## MANE-VU

Reducing Regional Haze for Improved Visibility and Health STATEMENT OF THE MID-ATLANTICINORTHEAST VISIBILITY UNION (MANE-VU) CONCERNING A COURSE OF ACTION WITHIN MANE-VU TOWARD ASSURING REASONABLE PROGRESS The federal Clean Air Act and Regional Haze rule require States that are reasonably anticipated to cause or contribute to impairment of visibility in mandatory Class I Federal areas to implement reasonable measures to reduce visibility impairment within the national parks and wilderness areas designated as mandatory Class I Federal areas. Most pollutants that affect visibility also cause unhealthy concentrations ofozone and fine particles. In order to assure protection ofpublic health and the environment, any additional air pollutant emission reduction measures necessary to meet the 2018 reasonable progress goal for regional haze should be implemented as soon as practicable
. To address the impact on mandatory Class I Federal areas within the MANEVU region, the Mid-Atlantic and Northeast States will pursue a coordinated course ofaction designed to assure reasonable progress toward preventing any future, and remedying any existing impairment ofvisibility in mandatory Class I Federal areas and to leverage the multi-pollutant benefits that such measures may provide for the protection of public health and the environment. This course of action includes pursuing the adoption and implementation of the following "emission management" strategies, as appropriate and necessary:
• timely implementation ofBART requirements; and
• a low sulfur fuel oil strategy in the inner zone States (New Jersey, New York, Delaware and Pennsylvania, or portions thereof) to reduce the sulfur content of: distillate oil to 0.05% sulfur by weight (500 ppm) by no later than 2012, of#4 residual oil to 0.25% sulfur by weight by no later than 2012, of#6 residual oil to 0.3

- 0.5% sulfur by weight by no later than 2012, and to further reduce the sulfur content ofdistillate oil to 15 ppm by 2016; and

• a low sulfur fuel oil strategy in the outer zone States (the remainder of the MANE-VU region) to reduce the sulfur content ofdistillate oil to 0.05% sulfur byweight (500 ppm) by no later than 2014, of#4 residual oil to 0.25

- 0.5% sulfur by weight by no later than 2018, and of#6 residual oil to no greater than 0.5 % sulfur byweight byno later than 444 North Capitol Street, NW - Suite 638 - Washington , DC 20001 202.508.3840 P - 202
.508.3841 f www.mane- vu.org2018, and to further reduce the sulfur content ofdistillate oil to 15 ppm by 2018, depending on supply availability; and

• A 90% or greater reduction in sulfur dioxide (S02) emissions from each ofthe electric generating unit (EGU) stacks identified by MANE-VU (Attachment 1- comprising a total of 167 stacks

- dated June 20, 2007) as reasonably anticipated to cause or contribute to impairment ofvisibility in each mandatory Class I Federal area in the MANE-VU region
. Ifit is infeasible to achieve that level ofreduction from a unit, alternative measures will be pursued in such State; and

• continued evaluation ofother control measures including energy efficiency, alternative clean fuels, and other measures to reduce S02 and nitrogen oxide (NOx) emissions from all coal-burning facilities by 2018 and new source perform::lnce standards for wood combustion. These measures and other measures identified will be evaluated during the consultation process to determine ifthey are reasonable and cost-effective. This long-term strategy to reduce and prevent regional haze will allow each state up to 10 years to pursue adoption and implementation ofreasonable and cost-effective NOx and S02control measures. Adopted by the MANE-VU States and Tribes on
