Steps
Fetch the current text at austintexas.gov's coal-tar-ban FAQ page.
Confirm the ordinance (effective January 1, 2006, amended October 17, 2019) prohibits sealants exceeding 0.1% (1,000 ppm) PAH by weight, not just coal-tar-labeled products specifically.
Verify the job site falls within Austin's full-purpose limits or ETJ, where the ordinance applies.
Request a current PAH lab analysis or manufacturer SDS for the proposed product.
Retain documentation in the job file in case of a compliance audit.
Known gotchas
The 2019 amendment broadened the rule from 'coal tar' specifically to any sealant over the 0.1% PAH threshold — some asphalt-based or recycled-content products can still fail this test.
ETJ boundaries shift over time; confirm current ETJ maps rather than assuming a suburban address is outside city authority.
