Proposed Indicators for the U.S. EPA's 2006 Report on the Environment (also called Proposed Indicators - EPA ROE 2006)

Due to the shortness of the review period and the volume of material released by EPA, API and its members have not had time to review every proposed indicator in detail. Our members have focused their review in areas where they have expertise, and have generated the comments discussed in the remainder of this letter. Our attached comments address: ?Presentation of nitrogen oxides (NOx) emissions trends; ?Measurement of greenhouse gas emissions; ?Use of National Emissions Inventory (NEI) information for various indicators for outdoor air quality; ?Problems with the proposed air toxics emission indicator; ?Selection of the benzene indicator and its limitations; ?Additional context and data for the VOC emissions indicator; ?Omissions in discussion of the ambient ozone indicator; ?Flaws in the indicator for toxic chemicals in wastes; ?Choice of the indicators for ?health status? and ?human disease and conditions,? and specific problems with some of these indicators; and ?Indicators for ?biomeasures of exposure.?
