could be used without causing indoor Formaldehyde concentrations that result in CEQA <br />cancer risks that substantially exceed 10 per million for occupants with continuous <br />occupancy <br />If CARD Phase 2 compliant composite wood products are utilized in construction, then the <br />resulting indoor formaldehyde concentrations should be determined in the design phase <br />using the speck amounts of each type of composite wood product, the specific <br />formaldehyde emission rates, and the volume and outdoor air ventilation rates or the indoor <br />spaces, and all feasible mitigation measures employed to reduce this impact (e.g. use less <br />formaldehyde containing composite wood products andlor incorporate mechanical systems <br />capable of higher outdoor air ventilation rates). See the procedure described earlier (i.e., <br />Pre -Construction Building Material/Furnishing Formaldehyde Emissions Assessment) to <br />insure that the materials selected achieve acceptable cancer risks from material orygassing <br />of formaldehyde. <br />PStcmai vely, and perhaps a simpler approach, is to use only composite wood products (e.g. <br />hardwood plywood, medium density fiberboard, particleboard) for all interior finish <br />systems that are made with CARB approved no -added formaldehyde (NAF) resins or ultra - <br />low emitting formaldehyde (ULEF) resins. These products are now readily available and <br />many other projects such as the AC by Marriott Hotel — West San Jose Project and 2525 <br />North Main Street, Santa Ana have entered into settlement agreements stipulating the use <br />of composite wood materials only containing NAF or ULEF resins. <br />19 of 19 <br />►39 <br />75C-56 <br />
