A drain closure apparatus for closing a storm drain, or other type of drain, in a fluid-tight manner so as to prevent a flow of hazardous materials into the drain. The closure member comprises a first cover member having an outside diameter and a peripheral edge which corresponds to the outside diameter and peripheral edge of an existing drain cover member covering a drain to enable seating and supporting the first cover member in the drain in place of the existing drain cover member, a second cover member in a hole provided therefor in the center of the first cover member, said second cover member having holes in the top thereof so as to permit a flow of fluid through the second cover member and into the drain, a closure member, and a threaded rod for moving the closure member between a first position and a second position as the second cover member is rotated to selectively close the drain in a fluid-tight manner.
