Geothermal Standards for Connecticut

Intro by Peter Tavino PE, Chairman, Standards Committee

Ground Source Heat Pumps and their associated earth link loop must meet certain standards in Connecticut. While the well drilling code has not yet been enacted, the 2011 Health Department Code is being enforced by Sanitarians, with legal separation requirements as outlined below, including a new separation distances between loop pipe and various septic system components and other piping. The yellow table cell shows CT septic system regulations.

The next table cell in orange shows the proposed well drilling regulations, not yet enacted.

For owners wishing to receive the Connecticut Clean Energy Fund or Connecticut Energy Efficiency Fund rebates, systems must meet with approvals shown in the purple cell.  One cannot get one rebate without getting both.  Therefore the State Historic Preservation Office 30 day review for archaeological and other impacts requires a similar wait for CEEF application and rebate.  And CCEF will not rebate until CEEF approves as shown in purple. Help filling out Prevailing Wage paperwork is available at the link below. CCEF is in the green cell.

The fourth category in green is the Connecticut Clean Energy Fund, currently (March 2011) 14 months into its 28 month long program.

Lastly, the IGSHPA 2010 Standards are discussed in the last red cell of the table below. 

Thank you and good luck adhering to these Standards, Regulations and Suggestions.

 
In force 2011 Septic System Regulation, which Geothermal must meet:
1/1/11
 

Comments: 

In the new code, there are four geo references on page 15, and one each on pages 19, 22 and 23. 

Page 15, Table 1. P. shows 50', 25' and 10' separations. 

The older code used to refer to these three 2007 items below, but the new 2011 code does not.

Some towns such as Greenwich, report that they enforce the three 2007 circular letters and recommendations.

 
4/26/07
 
4/27/07
 
3/5/07  17 page recommendation report
 
 
New code Table 2, 2-C and 2-D does now say "Closed Loop geo exchange bore hole, trench (10' minimum)   - from Sewer Pipe, Tight Pipe or Force Main pipe.
This is an important change although summary of changes does not include it.

Note: the State Health Dept recently ruled that a pump chamber force main that was to cross a horizontal geo trench from the house to the boreholes cannot do that because it would violate Table 2D. The Septic and Pump tanks were thus relocated away from the boreholes and the borehole trench.

 

Per a telephone call and emails made to the Dept. of Public Health, Table 1 P does seem to have a minor error.

50' separation of borehole to septic system is correct, but separation of Trench is not also 50'.

Note that as of 3/10, the State Health Dept will not issue a Circular Memo correcting this mistake.

Efforts are being made to resolve this.

The next line below is correct, saying separate trench and septic, etc. by 10'.

 

 

 

 

Email correspondence posted 5/31/11 of May 21, 2011 emails about 50' separation.

 

 

Draft Well Drilling Regulations (not yet passed.)

http://www.ct.gov/dcp/lib/dcp/pdf/laws_and_regulations/well_drilling_and_geoexchange_regs_-_final_10-20-10.pdf

Comment: so until the Legislature enacts, anything goes for geo as long as old Well Drilling regs are met.

Past comments here:

Chapter V P John Sima, PE presents the proposed CT Geothermal Regulations to the EPA. 03/29/11

www.neiwpcc.org/waterresourceprotection/geothermalworkshop.asp

 

Here are the presentations from that EPA workshop.

www.neiwpcc.org/waterresourceprotection/geothermalworkshop.asp

(Private Comment from Peter Tavino, who was in attendance:

Mr. Hamilton's presentation recommended no propylene glycol,

but to just use water and more borehole instead.

IGSHPA manual says if no PG, minimum Entering Water Temp. = 45 degrees.

A quick calculation shows 3 ton with EWT 30 = 374' borehole needed.

3 ton with EWT 45 = 1474' borehole needed.

 

Mr. Hamilton also said that North Salem, NY school geo had ethyl alcohol antifreeze

leak into water supply and middle schoolers at water fountains were getting sort of inebriated.

At meeting conclusion, EPA and state regulators said this is a reason to regulate.

My nephew works there and we never heard such a thing.

Is this an urban legend, embellished each time it is retold?

I heard the tale occurred in NJ.

Can IGSHPA CT members provide more info?
Thanks,

 Pete)

The Air Conditioning, Heating. and Refrigeration Institute web site is here.

http://www.ahridirectory.org/ahridirectory/pages/wbahp/defaultSearch.aspx

A sample approved AHRI certificate for a water to water unit is shown below.  Heating Capacity is also noted in pencil.

