Under section 7(b)(3) of the Act, the intent of the exemption must be given effect in determining the scope of its application to an enterprise and to the employees of an enterprise. The statutory language must be applied to the facts in a manner consistent with the purpose of the exemption as evidenced by its legislative history. This purpose is to relieve the described enterprises from the application of the Act's general overtime pay requirements (in the limited manner specified in the exemption) to employment in their activities of distributing petroleum products. Such employment was stated to be affected by climatic, seasonal, and other pertinent factors characteristic of business operations in the distribution of such products.
