      <abstract>The Office of Environmental Health Hazard Assessment (OEHHA), on behalf of the California Environmental Protection Agency (CalEPA), announces the availability of the Communities Environmental Health Screening Tool: CalEnviroScreen Version 4.0. CalEnviroScreen is a screening methodology that can be used to help identify California communities that are disproportionately burdened by multiple sources of pollution. The 4.0 report and supporting documents are available at: http://oehha.ca.gov/calenviroscreen/report/calenviroscreen-40</abstract>
      <purpose>This file contains data used in the latest iteration of the California Communities Environmental Health Screening Tool (CalEnviroScreen 4.0)</purpose>
