Air Monitoring Public Comment Meeting Scheduled for Mason City

Posted October 22, 2002

DES MOINES - The DNR will hold a public comment meeting Oct. 23 in Mason City to seek input on draft rules that establish technical air monitoring techniques for hydrogen sulfide and ammonia.

The draft rules establish an Ambient Air Sampling Manual containing monitor siting requirements, data handling procedures, approved monitoring methods, and equipment and quality assurance requirements for determining compliance with proposed hydrogen sulfide and ammonia standards.

The meeting begins at 7 p.m. at the North Iowa Area Community College Muse-Norris Center, 500 College Drive in Mason City.

The proposal was established with input from a technical advisory group consisting of stakeholders and experts in air monitoring instruments and methods. There was consensus that the proposed measurement methods represent the best currently available monitoring methods.

An earlier September meeting in Mason City sought public comment on draft rules for the actual hydrogen sulfide and ammonia air standards. The public can still comment on either draft rules. The rules are posted at www.iowacleanair.com.

Written comments can be sent to Bryan Bunton, DNR Air Quality Bureau, 7900 Hickman Road, Suite 1, Urbandale, IA 50322 or bryan.bunton@dnr.iowa.gov or faxed to 515-242-5094. Comments will be accepted between September 18 and November 6, 2002.
