SUMMARY Reference Proposal #: C240303A
Agent: Caroline S Lovelace
Property address: 661 N Morgan Street, Estes Park CO 80517
· Where indicated the warranty by RHMM is that the living room and all rooms above the basement will have a radon
concentration of less than 4.0 pCi/L during at least 13 consecutive months after the mitigation, and is expected to stay at that low
level as long as the proposed system is operating and maintained per manufacturer’s information, and radon entry from the
mountain underneath the building entering the building envelope does not dramatically change by independent exterior
conditions.
· After mitigation, short term testing in the living room with two simultaneous devices or a single continuous radon monitor
will be conducted, and is included in this estimate.
· Homes with inaccessible crawl spaces cannot be mitigated with standard Activated Sub Membrane radon mitigation
systems. One of the recognized alternate systems to bring the radon concentration in an existing home down to meet desired
guidelines is a Heating Recovery and Ventilating system (HRV), provided that (1) it is independent of the furnace, (2) operates all
the time, (3) has a balanced system with air flow that is large enough to dilute the radon concentration in the indoor air, and (4)
has an original concentration of radon in the air no higher than a maximum of typically 15 pCi/L. Additional characteristics of such
systems are that they (A) remove radon directly from the air inside the house instead of from the crawl space underneath the
house, and (B) take fresh air in from the exterior and discharge indoor stale air (with the same low radon concentration as is the
indoor air of the house) to the exterior. These exterior intake and discharge have to be at least 10 feet apart from each other on
the outside of the building, and are allowed to be installed above grade level, similar to regular HRV systems that bring fresh air
into the house that are not installed for the purpose of radon mitigation.
ACTIVE INTERIOR RADON MITIGATION SYSTEM USING HEAT RECOVERY VENTILATION SYSTEM ON THE INTERIOR
AIR OF THE HOME.
Material and installation of interior active radon mitigation systems in the form of a Heat Recovery Ventilation (HRV) system that
will be designed to create dilution of the radon concentration in the inside air in the living room and all other rooms of the house
by the method of exchanging the inside air with outside air while recovering energy to bring radon levels below 4.0 pCi/L, under
closed-building conditions in these rooms. It will do so while recovering most of the energy (heat) from the higher energy (heat)
stream through the HRV to the lower energy (heat) stream. In the winter this will keep the conditioned space warmer, and in
summer it will keep the conditioned space cooler compared to direct air exchange.
The HRV-system will be installed in the basement next to the furnace but will operate independent of the furnace in the sense
that the ducts will not be tied in with the furnace ducts. It will have four ducts routed to appropriate locations.
All ducting will be with insulated flexible duct of nominal 6” interior diameter.
Two ducts will be routed from the HRV to the exterior through the basement, and two ducts to the interior of the living room via
the crawl space underneath the house.
The exterior intake of fresh outside air will be through the North side rim joist on the side of the basement door. The exterior
discharge of radon diluted air, which is essentially the indoor air in the house, will be on the other side of the basement door,
provided that exterior intake and discharge are minimally 10 feet apart.
The HRV will have a standard hanging brace screwed into two wooden 2x4’s that will be anchored against the existing south
concrete wall of the basement. The interior supply duct will be routed from the HRV to a floor registers in the Northeast corner of
the living room. The interior discharge of fresh air into the living room will be connected to a floor register in the Northwest corner
of the living room.
The purpose of the duct system is that one combination of ducts will bring the fresh outside air via the HRV into the living room
and the other will take the radon laden air out of the living room via the HRV to the outside.
The designed set-up creates a slightly higher pressure at the interior discharge and a slight vacuum at the interior intake. Proper
balancing of this system to verify flow is established by design through the HRV and is essential for its proper operation.
The principle of operation of this type of system will be different from the more common approach of Active Soil Depressurization
type of radon mitigation systems as it works by diluting the radon in the inside air while reducing the energy loss of the interior,
conditioned space.
The HRV system will need a normal 120 V outlet within 5 feet and is specified to draw less than 2 Amperes of current at the
location where installed. An outlet will be used to power the HRV. Energy costs will be similar to the operation of any electronic
device rated at 240 Watt (2 Amp), due to continuous working of fans in the HRV. In addition, the heat recovery process efficiency
for the air exchange process is specified by the manufacturer during cold weather to be an Adjusted Sensible Efficiency at 32
degrees F of 83%, and at -13 degrees F of 67%.
The HRV device will have the ECO-Touch programmable controller to allow the system to be switched to any of the three
capable operating speeds, and it will have a quiet internal recirculatory defrost cycle that does not depressurize the house during
cold weather conditions (23 degrees F and lower). During this defrost sequence, the supply (exterior intake) blower shuts down
and the exhaust blower continues to ventilate for a pre-set time. The unit then returns to normal operation and continues its HRV
Vent cycle.
The unit has washable electrostatic filters and a counterflow heat exchanger built from a thermoform polymer plates with a
manufacturer limited lifetime warranty, and a standard added MERC-13 HEPA filter. From the HRV manufacturer, a limited
lifetime warranty exists on the counterflow exchanger, 7 years on motors and 5 years on parts.
The estimate for testing and installation work duration is 2.5 working days for testing in our shop and installation on location. The
duct work installation can be started typically within 10 days after this document is signed and received in our office.
