The Environmental Protection Agency plans to reconsider parts of its final rule limiting emissions of hazardous air pollutants from small reciprocating internal combustion engine (RICE) diesel generators. In a June 28 letter, EPA Assistant Administrator for Air and Radiation Gina McCarthy said the agency is granting reconsideration to provide an opportunity for public comment on three specific provisions that were added in response to public comments on its proposed rule.

The three issues to be reconsidered are:
  • the timing of a requirement that certain emergency backup generators that operate for more than 15 hours per year use ultra low-sulfur diesel beginning in 2015;
  • the timing and information required in annual reports for operators of RICE units that operate, or commit to operate, for more than 15 hours per year; and
  • conditions for operation of RICE units for up to 50 hours per year for non-emergencies as part of a financial arrangement with another entity.
EPA is continuing to review the other issues raised in petitions for reconsideration of the RICE rule, McCarthy said in the letter to the Delaware Department of Justice.
