Where dry cleaning was done on site, SBA requires a Phase I followed by a Phase II no matter what the Phase I concluded. The rule and the state fund money.
A Phase 1 ESA is a non-invasive investigation under ASTM E1527-21 that identifies environmental conditions before a property deal. What it covers, costs, and contains.
Formaldehyde at 0.6 ppm is under the 0.75 ppm PEL and still over the action level, which starts 6-month monitoring and medical surveillance under 1910.1048.

A water loss in a Kansas commercial building raises one question above all others: what has to happen before people can use the space again. The answer is not a regulatory number, because no federal mold standard exists.

There is no federal mold standard and no legal limit for airborne mold. Here is what air, surface and bulk samples establish in a commercial building, what they cannot establish, and the three situations where sampling is worth the money.
OSHA's construction lead standard presumes exposure for named demolition, blasting and torch-cutting tasks and demands full protection on day one, before any lab result exists.
