(i) To prevent construction delays, a permittee may verbally request to use alternative materials or procedures, and the Administrator may verbally approve the request. The Administrator may approve the request if the materials or procedures specified in the issued permit cannot be obtained or accomplished and alternative materials or procedures meet the minimum design standards of this Chapter, Water Quality Rules Chapter 11, Water Quality Rules Chapter 12, Water Quality Rules Chapter 25, and Water Quality Rules Chapter 28; and
