The words "shall" and "must" are mandatory; the words "may" and "should"
are permissive.
The removal of the surface of the land through the combined
action of human activities and the natural processes, at a rate greater
than would occur because of the natural process alone.
A landowner, developer or other person who has filed an application
for approval to engage in any regulated earth disturbance activity
at a project site in the municipality.
Activities, facilities, designs, measures or procedures used to manage stormwater impacts from regulated earth disturbance activities, to meet state water quality requirements, to promote groundwater recharge and to otherwise meet the purposes of this Chapter 23C.
The Lehigh County Conservation District.
The Pennsylvania Department of Environmental Protection.
A person that seeks to undertake any regulated earth disturbance
activities at a project site in the municipality.
See "earth disturbance activity." The term includes redevelopment.
The specific tract of land where any earth disturbance activities
in the municipality are planned, conducted or maintained.
A 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, stockpiling, or storing of soil, rock
or earth materials.
The process by which the surface of the land, including channels,
is worn away by water, wind, or chemical action.
A plan for a project site which identifies BMPs to minimize
accelerated erosion and sedimentation.
Replenishment of existing natural underground water supplies.
A surface that prevents the infiltration of water into the
ground. Impervious surface includes, but is not limited to, any roof,
parking or driveway areas, and any new streets and sidewalks. Any
surface areas designed to initially be gravel or crushed stone shall
be assumed to be impervious surfaces.
Lower Macungie Township, Lehigh County, Pennsylvania.
National Pollutant Discharge Elimination System, federal
government's system for issuance of permits under the Clean Water
Act, which is delegated to DEP in Pennsylvania.
"Point source" as described in 40 CFR 122.2 at the point
where the municipality's storm sewer system discharges to surface
waters of the commonwealth.
An individual, partnership, public or private association
or corporation, or a governmental unit, public utility or any other
legal entity whatsoever which is recognized by law as the subject
of rights and duties.
Any discernible, confined and discrete conveyance, including,
but not limited to, any pipe, ditch, channel, tunnel, or conduit from
which stormwater is or may be discharged, as defined in state regulations
at 25 Pa.Code § 92.1.
The specific area of land where any regulated earth disturbance
activities in the municipality are planned, conducted or maintained.
Earth disturbance activities on land which has previously
been disturbed or developed.
Earth disturbance activity one acre or more with a point
source discharge to surface waters or the municipality's storm
sewer system, or five acres or more regardless of the planned runoff.
This includes earth disturbance on any portion of, part, or during
any stage of, a larger common plan of development. This only includes
road maintenance activities involving 25 acres or more or earth disturbance.
Earth disturbance activities within the existing road cross-section,
such as grading, and repairing existing unpaved road surfaces, cutting
road banks, cleaning or clearing drainage ditches and other similar
activities.
Conveyance or system of conveyances (including roads with
drainage systems, municipal streets, catch basins, curbs, gutters,
ditches, man-made channels or storm drains) primarily used for collecting
and conveying stormwater runoff.
As defined under state regulations–protection of designated
and existing uses (see 25 Pa.Code, Chapters 93 and 96)–including:
Each stream segment in Pennsylvania has a "designated use,"
such as "cold water fishery" or "potable water supply," which are
listed in Chapter 93. These uses must be protected and maintained,
under state regulations.
"Existing uses" are those attained as of November 1975, regardless
whether they have been designated in Chapter 93, regulated earth disturbance
activities must be designed to protect and maintain existing uses
and maintain the level of water quality necessary to protect those
uses in all streams, and to protect and maintain water quality in
special protection streams.
Water quality involves the chemical, biological and physical
characteristics of surface water bodies. After regulated earth disturbance
activities are complete, these characteristics can be impacted by
addition of pollutants such as sediment, and changes in habitat through
increased flow volumes and/or rates as a result of changes in land
surface area from those activities. Therefore, permanent discharges
to surface waters must be managed to protect the stream bank, streambed
and structural integrity of the waterway, to prevent these impacts.
The surface runoff generated by precipitation reaching the
ground surface.
Any and all rivers, streams; creeks, rivulets, impoundments,
ditches, watercourses, storm sewers, lakes, dammed water, wetlands,
ponds, springs, and all other bodies or channels of conveyance of
surface water, or parts thereof, whether natural or artificial, within
or on the boundaries of this commonwealth.
A channel or conveyance of surface water, such as a stream
or creek, having defined bed and banks, whether natural or artificial,
with perennial or intermittent flow.
Region or area drained by a river, watercourse or other body
of water, whether natural or artificial.
