EPA Air Chief Highlights Major Research Barriers To Multipollutant Rules

摘要

EPA air chief Regina McCarthy says there are major gaps in research data - including how to better assess different mixtures of pollutants - that the agency must fill before it can achieve its oft-stated goal of pursuing a multipollutant approach to regulation, under which EPA develops rules to cut emissions of several pollutants at once.rnMcCarthy told the annual Health Effects Institute (HEI) conference in Alexandria, VA, April 26 that while a multipollutant strategy is essential to efficient and effective regulation, the agency still lacks much of the information it needs to implement the idea. EPA is already wrestling internally over how to define multipollutant regulation, and how to pursue the necessary research to support whatever approach it settles on.
