The IDNR adopted 40 CFR 63, Subpart ZZZZ National Emission Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines (commonly known as the RICE NESHAP) on October 23, 2013. The IDNR, Polk County, and Linn County are now responsible for enforcing RICE NESHAP compliance in Iowa instead of the U.S. EPA. IDNR has developed a document outlining the transition of authority from the U.S. EPA to the Iowa regulatory agencies. IDNR posted optional forms for completing the Notification of Compliance Status, Semi-Annual Compliance Report, and Annual Compliance Report required by the RICE NESHAP. Guidance for RICE NESHAP applicability is also provided.
*Note that IDNR has determined that emergency engines subject to maintenance requirements and non-emergency engines subject to emission limits under the RICE NESHAP are not eligible to use the SUE. If the SUE is being used for an engine that is no longer eligible because of the RICE NESHAP, and the engine does not qualify for another permit exemption, a construction permit must be obtained. Facilities should consider what other exemptions may be allowed.
IDNR, Polk County, and Linn County are providing an amnesty period for completing required registrations, notifications, and/or construction permit applications for engines. Facilities have until April 23, 2014 to comply with all submittal requirements without facing any enforcement actions, including penalties, for failure to submit notifications or obtain permits. This amnesty period does not include violations of the RICE NESHAP or Prevention of Significant Deterioration permitting requirements. Refer to the IDNR website for more information.
