(Delegation Effect.: 11-8-76: Rev. Effect.: 1-13-87)

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. 7401 et seq.).

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

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

(d) "Capital Expenditure" means an expenditure for a physical or operational change to a stationary source which exceeds the product of the applicable "annual asset

guideline repair allowance percentage" specified in the latest edition of Internal Revenue Service (IRS) Publication 534 and the stationary source's basis, as defined by Section 1012 of the Internal Revenue Code. However, the total expenditure for a physical or operational change to a stationary source must be reduced by an "excluded additions" as defined for stationary sources constructed after December 31, 1981, in IRS Publication 534, as would be done for tax purposes. In addition, "annual asset guideline repair allowance" may be used even though it is excluded for tax purposes in IRS Publication 534.

(e) "Commenced" means that an owner or operator has undertaken a continuous program of construction or modification or that an owner or operator has entered into a contractural obligation to undertake and complete, within a reasonable time, a continuous program of construction or modification.
