The California Environmental Protection Agency (Cal/EPA) along with the Office of Environmental Health Hazard Assessment (OEHHA) have released the California Communities Environmental Health Screening Tool, Version 1 (CalEnviroScreen 1.0). The agencies had previously released two drafts for CalEnviroScreen last summer and most recently at the beginning of this year. Some of the comments received on the first two drafts were used to improve the tool. The tool provides the state the ability to comprehensively screen the state and determine which communities are most burdened by multiple sources of pollution. It also presents statewide results of the analysis using the screening tool. To visually illustrate the results, there is an online map that shows the zip codes burdened with the highest pollution impact to lowest impact, certain to cause concern by residents in those high impact zip codes.
