A significant industrial user is defined as what type of user?

• A. A federal categorical industrial user
• B. A small business
• C. A domestic user
• D. A municipal facility

Answer: (A)

In pretreatment programs, a significant industrial user is tied to regulatory oversight because their discharge must meet pretreatment standards. A federal categorical industrial user is defined as a facility that falls under EPA’s categorical pretreatment standards for specific industries and discharges to a publicly owned treatment works (POTW). These facilities are automatically considered significant because of the potential to cause interference or pass-through and because they must comply with strict federal limits. The other options describe general types of users that are not automatically classified as significant unless they meet additional regulatory criteria (such as large flow or causing contamination problems). So, the choice that matches the formal definition is the federal categorical industrial user.
