Field staff for the Watershed Protection Department watch for sealant applications in progress and freshly sealed parking lots as they drive throughout the city on their other job duties. Newly applied sealants are screened for the presence of high PAHs. Enforcement action is taken when high PAH pavement sealant is found to be applied after the ban was initiated. Enforcement action through municipal court typically involves remediation of the applied sealant. The requirement for remediation is full removal of the applied sealant and fines.
The city produces and disseminates educational materials to producers, applicators, buyers, and to the general public through various means. City staff also periodically checks distributors to monitor product on their shelves.
Citizens may call in suspected high PAH applications to the City’s 24-Hour Pollution Hotline at 512-974-2550.
