As used in this chapter, the following terms shall have the
meanings indicated:

action of man's activities and natural processes at a rate greater
than would occur because of the natural processes alone.
ACT 167
Act of October 4, 1978, P.L. 864, (Act 167), as amended,
and known as the "Storm Water Management Act."
AGRICULTURAL ACTIVITY
Activities associated with agriculture such as agricultural
cultivation, agricultural operation, and animal heavy use areas. This
includes 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

application to the Borough for approval to engage in any regulated
activity at a project site in the Borough.
AUTHORIZED ENFORCEMENT AGENCY

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, sand filters, detention basins, and manufactured
devices. Structural stormwater BMPs are permanent appurtenances to
the project site.

chemical or infectious characteristics may cause, or significantly
contribute to, a substantial present or potential hazard to human
health, safety, property, or the environment when improperly treated,
stored, transported, disposed of, or otherwise managed.
HYDROLOGIC SOIL GROUP (HSG)
Infiltration rates of soils vary widely and are affected
by subsurface permeability as well as surface intake rates. Soils
are classified into four HSGs (A, B, C, and D) according to their
minimum infiltration rate, which is obtained for bare soil after prolonged
wetting. The NRCS defines the four groups and provides a list of most
of the soils in the United States and their group classification.
The soils in the area of the development site may be identified from
a soil survey report that can be obtained from local NRCS offices
or conservation district offices. Soils become less pervious as the
HSG varies from A to D.

and any connections to the storm drain system and/or waters of the
commonwealth from indoor drains and sinks, regardless of whether said
drain or connections had been previously allowed, permitted, or approved
by an authorized enforcement agency; or

to, roofs, additional indoor living spaces, patios, garages, storage
sheds and similar structures, and any new streets and sidewalks. However,

not be considered impervious if such surface or area does not diminish
the capacity for infiltration of stormwater for storms up to, and
including, a two-year, twenty-four-hour storm event.

store runoff close to its source. Rather than rely on costly large-scale
conveyance and treatment systems, LID addresses stormwater through
a variety of small, cost-effective landscape features located on-site.
