As used in this chapter, the following terms shall have the meanings
indicated:
AGRICULTURAL ACTIVITY
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.
APPLICANT
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.
BEST MANAGEMENT PRACTICE (BMP)
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 are commonly
grouped into one of two broad categories or measures: "structural"
or "nonstructural." In this chapter, nonstructural BMPs or measures
refer to operational and/or behavior-related practices that attempt
to minimize the contact of pollutants with stormwater runoff, whereas
structural BMPs or measures are those that consist of a physical device
or practice that is installed to capture and treat stormwater runoff.
Structural BMPs include, but are not limited to, 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.
CONSERVATION DISTRICT
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.
DEP
The Pennsylvania Department of Environmental Protection.
DETENTION
The volume of runoff that is captured and released into the
waters of this commonwealth at a controlled rate.
DISCONNECTED IMPERVIOUS AREA (DIA)
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.
DISTURBED AREA
An unstabilized land area where an earth disturbance is occurring
or has occurred.
EARTH DISTURBANCE
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;
and the moving, depositing, or stockpiling of soil, rock or earth
materials.
EROSION
The natural process by which the surface of the land is worn
away by water, wind or chemical action.
EXISTING CONDITION
The dominant land cover during the five-year period immediately
preceding a proposed regulated activity, including mature canopy trees
and other vegetation.
FEMA
Federal Emergency Management Agency
FLOODPLAIN
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 100-year flood and areas that comprise Group 13 Soils, as listed
in the DEP Technical Manual for Sewage Enforcement Officers.
FLOODWAY
The channel of the watercourse and those portions of the
adjoining floodplains that are reasonably required to carry and discharge
the 100-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 100-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.
FOREST MANAGEMENT/TIMBER OPERATIONS
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.
IMPERVIOUS SURFACE (IMPERVIOUS AREA)
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.
LAND DEVELOPMENT (DEVELOPMENT)
Inclusive of any or all of the following meanings:
A.
The division of a parcel of land into two or more parcels;
B.
The construction, reconstruction, conversion, structural alteration,
relocation, or enlargement of any buildings, structures, or accessory
structures;
C.
Any use or change in use of buildings or land;
D.
Any extension of the use of land;
E.
Any clearing, grading, or other movement of land;
F.
Mining, dredging, filling, grading, paving, excavation or drilling
operations; or
G.
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.
MUNICIPALITY
Borough of Hughesville, Lycoming County, Pennsylvania, or
its representative.
NRCS
USDA Natural Resources Conservation Service (previously SCS).
PEAK DISCHARGE
The maximum rate of stormwater runoff from a specific storm
event.
PROJECT SITE
The specific area of land where any regulated activities
in the municipality are planned, conducted, or maintained.
QUALIFIED PROFESSIONAL
Any person licensed by the Pennsylvania Department of State
or otherwise qualified by law to perform the work required by this
chapter.
REGULATED ACTIVITIES
Any earth disturbances or any activities that involve the
alteration or development of land in a manner that may affect stormwater
runoff.
RUNOFF
Any part of precipitation that flows over the land.
SEDIMENT
Soils or other materials transported by surface water as
a product of erosion.
STATE WATER QUALITY REQUIREMENTS
The regulatory requirements to protect, maintain, reclaim,
and restore water quality under Pennsylvania Code Title 25 and the
Clean Streams Law.
STORMWATER
Drainage runoff from the surface of the land resulting from
precipitation or snow or ice melt.
STORMWATER MANAGEMENT PLAN
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."
STORMWATER MANAGEMENT SITE PLAN
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.
STREAM
For purposes of administration of this chapter, a stream
is defined as a perennial and intermittent watercourse 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.
WATERS OF THE COMMONWEALTH
Rivers, streams, creeks, rivulets, impoundments, ditches,
watercourses, storm sewers, lakes, dammed water, wetlands, ponds,
