The Air Pollution Control Board seeks public comment on proposed changes to 326 Ind. Admin. Code 4.1, concerning open burning. Changes would add types of burning allowed under the regulation, including burning for natural area and wildlife habitat maintenance and the burning of clean petroleum products for fire training. According to the public notice, the exemptions are not expected to increase the amount of open burning occurring in the state. There will be a public hearing on May 4, 2011. http://www.in.gov/legislative/iac/20110216-IR-326090362SNA.xml.pdf for the proposed changes. http://www.in.gov/legislative/iac/20110216-IR-326090362PHA.xml.pdf for the public notice
