Ecosystem Services Valuation: Tools And Case Studies
Quantifying Ecosystem Services, Assessing Man-Made Impacts
Robert McKane, USEPA Office of Research and Development
Natural and managed ecosystems provide a multitude of resources and services vital to human well-being ? provisioning of food, fiber, clean water and air, habitat for fish and wildlife, recreational opportunities, prevention of flooding, reduction of greenhouse gases, among many others. This presentation describes a study in Oregon's Willamette River Basin that the US EPA is conducting to develop decision support tools to help communities (1) explore tradeoffs in ecosystem services resulting from alternative decision choices, and (2) quantify community sustainability indicators and their trajectories to balance environmental, economic and social criteria.

Sustainable Sites Initiative (SITES): 2012 Update
Danielle Pieranunzi, Sustainable Sites Initiative
The Sustainable Sites Initiative? or SITES? (www.sustainablesites.org) is an interdisciplinary endeavor to create voluntary national guidelines and a rating system for sustainable land design, construction and maintenance practices for landscapes of all types, with or without buildings. The SITES guidelines aim to restore and enhance our urban "green infrastructure" ? the web of soil and vegetation that manages storm water, cleans and supplies our water and air, conserves energy, recycles organic wastes and creates livable towns and cities. SITES is modeled on the US Green Building Council's LEED? green building rating system. The SITES guidelines and rating system measure performance of a site or landscape, from predesign site assessment all the way thorough design, site preparation, construction, and into operations and maintenance. Presentation will explain SITES credits and the rating system and describe several pilot projects that have gone through the certification process.
SITES Soil Requirements And Credits
David McDonald, Seattle Public Utilities
Soil and organics recycling are the foundation of a sustainable site. The SITES rating system includes: Preserving farmland and environmentally sensitive soils and vegetation; Establishing Vegetation and Soil Protection Zones to limit construction impact; Creating a Soil Management Plan that delineates how soil will be protected or restored; Restoring construction-impacted soil areas by decompacting and restoring organic matter (mature, stable compost is recommended); and Planning for long-term site operations that include organics recycling and reuse. Presentation will discuss the SITES' soil requirements and credits.
Ecosystem Service Benefits of SITES Prerequisites and Credits
Ed MacMullan, ECONorthwest
The SITES prerequisites and credits are designed so that development projects that incorporate these guidelines will protect or enhance the site's water-based ecosystem services, and the values that these services provide. The SITES guidelines will help promote water-based ecosystem services including: groundwater recharge, improved water quality, flow regulation, wetland and riparian habitats and the species that depend in these habitats, and water-based amenities. Presentation will review aspects of how SITES incorporates ecosystem services benefits into the credit and rating system.
Landscapers Or "Bio-Engineers"?
Ron Alexander, R. Alexander Associates, Inc.
With eco-green landscape practices becoming more popular and water management becoming a more critical issue, composters can assist the landscaping industry provide aesthetically appealing projects while meeting the environmental requirements of their clients. ?Paper will outline the changes in the landscape industry and 'compost-based' techniques that composters can teach to their landscape clients.

Wastewater Treatment Plants As Energy, Fertilizer Centers
Protecting Public Health Through Resource Conservation
Sally Brown, University of Washington
Wastewater treatment systems designed to protect public health and the environment have been highly successful in achieving those goals. But as we enter a new era of resource limitations, these systems that were developed to get water clean with no expense spared need to revisit their mission: Resource conservation has to be added to the mandate as part of the way these systems protect public and environmental health. Presentation explores what would it take to transform existing WWTPs not just to energy neutral facilities but to energy "positive" operations.
Oregon Inventory Of WWTP Biogas Production
Thad Roth, Energy Trust Of Oregon
Anaerobic digestion is part of the sewage treatment process at 28 wastewater treatment plants in Oregon. Studies have identified the energy value of the biogas produced and how it is utilized. Learn how Oregon wastewater treatment plants are making beneficial use of biogas today, the projects in place to expand that energy production, and how it will be utilized in the future.
"Cut Through The FOG" Incentives For High Strength Organics
John Holtrop and Matt Criblez, Portland (OR) Bureau of Environmental Services
The City of Portland spends about $100,000 a year cleaning and repairing sewer lines clogged by grease, and about $12 million a year to treat wastewater containing high concentrations of food waste. Wastewater discharges from commercial food service establishments are the main sources of FOG (fats, oil and grease) and other food waste in the city's sewer system. Food service establishments include bakeries, donut shops, hotels, supermarkets, meat processors, commercial kitchens, coffee shops and restaurants. Grease can build up and completely block sewer pipes, creating difficult and expensive maintenance problems for both the city and private property owners.
The city's new Cut Through the FOG reduces FOG and food waste discharges to the sewer system by shifting the costs to the sources of FOG and food waste pollution. On January 1, 2012, the city began?phasing in new rates based on the volume of food waste discharged at each food service establishment. Rates can be reduced by:?Installing and maintaining grease interceptors; Removing food grinders under sinks; Donating or composting other food waste. Technical assistance and information to help Portland food service establishments institute changes is available.
Coming Out Of The Water Closet ? Branding Biosolids
Kate Kurtz, King County (WA) Wastewater Treatment Division
The King County Wastewater Treatment Division recently unveiled its new biosolids brand ? LOOP. Presentation discusses steps and research involved with the branding process, outreach to stakeholders for input, and development of communication tools.
