The Stormwater Pollution Prevention Plan, often abbreviated as SWPPP or SW3P, is a plan created by constructors to show their plans for sediment and erosion control. [1] Typically these plans are part of an overall design that details procedures to be followed during various phases of construction.
Stormwater, also written storm water, is water that originates from precipitation , including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil ( infiltrate ) and become groundwater , be stored on depressed land surface in ponds and puddles , evaporate back into the atmosphere, or contribute to surface runoff .
Beginning in the 20th century, designers of industrial and municipal sewage pollution controls typically utilized engineered systems (e.g. filters, clarifiers, biological reactors) to provide the central components of pollution control systems, and used the term "BMPs" to describe the supporting functions for these systems, such as operator training and equipment maintenance.
Pollution prevention (P2) is a strategy for reducing the amount of waste created and released into the environment, particularly by industrial facilities, agriculture, or consumers. Many large corporations view P2 as a method of improving the efficiency and profitability of production processes through waste reduction and technology ...
Pollution prevention practices include low impact development (LID) or green infrastructure techniques - known as Sustainable Drainage Systems (SuDS) in the UK, and Water-Sensitive Urban Design (WSUD) in Australia and the Middle East - such as the installation of green roofs and improved chemical handling (e.g. management of motor fuels & oil ...
Stormwater permits typically require facilities to prepare a Stormwater Pollution Prevention Plan and implement best management practices, but do not specify numeric effluent limits and may not include regular monitoring requirements. Some permits cover both stormwater and non-stormwater discharges.
Silt fence installed up-slope of a vegetated stream buffer. A silt fence, sometimes (misleadingly) called a filter fence, [1] is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment (loose soil) in stormwater runoff.
To address the nationwide problem of stormwater pollution, Congress broadened the CWA definition of "point source" in 1987 to include industrial stormwater discharges and municipal separate storm sewer systems ("MS4"). [30] These facilities are required to obtain NPDES permits. This 1987 expansion was promulgated in two phases.
