Editor's Notes:
Topic of the Month: Canada Geese Control Canada Geese cause significant problems in ponds and lakes. The Fish and Wildlife Service estimated a population of 4.5 million in 2006, with a 10-17% increase in their populations yearly. They live up to 24 years and have an average nest size of 3 to 6 eggs, up to a maximum of 12 eggs. Canada Geese can eat 4 pounds of grass and excrete up to 3 pounds of waste per day. This can cause excessive nutrient loading, leading to algal blooms and excessive plant growth in lakes and ponds. More...

Changes in Nutrient and Sediment Concentrations in Streams and Rivers of the United States, 1993-2003 A report issued by the U. S. Geological Survey’s National Water Quality Assessment Program states that phosphorus and nitrogen concentrations have stayed relatively stable in half of the assessed streams between 1993 and 2003.

Flexing the Infiltration Muscle: What’s the Role of ET? Most states consider infiltration as the ultimate solution for stormwater management, since it reduces stormwater runoff, filters the water through the soil and recharges the groundwater table. However, there is very little discussion on evapotranspiration (ET). More...

Top Ten Hot Trends in Greenroof Design 2009 2009 Open Space Plan – New York State This plan, recently released by New York State’s Department of Environmental Conservation, provides a comprehensive guide for achieving New York’s conservation goals. The 2009 plan contains a list of 135 priority conservation projects and over 300 internet links to valuable information and resources. Environment DEC, July 2009 http://www.dec.ny.gov/environmentdec/55779.html
EPA State Review Framework: Compliance & Enforcement through State Government The Environmental Protection Agency is providing online comprehensive reports on water quality enforcement data for all 50 states. The reports provide data on federal and state enforcement of National Pollutant Discharge System Permits (NPDES). There are also new tools for the public to search and review the data used to generate these reports. http://www.epa.gov/compliance/state/srf/index.html
Network Discharge Monitoring Reports (NetDMR) – EPA This web-based electronic reporting tool will reduce paper reporting. National Pollutant Discharge Elimination System (NPDES) permitted facilities can use this tool to submit monthly discharge monitoring reports (DMR). This tool is currently available for facilities in the District of Columbia, Louisiana, Massachusetts, New Hampshire, Texas, Utah, and the Gulf of Mexico (offshore rigs). Additional states are expected to be added to the list within a year.
Invasive Species Expert Directory This new resource provides experts in the field of invasive species. Select a state, and this tool will give you a list of contacts with specifics about their background. http://www.anstaskforce.gov/experts/search.php
Technical Report, Stormwater BMPs in Virginia’s James River Basin: An Assessment of Field Conditions & Programs (part of the Extreme BMP Makeover Project) A stormwater Best Management Practice (BMP) performance study was completed of nearly 200 stormwater BMP’s in urban areas throughout the James River watershed. This technical report describes survey results and recommendations regarding design, construction, and maintenance issues. This is part of the Extreme BMP Makeover Project, which is focused on improving pollutant reduction achieved by BMPs in the James River watershed. http://www.cwp.org/Resource_Library/Center_Docs/SW/ExtremeBMP/extrmbmp_tech_rprt09.pdf

Habitat Happenings This new web feature provided by the Pennsylvania Game Commission focuses on habitat management practices. Every week a new journal entry or report will be provided to show what they do on state game lands and lands enrolled in the agency’s cooperative public lands programs. The first participants featured will be from the Southeast Region. http://www.pgc.state.pa.us/pgc/cwp/view.asp?a=528&q=176508
Center for Watershed Protection Webcasts – Stormwater Retrofitting A webcast will be provided on “Stormwater
Retrofitting” on October 14, 2009. It will focus on restoring watersheds
through stormwater retrofitting practices featured in their Urban Stormwater
Retrofit Practices manual. They will also discuss the cost and pollutant
removal of stormwater retrofits. Registration will open in August.
If you missed their June webcast, “Managing Stormwater in the Age of Budget Cuts”, it is free and available at http://www.cwp.org/Webcasts/#archive Bad Water 2009: The Impact on Human Health in the Chesapeake Bay Region The Chesapeake Bay Foundation released this report regarding the health of the Chesapeake Bay region and its impact on human health. It features concerns such as harmful bacteria, mercury contamination of seafood and nitrates in ground water. It is based on interviews conducted with leading scientists and health experts. The report includes three case studies from Pennsylvania, Maryland and Virginia. http://www.cbf.org/Page.aspx?pid=521&srctid=1&erid=67967
Urban BMP Performance Tool This EPA website is useful for stormwater professionals to aid in selecting effective stormwater Best Management Practices (BMPs). It provides about 220 studies assessing over 275 BMP’s. http://cfpub.epa.gov/npdes/stormwater/urbanbmp/bmpeffectiveness.cfm
