The following words and terms, when used in this article,
shall have the following meanings:
ABSORPTION AREA
A component of an individual or community sewage system where
liquid from a treatment tank seeps into the soil; it consists of an
aggregate-filled area containing piping for the distribution of liquid
and the soil or sand/soil combination located beneath the aggregate.
(2)
ALTERNATE ABSORPTION AREAA tested area which is reserved for possible future installation of an absorption area, if the primary absorption area is clogged or otherwise is malfunctioning.
ACT
The Pennsylvania Sewage Facilities Act (Act of January 24,
1966, P.L. 1535, as amended, 35 P.S. § 750.1 et seq.).
CARBONATE GEOLOGY AREA
An area where the underlying rock is formed by the organic
and inorganic precipitation of mineral compounds characterized by
the fundamental chemical ion CO
3, e.g., limestone
and dolomite.
[Amended 11-15-1995 by Ord. No. 95-5]
(1)
For application of the requirements of this
article, Carbonate Geology Areas shall be any area identified upon
the Township Zoning Map as a "Carbonate Geology Area." The designated carbonate areas were derived from Open
File Report 8702, entitled "Sinkholes and Karst Related Features of
Northampton County, Pennsylvania," by William E. Kochanov, Commonwealth
of Pennsylvania, Department of Environmental Protection, Bureau of
Topographic and Geologic Survey.
(2)
The delineation of geologic contacts is frequently
made by inference based upon interpretation of topographic features
or other field data in the absence of outcrops. Therefore, these requirements
shall apply to any development within 500 feet of the boundaries shown
for the Carbonate Geology Area.
CAVERN
A subterranean cavity or cave produced by dissolution of
limestone or dolomite.
CLOSED DEPRESSION
Remnants of sinkholes that have partially filled with soil
by erosion and settlement of the sinkhole walls. Generally, they are
found as shallow, dish-shaped depressions on the land surface in areas
of carbonate geologic formations.
COMMUNITY SEWAGE SYSTEM
Any system, whether publicly or privately owned, for the
collection of sewage or industrial wastes of a liquid nature from
two or more lots, and the treatment and/or disposal of the sewage
or industrial waste on one or more of the lots or at any other site.
DEPARTMENT
The Department of Environmental Protection of the Commonwealth
of Pennsylvania.
FRACTURE TRACES
Linear topographic depressions or lines of depressions less
than one mile in length revealing faults, joints or fissures in the
bedrock. These linear features are characterized by increased permeability,
along which the solution of carbonate rocks is intensified and hence
along which groundwater movement is concentrated. These linear features
are characterized by intensified and hence along which groundwater
movement is concentrated.
GHOST LAKES
Small bodies of water which occur in and occasionally around
closed depressions or sinkholes after periods of heavy precipitation.
They may form from slow permeability of soils, rises in the groundwater
table or from the creation of a natural liner of impermeable or slowly
permeable clays or soils in the depression.
INDIVIDUAL SEWAGE SYSTEM
A system of piping, tanks or other facilities serving a single
lot and collecting and disposing of sewage in whole or in part into
the soil or into any waters of this commonwealth or by means of conveyance
to another site for final disposal.
LINEAMENTS
Linear topographic depressions or lines of depression longer
than one mile in length, revealing faults, joints or fissures in the
bedrock. These linear features are characterized by increased permeability,
along which the solution of carbonate rocks is intensified and hence
along which groundwater movement is concentrated.
OFFICIAL PLAN
A comprehensive plan for the provision of adequate sewage
systems adopted by the Council of Lower Saucon Township and submitted
to and approved by the Department as provided by the Act and Chapter
71 of the Department's regulations.
PINNACLES
Tall, slender spires of carbonate bedrock. Pinnacles are
formed from the chemical dissolution of carbonate rocks along planes
of weakness (joints and fractures).
SINKHOLES
Funnel-shaped or steep-sided depressions in the land surface
that are caused by the dissolution and collapse or subsidence of the
roofs of subterranean caverns in carbonate geologic formations. In
size, they can vary from a few feet to more than 100 feet in width.
