Purpose of the Workshop
CARB staff is proposing to amend the Regulation to further reduce greenhouse gas emissions from gas-insulated equipment in the electricity transmission and distribution sector. In response to comments received on materials presented in February, this workshop is intended to discuss stakeholder feedback on key topics, share CARB staff responses, and to solicit further feedback. Staff will provide updates on the potential regulatory changes, process, and tentative schedule.
Following the workshop, stakeholders will have an opportunity to provide written comments during an informal comment period, which will conclude at 5:00 p.m. Pacific time on Thursday, August 29, 2019.
All interested stakeholders are invited to attend. For those unable to attend in person, the workshop will be webcast.
Relevant materials will be available on CARB’s Electricity Transmission and Distribution Greenhouse Gas Emissions “Meetings and Workshops” webpage prior to the workshop.
Background
As part of compliance with the Global Warming Solutions Act of 2006 (Assembly Bill 32), the Board adopted the Regulation in 2010. The Regulation requires gas-insulated switchgear owners to lower their SF6 emission rate to one percent by 2020. SF6 is the most potent of the six main greenhouse gases with a global warming potential over 20,000 times that of CO2 over 100 years. It also has an extremely long atmospheric lifetime of about 3,200 years.
