The Clean Air Act requires states to consider four factors to determine which emission control measures are needed to make reasonable progress in improving visibility: 1) costs of compliance, 2) time necessary for compliance, 3) energy and non-air quality environmental impacts of compliance, and 4) remaining useful life of any existing source subject to such requirements. The plan must include reasonable measures and identify the visibility improvement that will result from those measures (i.e., the reasonable progress goal).

2007 Analysis

MARAMA prepared information to help the states consider the four factors listed above with respect to key emissions sources identified by the states. This website provides copies of the following relevant documents: work products from the Reasonable Progress Goals Project and summaries of meetings and conference calls between the state, tribal, and federal organizations.

Based on available information, the MANE-VU Reasonable Progress Workgroup selected the following source categories for analysis:

• Coal and oil-fired Electric Generating Units, (EGUs);

• Point and area source industrial, commercial and institutional boilers;

• Cement kilns;

• Lime kilns;

• The use of heating oil; and

• Residential wood combustion and open burning.

For more information about this analysis, please see the Reasonable Progress Analysis section of the MARAMA website.

June 2007 MANE-VU Statements on Controls

MANE-VU met on June 7, 2007 in Providence, Rhode Island, and the following statements and Class I States' resolutions were adopted to describe a coordinated approach for pursuing the adoption and implementation of measures to reduce regional haze.  These statements are often referred to as the "MANE-VU Ask."  MANE-VU itself does not have regulatory authority, and adoption and implementation on any of these measures would require follow-up actions by MANE-VU states, states outside MANE-VU, and the U.S. Environmental Protection Agency.
