California Proposes Methodology to Evaluate Impacts of Pollution on
LOS ANGELES—California regulators unveiled a proposed methodology July
30 for evaluating the cumulative impacts of multiple sources of
pollution on communities.
Called the California Communities Environmental Health Screening Tool
(CalEnviroScreen), the draft methodology employs existing environmental,
health, and socioeconomic data to identify areas of the state most
vulnerable to cumulative impacts of air pollution, pesticides,
contaminated water, waste sites, and other types of pollution.
State and local officials can use the screening tool, once it is
finalized, to prioritize cleanup and abatement projects and direct
grants and other resources to communities with the greatest needs, the
California Environmental Protection Agency said in a written statement.
“The draft screening tool is meant to present a broad picture of the
burdens and vulnerabilities different areas face from environmental
pollutants,’’ said George Alexeeff, director of Cal/EPA's Office of
Environmental Health Hazard Assessment (OEHHA).
Chemical-by-chemical, source-by-source, route-by-route risk assessment
approaches are not well-suited to assess community-scale impacts,
according to OEHHA. The agency said it has developed “a workable
approach’’ that can incorporate multiple factors to reflect community
impacts not included in traditional risk assessments.
‘A Work in Progress.'
OEHHA called the draft document “a work in progress.’’ The proposed
methodology is not designed to precisely predict or quantify specific
health risks or even the effects associated with cumulative exposures
for a given community or individual, the agency said. Also, it does not
directly correlate the potential impacts of exposure from different
types of pollutants, like particulate exposures from vehicle emissions
and exposures from pesticides or hazardous materials.
CalEnviroScreen is part of an effort to implement a statewide
environmental justice plan, officials said.
“Our objective is to provide state and local decision makers with
information that will enable them to focus their time, resources, and
programs on those portions of the state that are most in need of
assistance,’’ Cal/EPA Secretary Matt Rodriquez said in a written statement.
Cal/EPA's Cumulative Impacts and Precautionary Approaches Work Group
will review the proposal at its Aug. 7 meeting in Sacramento.
Five public workshops are planned to discuss the proposed
methodology—Aug. 21 in Los Angeles; Aug. 22 in San Bernardino; Aug. 23
in San Diego; Sept. 5 in Fresno; and Sept. 6 in Oakland. Public comments
on the proposal are due Sept. 18.
Cal-EPA also is seeking peer-review of the document.
