Last year we demonstrated the extent of coal tar sealant use in California as the state legislature considered a bill to ban coal tar sealants (see Surprising New Info on California Coal Tar Sealant Use). That really was a surprise to many that assumed such an environmentally-proactive state would have banned this nasty product years ago.
Now comes some even more amazing information from a Sierra Madre, a Los Angeles suburb. The town of about 10,000 earlier this year passed an ordinance amendment to their “One Family Residential” code with a focus on parking.
If you listen to the discussion by their city council, the intent was to control how and with what type of vehicle would be allowed in residential areas. There was no discussion about sealants at all. However the ordinance is prescriptive in the use of coal tar pavement sealants on asphalt surfaces as shown from a clip from the ordinance below.
Certainly if staff and council knew of the problems with coal tar sealant pollution this, at best, would have been silent on the issue. If you are new to this issue, may we suggest you review this interactive infographic about coal tar sealer pollution and its effects.
