Does a site in North Dakota need coverage
Worked for a one acre site as a reference point. Change the acreage in the tool below and the answer, and its reasoning, change with it.

Read these before you act on the answer
- Requirements below are what we have read and cited directly from General Permit for Stormwater Discharges from Construction Activities (NDR11-0000), not the federal CGP. A category we have not yet transcribed from this permit is omitted here rather than assumed to match EPA's rule.
- ND CGP (NDR11-0000) has no arid/semi-arid/drought-specific reduced inspection provision; instead it has a frozen-ground/winter earthwork-suspension provision and a reduced once-per-month inspection allowance for stabilized-but-not-fully-vegetated areas. ND structures stabilization completion deadlines by slope grade (3:1+ vs. other), not by 5-acre disturbed-area threshold, so state.nd.* ids are used. No explicit deadline was found for how quickly an inspection report must be written after the inspection. The permit contains no numeric turbidity/pH/TSS discharge limits; only BMP design/performance numeric criteria exist (sediment basin storage volume, 2-year/24-hour storm design standard, 0.25-inch rainfall inspection trigger), clearly labeled as design criteria, not discharge limits.
- No preparer credential was found for North Dakota. On what we have verified, a generated plan can be adopted by the operator without a credentialed signature. Local ordinances can still be stricter than state law.
- Basinwise does not perform the physical site inspections the permit requires. Those must be carried out on site by a qualified person.
