As used in this article, the following terms shall have the meanings indicated:
AQUIFERGeologic formation composed of saturated, permeable material of rock and/or sand and gravel that contains significant amounts of potentially producible potable water.
AREA OF INFLUENCEThe area which experiences drawdown by a pumping well as plotted on a two-dimensional (map) surface, usually ellipsoidal.
CONE OF DEPRESSIONA three-dimensional conical concavity produced in a water table by a pumping well (see "area of influence" above).
EARTH REMOVAL and MINING OF LANDThe removal of geologic materials such as topsoil, sand and gravel, metallic ores, or bedrock to be crushed or used as building material.
GROUNDWATERAll the water found beneath the surface of the ground. In this article the term refers to the slowly moving subsurface water present in aquifers and recharge areas.
HAZARDOUS OR TOXIC MATERIALAny substance or combination of substances, including any liquid petroleum product, that, because of quantity, concentration or physical, chemical or infectious characteristics, poses a significant present or potential hazard to water supplies or to human health if generated or disposed of into or on any land or water in this City. Any substance deemed a "hazardous waste" in MGL c.
21C and
21E and 310 CMR
30.00, as amended, shall also be deemed a hazardous or toxic material for purposes of this article, with the exception of household quantities.
IMPERVIOUS SURFACENatural or man-made material on or above the ground that does not allow surface water to penetrate into the soil.
LIQUID AND LEACHABLE WASTESWaste materials, including nonsanitary wastewaters, solid wastes, sludge and agricultural wastes, that are capable of releasing waterborne contaminants to the surrounding environment.
NATURAL VEGETATIONLand having a well-established cover of native plants (grasses, shrubs, ground covers, trees, wildflowers, etc.), not including mowed lawn areas and artificially mulched (stones, plastic, etc.) planting beds.
OUTDOOR STORAGEAny storage that is not in a structure with roof, floor and at least three sides, all of impervious material.
PUBLIC WATER SYSTEMA system for the provision to the public of piped water for human consumption, if such a system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days of the year.
PUBLIC WELLA well providing potable water to at least 15 service connections or serving on average at least 25 individuals daily at least 60 days of the year. It shall also include wells not in active use that are maintained as a backup or emergency reserve for a public water system.
RECHARGEThe process by which water is added to the saturated zone of any aquifer either by direct infiltration of rainfall or by indirect inputs from surface sources or from adjoining subsurface sources and whether by reason of natural flow or by reason of pumping from a present or future well.
RECHARGE AREAAny area of porous, permeable geologic deposits, especially, but not exclusively, deposits of sand and gravel through which water from any source will recharge an aquifer, and including any wetland or body of surface water surrounding or adjacent to such area together with the watershed of any wetland or body of surface water adjacent to such area.
SANITARY WASTEWastewaters arising from ordinary domestic water use as from toilets, sinks and bathing facilities, etc., and containing such concentrations and types of pollutants as to be considered normal wastes.
SLUDGEThe solid, semisolid and liquid residue produced by water and sewage treatment processes or industrial process by-products as categorized as Types I, II and III by the criteria and regulations of 310 CMR
32.00.
SOLID WASTEAny solid material, putrescible or nonputrescible, combustible or noncombustible, including but not limited to garbage, rubbish, scrap material, junk, refuse, inert fill material, stumps, brush and other landscape refuse.
VERY SMALL QUANTITY GENERATORAn operation that does limited generation of hazardous materials. The threshold quantities for a very small quantity generator are set forth in 310 CMR
30.353.
