Guidance on the Use of Models and

Other Analyses for Demonstrating

Attainment of Air Quality Goals for

Ozone, PM2.5, and Regional Haze

 

ACKNOWLEDGMENTS

We would like to acknowledge contributions from members of an external review group

and U.S. EPA Regional Office modeling staffs in providing detailed comments and suggestions

regarding the final version of this guidance. In particular, we would like to thank staff members

of the Lake Michigan Air Directors Consortium (LADCO), Carolina Environmental Program

(CEP), South Coast Air Quality Management District (SCAQMD), California Air Resources

Board (CARB), Texas Commission on Environmental Quality (TCEQ), North Carolina Division

of Air Quality (NCDAQ), New York State Department of Environmental Conservation

(NYSDEC), Georgia Environmental Protection Divsion (GAEPD) and Computer Sciences

Corporation (CSC) for testing our ideas for a modeled attainment test and sharing the results

with us.

We would also like to acknowledge the contributions and accomplishments of Ned

Meyer. Ned wrote the original drafts of the ozone and PM2.5 modeling guidance documents. He

also developed the relative attainment tests and put his vision on paper. The final version of this

guidance is shaped by Ned’s words and thoughts.
