ITEM FOR WORK SESSION:
Richfield Ice Arena Refrigeration Project Information and Staff Recommendations
EXECUTIVE SUMMARY:
The City Council work session will focus on the Richfield Ice Arena Refrigeration Project including:
• The history of the facility and it's connection to the community.
• An understanding of the community groups that utilize the facility and the impacts this project may
potentially have on them.
• Project need and associated costs.
• Project timeline and ne)d steps.
• Staff recommendations to consider for an October 22 Council vote to decide what option to pursue with
the project.
Staff's recommendations are:
• Complete the refrigeration project in 2020, signing quotes in November 2019 for the work to be done
and to secure pricing.
• Plan community engagement efforts in August, September, and early October.
• Bring engagement responses back to the council for a final vote on the project on October 22.
• Fund both sheets of ice and building improvements that would allow for year-round ice and/or dry floor
activities.
• Fund the project with a combination of sources including: golf course sale monies, budgeted capital
monies, grants, and contributions from partner organizations.
• No longer use harmful R-22 refrigerant.
• See significant annual energy savings.
DIRECTION NEEDED:
Please review the attachments and either prepare comments/questions for discussion at the work
session or send comments/questions to Amy Markle, Recreation Services Director, prior to the
meeting by email at amarkle@richfieldmn.gov and they will be addressed at the work session.
BACKGROUND INFORMATION:
A. HISTORICAL CONTEXT
The Richfield Ice Arena was built in 1971. A second sheet of ice was added in 1999. The current
equipment that both sheets of ice run-on are original. Both ice rinks have direct R-22 refrigeration
system. R-22 is a chemical that is no longer being produced after the end of 2019. The price of e)asting
R-22 is anticipated to increase sharply, and become obsolete over time. This problem is not unique to the
Richfield Ice Arena, almost every arena in the state is facing the same issue.
B. POLICIES (resolutions, ordinances, regulations, statutes, etch
The Environmental Protection Agency has mandated that all production of ozone -depleting HCFC-22 (R-
22), stop December 31, 2019. Please see attachment.
C. CRITICAL TIMING ISSUES:
The following issues create a sense of urgency for the project:
• The cost of replacing one ice sheet vs. two: the second sheet adds appro)amately $700,000
varying with annual construction labor wages.
• The cost of total project materials escalates every year by a minimum of 4%.
• The elimination of R-22 production will put the cost at the demand of the market.
• Every year we are losing/leaking R-22 and have to add roughly 500 Ibs to keep our system
operating efficiently.
• We are already seeing mechanical failures of pieces of equipment.
• Our prime location we continue to be in high demand for our ice time and facility.
• Timing of this project will be competitively bid by many arena contractors.
D. FINANCIAL IMPACT:
The current quote we have for the project costs are estimated at:
• 2020 construction- $3.4M + $400,000 building improvement costs (HVAC system, roof, and
indoor turf)
• 2021 construction- $3.5M + improvement costs
• 2022 construction- $3.6M + improvement costs
• The project can be funded in a variety of ways including: capital funds that were already budgeted
($430,000), golf course sale monies, grants, and organizational partnerships
E. LEGAL CONSIDERATION:
N/A
ALTERNATIVE(S):
The following are alternatives to staff's recommendations:
• Replace one refrigeration plant now and defer the second ice sheet to a future time.
• We run on the current system and incur financial, community, and environmental risks.

1.1
What Is the HCFC Phaseout?
Under the U.S. Clean Air Act and the Montreal
Protocol on Substances that Deplete the Ozone
Layer, the United States is phasing out the production
and import of hydrochlorofluorocarbons (HCFCs)
in order to protect the stratospheric ozone layer.
By phasing out the production of ozone -depleting
substances (ODS) like HCFCs, we are reducing the risk
of skin cancer caused by exposure to UV radiation. In
addition, many of these ozone -depleting substances,
as well as their substitutes, are greenhouse gases that
contribute to climate change.
No Immediate Change Is Required
HCFC-22 is used as a refrigerant in many applications,
including ice rinks. Starting on January 1, 2020, U.S.
production and import of HCFC-22 will end. This does
not mean that use of HCFC-22 must stop at that
time. Since a significant inventory of virgin HCFC-22
exists, and recovered and reclaimed material will be
available, the U.S. Environmental Protection Agency
(EPA) expects use of HCFC-22 to continue well into
the future.
Planning for the Future Is Important
Even though there is no immediate need for change,
supply of HCFC-22 will decline over the next few years,
and prices may rise. For existing HCFC-22 systems,
this makes tightening leaks and performing preventive
maintenance even more important to keep refrigerant
emissions down and reduce the need to purchase
additional HCFC-22. When the time does come to
replace or retrofit an existing system, there are many
alternatives available that are safer for the environment.
EPA has listed several examples of alternatives in the
table on the next page.
What Alternatives Can Be Used
Instead of HCFC-22?
Many alternatives that are safer for the
environment than HCFC-22 are available for
use both in new rinks and in existing systems
that require retrofit. See the table on the next
page for a list of some acceptable non -ozone -
depleting alternatives under EPA's Significant
New Alternatives Policy (SNAP) Program.
Some of these alternatives are listed for use
in retrofitted HCFC-22 systems, and others
are only listed for new ice rink refrigeration
systems. A full list of acceptable alternatives
under SNAP is available at www.epa.gov/
ozone/snap/refrig erants/lists/icerinks. html.

GWP = Global Warming Potential. GWP is a measure of how much a given mass of greenhouse gas is estimated
to contribute to global warming relative to the same mass of carbon dioxide.
When considering an alternative for retrofitting a system, be sure to follow the manufacturer's suggested
handling and installation guidelines and to consider possible effects on the system's energy consumption.
Are There Other Refrigerant Regulations Affecting Ice Rinks?
Ice rinks are subject to refrigerant management regulations under section 608 of the Clean Air Act, specifically
the requirement to keep leak rates below 15% for comfort cooling appliances and below 35% for refrigeration
equipment. In addition, it is illegal to knowingly vent refrigerant —both ozone -depleting refrigerants and the
alternatives' —during servicing, maintaining or disposing of a refrigeration or air conditioning system.

'Several alternatives have been exempted from the venting prohibition. Examples include ammonia in commercial or industrial process refrigeration
or in absorption units, and carbon dioxide, nitrogen or water in any application. A complete list is available in the U.S. Code of Federal Regulations at
