EPA MT SIP rulings 3-10-10

March 10, 2010

From:  Don Allen, Executive Driector

To:  WETA Environmental/Regulatory Committee

Subject:  EPA Announces Montana SIP Approvals and Disapprovals

cc: WETA Board of Directors

Attached is a new EPA communication in which they list State Implementation Plan provisions that are approved, others not approved and others that are still in limbo, some of those at the request of the State. A quick read of the document reveals some issues that need more clarification, such as some of the definitions. DEQ’s Dave Klemp, who heads the Air Resources Bureau say they are beginning an analysis of EPA’s decisions and will want to discuss their conclusions with industry when they can complete their evaluation. This document is a good example of how the EPA has not been focused, with some of Montana’s SIP’s having been submitted over a decade ago.
