the meanings indicated:
The removal of the surface of the land through the combined
action of human activity and natural processes at a rate greater than
would occur because of the natural process alone.
Activities associated with agriculture such as agricultural
cultivation, agricultural operation, and animal heavy use areas. This
includes the work of producing crops, tillage, land clearing, plowing,
disking, harrowing, planting, harvesting crops, or pasturing and raising

of new buildings or impervious area is not considered an agricultural
activity.
As applied to land, a change in topography as a result of
the moving of soil and rock from one location or position to another;
changing of surface conditions by causing the surface to be more or

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:
"nonstructural" or "structural." "Nonstructural" BMPs are measures
referred to as operational- and/or behavior-related practices that
attempt to minimize the contact of pollutants with stormwater runoff
whereas "structural" BMPs are measures 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 wet 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.

Infiltration rates of soils vary widely and are affected
by subsurface permeability as well as surface intake rates. Soils
are classified into one of four HSG (A, B, C, and D) according to
their minimum infiltration rate, which is obtained for bare soil after
prolonged wetting. The Natural Resource Conservation Service (NRCS)
defines the four groups and provides a list of most of the soils in

area of interest may be identified from a soil survey report from
the local NRCS office or the Dauphin County Conservation District.
