§141.564. My system practices lime softening—is there any special provision regarding my individual filter turbidity monitoring?
40 C.F.R. § 141.564
If your system utilizes lime softening, you may apply to the State for alternative turbidity exceedance levels for the levels specified in the table in § 141.563. You must be able to demonstrate to the State that higher turbidity levels are due to lime carryover only, and not due to degraded filter performance.