After the system is installed, Efficiency is measured by the installer / S-1 heating contractor.

The (VIP) Verification of Installed Performance excel worksheet is completed

 Hello geothermal contractors thank you for participating in our incentive program. Hopefully you had a good Summer season! At this time the CEEF residential geothermal program continues and is expected to be fully funded for the balance of 2011. We have a revised pre- qualification form for the CEEF program incentive. We have added a space to intake existing site equipment. This is typically information that may be input by the Home Energy Solutions technician. Going forward if you are adding your info. to a geothermal pre- qualification form and the existing system on- site info. is missing, kindly add that information as you are most qualified to know this information, thanks! Here is a copy, the web copy and HES- provided copy will be in place this week.

Connecticut Clean Energy Fund and the State Historic Preservation Office

www.ctcleanenergy.com  has the program description and downloadable forms.

(The final application form requiring submission of a W-9 so that the owner must pay tax is not on the website.) (3/20)

Payment Request Form from 2010 referring to buildings from 1961 might be superseded.

Ask CCEF for their form pending verification that this is the latest:

https://mail.google.com/mail/h/1wnns3z9lfqtj/?view=att&th=12efcdc6e6b5867c&attid=0.3&disp=vah&zw

Recipient of rebate check must supply CCEF and thus the IRS with a completed W-9 taxable income form etc.

(Rebate is deducted from net cost, so 30% tax credit is removed from it for homeowners. $3600 retro rebate on 3 tons  costs $1080 in lost federal tax credit, so bottom line = a $2520 rebate.)

Correspondence regarding the State Historic Preservation Office requiring 30 days to review a site for archaeological and other resources

is on this page.

A new process allowing 40% of the rebate for heat pump only not subject to SHPO delay and outside prevailing wage is under discussion.

Whether 40% is proper and not 60-70% is in discussion. (3/20)

Sample rates for Litchfield County pdf (But no rates for well drillers, pending CCEF Accounting)

 

3/31/11:Message from George Bellas who agreed we could post this message unofficially for the benefit of IGSHPA members:
 

Hi Peter: Please see the attached prevailing wage rate schedule for the Town of Washington effective 7/1/2010. The State changes the rates once a year effective July 1.  As discussed please use Group 5 under operators for the well drilling work for the geothermal projects.

 Also, the following CT Department of Labor website is useful in determining the appropriate prevailing wage rates to use.

 Regards,

-George

6/29/11 CCEF recently ruled that an S-2 heating contractor was unacceptable for rebate.

Instead the system will be installed by an S-1 contractor, to whom the local building dept. issued a heating permit.

Licenses can be checked here:

 

An unofficial one page form requesting to be used to replace the existing 19 page residential and/or 34 page commercial form is attached for IGSHPA chapter member comments to Peter Tavino.  Should the fact that rebate is subject to tax per a future W-9 submittal be made known on the original form?  PDF Here. (3/20)

Comments to the March 2011 CCEF Board meeting about the state of rebates where only 22% has been spent in the first half, etc. made by Peter Tavino not representing the chapter or anyone else are here.

Critics of geo often say "It would not be feasible if there weren't rebates." But they ignore the rebates for fossil fuel burning. From the Wall St Journal survey: Should renewables be funded ? comes these comments:

According to the Environmental Law Institute, U.S. government "Energy Subsidies Favor Fossil Fuels Over Renewables" by a factor of more than 7:1. According to Bloomberg Energy, worldwide fossil fuel subsidies are 12:1 over renewables. 

According to the Environmental Law Institute, fossil fuels in the U.S. get about $72 billion in subsidies, and about 16 billion in subsidies go to renewables, half of which is corn-based ethanol. However, there are other economic costs not accounted for in fossil fuels too, like environmental pollution causing health care costs, military intervention, and depletion of resources, such as U.S. dollars for foreign oil. But why do we subsidize commodities like fossil fuels?

 http://www.eli.org/pdf/Energy_Subsidies_Black_Not_Green.pdf

(See actual figures for 6 years total, slightly different than the comment, but showing huge subsidy and tax break for foreign oil, etc. in competition with geothermal

Fossil fuels = $70.2 billion 2002 to 2008.  All renewables = $12.2 billion leaving a very small percentage for geothermal after wind and solar, etc.)
