See EPA’s About PDF page to learn more.EPA's Environmental Modeling (E-Mod) Community of Practice (CoP) works with partners within and outside EPA. E-Mod identifies needs related to education and communication, providing access to literature impacting modeling. The EPA modeling CoP works to improve on existing guidance. As scientific issues evolve new guidance is developed to expand, but not necessarily supersede, the prior documentation needed in the past. The timeline below is to help users follow and understand the development of guidance documents by EPA staff.

• Environmental Modeling Guidance Documents and White Papers developed by the Council on Regulatory Environmental Modeling and the E-Mod
• Environmental Modeling Reports from the Science Advisory Board
• Modeling Guidance and Publications developed by other EPA organizations