A 120 V outlet of appropriate capacity is to be installed within 5 feet of the location of the HRV by a State licensed electrician in
order to plug it in. The placement of the outlet is not included in the total estimate. The HRV device cannot operate more than 30
days from a temporary hook up/extension cord. The State licensed electrician is not included in the Total Estimate.
The HRV is recommended to be installed within the conditioned envelope of the house for its rated efficiency for energy
exchange. If the crawlspace temperature varies too far from conditioned envelope temperatures it is recommended that the area
be closed off from the rest of the crawl space with wood or drywall (not included in the Total Estimate).
A simultaneous two-chamber or Continuous Radon Monitor short term EPA radon test or under closed house conditions inside in
the living room will be performed after completion of installation to determine
the post-mitigation radon level.
The estimated duration for the work is 1 day of preparatory work including hook up and testing of the ECO-Touch controller in
Fort Collins, and 1.5 days work in Estes Park. In addition a two-day radon test in the living room of the house will be conducted
following EPA guidelines.
TOTAL ESTIMATED HRV-RADON REDUCTION
INSTALLED, INCLUDING POST-MITIGATION RADON TEST $ 4,052.-
----------
TOTAL ESTIMATE: $ 4,052.-
EXCLUSIONS:
A)Outlet to be installed by a local licensed electrician consistent with electrical Code requirements.
B)If the seasonal variations of the temperature of crawl space are not appropriate for installation of an HRV (which is
recommended to be located within the conditioned envelope of the house) an insulated box needs to be constructed around the
HRV with a vent connection to the air in the finished basement to create conditions around the HRV consistent with the
conditioned envelope of the house inside the box. If not, large temperature variations of the HRV can affect the energy
conversion efficiency.

Dear Contractor:
At the time you apply for a building permit, you are required to pay a use tax deposit. The tax deposit is
determined assuming that 50% of the valuation will be comprised of construction materials. That amount is then
multiplied by the County tax rate of .8% to calculate the deposit. The tax you pay when the permit is issued is
merely a deposit.
Since the tax deposit is based on a material/labor ratio, it is important that actual costs be monitored and
compared with the tax deposit. At the end of your project, a Project Cost Report (PCR) must be completed to
compare the deposit to the tax due based on actual material costs. The outcome of the PCR may be that
additional taxes may be due, or a refund could be issued.
To calculate the actual material costs, all material invoices are added to the materials from the subcontractors’
invoices. It is preferred that actual material costs from the subcontractor be used when known, if not, fifty
percent (50%) of the subcontractor’s invoice will be used if a breakdown of materials and labor can not be
provided. If labor cost account for more than fifty percent (50%) of the subcontractor’s invoice, please provide a
copy of the invoice or a subcontractor affidavit for back-up documentation. If claiming additional sales tax paid,
a copy of the receipt must be provided.
Please note: Larimer County sales tax is not due on the purchase of construction and building materials at the
time of sale IF the purchaser presents a building permit showing that the County use tax has already been paid.
For your convenience, a PCR is attached to your building permit. When submitting the completed PCR, a copy
of the building permit, a final cost summary, copies of subcontractors’ invoices, copies of material receipts, and
any other back-up documentation to help support your claim should be included. The completed packet with
applicable payment is due within 60 days from the issuance of the Certificate of Occupancy, Letter of
Completion, finalization of project or at the expiration of the building permit. All PCRs submitted after the 60
days are subject to penalty and interest.
There is a possibility that the sales and use tax rate will change during the construction of your project. To
ensure we use the correct sales/use tax rates, dates of the purchases must be provided. The easiest way this can
be done is to provide copies of all your receipts. Or you can have the purchases individually listed out on your
job cost worksheet. If dates of the purchases are not documented, the sales and use tax rate when the building
permit was issued will be used to determine the taxability of the material used in your project.
If the building permit expires, a project cost report must be submitted on the work that was completed.
If you have any questions concerning project cost reporting requirements or need additional forms, please
contact the Finance and Sales Tax Office at (970) 498-5930. Thank you in advance for your cooperation.

the Larimer County Finance Division. No additional documentation is required.
Calculation Section (bottom box)
Line 1 – Enter taxes paid, include the total Larimer County sales/use tax paid on the building permit(s) and
any additional County tax paid on construction or building materials. Please include copies of both the
building permit and any invoices or other forms of proof of sales or use tax payment.
Credit for additional County sales tax will only be given if copies of receipts are provided.
Line 2 – Enter actual material costs from the job cost summary and multiply by 0.8% to calculate the use tax
that should have been paid.
To determine actual material costs, take 100% of materials purchased for the project and 50% of sub-
contractor invoices if a breakdown of materials and labor can not be provided. (It is preferred that actual
materials costs from the subcontractor are used if known. If labor accounts for more that 50% of the
subcontractor’s invoice, provide a copy of the invoice or a subcontractor affidavit for back-up
documentation.) Additionally, if items such as driveways, sidewalks, parking lots and landscaping are
included in the project contract, the material costs should also be included in your actual material cost.
Line 3 – If Line 2 is greater that Line 1, additional tax is due to Larimer County. Please submit a check for
