The EPA designed the rule to encourage resource recovery, allow for site-specific considerations in permitting, and provide regulatory relief while continuing to protect human health and the environment. The EPA will be accepting comments on the rule for 60 days after publication in the Federal Register, and it will also hold an online public hearing on the rule.

Black Hills Power Applies to Decommission Coal Plants
LCG, September 17, 2013--The Wyoming Public Service Commission recently published a public notice stating that Black Hills Power filed an application on August 29, 2013 with the Commission to retire three aging coal units. The company stated the decision to decommission the facilities is driven by costs to comply with ever-growing regulations dictated by U.S. Environmental Protection Agency (EPA).
The Commission's public notice stated, "After an analysis of the cost of compliance, as well as consideration of the likelihood of additional future EPA regulations affecting the continued operation of the facilities, Black Hills Power determined the most cost effective plan for EPA compliance is to retire and decommission the facilities."
The coal-fired units targeted for retirement are the 34.5-MW Osage unit in Osage, Wyoming and the 21.8-MW Neil Simpson I unit in Gillette, Wyoming. In addition, the 25-MW Ben French unit in Rapid City, South Dakota is targeted. The newest of the three units is Neil Simpson I, which commenced commercial operations in 1969. All three units are owned entirely by Black Hills Power.
According to the public notice, Black Hills Power states the EPA issued the National Emission Standards for Hazardous Air Pollutants for Area Sources: Industrial, Commercial and Institutional Boilers (Area Source Rules), to reduce emissions of hazardous air pollutants from various small boilers, to include coal-fired units of 25 MW or less. The deadline for compliance with the Area Source Rules is March 21, 2014.
