Actual emissionsFor purposes of Chapter 127, Subchapter E (relating to new source review), the actual rate of emissions of a regulated NSR pollutant from an emissions unit shall be determined in accordance with the following subparagraphs. This definition does not apply for calculating whether a significant emissions increase has occurred, or for establishing a PAL under § 127.218 (relating to PALs). Instead, the definition of the terms projected actual emissions and baseline actual emissions apply for those purposes. This definition may not be used to calculate a baseline emissions rate under § 127.207(4) (relating to creditable emissions decrease or ERC generation and creation).
(i) Actual emissions as of a particular date must equal the average rate, in TPY, at which the unit actually emitted the regulated NSR pollutant during the consecutive 24-month period which immediately preceded the particular date and which is representative of normal source operations. The Department will authorize the use of a different time period upon a determination that it is more representative of normal source operation. Actual emissions shall be calculated using the units actual operating hours, production rates and types of materials processed, stored or combusted during the selected time period.
(ii) For an emissions unit that has not begun normal operations on the particular date, actual emissions equal the potential to emit of the unit on that date.

Notes of Decisions
While fugitive air contaminants are not excluded from the definition of particulate matter, fugitive air contaminants are not defined in terms of particulate matter only, thus neither term subsumed the other with regard to the material emitted. Department of Environmental Resources v. Locust Point Quarries, Inc., 396 A.2d 1205 (Pa. 1979).
As defined in this section, particulate matter was not distinguishable from fugitive emissions. Department of Environmental Resources v. Locust Point Quarries Inc., 367 A.2d 392 (Pa. Cmwlth. 1976).
