EPA considers standard for airborne fine particles

Article Abstract:

The EPA is reviewing a proposal to impose a new 2.5 microns-and-smaller standard for fine particle pollution and to ease existing 24-hour standards for coarse particulates. The proposal, which was drafted by EPA staff, has been criticized not only by many outside scientists but by the EPA Science Advisory Board's Clean Air Scientific Advisory Committee as well. Observers believe that widespread opposition will prevent the agency from meeting the court-imposed Jan. 1997 deadline for new air quality standards for particulate matter.

EPA particulate matter health effects document criticized

Article Abstract:

The Clean Air Scientific Advisory Committee censured the EPA's draft document on Air Quality Criteria for Particulate Matter because it failed to present convincing linkages on the relationship between particulate matter and mortality and/or morbidity. The agency's review echoed the sentiments of other researchers who conducted their own investigations about the health effects of particulate matter. The panel believes time constraints and not incompetency were responsible for the deficiencies in the document.

A new formula for fighting urban ozone

Article Abstract:

The EPA will require metropolitan areas with severe ozone problems to sell only the new reformulated gasoline (RFG) beginning in 1995 to cut the amount of toxic air pollutants from vehicles and to reduce urban ozone levels. The RFC requirement is in line with the many provisions of the Clean Air Act Amendments of 1990, which envisions a 15% cut in ozone-forming volatile organic compound emissions and a similar reduction in air toxics.
