically requests comment on whether emergency engines in emergency demand response programs should be limited to use during periods in which the regional transmission organization or equivalent balancing authority and transmission operator directs the implementation of operating procedures for voltage reductions of 5 percent of normal operating voltage requiring more than 10 minutes to implement, voluntary load curtailments by customers, or automatic or manual load-shedding, in response to, or to prevent the occurrence of, unusually low frequency, equipment overload, capacity or energy deficiency, unacceptable voltage levels, or other such emergency conditions. EPA also requests comment on whether the limitation on use should be for periods in which the regional transmission authority or equivalent balancing authority has declared an Energy Emergency Alert Level 2 (EEA Level 2) as defined in the North American Electric Reliability Corporation Reliability Standard EOP-002-3, Capacity and Energy Emergency.

EPA is also requesting information on whether the operation of these engines in emergency demand response programs is needed to ensure the stability of the electric grid. EPA is seeking comment on whether the costs for meeting the requirements for non-emergency engines would prevent these engines from taking part in emergency demand response programs.

In addition, EPA is requesting information on the environmental impact of the operation of these engines. EPA is interested in information on the typical frequency and duration of the operation of these engines in emergency demand response programs and whether their operation tends to occur on high ozone days.

EPA recently published a notice of proposed rulemaking to revise portions of the New Source Performance Standards for Stationary Compression Ignition and Stationary Spark Ignition Internal Combustion Engines. 75 FR 32612 (June 8, 2010). In that action, EPA proposed revising the definition and use restrictions on emergency stationary internal combustion engines in 40 CFR part 60, subparts IIII and JJJJ, to correspond to the definition of emergency RICE and the restrictions on emergency RICE finalized in the March 3, 2010, final NESHAP for existing stationary CI RICE. Therefore, the comments received on this issue in both proceedings may be relevant to one another.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

This action is not a “significant regulatory action” under the terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is therefore not subject to review under the Executive Order.

B. Paperwork Reduction Act

This action does not impose any new information collection burden. EPA is not proposing any new information collection activities (e.g., monitoring, reporting, recordkeeping) as part of this action. With this action, EPA is seeking additional comments on one aspect of the final NESHAP for existing stationary CI RICE (75 FR 9648, March 3, 2010). The Office of Management and Budget (OMB) has previously approved the information collection requirements contained in the existing regulations under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB control number 2060-0548. The OMB control numbers for EPA's regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

The Regulatory Flexibility Act generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

For purposes of assessing the impacts of this action on small entities, small entity is defined as: (1) A small business as defined by the Small Business Administration's regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.

After considering the economic impacts of this action on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. This action seeks comment on one aspect of the final NESHAP for existing stationary CI RICE without proposing any changes to the rule, and it does not impose any new requirements.

D. Unfunded Mandates Reform Act of 1995

This action contains no Federal mandates under the provisions of Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531-1538 for State, local, or tribal governments or the private sector. The action imposes no enforceable duty on any State, local or tribal governments or the private sector. Therefore, this action is not subject to the requirements of sections 202 or 205 of the UMRA.

This action is also not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. This action requests comment on one aspect of the final NESHAP for existing stationary CI RICE without proposing any changes to the rule

E. Executive Order 13132: Federalism

This action does not have federalism implications. It will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. This action seeks comment on one aspect of the final NESHAP for existing stationary CI RICE without proposing any changes to the rule. Thus, Executive Order 13132 does not apply to this action.Start Printed Page 75941

F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments

This action does not have tribal implications, as specified in Executive Order 13175 (65 FR 67249, November 9, 2000). This action will not have substantial direct effects on tribal governments, on the relationship between the Federal government and Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this action.

G. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks

EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) as applying to those regulatory actions that concern health or safety risks, such that the analysis required under section 5-501 of the Order has the potential to influence the regulation. This action is not subject to Executive Order 13045 because it is based solely on technology performance and not on health or safety risks.

H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use

This action is not subject to Executive Order 13211 (66 FR 28355 (May 22, 2001)), because it is not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act

Section 12(d) of the National Technology Transfer and Advancement Act (NTTAA) of 1995 (Pub. L. 104-113, Section 12(d), 15 U.S.C. 272 note) directs EPA to use voluntary consensus standards (VCS) in its regulatory activities, unless to do so would be inconsistent with applicable law or otherwise impractical. The VCS are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by VCS bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency does not use available and applicable VCS.

This action does not involve technical standards. Therefore, EPA did not consider the use of any VCS.

J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations

Executive Order 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects on minority or low-income populations.

EPA has determined that this action will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations because it does not affect the level of protection provided to human health or the environment. This action seeks comment on one aspect of the final NESHAP for existing stationary CI RICE without proposing any changes to the rule.
