|SF6 Reductions from Non-Electric and Non-Semiconductor Applications|
hexafluoride is a potent greenhouse gas, with a global warming
potential (GWP) of 23,900, the highest identified by
the Intergovernmental Panel on Climate Change. On
October 25, 2007, the California Air Resources Board (ARB)
approved sulfur hexafluoride reductions from non-electric and
non-semiconductor applications as
action measure. Accordingly, ARB staff developed a
measure to reduce sulfur hexafluoride emissions from other
uses including magnesium die-casting, fume vent
hood testing, tracer gas use, and other niche uses. Sulfur hexafluoride
emissions from semiconductor manufacture and electric utilities are
being examined separately. ARB approved the Regulation for
Reducing Sulfur Hexafluoride Emissions in February
On January 1, 2010, the regulation became effective. Restrictions on use and sale began January 1, 2011. Registration, reporting, and recordkeeping requirements became effective March 30, 2010. The reporting deadline is March 30 of each year, beginning in 2011.
Restrictions as of January 1, 2013 - In addition to the restrictions that had previously gone into effect, use of SF6 for Tracer Gas Testing, Magnesium Sand Casting, Magnesium Investment Casting, and Military Applications (other than Military Tracer Gas Array use) is no longer allowed in California, beginning January 1, 2013, without a valid exemption from ARB. Please review the regulation here.
The next sales reporting deadline is March 30, 2014 - Please fill in the reporting form and return via email attachment to firstname.lastname@example.org and email@example.com prior to the end of the day on March 30, 2014.
