Air Toxics Standards for Stationary Engines

(40 CFR Part 63 Subpart ZZZZ, also known as RICE NESHAP)

Governor Terry Branstad issued Executive Order 72 rescinding Iowa’s rule adopting federal amendments to the Hazardous Air Pollutants standard for stationary Reciprocating Internal Combustion Engines (RICE NESHAP*), on April 4, 2011. The Governor emphasized support for protecting the health, safety and welfare of the people of the state of Iowa should be done effectively and efficiently without imposing unnecessary burdens that reduce jobs and hurt job growth. The RICE NESHAP was too costly for small utilities to maintain and operate rarely used emergency engines as required by the EPA, and that implementing the regulation would create a financial impact on utility customers.

As a result of the Governor’s action, Iowa DNR no longer has full delegated authority for the RICE NESHAP. The federal RICE NESHAP remains in effect and EPA is still implementing the standard. The federal compliance date for most existing stationary diesel engines of May 3, 2013, remains in effect under federal regulation.

The Iowa DNR will continue to answer general questions about this standard. However, the Iowa DNR no longer has authority to give a determination (decision) regarding applicability of the standard or compliance with the standard.

Because Iowa continues to have an obligation (under the state implementation plan and federal program delegations) to inform permittees of both federal and state regulatory requirements, the Iowa DNR plans to include a reference to the federal standard in air construction permits and Title V operating permits issued for engines that fall under the federally regulated source category.

The Iowa DNR recommends that Iowa facilities access the following EPA-developed online implementation tools and guidance:

To obtain information on whether a specific engine may be subject to the RICE NESHAP or whether it is in compliance with RICE NESHAP requirements, please contact EPA Region VII (contact is David Peter, e-mail Peter.David@epamail.epa.gov or call 913-551-7397). For other questions, please contact Christine Paulson at the DNR (e-mail Christine.Paulson@dnr.iowa.gov or call 515-242-5154).

* RICE NESHAP is the commonly-used acronym for the 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]
