Definitions.
AQUIFER
A geologic formation composed of rock, sand or gravel that contains significant amounts of potentially recoverable water.
GA1
"GA1" as defined in RSA 485-C:5,1; namely, "groundwater in a defined zone of high value for present or future drinking water supply."
GA2
"GA2" as defined in RSA 485-C:5,I; namely, "groundwater within aquifers identified as highly productive for potential use as a public water supply by the U.S. Geological Survey regional groundwater studies, or other regional studies."
GAA
"GAA" as defined in RSA 485-C:5,I; namely, "groundwater in this class is within the wellhead protection area for wells which presently are used or well sites which have been identified for future use as drinking water supply for public water systems."
GASOLINE STATION
That portion of a property where petroleum products are received by tank vessel, pipeline, tank car, or tank vehicle and distributed for the purposes of retail sale of gasoline.
GROUNDWATER
Subsurface water that occurs beneath the water table in soils and geologic formations.
IMPERVIOUS
Not readily permitting the infiltration of water.
IMPERVIOUS SURFACE
A surface through which regulated substances cannot pass when spilled. Impervious surfaces include concrete unless unsealed cracks or holes are present. Asphalt; earthen, wooden, or gravel surfaces; or other surfaces which could react with or dissolve when in contact with the substances stored on them are not considered impervious for the express purpose of retaining the regulated substances; however, these surfaces are considered impervious for the calculation of stormwater impacts and other regulatory calculations separate from the retention of spills. (03/2024)
JUNKYARD
An establishment or place of business which is maintained, operated, or used for storing, keeping, buying, or selling junk, or for the maintenance or operation of an automotive recycling yard, and includes garbage dumps and sanitary landfills. The word does not include any motor vehicle dealers registered with the Director of Motor Vehicles under RSA 261:104 and controlled under RSA 236:126.
OUTDOOR STORAGE
Storage of materials where they are not protected from the elements by a roof, walls, and a floor with a surface impervious to regulated substances. (03/2024)
PETROLEUM BULK PLANT or TERMINAL
Means that portion of the property where petroleum products are received by tank vessel, pipeline, tank car, or tank vehicle and are stored or blended in bulk for the purpose of distributing such liquids by tank vessel, pipeline tank car, tank vehicle, portable tank, or container.
PUBLIC WATER SYSTEM
A system for the provision to the public of piped water for human consumption, if such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year.
REGULATED SUBSTANCE
Petroleum, petroleum products, and substances listed under 40 CFR 302, 7-1-05 edition, excluding the following substances: (1) ammonia, (2) sodium hypochlorite, (3) sodium hydroxide, (4) acetic acid, (5) sulfuric acid, (6) potassium hydroxide, (7) potassium permanganate, and (8) propane and other liquefied fuels which exist as gases at normal atmospheric temperature and pressure.
SANITARY PROTECTIVE RADIUS
The area around a well which must be maintained in its natural state as required by Env-Dw 301 or Env-Dw 302 (for community water systems) and Env-Ws 373.12 and Env-Ws 372.14 (for other public water systems).[1]
SECONDARY CONTAINMENT
A structure such as a berm or dike with surface impervious to regulated substances which is adequate to hold at least 110% of the volume of the largest regulated substance container that will be stored there. (03/2024)
SNOW DUMP
For the purposes of this ordinance, a location where snow which is cleared from roadways and/or motor vehicle parking areas is placed for disposal.
SOURCEWATER
Groundwater or surface water, in its natural state, prior to any treatment for drinking.
STRATIFIED DRIFT AQUIFER
A geologic formation of predominantly well-sorted sediment deposited by or in bodies of glacial melt water, including gravel, sand, silt, or clay, which contains sufficient saturated permeable material to yield significant quantities of water to wells.
SURFACE WATER
Streams, lakes, ponds and tidal waters, including marshes, water courses and other bodies of water, natural or artificial.
WELLHEAD PROTECTION AREA
The surface and subsurface area surrounding a water well or well field supplying a community public water system, through which contaminants are reasonably likely to move toward and reach such water well or well field.
WETLAND BUFFER
"Wetland buffer" or "wetland setback" means a designated area contiguous or adjacent to a wetland that is required for the continued maintenance, function, and stability of the wetland. (03/2024)
