visibility requirement under part C of title I of the Act, but only as 
it would apply to temporary sources permitted pursuant to section 504(e) 
of the Act.
    Designated representative shall have the meaning given to it in 
section 402(26) of the Act and the regulations promulgated thereunder.
    Draft permit means the version of a permit for which the permitting 
authority offers public participation under Sec. 70.7(h) or 
affected State review under Sec. 70.8 of this part.
    Emissions allowable under the permit means a federally enforceable 
permit term or condition determined at issuance to be required by an 
applicable requirement that establishes an emissions limit (including a 
work practice standard) or a federally enforceable emissions cap that 
the source has assumed to avoid an applicable requirement to which the 
source would otherwise be subject.
    Emissions unit means any part or activity of a stationary source 
that emits or has the potential to emit any regulated air pollutant or 
any pollutant listed under section 112(b) of the Act. This term is not 
meant to alter or affect the definition of the term 
``unit'' for purposes of title IV of the 
Act.
    The EPA or the Administrator means the Administrator of the EPA or 
his designee.
    Final permit means the version of a part 70 permit issued by the 
permitting authority that has completed all review procedures required 
by Sec.Sec. 70.7 and 70.8 of this part.
    Fugitive emissions are those emissions which could not reasonably 
pass through a stack, chimney, vent, or other functionally-equivalent 
opening.
    General permit means a part 70 permit that meets the requirements of 
Sec. 70.6(d).
    Major source means any stationary source (or any group of stationary 
sources that are located on one or more contiguous or adjacent 
properties, and are under common control of the same person (or persons 
under common control)) belonging to a single major industrial grouping 
and that are described in paragraph (1), (2), or (3) of this definition. 
For the purposes of defining ``major 
source,'' a stationary source or group of stationary 
sources shall be considered part of a single industrial grouping if all 
of the pollutant emitting activities at such source or group of sources 
on contiguous or adjacent properties belong to the same Major Group 
(i.e., all have the same two-digit code) as described in the Standard 
Industrial Classification Manual, 1987.
    (1) A major source under section 112 of the Act, which is defined 
as:
    (i) For pollutants other than radionuclides, any stationary source 
or group of stationary sources located within a contiguous area and 
under common control that emits or has the potential to emit, in the 
aggregate, 10 tons per year (tpy) or more of any hazardous air pollutant 
which has been listed pursuant to section 112(b) of the Act, 25 tpy or 
more of any combination of such hazardous air pollutants, or such lesser 
quantity as the Administrator may establish by rule. Notwithstanding the 
preceding sentence, emissions from any oil or gas exploration or 
production well (with its associated equipment) and emissions from any 
pipeline compressor or pump station shall not be aggregated with 
emissions from other similar units, whether or not such units are in a 
contiguous area or under common control, to determine whether such units 
or stations are major sources; or
    (ii) For radionuclides, ``major source'' 
shall have the meaning specified by the Administrator by rule.
    (2) A major stationary source of air pollutants, as defined in 
section 302 of

[[Page 209]]

the Act, that directly emits or has the potential to emit, 100 tpy or 
more of any air pollutant (including any major source of fugitive 
emissions of any such pollutant, as determined by rule by the 
Administrator). The fugitive emissions of a stationary source shall not 
be considered in determining whether it is a major stationary source for 
the purposes of section 302(j) of the Act, unless the source belongs to 
one of the following categories of stationary source:
    (i) Coal cleaning plants (with thermal dryers);
    (ii) Kraft pulp mills;
    (iii) Portland cement plants;
    (iv) Primary zinc smelters;
    (v) Iron and steel mills;

capacity exceeding 300,000 barrels;
    (xxiii) Taconite ore processing plants;
    (xxiv) Glass fiber processing plants;
    (xxv) Charcoal production plants;
    (xxvi) Fossil-fuel-fired steam electric plants of more than 250 
million British thermal units per hour heat input; or
    (xxvii) Any other stationary source category, which as of August 7, 
1980 is being regulated under section 111 or 112 of the Act.
    (3) A major stationary source as defined in part D of title I of the 
Act, including:
    (i) For ozone nonattainment areas, sources with the potential to 
emit 100 tpy or more of volatile organic compounds or oxides of nitrogen 
in areas classified as ``marginal'' or 
``moderate,'' 50 tpy or more in areas 
classified as ``serious,'' 25 tpy or more in 
areas classified as ``severe,'' and 10 tpy 
or more in areas classified as ``extreme''; 
except that the references in this paragraph to 100, 50, 25 and 10 tpy 
of nitrogen oxides shall not apply with respect to any source for which 
the Administrator has made a finding, under section 182(f) (1) or (2) of 
the Act, that requirements under section 182(f) of the Act do not apply;
    (ii) For ozone transport regions established pursuant to section 184 
of the Act, sources with the potential to emit 50 tpy or more of 
volatile organic compounds;
    (iii) For carbon monoxide nonattainment areas:
    (A) That are classified as ``serious,'' 
and
    (B) in which stationary sources contribute significantly to carbon 
monoxide levels as determined under rules issued by the Administrator, 
sources with the potential to emit 50 tpy or more of carbon monoxide; 
and
    (iv) For particulate matter (PM-10) nonattainment areas classified 
as ``serious,'' sources with the potential 
to emit 70 tpy or more of PM-10.
    Part 70 permit or permit (unless the context suggests otherwise) 
means any permit or group of permits covering a part 70 source that is 
issued, renewed, amended, or revised pursuant to this part.
    Part 70 program or State program means a program approved by the

the requirements of Sec. 70.7(e) of this part.
    Permit program costs means all reasonable (direct and indirect) 
costs required to develop and administer a permit program, as set forth 
in Sec. 70.9(b) of this

