241.3, as amended.
(b) This definition of biomass is not
intended to suggest that these materials are or are not solid waste.
(1-2) "Capacity factor" means:

gas supply after notification; or
(b) To limit the gas supply by automatic
interruption.
(8)
"Operating time" means, for the purpose of determining compliance or
non-compliance with this chapter, the actual time in hours that an affected
unit operates, beginning when operation of the draft fans is established and
ending when feed of the primary fuel to the combustion chamber is
discontinued.
(9) "Manufacturer"
means a person who imports, manufactures, assembles, or produces a small wood

outdoor installation or indoor installation; and
(d) That distributes heated fluid through
pipes for the purpose of supplying heat and/or hot water to building
spaces.
(15) "Space
heater" means fuel-burning equipment that consumes more than 60 percent of its
annual fuel during the period from October 31 of one year through March 31 of
the following year. For the purpose of this regulation, annual fuel use is the
total fuel consumed during the period October 1 of one year to September 30 of
the following year, beginning October 1, 1989.
(16) "System" means all combustion equipment
owned or operated by a single business entity.
