"Hot Spots" Public Notification
This page last reviewed July 1, 2012
Assembly Bill (AB) 2588 (Connelly), the Air Toxics "Hot Spots"
Information and Assessment Act, requires facilities found
to have a significant risk from their emissions to
notify all exposed persons. Once risk assessments (see
are reviewed by the Office of Environmental Health Hazard
Assessment (OEHHA) and approved by the air pollution control or
air quality management district (district), facility
operators must notify all exposed persons of the risk assessment
results if the district determines that there is a potentially
significant health risk associated with emissions from
the facility. Each district is responsible for establishing the
notification threshold at which facilities are required to notify all
exposed persons with either a
letter to individual neighbors, or with a
newspaper notification. Some
districts also require the facility to post information about the
facility risk at the local library.
The California Air Pollution Control Officers Association (CAPCOA) Toxics Committee, in cooperation with OEHHA and the Air Resources Board (ARB), developed the CAPCOA Public Notification Guidelines, October 1992. The purpose of these guidelines is to assist districts in developing their public notification procedures. However, districts may develop and use notification methods which differ from the CAPCOA guidelines.

Some facilities with diesel engines may have to conduct public notification. An industrywide or standard public notice for diesel PM may be appropriate, depending on district policies.
