(ii) if not listed in clause (i) of this subparagraph,
100 pounds;
(iii) for greenhouse gases, individually or collectively,
there is no reportable quantity, except for the specific individual
air contaminant compounds listed in this paragraph;
(B) for mixtures of air contaminant compounds:
(i) where the relative amount of individual air contaminant
compounds is known through common process knowledge or prior engineering
analysis or testing, any amount of an individual air contaminant compound
that equals or exceeds the amount specified in subparagraph (A) of
this paragraph;
(ii) where the relative amount of individual air contaminant
compounds in subparagraph (A)(i) of this paragraph is not known, any
amount of the mixture that equals or exceeds the amount for any single
air contaminant compound that is present in the mixture and listed
in subparagraph (A)(i) of this paragraph;

compounds listed in subparagraph (A)(i) of this paragraph are known
to be less than 0.02% by weight of the mixture, and each of the other
individual air contaminant compounds covered by subparagraph (A)(ii)
of this paragraph are known to be less than 2.0% by weight of the
mixture, any total amount of the mixture of air contaminant compounds
greater than or equal to 5,000 pounds; or
(iv) where natural gas excluding carbon dioxide, water,
nitrogen, methane, ethane, noble gases, hydrogen, and oxygen or air
emissions from crude oil are known to be in an amount greater than
or equal to 5,000 pounds or the associated hydrogen sulfide and mercaptans

(C) for opacity from boilers and combustion turbines

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

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.).
