Amnesty (Subpart ZZZZ) & Requirements for Stationary Internal Combustion Engines (Subpart IIII, JJJJ & ZZZZ)

Iowa DNR assumes responsibility for RICE NESHAP

The Iowa Department of Natural Resources (DNR) adoption of the 2010 and 2013 RICE NESHAP amendments became effective today, October 23, 2013.  This means that DNR, rather than EPA, is now the primary authority for RICE implementation in Iowa. RICE NESHAP is the acronym for National Emission Standards for Hazardous Air Pollutants (NESHAP) for Stationary Reciprocating Internal Combustion Engines (RICE) (40 Code of Federal Regulations (CFR) Part 63, Subpart ZZZZ).

 

DNR has posted a document on the Air Toxics-NESHAP page that explains how the transfer of responsibilities from EPA to DNR and to the Polk and Linn County air agencies is being handled. The document addresses logistical questions such as where RICE notifications and reports should be sent, and which agency will review stack testing being conducted in late 2013.

 

Compliance assistance tools posted on DNR’s website

DNR has also created several compliance assistance tools for facilities subject to the RICE NESHAP.  These tools, along with information about other regulations that affect engines, are posted on the DNR Air Toxics-NESHAP website or at http://www.iowadnr.gov/InsideDNR/RegulatoryAir/AirToxics-NESHAP.aspx - scroll down to “Reciprocating Internal Combustion Engines (RICE)”. Notification forms and a summary table of the RICE NESHAP requirements are posted on DNR’s website as well. Direct links are listed below for your convenience:

 

Construction permit amnesty for engines

The DNR and Polk and Linn County air agencies want to assist facilities in complying with all applicable regulations, including air quality construction permit requirements. For facilities that do not have the required permits for engines that have been installed or modified, or that have not submitted required permit-related notifications or registrations, the DNR and Polk and Linn County air agencies are providing an opportunity to comply with these requirements without enforcement actions and penalties. Details about the amnesty and engine permitting requirements can be found here.

Requirements for Stationary Internal Combustion Engines

All owners or operators of a stationary internal combustion engine meeting the applicability criteria as outlined in Subpart IIII or Subpart JJJJ must submit a construction permit to Polk County - AQD.  The manufacturer's nameplate rated capacity at full load shall be defined as the brake horsepower output at the shaft.  All engines with a BHP ≥ 100 must submit a construction permit application.

If a facility determines it does not have the required permit for an engine, a complete construction permit application and notification must be submitted.

 Stationary Internal Combustion Engine Initial Notification

 

Several regulations have expanded the number and type of stationary RICE that must comply with federal requirements. These include:

  • New Source Performance Standards (NSPS) - Standards of Performance for Stationary Spark Ignition Internal Combustion Engines (40 CFR Part 60 Subpart JJJJ - Scroll to reach the Subpart.) – "the Spark Ignition NSPS rule"
  • Standards of Performance for Stationary Compression Ignition Internal Combustion Engines (40 CFR Part 60 Subpart IIII - Scroll to reach the Subpart.) – "the Compression Ignition NSPS rule"
