Glossary
BEST MANAGEMENT PRACTICES “encompass the schedules of activities, prohibitions of practices,
maintenance procedures, and other management practices or prevent or reduce the pollution of waters of the
State.” 10
Nonstructural BMP’s can be utilized for delivery reduction as well as source control purposes (e.g.,
stormwater control plans, street sweeping, and buffer zones.
Structural BMP’s temporarily store and treat stormwater runoff, and are not intended to reduce nonpoint
source pollution at the source (e.g., detention basins, grassed swales and filter strips).
BIOENGINEERING combines basic engineering principles with biological and ecological concepts.
SPECIFIC CONDUCTANCE “...a measure of the ability of a water to conduct an electrical current. It is
related to the type and concentration of ions in solution and can be used for approximating the dissolvedsolids
content of the water.” 11
SURFACE WATER QUALITY CLASSIFICATIONS:
FW1 fresh waters that originate in and are wholly within Federal or State parks, forests, fish and wildlife
lands and other special holdings, that are to be maintained in their natural state of quality and not subjected
to any man-made wastewater discharges.
FW2 fresh waters that are not designated as FW1.
Nontrout waters fresh waters that are neither trout production or trout maintenance.
TM (trout maintenance) waters designated for the support of trout throughout the year.
TP (trout production) waters designated for use by trout for spawning or nursery purposes during their first
summer.
WETLANDS CLASSIFICATIONS
Exceptional wetlands either discharge into FW-1 waters or FW-2 Trout Production waters, or which serve
as habitats for threatened or endangered species. This designation stipulates a 150' transitional area (buffer)
when such a wetland is subject to disturbance.
Intermediate wetlands are those not defined as exceptional or ordinary. A 50' transition area is required
adjacent to these wetlands.
Ordinary wetlands do not have the environmental qualities that exceptional wetlands do. In addition they
tend to be isolated and significantly surrounded by development. Likely examples include drainage ditches,
swales and detention facilities.
