LCG, April 10, 2026--The U.S. Environmental Protection Agency (EPA) announced yesterday a rule proposing several revisions to the federal regulations governing the disposal of coal combustion residuals (CCR) and the beneficial use of CCR. 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.

Construction Halted on SWEPCO's Coal-fired Power Project
LCG, December 3, 2008--Construction at Southwestern Electric Power Company's (SWEPCO) coal-fired electric generating facility in southwest Arkansas yesterday was halted in response to an appeal filed by the Sierra Club and Audubon Arkansas with the Arkansas Pollution Control and Ecology Commission. According to a SWEPCO spokesperson, the halt in construction work is required when an appeal is filed. SWEPCO plans to request that construction be allowed to continue pending the decision regarding the appeal.
Following a two-year review of the application, the Arkansas Department of Environmental Quality issued the air permit for the proposed John W. Turk Jr. plant on November 5, 2008.
SWEPCO, a subsidiary of American Electric Power (AEP), proposed to construct the 600-MW plant in Hempstead County, Arkansas to serve retail and wholesale customers in Arkansas, Texas and Louisiana. The estimated cost of the facility is $1.52 billion. The proposed facility will use ultra-supercritical technology and will burn sub-bituminous, Powder River Basin (PRB) coal from Wyoming.
In a 2-1 decision last November, the Arkansas Public Service Commission (APSC) granted a Certificate of Environmental Compatibility and Public Need (CECPN) to construct the plant.
In March 2008, the Louisiana Public Service Commission (LPSC) unanimously approved SWEPCO's request to build the plant, including a requirement for SWEPCO to prepare and submit a study that identifies potential, cost-effective energy efficiency and load management programs for SWEPCO's Louisiana customers. The Public Utility Commission of Texas approved the proposal in July 2008, rejecting a recommendation from an administrative law judge (ALJ).
