Correct Answer: Option D — A device that produces a fecal coliform bacteria count not greater than 200 per 100 milliliters and suspended solids not greater than 150 milligrams per liter.
A Type II MSD is a flow-through device designed for larger vessels, providing a higher level of treatment than Type I. It must produce an effluent with a fecal coliform count not greater than 200 per 100 milliliters and suspended solids not greater than 150 milligrams per liter.
