Why this matters to the lake?
Most coal-tar-based sealcoat products consist of up to 35% coal-tar pitch, which contains high concentrations of polycyclic aromatic hydrocarbons (PAHs). A known human carcinogen, PAHs occur naturally in coal and petroleum products and are transported by different pathways into the environment. Sealcoats do not remain in place. Sealcoat particles are carried off by stormwater runoff and into receiving streams and the lake. PAHs that runoff into stormwater management areas can accumulate in the soil and cause soil contamination issues. In addition to human health and water quality concerns, PAHs have a negative effect on both terrestrial and aquatic ecosystems.
- Protect water quality by reducing pollution
- Protect human and environmental health by eliminating chemicals
Avoid the use of coal-tar-based sealcoating, or products that list components such as coal tar, refined coal tar, refined tar, and coal tar pitch. Alternative low PAHs options include asphalt based products, and pavement options such as pervious concrete, permeable asphalt and paver systems that do not require sealants. If applying the sealcoat yourself, follow all best practices.
- Two points are awarded for the use of alternative low PAHs sealcoating.
