| In 2007, a decision was made by the Air Quality Research Subcommittee of CENR and approved by the Director of CENR to redefine the scope of NAPAP in advance of the next report. Parts of previous NAPAP reports essentially duplicate what is already covered in annual progress reports issued by the Acid Rain Program Office of the U.S. Environmental Protection Agency (EPA). These EPA progress reports include annual data on emissions, air quality and deposition, market indicators (e.g. allowance prices), and health benefits, as well as information on the status of acid-sensitive lakes and streams as a result of implementation of Title IV. Future plans call for EPA to continue to issue these annual reports as a means of reporting progress on the Clean Air Interstate Rule (CAIR) and Clean Air Visibility Rule (CAVR), which are scheduled to take effect in 2009 and 2014, respectively. In light of these ongoing EPA reports, a decision was made that future NAPAP reports should focus on providing an integrated assessment of the effects of acid precipitation on sensitive ecosystems. |
