(ii) The term does not include coatings or finishing materials.Īdhesive bonding primer≺ primer applied in a thin film to aerospace components for the purpose of corrosion inhibition and increased adhesive bond strength by attachment.

(i) A chemical substance that is applied for the purpose of bonding two surfaces together other than by mechanical means. (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.Īctual PAL for a major facility≺ PAL based on the baseline actual emissions of all emissions units at a major facility that emit or have the potential to emit the PAL pollutant.Īdhesion promoter≺ very thin coating applied to an aerospace vehicle or component substrate to promote wetting and to form a chemical bond with the subsequently applied material. Actual emissions shall be calculated using the unit’s actual operating hours, production rates and types of materials processed, stored or combusted during the selected time period. The Department will authorize the use of a different time period upon a determination that it is more representative of normal source operation. (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.

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).

Instead, the definition of the terms ‘‘projected actual emissions’’ and ‘‘baseline actual emissions’’ apply for those purposes. 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). § § 4001≴015).Īctual emissions≿or 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. The ablative char surface serves as an insulating barrier, protecting adjacent components from the heat or open flame.Īccount—The place in the NO x allowance tracking system where allowances are recorded including allowances held by a NO x affected source.Īccount number—The identification number given by the NO x budget administrator to an account in which NO x allowances are held in the NO x allowance tracking system.Īcquiring account—The party in a NO x allowance transfer who obtains NO x allowances through purchase, trade, auction, gift or another lawful means.Īct—The Air Pollution Control Act (35 P. In addition, the following words and terms, when used in this article, have the following meanings, unless the context clearly indicates otherwise:ĪBS welding adhesive or acrylonitrile-butadiene-styrene welding adhesive— An adhesive intended by the manufacturer to weld acrylonitrile-butadiene-styrene (ABS) pipe, which is made by reacting monomers of acrylonitrile, butadiene and styrene.Īblative coating≺ coating that chars when exposed to open flame or extreme temperatures, as would occur during the failure of an engine casing or during aerodynamic heating. The definitions in section 3 of the act (35 P.S.
