For the purpose of these rules and the rules in 567-Chapters
20 through 35, the following terms shall, unless otherwise noted, have the
meaning indicated in this chapter. Additional definitions potentially
applicable to this chapter are set forth in 567-Chapters 22 and 23. The
definitions set out in Iowa Code sections
455B.101,
455B.131, and
455B.411 are incorporated
verbatim into these rules.
"Air pollution alert" means the action
condition declared when the concentrations of air contaminants reach the level
at which the first-stage control actions are to begin.
"Air pollution emergency" means the action
condition declared when the air quality is continuing to degrade to a level
that should never be reached, and that the most stringent control actions are
necessary.
"Air pollution episode" means a combination
of forecast or actual meteorological conditions and emissions of air
contaminants that may or do present an imminent and substantial endangerment to
the health of persons, during which the chief meteorological factors are the
absence of winds that disperse air contaminants horizontally and a stable
atmospheric layer that tends to inhibit vertical mixing through relatively deep
layers.
"Air pollution forecast" means an air
stagnation advisory issued to the department, the commission, and appropriate
air pollution control agencies by an authorized Air Stagnation Advisory Office
of the National Weather Service predicting that meteorological conditions
conducive to an air pollution episode may be imminent. This advisory may be
followed by a prediction of the duration and termination of such meteorological
conditions.
"Air pollution warning" means the action
condition declared when the air quality is continuing to degrade from the
levels classified as an air pollution alert, and where control actions in
addition to those conducted under an air pollution alert are necessary.
"Equipment" means equipment capable of
emitting air contaminants to produce air pollution.
"Excess emission" means any emission that
exceeds any applicable emission standard prescribed in 567-Chapter 23 or
567-22.4 (455B),
567-22.5 (455B),
567-31.3 (455B), or
567-33.3 (455B) or any emission
limit specified in a permit or order.
"Existing equipment" means equipment,
machines, devices, or installations that were in operation prior to September
23, 1970.
"Malfunction" means any sudden and
unavoidable failure of control equipment or of a process to operate in a normal
manner. Any failure that is caused entirely or in part by poor maintenance,
careless operation, lack of an adequate maintenance program, or any other
preventable upset condition or preventable equipment breakdown shall not be
considered a malfunction.
"New equipment" means, except for any
equipment or modified equipment to which 567-subrule 23.1(2) applies, any
equipment or control equipment not under construction or for which components
have not been purchased on or before September 23, 1970, and any equipment that
is altered or modified after such date, which may cause, eliminate, reduce, or
control the emission of air contaminants.
"Opacity" means the degree to which
emissions reduce the transmission of light and obscure the view of an object in
the background.
"Shutdown" means the cessation of operation
of any control equipment or process equipment or process for any
purpose.
"Startup" means the setting into operation
of any control equipment or process equipment or process for any
purpose.
(1)
New
equipment. All new equipment and all new control equipment, as defined
herein, installed in this state shall perform in conformance with applicable
emission standards specified in 567-Chapter 23.
(2)
Existing equipment. All
existing equipment, as defined herein, shall be operated in conformance with
applicable emission standards specified in 567-Chapter 23 or as otherwise
specified herein, except that the performance standards specified in
567-subrule 23.1(2) shall not apply to existing equipment.
(3)
Emissions inventory. The
person responsible for
equipment as defined herein shall provide information on
fuel use, materials processed, air contaminants emitted (including greenhouse
gases as "
greenhouse gas" is defined in
567-22.1 (455B)), estimated rate
of emissions, periods of emissions, or other air pollution information to the
director upon the director's written request for use in compiling and
maintaining an
emissions inventory for evaluation of the air pollution
situation in the state and its various parts. The information requested shall
be submitted in the electronic format specified by the department, if
electronic submittal is provided. All information in regard to both actual and
allowable emissions shall be public records, and any publication of such data
shall be limited to actual and allowable air contaminant emissions.
(4) Reserved.
(5)
Public availability of
data. Emission data obtained from owners or operators of stationary
sources under the provisions of 21.1(3) and any correlations with applicable
emission limitations or other control measures will be made available to the
public on the department's website and upon request.
(6)
Maintenance of record.
Each owner or operator of any stationary source, as defined herein, shall, upon
notification from the director, maintain records of the nature and amounts of
air contaminant emissions from such source and any other information as may be
deemed necessary by the commission to determine whether such source is in
compliance with the applicable emission limitations or other control measures.
The information recorded shall be summarized and reported monthly to the
director on forms furnished by the department. The initial reporting period
shall commence 60 days from the date the director issues notification of the
recordkeeping requirements. Records shall be retained by the owner or operator
for two years after the date on which the pertinent report is
submitted.
