Arizona MSGP

The deadline for Arizona industrial facilities to renew their Multi-Sector General Permit (MSGP) for stormwater discharge is fast approaching. If your permit expired in 2024, you must act now to avoid serious penalties, including fines of up to $25,000 per day.

With stricter enforcement from the Arizona Department of Environmental Quality (ADEQ) and the Environmental Protection Agency (EPA), compliance is no longer optional—it’s a necessity for businesses operating in regulated sectors.

Understanding the MSGP and Why It Matters

The MSGP is a requirement for industrial facilities that may discharge stormwater into Arizona’s waterways. Facilities that store or process materials outdoors are particularly at risk of polluting water sources, making compliance a top priority for ADEQ.

Without a valid permit, your facility could face legal action, financial penalties, and even potential shutdowns.

Industries Affected by MSGP Regulations

If your facility falls into one of these high-risk categories, you need to ensure your permit is renewed before the April 2025 deadline:

  • Manufacturing (NAICS 31-33) – Includes chemical plants, metal processing, and paper mills.
  • Transportation & Warehousing (NAICS 48-49) – Trucking terminals, rail yards, and distribution centers.
  • Waste Management & Recycling (NAICS 562) – Landfills, recycling centers, and hazardous waste disposal.
  • Wholesale Trade (NAICS 42) – Facilities with outdoor material storage.
  • Construction Materials & Aggregate (NAICS 212) – Asphalt plants, rock crushing, and concrete batching.

If your permit expired in 2024, your facility must renew before April 2025.

Consequences of Failing to Renew Your MSGP

Non-compliance isn’t just a minor inconvenience—it carries significant legal and financial risks.
