Public Input Opportunity: DNR Draft Proposal to Adopt NESHAP and NSPS
Posted: 11/18/2013

The Iowa DNR Air Quality Bureau (DNR) invites the public to provide informal comments on a draft rulemaking proposal. The DNR is considering adopting federal standards for several different industries and operations, including utility boilers, industrial, commercial and institutional boilers, solid waste incinerators, process heaters, cement plants, and stationary engines.


This informal comment period is an opportunity for stakeholders to assist the DNR in developing the rule proposal. After considering public input, the DNR will determine whether to proceed with the rule making and present a proposal to the Environmental Protection Commission (EPC). The public may also provide comments on the proposal at the EPC meeting. If the EPC approves the proposal for public comment, the Notice of Intended Action will be published in the Iowa Administrative Bulletin. The Notice’s publication will initiate a formal public comment period of at least 30 days. The DNR will hold a public hearing during the public comment period.



The DNR has prepared a draft proposal to adopt recent federal revisions to air toxics standards (called National Emission Standards for Hazardous Air Pollutants or “NESHAP”) and new source performance standards (NSPS). The DNR proposes to adopt the standards by reference into state rules so that all compliance deadlines will be according to federal timelines. Concurrent with adopting the federal standards for utility boilers, the DNR is proposing to add a sunset date for the state’s current mercury emissions monitoring requirements.


The draft rulemaking proposal includes rescission of previously adopted NESHAP and NSPS for mineral and material processing. Iowa has never had any affected sources for these standards, and it is highly unlikely that these industries would locate in Iowa.


Facilities are subject to the federal standards regardless of whether the standards are adopted into Iowa’s rules. However, by adopting these standards, the DNR can provide compliance assistance and outreach to affected facilities as soon as possible.
