EPA's Arsenic Rule: The Benefits of the Standard Do Not Justify the Costs

The U.S. Environmental Protection Agency recently finalized a rule that would reduce the maximum allowable level of arsenic in drinking water by 80 percent. While arsenic is thought to be essential for the human body at low levels, it can cause cancer when consumed at higher concentrations for extended periods of time. This regulatory analysis evaluates the benefits and costs of the EPA's rule. On the basis of currently available information, we find that the EPA's standard cannot be justified on economic grounds. We estimate that the costs of the final rule will exceed the benefits by about $190 million annually. We also find that the rule probably will result in a net loss of life. We find that the rule probably will result in a net loss of life. The direct effect of the rule will be to save about ten lives annually in the future. After taking into account the indirect impacts of the cost of the rule on items like health care expenditures, however, we find that the rule is likely to result in a net loss of about ten lives annually. A question that the rule does not examine carefully is whether other regulatory alternatives could result in positive net benefits. We explore the option of targeting specific water systems and find that this strategy is unlikely to be very helpful. Instead of regulating more stringently now, the agency should wait until more information becomes available over the next few years. Such a strategy would have the advantage of avoiding large capital expenditures until the time that evidence suggests that risks posed by arsenic in drinking water are significant.

Should You Be Allowed to Use Your Cellular Phone While Driving?

Regulation of the use of cellular phones by individuals while driving is now commonplace outside the United States and has been proposed in a number of jurisdictions in the United States. There is growing concern that using cellular phones while driving leads to increases in accidents and fatalities. This paper provides an economic analysis of regulatory options for addressing cellular phone usage by drivers of vehicles. While large uncertainties surrounding both benefits and costs exist, a key conclusion is that banning drivers from using cellular phones is a bad idea. Our best estimate is that the costs of a ban are likely to exceed benefits by about $20 billion annually. Less intrusive regulation, such as requiring the use of a hands-free device that would allow a driver to use both hands for steering also is not likely to be economically justified.

Hydrogen Enriched Natural Gas as a Clean Motor Fuel (CONTINUATION OF 7863 ABANDONED)

A fuel mixture is disclosed. In a preferred embodiment, an alternative gaseous fuel for operating a combustion engine includes approximately 21 to 50% Hydrogen and the rest natural gas constituants such as combinations of Methane, Carbon Dioxide, Nitrogen, Ethane, Propane, Iso-Butane, N-Butane, Iso Pentane, N-Pentane, and Hexanes Plus. Current production engines without any substantial modifications can take this alternative fuel. This alternative fuel is lean burning and emits emissions that are below current legal standards

Hydrogen Enriched Natural Gas as a Motor Fuel with variable Air Fuel Ratio and Fuel Mixture Ratio Control (CIP OF 7863 ABANDONED)

A hydrogen and natural gas fuel mixture for internal combustion engines is provided for vehicle engines such as those used in standard production engines for automobiles, trains and lawn mowers. The gaseous fuel for operating a vehicle combustion engines includes approximately 21 to 50% Hydrogen and the rest natural gas constituents such as combinations of Methane, Carbon Dioxide, Nitrogen, Ethane, Propane, Iso-Butane, N-Butane, Iso Pentane, N-Pentane, and Hexanes Plus. A fuel mixture of approximately 28 to 36 percent Hydrogen and a air fuel equivalence ratio of approximately 0.625 is an extreme lean burn condition that yields hydrocarbon emission levels of less than approximately 104 ppm (0.84 hm/hp hr.). Current internal combustion engines that are in mass production can take this alternative fuel without any substantial modifications to their systems. This alternative fuel is lean burning and emits emissions that are below current legal standards. The novel fuel mixture can be use

Assessing Regulatory Impact Analyses: The Failure of Agencies to Comply With Executive Order 12,866

Assessing the Quality of Regulatory Impact Analyses

This study provides the most comprehensive evaluation of the quality of recent economic analyses that agencies conduct before finalizing major regulations. We construct a new dataset that includes analyses of forty-eight major health, safety, and environmental regulations from mid-1996 to mid-1999. This dataset provides detailed information on a variety of issues, including an agency's treatment of benefits, costs, net benefits, discounting, and uncertainty. We use this dataset to assess the quality of recent economic analyses and to determine the extent to which they are consistent with President Clinton's Executive Order 12866 and the benefit-cost guidelines issued by the Office of Management and Budget (OMB). We find that economic analyses prepared by regulatory agencies typically do not provide enough information to make decisions that will maximize the efficiency or effectiveness of a rule. Agencies quantified net benefits for only 29 percent of the rules. Agencies failed to discuss alternatives in 27 percent of the rules and quantified costs and benefits of alternatives in only 31 percent of the rules. Our findings strongly suggest that agencies generally failed to comply with the executive order and adhere to the OMB guidelines. We offer specific suggestions for improving the quality of analysis and the transparency of the regulatory process, including writing clear executive summaries, making analyses available on the Internet, providing more careful consideration of alternatives to a regulation, and estimating net benefits of a regulation when data on costs and benefits are provided.

Job Advertisements for Recent Graduates: Advising, Curriculum, and Job-seeking Implications

Despite the proliferation of job advertisement analysis studies in the past 30 years, new studies are needed all the time to reflect the current state of the job market for LIS professionals. Using traditional content analysis methods, a study in spring 2009 at the University of Maryland of over 1,000 job ads for new graduates revealed that most jobs are in academic libraries and archives; average salaries rose last year; the highest salaries are in government; personal attributes such as communication, service orientation, collaboration and cooperation, and team capabilities are highly desired; and many entry-level ads request some experience. Very few call for a second master's degree. This study will be useful for faculty advising and conducting curriculum studies, as well as new graduates in the job market
