TITLE
A RESOLUTION AWARDING A CONTRACT IN THE MAXIMUM AMOUNT OF
$63,602.00 TO GEI CONSULTANTS, INC. /CHADWICK ECOLOGICAL
DIVISION, FOR TESTIMONY AND EXPERT WITNESS SERVICES
ISSUE
Should the City Council award a contract to GEI Consultants, Inc. /Chadwick
Ecological Division, for testimony and expert witness services?
RECOMMENDATION
Approval of this Resolution
BACKGROUND
The consultant will provide written and oral expert witness testimony as to the
occurrence of selenium and sulfate in the Lower Arkansas River, the degree to
which aquatic communities are affected by selenium, and site - specific criteria for
selenium that would provide appropriate protection for aquatic species.
In 2004 the Colorado Water Quality Control Commission placed Segment 1a of
the Lower Arkansas River (Fountain Creek to Avondale) on the list of threatened
or impaired waters because selenium concentrations exceed the State - assigned
water quality standards. Pueblo's James R. Dilorio Water Reclamation Facility
discharges to this segment. The effluent limits and other conditions contained in
the discharge permit under which the Water Reclamation Facility operates are
directly affected by beneficial use classifications and standards applied to the
segment, thus affecting the operating costs for the facility.
The consequence of the river segment being placed on the impaired stream list
is that federal law requires that a Total Maximum Daily Load (TMDL) and a
Waste Load Allocation (WLA) be performed. Strict application of these
processes could result in Pueblo being ordered to remove selenium from its
reclaimed water. The cost of selenium removal using reverse osmosis treatment
technology was estimated at $35 million in construction costs and $2 million
annual operating costs in 2000 dollars. Because Pueblo contributes less than 5
percent by mass of the selenium in the river segment, Pueblo's removing
selenium from its effluent would not bring the river segment into compliance.
Selenium and sulfate exceed Colorado's water quality standards in the Lower
Arkansas River, largely as a result of natural sources. In 2004, the Wastewater
Department undertook additional studies to identify and quantify sources of
selenium and sulfate in the Arkansas River from the Pueblo Dam to the Huerfano
River near Boone. The Colorado Department of Health and Environment and
EPA Region 8 have tentatively agreed that the study meets the requirements for
a Use Attainability Analysis, which is a mechanism allowed under the Federal
Clean Water Act to justify less restrictive water quality standards. The Colorado
Department of Health and Environment has scheduled a public hearing to review
water quality classifications and standard for the Arkansas River Basin in June
2007. The City of Pueblo intends to recommend site - specific standards for
selenium and sulfate.
GEI Consultants, Inc. /Chadwick Ecological Division was part of the study team
that analyzed and interpreted data from the 2004 study. GEI Consultants,
Inc. /Chadwick has also performed considerable research on agricultural irrigation
practices in the Lower Arkansas River Basin and is recognized as an authority on
irrigation - related water quality issues by both the Colorado Department of Health
and Environment and by EPA Region 8. Their testimony will be needed in
having appropriate water quality standards adopted.
FINANCIAL IMPACT
Funds for this project are available from the Sewer User Fund and were
appropriated in the 2007 budget.
