EPA's October 2026 proposal would cut low-production well sites to quarterly AVO. What leak monitoring marginal well sites owe today, and what did not change.
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 2,000-gallon propylene tank holds 8,600 lb, under the 10,000 lb PSM threshold. Two general duty clauses and 29 CFR 1910.110 reached that site anyway.
A fire does not exempt a burned building from the asbestos NESHAP. What applies when a fire damaged structure is demolished, who files, and what six states add.
A Kansas quarry carries five environmental permits from three divisions in two departments, and three are not KDHE's. The map, and the October 31 clock.
No federal rule requires an asbestos operations and maintenance program for a commercial building. Two sourced tables split the required duties from the rest.
Half the contractor requirements in a manufacturing plant RFP carry a CFR section. The other half are the owner's choice, and they narrow the bidder field.
A manufacturing plant does not owe one list of dates. It owes four, on four different clocks. Here is every recurring federal obligation with its CFR citation.
Your EHS manager left. Almost nothing lapses legally, because the duties bind the employer. Here is what does lapse, with the cited 30, 60 and 90 day fix.
40 CFR 262.15(a) ties satellite accumulation to the process operator. What that means for in-plant waste handling in a manufacturing plant, and who may move it.
Federal metal finishing cadmium sits at 0.69 mg/L. A Kansas City metro city sets 0.020 mg/L for the same metal. What your pretreatment permit requires.

Chrome plating and anodizing fall under 40 CFR 63 Subpart N even at area sources. The rest of the shop falls under 6W. How to tell which rule covers which tank.
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.
EPA's RRP rule does not cover most commercial or industrial buildings. Here is what governs a plant renovation instead: OSHA 29 CFR 1926.62 and RCRA waste testing.
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.
A new spray booth usually needs state pre-construction authorization before install. Run the potential to emit math, then check the trigger in six states.
A stainless or chrome-alloy changeover triggers additional exposure monitoring under 29 CFR 1910.1026(d)(2)(vi). What that means for Cr(VI), manganese, and who gets sampled.
Colorado's ECMC takes over Class VI carbon storage well permits on November 12, 2026. Here is what OSHA still requires at your CO2 capture and compression skid.
Missouri narrowed its construction permit exemption for emergency generators on January 30, 2026. One generator still qualifies. Two or more is a calculation.
