The Environmental Improvement Board amended N.M. Code §20.2.73 to require that sources using a different emission monitoring or calculation method than was used to report sulfur dioxide emissions in 2006 adjust their reported emissions to be comparable to the emission monitoring or calculation method that was used in 2006. Changes took effect July 6, 2011. http://www.nmcpr.state.nm.us/nmregister/xxii/xxii12/20.2.73amend.htm.
