Petroleum Brownfields Web Site. EPA's new petroleum brownfields web site is designed to make information more accessible for those working to foster the cleanup and reuse of petroleum-impacted properties. It provides easy access to information that both new users and those familiar with brownfields will find useful. For instance, the Web site provides access to: "how to" guides, ways to find petroleum brownfields sites, assessment and cleanup information, financial guides and EPA Brownfields program and grants information, public/private partnership information, and sustainability and petroleum brownfields. More information at .

Petroleum Brownfields: Developing Inventories (EPA 510-R-09-002). This publication is intended as a tool to help states, tribes, EPA Brownfields Assessment grant recipients, and others develop an inventory of relatively low-risk, petroleum-contaminated brownfield properties. The publication has three sections. Section I identifies petroleum brownfields inventories as a tool for building and promoting a brownfields program. Section II outlines considerations for building an inventory, and Section III discusses best practices from stakeholders that have implemented a petroleum brownfields inventory (May 2009, 34 pages).

EPA Dataset/Databases for Ecological Risk Assessment of Contaminated Sites. To assess the potential for risk from contaminated sediments and to help determine contamination levels for remedial designs, EPA's Land Research Program has developed several ecological risk assessment tools including: 1) Biota-Sediment Accumulation Factor Data Set, which can be used to evaluate the transfer of chemicals from sediments into the aquatic food chain; 2) PCB Residue Effects (PCBRes) Database, an abundance of information for risk assessors to use for correlating polychlorinated biphenyls (PCBs) and other dioxin-like compound residues with toxic effects and developing Toxicity Reference Values (TRVs); and 3) ECOTOX Database, for use when risk assessors and managers need to develop TRVs for sediment sites that have contaminants other than, or in addition to, PCBs and dioxins and provides ready access to single-chemical toxicity information for aquatic and terrestrial life. Each of these tools facilitate a scientifically defensible risk assessment, improve the decision-making ability of risk managers at Superfund and other contaminated sites, and facilitate successful remediation efforts.

Comparison of Pumped and Diffusion Sampling Methods to Monitor Concentrations of Perchlorate and Explosive Compounds in Ground Water, Camp Edwards, Cape Cod, Massachusetts, 2004-05. Comparison of the concentrations of perchlorate, RDX, and HMX in diffusion samplers placed in wells against concentrations in samples collected by low-flow pumped sampling indicates generally good agreement between the pumped and diffusion samples for concentrations of the subject contaminants. The concentration differences indicate no systematic bias related to contaminant type or concentration level (September 2008, 26 pages). View or download at .

SUBR:IM (Sustainable Urban Brownfield Regeneration: Integrated Management) - An Overview. In July 2003, the SUBR:IM (Sustainable Urban Brownfield Regeneration: Integrated Management) consortium began its research into brownfield regeneration in the aftermath of the UK government's publication of its Sustainable Communities Plan (2003). With the completion of the project in 2007, brownfield regeneration now occupies even greater importance in national policy debates. Despite being an academically-based research project, we worked closely with many in the brownfield community and were keen to put the research outcomes into forms more accessible to practitioners. To this end, we have produced a series of 12 bulletins, published and circulated by Contaminated Land: Applications in Real Environments (CL:AIRE) (April 2009, 2 pages). View or download at .

Incentives for Greener Cleanups. The mission of the Association of State and Territorial Solid Waste Management Officials (ASTSWMO) Greener Cleanups Task Force is to facilitate cleanup decisions that increase net environmental benefits of remediation and contribute to site sustainability. To achieve this mission the Task Force identified nine initiatives that it believes will incentivize entities to employ greener remediation approaches at underground storage tank, Brownfields, Federal Facility, RCRA, Superfund, and State site cleanups. Greener practices can be perceived as costly, time consuming, and less certain in their outcomes than conventional remediation. To overcome these perceptions, incentives are needed for parties who perform site cleanups and the regulatory oversight agencies that oversee these activities (June 2009, 17 pages).
