This ICR is approved. As EPA prepares its report on drinking water needs using the results of this survey, EPA should conduct a comprehensive uncertainty analysis that quantifies undertainty where possible, and discusses unquantifiable uncertainty qualitatively, including discussion of potential magnitude of unquantifiable uncertainty. Use of sensitivity analyses is also encouraged to asses the relative importance of various sources of uncertainty.

The Environmental Protection Agency (EPA) will conduct an assessment to estimate the capital investment needs for drinking water systems eligible to receive Drinking Water State Revolving Fund (DWSRF) monies. The nationwide assessment will be conducted by the Drinking Water Protection Division (DWPD) of EPAÂs Office of Ground Water and Drinking Water (OGWDW). The data collection is authorized by Sections 1452(h) and 1452(i)(4) of the Safe Drinking Water Act (SDWA) and will be used to estimate the cost of providing safe drinking water to consumers over a 20-year period. The data from the report will also be used to allot DWSRF monies among states. The focus of the 2007 DWINSA is collecting information on systems needs and on the projected costs associated with those needs. All states have committed to help EPA administer the 2007 DWINSA with at least the minimum of activities. Thirteen states have chosen not to participate in the statistical portion of the survey (i.e., collecting data from systems serving 3,301  100,000 people). For the states that opt out of the statistical portion of the survey, the needs of the participating states will be used to determine the needs for systems serving 3,301  100,000 people. All states with systems serving more than 100,000 people will participate in census portion of the survey.
For the 2007 DWINSA, EPA will conduct a census of all community water systems (CWSs) serving populations more than 100,000 and select a random sample of CWSs that serve populations of 3,301 Â 100,000. EPA will conduct a site visit for 600 randomly selected CWSs serving 3,300 and fewer people and will estimate infrastructure needs for not-for-profit noncommunity water systems (NPNCWSs) in the states and all Alaska Native and American Indian systems based on the 1999 DWINSA.
EPA will send the data collection instrument to all CWSs serving more than 100,000 people and a random sample of CWSs serving between 3,301 and 100,000 people (i.e., medium and large system sample). The data collection instrument consists of project tables in which the water systems list all their capital improvement projects through the year 2026. The same data collection instrument will be used for CWSs serving a population of 3,300 and fewer (i.e., small system sample); however, the data collection instrument will be completed by an EPA site visit contractor.
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.
