Special Notice  
Underground Storage Tanks Program Draft Guidelines for Comment.  The  
U.S. EPA Office of Underground Storage Tanks (OUST) has recently  
published for comment three draft guidelines to implement Title XV,  
Subtitle B of the Energy Policy Act of 2005, which focuses on preventing  
underground storage tank releases. EPA, in conjunction with states and  
other stakeholders, developed these grant guidelines for state  
storage tank programs.   EPA will accept comments on these three draft  
guidelines beginning May 25, 2006 for 30 days, ending June 24, 2006.

ITRC Characterization, Design, Construction and Monitoring of Bioreactor  
– June 13. Bioreactors are landfills where controlled addition of  
liquid wastes, sludges, or water accelerates the decomposition of waste  
landfill gas generation. This training, based on the ITRC's  
Design, Construction, and Monitoring of Bioreactor Landfills (ALT-3,  
teaches the principles used to make critical decisions during  
operating, and monitoring a bioreactor landfill. This training also  
provides a  
general understanding of the biological degradation of solid wastes  
aerobic and anaerobic waste conditions and the degradation products  
associated with each process. For more information and to register,

ITRC Permeable Reactive Barriers: Lessons Learned and New Directions –  
June 15.  
This training presents updated information regarding new developments,  
approaches, and lessons learned in the application of PRBs to treat a  
variety of  
groundwater contaminants. The information will be presented by reviewing  
the approaches and results at several sites where PRBs have been  
The training is based on the ITRC guidance document titled Permeable  
Barriers: Lessons Learned / New Directions (PRB-4, 2005). For more

New Documents  
Making Data Meaningful: A Guide to Writing Stories About Numbers.  This  
was prepared within the framework of the United Nations Economic  
for Europe (UNECE) Work Session on Statistical Dissemination and  
Communication. It is intended as a practical tool to help managers,  
and media relations officers use text, tables, graphics and other  
information to  
bring statistics to life using effective writing techniques. It contains  
guidelines and examples – but not golden rules. This publication  
that there are many practical and cultural differences among statistical  
and that approaches vary from country to country (2005, 25 pages).  View

Attenuation of Nitrate in the Sub-surface Environment (SR SC030155/SR2).  
This Science Report was published by the UK Environment Agency.  It  
provides a literature review of nitrate attenuation mechanisms as they  
occur in the sub-surface environment. It discusses the chemical  
under which attenuation occurs and the hydrogeological environments  
within which this has been observed.  The processes controlling nitrate  
attenuation in the soil zone are well understood.  However, for the  
environment beneath this zone, relatively little is known about the  
geochemical conditions that determine whether denitrification will take

Draft Handbook for Developing Watershed Plans to Restore and Protect Our  
Waters (EPA 841-B-05-005).  This draft guide to watershed management was  
produced by the EPA Office of Water.  Its purpose is to help various  
organizations develop and implement watershed plans.  This handbook  
in-depth guidance on quantifying existing pollutant loads, developing  
estimates of  
the load reductions required to meet water quality standards, developing  
management measures, and tracking progress once the plan is implemented.  
is accepting comments and suggestions on the document through June 30,

EPA TechMatch.  The U.S. EPA has partnered with the West Virginia High  
Foundation Consortium to create a new website call EPA Techmatch to  
licensing opportunities for EPA patents.  Its goal is to encourage  
entrepreneurs to  
license EPA technologies and develop new products to strengthen  
protection.  The site contains a searchable database of EPA patents  
across all  
media. You may also browse diverse technologies available for licensing  
cooperative research partnerships.  Third-party independent analyses of  
commercial potential of the technologies also are available.   For more

Environmental Knowledge and Assessment Tool (EKAT) – The development of  
EKAT was funded by the U.S. Marine Corps.   The goal of EKAT is to help  
remediation and hazardous waste professionals save time and effort  
on projects related to remediation, brownfields, site characterization,  
hazardous waste, and clean up issues.  EKAT contains a wealth of  
regulatory information. There are online tools to screen chemicals for  
and state regulatory information, including CERCLA, RCRA, CAA, and CWA.  
Get NIOSH REL and OSHA PEL information for chemicals in air. EKAT also  
includes Hazardous Waste Guides, Physical and Chemical Properties Guides  
and Toxicology Guides to help with risk assessments. EKAT summarizes,  
categorizes and links to highly useful resources on: major federal
