ACCEPTABLE EROSION AND SEDIMENT CONTROL PROGRAM. The activities of a county or local enforcing agency or authorized public agency that are conducted in accordance with the rules and part 91 (M.C.L.A. §§ 324.9101 et seq.) regarding staff training, developing and reviewing plans, issuing permits, conducting inspections and initiating compliance and enforcement actions to effectively minimize erosion and off-site sedimentation.
AUTHORIZED PUBLIC AGENCY. A state agency or an agency of a local unit of government authorized under § 9110 of part 91 (M.C.L.A. §§ 324.9101 et seq.) to implement soil erosion and sedimentation control procedures with regard to earth changes undertaken by it.

CITY ENGINEER. The City Engineer of the city or his or her duly authorized and designated representative in the Department of Engineering and Building.
EARTH CHANGE. A human-made change in the natural cover or topography of land, including cut and fill activities, which may result in or contribute to soil erosion or sedimentation of the waters of the state. EARTH CHANGE does not include the practice of plowing and filling for crop production.
EROSION. The process by which the ground surface is worn away by action of wind, water, gravity or a combination thereof.
EXCAVATION or CUT. Any act by which soil is cut into, dug, uncovered, removed, displaced or relocated, and shall include the conditions resulting therefrom.
FLOODPLAIN. The area which would be inundated by storm run-off or flood water equivalent to that which would occur with a rainfall or flood of 100-year recurrence frequency after total development of the watershed.
GRADING. Any stripping, excavating, filling, stockpiling, or any combination thereof, and shall include the land in its excavated or filled condition.
LAKE. The Great Lakes and all natural and artificial inland lakes or impoundments that have definite banks, a bed, visible evidence of a continued occurrence of water and a surface area of water that is equal to, or greater than, one acre. LAKE does not include sediment basins and basins constructed for the sole purpose of storm water retention, cooling water or treating polluted water.
MUNICIPAL ENFORCING AGENCY. The City of Wyandotte Department of Engineering and Building.
NON-EROSIVE VELOCITY. The surface water velocity which is not conducive to the development of accelerated soil erosion.
PERMANENT SOIL EROSION AND SEDIMENTATION CONTROL MEASURE. Those control measures which are installed or constructed to control soil erosion and sedimentation, and which are maintained after project completion.
SEDIMENT. Any solid particulate matter, mineral or organic that has been deposited in water, is in suspension in water, is being transported or has been removed from its site of origin by the process of soil erosion and deposited elsewhere.
SOIL EROSION AND SEDIMENTATION CONTROL (SESC) PERMIT. A permit issued to authorize work to be performed under this chapter.
STABILIZATION. The proper placing, grading and/or covering of soil or rock to ensure their resistance to erosion, sliding or other movement.

STRIPPING. Any activity which removes or significantly disturbs the vegetative surface cover, including clearing and grubbing operations.
TEMPORARY SOIL EROSION AND SEDIMENTATION CONTROL MEASURES. Interim control measures which are installed or constructed to control soil erosion and sedimentation and are not maintained after project completion.
