The Department of Environmental Protection will hold two public hearings on proposed amendments to 310 CMR 7.02, Plan Approval and Emission Limitations, and 310 CMR 7.03, Plan Approval Exemption: Construction Requirements. The amendments would include a simplified procedure whereby owners/operators of facilities with existing air plan approvals can make administrative amendments to those approvals, increase the threshold for a Non-Major Comprehensive Plan Application, allow owner/operators with multiple existing plan approvals to consolidate those approvals into a single document, elaborate on the emission control requirements for plan approval (specifically Best Available Control Technology), and include a new performance standard for rock crushing and materials handling equipment. The hearings will be held October 7 and 8, 2008. Comments are due October 20, 2008. http://www.mass.gov/dep/service/regulations/newregs.htm#airps.
