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.
See http://www.epa.gov/oust/fedlaws/epact_05.htm#Drafts to view the
drafts and obtain details about how and where to submit comments.

ITRC Characterization, Design, Construction and Monitoring of Bioreactor
Landfills – 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

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
the load reductions required to meet water quality standards, developing
management measures, and tracking progress once the plan is implemented.

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
license EPA technologies and develop new products to strengthen
protection. The site contains a searchable database of EPA patents
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
such as CERCLA and RCRA, as well as on environmentally pertinent topics
such as Coatings, Explosives Safety, the Federal Facilities Compliance
(FFCA), Military Munitions Rule (MMR), and Solvents Alternatives. Quick
access to online resources such as TOXNET, EPI Suite, and the Periodic
Table increases efficiency in finding information. Register on the EKAT
demo site to test out the system. For more information and to register
