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 ARB’s 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. Location: California Environmental Protection Agency 1001 “I” Street Sacramento, CA 95814 Room 550 For those unable to participate in the discussion in person, a telephone conference line will be available. Callers in the United States can participate starting at 9:30 Pacific Daylight Time by dialing 800-369-2054, and using access code 5759675.
