H-2A program

A program that permits employers to apply for nonimmigrant alien workers to perform work of a seasonal or temporary nature. The program is authorized by the Immigration and Nationality Act, as amended by the Immigration Reform and Control Act of 1986. The purpose of the H-2A program is to assure employers an adequate labor force, on the one hand, and to protect the jobs and wages of U.S. workers, on the other.

HACCP-based Inspection Models Project (HIMP)

A new inspection model, developed by the Food Safety and Inspection Service, for processingplants that slaughter young, healthy, and uniform animals. The project is a natural extension of Hazard Analysis and Critical Control Point System (HACCP) in all meat and poultry plants. Under the project, the FSIS established performance standards for food safety and nonfood safety conditions. Plants must extend their HACCP systems to address the food safety conditions, and develop process control plans to address nonfood safety conditions. Plants are responsible for identifying and removing carcasses that do not meet these standards. Under HIMP, as under regular HACCP, a federal inspector still inspects all carcasses and makes the determination as to whether a carcass is adulterated. Also, a verification inspector takes plant records and samples of products for examination, focusing on the HACCP and process control plans and whether the plant is meeting relevant carcass performance standards.
See Also:
adulterated. Food Safety and Inspection Service. HACCP. inspection. meat. poultry. process. processing.

Habitat Conservation Plan (HCP)

Ensures there is adequate minimizing and mitigating of the effects of an authorized incidental take. Incidental take permits are required when nonfederal activities will result in an incidental take of threatened species or endangered species. The purpose of the incidental take permit is to authorize the incidental take of a listed species, not to authorize the activities that result in take.

Hard White Wheat Incentive Payments (HWWIP)

As authorized by the Farm Security and Rural Investment Act of 2002 (Sec. 1616), a new three-year, $20 million Farm Service Agency program designed to increase the number of bushels of hard white wheat produced in the U.S. for the 2003 through 2005 crop years. The program offers a production incentive in the amount of 20 cents per bushel at a maximum of 60 bushels for each planted acre. An additional incentive in the amount of two dollars per acre is provided for each acre planted to certified seed. Producers are eligible to earn both the production incentive and the certified seed incentive in the same year. The total Commodity Credit Corporation outlay for the three years is to be based on not more than two million acres or the equivalent volume of production. Both hard white winter wheat and hard white spring wheat are eligible for payment.

Harvard Risk Assessment

In April 1998, the USDA commissioned the Harvard Center for Risk Analysis to conduct an analysis and evaluation of the current measures implemented by the federal government to prevent the spread of BSE in the U.S. and to reduce the potential exposure of Americans to the BSE agent. The risk assessment reviewed available scientific information related to BSE and other TSEs, assessed pathways by which BSE could potentially occur in the U.S., and identified measures that could be taken to protect human and animal health in the U.S. The Harvard study concluded that if introduced, due to the preventive measures currently in place, BSE is extremely unlikely to become established in the U.S. Should BSE enter the U.S., the Harvard study concluded that only a small amount of potentially infective tissues would likely reach the human food supply and be available for human consumption.

(2) Land that has an Erodibility Index of greater than 8. This index is based on a field's inherent tendency to erode, from rain or wind, in the absence of cover crop. The Erodibility Index is based on the Universal Soil Loss Equation and the Wind erosion equation, along with a soil's T-value –a measure of the amount of erosion in tons per year that a soil can tolerate without losing productivity. For most cropland soils, T-values fall in the range of three to five tons per acre.
