harp -- CAPCOA releases draft update of the Facility Prioritization Guidance document for public comment

Posted: 22 Apr 2016 07:18:05
The California Air Pollution Control Officers Association
(CAPCOA) has released a Draft update to their Facility
Prioritization Guidance document for public review and comment.
This document is available at the CAPCOA website www.capcoa.org. 
CAPCOA will be accepting comments through June 3, 2016. Based on
comments submitted, CAPCOA may schedule workshops for further
opportunities to comment.

The Facility Prioritization Guidelines were developed by the
Toxics and Risk Managers Committee (TARMAC) of CAPCOA in response
to revisions to the State Office of Health Hazard Assessment’s
(OEHHA) health risk assessment methodologies contained in the Air
Toxics Hot Spots Program Risk Assessment Guidelines: Guidance
Manual for the Preparation of Health Risk Assessments (February
2015). The purpose of the Risk Prioritization Guidelines document
is to provide California air pollution control and air quality
management districts with suggested procedures for use in
prioritizing facilities into high, intermediate, and low priority
categories as required by the Air Toxics "Hot Spots" Information
and Assessment Act of 1987 (Air Toxics "Hot Spots" Act) in
accordance with Health and Safety Code §44344.4(c). This law
established a statewide program for inventory of air toxics
emissions from individual facilities as well as requirements for
risk assessment and public notification. Appendix A contains a
copy of the Air Toxics "Hot Spots" Act.

These guidelines were originally developed in 1990 and are being
revised to incorporate the new health risk assessment
methodologies determined by OEHHA in February 2015
http://oehha.ca.gov/air/hot_spots/2015/2015GuidanceManual.pdf. 
To allow districts to continue to use existing risk
prioritization programs and related software, the 2015 updated
prioritization guidelines were revised to incorporate revised
carcinogenic normalization factors to account for the new
methodologies. CAPCOA understands the existing approach has
limitations and will evaluate the need to expand the
prioritization guidelines to better address variations due to
source types and changes in air dispersion modeling programs.

The guidelines are available to those districts that choose to
use them. However, there is no requirement that the districts use
these specific guidelines. Furthermore, it should be recognized
that any district may develop prioritization procedures other
than those presented in these guidelines. 

It should be noted that any District that develops and utilizes
its own prioritization guidelines must still provide public
notification for any facility with a risk above the District’s
notification threshold level that is at least as stringent as
those required under the AB2588 (i.e. Health and Safety Code
Sections 44300-44394).
