    The Environmental Protection Agency Dec. 13 published a final rule requiring 13 states to revise their state implementation plans to enable them to issue preconstruction permits for new and modified sources of greenhouse gas emissions. The requirements to revise the plans apply to all or part of Arizona, Arkansas, California, Connecticut, Florida, Idaho, Kansas, Kentucky, Nebraska, Nevada, Oregon, Texas, and Wyoming. EPA has set Jan. 2, 2011, as the date on which prevention of significant deterioration emission control and permitting requirements apply to greenhouse gas sources. According to EPA, the final rule, known as a SIP Call, will give states without adequate implementation plans enough time to take action to accept a federal implementation plan for PSD permitting of greenhouse gas emissions by Jan. 2, 2011. Most states will be able to implement PSD permitting for greenhouse gas emissions under their current state implementation plans. According to EPA, the 13 states affected by the final rule must change their laws and regulations, as well as their state implementation plans, to allow PSD permitting for greenhouse gases. For example, some of the states identify the pollutants covered by PSD permitting but do not include greenhouse gases.

Did you know…?
    PSD requires new and modified sources to control emissions using best available control technology, which is determined on a case-by-case basis at each facility and may be influenced by factors such as the economic, energy, and environmental impacts of alternative control strategies. While economic, energy, and environmental impacts must be considered in every case, the relative weight given to each factor may vary according to local conditions and preferences, the philosophies of EPA regional administrators, and the nature of the source. Any discussion of air pollution control technology involves descriptions of the equipment available and its application to specific industries. In general, add-on equipment falls into large categories: chemical scrubbers, condensers, fabric filters (baghouses), incinerators, precipitators, and wet scrubbing devices. Within these categories are many combined uses, refinements, subtypes, and specific industrial applications. Often they are used in combination with each other or with process changes and good operating practices. EPA emission standards do not require that specific equipment be used, though they may specify operating practices or describe the control device they consider necessary if a standard is to be met.
