(2) "Borrow site" means an area outside of a project site from which stone, soil, sand or gravel is excavated for use at the project site, except the term does not include commercial pits.
(3) "Construction" or "maintenance" includes clearing and grubbing, demolition, excavating, pit trench dewatering, filling or grading.
(4) "Contractor" means a prime contractor and any subcontractor of the prime contractor.
(5) "Corrective action" means action that is taken in response to a discharge, or to the threat of a discharge, to minimize or prevent the discharge. "Corrective action" may include preventative maintenance of existing best management practices, or the implementation of new or different best management practices.
(6) "Department" means the Wisconsin department of transportation.
(7) "Design storm" means a hypothetical discrete rainstorm characterized by a specific duration, temporal distribution, rainfall intensity, return frequency and total depth of rainfall.
(7m) "Directed and supervised by the department" means any of the following:
(a) An activity undertaken under a bid let by the department, unless the department let the bid at the request of a city, village, town or county to assist with a transportation facility that is or will be under the jurisdiction of that city, village, town or county, and the bid specifies either that this chapter does not apply or that the activity is subject to regulation by the department of natural resources.
(b) An activity undertaken under a contract to which the department is a party, unless the contract specifies that this chapter does not apply and the department did not let the bid for that activity.
(c) An activity undertaken using funds awarded by the department under a grant agreement that specifies that the department is administering the project or that this chapter applies.
(d) The construction or maintenance of any highway or portion of a highway located on a federal-aid system, unless no state or federal funds are used, or unless all state and federal funds used are awarded under a grant agreement that does not specify that the department is directing and supervising, or administering, the project.

Note: The Department of Transportation sometimes engages in the activities described in this subsection to assist local units of government on local transportation facility construction projects. Providing such assistance, without more, does not mean the Department directs and supervises that local project, and the project does not become subject to this chapter because of that assistance. Activities not directed and supervised by the Department are subject to erosion control and stormwater management regulation by the Department of Natural Resources.

(8) "Discharge" means the movement of pollutants or sediments from a project site or selected site as a result of erosion or runoff.

(14) "Infiltration system" means a device or practice that is designed specifically to encourage the entry and movement of surface water into or through underlying soil.

(15m) "Land disturbing activity" means any manmade alteration of the land surface resulting in a change in the topography or existing vegetative or non-vegetative soil cover, that may result in increased runoff and lead to an increase in soil erosion and movement of sediment into waters of the state. "Land disturbing activity" includes clearing and grubbing, demolition, excavating, pit trench dewatering, and filling and grading activities, but does not include routine maintenance. "Land disturbing activity" does not include activities, such as tree trimming or brush removal, that involve only the cutting or removing of vegetation above the ground by a utility person.
(16) "Material disposal site" means an area that is outside of a project site, is used for the lawful disposal of surplus materials or materials unsuitable for use within the project site, and is under the direct control of the contractor.
