used. (3-28-23)
e. A pilot plant is
defined as a stationary source located at least one quarter (%) mile from any
sensitive receptor; functions to test processing, mechanical, or pollution
control equipment's full-scale feasibility; and does not produce products for
sale except in developmental quantities. It uses a slip stream of no more than
ten percent (10%) from an existing process stream and satisfies the following:
(3-28-23)
i. The source must comply with
Section 223. For
carcinogen emissions, the owner or operator may utilize a short-term adjustment
factor of ten (10) by multiplying either the acceptable ambient concentration
or the screening emissions level, but not both, by ten (10);
(3-28-23)
ii. The source is not
required to obtain approval to construct in accordance with the applicable
radionuclides standard in 40 CFR Part 61 , Subpart H; and (3-28-23)
iii. The exemption for a pilot plant
terminates one (1) year after the commencement of operations and may not be
renewed. (3-28-23)
02. Other Exempt Sources. A source that satisfies the criteria set forth in Section 220 and that is specified below: (3-28-23)
a. Air conditioning or ventilating
equipment not designed to remove air pollutants generated by or released from
equipment. (3-28-23)
b. Air
pollutant detectors or recorders, combustion controllers, or combustion
shutoffs. (3-28-23)
c. Fuel burning
equipment for indirect heating and for heating and reheating furnaces using
natural gas, propane gas, liquefied petroleum gas, or biogas (gas produced by
the anaerobic decomposition of organic material through a controlled process)
with hydrogen sulfide concentrations less than two hundred (200) ppmv
exclusively with a capacity of less than fifty (50) million btu's per hour
input. (3-28-23)
d. Other fuel
burning equipment for indirect heating with a capacity of less than one million
(1,000,000) btu's per hour input. (3-28-23)
e. Mobile internal combustion engines, marine
installations and locomotives. (3-28-23)
f. Agricultural activities and services.
(3-28-23)
g. Retail gasoline,
natural gas, propane gas, liquefied petroleum gas, distillate fuel oils and
diesel fuel sales. (3-28-23)
h.
Used Oil Fired Space Heaters which comply with all the following criteria:
(3-28-23)
i. The used oil-fired space heater
burns only used oil that the owner or operator generates on site, that is
derived from households, such as used oil generated by individuals maintaining
their personal vehicles, or on-specification used oil that is derived from
commercial generators provided that the generator, transporter and owner or
operator burning the oil for energy recovery comply fully with IDAPA
58.01.05.015, "Rules and Standards for Hazardous Waste"; (3-28-23)
(1) For the purposes of Subsection
222.02.h., "used oil" refers
to any oil that has been refined from crude oil or any synthetic oil that has
been used and, as a result of such use, is contaminated by physical or chemical
impurities. (3-28-23)
(2) For the
purposes of Subsection
222.02.h., "used oil fired
space heater" refers to any furnace or apparatus and all appurtenances thereto,
designed, constructed and used for combusting used oil for energy recovery to
directly heat an enclosed space. (3-28-23)
ii. Any used oil burned is not contaminated
by added toxic substances such as solvents, antifreeze or other household and
industrial chemicals; (3-28-23)
iii. The used oil-fired space heater is
designed to have a maximum capacity of not more than one half (0.5) million BTU
per hour; (3-28-23)
iv. The
combustion gases from the used oil-fired space heater are vented to the ambient
air through a stack equivalent to the type and design specified by the
manufacturer of the heater and installed to minimize down wash and maximize
dispersion; and (3-28-23)
v. The
used oil-fired space heater is of modern commercial design and manufacture,
except that a homemade used oil-fired space heater may be used if, prior to the
operation of the homemade unit, the owner or operator submits documentation to
the Department demonstrating, to the satisfaction of the Department, that
emissions from the homemade unit are no greater than those from modern
commercially available units. (3-28-23)
i. Multiple chamber crematory retorts used to
cremate human or animal remains using natural gas exclusively with a maximum

(1500) degrees Fahrenheit while operating. (3-28-23)
j. Petroleum environmental remediation source

are available at the DEQ website at http://www.deq.idaho.gov, to help assist
sources in this exemption determination. (3-28-23)