[[Page 210]]

part (whether such costs are incurred by the permitting authority or 
other State or local agencies that do not issue permits directly, but 
that support permit issuance or administration).
    Permit revision means any permit modification or administrative 
permit amendment.
    Permitting authority means either of the following:
    (1) The Administrator, in the case of EPA-implemented programs; or
    (2) The State air pollution control agency, local agency, other 
State agency, or other agency authorized by the Administrator to carry 
out a permit program under this part.
    Potential to emit means the maximum capacity of a stationary source 
to emit any air pollutant under its physical and operational design. Any 
physical or operational limitation on the capacity of a source to emit 
an air 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 is enforceable by the Administrator. This term does 
not alter or affect the use of this term for any other purposes under 
the Act, or the term ``capacity factor'' as 
used in title IV of the Act or the regulations promulgated thereunder.
    Proposed permit means the version of a permit that the permitting 
authority proposes to issue and forwards to the Administrator for review 
in compliance with Sec. 70.8.
    Regulated air pollutant means the following:
    (1) Nitrogen oxides or any volatile organic compounds;
    (2) Any pollutant for which a national ambient air quality standard 
has been promulgated;
    (3) Any pollutant that is subject to any standard promulgated under 
section 111 of the Act;
    (4) Any Class I or II substance subject to a standard promulgated 
under or established by title VI of the Act; or
    (5) Any pollutant subject to a standard promulgated under section 
112 or other requirements established under section 112 of the Act, 
including sections 112(g), (j), and (r) of the Act, including the 
following:
    (i) Any pollutant subject to requirements under section 112(j) of 
the Act. If the Administrator fails to promulgate a standard by the date 
established pursuant to section 112(e) of the Act, any pollutant for 
which a subject source would be major shall be considered to be 
regulated on the date 18 months after the applicable date established 
pursuant to section 112(e) of the Act; and
    (ii) Any pollutant for which the requirements of section 112(g)(2) 
of the Act have been met, but only with respect to the individual source 
subject to section 112(g)(2) requirement.
    Regulated pollutant (for presumptive fee calculation), which is used 
only for purposes of Sec. 70.9(b)(2), means any 
``regulated air pollutant'' except the 
following:
    (1) Carbon monoxide;
    (2) Any pollutant that is a regulated air pollutant solely because 
it is a Class I or II substance to a standard promulgated under or 
established by title VI of the Act; or
    (3) Any pollutant that is a regulated air pollutant solely because 
it is subject to a standard or regulation under section 112(r) of the 
Act.
    Renewal means the process by which a permit is reissued at the end 
of its term.
    Responsible official means one of the following:
    (1) For a corporation: a president, secretary, treasurer, or vice-
president of the corporation in charge of a principal business function, 
or any other person who performs similar policy or decision-making 
functions for the corporation, or a duly authorized representative of 
such person if the representative is responsible for the overall 
operation of one or more manufacturing, production, or operating 
facilities applying for or subject to a permit and either:
    (i) The facilities employ more than 250 persons or have gross annual 
sales or expenditures exceeding $25 million (in second quarter 1980 
dollars); or
    (ii) The delegation of authority to such representatives is approved 
in advance by the permitting authority;
    (2) For a partnership or sole proprietorship: a general partner or 
the proprietor, respectively;

[[Page 211]]

    (3) For a municipality, State, Federal, or other public agency: 
Either a principal executive officer or ranking elected official. For 
the purposes of this part, a principal executive officer of a Federal 
agency includes the chief executive officer having responsibility for 
the overall operations of a principal geographic unit of the agency 
(e.g., a Regional Administrator of EPA); or
    (4) For affected sources:
    (i) The designated representative in so far as actions, standards, 
requirements, or prohibitions under title IV of the Act or the 
regulations promulgated thereunder are concerned; and
    (ii) The designated representative for any other purposes under part 
70.
    Section 502(b)(10) changes are changes that contravene an express 
permit term. Such changes do not include changes that would violate 
applicable requirements or contravene federally enforceable permit terms 
and conditions that are monitoring (including test methods), 
recordkeeping, reporting, or compliance certification requirements.
    State means any non-Federal permitting authority, including any 
local agency, interstate association, or statewide program. The term 
``State'' also includes the District of 
Columbia, the Commonwealth of Puerto Rico, the Virgin Islands, Guam, 
American Samoa, and the Commonwealth of the Northern Mariana Islands. 
Where such meaning is clear from the context, 
``State'' shall have its conventional 
meaning. For purposes of the acid rain program, the term 
``State'' shall be limited to authorities 
within the 48 contiguous States and the District of Columbia as provided 
in section 402(14) of the Act.
    Stationary source means any building, structure, facility, or 
installation that emits or may emit any regulated air pollutant or any 
pollutant listed under section 112(b) of the Act.
    Whole program means a part 70 permit program, or any combination of 
partial programs, that meet all the requirements of these regulations 
and cover all the part 70 sources in the entire State. For the purposes 
of this definition, the term ``State'' does 
not include local permitting authorities, but refers only to the entire 
State, Commonwealth, or Territory.
