CalEnviroScreen is a science-based tool that identifies the California communities most burdened by pollution from multiple sources and most vulnerable to its effects. Los Angeles Workshop.

Developed by the Office of Environmental Health Hazard Assessment (OEHHA) at the request of CalEPA, CalEnviroScreen is a science-based tool that identifies the California communities most burdened by pollution from multiple sources and most vulnerable to its effects. The tool will be used to help implement a state law (SB 535) that requires that 25 percent of the proceeds from the state’s cap-and-trade auctions be invested in projects that benefit disadvantaged communities, including 10 percent for projects located within these areas.

OEHHA extended the public comment period for its Proposed Revised Reference Exposure Levels for Toluene Diisocyanate and Methylene Diphenyl Diisocyanate.

The tool uses data on 12 types of pollution and environmental factors and seven population characteristics and socioeconomic factors to create scores for each of the state’s 8,000 census tracts.

Overall CalEnviroScreen scores are calculated from the scores for two groups of indicators: Pollution Burden and Population Characteristics. This page shows the CalEnviroScreen Pollution Burden indicators. Pollution burden represents the potential exposures to pollutants and the adverse environmental conditions caused by pollution. Click on any one of the indicators below to get more information about that indicator.

Overall CalEnviroScreen scores are calculated from the scores for two groups of indicators: Pollution Burden and Population Characteristics. This page shows the Population Characteristics indicators, which represent biological traits, health status, or community characteristics that can result in increased vulnerability to pollution.

Proposal to amend Title 27, Cal. Code of Regulations, section 25903, Appendix A,1 to update the Proposition 65 summary that must be included as an attachment to all Notices of Violation that are served upon alleged violators of Proposition 65. This update would reconcile the regulation with the changes to Proposition 65 made in 2013 by the enactment of Assembly Bill 227 (Gatto, Chapter 581, Statutes of 2013).
