The officials of Sunnyside High School District and a United States Representative have expressed great concerns regarding the potential adverse health effects due to beryllium exposure in the vicinity of Brush Ceramic Products. The Arizona Department of Health Services was asked to determine whether beryllium released from Brush Ceramic’s plant poses a health threat to school children and employees, and residents in the vicinity of the facility.

This health consultation evaluates results of irrigation well samples collected by the Arizona Department of Environmental Quality in October 2003. Previous results obtained by the Blue Ridge Elementary School District in the summer of 2003 indicated trichloroethylene levels above the U.S. Environmental Protection Agency’s Maximum Contaminant Level. In addition, the most recent (2002) Annual Water Quality Report from the drinking water supplier, Arizona Water Company, was reviewed. A previous health consultation (Blue Ridge Elementary School, Lakeside, Navajo County, Arizona Health Consultation-April 30, 2003) reviewed environmental conditions at Blue Ridge Elementary School. Parents and school staff were concerned that environmental exposures were causing students to be absent from school. Drinking water quality reports, indoor air quality data, food safety, environmental sanitation records, student attendance rates, and the results of an annual parent satisfaction survey were evaluated in the consultation. Arizona Department of Health Services concluded that environmental conditions at Blue Ridge Elementary School posed no apparent public health hazard, and that attendance rates were similar to statewide attendance rates. As part of the 2003 health consultation, ADHS requested that the school district conduct water sampling from the on-site irrigation water wells for the school grounds. Those sampling results were not available when the 2003 health consultation was completed.

The purpose of this health consultation is to evaluate the air monitoring conducted by the Arizona Department of Environmental Quality at Mary McLeod Bethune School (Phoenix, AZ) and evaluate the potential impact on public health. The air monitoring data includes particulate matter and metals. The ADEQ’s primary objective of this air sampling is to provide an understanding of the hazardous air pollutants in the Phoenix area.

This report evaluates the potential exposure pathways associated with vermiculite concentrate processing activities at the Ari-Zonolite facility. The site is located in the near downtown area of Glendale, approximately ½ mile from the city hall, downtown shops, and other buildings. The former Ari-Zonolite facility received vermiculite from the Libby, Montana, mine. From 1951 to 1964, the site was leased the site to the Ari-Zonolite Company. Following the removal of the vermiculite concentrate processing equipment in 1964, several businesses have occupied the site. None of these businesses were involved in vermiculite processing activities. The last occupant of the former vermiculite processing building was an automotive restoration business, which vacated the site in 2002.

The theory of factor market distortions deals largely with taxing inputs. However, input subsidies are not only common in manufacturing. For example, U.S. agriculture is heavily dependent on input subsidies.
If water subsidies in the production of California cotton were removed, along with commodity payments, production of cotton in California would likely cease. Likewise, transportation subsidies were common in both the U.S. and Canada, and still prevail in the U.S.

After twenty years of Ag Mediation’s assistance to the American rural areas, there are a number of key developments which I would like to highlight for the Bureau of Land Management and others interested in mediation and dispute resolution. These include background, law, and efforts by states and federal government to focus on mediation as a way of settling disputes. Finally, I would like to enumerate the lessons we have learned.

Contains a dynamic programming algorithm for projecting policy parameters based on a storage model of international markets featuring uncertainty, forward-looking rational expectations and non-negative storage. This algorithm is motivated by the need for a non-analytical solution to the competitive equilibrium in a storage model of U.S. and foreign cotton policy regimes. Obtaining an analytical solution is difficult, except in a limited number of special cases. The numerical solution algorithm essentially consists of multiple nested numerical approximations that reach convergence simultaneously when the relationship between domestic storage and expected farm price achieves stationarity. Given the stationary relationship between storage and expected farm price, we then run the model forward in time (given a sequence of annual realized yield disturbances) under alternative policy regimes representing FACT and FAIR.

This paper provides a methodology that can be used to weigh the costs and benefits of precision agriculture in the measurement and application of variable-rate production technology. Empirical estimates of the economic value of precision farming in the form of variable-rate fertilizer application to corn fields in the mid-western United States are calculated and compared to the current cost of investing in this technology. The results of this study indicate that the use of precision technology in the application of fertilizer for corn production in the United States is not profitable over a relatively wide range of corn prices, nitrogen prices, and agronomic differences in soil characteristics.

In the “Attacking Global Barriers” or “Phoenix Project”, the Royal Agricultural College and Arizona State University East are working together to insure we have an exciting future in the food management area. This abstract outlines the progress of the Phoenix Project and updates IAMA on the Second Congress of the Phoenix Group. The “Attacking Global Barriers” project focuses on educational and academic issues, and impediments to student movement in the academic year 1998/99. It updates earlier reports to IAMA and gives an overview of the first and second congresses with the American and European Universities.

In 1995/96, the government of Turkey imposed an export tax of 20 cents/kg on Aegean cotton and an ad-valorem import duty of one percent on non-aegean cotton. The simulation results for the Aegean market indicate that consumers gained $44.5 million in consumer surplus because the export tax reduced the purchase price of Aegean cotton. The Turkish government extracted export tax revenue equal to $11.6 million, but provided water, fertilizer, and credit subsidies equal to $22.2 million. Producers lost $35 million in producer surplus due to the lower domestic price caused by the export tax. However, while these numbers represent large transfers from producers to consumers, the net inefficiency due to government distortions amount to only $1.14 million in the Aegean market. Adding this number to the dead-weight loss of only $790,000 obtained from the non-Aegean market simulation, the net inefficiency caused by government intervention in Turkish raw cotton markets was only $1.93 million in 1995/96. If one considers that cotton producers in Turkey realized gross revenue of over $1.4 billion across all markets in 1995/96, the results of the analysis seems to indicate that the income transfer associated with Turkish government programs is not very inefficient.
