Applicable state and federal regulations comprising over 60,000 pages are continually being updated. Many of these regulations overlap and are subject to differences in interpretation that often lead to court rulings. Regulations, economic pressures and public perception are forcing companies to rapidly change the way they manufacture products in order to minimize hazardous waste generation.Over 200 million tons of solid hazardous waste are generated annually in the United States. Huge quantities of hazardous waste deposited in landfills, ponds, fields, and other locations require removal or in situ treatment. Common hazardous wastes include: Solvents, acids, bases, heavy metals, pesticides, plating and heat treating wastes. Six major effects of improper hazardous waste management are: groundwater contamination, contamination of surface runoff, air pollution, fire and explosion, adverse health effects via direct contact, and via the food chain.This chapter provides a general overview of federal regulations governing hazardous waste management, as well as a brief review of the types of hazardous waste, waste minimization, and treatment and disposal technologies. Four types of hazardous waste will be discussed here: chemical waste, radioactive waste, infectious waste, and mixed waste. Harold M. Cota Articles http://works.bepress.com/hcota/19 http://works.bepress.com/hcota/19 Mon, 24 Aug 2009 08:27:43 PDT In order to attain and maintain federal and state air quality standards for particulate matter, some local agencies in California have adopted rules and regulations to control emissions from wood burning devices. Some of these rules restricted the use or installation of new masonry fireplaces. The purpose of this study was to begin development of a test protocol that would provide for consistent measurement of particulate emissions from conventional fireplaces and could be useful for compliance determinations or possible certification of a fireplace design or model.A modified California Air Resources Board Stationary Source Test Method 5 was used to determine particulate emissions from a conventional brick fireplace on the California Polytechnic State University campus in San Luis Obispo. The mean total particulate emission rate for five test bums with dual sampling trains was 79.7 grams per hour with a standard deviation of 18.1 grams per hour. An average of 20.2 kilograms of Douglas fir were burned in each fire resulting in an emission factor of 8.6 grams of particulate per kilogram of dry wood burned.EPA Reference Method 28 for the certification of wood heaters was closely followed with slight modifications to account for the physical differences between wood heaters and conventional fireplaces. The results of this study and the recommendations presented here can be used to further develop standardized operating procedures for compliance determinations and/or certification of conventional fireplaces.

This falls squarely in the realm of the Environmental Engineering Profession. Noise, its effects and control, is an important element of a few Graduate Environmental Engineering Programs, but it does not have a role in most undergraduate programs. One objective of this paper is to demonstrate that noise is an issue needing to be addressed in Environmental Engineering Programs and to suggest that making it a requirement at the undergraduate level has merit. Several models including the program at Cal Poly, San Luis Obispo will be discussed.The authors will also share some spreadsheets that undergraduate students have developed in class. Harold M. Cota Conference Proceedings http://works.bepress.com/hcota/17 http://works.bepress.com/hcota/17 Mon, 05 Jan 2009 08:53:22 PST Noise is an is an that affects almost everyone. And even though environmental engineers are often called on to deal with noise-related problems, most of them receive little or no academic training in noise control. This primer suggests why all environmental engineers should know something about noise control, what they need to know, and where they can find the necessary information. Harold M.

Cota Articles http://works.bepress.com/hcota/15 http://works.bepress.com/hcota/15 Mon, 05 Jan 2009 08:53:15 PST From the inception of the National Air Pollution Control program, the U. S. Congress has been mindful of the need and importance of adequate manpower. The challenging technical problems which lie ahead in enforcement, monitoring, testing and research can be effectively dealt with only by individuals with specialized knowledge, skills and experience. In this paper the authors look at undergraduate and graduate training that is being carried out, employment opportunities and the way these may change in the future. A recently completed survey of college level air pollution training in the United States and Canada is included in the report. August T. Rossano Articles http://works.bepress.com/hcota/14 http://works.bepress.com/hcota/14 Mon, 05 Jan 2009 08:53:10 PST A nationwide survey of air pollution control training efforts in the United States at colleges and universities was carried out for the S-ll Education and Training Committee, Air Pollution Control Association. Information from 91 schools having four year or graduate programs and five community colleges was received. Questions include type of course work, backgrounds of participating faculty and students, and eventual placement. At the present time about 70% of those in training are graduate students. It was found that most students taking initial employment in air pollution control activities had the M.S. degree. Recommendations for updating this information are made. Harold M. Cota Articles http://works.bepress.com/hcota/13 http://works.bepress.com/hcota/13 Mon, 05 Jan 2009 08:53:06 PST A survey of academic programs in air pollution control was made. Results from the 127 schools reporting are tabulated by state. Faculty involved in air pollution instruction are identified. Some conclusions and recommendations are presented. Harold M.
