| (C) for opacity from boilers and combustion turbines
as defined in this section fueled by natural gas, coal, lignite, wood,
fuel oil containing hazardous air pollutants at a concentration of
less than 0.02% by weight, opacity that is equal to or exceeds 15
additional percentage points above the applicable limit, averaged
over a six-minute period. Opacity is the only RQ applicable to boilers
and combustion turbines described in this paragraph; or
(D) for facilities where air contaminant compounds
are measured directly by a continuous emission monitoring system providing
updated readings at a minimum 15-minute interval an amount, approved
by the executive director based on any relevant conditions and a screening
model, that would be reported prior to ground level concentrations
reaching at any distance beyond the closest regulated entity property
line:
(i) less than one-half of any applicable ambient air
standards; and
(ii) less than two times the concentration of applicable
air emission limitations.
(90) Rubbish--Nonputrescible solid waste, consisting
of both combustible and noncombustible waste materials. Combustible
rubbish includes paper, rags, cartons, wood, excelsior, furniture,
rubber, plastics, yard trimmings, leaves, and similar materials. Noncombustible
rubbish includes glass, crockery, tin cans, aluminum cans, metal furniture,
and like materials that will not burn at ordinary incinerator temperatures
(1,600 degrees Fahrenheit to 1,800 degrees Fahrenheit).
(91) Scheduled maintenance, startup, or shutdown activity--For
activities with unauthorized emissions that are expected to exceed
a reportable quantity (RQ), a scheduled maintenance, startup, or shutdown
activity is an activity that the owner or operator of the regulated
entity whether performing or otherwise affected by the activity, provides
prior notice and a final report as required by §101.211 of this
title (relating to Scheduled Maintenance, Startup, and Shutdown Reporting
and Recordkeeping Requirements); the notice or final report includes
the information required in §101.211 of this title; and the actual
unauthorized emissions from the activity do not exceed the emissions
estimates submitted in the initial notification by more than an RQ.
For activities with unauthorized emissions that are not expected to,
and do not, exceed an RQ, a scheduled maintenance, startup, or shutdown
activity is one that is recorded as required by §101.211 of this
title. Expected excess opacity events as described in §101.201(e)
of this title (relating to Emissions Event Reporting and Recordkeeping
Requirements) resulting from scheduled maintenance, startup, or shutdown
activities are those that provide prior notice (if required), and
are recorded and reported as required by §101.211 of this title.
(92) Sludge--Any solid or semi-solid, or liquid waste
generated from a municipal, commercial, or industrial wastewater treatment
plant; water supply treatment plant, exclusive of the treated effluent
from a wastewater treatment plant; or air pollution control equipment.
(93) Smoke--Small gas-born particles resulting from
incomplete combustion consisting predominately of carbon and other
combustible material and present in sufficient quantity to be visible.
(94) Solid waste--Garbage, rubbish, refuse, sludge
from a waste water treatment plant, water supply treatment plant,
or air pollution control equipment, and other discarded material,
including solid, liquid, semisolid, or containerized gaseous material
resulting from industrial, municipal, commercial, mining, and agricultural
operations and from community and institutional activities. The term
does not include:
(A) solid or dissolved material in domestic sewage,
or solid or dissolved material in irrigation return flows, or industrial
discharges subject to regulation by permit issued under the Texas
Water Code, Chapter 26;
(B) soil, dirt, rock, sand, and other natural or man-made
inert solid materials used to fill land, if the object of the fill
is to make the land suitable for the construction of surface improvements;
or
(C) waste materials that result from activities associated
with the exploration, development, or production of oil or gas, or
geothermal resources, and other substance or material regulated by
the Railroad Commission of Texas under Texas Natural Resources Code, §91.101,
unless the waste, substance, or material results from activities associated
with gasoline plants, natural gas liquids processing plants, pressure
maintenance plants, or repressurizing plants and is hazardous waste
as defined by the administrator of the United States Environmental
Protection Agency under the federal Solid Waste Disposal Act, as amended
by Resource Conservation and Recovery Act, as amended (42 United States
Code, §§6901 et seq.).
(95) Sour crude--A crude oil that will emit a sour
gas when in equilibrium at atmospheric pressure.
(96) Sour gas--Any natural gas containing more than
1.5 grains of hydrogen sulfide per 100 cubic feet, or more than 30
grains of total sulfur per 100 cubic feet.
(97) Source--A point of origin of air contaminants,
whether privately or publicly owned or operated. Upon request of a
source owner, the executive director shall determine whether multiple
processes emitting air contaminants from a single point of emission
will be treated as a single source or as multiple sources.
(98) Special waste from health care-related facilities--A
solid waste that if improperly treated or handled, may serve to transmit
infectious disease(s) and that is comprised of the following: animal
waste, bulk blood and blood products, microbiological waste, pathological
waste, and sharps.
(99) Standard conditions--A condition at a temperature
of 68 degrees Fahrenheit (20 degrees Centigrade) and a pressure of
14.7 pounds per square inch absolute (101.3 kiloPascals).
(100) Standard metropolitan statistical area--An area
consisting of a county or one or more contiguous counties that is
officially so designated by the United States Bureau of the Budget.
(101) Submerged fill pipe--A fill pipe that extends
from the top of a tank to have a maximum clearance of six inches (15.2
centimeters) from the bottom or, when applied to a tank that is loaded
from the side, that has a discharge opening entirely submerged when
the pipe used to withdraw liquid from the tank can no longer withdraw
liquid in normal operation.
(102) Sulfur compounds--All inorganic or organic chemicals
having an atom or atoms of sulfur in their chemical structure.
(103) Sulfuric acid mist/sulfuric acid--Emissions of
sulfuric acid mist and sulfuric acid are considered to be the same
air contaminant calculated as H2SO4 and must include sulfuric acid liquid mist,
sulfur trioxide, and sulfuric acid vapor as measured by Test Method
8 in 40 Code of Federal Regulations Part 60, Appendix A.
(104) Sweet crude oil and gas--Those crude petroleum

(107) True vapor pressure--The absolute aggregate partial
vapor pressure, measured in pounds per square inch absolute, of all
volatile organic compounds at the temperature of storage, handling,
or processing.
(108) Unauthorized emissions--Emissions of any air
contaminant except water, nitrogen, ethane, noble gases, hydrogen,
and oxygen that exceed any air emission limitation in a permit, rule,
or order of the commission or as authorized by Texas Health and Safety
Code, §382.0518(g).
(109) Unplanned maintenance, startup, or shutdown activity--For
activities with unauthorized emissions that are expected to exceed
a reportable quantity or with excess opacity, an unplanned maintenance,
startup, or shutdown activity is:
(A) a startup or shutdown that was not part of normal
or routine facility operations, is unpredictable as to timing, and
is not the type of event normally authorized by permit; or
(B) a maintenance activity that arises from sudden
and unforeseeable events beyond the control of the operator that requires
the immediate corrective action to minimize or avoid an upset or malfunction.
(110) Upset event--An unplanned and unavoidable breakdown
or excursion of a process or operation that results in unauthorized
emissions. A maintenance, startup, or shutdown activity that was reported
under §101.211 of this title (relating to Scheduled Maintenance,
Startup, and Shutdown Reporting and Recordkeeping Requirements), but
had emissions that exceeded the reported amount by more than a reportable
quantity due to an unplanned and unavoidable breakdown or excursion
of a process or operation is an upset event.
