Environmental and Regulatory Compliance
What this domain tests
Permits, stormwater, asbestos and lead, wetlands, air, waste, and Montana DEQ compliance.
Core rules
- Construction stormwater: disturb 1 acre or more, or part of a larger common plan, requires MPDES Construction General Permit coverage, a SWPPP, a Notice of Intent, inspections, and a Notice of Termination.
- Erosion and sediment control: silt fence, inlet protection, stabilized entrance, dust control; inspect weekly and after significant rain.
- Asbestos: NESHAP 40 CFR 61 Subpart M before renovation or demolition; Montana DEQ notification; lead RRP under 40 CFR 745 for pre-1978 housing.
- Wetlands and streams: Section 404 Corps permit; Montana Stream Protection Act 124 permit; floodplain permits.
- Hazardous waste and spills: DEQ reporting; air: open-burning permits and dust control.
Worked example
A 2-acre commercial site needs an NOI, SWPPP, controls installed before grading, posted notice, inspections, and an NOT once stabilized. A 0.8-acre parcel that is part of a 3-acre common plan still crosses the 1-acre threshold.
Traps
Assuming a small parcel avoids the permit; grading before the SWPPP; no NOT; no asbestos survey; disturbing a stream without permits.
