EPA 1s deueloping an RCRA Hazardous Waste Minimlzation NatIonal Plan that will serue as the basfsfor an ouerall natlonal policy on hazardous waste management. The Plan wlll place Its hlghest prlority on source reduction, followed by recycllng. In thls article, the Chief of the EPA’s Waste Minimlzatlon Branch describes the Agency’s Draft National Plan and requests comments from readers on the is...

It is now apparent that classical T Tauri-like outflows commonly accompany the formation of young brown dwarfs. To date two optical outflows have been discovered and results presented in this paper increase this number to three. Using spectro-astrometry the origin of the LS-RCrA 1 forbidden emission lines in a blue-shifted outflow is confirmed. The non-detection of the red-shifted component of ...

Monsanto has in fact submitted false information to EPA which directly resulted in weakened regulations under RCRA and FIFRA since these regulations do not take into account tetrachlorinated dioxin contamination in trig, tetra, and pentachlorophenols, as well as 2,4-dichlorophenol and its phenoxy acetate (2,3-D, a currently used herbicide). In addition, Monsanto's failure to report dioxin conta...

Of the 12 billion tons of waste generated annually in the United States; less than 10% is defined as hazardous under the provisions of RCRA. This paper summarizes the data available on some of the wastes that are defined as non-hazardous. These wastes include industrial non-hazardous waste, and several types of wastes that are currently exempted from hazardous waste regulations, such as oil and...

Vapor intrusion is the migration of volatile compounds from the subsurface into overlying buildings or structures. This document provides an overview of the process to be used to assess the potential risk posed by vapor intrusion at sites undergoing investigation and cleanup within the Minnesota Pollution Control Agency (MPCA) Superfund Program, Resource Conservation and Recovery Act (RCRA) Cor...

The Resource Consumption and Recovery Act (RCRA), 1976, encourages waste minimization via practices like source reduction and solvent recycle. Waste streams treated with the orthodox end-of-pipe treatment options like thermal incineration, chemical oxidation etc. has to be reported as RCRA hazardous. To avoid strict environmental regulations imposed on all such effluent streams, this paper expl...

This paper is the first in a proposed series of papers that will try to answer a question commonly directed to the Department of Energy: “How is risk used to make decisions in the Environmental Management (EM) program?” This paper summarizes the role that human health and safety risk plays in DOE cleanup decision-making under CERCLA and RCRA, two main regulatory drivers behind DOE cleanup effor...
