SUBSLAB DEPRESSURIZATION SYSTEM (Passive). A system designed to achieve lower sub-slab air pressure relative to indoor air pressure by use of a vent pipe routed through the conditioned space of a building and connecting the sub-slab area with outdoor air, thereby relying on the convective flow of air upward in the vent to draw air from beneath the slab.

 

SUBSLAB DEPRESSURIZATION SYSTEM (Active). A system designed to achieve lower sub-slab air pressure relative to indoor air pressure by use of a fan-powered vent drawing air from beneath the slab.

 

ROUGH-IN SUBSLAB DEPRESSURIZATION SYSTEM. A system complying with sections AF103.2, AF103.3, AF103.5, AF103.6, AF103.7, AF103.8, AF103.9.1, AF103.10 and AF103.11.    

DRAIN TILE LOOP. A continuous length of drain tile or perforated pipe extending around all or part of the internal or external perimeter of a basement or crawl space footing.

 

RADON GAS. A naturally-occurring, chemically inert, radio- active gas that is not detectable by human senses. As a gas, it can move readily through particles of soil and rock and can accumulate under the slabs and foundations of homes where it can easily enter into the living space through construction cracks and openings.

 

SOIL-GAS-RETARDER. A continuous membrane of 6-mil (0.15 mm) polyethylene or other equivalent material used to retard the flow of soil gases into a building.

 

SUBMEMBRANE DEPRESSURIZATION SYSTEM. A system designed to achieve lower-sub-membrane air pressure relative to crawl space air pressure by use of a vent drawing air from beneath the soil-gas-retarder membrane.

 

5-334                    Section AF103.1 of the International Residential Code is hereby amended to read as follows:

 

AF103.1 General.  The following construction techniques are intended to resist radon entry and prepare the building for post-construction radon mitigation, if necessary (see Figure AF102). These techniques are required in areas where designated by the jurisdiction.

 

Exception: The installation of a rough-in subslab depressurization system as defined in section AF102.1 shall be permitted.

 

5-335                    Section AF103.9 of the International Residential Code is hereby amended to read as follows:

 

AF03.9 Vent pipe identification.  All exposed and visible interior radon vent pipes shall be identified with at least one label on each floor and in accessible attics. The label shall read: “Radon Reduction System.”

 

AF103.9.1  Rough-in Subslab depressurization system pipe identification.  All exposed and visible interior radon vent pipes installed as part of a Rough-in subslab depressurization system as defined in section AF102.1 shall be identified with at least one label on each floor and in accessible attics. The label shall read: “This vent pipe is part of a rough-in for a radon reduction system. This system is not currently operational.  This is not part of the plumbing system.”

 

 

Section 3.  This ordinance shall be in full force and take effect on January 1, 2008, and after its publication as provided by law.
