I understand it is challenging for coal tar manufacturers/applicators to switch to an asphalt-based product. But, like the lead-based paint and asbestos, we learn and things change. Coal tar manufacturers and applicators may have to admit the products they were defending weren't as safe or as superior as the new products available now. Manufacturers of asphalt formulas for years have been eliminating the problems and are finding better methods, ingredients, and processes to make the products even better. The ridiculous speculation in your article of a potential shortage in asphalt because of crude oil availability is just ignorant. Gasoline would be $5-plus a gallon (I don't think so). The bottom line is, manufacturers and applicators alike need to embrace the change and use it to their advantage. This is a chance for manufacturers to be environmentally responsible (and make more money at the same time) by taking advantage of the change in the industry. The applicators will benefit by putting down a product that is safer for them as applicators and is environmentally friendly. So, embrace the change and you may find out that's it's not really as bad as some would like you to believe.
