Water Quality Trading Program Feasibility Study Amendment
Scope of Work for City of Meridian, Idaho
May 11, 2015
Introduction: The Freshwater Trust has completed an initial water quality trading feasibility study
for the Wastewater Treatment Facility(WWTF)for the City of Meridian, Idaho which will face strict
new limits in its upcoming NPDES permit. In order to maximize the utility of the analysis for City
planners, The Freshwater Trust (The Trust)will first refresh initial estimates of potential future
loading and nutrient credit demand through consultation with WWTF operators and data review.The
Freshwater Trust will then provide a final deliverable summarizing Tasks 1-4 of the draft feasibility
study with the most current data. These tasks were previously completed over a period of several
months; decisions made for final tasks will be incorporated into earlier analyses and a cohesive final
report will provide an overview.
Background:Approximately 70% of nutrient loading into Five Mile Creek is from nonpoint sources;
the Meridian WWTF is responsible for reducing the amount of phosphorus in the treated wastewater
it releases, which ultimately drains to the Boise River. The City is expected to receive a new
phosphorus limit in 2015 via the Boise River Phosphorus TMDL; the limit is currently a component of
the target assigned to the Boise River by the Idaho DEQ's Snake River-Hells Canyon TMDL.
The City has already invested in an upgraded WWTF. As the population grows, the city will seek to
address increased loading and lower nutrient limits with a more cost-effective solution. To this end,
the City is interested in assessing how a water quality trading program could fit into its overall facility
compliance plan. The following two tasks will complete the water quality trading program feasibility
study.
Task 1) Consultation, Data Review, and Refreshed calculations
May 25, 2605 — June 26, 2015
- The Trust will review the City's past discharge monitoring reports(DMR)with Meridian
WWTF operators to determine the data that is most reflective of current nutrient
concentrations and flow.
-* DMR data most reflective of current operations will be used to revise estimates of current
phosphorus loading and make future projections based on population growth with Meridian
WWTF operators.
-* The Trust will consult with Meridian WWTF plant operators and engineers to determine the
range of wasteload allocations and phosphorus load reductions through technology
upgrades that are most useful for facility planning purposes.
2
Potential future loading scenarios will be revised based on updated values for wasteload
allocations and selected phosphorus concentration scenarios.
-* Coarse cost estimates will be refreshed based on the results of phosphorus loading
scenarios.
—� Deliverables:
(a) The Trust will provide revised results for potential future phosphorus loading
scenarios and the associated phosphorus credit demand for water quality trading.
(b) Revised estimates will be provided in tabular format and included in the final
report.
Estimated Cost: $4,240
Task 2) Summary Report
¢ ?CoRitiit
The Trust will consolidate four previous memos summarizing potential future loading, supply
analysis, policy considerations, and trading plan elements into one final report. Refreshed
results based on the results of Task 1 will be incorporated into the final report. Any new policy
developments during this time period will also be incorporated.
—> The Trust will review analysis of phosphorus loading in neighboring watersheds (completed
through a separate contract supporting development of the Lower Boise River Trading
Framework)to evaluate the potential range of credit values and cost per credit for the City. If
the City expands its service area outside of the Fifteenmile Creek watershed, it will expand its
potential phosphorus credit supply and increase the feasibility of implementation. The City's
potential to do so, and the potential benefits of doing so, will be included in the summary
report.
Deliverables:
(a) The Trust will provide a final report summarizing nutrient trading feasibility and
considerations for the City of Meridian.
(b) The Trust will present refreshed results to the City of Meridian in person at a date
that is convenient to both parties.
Estimated Cost:$4,450
Assumptions:
• The City will be available for two conference calls to work through the DMR data and
treatment technology scenarios.
• The City and its engineers participate in meetings with The Trust.

Suggested Meetings:
• The exact meeting schedule will be determined after contracting, but The Trust proposes a
brief kick-off meeting via conference call with the City and its consultant(s)at the beginning
of this Scope of Work.
• As needed, The Trust will hold regular conference calls with the City and its consultant(s).
• The Trust proposes a concluding presentation of the deliverables developed through this
Scope of Work in July 2015.This in-person meeting will focus on answering any questions
and developing next steps.
Conclusion:
The Trust has proposed the Scope of Work to support the feasibility analysis completed in spring of
2015, and to respond to additional questions from the City and its engineers.
Total Estimated Analysis Cost(5/25/15 through 7/31/15):$8,690
