Natural Resources Planning Flashcards
Earth Day
The first Earth Day was April 22, 1970.
Metropolitan Water District of Southern California
was established in 1927 to create the Colorado River Aqueduct. The Colorado River Aqueduct, a water pipeline to Los Angeles, was built between 1933 and 1941 and is owned and operated by the Metropolitan Water District of Southern California.
Rachel Carson
Author of Silent Spring, which was published in 1962. In the book, Carson examined the dangers of chemical pesticides, such as DDT, on plants, animals, and humans. The book greatly influenced the way people think about the environment.
Effluent Standards
set restrictions on the discharge of pollutants into the environment. Effluent guidelines reduce the discharge of pollutants that have serious environmental impacts. The EPA has effluent guidelines for more than 50 categories.
Point Source Pollution
is discharged directly from a specific site, such as a sewage treatment plant or an industrial pipe.
Non-Point Source Pollution
contaminated runoff from many sources
Potable water
water that is safe to drink
Aquifer
one or more strata of rock or sediment that is saturated and sufficiently permeable to yield economically significant quantities of water to wells or springs. an aquifer includes any geologic material that is currently used or could be used as a source of water within the target distance limit. Wells can be drilled into aquifers and water can be pumped out. Precipitation eventually adds water (recharge) into the porous rock of the aquifer. The rate of recharge is not the same for all aquifers, through, and that must be considered when pumping water from a well.
Estuary
an area where freshwater meets saltwater
Lagoon
a shallow body of water located alongside a coast
Marsh
a type of freshwater, brackish water or saltwater wetland found along rivers, ponds, lakes, and coasts. It does not accumulate appreciable peat deposits and is dominated by herbaceous vegetation.
Reservoir
a pond, lake, tank, or basin that can be used for the storage and control of water, and can be either natural or man-made
Surface Water
includes rivers, lakes, oceans, ocean-like water bodies, and coastal tidal waters
Swamp
a freshwater wetland that has spongy, muddy land and a lot of water
Watershed
a region drained by, or contributing water to, surface water
Water table
the underground boundary between the 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.
Wetlands
Include swamps, marshes, bogs, and other similar areas. Wetlands are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support vegetation typically adapted for life in saturated soil conditions. Wetlands can be natural or constructed.
Clean Water Act
passed in 1972, with a major amendment in 1977. The office name was the Federal Water Pollution Control Act but Clean Water Act became the act’s common name. The act requires anyone wanting to discharge pollutants into a body of water to obtain a permit. It also regulates the amount of water than can be discharged and the types of pollutants that can be released
Point Source Discharge Permit
To discharge pollutants into the water, a Point Source Discharge Permit must be obtained from the National Pollutant Discharge Elimination System (NPDES).
Clean Air Act
Congress established much of the basic structure of the Clean Air Act in 1970 and made major revisions in 1977 and 1990. The act includes provisions that cut off federal funding for metropolitan areas not in attainment. In non-containment areas, new pollution sources are allowed only if there is a reduction in pollutants greater than the pollutants contributed by the source.
The clean air act monitors six pollutants: Ozone, particulate matter, carbon monoxide, nitrogen dioxide, sulfur dioxide, lead.
Prevention of Significant Deterioration (PSD)
relates to air quality and requires that a project will not increase emissions above a specified PSD increment.
Ambient Air Quality Standards
set the maximum air containment concentrations allowed in the ambient air. According to the EPA, national emissions of the six most common air pollutants have been reduced substantially since 1970.
The National Environmental Policy Act of 1969 (NEPA)
resulted in the creation of the Council on Environmental Quality. NEPA requires federal agencies to prepare an Environmental Imapct Statement (EIS) for all major federal actions that could significantly affect the quality of the human environment. Not all federal actions require a full EIS. Agencies can first pepare a smalelr, shorter document called and Environmental Assessment (EA). The finding of the EA determins whether an EIS is required. If the EA indicates that no significant impcat is likely, then the agency can release a finding of no signifcant impact (FONSI) and carry on with the proposed action. Otherwise the agency must then conduct a full-scale EIS. Most EAs result in a FONSI.
The Rivers and Harbors Act of 1899
(Considered the oldest environmental law in the US) prohibited the construction of any bridge, dam, dike, or causeway over any navigable waterway in the country without Congressional approval. The act also required Congressional approval for all wharves, piers, jetties, and the excavation or infill of navigable waters.
