The US Environmental Protection Agency (EPA) has finalized the new Cross-State Air Pollution Rule (CSAPR) (also called the Transport Rule). The Cross-State Air Pollution Rule replaces and strengthens the requirements of the 2005 Clean Air Interstate Rule (CAIR), which the US Court of Appeals for the DC Circuit ordered EPA to revise in 2008. (The court allowed CAIR to remain in place temporarily while EPA worked to finalize the replacement rule.)
Carried long distances across the country by wind and weather, power plant emissions of sulfur dioxide (SO2) and nitrogen oxide (NOx) continually travel across state lines. The rule will improve air quality by cutting SO2 and NOx emissions that contribute to pollution problems in other states. By 2014, the rule and other state and EPA actions will reduce SO2 emissions by 73% from 2005 levels. NOx emissions will drop by 54%.

The CSAPR includes separate requirements for annual SO2 reductions; annual NOx reductions; and ozone-season NOx reductions. The rule defines upwind state obligations to reduce pollution significantly contributing to downwind nonattainment and maintenance areas based on:
- the magnitude of a state’s contribution;
- the cost of controlling pollution from various sources; and
- the air quality impacts of reductions.
Once EPA determined these obligations, including the amount of necessary pollution reductions, it set state budgets accordingly, with variability limits to assure that each state will meet its pollution control obligations.
The rule allows air quality-assured allowance trading among power plants, utilizing an allowance market infrastructure based on existing, successful allowance trading programs.

Under the rule, 27 states in the eastern half of the country will work with power plants to cut air pollution, which leverages widely available, proven and cost-effective control technologies. EPA will work with states to help develop the most appropriate path forward to deliver significant reductions in harmful emissions while minimizing costs for utilities and consumers.
The rule will protect over 240 million Americans living in the eastern half of the country, resulting in up to $280 billion in annual benefits, EPA says. The benefits outweigh the $800 million projected to be spent annually on this rule in 2014 and the roughly $1.6 billion per year in capital investments already underway as a result of CAIR.
In a supplemental rulemaking based on further review and analysis of air quality information, EPA is also proposing to require sources in Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin to reduce NOx emissions during the summertime ozone season. The proposal would increase the total number of states covered by the rule from 27 to 28. Five of these six states are covered for other pollutants under the rule. The proposal is open for public review and comment for 45 days after publication in the Federal Register.

A D - First, psycho, learn proper grammar.
Second, if you're going to comment, try to keep it focused on the article's content, instead of your paranoid ramblings.
Third, as SJC put it so quaintly, "Go away, NOW."
You turd-monkey...
