(a) Is designed or used for collecting water or conveying runoff.
(b) Is not part of a combined sewer system.
(c) Is not draining to a storm water treatment device or system, i.e. a treatment plant designed for the purpose of treating storm water.
(d) Discharges directly or indirectly to waters of the state.
(29) Site means the entire area included in the legal description of the land on which the land disturbing construction activity is proposed in the permit application.
(30) Stop work order means an order issued by the Director of Public Works or his designee which requires that all construction activity on the site be stopped.
(31) Technical standard means a document that specifies design, predicted performance and operation and maintenance specifications for a material, device or method.
(32) Type II distribution means a rainfall type curve as established in the "United States Department of Agriculture, Soil Conservation Service), Technical Paper 149, published 1973". The Type II curve is applicable to all of Wisconsin and represents the most intense storm pattern.
(33) Waters of the state has the meaning given in s. 281.01 (18), Wis. Stats.
