Maryland Coal Tar Pavement Sealer Ban

Takes Effect January 1, 2016

Effective January 1, 2016 the sale, application and use of asphalt pavement sealers which contain coal tar are banned for use in Anne Arundel County & Prince Georges County Maryland.  A similar ban took effect for Washington D.C. in 2009 and Montgomery County Maryland in 2012.

There has been an ongoing controverty surrounding the use of pavement sealers containing refined coal tar (RT-12) which surrounds the amount of P.A.H.'s, (Polycyclic Aromatic Hydrocarbon) and their storm water runoff.  


Great, Now What...Does This Mean More Frequent Asphalt Milling & Paving?

Asphalt Seal Coating, as part of a Preventative Maintenance Program, is recognized as the most benefical application to double or tripple the life of your asphalt parking lot.  Without parking lot sealcoating, pavement life would be decreased from 20 to 10 years.  In addition, more expensive asphalt milling and asphalt paving would be required. This would require the use more natural resources (sand and stone) and require the use of more greehouse gasses.  This ranging from the equipment used to mill up the old asphalt to the hauling and manufacturing of the new asphalt.  

Good News- There Is A Coal Tar Alternative:

Asphalt Emulsion Pavement Sealers are a Coal Tar Alternative and contain minimal to zero P.A.H.'s.  Asphalt Emulsion Pavement Sealers will still allow you to implement a Preventative Maintenance Plan for your asphalt parking lot, so to prevent costly milling and paving.

Asphalt Emulsion Pavement Sealers require a more specialized application to give the same performance as coal tar, along with a professional seal coating company.  Please see our blog post:  How To Guarantee Your Sealcoating Jobs Will Last
