Section 611.500  Consecutive PWSs

When a PWS supplies water to one or more other PWSs, the Agency must modify the monitoring requirements imposed by this Part to the extent that the interconnection of the PWSs justifies treating them as a single PWS for monitoring purposes.  Any modified monitoring must be conducted under a schedule specified by a SEP.  The Agency must not approve such modified monitoring without the concurrence of USEPA.

BOARD NOTE:  Derived from 40 CFR 141.29 (2002).
