As used in this chapter, the following terms shall have the
meanings indicated:
The work of producing crops including tillage, land clearing,
plowing, disking, harrowing, planting, harvesting crops, or pasturing
and raising of livestock and installation of conservation measures.
Construction of new buildings or impervious area is not considered
an agricultural activity.
A landowner, developer or other person who has filed an application
to the municipality for approval to engage in any regulated activity
at a project site in the municipality.
Activities, facilities, designs, measures or procedures used
to manage stormwater impacts from regulated activities, to meet state
water quality requirements, to promote groundwater recharge and to
otherwise meet the purposes of this chapter. Stormwater BMPs may be
structural or nonstructural. Nonstructural BMPs or measures refer
to operational and/or behavior-related practices that attempt to minimize
the contact of pollutants with stormwater runoff. Structural BMPs
or measures consist of a physical device or practice that is installed
to capture and treat stormwater runoff. Structural BMPs comprise a
wide variety of practices and devices, from large-scale retention
ponds and constructed wetlands, to small-scale underground treatment
systems, infiltration facilities, filter strips, low-impact design,
bioretention, wet ponds, permeable paving, grassed swales, riparian
or forested buffers, rain gardens, sand filters, detention basins,
and manufactured devices. Structural stormwater BMPs are permanent
appurtenances to the project site.
An area of permanent native vegetation, including trees,
shrubs, and herbaceous vegetation, that exists or is established to
protect streams.
A conservation district, as defined in Section 3(c) of the
Conservation District Law [3 P.S. § 851(c)], which has the
authority to administer and enforce all or a portion of the erosion
and sediment control program in this commonwealth.
The volume of runoff that is captured and released into the
waters of this commonwealth at a controlled rate.
The Pennsylvania Department of Environmental Protection.
See "project site."
An impervious or impermeable surface which is disconnected
from any stormwater drainage or conveyance system and is redirected
or directed to a pervious area which allows for infiltration, filtration,
and increased time of concentration.
An unstabilized land area where an earth disturbance is occurring
or has occurred.
Construction or other human activity which disturbs the surface
of the land, including, but not limited to, clearing and grubbing;
grading; excavations; embankments; road maintenance; building construction;
the moving, depositing, stockpiling of soil, rock or earth materials.
The natural process by which the surface of the land is worn
away by water, wind or chemical action.
The dominant land cover during the five-year period immediately
preceding a proposed regulated activity, including mature canopy trees
and other vegetation.
Federal Emergency Management Agency.
Any land area susceptible to inundation by water from any
natural source or delineated by applicable FEMA maps and studies as
being a special flood hazard area. Included are lands adjoining a
river or stream that have been or may be expected to be inundated
by a one-hundred-year flood and areas that comprise Group 13 Soils,
as listed in the DEP Technical Manual for Sewage Enforcement Officers.
The channel of the watercourse and those portions of the
adjoining floodplains that are reasonably required to carry and discharge
the one-hundred-year flood. Unless otherwise specified, the boundary
of the floodway is as indicated on maps and flood insurance studies
provided by FEMA. In an area where no FEMA maps or studies have defined
the boundary of the one-hundred-year floodway, it is assumed, absent
evidence to the contrary, that the floodway extends from the stream
to 50 feet from the top of the bank of the stream.
Planning and activities necessary for the management of forestland.
These include conducting a timber inventory, preparation of forest
management plans, silvicultural treatment, cutting budgets, logging
road design and construction, timber harvesting, site preparation
and reforestation.
A surface that prevents the infiltration of water into the
ground. Impervious surfaces (or areas) shall include, but not be limited
to, roofs of all structures, sidewalks, paved parking areas and driveways.
Decks, parking areas, and driveway areas are not counted as impervious
areas if they do not prevent infiltration.
Inclusive of any or all of the following meanings:
The division of a parcel of land into two or more parcels;
The construction, reconstruction, conversion, structural alteration,
relocation, or enlargement of any buildings, structures, or accessory
structures;
Any use or change in use of buildings or land;
Any extension of the use of land;
Any clearing, grading, or other movement of land;
Mining, dredging, filling, grading, paving, excavation or drilling
operations; or
The storage, deposition or extraction of materials, public or
private sewage disposal systems or water supply facilities; for which
permission may be required pursuant to a municipal land development
ordinance.
Borough of Muncy, Lycoming County, Pennsylvania, or its representative.
USDA Natural Resources Conservation Service (previously SCS).
The maximum rate of stormwater runoff from a specific storm
event.
Any area not defined as impervious.
The specific area of land where any regulated activities
in the municipality are planned, conducted, or maintained.
Any person licensed by the Pennsylvania Department of State
or otherwise qualified by law to perform the work required by this
chapter.
Any earth disturbances or any activities that involve the
alteration or development of land in a manner that may affect stormwater
runoff.
Any part of precipitation that flows over the land.
Soils or other materials transported by surface water as
a product of erosion.
The regulatory requirements to protect, maintain, reclaim,
and restore water quality under Pennsylvania Code Title 25 and the
Clean Streams Law.[3]
Drainage runoff from the surface of the land resulting from
precipitation or snow or ice melt.
The Stormwater Management Plan for managing stormwater runoff
adopted by the County of Lycoming as required by the Act of October
4, 1978, P.L. 864 (Act 167), as amended, and known as the "Storm Water
Management Act."[4]
The plan prepared by the developer or his representative
indicating how stormwater runoff will be managed at the development
site in accordance with this chapter. "Stormwater management site
plan" will be designated as "SWM site plan" throughout this chapter.
For purposes of administration of this chapter, a stream
is defined as a perennial and intermittent watercourses identified
through site inspection and U.S. Geological Survey (USGS) maps. Perennial
streams are those which are depicted on a USGS map with a solid blue
line. Intermittent streams are those which are depicted on a USGS
map with a dotted blue line.
Rivers, streams, creeks, rivulets, impoundments, ditches,
watercourses, storm sewers, lakes, dammed water, wetlands, ponds,
springs and other bodies or channels of conveyance of surface and
underground water, or parts thereof, whether natural or artificial,

Region or area drained by a river, watercourse or other surface
water of the commonwealth.
