Disposal of Polychlorinated Biphenyls (PCBs); Final Rule, June 29, 1998 (Volume 63, Number 124) [Page 35383-35474]. EPA is amending its rules under the Toxic Substances Control Act (TSCA) which address the manufacture, processing, distribution in commerce, use, cleanup, storage and disposal of polychlorinated biphenyls (PCBs). This rule provides flexibility in selecting disposal technologies for PCB wastes and expands the list of available decontamination procedures; provides less burdensome mechanisms for obtaining EPA approval for a variety of activities; clarifies and/or modifies certain provisions where implementation questions have arisen; modifies the requirements regarding the use and disposal of PCB equipment; and addresses outstanding issues associated with the notification and manifesting of PCB wastes and changes in the operation of commercial storage facilities. This rule also codifies policies that EPA has developed and implemented over the past 19 years. Some activities currently requiring PCB disposal approvals will no longer require those approvals.

Decision Support Software (DSS) Verification Visitor's Day. Albuquerque, September 16. As part of the Environmental Technology Verification (ETV) program, the U. S. Environmental Protection Agency, and the U. S. Department of Energy will be testing and verifying the performance of environmental decision support software (DSS) packages. Many agencies have expressed interest in the performance and potential applications of these packages when tested under real-world situations. Decision support software integrates environmental data and simulation models into a framework for making site characterization, monitoring, and cleanup decisions, (e.g., where to sample, cost/benefit analysis of additional or reduced sampling, and human risk analysis). An effective DSS package integrates, analyzes, and presents environmental information to assist a project manager in developing a cost-effective and defensible, cleanup/monitoring strategy. The verification testing will be conducted at the New Mexico Engineering Research Institute in Albuquerque, New Mexico. To showcase the efforts of this verification, including the technical aspects of the project, a Visitors Day will be held on Wednesday, September 16, 1998. During this day, those in attendance will hear formal presentations by the technology developers and be able to observe application of the software to environmental problems. Advanced registration is required. Contacts: Amy Dindal, 423-574-4863, dindalab@ornl.gov (Visitor's Day) or Terry Sullivan, 516-344-2840, sulliva1@bnl.gov (Technical Information).

Are your waste management and remediation systems Y2K ready? Most people think of Y2K as a computer problem, but there are software programs and embedded chips, which may be vulnerable to the millennium bug, involved in all phases of site investigation and cleanup, waste management facilities, and underground tank operations.

As an example from the utilities industry, the Electric Power Research Institute reports that Y2K testing was conducted on a British power plant's generator temperature control system. The control system's clock was set to just before midnight Dec. 31, 1999. Twenty seconds past midnight, the generator unit tripped (turned off) due to high generator temperature. Turns out that an embedded chip in the control valve for generator cooling was integrated over time for smoothing and when the time moved from ‘99 to ‘00, the processor could not perform the algorithm and so the cooling valve went into fail-safe mode and closed, causing the unit to trip due to high temperature. If this type of thing occurred at many generators, there could be massive electrical outages.

Preparedness for Y2K is now receiving a lot of attention at highest levels of federal government. And a significant federal effort has been launched to deal with the Y2K problem, with two major facets: ensuring that critical federal information and security systems don't fail, and using federal government agencies as messengers about the importance of understanding and attending to the Y2K problem now. Will your pump and treat system operate? Will your monitoring systems function and produce reliable data? Will your waste management facility operate in a manner protective of the environment. Have you begun the process of examining potential Y2K related vulnerabilities associated with the environmental systems you manage?

As part of the Y2K awareness campaign, we are interested in identifying vulnerabilities that may exist in site assessment and remediation operations, hazardous waste landfills, incineration facilities, underground storage tank operations and oil delivery or storage systems. By identifying the possible Y2K problem scenarios, we may be able to help other waste management professionals that had not contemplated a relationship between potential Y2K problems and their environmental protection systems. I invite you to share waste system-related Y2K problem scenarios you foresee similar to the utilities example (scrubbed of any references to specific locations or names). We will post the scenarios on CLU-IN as a service to others in the waste management community. Thank you.
