Report of the NICOLE Workshop: Redevelopment of Sites - the Industrial Perspective. The restructuring of European economies, including the migration of manufacturing to Asia, has resulted in many underused, derelict and contaminated industrial sites. At the same time land demand, principally lead by housing, has made many of these urban sites into attractive assets. The owners of these sites would like to realize the value of these assets and at the same time avoid any future risk of liability. This NICOLE report summarizes the papers delivered at this meeting along with a discussion based on the points raised during the meeting. The workshop reviewed: Drivers for redevelopment of sites for government municipality industry redevelopers; Management of liability; Case studies; and Tools and communication (August 2007, 34 pages).

European Brownfield Revitalisation Agenda. There are many examples of good practice that have produced positive results from brownfield site project redevelopment across Europe. Much of this information is a result of individual EU funded projects but these have not necessarily been brought together to build up a body of collective experience. There is an opportunity to bring together best practices and the various tools that have been developed to create the best opportunities for an integrated approach for the future redevelopment of Brownfield sites. Policy makers and developers should be supported through a conduit of best practice, the collation of information, and a network of specialists with practical experience in the field. The main objective of the EUBRA Agenda is to support policy makers and program managers in setting priorities in future national and international funding programs (Summer 2007, 24 pages).

European Environment Agency: Progress in management of contaminated sites (CSI 015). The EEA monitors a number of environmental indicators across the EU. One of these is: Progress in management of contaminated sites. Soil contamination requiring clean up is present at approximately 250,000 sites in the EEA member countries, according to recent estimates. And this number is expected to grow. Potentially polluting activities are estimated to have occurred at nearly 3 million sites (including the 250000 sites already mentioned) and investigation is needed to establish whether remediation is required. If current investigation trends continue, the number of sites needing remediation will increase by 50% by 2025 (August 2007). Read online at .

Long-Term Monitoring Optimization (LTMO) Training, Seattle, October 17-18. EPA is partnering with the U.S. Army Corps of Engineers to provide state and federal regulators with information about new methods of optimizing groundwater monitoring programs. The training will be held at the EPA Region 10 Office in Seattle, WA on October 17 and 18, 2007. Responsible parties, Federal Facilities, and EPA have used LTMO methods at more than 100 sites nationwide and are likely to use them at more sites in the future. The methods are used to support decision making regarding optimal location and frequency of groundwater monitoring and to support changes to existing monitoring networks. As a result, it is important for regulators to be familiar with LTMO methods and technical support mechanisms such that appropriate decisions can be made. The training includes a 1-day lecture on a variety of qualitative and quantitative methods including: the Monitoring and Remediation Optimization System (MAROS); the Geostatistical Temporal-Spatial (GTS) algorithm; and the Three-Tiered Monitoring Network Optimization (MNO) approach. A 4-hour hands-on training sessions with the MAROS software program will be offered on the second day for a limited number of attendees. While the training is designed primarily for state and federal regulators, federal facilities cleanup managers, potentially responsible parties (PRPs), and contractors are welcome to participate at no cost. State and federal regulators will receive registration priority. For details about this training and to register, visit .
