U.S. EPA's Proposed Rules to Regulate Power Plants

Under the federal Clean Air Act the U.S. EPA has proposed a rule to limit carbon emissions from future (Section 111(b)) and existing (Section 111(d)) fossil-fueled power plants. ARB is collaborating with the California Energy Commission (CEC) and the California Public Utilities Commission (CPUC) to develop a response to U.S. EPA on its proposed Clean Power Plan.  The public is invited to participate in workshops and provide comments. 

AB 1900 - Biomethane Renewable Resources:

AB 1900 (Chapter 602, 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, the Office of Environmental Health Hazard Assessment (OEHHA) and ARB, in consultation with other State agencies, are to undertake certain actions including determining health protective measures for constituents of concern and identifying monitoring, testing, reporting, and recordkeeping requirements necessary to ensure that health protective levels are maintained.

Renewable Electricity Standard (RES):

AB 32 creates a comprehensive, multi-year program to reduce GHG emissions to 1990 levels by the year 2020. Established in Executive Order S-21-09, ARB, under its AB 32 authority, was directed adopt a regulation requiring a 33 percent renewable energy target by 2020.  While ARB developed the RES, it was superseded by SB X1-2 in 2011.  More information about the RES and the State's renewables portfolio standard (RPS) is found in the links below. 

Combined Heat and Power (CHP) Systems:

AB 32 also directs ARB to prepare a Scoping Plan detailing methods to meet its GHG emission reduction goal. One of the possible emission reductions measures contained within ARB's Scoping Plan would increase the use of combined heat and power (CHP) systems. CHP refers to any system that generates electricity and useful thermal energy.

Sulfur Hexafluoride (SF6) for Gas Insulated Switchgear:

Sulfur hexafluoride (SF6) is one of the most very potent greenhouse gases, with a global warming potential approximately 23,000 times more powerful than carbon dioxide (CO2). ARB staff developed a regulation to reduce of SF6 emissions from gas insulated switchgears.

Distributed Generation:

SB 1298 (statutes of 2000) required ARB to adopt a certification program for Distributed Generation (DG) units that are exempt from local air district permits and to issue guidance for DG units that are subject to district permit. Currently, the CPUC and CEC are working to streamline state interconnection processes for DG.
