Managing pharmaceutical waste

Waste pharmaceuticals can affect the environment if they are not properly managed. Pharmaceuticals have been detected in water, sediments, and fish. We regulate businesses to ensure they properly manage waste pharmaceuticals.

As the agency charged with protecting Washington's environment, we also offer resources and technical assistance to help healthcare facilities comply with the law and protect the environment.

Who must follow the special requirements?

The special requirements for the management of dangerous waste pharmaceuticals (WAC 173-303-555) apply to health care facilities that:

  • Provide preventative, diagnostic, therapeutic, rehabilitative, or palliative care to improve the physical or mental condition of humans and animals,
    OR
  • Sell or distribute pharmaceuticals.

Step 1: Count ALL waste

To determine how to manage your dangerous waste pharmaceuticals, you must count BOTH your:

  • Pharmaceutical dangerous waste, AND
  • Nonpharmaceutical dangerous waste each month.

Unsure what types of waste you have? See our designation page.

Step 2: Check your waste count against monthly waste limits

Monthly waste limits (QEL)
2.2 pounds of dangerous waste with a quantity exclusion limit (QEL) of 2.2 pounds
220 pounds of dangerous waste with a QEL of 220 pounds
220 pounds of residue or contaminated soil, water, or other debris resulting from the cleanup of a spill to land or water of any dangerous waste with a QEL of 2.2 pounds.

Step 3: Determine your management options

Compare your waste count against the monthly waste limits to now determine your management option(s).

If your waste count in a month is:

  • Greater than ANY of the waste thresholds, follow the special requirements.
  • Less than ALL waste thresholds, you can choose to follow either:
    • Special requirements, or
    • Standard dangerous waste requirements.
