The Department of Environmental Protection will conduct a public hearing on proposed amendments to Chapter 115, Major and Minor Source Air Emission License Regulation, and Chapter 149, General Permit for Nonmetallic Mineral Processing Plants. The Department is proposing a new rule that allows most nonmetallic mineral processing plants, defined as any combination of a rock crusher and stationary engine functioning in conjunction, to obtain a permit from the Department without going through the licensing process currently required by Chapter 115. The hearing will be held May 27, 2008. http://www.maine.gov/sos/cec/rules/notices/2008/042308.htm.
