PART 63--NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES--Table of Contents
 
    Subpart D--Regulations Governing Compliance Extensions for Early 
                 Reductions of Hazardous Air Pollutants
 
Sec. 63.71  Definitions.

    All terms used in this subpart not defined in this section are given 
the same meaning as in the Act.
    Act means the Clean Air Act as amended.
    Actual emissions means the actual rate of emissions of a pollutant, 
but does not include excess emissions from a malfunction, or startups 
and shutdowns associated with a malfunction. Actual emissions shall be 
calculated using the source's actual operating rates, and types of 
materials processed, stored, or combusted during the selected time 
period.
    Artificially or substantially greater emissions means abnormally 
high emissions such as could be caused by equipment malfunctions, 
accidents, unusually high production or operating rates compared to 
historical rates, or other unusual circumstances.
    EPA conditional method means any method of sampling and analyzing 
for air pollutants that has been validated by the Administrator but that 
has not been published as an EPA Reference Method.
    EPA reference method means any method of sampling and analyzing for

an air pollutant as described in appendix A of part 60 of this chapter, 
appendix B of part 61 of this chapter, or appendix A of part 63.
    Equipment leaks means leaks from pumps, compressors, pressure relief 
devices, sampling connection systems, open-ended valves or lines, 
valves, connectors, agitators, accumulator vessels, and instrumentation 
systems in hazardous air pollutant service.
    Existing source means any source as defined in Sec. 63.72, the 
construction or reconstruction of which commenced prior to proposal of 
an applicable section 112(d) standard.
    Hazardous air pollutant (HAP) means any air pollutant listed 
pursuant to section 112(b) of the Act.
    High-risk pollutant means a hazardous air pollutant listed in Table 
1 of Sec. 63.74.
    Malfunction means any sudden failure of air pollution control 
equipment or process equipment or of a process to operate in a normal or 
usual manner. Failures that are caused entirely or in part by poor 
maintenance, careless operation, or any other preventable upset 
condition or preventable equipment breakdown shall not be considered 
malfunctions.
    Not feasible to prescribe or enforce a numerical emission limitation 
means a situation in which the Administrator or a State determines that 
a pollutant (or stream of pollutants) listed pursuant to section 112(b) 
of the Act cannot be emitted through a conveyance designed and 
constructed to emit or capture such pollutant, or that any requirement 
for, or use of, such a conveyance would be inconsistent with any Federal 
law; or the application of measurement technology to a particular source 
is not practicable due to technological or economic limitations.
    Permitting authority means either a State agency with an approved 
permitting program under Title V of the Act or the Administrator in 
cases where the State does not have an approved permitting program.
    Post-reduction year means the one year period beginning with the 
date early reductions have to be achieved to qualify for a compliance 
extension under subpart D of this part, unless a source has established 
with the permitting authority an earlier one year period as the post-
reduction year. For most sources, the post-reduction year would begin 
with the date of proposal of the first section 112(d) standard 
applicable to the early reductions source; however, for sources that 
have made enforceable commitments, it would be the year from January 1, 
1994, through December 31, 1994.
    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 representative is approved 
in advance by the permitting authority.
    (2) For a partnership or sole proprietorship, a general partner or 
the proprietor, respectively.
    (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., Regional Administrators of EPA).
    Reviewing agency means a State agency with an approved permitting 
program under Title V of the Act. An EPA Regional Office is the 
reviewing agency where the State does not have such an approved 
permitting program.
    State means a State or local air pollution control agency.
