than the parameters for chlorine or chloramine specified in paragraph (b)(2)(i) of this
section the facility must—

Interpretive Guidance § 494.40(b)(2)(ii)(A)
“Corrective action” here could include backwashing carbon tanks, rebedding or replacement of
the tanks, or addition of an adjunct system such as chemical injection to address an extremely
high chlorine or chloramine load from the municipal supplier. In any case, testing must confirm
acceptable levels of chlorine/chloramine before dialysis treatments can resume. It could be
necessary to reschedule patient treatments, or for patients to be transferred to another facility
for one or more treatments.
