The Montgomery County Council unanimously passed a ban on roadway sealants that contain coal tar Tuesday. It passed despite opposition from some private contractors who use sealants that contain coal tar, which is listed as a "possible" human carcinogen by the federal EPA.
"These coal tar pavement products, which are not even being used by our county department of transportation because of the concerns that they have, why would we then allow for them to be used by private residents when we as a county wouldn't do that?" Council member Craig Rice, sponsor of the bill, said Tuesday.
Last year, elevated levels of pollution thought to be caused by sealants with coal tar were found in sediment in a lake in Montgomery Village.
