Reports & Testimonies

  • GAO’s recommendations database contains report recommendations that still need to be addressed.

    GAO’s recommendations help congressional and agency leaders prepare for appropriations and oversight activities, as well as help improve government operations. Recommendations remain open until they are designated as Closed-implemented or Closed-not implemented. You can explore open recommendations by searching or browsing.

    GAO's priority recommendations are those that we believe warrant priority attention. We sent letters to the heads of key departments and agencies, urging them to continue focusing on these issues. These recommendations are labeled as such. You can find priority recommendations by searching or browsing our open recommendations below, or through our mobile app.

    Recommendation: The Assistant Administrator for Water of EPA's Office of Water should require states to report available information about lead pipes to EPA's Safe Drinking Water Information System (SDWIS)/Fed (or a future redesign such as SDWIS Prime) database, in its upcoming revision of the LCR. (Recommendation 1)

    Agency: Environmental Protection Agency
    Status: Open

    Comments: When we confirm what action the agency has taken, we will update.
    Recommendation: The Assistant Administrator for Water of EPA's Office of Water should require states to report all 90th percentile sample results for small water systems to EPA's SDWIS/Fed (or a future redesign such as SDWIS Prime) database, in its upcoming revision of the LCR. (Recommendation 2)

    Status: Open

    Comments: When we confirm what action the agency has taken, we will update.
    Recommendation: The Assistant Administrator for Water of EPA's Office of Water and the Assistant Administrator of EPA's Office of Enforcement and Compliance Assurance should develop a statistical analysis that incorporates multiple factors--including those currently in SDWIS/Fed and others such as the presence of lead pipes and the use of corrosion control--to identify water systems that might pose a higher likelihood for violating the LCR once complete violations data are obtained, such as through SDWIS Prime. (Recommendation 3)

    Recommendation: To assess and validate the effectiveness of PHMSA's Risk Ranking Index Model (RRIM) in prioritizing pipelines for inspection, the Secretary of Transportation should direct the Administrator of PHMSA to document the decisions and underlying assumptions for the design of RRIM, including what data and information were analyzed as part of determining each component of the model, such as the threat factors, weights, risk tiers, and inspection frequency.

    Agency: Department of Transportation
    Status: Open

    Recommendation: To assess and validate the effectiveness of PHMSA's RRIM in prioritizing pipelines for inspection, the Secretary of Transportation should direct the Administrator of PHMSA to establish and implement a process that uses data to periodically review and assess the effectiveness of the model in prioritizing pipelines for inspection and document the results of these analyses.

    Recommendation: To ensure that DOE's long-term plans for storing waste in the existing SSTs and DSTs at Hanford consider the condition of the tanks and the WTP construction delay, the Secretary of Energy should assess the extent to which the factors that may have led to corrosion in AY-102 are present in any of the other 27 DSTs.

    Agency: Department of Energy
    Status: Open

    Comments: As of Nov. 23, 2016, DOE is still working to empty the waste from the leaking tank as required by a 2014 settlement agreement with the State of Washington (scheduled to be complete in March 2017). Once the tank is emptied, DOE plans to assess the cause of the leak and begin to address the recommendation. When we confirm what actions DOE has taken in response to this recommendation, we will provide updated information.
    Recommendation: To ensure that DOE's long-term plans for storing waste in the existing SSTs and DSTs at Hanford consider the condition of the tanks and the WTP construction delay, the Secretary of Energy should update the schedule for retrieving waste from the tanks, taking into consideration (1) the impact of the delays in the WTP, (2) the risks associated with continuing to store waste in aging tanks, and (3) an analysis of available DST space.

    Agency: Department of Energy
    Status: Open

    Comments: As of Nov. 23, 2016, DOE plans to update its Hanford Site System Plan by October 2017. According to DOE, this update will address the recommendation. When we confirm what actions DOE has taken in response to this recommendation, we will provide updated information.
    Recommendation: To ensure that DOE's long-term plans for storing waste in the existing SSTs and DSTs at Hanford consider the condition of the tanks and the WTP construction delay, the Secretary of Energy should assess the alternatives for creating new RCRA-compliant tank space for the waste from the SSTs, including building new DSTs.

    Agency: Department of Energy
    Status: Open

    Comments: As of December 6, 2016, DOE officials indicated that DOE intends to assess the feasibility of new DST construction as part of its update to the Hanford Site System Plan (to be released October 2017). According to DOE, several contingency actions will be included in the scenarios that will be analyzed including new DST construction. When we confirm what actions the agency has taken in response to this recommendation, we will provide updated information.

    Recommendation: The Administrator, EPA, should take a number of steps to further protect the American public from elevated lead levels in drinking water. Specifically, to improve EPA's ability to oversee implementation of the lead rule and assess compliance and enforcement activities, EPA should ensure that data on water systems' test results, corrective action milestones, and violations are current, accurate, and complete.

    Agency: Environmental Protection Agency
    Status: Open

    Comments: In June 2017, EPA reported to GAO that the agency had been working with states through face-to-face trainings and webinars on the reporting of milestone data. GAO will continue to monitor these efforts and reevaluate whether water systems' test results, corrective action milestones and violations are current, accurate and complete subsequent to the completion of the Compliance Monitoring Data Portal and the Safe Drinking Water Information System (SDWIS) Prime, described briefly below. However, until these new tools are complete, the status of this recommendation remains open. According to EPA, SDWIS Prime will be available for testing in September 2017 and for state use at the end of March 2018. In an earlier update to GAO in June 2016, EPA highlighted several of its efforts to improve data quality, noting that it had given greater scrutiny to such improvements due to recent concerns about elevated lead in drinking water. For example, its SDWIS regional coordinators review all SDWIS data submissions for accuracy and timeliness before approving submittals to the agency. In addition, EPA provides the Regions and the States with a data quality matrix report that gives metrics on the accuracy and timeliness of the last submission, after each quarterly submission. The agency has also focused on promoting electronic reporting of drinking water data through development of the Compliance Monitoring Data Portal, and is developing SDWIS Prime to improve state program efficiency, automate candidate violation notifications, increase data submission quality, and promote reporting of compliance monitoring data.
