Check the permit: no written limit or plant report supports these values of EPA's. Each is a nutrient limit under 0.0005 mg/L, a unit the parameter is not measured in, or a median over 1,000 times the limit. Read the permit before relying on it.
Cited limits by parameter: Ohio's rules and the federal ones.
