Terms defined. As used in this article, the following terms shall
have the meanings indicated:
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 article. Stormwater BMPs are commonly
grouped into one of two broad categories or measures: "structural"
or "nonstructural." In this article, 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.
CONSERVATION DISTRICT
A conservation district, as defined in Section 3(c) of the
Conservation District Law [3 P.S. § 851(c)] that has the
authority under a delegation agreement executed with DEP to administer
and enforce all or a portion of the regulations promulgated under
25 Pa. Code Ch. 102.

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. Earth disturbance activity is subject to regulation
under 25 Pa. Code Ch. 92a, 25 Pa. Code Ch. 102, or the Clean Streams
Law.

small MS4.
STATE WATER QUALITY REQUIREMENTS
The regulatory requirements to protect, maintain, reclaim
and restore water quality under Title 25 of the Pennsylvania Code
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 managing stormwater runoff
adopted by Allegheny County 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 article. "Stormwater management site
plan" will be designated as "SWM site plan" throughout this article.
