District means the Montgomery Soil Conservation District.
Drainage area means the area contributing runoff to a single point measured in a horizontal plane that is enclosed by a ridge line.
Environmental site design means the use of small-scale stormwater management practices, nonstructural techniques, and better site planning to mimic natural hydrologic runoff characteristics and minimize the impact of land development on water resources.
Erosion means the process by which the ground surface is worn by the action of the wind, water, ice, gravity, or artificial means.

Erosion and sediment control plan means an erosion and sediment control strategy or plan designed to minimize erosion and off-site sedimentation.
Excavating means any act by which soil, earth, sand, gravel, rock, or any similar material is cut into, dug, quarried, uncovered, removed, displaced, relocated, or bulldozed, and includes the conditions that result from that act.
Filling means any act by which soil, earth, sand, gravel, rock, or any similar material is deposited, placed, pushed, pulled, or transported, and includes the conditions that result from that act.
Final erosion and sediment control plan means, along with the final stormwater management plan, the last of 3 plans submitted under the comprehensive review and approval process required by state law. A final erosion and sediment control plan must be prepared and approved as required by the Department and this Chapter and designed under state Standards and Specifications.
Finished grade means the final grade or elevation of the ground surface conforming to the approved grading plan.
Grading mean an act by which soil is cleared, stripped, stockpiled, or any combination thereof.
Grading unit means the maximum contiguous area allowed to be graded at a given time. For this Chapter, a grading unit is 20 acres or less.

Inspection agency means the Administration or, if delegated enforcement authority, the Department.
Land-disturbing activity means any earth movement and land changes which may result in soil erosion from water or wind or the movement of sediments into state waters or onto lands in the state, including tilling, clearing, grading, excavating, stripping, stockpiling, filling and related activities, and the covering of land surfaces with an impermeable material.
Low-maintenance ground cover means vegetative ground cover that provides a thick, stabilizing root mat on slopes with a gradient between 3:1 and 2:1, and continues to provide that stabilization without requiring mowing or fertilization more than once each year.
Maximum extent practicable means designing a stormwater management system so that all reasonable opportunities for using environmental site design planning techniques and treatment practices are exhausted and only where absolutely necessary is a structural best management practice implemented.
Natural ground surface means the ground surface in its original state before grading, stripping, excavating or filling, or other land-disturbing activities.
Owner/Developer means a person undertaking, or for whose benefit is undertaken, any activity covered by this Chapter. Owner/Developer does not include a general contractor or subcontractor who does not have a proprietary interest in a project.
Permit means the sediment control permit issued by the Department authorizing land-disturbing activity under this Chapter.
Permittee means any person to whom a permit is issued under this Chapter.
