Regular City Council Meeting Monday, May 23,2011 Page 20 Mr. Schwartz advised that most hardware stores and big box retailers had stopped selling the coal tar-based products, and those asphalt-based products were not demonstrating issues similar to coal tar-based products; noting that coal tar-based products were still available to vendors going door-to-door selling driveway seal coating services. Mr. Neprash advised that independent vendors could easily move from coal tar- based to asphalt-based applications, using their same equipment, with minimal and basically one-time cleaning and retrofitting of their equipment. Councilmember Johnson questioned how, if the City adopted this philosophy to no longer allow this product, how would it be policed and enforced without major cost to the City. Mr. Schwartz advised that would be a problem, with no resources available to pa- trol neighborhoods and take samples. Mr. Schwartz suggested that education was the City's best tool at this time to alert people to the City's ban on these types of product and their rationale for that ban to address water quality issues. Mr. Schwartz expressed hope that homeowners would ask questions of independent vendors and get documentation from them stating their products were not coal tar- based and therefore legal for use in Roseville. Councilmember Johnson questioned if the products would then be illegal for sale in Roseville. Mr. Neprash assured Councilmembers that Roseville was not the only City to adopt such an ordinance; and as more cities adopted such legislation, it would be- come wider known and standard practice among vendors. Councilmember Pust questioned if existing coal tar-based coatings should be re- moved before applying an asphalt-based coating. Councilmember Pust ques- tioned the connection between the dust coming off the coal tar-based coating into the home and exposure to children; and whether even if you never seal coated a driveway again, would that dust exposure continue. Mr. Neprash advised that he had not heard such a recommendation for removal from his various sources. Mr. Schwartz advised that these products had a relatively short life cycle: 2-4 years. Councilmember Pust moved, and Councilmember Johnson seconded adoption of an ordinance banning coal tar-based products.
