Sampling Design
•To develop a sampling design or monitoring plan, the following should be considered:
–Monitoring objectives, including consideration of geophysical setting, meteorology, types and characteristics of sources, and existing monitoring programs.
–Data quality objectives needed to answer questions to be asked of the data (i.e., how precisely or accurately do the questions need to be answered?).
–Options for what, when, where, how frequently, and for how long to monitor; these are related to the selection of appropriate monitoring equipment and laboratory analyses. 
–Data quality assurance and validation approach, including collocated data requirements, QA programs for analytical laboratories, and data validation guidelines for ambient data.
–Options for data analysis and exploration, including available tools, data analyses, data needs, and training needs.
