A facility is conditionally exempt from silver recovery requirements if it generates less than 500 gallons per month of silver-containing solution which is:

• A. 1 and 2
• B. 1 and 3
• C. 2 and 3
• D. 1, 2, and 3

Answer: (D)

Conditional exemptions for silver-containing waste depend on both how much you generate and the specific characteristics of that waste. If you produce less than 500 gallons per month and the silver-containing solution also meets all three described conditions, you qualify for the exemption. That means every one of the three conditions must be true for the exemption to apply. If any one of them isn’t met, the exemption doesn’t apply and standard silver recovery requirements would apply instead. In practice, track monthly generation and ensure the waste meets all the listed criteria to remain exempt.
