Notice of public meeting and extension of public comment period.


On December 7, 2010, EPA published a notice announcing reconsideration of the March 3, 2010, final national emission standards for hazardous air pollutants for reciprocating internal combustion engines and requesting public comment on one issue arising from the final rule. Specifically, EPA requested public comment on the 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. In order to provide further opportunity for public participation, EPA has scheduled a public meeting in Research Triangle Park, North Carolina, for January 13, 2011. More information on the location is shown in SUPPLEMENTARY INFORMATION. In addition, EPA is extending the deadline for the written comments on issue under reconsideration to February 14, 2011.
