biogas -- 2nd Follow-up Discussion to March 27 California Public Utilities Commission Workshop on Biomethane Standards per Assembly Bill 1900

Posted: 17 Apr 2013 15:53:54
On April 25, 2013, the staff of the Air Resources Board (ARB) and
the Office of Environmental Health Hazard Assessment (OEHHA) will
meet with interested parties for further discussion of comments
and questions raised on March 27 at the California Public
Utilities Commission (CPUC) workshop on Assembly Bill (AB) 1900. 

AB 1900 (Gatto, Statutes of 2012) requires the 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, OEHHA and ARB, in consultation with other
State agencies, are to undertake certain actions.  Specifically,
OEHHA is tasked with compiling a list of constituents of concern
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, after considering
potential health impacts and risks.  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. 
This will be the second follow-up meeting on the March 27 CPUC
workshop.  During the first meeting, on April 10, staff presented
preliminary ideas on the format of the health based standards,
analytical test methods, and monitoring frequency.  For the April
25 meeting, staff will present revised ideas on the same topics
based on the comments received by interested parties.  More
information will be provided prior to the meeting at ARBs
website here: http://www.arb.ca.gov/energy/biogas/biogas.htm.

The meeting will be held at the time and location listed below:
Date: 		April 25, 2013
Time: 		9:30 a.m.  12:30 p.m.
