BETHESDA, Md.—Sometimes two words make all the difference.
The EPDM Roofing Association submitted a recommendation to the Environmental Protection Agency that it bases proposed environmental performance guidelines on “assessed risk” rather than the concept of “intrinsic hazard,” the association said.
The ERA said assessed risk would require data to show that the chemical is dangerous based on the way it is to be used and in the form that it is in, not just the theoretical danger that intrinsic hazard implies, the association said.
The ERA's biggest concern is that a range of widely used building products could be excluded from the market if the proposed guidelines are implemented as written.
The ERA listed a number of building envelope products that could be affected by the guidelines as written, the alleged hazardous materials they may contain and the reference list (in parentheses) from which the alleged hazard is identified:
- Thermoplastic roofing membranes: Titanium dioxide (California Prop 65);
- Rubber roofing membranes: Carbon black (California Prop 65);
- Asphaltic roofing and waterproofing products: Bitumen (California Prop 65);
- Reflective roof coatings: Titanium dioxide (California Prop 65);
- Fiber insulation: Wood dust (California Prop 65); and
- Foam insulation: Halogenated fire retardants (San Antonio Protocol).
