The EPA is required by the Safe
Drinking Water Act (SDWA), as amended in 1996, to review existing
National Primary Drinking Water Regulations (NPDWRs) no less often
than every six years. This routine evaluation is referred to as the
“Six-Year Review of National Primary Drinking Water Regulations” or
simply, the “Six-Year Review.” Throughout the Six-Year Review
process, the EPA assesses new data to determine risks to human
health posed by regulated drinking water contaminants and
identifies NPDWRs that may be appropriate for revision. The EPA
completed and published review results for the first Six-Year
Review cycle (1996-2002) on July 18, 2003 (68 FR 42908). The
occurrence assessments for the first Six-Year Review were based on
compliance monitoring from a cross-section of 16 States, collected
from 1993 to 1997, which were voluntarily provided by the States.
The EPA completed and published review results for the second
Six-Year Review cycle (2003-2009) on March 29, 2010 (75 FR 15500).
The occurrence assessments conducted for the second Six-Year Review
are based on data collected between 1998 and 2005, voluntarily
submitted by States and other drinking water primary enforcement
(primacy) agencies (i.e., the District of Columbia, the
Commonwealth of Puerto Rico, the Virgin Islands, Guam, American
Samoa, the Commonwealth of the Northern Mariana Islands, the Trust
Territory of the Pacific Islands, or an eligible Indian tribe). The
EPA completed and published review results for the third Six-Year
Review cycle (2010-2016) on January 11, 2017 (82 FR 3518). The
occurrence assessments conducted for the third Six-Year Review are
based on contaminant occurrence and treatment techniques data
collected between 2006 and 2011, voluntarily submitted by States
and other drinking water primacy agencies. The EPA created this new
ICR to continue to engage States and other drinking water primacy
agencies in data collection efforts. For this ICR, the EPA is
soliciting States and other primacy agencies to (voluntarily)
provide historical, compliance monitoring (contaminant occurrence)
data for community water systems (CWSs) and non-transient
non-community water systems (NTNCWSs) to the Agency in support of
the fourth Six-Year Review. The EPA is requesting contaminant
occurrence and treatment technique data collected from 2012 to 2019
for all regulated chemical, radiological, and microbial
contaminants, including data collected for the Revised Total
Coliform Rule, newly promulgated since the third Six-Year Review
information collection. The compliance monitoring records for this
information collection (including all results for analytical
detections and non-detections) provide the data needed to conduct
statistical estimates of national occurrence for regulated
contaminants and evaluate treatment technique information
associated with the control of pathogens, disinfectants, and
disinfection byproducts. The national occurrence estimates and
information on treatment techniques will support the EPA’s review
of existing NPDWRs as required by the SDWA, section 1412(b)(9). In
addition, the SDWA, section 1445(g), requires the EPA to maintain a
national drinking water contaminant occurrence database (i.e., the
National Contaminant Occurrence Database (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.
The new burden under this ICR
is for a one-time data collection effort in support of the fourth
six-year review of national primary drinking water
regulations.
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.
