Read these before you act on the answer
- Requirements below are what we have read and cited directly from Authorization to Discharge Stormwater Under the NPDES and the Arkansas Water and Air Pollution Control Act (Construction General Permit ARR150000), 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.
- AR specifies stabilization INITIATION deadlines but not an acreage-tiered stabilization COMPLETION deadline like federal Table 2. AR does not specify a fixed day-count deadline for submitting a Notice of Termination after final stabilization (only that the operator 'may submit' the NOT once stabilized), so deadline.not.submission was omitted. No distinct 'identify corrective action within X hours' documentation deadline separate from the 3-business-day repair-completion deadline was found.
- No preparer credential was found for Arkansas. 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.
