Assemble a per-job coal-tar/high-PAH sealant legality checklist for a multi-state sealcoating contractor, since no single national API or registry tracks the current patchwork of state and county bans.

Steps
Start from an unofficial index like Coal Tar Free America's bans page to identify candidate jurisdictions — treat it as a starting point, not a citable legal source.
For each job's state, pull the actual state statute or state agency guidance page directly.
For jobs in states without a state-level ban, separately check county/municipal code for the specific project address.
Note that PAH-content thresholds differ by jurisdiction (e.g., 0.1% in Austin vs. 1% in Virginia) — don't assume a uniform national threshold.
Re-verify before every out-of-territory bid, since new local bans are added periodically.
Known gotchas
Honest negative: there is no authoritative, machine-readable national API for coal-tar/PAH sealant bans — every jurisdiction must be checked against its own primary legal source per job.
County bans can be stricter than, layered on top of, or exist entirely independent of state law (e.g., Wisconsin has no statewide ban but Dane County has a local one) — state-level clearance doesn't guarantee county-level clearance.
