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 Township.
Activities, 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.
The Montgomery 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 Township.
See "earth disturbance activity." The term includes redevelopment.
The specific tract of land where any earth disturbance activities
in the Township 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.
National Pollutant Discharge Elimination System, the 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 Township'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 § 92a.2.[1]
The specific area of land where any regulated earth disturbance
activities in the Township are planned, conducted or maintained.
Earth disturbance activities on land which has previously
been disturbed or developed.
Earth disturbance activity of one acre or more with a point
source discharge to surface waters or the Township's storm sewer system
or five acres or more regardless of the planned runoff. This includes
earth disturbance on any portion of, part of, or during any stage
of, a larger common plan of development. This only includes road maintenance
activities involving 25 acres or more of 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.
A 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 of 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.
