ST. LOUIS, June 9, 2014 -- Arch Coal, Inc. (NYSE:ACI) issued the following statement as a follow-up to the U.S. Environmental Protection Agency's proposed greenhouse gas regulations announced on June 2:

"After analyzing EPA's 645-page proposal and supporting technical documents, it is increasingly evident that the Administration's plan for regulating greenhouse gases would place the U.S. economy at serious risk," said Arch Coal Senior Vice President of Strategy and Public Policy Deck S. Slone.

"As was demonstrated this past winter, the U.S. power grid is already in a precarious state due to regulation-driven power plant retirements that are just now getting under way.  In January and February, energy prices spiked in many regions and blackouts were avoided by the slimmest of margins.

"Despite these obvious stresses – and the very real costs they are imposing on U.S. consumers – the Administration has proposed another round of regulations that would drive still more plant closures.  Most surprising is the fact that the Administration would be willing to pursue such costly regulations without the potential for any discernible impact on greenhouse gas concentrations in the atmosphere.

"Fortunately, the ultimate authority for addressing greenhouse gas regulations under the relevant provision of the Clean Air Act rests with the states.  Many state legislatures and attorneys general have already spoken out in opposition to any plan that threatens to drive up consumer energy costs and force premature power plant closures.  The EPA-proposed caps are remarkably punitive for many states – particularly those that house America's manufacturing base.  We and many others will continue to encourage the states to stand their ground against EPA's efforts to impose a costly new program that goes far beyond what the law allows.

"America cannot shrink its way to a low-carbon future, nor can we address global climate concerns unilaterally.  The fact is that fossil fuels are virtually certain to remain the primary fuel source for world energy needs through at least mid-century.

"We strongly encourage the Administration to reconsider its regulatory approach and to focus instead on robust investment in advanced technologies, including carbon capture, utilization and storage.  That is the rational way forward for addressing climate concerns."
