Table Notes:
Note 1: For Two
				  Release Source Column: 1=RQ as listed in 40 C.F.R. Part 302; 2=RQ as listed in
				  40 C.F.R. Part 355; 3=Two Release Quantity as determined in "Technical Basis
				  Document for C.A.P.P. Two Release Quantities and Toxic Endpoints."
Note 2: The threshold quantity must be applied to the fraction of the
				  chemical in the actual mixture.
* These substances must be
				  involved in a fire or explosion to qualify as a release pursuant to
				  subparagraph (2) of paragraph (a) of subsection 1 of NAC 459.95323.
2. Except as otherwise provided in
				  subsection 3, a substance must be classified as an explosive if the substance
				  is classified as division 1.1, 1.2, 1.3, 1.4 or 1.5 in column 3 of the Table of
				  Hazardous Materials in
				  49 C.F.R. §
										172.101, which is adopted by reference
				  pursuant to NAC 459.95528.
3. The
				  list of explosives as classified pursuant to subsection 2 excludes those
				  substances described in
				  18 U.S.C. §
										845(a).
4. If a substance:
(a) Is listed as a highly hazardous substance
				  pursuant to subsection 1; and
(b)
				  Is also classified as an explosive pursuant to subsection 2 which is not
				  excluded pursuant to subsection 3, the substance must be treated as a highly
				  hazardous substance for the purposes of NAC 459.952 to 459.95528, inclusive, if
				  the substance is present in the process in excess of the threshold quantity set
				  forth for the substance pursuant to subsection 1.
