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.

Arizona Public Service To Contest Treatment of Construction Costs
LCG, Aug. 28, 2002--Following a decision by the Arizona Corporation Commission (ACC) that Arizona Public Service (APS) will not be required to divest generation assets, the largest utility in Arizona will seek to insure recovery of costs expended on recent plant construction.The Arizona Corporation Commission, which is much like other states' public utility commissions, removed the provision concerning divestiture that had been part of state restructuring legislation enacted in 1999. APS's regulated unit has not been allowed to build plants, although five generating units were built by the deregulated affiliate Pinnacle West Energy to guarantee reliability. Pinnacle West and APS are subsidiaries of the Pinnacle West Capital Corporation.The ACC's decision to no longer require divestiture by APS was part of a broader ruling that recognized the decreasing likelihood that deregulation of the retail power market will take place in Arizona. "While we understand the comlexity of issues facing the ACC, we are hopeful that when all factors are considered, the Commissioners will reassess their decision and consider the negative imact it will have on the treatment of these assets," the chairman and CEO of APS and Pinnacle West Capital Corporation, Bill Post, said. Eight power plants were to be transferred from APS to Pinnacle West Energy. Five generating units at the Redhawk, West Phoenix and Saguaro plants have been built by the deregulated affiliate.
