biogas -- Upcoming CPUC Workshop on Biogas Standards

Posted: 19 Mar 2013 13:14:47
This is to inform you that on March 27, 2013, the California
Public Utilities Commission will be conducting a prehearing
conference and workshop regarding the development of biogas
standards per Assembly Bill 1900 (Statutes of 2012, Chapter 602).
During the workshop, staff from the California Air Resources
Board and the Office of Environmental Health Hazard Assessment
will provide a status report on efforts to develop health-based
standards for constituents of concern that may be found in
biogas.  For more information on the workshop, please see the

AB 1900, authored by Assemblyman Mike Gatto, requires the
California Public Utilities Commission (CPUC) to develop
standards for constituents in biogas to protect human health and
pipeline integrity and safety.  In support of the CPUC standards
development efforts, the Office of Environmental Health Hazard
Assessment (OEHHA) and the Air Resources Board (ARB), in
consultation with other State agencies, are to undertake certain
actions.  Specifically, OEHHA is tasked with compiling a list of
constituents of concern (constituents) found in biogas that could
pose a health risk and that are at levels that significantly
exceed the concentrations of those constituents in natural gas. 
OEHHA is also to determine health protective levels for these
constituents.  ARB is tasked with developing realistic exposure
scenarios and identifying the associated health risk to utility
workers and gas end users; determining the concentrations of
these constituents in biogas necessary to protect public health;
and identifying monitoring, testing, reporting, and recordkeeping
requirements necessary to ensure that health protective levels
are maintained.
