types and sources of interest, obtaining and/or developing the necessary input data, and running the appropriate models and/or methodologies. 

Step 4: Coordination/Review and Documentation of Results – Once the air quality assessment has been conducted, the purpose of this step is to coordinate and review the analysis with the appropriate agency and to address any comments prior to moving forward with the project/action. Upon completing the coordination/review process, the final step is to properly document the results. As described in Section 4.1.4 (Step 4: Document the Results), this work entails reporting the assessment findings in narrative and other formats that are appropriate, informative and easy to understand to reviewing agencies and the general public. 

Within these four basic steps of the air quality assessment process, there are a number of sub - steps or activities that are typically necessary. The remainder of this Handbook section describes the sub-steps to each of the four basic steps.
