SUBJECT:
A RESOLUTION APPROVING AN AGREEMENT IN AN AMOUNT NOT TO
EXCEED $73,740 BETWEEN THE CITY OF PUEBLO AND OTTERTAIL
ENVIRONMENTAL, INC., FOR PROFESSIONAL SERVICES ASSOCIATED
WITH ENVIRONMENTAL MONITORING
SUMMARY:
Attached is a Resolution accepting an agreement between the City and OtterTail Environmental,
Inc for professional services associated with environmental monitoring. The monitoring
performed will include a Multi-Metric Index Study in selected portions of the Arkansas River
watershed, and related observations of the habitat and sediment.
PREVIOUS COUNCIL ACTION
:
On August 26, 2013, the City Council approved Resolution No. 12759, authorizing OtterTail
Environmental to perform the 2013 Multi-Metric Index Study.
BACKGROUND
:
The Colorado Department of Public Health and Environment (CDPHE) recently changed the
regulations that establish aquatic life classifications for water bodies and implemented guidance
for methods to assess use attainment for aquatic life uses through a Multi-Metric Assessment.
The new rule changed the method used to evaluate whether aquatic life uses are attained in
surface waters, and CDPHE is currently proposing to use this method in determining
compliance with the narrative standard for nutrients. A finding of non-attainment will result in
the stream segment being added to the list of impaired waters, which in turn will affect the
effluent limits applied to Pueblo’s Water Reclamation Facility. The next evaluation will be
performed in 2016. It is in the interest of the City of Pueblo to perform assessments to
determine the compliance status of Segment 1a of the Lower Arkansas River, and to ensure
that the assessment will not be based on the result of a single sampling effort.
FINANCIAL IMPLICATIONS
:
Funds for the 2014 Multi-Metric Assessment study are available from the Sewer User Fund and
were appropriated in the 2014 budget.
BOARD/COMMISSION RECOMMENDATION
:
Not applicable
STAKEHOLDER PROCESS
:
Not applicable
ALTERNATIVES
:
The alternative is to wait for CDPHE to determine if the stream is meeting the narrative nutrient
standard based on one sample collected by the CDPHE staff. Impairment listing will be based
on that single sample rather than yearly samples that show a more complete perspective of the
river water quality. The potential of listing the stream as impaired is significantly increased
when good baseline data is not available.
RECOMMENDATION
:
Approval of the Resolution.

Agreement for Professional Services between the City of Pueblo and OtterTail Engineering, Inc.
AGREEMENT FOR SERVICES
THIS AGREEMENT is made and entered this 26th day of August , 2014, by and between the

EXHIBIT 1
Scope of Work for the
Pueblo Wastewater Department's Multi-Metric Index Study:
2014 Field Season
This Scope of Work (Scope) describes tasks associated with the 2014 field season to be performed by
OtterTail Environmental, Inc. (OtterTail) in continuing an examination of Colorado's Multi-Metric Index
(MME) or Tolerance Indicator Value(TV[), periphyton chlorophyll a, and physical habitat on behalf of the
City of Pueblo Department of Wastewater (Wastewater). The study area is in the vicinity of wastewater
discharge from the James R. DiLorio Water Reclamation Facility (WRF) into the lower Arkansas River,
Segment la. Because it is possible that TVI will replace MMI as the eventual evaluation metric, we will
implement analysis of the data using either of the metrics, but for the purposes of this scope of work, will
use the acronym MMI since which is still not determined. The scope of work will remain the same no
matter which metric is used.
The objective of the 2014 study is to supplement data provided to Wastewater from our 2011, 2012 and
2013 sampling, complete further analysis of macroinvertebrate diversity and community composition, and
compare data between sample years. Additional information on specific approaches proposed for this study
has been described in greater detail in previous reports.
Task 1 Sampling Planning and Preparation
As Colorado's MMI is currently intended to serve as the primary indicator of aquatic life use attainment or
impairment of a waterbody by the Colorado Department of Public Health and Environment(CDPHE), it
will also be used in this study as an indicator of aquatic life health.
Task 2 Methods
Task 2.1 Macroinvertebrate Sampling
OtterTail will collect three replicate macroinvertebrate samples from each of the three established sampling
reaches using the CDPHE "soft-bottomed" methodology (sampling from vegetated bank margins,
submerged woody debris or snags, and aquatic macrophytes) during late-summer/fall within the Index
Period (May 1-October I). OtterTail will sort and identify macroinvertebrates to the level of Operational
Taxonomic Unit(OTU)as defined by CDPHE Policy 10-1.
Task 2.2 Habitat Sampling
OtterTail will complete quantitative physical habitat mapping within three sample reaches. This effort will
include an assessment of bed and channel stability, identification of potential sedimentation and sediment
transport issues, and quantifying physical habitat according to available fish/macroinvertebrate habitat
types (e.g., riffles, runs, pools, snags/woody debris, undercut banks, and submerged vegetation). Modified
Wolman Pebble Counts will be completed within each sample reach following the prior study
specifications. Additional physical habitat and pebble count assessments will address specific needs to
identify potential macroinvertebrate stressors. Additional habitat sampling is necessary to focus on
.0tteel'ail 2
Environmental[ August 2014
potentially important habitat parameters, identify potential data gaps, and establish the natural range of
conditions in the Arkansas River.
Task 2.3 Periphyton Chlorophyll-a Sampling and Analysis
Collection of periphyton for calculation of chlorophyll a will be conducted concurrent with
macroinvertebrate sampling. The methodology will follow the CDPHE's recommended procedures that
were implemented during OtterTail's previous sampling efforts.
Task 3 Analysis and Reporting
OtterTail will calculate MMI scores using Colorado's Plains/Xeric Biotype metrics for all
macroinvertebrates samples collected and for available macroinvertebrate data that were collected prior to
this study. MMI scores will be compared statistically to determine potential differences between sites, river
banks, and sample years (2011-2013). OtterTail will also complete a statistical comparison of physical
habitat mapped between sample reaches,as appropriate.
OtterTail will continue to preliminarily identify potential macroinvertebrate stressors in the study area by
examining habitat, water quality, and other potentially pertinent data (as available) compared to MMI.
Potential stressors examined for the Arkansas River, Segment la, will include physical habitat
measurements, water quality data (collected by Wastewater), pebble counts, urbanization, and others. The
ongoing stressor identification process is anticipated to detect the most likely stressors as well as additional
information that may strengthen future analyses.
A detailed summary of the results of 2014 sampling, analyses, and comparison of sample years will be
provided to Wastewater in a written report. Raw data, statistical summaries, and analyses will be provided
with the report.

Schedule
OtterTail proposes to conduct the sampling during the last two weeks in September, 2014 if
stream flows allow. If flows do not allow collection during this preferred time frame, OtterTail is
prepared to conduct the surveys in October as soon as accessible. A draft of the report results
will be provided no later than February, 28th, 2015. A final report will be provided no later than 2
weeks after receipt of comments.
