GEORGIA AMENDMENT TO THE 1994 STANDARD PLUMBING CODE
*Amend Section 507.8.4 of the 1994 Standard Plumbing Code to read as follows:
507.8.4 The discharge from the relief valve shall be piped full size separately to the outside of the building or to an indirect waste receptor so that any discharge can cause no personal injury or property damage and can be readily observed by the building occupants. In no case shall the discharge from a relief valve be trapped.
EXCEPTION: In basements or one and two family dwellings, the discharge from the relief valve may be piped upward when necessary. A thermal expansion control devise shall be installed in accordance with Section 613.2.1. An elbow shall be placed to the valve outlet and provisions shall be made at the low point for positive drainage.
*Said Plumbing Code is further amended by deleting in its entirety section 613.2 Thermal Expansion Control, and substituting the following in lieu thereof:
613.2 Thermal Expansion Control
If water is heated and stored in a consumer's system and the system has been closed by the installation of a backflow preventor or a pressure reducing valve, a thermal expansion control device shall be installed at an accessible location and in accordance with manufacturer's installation instruction. The device shall limit thermal expansion of the water being heated to not more than 80 pounds per square inch (552 kPa) static pressure at any fixture on the system. A potable water expansion tank or auxiliary relief valve set at 80 PSI (552 kPa) shall be acceptable.
The auxiliary relief valve shall be in addition to the eater heater safety relief valve. This thermal expansion control device shall be designed and trimmed for repeated operation. The valve shall have a minimum one-half inch pipe size. It shall be installed in accordance with manufacturer's installation instructions.
GEORGIA AMENDMENT TO THE 1995 CABO MODEL ENERGY CODE WITH GEORGIA SUPPLEMENTS AND AMENDMENTS
*Add the following footnote to Table 502.2 1a of the 1995 CABO Model Energy Code, to be designed as footnote 5 and renumber the remaining footnotes:
" 5. Slab edge insulation is not required for unheated slabs in areas of very heavy termite infestation probability as shown in Figure 4 contained in Chapter 8."
* The 1995 CABO Model Energy Code with Georgia Supplements and Amendments is further amended by deleting in their entirety the table concerning 3500 Heating Degree Days and 4500 Heating Degree Days in Chapter 6 of the Georgia Supplements and Amendments and substituting in lieu thereof the following:

1. Your building shall be a one or two family detached dwelling
2. Your building shall not be larger in size than 5,000 square feat of conditioned floor space
3. Your building site must be located in an area of the state where climatic conditions shown in Chapter 3 of The Energy Code are 3500 Heating Degree Days (HDD) or less
4. Your building is three stories or less in height
5. You shall not make any substitutions of any kind for R-values listed below
6. Your window and door openings shall not exceed 19.0% of the gross (conditioned space) wall area
7. You shall comply with the Energy Code requirements for limiting air infiltration
8. Equipment efficiencies required by the Energy Code shall be observed

All R-values shall be printed on the actual insulation and be stabilized R-values
These R-values may result in some degree of "over-design". This was done so this method could apply to almost all one and two family residential construction built in Georgia (except mountains). If you must change one or more of the R-values listed to a lower R-value, then do not use this method. No substitutions are allowed here.
Instead, you may use one of the other methods to show compliance, such as the Climate Zone Table or Tradeoff Worksheet. You may use one of the "Chapter Approaches" of the actual CABO Model Energy Code 1995 Edition.
At the time a permit is requested, you shall state how you plan to meet the Georgia State Energy Code. When using this method you are not required to turn in any additional paperwork.
* Sloped ceilings, such as cathedral & tray ceilings, which require batt insulation, and HVAC platforms may be insulated with R-19 batts, provided the R-19 batts do not exceed 25% of the total ceiling area and provided the flat portion of the ceilings is insulated to R-30.
