No, coal tar is not universally banned across the entire United States. However, specific types of coal tar products, particularly coal tar-based sealants, are prohibited in many states and localities due to environmental and health concerns. These bans typically target the use and sale of products containing coal tar in pavement sealants, which have been identified as a source of polycyclic aromatic hydrocarbons (PAHs) in the environment.
Understanding Coal Tar Regulations in the US
While there is no nationwide federal ban on all coal tar products, individual states and local jurisdictions have implemented their own restrictions. These regulations vary, with some states enacting statewide prohibitions on the use and sale of coal tar-based sealants, while others have bans specific to certain cities, counties, or regions within their boundaries.
The primary reason for these bans is the presence of PAHs in coal tar. When coal tar-based sealants erode, these compounds can enter the environment, posing potential risks to aquatic life and human health.
States with Bans on Coal Tar-Based Sealants
Several states and the District of Columbia have taken action to restrict or ban coal tar-based sealants. These regulations aim to reduce environmental contamination and public exposure to harmful chemicals.
Below is a breakdown of states with current bans:
