What compliance challenges exist when using coal tar emulsion asphalt sealers?

[Nicolás]

Compliance challenges include bans or restrictions in many cities and states, stormwater permits that limit PAH discharge, and disposal rules for wash water and residues. Coal tar products can also trigger stricter worker protection requirements and site containment measures during application. For commercial properties, liability concerns arise if runoff contaminates drains or waterways. Documentation demands tend to be higher: SDS scrutiny, product verification, and sometimes third party environmental approvals. These challenges often push owners toward asphalt emulsions even if coal tar performance is well known.
