Background

AB 1900, authored by Assemblyman Mike Gatto and chaptered into law on September 27, 2012 (Chapter 602, Statutes of 2012), 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
