Reciprocating Internal Combustion Engines National
Emissions Standards for Hazardous Air Pollutants
(RICE NESHAP)
The Environmental Protection Agency (EPA) has recently revised Reciprocating Internal Combustion Engines National Emissions Standards for Hazardous Air Pollutants (RICE NESHAP, 40 CFR 63, Subpart ZZZZ). Also in the same action, the EPA promulgated New Source Performance Standards (NSPS) for Stationary Compression Ignition Internal Combustion Engines (RICE NSPS, 40 CFR Part 60, Subpart IIII) and Stationary Spark Ignition Internal Combustion Engines (Subpart JJJJ).
The rule applies to all existing, new and reconstructed stationary engines at major and area sources of hazardous air pollutants. The intention of the RICE NESHAP is to reduce emissions of toxic air pollutants that collectively can have a significant impact on air quality and public health. The air toxics emitted from stationary engines include formaldehyde, acrolein, acetaldehyde, and methanol. The focus of the NSPS is to limit emissions of criteria air pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate matter (PM).
DAQ Request for Information Letter
North Carolina Division of Air Quality (DAQ) has identified permitted facilities that could be affected by the RICE NESHAP. A request for information letter and a survey form was mailed to these facilities. Facilities should complete and return the survey form to the DAQ Regional Offices, by mail or e-mail (preferred), no later thanAugust 31, 2012.
DAQ Permit Conditions and Regulatory Guides The DAQ has developed specific permit conditions and regulatory guides to assist NC facilities understand their compliance obligations with respect to emission standards, compliance monitoring, record keeping, and reporting requirements contained in the rule. The regulatory guides are intended for Title V and non-Title V facilities that are operating an air emission source(s) that is subject to the RICE NESHAP. The source could be listed on the permit or exempted from permitting requirements (i.e., listed on the "Insignificant / Exempt Activities" table attached to the air permit).

EPA Information and Guidance EPA has developed a regulation navigation tool that will help you understand the requirements for demonstrating compliance with the federal standard(s). |
| Federal Standard | Subpart | Applicability |
