From Sam Hadeed, shadeed@wef.org. NBP EMS 101 Workshop Summary Report.
A summary of the NBP environmental management system (EMS) 101 training
workshop that was held on January 20-21, 2004 is available for viewing. The workshop
covered EMS basics, the NBP EMS framework (the 17 Elements), how to get started,
and instruction on how to develop an EMS that supports the four performance
improvement “outcomes” (quality management practices, public participation, regulatory
compliance, environmental performance). The workshop was intended for agencies
that are just getting started with their EMS effort. The summary also includes an excel
spreadsheet containing the workshop attendees and a photo album with many of the
program participants. To view the workshop summary, visit the NBP web page:

From Ash Sajjad, sajjad.ash@epa.gov. WEF Innovative Uses of Biosolids and
Animal Manure Symposium. The fifth symposium on "Innovative Uses of Biosolids
and Animal Manure," June 30-July 2, 2004, in Chicago, IL will focus on the innovative
uses of animal manure and biosolids, government mandates that support innovative
technology, the new or significantly improved technologies as related to innovative and
value-added products, the role of entrepreneurs in the implementation and application
of innovative technologies, and marketing aspects of innovative technologies. The
Symposium is designed to bring together professionals for the exchange of information
and ideas. Interested agricultural and municipal solids management professionals; utility
managers; natural resource, energy, transportation and environmental professionals;
members of the research community; technical service providers; policymakers; and
technology providers are encouraged to attend. Emphasis will be placed on
presentations related to recycling and value-added opportunities that reflect innovative
management, technology or systems approaches. To register, visit:

From Chlorine Chemistry Council’s Executive Newsline, 3-19-04. EPA Finds High
DBP Levels from Alternative Disinfectants. A new study from the Environmental
Protection Agency (EPA) shows that the use of "alternatives" to chlorine may increase
levels of toxic byproducts in drinking water. EPA researchers sampled drinking water
across the U.S. from systems using various disinfection methods and with different
water quality. The study, The Occurrence of Disinfection By-Products (DBPs) of
Health Concern in Drinking Water, quantified levels of about 50 DBPs, considered
"high priority" for potential adverse health effects. Researchers found that the use of
alternative disinfectants, such as chloramines and ozone, lowered levels of regulated
DBPs, but actually formed higher levels of unregulated and potentially more toxic
byproducts. In addition, EPA detected more than 200 previously unidentified DBPs.
Following the study's release, Inside EPA reports that drinking water utilities may be
even more reluctant to switch disinfectants without first learning all of the downfalls of
replacement treatments. Contact CCC’s Jeff Sloan, 703-741-5183.

From WEF National Office. WEF 2004 Washington Briefing. The Water Environment
Federation’s 2004 Washington Briefing, scheduled for April 26-27, 2004 at the
Renaissance Hotel in Washington, DC, is designed to provide attendees with
information on key regulatory and legislative activities at the federal level. Featured
topics include EPA’s proposed blending policy, watershed issues, including water
quality trading, monitoring, and watershed permitting, and enforcement and
environmental results. During the morning keynote, Ben Grumbles, Acting Assistant
EPA Administrator for Water, will update attendees on the agency’s key initiatives and
any shift in priorities under a new administrator. Speakers will discuss wet weather
treatment options for publicly owned treatment works, provide perspectives from both
sides of the blending policy debate, share information on public health risks, and give
first-hand accounts of how blending is being practiced today. The afternoon line-up
features speakers on watershed issues, including water quality trading, monitoring, and
watershed permitting. The first day will end with an innovative panel discussion on
enforcement and environmental results, which will include speakers from EPA's Office
of Enforcement and Compliance Assurance and the U.S Department of Justice. To

From AMSA National Office. AMSA 2004 National Environmental Policy Forum &
34th Annual Meeting. AMSA’s 2004 National Environmental Policy Forum & 34th
Annual Meeting will be held from May 22-26, 2004 at the Renaissance Washington DC
Hotel. This year’s theme, Politics, Policy & POTWs, will focus on the regulatory and
legislative priorities of the nation’s publicly owned treatment works (POTWs) and will
honor the outstanding achievements of the clean water community over the past year
through AMSA’s National Environmental Achievement and Peak Performance awards.

From Lori Mathes, lmathes@wef.org. WEF-A&WMA 2004 Odors & Air Emissions
Specialty Conference. The Water Environment Federation (WEF) and the Air & Waste
Management Association (A&WMA) are cosponsoring the international specialty
conference Odors and Air Emissions 2004, in cooperation with the Pacific Northwest
Clean Water Association. The conference will be held at the Meydenbauer Center in
Bellevue, WA from April 18-21, 2004. Every two years, this conference brings together
environmental professionals from around the world for a showcase on odors and air
emissions management. Online registration closes on March 31st. To view the

                        Greeley, Colorado
                        Water Pollution Control Facility
                        Dennis Schump              schumpd@ci.greeley.co.us

            The City of Greeley is located in northeastern Colorado approximately 50
            miles from Denver, 50 miles from Estes Park, and 50 miles from Cheyenne,
            Wyoming. Greeley is a very fast growing community with a population of
            83,130. The Water Pollution Control Facility (WPCF) is designed to treat
            14.7 MGD; the influent flow in 2003 was 7.9 MGD. The WPCF has been in
            operation since the 1930’s with the last major Administration building
            renovation completed in 1996.

Greeley is situated in a highly productive agricultural area, and receives less than 15
inches of moisture per year. The area around the City is dependent on irrigation for
crop production. Winter wheat is grown near Greeley (less than 10 miles), where

irrigation is not available. All of the biosolids produced is sent to winter wheat areas for
land application.
metric tons in 2003.
The Water Pollution Control Facility, an advanced secondary wastewater treatment
facility, pumps primary clarifier sludge at 4.5%TS directly to the primary digester. A
Sharples thickening centrifuge thickens waste activated sludge to about 6%TS and it is
also pumped to the primary digester. The WPCF has two (2), 850,000-gallon primary
digesters that are operated in series and one 850,000-gallon emergency storage tank.
Ferric chloride can be added to condition the biosolids when needed. After digestion,
the Class B biosolids are sent to an Alfa Laval DS 706 dewatering centrifuge. The
centrifuge cake averages 20%TS. The cake is discharged into a Schwing high solids
pump, and then it is pumped to an overhead live bottom hopper in a truck loading area.
A private contractor performs the trucking and land application services. The City
produced 1300 dry metric tons in 2003.

Future WPCF goals include EMS certification, dewatering centrate flow equalization
(April 2004), UV disinfection (2005), and implementing a process that converts excess
biogas to natural gas, with the subsequent sale of the natural gas that will produce a
royalty income stream at no cost to the City (2005).
