Any product not containing the letters “USP” will not be acceptable for this use, unless vendor documentation is produced to demonstrate equivalency.
Geothermal system – a sealed, watertight loop of pipe buried outside of a building foundation, which is intended to recirculate a liquid solution through a heat exchanger. This includes but is not limited to vertical loop, horizontal loop and body of water loop systems.
Geothermal system contractor – any individual who installs geothermal systems except a geothermal system excavator.
Geothermal system excavator – any individual who excavates for the purpose of installing a geothermal system. This includes but is not limited to drilling, boring, jetting, or digging.

(A) The application shall be accompanied by a plan showing the location of all existing structures, wells, septic tanks, secondary sewage treatment units, cesspools, privies, sewers, lakes, ponds, or streams on the applicant’s property and on neighboring properties, if they are within 200 feet of the proposed geothermal system(s).
(B) Prior to the approval of the inspection application, the Board of Health, at its discretion, may require additional information, and/or inspect the property and neighboring properties.
6 TCC 9-6 INSPECTION FEE
Each application for the inspection of a geothermal system shall be accompanied by a fee of $100.00 payable to the Tazewell County Health Department. This fee shall not be refundable in the event that an individual decides not to construct or modify the geothermal system.
6 TCC 9-7 REGISTRATION OF GEOTHERMAL SYSTEM CONTRACTORS AND EXCAVATORS
All individuals who install or excavate geothermal systems in Tazewell County shall be registered annually with the Board of Health. A registration fee of $50.00 shall accompany the registration application. The registration shall expire on December 31st of the year of issue. The registration requirement shall not apply to water well drillers licensed under the Illinois Department of Public Health Water Well and Pump Installation Contractor’s License Code. The registration requirement shall not apply to an individual who drills or excavates a geothermal system on land which is owned or leased by him and is used by him for farming purposes or as his place of abode.
6 TCC 9-8 INSPECTIONS
The Tazewell County Health Department shall be notified by telephone or in writing at least 24 hours prior to the drilling of a vertical geothermal system or excavating a horizontal geothermal system. Information to be provided to the Tazewell County Health Department includes: date drilling/excavating completed, name of well driller/excavator, depth and diameter of drilled holes, if applicable and number of 50 pound bags of bentonite grout used, if applicable. In the case of a vertical geothermal system, the inspector shall measure the location of each hole in the geothermal system relative to one or more physical features, such as corners of a house. In the case of a vertical geothermal system, the drilling and grouting of the holes should be witnessed (audited) by a representative of the Tazewell County Health Department for each contractor annually.
6 TCC 9-9 USE OF FOOD GRADE PROPYLENE GLYCOL AS COOLANT
