Section 611.213  No Method of HPC Analysis

Sections 611.241(d)(2), 611.242(c)(2), 611.261(b)(8)(G), 611.262(b)(3)(G), 611.532(f)(2), and 611.533(c)(2) rely on this Section.  The Agency must determine that a system has no means for having a sample analyzed for HPC based on specific site-specific conditions:

a)         There is no certified laboratory that can analyze the sample within the time and temperatures the Board Note appended to Section 611.531(a)(2)(A) specifies;

b)         The supplier provides adequate disinfection in the distribution system, considering certain factors:

1)         Other measurements showing the presence of RDC in the distribution system;

2)         The distribution system size; and

3)         The adequacy of the supplier's cross connection control program; and

c)         The PWS cannot maintain an RDC in its distribution system.

BOARD NOTE:  This Section derives from 40 CFR 141.72(a)(4)(ii).
