Current through Register Vol. 48, No. 28, July 12, 2024
A supplier must report specific information to the Agency as
				  this Section provides.
a) Reporting
				for Tap, Lead, and Copper, and Water Quality Parameter Monitoring
1) Notwithstanding Section
				611.840(a) and
				except as subsection (a)(1)(H) provides otherwise, a supplier must report the
				information subsections (a)(1)(A) through (a)(1)(I) specify for all samples and
				for all water quality parameter samples Section
				611.357 specifies within ten
				days after the end of each applicable tap sampling period Sections
				611.356 and
				611.357 specify (i.e., every six
				months, annually, triennially, or every nine years). For a tap monitoring cycle
				shorter than six months, the end of the tap monitoring cycle is the last date
				on which the supplier may collect samples during that tap sampling period, as
				Sections 611.356 and
				611.357 specify.
A) The results of all tap samples for lead
				and copper, including the location of each site and the criteria under Section
				611.356(a)(3) through
				(a)(10) the supplier used as the basis for
				selecting the site for its sampling pool, accounting for Section
				611.356(a)(11);
B) Supporting documents for each tap water
				lead or copper sample the supplier requests the Agency invalidate under Section
				611.356(f)(2);
C) A supplier having lead, galvanized
				requiring replacement, or lead status unknown service lines in its lead service
				line inventory under Section
				611.354(a) must
				re-evaluate the tap sampling locations the supplier uses in its sampling pool
				prior to the compliance date Section
				611.350(a)
				specifies, then the more frequent of annually or prior to the each subsequent
				round of tap sampling the supplier conducts, whichever is more frequent;
i) Before the first applicable tap monitoring
				cycle under Section 611.356(d), the
				supplier must submit a site sample plan to the Agency under Section 611.356,
				including a list of tap sample site locations identified in the inventory under
				Section 611.354(a), and
				a list a tap sampling WQP sites the supplier selected under Section
				611.357(a)(1).
				The supplier must update and submit the site sample plan to the Agency before
				changing any sample site locations. The Agency may issue a SEP requiring the
				supplier to modify its site sample plan as necessary.
ii) For a supplier having lead service line
				sites but an insufficient number to meet the minimum number Section
				611.356 requires, the supplier
				must document support for its conclusion that it has an insufficient number of
				lead service line sites complying with the applicable of
				40 CFR Section
				141.86(a)(3) or (a)(4) (for
				a CWS supplier) or 40 CFR
				Section 141.86(a)(8) (for an
				NTNCWS supplier);
D) The
				90th percentile lead and copper concentrations the
				supplier measures from among all lead and copper tap samples the supplier
				collects during each tap sampling period (calculated under Section
				611.350(c)(4)),
				unless the Agency calculates the supplier's 90th
				percentile lead and copper concentrations under subsection (h);
E) With the exception of initial tap sampling
				under Section 611.356(d)(1),
				the supplier must identify any site it did not sample during previous tap
				sampling periods and explain why sampling sites have changed;
F) The results of all water quality parameter
				tap samples the supplier must collect under Section
				611.357(b) through
				(g);
G) The results of all samples the supplier
				collects at entry points for applicable water quality parameters under Section
				611.357(b) through
				(e);
H) A supplier must report the results of all
				water quality parameter samples the supplier collects under Section
				611.357(c) through
				(f) during each six-month water quality
				monitoring period Section
				611.357(d)
				specifies within the first ten days following the end of the water quality
				monitoring period, unless the Agency specifies a more frequent reporting
				requirement in a SEP; and
I) Before
				the first applicable tap sampling period under Section
				611.356(d), the
				supplier must submit to the Agency, a copy of the tap sampling protocol the
				supplier provides to persons sampling. The Agency must verify that the supplier
				uses wide-mouth collection bottles and the supplier does not recommend
				pre-stagnation flushing or aerator cleaning or removal before collecting
				samples under Section
				611.356(b). The
				tap sampling protocol must contain instructions for correctly collecting a
				first draw sample at a site without a lead service line and a first draw and a
				fifth liter sample at a site with a lead service line, as applicable. If the
				supplier seeks to modify the tap sampling protocol it submitted this subsection
				(a)(1)(I), the supplier must submit the updated version of the protocol to the
				Agency for review and approval at least 60 days before using it.
