The Department of Ecology amended Wash. Admin. Code §173.401.200 to mandate greenhouse gas reporting. Beginning January 1, 2011, sources with an air operating permit must report their greenhouse gas emissions when revising or renewing this permit. Beginning July 1, 2011, sources that have the potential to emit 100,000 tons per year or more of greenhouse gases become subject to the air operating permit program, regardless of their emissions of other pollutants. These newly subject sources must apply for an air operating permit on or before July 1, 2012. http://apps.leg.wa.gov/documents/laws/wsr/2010/24/10-24-114.htm.
