The bidder shall submit a project plan using the design standards below that is in compliance with all applicable HUD, EPA and State of Illinois regulations as well as all local building and zoning codes.

Subcontractors that will be required should be clearly identified in the project plan. Short-term tests may last between (2) two and (90) ninety days. Most last between(2) two and (7) seven days. Examples of short-term detectors include: activated charcoal canisters, charcoal liquid scintillation vials, electret chambers and continuous radon monitors. Be aware that any tests lasting less than a week (that is, most short-term tests) require closed-house conditions. Closed-house conditions mean keeping all windows closed, keeping doors closed except for normal entry and exit, and not operating fans or other appliances which bring air in from outside (except for fans that are part of a radon reduction system, or small exhaust fans that operate for only short periods of time). • Before Testing: Begin closed-house conditions at least 12 hours before the start of the short-term test. • During Testing: Maintain closed-house conditions during the entire duration of the shortterm test, especially for tests less than one week in duration. • Operate home heating or cooling systems normally during the test. For testslasting less than one week, only operate air conditioning units that recirculate interior air. Collecting radon prior to entry into the building and discharging it to a safe location. Mitigation Systems in Illinois must include: Effective radon reduction Unobtrusive and permanent installation Quiet operation, Energy efficient operation and maintenance Sub-Slab Depressurization (SSD). Active Sub-slab depressurization uses a fan to draw radon from beneath the house. SSD systems collect radon prior to entry and exhaust it to a safe location above the highest eave.
