including cellulose, polyethylene, and ceramic fibers, and clay, talc, wollastonite, calcium carbonate, and silica gel thickeners. The estimation of market shares and prices of the substitute formulations in the event of an asbestos ban relies to a large degree upon educated judgments of industry experts. Table 4 summarizes the findings of this analysis, and presents the data for the Asbestos Regulatory Cost Model. If asbestos was made unavailable, perhaps 87 percent (see Attachment A) of the asbestos containing roofing compounds market would be taken by formulations containing cellulose fibers in combination with clay and mineral thickeners. Identified most often by current and former asbestos processors and Gardner Asphalt, a company with a large share of asbestos containing roofing products market, this replacement fiber is cheaper than polyethylene fiber and seems to perform adequately in reinforcement. Prices would be expected to rise 18.5 percent (see Attachment B) to $2.95 per gallon due to increased costs of production (ICF 1986). Formulations containing polyethylene fibers, in conjunction with clay and mineral thickeners, are estimated to account for 8 percent of the asbestos-based roofing compounds (see Attachment A). These fibers costing 3 or 4 times more than cellulose on an equivalent basis tended to be favored by manufacturers of aluminum roof coatings. Prices of formulations bodied with polyethylene fibers would likely rise 35 percent (see Attachment B) to $3.36 per gallon due to increased costs (ICF 1986). The remaining 5 percent would be divided between other formulations containing clays, mineral fillers, silica gels, and ceramic fibers (see Attachment A). Prices of these compounds could be expected to rise 21.5 percent (see Attachment B) to $3.03 per gallon (ICF 1986). - 17 -
