EPA Advisors Question EPA Data Limits In New Ozone NAAQS Review

摘要

EPA's science advisors evaluating the agency's new review for the national ambient air quality standard (NAAQS) for ozone are questioning the agency's plan to restrict consideration of older scientific studies from being included in the review.rnThe advisors say excluding work that was done to support the contested 2008 ozone NAAQS will handicap the current effort. However, industry supports the restrictions, saying the panel's wish to use the older studies may be driven by a desire to impose a more stringent standard than the 2008 limit of 75 parts per billion (ppb), which EPA is now reconsidering.
