Subject: biogas -- Status on Activities to Support the Development of Biomethane Standards
From: lgonzale@arb.ca.gov

The purpose of this list serve notice is to provide interested
parties with an update on the status of efforts to develop
biomethane standards pursuant to AB 1900, and to invite
stakeholders to provide input to the process. 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.

ARB website at:  http://www.arb.ca.gov/energy/biogas/biogas.htm
