RULE 33.1 - PART 70 PERMITS - DEFINITIONS (Adopted 10/12/93, Revised 4/10/01, 9/12/06, 4/12/1 1)

For the purposes of this rule the following definit ions shall apply:

1. "Acid Rain Source": Any stationary source that includes one or more emission units that are subject to emission reduction requirements or l imitations pursuant to Title IV of the

federal Clean Air Act Amendments of 1990.

2. "Administrative Part 70 Permit Amendment": A mo dification to a Part 70 permit that is being made solely for the purpose of accomplishing one or more of the following objectives:

a. Corrects typographical errors.

b. Makes an administrative change at the source suc h as the name, address or phone number of a person named in the Part 70 permit.

c. Requires more frequent monitoring or reporting b y the permittee.

d. Allows for the transfer of ownership or operatio nal control of a stationary source provided that a written agreement containing a spec ific date for transfer of Part 70 permit responsibility, coverage and liability betwe en the current and new permittee has been submitted to the District.

(Reference: 40 CFR 70.7(d)(1))

3. "Affected State": Any state:

a. Whose air quality may be affected by the issuanc e, modification or reissuance of a Part 70 permit and that is contiguous to the state of California, or

b. That is within 50 miles of the permitted source.

(Reference: 40 CFR 70.2 "Affected States")

4. "Applicable Requirement": Any federal, state, o r District air pollution requirement including any requirement promulgated pursuant to a federal implementation plan for Ventura County and all federally-enforceable requir ements.

5. "CO 2 Equivalent (CO 2 e):" The amount of greenhouse gases emitted relati ve to the global warming potential of each pollutant. CO 2 e shall be computed by multiplying the mass amount of emissions (tons per year) for each greenh ouse gas by the gas’s associated global warming potential and summing the resultant values.7/11 RULE 33.1: 2

Global warming potentials appear in Table 1 of Rule 2, Definitions.

6. "Emergency": Any situation arising from sudden and reasonably unforeseeable events beyond the control of a permittee, including acts o f God, which situation requires immediate corrective action to restore normal opera tion, and that causes the stationary source to exceed a technology-based emission limita tion under the Part 70 permit, due to

unavoidable increases in emissions attributable to the emergency. An emergency shall not include noncompliance to the extent caused by i mproperly designed equipment, lack of preventative maintenance, careless or improper o peration, or operator error. (Reference: 40 CFR 70.6(g)(1))

7. "Emissions Allowable Under the Part 70 Permit": A federally-enforceable permit condition determined at issuance to be required by an applicable requirement that establishes an emissions limit, including a work pr actice standard, or a federally enforceable emissions cap that a source has assumed to avoid an applicable requirement to which the source would otherwise be subject. (R eference: 40 CFR 70.2 "Emissions Allowable Under the Permit")

8. "EPA Hazardous Air Pollutant": Any hazardous ai r pollutant listed pursuant to Section 112(b) of the federal Clean Air Act.

an emission limitation or standard and that indicat es that emissions (or opacity) are greater than the applicable emission limitation or standard (or less than the applicable standard in the case of a percent reduction require ment) consistent with any averaging period specified for averaging the results of the m onitoring.

10. “Excursion” A departure from an indicator or s urrogate parameter range established for monitoring under the applicable requirement or Part 70 permit condition, consistent with any averaging period specified for averaging the re sults of the monitoring.

the Administrator of the EPA and citizens under the federal Clean Air Act.

12. "Federally-Enforceable Requirement": Any air p ollution requirement set forth in, or authorized by, the federal Clean Air A ct or EPA regulations.

the federal Clean Air Act and 40 CFR Part 70. This Part 70 permit shall also serve as a permit to operate issued to fulfill the requirement s of Rule 10.B. Notwithstanding the previous sentence a general Part 70 permit shall no t serve as a permit to operate issued to fulfill the requirements of Rule 10.B.

19. "Potential to Emit": The potential to emit for a stationary source is the sum of the potential to emit from all emissions units at the s tationary source. If two or more EPA hazardous air pollutants are emitted from a station ary source, the potential to emit of each EPA hazardous air pollutant that is emitted shall b e summed for the purpose of determining applicability pursuant to Rule 33.B.3.b . Notwithstanding the previous sentence, for the purpose of determining applicabil ity pursuant to Rule 33.B.3, EPA hazardous air pollutant emissions from any oil or g as exploration or production well and associated equipment, and from any pipeline compres sor or pump station shall not be aggregated with such emissions from other similar u nits whether or not such units are located in a contiguous area or are under common co ntrol. Fugitive emissions that are associated with a stationary source shall be includ ed in the potential to emit for the stationary source if such stationary source is spec ified in 40 CFR 70.2 "Major Source" (2)(i-xxvii). Fugitive emissions of EPA hazardous air pollutants shall be included in the potential to emit of a stationary source for the pu rpose of determining applicability pursuant to Rule 33.B.3.

The potential to emit for an emissions unit is the maximum quantity of each regulated air pollutant or EPA hazardous air pollutant that may b e emitted by the emissions unit, based on the emissions unit's physical and operational de sign. Physical and operational design shall include limitations that restrict emissions, such as hours of operation and type or amount of material combusted, stored or processed, provided such limitations are federally-enforceable. (Reference: 40 CFR 70.2 "Major Source", 70.2 "Poten tial to Emit")

to Section 111 of the federal Clean Air Act.

d. Any ozone-depleting substance specified as a Cla ss I or Class II substance pursuant to Title VI of the federal Clean Air Act.

e. Any pollutant subject to a standard or requireme nt promulgated pursuant to Section 112 of the federal Clean Air Act, including :

1) Any pollutant specified in the list of substance s pursuant to Section 112(r)

of the federal Clean Air Act shall be considered a regulated air pollutant upon promulgation of such list.

2) Any EPA hazardous air pollutant subject to a sta ndard or requirement promulgated by EPA pursuant to Section 112(d) of th e federal Clean Air Act shall be considered a regulated air pollutant u pon promulgation of the

standard or list.

3) Any EPA hazardous air pollutant for which the EP A has failed to promulgate a standard by the deadline established p ursuant to Section 112(e) of the federal Clean Air Act. Any such EPA hazardous air pollutant shall be considered a regulated air pollu tant 18 months after the

missed deadline.

4) Any EPA hazardous air pollutant subject to a Dis trict case-by-case emission limitation determination made pursuant to Section 112(g) of the federal Clean Air Act. For any case-by-case emissi on limitation determination made pursuant to Section 112(g), the EPA hazardous air pollutant shall be considered a regulated air pollu tant only for the stationary source for which such emission limitatio n determination was

made.

f. Greenhouse gases if the source has a potential t o emit of 100,000 tons per year or

more CO 2 equivalent emissions (effective July 1, 2011).
