Referred to as the Federal Water Pollution Control Act or Federal Water Pollution Control Act Amendments of 1972 and any subsequent amendments thereto.
(3) Commencement of Construction: The initial Disturbance of soils associated with clearing, grubbing, grading, and placement of fill or excavating activities or other construction activities.
(4) Comprehensive Storm Water Management Plan: The written document and plans meeting the requirements of this regulation that sets forth the plans and practices to minimize storm water runoff from a development area, to safely convey or temporarily store and release post-development runoff at an allowable rate or minimize flooding and stream bank erosion, and to protect or improve storm water quality and stream channels.
(5) Concentrated Storm Water Runoff: Any Storm Water runoff which flows through a drainage pipe, ditch, diversion or other discrete conveyance channel.
(6) Development: The carrying out of building, engineering, mining or other operations in, on, over or under land, or the making of any material change in the use of any buildings or other land.
(7) Development Area: A parcel of contiguous parcels owned by one person or persons, or operates as one development, unit and used or being developed for commercial, industrials, residential, institutional or other construction or alteration that changes runoff characteristics.

(14) Drainage: The removal of excess surface water or groundwater from land by surface of subsurface drains.
(15) Drainage Watershed: For purposes of the most current Ohio NPDES Statewide Construction Storm Water General Permit the total contributing drainage area to a BMP/SCM, i.e., the "watershed" directed to the practice. This would also include any off-site drainage.
(16) Erosion: The process by which the land surface is worn away by the action of wind, water, ice, gravity, or any combination of these forces.
(17) Extended Detention Facility: A storm water control measure that replaces and/or enhances traditional detention facilities by releasing the runoff collected during the storm water quality event over at least 24 to 48 hours, retarding flow and allowing pollutants to settle within the facility.
(18) Final Stabilization: means that either:
(A) All soil disturbing activities at the site are complete and a uniform perennial vegetative cover (e.g. evenly distributed, without large bare areas) with a density of at least 80 percent cover for the area has been established on all unpaved areas and areas not covered by permanent structures or equivalent stabilization measures (such as the use of landscape mulches, rip-rap, gabions, or geotextiles) have been employed. In addition, all temporary erosion and sediment control practices are removed and disposed of and all trapped sediment is permanently stabilized to prevent further erosion; or
(B) For individual lots in residential construction by either:
a. The homebuilder completing Final Stabilization as specified above or
b. The homebuilder establishing Temporary Stabilization including perimeter controls for an individual lot prior to occupation of the home by the homeowner and informing the homeowner of the need for and benefits of, Final Stabilization. (Homeowners typically have an incentive to put in the landscaping functionally equivalent to Final Stabilization as quick as possible to keep mud out of their homes and off sidewalks and driveways); or
(C) For construction projects on land used for agricultural purposes (e.g. pipelines across crop or range land), Final Stabilization may be accomplished by returning the disturbed land to its pre-construction agricultural use. Areas disturbed that were previously used for agricultural activities, such as buffer strips immediately adjacent to Surface Waters of the State and which are not being returned to their pre-construction agricultural use, must meet the Final Stabilization criteria in (1) or (2) above.
