The Safe Drinking Water Act (SDWA), as
amended in 1996, requires that the U.S. Environmental Protection
Agency (EPA) review existing National Primary Drinking Water
Regulations (NPDWRs) no less often than every six years. This
cyclical evaluation is referred to as the "Six-Year Review".
Through the Six-Year Review process, EPA reviews existing NPDWRs
and evaluates whether potential revisions are appropriate to
maintain or improve the health of those persons served by public
water systems. EPA completed and published the review for the first
Six-Year Review cycle (1996-2002) on July 18, 2003 (68FR 42908).
The occurrence assessments conducted for the first Six-Year Review
were based on compliance monitoring data from 1993 to 1997, which
were provided by States. EPA expects to complete and publish the
review results for the second Six-Year Review cycle (2003-2009) in
the near future. The occurrence assessments conducted for the
second Six-Year Review are based on data collected between 1998 and
2005 and voluntarily submitted by States and other primacy agencies
under the current Information Collection Request (ICR No. 2231.01,
71 FR 32340). EPA's Office of Water is renewing the current ICR and
requesting that States and other primacy agencies voluntarily
provide historical compliance monitoring (contaminant occurrence
and treatment technique) data for community water systems (CWSs)
and non-transient non-community water systems (NTNCWSs) to the
Agency for support of future Six-Year Reviews. The Agency is
requesting monitoring data collected from 2006 to 2011 for all
regulated chemical, radiological and microbiological contaminants,
as well as as data from the Ground Water Rule (GWR), Surface Water
Treatment Rules (SWTRs), Long Term 1 and 2 Enhanced Surface Water
Treatment Rule (LT1 and LT2) and Interim Enhanced Surface Water
Treatment Rule (IESWTR), Stage 1 and 2 Disinfectants and
Disinfection Byproducts Rules (DBPRs), and Filter Backwash
Recycling Rule (FBRR). This collection request is a renewal of the
current ICR (ICR No.2231.01, 71 FR 32340) with the addition of
requesting treatment technique information from GWR, SWTRs, LT1,
LT2, IESWTR, DBPRs and FBRR. The compliance monitoring records in
this information collection (including all results for analytical
detections and non-detections) and treatment technique data will
provide the data needed to conduct statistical estimates of
national occurrence for regulated contaminants and will assist in
the evaluation of regulation effectiveness. These national
occurrence estimates and treatment technique information will
support the SDWA section 1412(b)(9) mandate that requires the
Agency to review the existing NPDWRs and determine whether
revisions are appropriate. In addition, SDWA section 1445(g)
requires the Agency to maintain a national drinking water
contaminant occurrence database (i.e., the National Contaminant
Occurrence Data (NCOD)) using occurrence data for both regulated
and unregulated contaminants in public water systems (PWSs). This
data collection will provide new occurrence data on regulated
contaminants to maintain the NCOD. It is in the interest of the
Agency to minimize the burden on States (and other primacy
agencies) by allowing submission of data in virtually any
electronic format, and to provide States that use the Safe Drinking
Water Information System State Versions (SDWIS/State) with
extraction scripts if wanted.
This ICR is a renewal of ICR
No. 2231.01 (71 FR 32340). The increase in burden hours and costs
reflect the slight modification in the scope (i.e., to request data
for several additional rules such as Ground Water Rule (GWR),
Surface Water Treatment Rules (SWTRs), Long Term 1 and 2 Enhanced
Surface Water Treatment Rule (LT1 and LT2) and Interim Enhanced
Surface Water Treatment Rule (IESTR), Stage 1 and 2 Disinfectants
and Disinfection Byproducts Rules (DBPRs), and Filter Backwash
Recycling Rule (FBRR)).
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
and explain the reason in the Supporting Statement.
