As the result of a recently released court order, the EPA has just completed its review of all national ambient air quality standards (NAAQS) for carbon monoxide (CO).

Upon conclusion of its review, the EPA found that all present primary standards remain essential at this time; each of the standards have been determined to positively impact the overall health and well-being of the general public.

As the EPA prepares for the future and continuously strives to protect public health, it has also concluded that no other secondary standard will need to be developed for CO anytime soon.

At the same time, the EPA is also considering the implementation of changes to the NAAQS for CO in the near future; for example, network design, as well as aspects of the Federal reference method, may be modified.

The final rule regarding the NAAQS for CO will be effective on Oct. 31, 2011.
