CalEnviroScreen 3.0 Draft

CalEnviroScreen has been updated: CalEnviroScreen 3.0 is available here.

The Office of Environmental Health Hazard Assessment (OEHHA), on behalf of the California Environmental Protection Agency (CalEPA), announces the availability of the draft of the latest version of the California Communities Environmental Health Screening Tool: CalEnviroScreen 3.0.

CalEnviroScreen is a screening methodology that can be used to help identify California communities that are disproportionately burdened by multiple sources of pollution. This draft updates CalEnviroScreen 2.0 in a variety of ways. The updates are described in more detail in the Proposed Changes document below. 
Major changes in the draft include:

  • More recent data for all indicators.
  • Improvements in the way some indicators are calculated to better reflect environmental conditions or population vulnerability to pollution.
  • The addition of two new indicators reflecting health and socioeconomic vulnerability to pollution.
  • Additional information on pollution along the California-Mexico border.

OEHHA held a series of webinars and workshops for the public to learn about the updates and provide public comment on the draft. The public comment period closed on October 21, 2016.
Public comments and workshop summaries can be viewed here.
