As of July 1, 2026, the Oregon Department of Environmental Quality (DEQ) has issued the new 2026–2031 1200-Z Industrial Stormwater Discharge General Permit, replacing the previous permit that expired on June 30. The renewed permit includes updated requirements that many industrial facilities must address to maintain compliance.
If your facility is covered under the 1200-Z permit, now is the time to review your stormwater program, update your Stormwater Pollution Control Plan (SWPCP), and ensure your Best Management Practices (BMPs) align with the new permit requirements.
What Is the 1200-Z Permit?
The 1200-Z permit regulates stormwater runoff from industrial facilities where rainwater may come into contact with industrial materials, equipment, or activities before leaving the site. It applies to many industries throughout Oregon, including manufacturing, transportation, warehousing, recycling, wood products, and waste management. Its purpose is to reduce pollutants entering Oregon’s waterways and protect water quality.
What Should Facilities Do Now?
The new permit is an opportunity to evaluate your stormwater compliance program and confirm it reflects current operations.
Key priorities include:
- Review and update your SWPCP to meet the new permit requirements and accurately document current site conditions, drainage patterns, and potential pollutant sources.
- Evaluate your BMPs to verify they effectively minimize stormwater pollution. This may include reviewing housekeeping practices, material storage, spill prevention procedures, employee training, inspections, and erosion controls.
- Maintain documentation and inspections to support ongoing compliance and prepare for potential DEQ inspections.
Taking these steps now can help reduce the risk of permit violations, benchmark exceedances, and costly corrective actions later.
