Notes
Metropolitan Water District of Southern California (1927)
Established to create Colorado River Aquaduct (1933-1941).
Author of “Silent Spring” (1962)

Restrictions on the discharge of pollutants into the environment.
________ guidelines reduce discharge of pollutants with serious environmental impacts.
EPA has ________ guidelines for more than 50 categories.
Effluent Standards
Pollution type that is discharged directly from a specific site. Ex. sewage treatment plant or industrial pipe.
Point Source Pollution
Contaminated runoff from many sources.
Non-Point Source Pollution
Water that is safe to drink.
Potable Water.
One or more rock/sediment strata that is saturated and permeable to yield eocnomically significant quantities of water to wells or springs.
Includes geologic material that is currently used or oculd be used as source of water within the target distance limit.
Wells can be drilled into these and water can be pumped out.
Recharged via precipitation and porous rock.
Rates of recharge vary - consider this when pumping.
Aquifer
Area where freshwater meets saltwater.
Estuary
Shallow body of water located alongside a coast.
Lagoon
Freshwater/brackish/saltwater wetland found along water bodies.
Does not accumulate appreciable peat deposits and is dominated by herbaceous vegetation.
Marsh
Pond, lake, tank, or basin that stores/controls water.
Natural or man-made.
Resevoir
Rivers, lakes, oceans, and coastal tidewaters
Surface Water
Freshwater wetland that has spongy, muddy land, and a lot of water.
Swamp
Region drained by, or contributing water to, surface water.
Watershed.
Underground boudnary between soil surface and the area where groundwater saturates spaces between sediments and cracks in rock.
Water pressure and atmospheric pressure are equal at this boundary.
Water Table
Swamps, marshes, and bogs.
Inundated or saturated by surface or groundwater at a frequency and duration sufficient to support vegetation adapted for life in saturated soil conditions.
Natural or constructed.
Wetlands
This act requires anyone wanting to discharge pollutants into a body of water to obtain a permit.
Regulates amount of water that can be discharged and types of pollutants that can be released.
Clean Water Act of 1972 (amended 1977)
Official name: Federal Water Pollution Control Act.
Permit required to discharge pollutants into the water.
Must be obtained from National Pollutant Discharge Elimination System (NPDES).
Point Source Discharge Permit
Federal act that cut off Federal funding for metropolitan areas not in air quality attainment.
In non-attainment areas, new pollution sources are allowed only if there is a reduction in pollutants greater thant he pollutants contributed by the new source.
EPA publishes a “Green Book” which lists National Ambient Air Quality Standards, designations, classfications, and non-attainment status.
Clean Air Act of 1970 (amended 1977 and 1990).
Clean Air Act notes
Federal Government sets ambient standards and states must devise methods that enable these standards to be met.
Air Quality Control Regions created to measure air quality in air sheds (can’t measure air quality in only one area).
Requires a permit to release pollutants in the air.
Monitors: ozone, particulate matter, Carbon Monoxide, Nitrogen Dioxide, Sulfur Dioxide, and Lead.
Process that relates to air quality and requires a project will not increase emissions above a specified _______ increment.
Prevention of Significant Deterrioration (PSD)
These standards set the maximum air contaminant concentrations allowed in the ________ air.
Ambient Air Quality Standards
Legislation that resulted in creation of Council on Environmental Quality.
Requires Federal agencies to prepare an Environmental Impact Statement (EIS) for all major Federal actions that could affect quality of the human environment.
Not all Federal actions require a full EIS.
Agencies first prepare a smaller, shorter Environmental Assessment (EA). EA findings determine whether EIS is required.
If EA shows no likely impact, agency can release a finding of No Significant Impact (FONSI) and carry on. If not, full EIS required.
More FONSI than full EIS.
National Environmental Policy Act of 1969 (NEPA)
