Regulatory Briefing - Revised NDDH Industrial Stormwater Discharge General NPDES Permit
In addition to requirements to prepare and maintain a stormwater pollution prevention plan (SWPPP), two important compliance requirements for industrial dischargers in North Dakota are inspections and stormwater monitoring:
Inspections of Industrial Sites
A comprehensive inspection of the permitted facility’s stormwater control system must be made twice per year (January thru June, July thru December). At least one of the inspections should be conducted within 48 hours of a rainfall or snowmelt event resulting in a stormwater discharge. The personnel conducting site inspections must be familiar with permit conditions and the proper installation and operation of control measures. The inspections need to include discharge outlets from areas used for industrial activities, areas used for storage of materials, structural control measures, and vehicle maintenance areas.
Sampling Requirements
Only some facilities will be required to sample stormwater discharges as a condition of this permit. The minimum monitoring frequency is annual, except for discharges from large air transportation facilities.
