Current through Register Vol. 48, No. 6, June 28, 2024
(a)
				  A solid waste exhibits the characteristic of ignitability if a representative
				  sample of the waste has any of the following properties:
(1) It is a liquid, other than a solution
				  containing less than twenty-four percent (24%) alcohol by volume and at least
				  fifty percent (50%) water by weight, that has flash point less than 60 °C (140
				  °F), as determined by using one of the following ASTM standards: ASTM D93-79,
				  D93-80, D3278-78, D8174-18, or D8175-18 as specified in SW-846 Test Methods
				  1010B or 1020C (all incorporated by reference, see section 260.11).
(2) It is not a liquid and is capable under
				  standard temperature and pressure, of causing fire through friction, absorption
				  of moisture or spontaneous chemical changes, and when ignited, burns so
				  vigorously and persistently that it creates a hazard.
(3) It is an ignitable compressed gas.
(i) The term "compressed gas" shall designate
				  any material or mixture having in the container an absolute pressure exceeding
				  40 p.s.i. at 70 degrees F or, regardless of the pressure at 70 degrees F,
				  having an absolute pressure exceeding 104 p.s.i. at 130 degrees F; or any
				  liquid flammable material having a vapor pressure exceeding 40 p.s.i. absolute
				  at 100 degrees F as determined by ASTM Test D-323.
(ii) A compressed gas shall be characterized
				  as ignitable if any one of the following occurs:
(A) Either a mixture of thirteen percent
				  (13%) or less (by volume) with air forms a flammable mixture or the flammable
				  range with air is wider than twelve percent (12%) regardless of the lower
				  limit. These limits shall be determined at atmospheric temperature and
				  pressure. The method of sampling and test procedure shall be the ASTM E681-85
				  (incorporated by reference, see section 260.11), or other equivalent methods
				  approved by the Associate Administrator, Pipeline and Hazardous Materials
				  Safety Administration, U.S. Department of Transportation.
(B) It is determined to be flammable or
				  extremely flammable using
				  49 CFR
				  173.115(l).
(C) Using the Bureau of Explosives' Open Drum
				  Apparatus (see Note 1), there is any significant propagation of flame away from
				  the ignition source.
(D) Using the
				  Bureau of Explosives' Closed Drum Apparatus (see Note 1), there is any
				  explosion of the vapor-air mixture in the drum.
(4) It is an oxidizer. An oxidizer for the
				  purpose of this subchapter is a substance such as a chlorate, permanganate,
				  inorganic peroxide, or a nitrate, that yields oxygen readily to stimulate the
				  combustion of organic matter.
(i) An organic
				  compound containing the bivalent -O-O- structure and which may be considered a
				  derivative of hydrogen peroxide where one or more of the hydrogen atoms have
				  been replaced by organic radicals must be classed as an organic peroxide
				  unless:
(A) The material meets the definition
				  of a Division 1.1, 1.2, or 1.3 explosive, as defined in 261.23(a)(8), in which
				  case it must be classed as an explosive,
(B) The material is forbidden to be offered
				  for transportation according to
				  49 CFR
				  172.101 and
				  49 CFR
				  173.21,
(C) It is determined that the predominant
				  hazard of the material containing an organic peroxide is other than that of an
				  organic peroxide, or
(D) According
				  to data on file with the Pipeline and Hazardous Materials Safety Administration
				  in the U.S. Department of Transportation, it has been determined that the
				  material does not present a hazard in
				  transportation.
