Definitions.
ALTERATION OF DRAINAGE CHARACTERISTICS:Any activity on an area of land that changes the water quality, force, direction, timing or location of runoff flowing from the area. Such changes include: change from distributed runoff to confined, discrete discharge, change in the volume of runoff from the area; change in the peak rate of runoff from the area; and change in the recharge to groundwater on the area.
BEST MANAGEMENT PRACTICE (BMP):An activity, procedure, restraint, or structural improvement that helps to reduce the quantity or improve the quality of storm water runoff.
CLEARING:Any activity that removes the vegetative surface cover.
DEVELOPMENT:The modification of land to accommodate a new use or expansion of use, usually involving construction.
DISTURBANCE OF LAND:Any action that causes a change in the position, location, or arrangement of soil, sand rock, gravel of similar earth material.
GRADING:Changing the level or shape of the ground surface.
GRUBBING:The act of clearing land surface by digging up roots and stumps.
IMPERVIOUS SURFACE:Any material or structure on or above the ground that prevents water infiltrating the underlying soil. Impervious surface includes without limitation roads, paved parking lots, sidewalks, and roof tops.
MASSACHUSETTS STORMWATER MANAGEMENT POLICY:The Policy issued by the Department of Environmental Protection, and as amended, that coordinates the requirements prescribed by state regulations promulgated under the authority of the Massachusetts Wetlands Protection Act G.L. c. 131 §
40 and Massachusetts Clean Waters Act G.L. c. 21, §. 23-56. The Policy addresses storm water impacts through implementation of performance standards to reduce or prevent pollutants from reaching water bodies and control the quantity of runoff from a site.
MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4) or MUNICIPAL STORM DRAIN SYSTEM:The system of conveyances designed or used for collecting or conveying storm water, including any road with a drainage system, street, gutter, curb, inlet, piped storm drain, pumping facility, retention or detention basin, natural or man-made or altered drainage channel, reservoir, and other drainage structure that together comprise the storm drainage system owned or operated by the city of Everett.
OPERATION AND MAINTENANCE PLAN:A plan setting up the functional, financial and organizational mechanisms for the ongoing operation and maintenance of a storm water management system to insure that it continues to function as designed.
OUTFALL:The point at which storm water flows out from a point source discernible, confined and discrete conveyance into waters of the Commonwealth.
OUTSTANDING RESOURCE WATERS (ORWs):Waters designated by Massachusetts Department of Environmental Protection as ORWs. These waters have exceptional sociologic, recreational, ecological and/or aesthetic values and are subject to more stringent requirements under both the Massachusetts Water Quality Standards (314 CMR 4.00) and the Massachusetts Storm water Management Standards. ORWs include vernal pools certified by the Natural Heritage Program of the Massachusetts Department of Fisheries and Wildlife and Environmental Law Enforcement, all Class A designated public water supplies with their bordering vegetated wetlands, and other waters specifically designated.
OWNER:A person with a legal or equitable interest in property.
PERSON:An individual, partnership, association, firm, company, trust, corporation, agency, authority, department or political subdivision of the Commonwealth or the federal government, to the extent permitted by law, and any officer, employee, or agent of such person.
POINT SOURCE:Any discernible, confined, and discrete conveyance, including but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, or container from which pollutants are or may be discharged.
REDEVELOPMENT:Development, rehabilitation, expansion, demolition or phased projects that disturb the ground surface or increase the impervious area on previously developed sites.
RUNOFF:Rainfall, snowmelt, or irrigation water flowing over the ground surface.
STORMWATER:Storm water runoff, snow melt runoff, and surface water runoff and drainage.
TSS:Total Suspended Solids.
