Relates to the definition of coal tar and its use in pavement products

This bill amends New York's environmental conservation law to define "coal tar" for pavement products. It specifies that coal tar is a thick liquid from coal distillation containing polycyclic aromatic hydrocarbons (PAHs) above 1,000 milligrams per kilogram. The definition explicitly includes certain residues like ethylene or steam cracked residues. This change directly affects manufacturers and suppliers of pavement materials using coal tar, as it sets a clear regulatory threshold for PAH levels. The bill was advanced to third reading in April 2025 but was later substituted by S3179.
