Oklahoma Administrative Code › Title 252 - Department of Environmental Quality › Chapter 100 - Water Quality Standards Implementation › Subchapter 8 - Permits for Part 70 Sources and Major New Source Review (NSR) Sources › Part 11 - VISIBILITY PROTECTION STANDARDS › Section 252:100-8-71 - Definitions

Current through Vol. 41, No. 20, July 1, 2024
The following words and terms when used in this Part shall
					 have the following meaning, unless the context clearly indicates otherwise. All
					 terms used in this Part that are not defined in this Subsection shall have the
					 meaning given to them in OAC
					 252:100-1-3,
					 252:100-8-1.1,
					 252:100-8-31, or in
					 the Oklahoma Clean Air Act.
"BART-eligible source"
means an existing
					 stationary facility as defined in this Section.
"Best Available Retrofit Technology"
or
"BART"
means an emission limitation based on the degree of
					 reduction achievable through the application of the best system of continuous
					 emission reduction for each pollutant which is emitted by a BART-eligible
					 source. The emission limitation must be established on a case-by-case basis,
					 taking into consideration the technology available, the costs of compliance,
					 the energy and non-air quality environmental impacts of compliance, any
					 pollution control equipment in use or in existence at the source, the remaining
					 useful life of the source, and the degree of improvement in visibility which
					 may reasonably be anticipated to result from the use of such technology.
"Deciview"
means a measurement of visibility
					 impairment. A deciview is a haze index derived from calculated light
					 extinction, such that uniform changes in haziness correspond to uniform
					 incremental changes in perception across the entire range of conditions, from
					 pristine to highly impaired. The deciview haze index is calculated based on the
					 following equation (for the purposes of calculating deciview, the atmospheric
					 light extinction coefficient must be calculated from aerosol measurements):
					 Deciview haze index=10 lne (bext/10 Mm*1); where
					 bext=the atmospheric light extinction coefficient, expressed in inverse
					 megameters (Mm*1).
"Existing stationary facility"
means any of
					 the following stationary sources of air pollutants, including any reconstructed
					 source, which was not in operation prior to August 7, 1962, and was in
					 existence on August 7, 1977, and has the potential to emit 250 TPY or more of
					 any air pollutant. In determining potential to emit, fugitive emissions, to the
					 extent quantifiable, must be counted.
(A) Fossil-fuel fired steam electric plants of more than
					 250 million Btu/hr input,
(B) Coal cleaning plants (thermal dryers),
(C) Kraft pulp mills,
(D) Portland cement plants,
(E) Primary zinc smelters,
(F) Iron and steel mill plants,
(G) Primary aluminum ore reduction plants,
(H) Primary copper smelters,
(I) Municipal incinerators capable of charging more than
					 250 tons of refuse per day,
(J) Hydrofluoric, sulfuric, and nitric acid plants,
(K) Petroleum refineries,
(L) Lime plants,
(M) Phosphate rock processing plants,
(N) Coke oven batteries,
(O) Sulfur recovery plants,
(P) Carbon black plants (furnace process),
(Q) Primary lead smelters,
(R) Fuel conversion plants,
(S) Sintering plants,
(T) Secondary metal production facilities,
(U) Chemical process plants,
(V) Fossil-fuel boilers of more than 250 million Btu per
					 hour heat input,
(W) Petroleum storage and transfer facilities with a
					 capacity exceeding 300,000 barrels,
(X) Taconite ore processing facilities,
(Y) Glass fiber processing plants, and
(Z) Charcoal production facilities
"In existence"
means that the owner or
					 operator has obtained all necessary preconstruction approvals or permits
					 required by the Department and EPA and either has:
(A) begun, or caused to begin, a continuous program of
					 physical on-site construction of the facility; or
(B) entered into binding agreements or contractual
					 obligations which cannot be cancelled or modified without substantial loss to
					 the owner or operator to undertake a program of construction of the facility to
					 be completed in a reasonable time.
"In operation"
means engaged in activity
					 related to the primary design function of the source.
"Integral vista"
means a view perceived from
					 within the mandatory Class I Federal area of a specific landmark or panorama
					 located outside the boundary of the mandatory Class I Federal area.
"Mandatory Class I Federal area"
means any
					 area identified in 40 CFR part 81, subpart D.
"Potential to emit"
means the maximum capacity
					 of a stationary source to emit a pollutant under its physical and operational
					 design. Any physical or operational limitation on the capacity of the source to
					 emit a pollutant including air pollution control equipment and restrictions on
					 hours of operation or on the type or amount of material combusted, stored, or
					 processed, shall be treated as part of its design if the limitation or the
					 effect it would have on emissions is federally enforceable. Secondary emissions
					 do not count in determining the potential to emit of a stationary
					 source.
"Reasonably attributable"
means attributable
					 by visual observation or any other technique the Department deems
					 appropriate.
"Secondary emissions"
means emissions which
					 occur as a result of the construction or operation of a BART-eligible source
					 but do not come from the BART-eligible source. Secondary emissions may include,
					 but are not limited to, emissions from ships or trains coming to or from the
					 BART-eligible source.
"Visibility in any mandatory Class I Federal
					 area"
includes any integral vista associated with that area.
