As used in this chapter, the following terms shall have the meanings
indicated:
Any formation of soil, sand, rock, gravel, limestone, sandstone,
or other material, or any crevice from which underground water is or may be
produced.
A conservation or pollution control practice that manages wastes,
agricultural chemicals, or hazardous materials so as to minimize movement
into surface or ground waters within the Wellhead Protection District.
A device that is designed to contain an unauthorized release, retain
it for cleanup, and prevent released materials from penetrating into the ground.
The United States Environmental Protection Agency.
A permit meeting the requirements of the National Pollutant Discharge
Elimination System Permit Application Regulations for Storm Water Discharges
issued by the EPA on November 16, 1990.
Any substance that: (1) conveys toxic, lethal, or other injurious
effects or which causes sublethal alterations to plant, animal, or aquatic
life; or (2) may be injurious to human beings. Hazardous materials include
any matter identified as a "hazardous waste" by the Environmental Protection
Agency or a "controlled hazardous substance" by the Maryland Department of
the Environment.
Any surface that prevents the percolation of water into the ground.
The Maryland Department of the Environment.
A plan prepared by a certified nutrient management consultant to
manage the amount, placement, timing, and application of animal waste, fertilizer,
sewage sludge, and other plant nutrients in order to prevent pollution and
to maintain productivity of the soil.
Drains which are not connected to municipal sewer or stormwater systems
and which discharge directly to the ground or septic system.
A property owner or his duly authorized agent or attorney, a purchaser,
devisee, fiduciary, and any other person having a vested or contingent interest
in the property in question.
Any natural person, individual, public or private corporation, firm,
association, joint venture, partnership, municipality, government agency,
political subdivision, public officer, owner, lessee, tenant, or any other
entity whatsoever or any combination of such, jointly or severally.
Any substance or mixture of substances intended for:
Official publications of MDE with standards and requirements for
protection of groundwater resources.
A bored, drilled, driven or dug well whose depth is greater than
the largest surface dimension, through which fluids enter the subsurface;
or an improved sinkhole; or a subsurface fluid distribution system.
An underground storage tank, connected piping, underground ancillary
equipment, and containment system, if any.
That land area overlying the aquifer which contributes water to a
public water supply well under the permitted withdrawal rate (average annual)
and average annual recharge conditions that can be anticipated based on historical
data. It is bounded and may be influenced by the groundwater divides which
result from pumping the well and by the contact of the aquifer with less permeable
geologic boundaries. In all cases, the Wellhead Protection District shall
extend upgradient to its point of intersection with prevailing hydrogeologic
boundaries (a groundwater flow divide, a contact with geologic formations,
or a recharge boundary), or be limited by time of travel. The Wellhead Protection
District shall be reviewed and approved by MDE. The Wellhead Protection District
shall include a minimum of two zones of protection, with Zone 1 being the
most restrictive. Zone 1 is based on a one-year time of travel, fixed radius
or other assessment of an area most closely connected to the water supply.
Zone 2 is based on a ten-year time of travel or by hydrogeologic boundaries.
The boundary of Zone 3, when delineated, encompasses the total land area that
is determined to provide recharge to a public water supply well. (Note: A
twenty- or twenty-five-year time of travel may be used to mark the edge of
Zone 2, if numerical modeling with particle tracking is used to delineate
the wellhead protection area.)
A pen or other outdoor area used for the feeding and care of livestock
or poultry.
