Air toxics have been steadily decreasing in California since 1990 due to on-going regulatory developments.  The California Legislature adopted the Air Toxics Hot Spots Information and Assessment Act of 1987.  This law established a statewide inventory program for air toxic emissions from individual facilities as well as requirements for risk assessment and public notification.  As a result of the act, local air districts have been implementing Air Toxics Hot Spots compliance programs, facilities have been installing control equipment, and the California Air Resources Board has been adopting mobile emission controls for new vehicles.  The Office of Environmental Health Hazards Assessment (OEHHA) updated its methods for air toxic assessments through its February 2015 Air Toxics Hot Spots Program Guidance Manual for Preparation of Health Risk Assessments update (available here).  Due to these changes, many air districts have recently revised their health risk thresholds for air permits and California Environmental Quality Act (CEQA) projects.

In response to changes in air toxic assessment methods, the California Air Pollution Control Officers Association (CAPCOA) released a draft update to its Hot Spots Public Notification Guidelines document for public review and comment.  Comments will be accepted by CAPCOA through October 31, 2016 and may be submitted by email, or by mail to:  Alan Abbs, Executive Director, CAPCOA, 1107 Ninth Street, Suite 1005, Sacramento, CA 95814.  CAPCOA may also schedule workshops for further input and comment.

The Hot Spots Public Notification Guidelines document will provide guidance to air districts for revising and implementing their own air toxic notification programs.  District programs must meet the requirements for public notification found in Health & Safety Code 44362(b).

If your facility now requires a preliminary risk evaluation, health risk assessment, public notification support, or other expanded AB 2588, air permit or CEQA compliance as a result of your air toxic emission risk levels, please contact us at (949) 567-9880.  For additional assistance, please contact:
