EPA SITE Program. The EPA Superfund Innovate Technology Evaluation (SITE) Program seeks cooperative projects with hazardous waste sites that are in need of full-scale demonstrations of innovative treatment technologies. SITE offers a mechanism for independent third party evaluation of innovative technology performance and cost. The site program is financially responsible for preliminary treatability studies, test plan preparation, sampling, sample and data analysis and report writing of the demonstration results. This solicitation is directed toward owners/managers of private sites or state and federal government agencies that have the financial or regulatory responsibility for on site hazardous waste remediation. Copies of the solicitation and application may be downloaded at http://www.epa.gov/ORD/SITE. For more information contact Randy A. Parker parker.randy@epa.gov (513) 569-7271.

DoD ESTCP. The Department of Defense, through the Environmental Security Technology Certification Program (ESTCP), will be funding demonstration projects for treatment of perchlorate in drinking water. The objective of this effort is to evaluate alternative technologies that can significantly reduce the costs of removing perchlorate for large-scale drinking water treatment. ESTCP intends to fund multiple demonstration projects through this competitive selection process. The demonstrations will be conducted at a number of selected public water supply utilities in southern California that have been impacted by perchlorate. The due date for these pre-proposals is November 18, 2004.

Strategy to Ensure Institutional Control Implementation at Superfund Sites (OSWER Dir. 9355.0-106). This document sets forth EPA’s strategy (Strategy) for ensuring that institutional controls (ICs) are successfully implemented at Superfund sites, with an emphasis on evaluating ICs at sites where all construction of all remedies is complete (construction complete sites).1 This Strategy will serve as a roadmap for EPA regional and headquarters personnel in preparing Region specific action plans and conducting the work necessary to ensure the proper implementation of ICs at Superfund sites. This work includes gathering and entering information in the Institutional Controls Tracking System (ICTS), evaluating the data generated through ICTS, prioritizing and conducting site-specific followup activities, building the capacity to better manage and review IC information, and coordinating with other interested parties (September 2004, 17 pages).

ESTCP Cost and Performance Report: Man Portable for the Multi-Sensor Towed Array Detection System (UX 9811). This evaluation report was produced by the DOD Environmental Security Technology Certification Program (ESTCP). The MTADS addresses all aspects of the Tri-Service Requirements for land-based buried UXO. It is capable of detecting all classes of buried UXO at their maximum likely penetration depths. The system correctly locates buried targets, determines their burial depths, classifies the likely ordnance size, and provides for future target way pointing, as well as creating geographical information system (GIS)-compatible target output maps and sorted target tables. The man portable adjuncts extend this capability into areas of rugged terrain and areas with poor sky visibility (June 2004, 85 pages).

Remediation Process Optimization: Identifying Opportunities for Enhanced and More Efficient Site Remediation (RPO-1). This document was produced by the Interstate technology and regulatory Council (ITRC). It provides practical information and guidance on how to systematically evaluate and manage uncertainty associated with the remediation process by using RPO as a tool. Its primary goal is to provide information and tools to help ensure that the remediation process is progressing toward site cleanup objectives that are both acceptable and feasible and that selected remediation approaches attain those objectives and remain protective of human health and the environment. This document provides guidance on what could and should be included in an effective RPO proposal or program, including what RPO is, the regulatory framework that RPO must operate within, and references that provide examples of successful RPOs and resources for further examination of RPO.(September 2004, 156 pages).
