The permits (excluding most stormwater management permits) also specify procedures for collection of wastewater samples and the test methods that will be used to analyze the samples. [18]: 3–2 [18]: 8–11 Types of permits. Individual – A unique permit is issued for each discharger.
Stormwater management, as a specialized area within the field of environmental engineering, emerged later in the 20th century, and some practitioners have used the term BMP to describe both structural or engineered control devices and systems (e.g. retention ponds) to treat polluted stormwater, as well as operational or procedural practices (e ...
The other states have developed their own state-specific industrial stormwater permits (e.g. California's Industrial General Permit). [8] State-issued general permits often include the same requirements as EPA's permit, but some states have additional requirements. [6] A silt fence is a type of sediment control used on construction sites.
Some permits cover both stormwater and non-stormwater discharges. NPDES permits must be reissued every five years. Permit agencies (EPA, states, tribes) must provide notice to the public of pending permits and provide an opportunity for public comment. [67] In 2012, EPA estimated that there are over 500,000 stormwater permittees.
For permits other than stormwater permits, the agencies issue effluent limitations for specific pollutants, pursuant to the Clean Water Act (CWA). The basis for these limitations depends on the type of discharging facility, the discharge characteristics and status of the specific surface water body receiving the discharge.
To implement TMDLs with point sources, wasteload allocations are incorporated into discharge permits for these sources. [13] The permits are issued by EPA or delegated state agencies under the National Pollutant Discharge Elimination System . Nonpoint source discharges (e.g. agriculture) are generally in a voluntary compliance scenario.
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 .
