(1) Terms used but not defined in this rule are defined in 40 CFR 60, Subparts A and B, and are incorporated by reference in ADEM Admin. Code chapter 335-3-10. For the purposes of this rule only, the following definitions apply:
(a)
"30-day rolling average" means the arithmetic mean of
the previous 720 hours of valid operating data. Valid data excludes periods
when this unit is not operating. The 720 hours should be consecutive, but not
necessarily continuous if operations are intermittent.
(b) "Administrator"
means the Administrator of the U.S. Environmental Protection Agency or his/her
authorized representative.
(c)
"Affirmative defense" means, in the context of an
enforcement proceeding, a response or defense put forward by a defendant
regarding which the defendant has the burden of proof, and the merits of which
are independently and objectively evaluated in a judicial or administrative
proceeding.
(d)
"Agricultural waste" means vegetative agricultural
materials such as nut and grain hulls and chaff (e.g., almond, walnut, peanut
rice, and wheat), bagasse, orchard prunings, corn stalks, coffee bean hulls and
grounds, and other vegetative waste materials generated as a result of
agricultural operations.
(e)
"Air curtain incinerator" means an incinerator that
operates by forcefully projecting a curtain of air across an open chamber or
pit in which combustion occurs. Incinerators of this type can be constructed
above or below ground and with or without refractory walls and floor. Air
curtain incinerators are not to be confused with conventional combustion
devices with enclosed fireboxes and controlled air technology such as mass
burn, modular, and fluidized bed combustors.
(f) "Annual heat
input" means the heat input for the 12 months preceding the
compliance demonstration.
(g)
"Auxiliary fuel" means natural gas, liquified
petroleum gas, fuel oil, or diesel fuel.
(h) "Average annual heat input
rate" means annual heat input divided by the hours of operation
for the 12 months preceding the compliance demonstration.
(i) "Bag leak detection
system" means an instrument that is capable of monitoring
particulate matter loadings in the exhaust of a fabric filter (i.e., baghouse)
in order to detect bag failures. A bag leak detection system includes, but is
not limited to, an instrument that operates on triboelectric, light scattering
light transmittance, or other principle to monitor relative particulate matter
loadings.
(j) "Burn-off
oven" means any rack reclamation unit, part reclamation unit, or
drum reclamation unit. A burn-off oven is not an incinerator, waste-burning
kiln, an energy recover unit or a small, remote incinerator under this
rule.
(k) "Bypass
stack" means a device used for discharging combustion gases to
avoid severe damage to the air pollution control device or other
equipment.
(l)
"Calendar quarter" means three consecutive months
(nonoverlapping) beginning on: January 1, April 1, July 1, or October
1.
(m) "Calendar
year" means 365 consecutive days starting on January 1 and ending
on December 31.
(n)
"CEMS data during startup and shutdown" means the
following: 1. For incinerators, small remote
incinerators: CEMS data collected during the first hours of a CISWI unit
startup from a cold start until waste is fed into the unit and the hours of
operation following the cessation of waste material being fed to the CISWI
during a unit shutdown. For each startup event, the length of time that CEMS
data may be claimed as being CEMS data during startup must be 48 operating
hours or less. For each shutdown event, the length of time that CEMS data may
be claimed as being CEMS data during shutdown must be 24 operating hours or
less.
2. For energy recovery units
CEMS data collected during the startup or shutdown periods of operation
Startup begins with either the first-ever firing of fuel in a boiler or process
heater for the purpose of supplying useful thermal energy (such as steam or
heat) for heating, cooling or process purposes, or producing electricity, or
the firing of fuel in a boiler or process heater for any purpose after a
shutdown event. Startup ends four hours after when the boiler or process heater
makes useful thermal energy (such as heat or steam) for heating, cooling, or
process purposes, or generates electricity or when no fuel is being fed to the
boiler or process heater, whichever is earlier. Shutdown begins when the boiler
or process heater no longer makes useful thermal energy (such as heat or steam)
for heating, cooling, or process purposes and/or generates electricity or when
no fuel is being fed to the boiler or process heater, whichever is earlier.
