ILLICIT DISCHARGEDirect or indirect discharge to the municipal storm drainage system, that is not composed entirely of stormwater, except as exempted in §
87-4(d). The term does not include a discharge in compliance with a NPDES Stormwater Discharge Permit or a Surface Water Discharge Permit, or resulting from fire fighting activities exempted pursuant to §
87-4(d).
IMPERVIOUS SURFACEAny 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. Impervious surface also includes soils, gravel driveways, and similar surfaces with a high runoff coefficient (Rational Method), as determined by the Conservation Commission.
[Amended 5-20-2014 ATM, Art. 22]
LAND-DISTURBING ACTIVITYAny activity that causes a change in the position or location of soil, sand, rock, gravel, or similar earth material.
LOW IMPACT DEVELOPMENT (LID)A Stormwater Management approach and set of practices incorporated into development or redevelopment designs to reduce runoff and pollutant loadings in the runoff as close to its source(s) as possible that protect downstream resources from adverse degradation while minimizing the extent of clearing and maximizing groundwater recharge.
MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4) or MUNICIPAL STORM DRAIN SYSTEMThe various systems of conveyances designed or used for collecting or conveying stormwater, 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 Town of Newbury.
NPDES PHASE II REGULATED AREAThe area within Newbury identified by the U.S. Environmental Protection Agency as "Designated MS4 Area" under the NPDES Phase II Stormwater Program. See map entitled, "NPDES Phase II Stormwater Program Automatically Designated MS4 Areas, Newbury, Massachusetts" as may be amended.
NON-POINT SOURCE (NPS) POLLUTIONPollution of surface or groundwater supplies originating from land use activities and/or the atmosphere, having no well-defined point of entry.

OUTFALLThe point at which stormwater flows from a discernible, confined and discrete point source into waters of the Commonwealth.
OWNERA person with a legal or equitable interest in property.
PERSONAn 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.
