Water Headlines for July 20, 2006

Benjamin H. Grumbles
Assistant Administrator
Office of Water

Water Headlines is a weekly on-line publication that announces publications, policies, and activities of the U.S. Environmental Protection Agency’s Office of Water.

In This Week’s Water Headlines:

Comment Period Extended for Proposed Water Transfers Rule

The comment period for the NPDES Water Transfers Proposed Rule has been extended 14 days to August 7, 2006. The original due date for comments was July 24, 2006. Numerous stakeholders requested an extension to the comment period.

The proposed rule would clarify that the transfer or conveyance of water from one body of water to another body of water is excluded from regulation under the Clean Water Act’s NPDES permitting program. Whether a permit is needed or not has been at issue in numerous court cases in recent years. The proposed rule would define a water transfer as an activity that conveys waters of the United States to another water of the United States without subjecting the water to intervening industrial, municipal, or commercial use.

EPA Publishes Draft Guidance to Control Nonpoint Source Pollution from Hydromodification

EPA has posted draft guidance on its Web site that will provide technical assistance to states, territories, tribes, and municipalities for managing hydromodification and reducing nonpoint source (NPS) pollution of surface and ground water. The document describes examples of practices that can be used to reduce NPS pollution from activities associated with channelization, channel modification, dams, and streambank and shoreline erosion. Implementation of the guidance will result in increased use of scientifically sound, cost-effective hydromodification management measures, and will support states in their efforts to implement their Nonpoint Source Control Programs. The draft document is available for review/comment at: http://www.epa.gov/owow/nps/hydromod/index.htm. For additional information contact Chris Solloway at 202-566-1202.

AQUATOX Training Workshop in Philadelphia, October 2006

EPA is sponsoring an AQUATOX training workshop on October 24-26 in Philadelphia. AQUATOX is a PC-based simulation model for aquatic ecosystems that covers eutrophication, chemical fate, bioaccumulation, and ecotoxicology. The course is a detailed overview of the model that allows ample time to work with it in a lab setting. There is no charge for the workshop, but attendance is limited. We require that you register before the course. You can get more information at our AQUATOX training page on the Internet at www.epa.gov/waterscience/models/aquatox/training/.