Shutdown ends when the boiler or process heater no longer makes useful thermal
energy (such as steam or heat) for heating, cooling, or process purposes and/or
generates electricity, and no fuel is being combusted in less;
3. For waste-burning kilns: CEMS data
collected during the periods of kiln operation that do not include normal
operations. Startup means the time from when a shutdown kiln first begins
firing fuel until it begins producing clinker. Startup begins when a shutdown
kiln turns on the induced draft fan and begins firing fuel in the main burner.
Startup ends when feed is being continuously introduced into the kiln for a
least 120 minutes or when the feed rate exceeds 60 percent of the kiln design
limitation rate, whichever occurs first. Shutdown means the cessation of kiln
operation. Shutdown begins when feed to the kiln is halted and ends when
continuous kiln rotation ceases.
(o) "Chemical recovery
unit" means combustion units burning materials to recover chemical
constituents or to produce chemical compounds where there is an existing
commercial market for such recovered chemical constituents or compounds. A
chemical recovery unit is not an incinerator, a waste-burning kiln, an energy
recovery unit or a small, remote incinerator under this rule. The following
seven types of units are considered chemical recovery units:
1. Units burning only pulping liquors (i.e.,
black liquor) that are reclaimed in a pulping liquor recovery process and
reused in the pulping process.
2.
Units burning only spent sulfuric acid used to produce virgin sulfuric
acid.
3. Units burning only wood or
coal feedstock for the production of charcoal.
4. Units burning only manufacturing byproduct
streams/residue containing catalyst metals that are reclaimed and reused as
catalysts or used to produce commercial grade catalysts.
5. Units burning only coke to produce
purified carbon monoxide that is used as an intermediate in the production of
other chemical compounds.
6. Units
burning only hydrocarbon liquids or solids to produce hydrogen, carbon
monoxide, synthesis gas, or other gases for use in other manufacturing
processes.
7. Units burning only
photographic film to recover silver.
(p) "Chemotherapeutic
waste" means waste material resulting from the production or use
of antineoplastic agents used for the purpose of stopping or reversing the
growth of malignant cells.
(q)
"Clean lumber" means wood or wood products that have
been cut or shaped and include wet, air-dried, and kiln-dried wood products.
Clean lumber does not include wood products that have been painted,
pigment-stained, or pressure-treated by compounds such as chromate copper
arsenate, pentachlorophenol, and creosote.
(r) "Commercial and industrial
solid waste incineration (CISWI)" means any distinct operating
unit of any commercial or industrial facility that combusts, or has combusted
in the preceding 6 months, any solid waste as that term is defined in 40 CFR
part 241. If the operating unit burns material other than traditional fuels as
defined in §241.2 that have been discarded, and the owner or operator does not
keep and produce records as required by subparagraph (ll)(u) of this rule, the
operating unit is a CISWI. While not all CISWIs will include all of the
following components, a CISWI includes, but is not limited to, the solid waste
feed system, grate system, flue gas system, waste heat recovery equipment, if
any, and bottom ash system. The CISWI does not include air pollution control
equipment or the stack. The CISWI boundary starts at the solid waste hopper (if
applicable) and extends through two areas:1.
The combustion unit flue gas system, which ends immediately after the last
combustion chamber or after the waste heat recovery equipment, if any;
and
2. The combustion unit bottom
ash system, which ends at the truck loading station or similar equipment that
transfers the ash to final disposal. The CISWI unit includes all ash handling
systems connected to the bottom ash handling system.
3. A CISWI unit does not include any of the
types of units described in subparagraph (2)(d) of this rule, nor does it
include any combustion turbine or reciprocating internal combustion
engine.
(s)
"Contained gaseous material" means gases that are in a
container when that container is combusted.
(t) "Continuous emission
monitoring system (CEMS)" means the total equipment that may be
required to meet the data acquisition and availability requirements of this
rule, used to sample...
