This regulation reads: <br /> "Upon application to the Huerfano County Code Enforcement Officer a temporary use <br /> permit may be issued for the following uses, as shown in Table 3, below, in the following <br /> zoning districts and for the following periods of time. Such permits shall be valid only for <br /> the period of time specified and no more than two renewals of the temporary permit shall <br /> be issued by the County Code Enforcement Officer. " <br /> Therefore, an application for temporary asphalt and concrete plants will be filed with the <br /> Huerfano County Code Enforcement Officer for project based temporary use of portable plants. <br /> Approval of such applications will be submitted to the Division prior to use of concrete and <br /> asphalt plants on site. <br /> 15.
