significant quantity. Concrete from demolition operations is expected to be eventually disposed of to landfill. The notified polymer may have potential for biodegradability. However, this is not considered a concern due to the limited release expected from the reformulation process. Bioaccumulation is not likely based on its high molecular weight and the use pattern of being trapped in concrete solids after application. In landfill, leaching of the notified polymer is not expected given it is trapped in the concrete matrix. With time, it will be degraded via abiotic or biotic pathways into water and oxides of carbon and inorganic salts. Therefore, based on its assumed low hazard and reported use pattern, the notified polymer is not considered to pose an unreasonable risk to the environment.
