Maine DEP Amends Its Air Licensing Regulations

Recently, the Maine DEP adopted amendments to its air licensing regulations, including Chapter 100, Definitions; Chapter 115, Major and Minor Source Air Emission License Regulations; and Chapter 140, Part 70 Air Emission License Regulations.  The amendments became effective December 1, 2012. 

The primary purpose of the amendments is to implement the federal New Source Review (NSR) program for fine particulate matter (a.k.a. PM2.5).  However, the amendments included a number of other important changes that should be considered by facilities filing applications for minor or major NSR licenses under Chapter 115 or applications for renewal or amendment of Chapter 140/Title V air licenses.
