	SWRCB TMDL Background
		A TMDL requires that all sources of pollution and all aspects of a watershed's drainage system be reviewed, not just the pollution coming from discrete conveyances (known as point sources), such as a discharge pipe from a factory or a sewage treatment plant.
		In the 1970's, point source pollution was considered the most significant problem affecting water quality in rivers and streams.
		Nonpoint sources are not defined in statute, but are considered everything that is not covered under the point source definition.

	question2a
		It is considered to be point source pollution because it is entering a body of water at an identifiable, single-point location, and it is definitely carrying pollutants.
		This pollution can be measured, also meaning it is point source pollution.
		This pollution is coming directly from a pipe.

	GREEN / Marie Harrison And The Fight For Bayview-Hunters Point
		The official -- though disputed -- reason for the plant's continued operation is to ensure that the City's power demands never go unmet, which implies that using electricity more efficiently may be one way to alleviate the need for the largest single point source of pollution in the City.
		These are some of the largest stationary sources of air pollution in the City, "and they're all in walking distance from one another -- and I mean a leisurely walk," says Harrison.
		She points out that the plant was originally scheduled to be shut down in 2001, and, for its neighbors, six more years of operation has meant six more years of poison and suffering.

		Discharges from point sources of pollution often are continuous, and easier to identify and measure compared to NPS discharges.
		Discharges from nonpoint sources are usually intermittent, associated with a rainfall or snowmelt event, and occur less frequently and for shorter periods of time than do point source discharges.
		Point source pollutants are usually municipal or industrial wastes, but are not limited to these.

	Smart Communities Network: Water Efficiency Pollution Prevention
		The sources of water pollution are classified as "point sources" and "nonpoint sources." Point sources discharge pollutants into surface waters or into groundwater through a detectable "point, " such as pipes from industrial facilities, treatment plants, and combined sewers.
		Although point sources still contribute some to water pollution, control measures have greatly reduced their impact.
		Nonpoint sources include atmospheric deposition, contaminated sediments, and land practices that generate polluted runoff such as agriculture, logging, onsite sewage disposal, and municipal stormwater management.
