if solid wastes are not collected and disposed properly, can cause environmental pollution which affect human health, animals and plants. also aesthetic aspect of solid waste disposal is important. therefore proper management is necessary. this study was carried out for the identification and classification of solid waste produced by oil drilling company temporary camps based on rcra act and un...

Each year, 115 million tons of coal combustion products (CCPs) are produced in the United States, 90% of them by electric utilities. CCPs are mainly ash, usually mixed with wastes from pollution control scrubbers (consisting of particulate matter and neutralizing lime), coal piles, and other sources. In 1993, the U.S. Environmental Protection Agency (EPA) exempted pure coal ash from Subtitle C ...

The DOE complex contains many tank sludges contaminated with mercury. The high pH of these tank sludges typically fails to stabilize the mercury, resulting in these radioactive wastes also being characteristically hazardous or mixed waste. The traditional treatment for soluble inorganic mercury species is precipitation as insoluble mercuric sulfide. Sulfide treatment and a commercial mercury-st...

This project was undertaken to complement a s t u d y of t h e occurrence of p a t h o g e n s i n distributed and marketed (D 81 M) municipal sludge products. The purpose was to provide a data base of priority pollutant metals and organics from sludges produced at facilities in 26 cities across the U.S. In addition, efforts were made to characterize the major organic components in sample extra...

INTRODUCTION The acid rain provisions of the 1990 Clean Air Act Amendments (CAAA) provide new incentives for the development of power generation technology with low SO 2 emissions. Detailed evaluations of possible NO x and air toxics emission limits also are required by the CAAA in the next few years. Furthermore, reauthorization of other key environmental legislation, such as the Clean Water A...

INTRODUCTION Underground storage tanks containing hydrocarbonbased fuels are found worldwide. Many of these underground storage tanks are known to have leaks, allowing gasoline, diesel or other fuels to contaminate the surrounding soil. As of 1992, there were two million underground tanks being monitored for leaks and an additional three million not monitored for leaks within the United States ...

INTRODUCTION Underground storage tanks containing hydrocarbonbased fuels are found worldwide. Many of these tanks have leaks, allowing gasoline, diesel, oil, or other hydrocarbon materials to contaminate the surrounding soil. In 1992, only 2 million of the 5 million tanks in the U.S. were monitored for leaks. However, underground storage tanks represent only one of many sources of hydrocarbon c...

In your letter of January 31,1990, you asked us to evaluate the quality of the Environmental Protection Agency (EPA) data that will be used to determine the need for mandatory waste minimization requirements. We presented initial fmdings in response to this request in August 199 1. This report presents our detailed findings on this issue; that is, our assessment of (1) the degree and causes of ...
