EAC OIG, through the independent public accounting firm of Clifton Gunderson LLP, audited $84.9 million in funds received by the New Jersey Department of State under the Help America Vote Act. The objectives of the audit were to determine whether the Department of State (1) used payments authorized by Sections 101, 102, and 251 of HAVA in accordance with HAVA and applicable requirements; (2) used payments authorized by Sections 101, 102, and 251 of HAVA in accordance with HAVA and applicable requirements; and (3) met HAVA requirements for Section 251 funds for an election fund and for a matching contribution except for the requirements for maintenance of a base level of state outlays, commonly referred to as Maintenance of Expenditures (MOE).

TVA OIG retained Marshall Miller & Associates, Inc. (Marshall Miller) to conduct a peer review of the Stantec Consulting Services, Inc. (Stantec) report on geotechnical exploration and slope stability for the Ash Disposal Areas 2 and 3 at the Johnsonville Fossil Plant. Marshall Miller believes that Stantec's evaluations provide a reasonable assessment of the margin of safety associated with the evaluated conditions, which indicates that the facility is not in danger of imminent failure.In Marshall Miller's opinion, Stantec followed generally accepted practices and arrived at reasonable predictions of exit gradients. With regard to Stantec's development of material shear strengths, Marshall Miller found Stantec arrived at reasonable shear strength properties for the generalized material layers and zones. However, Marshall Miller believes the calculated factors of safety against piping in the heterogeneous fill are overstated because Stantec used high values of critical gradient for the fill relative to its measured in-situ densities. Based on review of Stantec's slope stability analyses, it is Marshall Miller's opinion that Stantec performed stability analyses for static, long-term load conditions using appropriate methodologies and reasonable material properties.

TVA OIG retained Marshall Miller & Associates, Inc. (Marshall Miller) to conduct a peer review of the Stantec Consulting Services, Inc. (Stantec) report on geotechnical exploration and slope stability for the gypsum stack at the Widows Creek Fossil Plant. Marshall Miller believes that Stantec's evaluations of the Widows Creek gypsum stack provide a reasonable assessment of the margin of safety associated with the evaluated conditions, which indicates that the facility is not in danger of imminent failure.Marshall Miller did find that additional analyses and corresponding documentation was needed in order to assess the overall factor of safety of the stack in the midterm and longterm. Marshall Miller also found that Stantec used a model that was 20 feet lower than the final height of the stack which does not reflect the final conditions of the pile. Additionally, Marshall Miller found that Stantec did not (1) perform adequate testing to support reliance on historical data and shear strength characterization of some materials, (2) calculate and document the exit gradient and factors of safety against piping for the 5-year build-out configuration, and (3) perform sufficient investigation of the clay foundation soils.To address this report, TVA management had Stantec review and respond to the findings of this report. Marshall Miller reviewed Stantec's response and concluded that the additional information provided adequately addressed the concerns and recommendations identified in the report.

TVA OIG retained Marshall Miller & Associates, Inc. (Marshall Miller) to conduct a peer review of the Stantec Consulting Services, Inc. (Stantec) documents for proposed improvements to the stability of the Northeast Dike of the Ash Disposal Area No. 2 of the Johnsonville Fossil Plant. Based on Marshall Miller's technical review, Stantec used generally accepted methods and practices to design the stability improvements. Based on the Stantec Calculation Package, Stantec also designed a slope configuration that provides acceptable factors of safety for slope stability under long-term, steady-state seepage conditions.Marshall Miller found the plans for construction prepared by Stantec provide suitable guidance for construction, however, they found the details of the graded filter portion of the stabilization berm do not conform closely with current standards of practice and present constructability issues at locations where the installation condition are more challenging.To address this report, TVA management had Stantec review and respond to the findings of this report. Marshall Miller reviewed Stantec's response and concluded that the additional information provided adequately addressed the concerns and recommendations identified in the report.
