SAN DIEGO COUNTY AIR POLLUTION CONTROL DISTRICT

RULE 260.2 - DEFINITIONS
(Rev. Effective 11-3-92)

Terms used in this regulation shall have the following meanings or, for terms not herein defined, the meaning given them in Regulation I of the Air Pollution Control District of San Diego County or in the Act:

(a) "Act" means the Clean Air Act (42 U.S.C. 1857 et seq., as amended by Public Law 91-604, 84 Stat. 1676) and Public Law 95-95.

(b) "Administrator" means the Administrator of the Environmental Protection Agency or his authorized representative.

(c) "Affected Facility" means, with reference to a stationary source, any apparatus to which a standard is applicable.

(d) "Alternative Method" means any method of sampling and analyzing for an air pollutant which is not a reference or equivalent method but which has been demonstrated to the Administrator's satisfaction to, in specific cases, produce results adequate for his determination of compliance.

(e) "Capital Expenditure" means an expenditure for a physical or operational change to an existing facility which exceeds the product of the applicable "annual asset guideline repair allowance percentage" specified in the latest edition of Internal Revenue Service Publication 534 and the existing facility's basis, as defined by Section 1012 of the Internal Revenue Code. However, the total expenditure for a physical or operational change to an existing facility must not be reduced by any "excluded additions" as defined in IRS Publication 534, as would be done for tax purposes.

(f) "Commenced" means, with respect to the definition of "new source" in Section 111 (a)(2) of the Act, that an owner or operator has undertaken a continuous program of construction, reconstruction, or modification or that an owner or operator has entered into a contractual obligation to undertake and complete, within a reasonable time, a continuous program of construction, reconstruction, or modification.

(g) "Construction" means fabrication, erection, or installation of an affected facility.

(h) "Continuous Monitoring System" means the total equipment, required under the emission monitoring sections in applicable subparts, used to sample and condition (if applicable), to analyze, and to provide a permanent record of emissions or process parameters.

(i) "Equivalent Method" means any method of sampling and analyzing for an air pollutant which has been demonstrated to the Administrator's satisfaction to have a consistent and quantitatively known relationship to the reference method, under specified conditions.

(j) "Excess Emissions and Monitoring Systems Performance Report" is a report that must be submitted periodically by a source in order to provide data on its compliance with stated emission limits and operating parameters, and on the performance of its monitoring systems.

(k) "Existing Facility" means, with reference to a stationary source, any apparatus of the type for which a standard is promulgated in this regulation, and the construction, reconstruction, or modification of which was commenced before the date of proposal of that standard in the Federal Register; or any apparatus which could be altered in such a way as to be of that type.

(l) [Reserved]

(m) "Isokinetic Sampling" means sampling in which the linear velocity of the gas entering the sampling nozzle is equal to that of the undisturbed gas stream at the sample point.

(n) "Malfunction" means any sudden and unavoidable 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.

(o) "Modification" means any physical change in, or change in the method of operation of, an existing facility which increases the amount of any air pollutant (to which a standard applies) emitted into the atmosphere by that facility or which results in the emission of any air pollutant (to which a standard applies) into the atmosphere not previously emitted.

(p) "Monitoring Device" means the total equipment, required under the monitoring of operations rules in applicable subparts, used to measure and record (if applicable) process parameters.

(q) "Nitrogen Oxides" means all oxides of nitrogen except nitrous oxide, as measured by test methods set forth in this regulation.

(r) "One-Hour Period", with respect to continuous monitoring systems, means any 60-minute period commencing on the hour.

(s) "Opacity" means the degree to which emissions reduce the transmission of light and obscure the view of an object in the background.

(t) "Owner or Operator" means any person who owns, leases, operates, controls, or supervises an affected facility or a stationary source of which an affected facility is a part.

(u) "Particulate Matter" means any finely divided solid or liquid material, other than uncombined water, as measured by the referenced methods specified under each applicable subpart, or an equivalent or alternative method.

(v) "Proportional Sampling" means sampling at a rate that produces a constant ratio of sampling rate to stack gas flow rate.

(w) "Reference Method" means any method of sampling and analyzing for an air pollutant as described in Appendix A to 40 CFR Part 60.

(x) "Run" means the net period of time during which an emission sample is collected. Unless otherwise specified, a run may be either intermittent or continuous within the limits of good engineering practice.

(y) "Shutdown" means the cessation of operation of an affected facility for any purpose.

(z) "Six-Minute Period" means any one of the 10 equal parts of a one-hour period.

(aa) "Standard" means a standard of performance promulgated under this regulation.

(bb) "Startup" means the setting in operation of an affected facility for any purpose.

(cc) "Stationary Source" means any building, structure, facility, or installation which emits or may emit any air pollutant.
