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.
