Phase 1 Inspection Report: National Dam Safety Program. Mississippi - Kaskaskia - St. Louis Basin. Little Indian Creek Dam, Washington County, Missouri

This report presents the results of field inspection and evaluation of the Little Indian Creek Dam (MO 30718). It was prepared under the National Program of Inspection of Non-Federal Dams. This dam has been classified as unsafe, non-emergency by the St. Louis District as a result of the application of the following criteria: a. This dam retains less than 50 percent of the Probable Maximum Flood without overtopping the embankment. b. Overtopping of the embankment could result in failure of the dam. c. Dam failure significantly increases the hazard to loss of life downstream

Phase 1 Inspection Report: National Dam Safety Program. Mississippi - Kaskaskia - St. Louis Basin. Lac Marseilles Dam, St. Francois County, Missouri

This report presents the results of field inspection and evaluation of the Lac Marseilles Dam. It was prepared under the National Program of Inspection of Non-Federal Dams

Phase 1 Inspection Report: National Dam Safety Program. Mississippi - Kaskaskia - St. Louis Basin. Ditch Creek Dam, Washington County, Missouri

This report presents the results of field inspection and evaluation of Ditch Creek Dam. It was prepared under the National Program of Inspection of Non-Federal Dams. The inspection results indicate problems with the spillway adequacy. Although the dam is capable of passing the PMF without overtopping, the lack of a proper spillway and discharge channel and the need to pass runoff over a public transportation route (State Highway H) indicates a deficiency at this facility

Phase 1 Inspection Report: National Dam Safety Program. Mississippi -St. Francis Basin. Nims Lake Dam, Washington County, Missouri

This report presents the results of field inspection and evaluation of Nims Lake Dam, Missouri Inventory Number 30064. It was prepared under the National Program of Inspection of Non-Federal Dams. This dam has been classified as unsafe, non-emergency by the St. Louis District as a result of the application of the following criteria: a. Spillway will not pass 50 percent of the Probable Maximum Flood without overtopping the dam. b. Overtopping of the dam could result in failure of the dam. c. Dam failure significantly increases the hazard to loss of life downstream

Phase 1 Inspection Report: National Dam Safety Program. White River Basin. Ozark Lead Tailings Dam, Reynolds County, Missouri

This report presents the results of field inspection and evaluation of the Ozark Lead Tailings Dam. It was prepared under the National Program of Inspection of Non-Federal Dams

Pollutant Loadings and Impacts from Highway Stormwater Runoff. Volume III: Analytical Investigation and Research Report

DTFH61-84-C-00120This is one of four final documents of an investigation dealing with the characterization of stormwater runoff pollutant loads from highways, and the prediction of water quality impacts they cause. Study results are based on monitoring data from 993 individual storm events at 31 highway runoff sites in 11 States. Impact prediction is based on a methodology previously developed and applied to urban runoff and adapted for highway runoff applications. This document describes the procedures used to assemble and analyze the data base and reports the results of these analyses. Included in this document are statistical summaries of the data base, along with a description of procedures to use to predict pollutant discharges from highway sites and the impacts that they will cause to receiving waters

Pollutant Loadings and Impacts from Highway Stormwater Runoff Volume I: Design Procedure

DTFH61-84-C -00120This is one of four final documents of an investigation dealing with the characterization of stormwater runoff pollutant loads from highways, and the prediction of water quality impacts they cause. Study results are based on monitoring data from 993 individual storm events at 31 highway runoff sites in 11 States. Impact prediction is based on a methodology previously developed and applied to urban runoff and adapted for highway runoff applications. This document provides a step-by-step procedure for computing the estimated impacts on water quality of a stream or lake that receives highway runoff. Guidance is provided for evaluating whether or not a water quality problem will result, and the degree of pollution control required to mitigate impacts to acceptable levels

Pollutant Loadings and Impacts from Highway Stormwater Runoff Volume II: Users Guide for Interactive Computer Implementation of Design Procedure

DTFH61-84-C-00120This is one of four final documents of an investigation dealing with the characterization of stormwater runoff pollutant loads from highways and the prediction of water quality impacts they cause. Study results are based on monitoring data from 993 individual storm events at 31 highway runoff sites in 11 States. Impact prediction is based on a methodology previously developed and applied to urban runoff and adapted for highway runoff applications. This document is a users guide for an interactive computer procedure for computing the estimated impacts on water quality of a stream or lake that receives highway runoff. The program provides guidance for evaluating whether or not a water quality problem will result, and the degree of pollution control required to mitigate predicted impacts to acceptable levels. The computer program is based on the methodology presented in the Design Procedures report of this study

Deep borehole disposal of nuclear waste: US perspective

Radioactive waste disposal in deep boreholes may be more "ready" than disposal in mined geologic repositories since mankind has greater experience operating small deep holes - boreholes, than big shallow holes - mines. There are several thousand precedents for constructing >2 km deep boreholes and several hundred precedents for disposing long-lived wastes in boreholes. Borehole disposal is likely to be faster, cheaper, and more flexible than mined disposal, while also offering greater long-term isolation. Isolation would rely on the great depth, water density gradients, and reducing conditions to prevent vertical movement of waste up the borehole.Comment: 24 pages, 8 figure
