Integral part
(4) Integral part. In order to qualify for the credit, property (other than tangible personal property and research or storage facilities used in connection with any of the activities specified in subparagraph (1) of this paragraph) must be used as an integral part of one or more of the activities specified in subparagraph (1) of this paragraph. Property such as pavements, parking areas, inherently permanent advertising displays or inherently permanent outdoor lighting facilities, or swimming pools, although used in the operation of a business, ordinarily is not used as an integral part of any of such specified activities. Property is used as an integral part of one of the specified activities if it is used directly in the activity and is essential to the completeness of the activity. Thus, for example, in determining whether property is used as an integral part of manufacturing, all properties used by the taxpayer in acquiring or transporting raw materials or supplies to the point where the actual processing commences (such as docks, railroad tracks and bridges), or in processing raw materials into the taxpayer's final product, would be considered as property used as an integral part of manufacturing. Specific examples of property which normally would be used as an integral part of one of the specified activities are blast furnaces, oil and gas pipelines, railroad tracks and signals, telephone poles, broadcasting towers, oil derricks, and fences used to confine livestock. Property shall be considered used as an integral part of one of the specified activities if so used either by the owner of the property or by the lessee of the property. (5) Research or storage facilities. (i) If property (other than a building and its structural components) constitutes a research or storage facility and if it is used in connection with an activity specified in subparagraph (1) of this paragraph, such property may qualify as section 38 property even though it is not used as an integral part of such activity. Examples of research facilities include wind tunnels and test stands. Examples of storage facilities include oil and gas storage tanks and grain storage bins. Although a research or storage facility must be used in connection with, for example, a manufacturing process, the taxpayer-owner of such facility need not be engaged in the manufacturing process. (ii) In the case of property described in section 50, property will constitute a storage facility only if the facility is used principally for the bulk storage of fungible commodities. Bulk storage means the storage of a commodity in a large mass prior to its consumption or utilization. Thus, if a facility is used to store oranges that have been sorted and boxed, it is not used for bulk storage.
