Environmental Protection Indicators for California (EPIC)

What is the EPIC project?
The Environmental Protection Indicators for California (EPIC) project is a collaborative effort of the California Environmental Protection Agency (CalEPA), the Resources Agency, the Department of Health Services, and an external advisory group consisting of representatives from business, public interest groups, academia, and local government. The project, led by CalEPA's Office of Environmental Health Hazard Assessment (OEHHA), is responsible for developing and maintaining "environmental indicators" for California.

What are environmental indicators, and why are they important?
Environmental indicators are measurements that track environmental conditions over time. In recent years, more and more states and localities in the United States, as well as countries and international organizations, have developed environmental indicator systems. Examples of environmental indicators include the level of air pollution, volume of solid and hazardous waste deposited in landfills, status of chinook salmon populations, and extent of forest acreage.
Environmental indicators improve our understanding of the environment and how human activities, along with other factors, can influence it. They can be used to gauge progress toward achieving goals to improve environmental quality and reduce threats to human health and natural ecosystems. Environmental indicators are also useful for communicating a great deal of complex information in a simple, concise format.

California has traditionally assessed the success of its environmental programs based on measures of activity, such as the number of permits granted, notices of violation issued, or regulatory standards adopted. Environmental indicators can illustrate the effects these activities have on the environment.

Past Efforts

What has the EPIC project accomplished?
Following its establishment in 2000, the EPIC project established a process for identifying and selecting environmental indicators. This process generated an initial set of 84 indicators dealing with air quality, water quality, water supply and use, waste management, human health, ecosystem health, pesticide, and transboundary issues.

Sufficient data have been collected for about half of the initial set of indicators to allow the project to assess trends in environmental conditions; these are designated as "Type I" indicators. The remainder either requires more data collection or analysis (Type II indicators) or requires the establishment of a data collection system (Type III indicators). Type II and Type III indicators identify new kinds of data that could improve our understanding of environmental conditions. In the future, policymakers will consider the collection and analysis of data from Type II and III indicators when planning their agencies' activities and programs. The chart below gives examples of each type of indicator.

 

Indicator Status
Examples of Indicators

I. Adequate data collected to assess trends

  • Number of days with unhealthy ozone, carbon monoxide, and/or particulate matter (PM10)
  • Number of coastal beaches posted or closed
  • Per capita amount of solid waste generation, diversion, and disposal
  • Number of hazardous materials spills and releases
  • Total reported occupational illnesses and injuries associated with pesticide exposure
  • Status of threatened and endangered species
  • Extent of change in range land and forest habitat
  • Air temperature


II. Further data collection or analysis needed to assess trends

  • Total emissions of toxic air contaminants (TACs)
  • Magnitude of groundwater contaminant plumes
  • Extent of cleanup of illegal solid waste disposal sites
  • Volume of hazardous waste imported or exported
  • Number of growers adopting reduced-risk pest management systems
  • Status of the northern spotted owl

III. No ongoing data collection

  • Extent of indoor exposure to formaldehyde
  • Number of environmental releases from active landfills
  • Levels of mercury in human blood and other tissues
  • Quantity of endocrine-disrupting chemicals in aquatic ecosystems

 

The project considered the need for indicators that produce information on specific regions of the state as well as indicators for issues such as sustainability, environmental justice, and pollution prevention.

The EPIC project held a conference in 2001 and published a report (and report summary) outlining its activities in 2002. The 2002 report was updated in 2004 and in 2005 was updated with an addendum.  A glossary of terms from the report is available for easy reference.  These products can assist state environmental agencies in developing agency policies, budgets, and strategic plans.

Current Efforts

OEHHA Climate Change Indicators of California 2013 header image

In an extension of the EPIC project, the Office of Environmental Health Hazard Assessment (OEHHA) has released documents on Indicators of Climate Change in California tracking the impacts of climate change in California.

"Indicators of Climate Change in California" is a report presenting 36 indicators tracking trends in atmospheric gases that influence climate, changes in the state's climate, and the impacts of climate change on California's environment and people. This report is an update to the first Indicators of Climate Change in California Report, which was released in 2009.  A workshop on Indicators of Climate Change in California was held in June of 2015 and the next report is due for completion in 2017.
