29 C.F.R. § 780.703
The basic requirements for exemption of country elevator employees under section 13(b)(14) of the Act are as follows:
(a) The employing establishment must:
(b) The employee must:
(2) Be employed “within the area of production,” as defined by the Secretary of Labor.
All the requirements must be met in order for the exemption to apply to an employee in any workweek. The requirements in section 13(b)(14) are “explicit prerequisites to exemption” and the burden of showing that they are satisfied rests upon the employer who asserts that the exemption applies (Arnold v. Kanowsky, 361 U.S. 388). In accordance with the general rules stated in § 780.2 of subpart A of this part, this exemption is to be narrowly construed and applied only to those establishments plainly and unmistakably within its terms and spirit. The requirements for its application will be separately discussed below.
