Environmental Protection Agency (EPA)

An independent federal government agency established in 1970 and charged with coordinating effective governmental action concerning the environment, including setting standards, promulgating and enforcing regulations, and initiating and implementing environmental programs. Two areas of jurisdiction that most directly affect agricultural production are the registration of pesticides and implementation of the Clean Water Act.

Environmental Quality Incentives Program (EQIP)

A program created by the FAIR Act of 1996 to provide primarily cost-sharing assistance, but also technical and educational assistance, aimed at reducing soil, water, and related natural resource problems. The program replaces the Agricultural Conservation Program, the Water Quality Incentives Program, the Great Plains Conservation Program, and the Colorado River Basin Salinity Control Program. EQIP is authorized at $1.3 billion in mandatory spending over 7 years (total), with at least half of the funding targeted to environmental concerns associated with livestock production; spending in general is to be targeted to state-designated priority areas. EQIP is to be operated to maximize the environmental benefits per dollar expended.

Epicenter

Point on the Earth's surface directly above the focus of an earthquake.

Epilimnion

See thermal stratification

Equilibrium

The amount of output supplied equals the amount demanded. At equilibrium, the market has neither a tendency to rise nor fall but clears at the existing price.

Equilibrium Price

The price at which the quantity supplied and the quantity demanded are equal to each other.

Equivalent Variation

The amount of money one would accept to forgo a benefit such as a price decrease or the amount of income one would pay to avoid a harm such as a price increase. Money required to leave an individual as well off as after the economic change. Amount an individual would be willing to accept to forgo the change, or willing to pay to avert the change.

Erosion

The wearing away of the land surface. Unconsolidated materials, such as soil, erode more rapidly than consolidated materials, such as rock. The most common causes of erosion are wind and moving water. The susceptibility of soil to erosion is quantified by the erosion index. Water causes sheet, rill, and gully erosion.

Erosion (erodibility) index (EI)

The erosion (sometimes called erodibility) index is created by dividing potential erosion (from all sources except gully erosion) by the T value, which is the rate of soil erosion above which long term productivity may be adversely affected. The erodibility index is used in the conservation compliance and Conservation Reserve Programs. For example, one of the eligibility requirements for the CRP is that land have an EI greater than 8.

Ethanol

C2H5OH; the alcohol product of carbohydrate fermentation used in alcoholic beverages and for industrial purposes (also known as ethyl alcohol or grain alcohol). It is blended with gasoline to make gasohol. In the 1998/99 corn marketing year, about 540 million bushels (5.5%% of the corn crop and 7.2% of domestic use) will be used to produce about 1.5 billion gallons of ethanol.
