TSF Sample Clauses
TSF. Routine surveillance of the TSF ensures that maintenance and radiological controls that govern access to and placement, storage, and transfer of contaminated material in the TSF are current and effective. Surveillance this quarter (see surveillance checklists in Appendix A) revealed that: • The TSF cover, fencing, radiological controls, and signs have been maintained in accordance with the LTS&M Plan, and the TSF has been inspected and verified as ready to receive contaminated materials. LM is required to initiate the transfer of TSF materials for permanent disposal at the Grand Junction, Colorado, Disposal Site when the contents reach a volume of approximately 75 cubic yards. Recent TSF activity consists of the following: • Approximately 6 cubic yards of soil excavated from the city streets is stored in the TSF
TSF. This work involved a procedure similar to that described in the New Mexico Department of Agriculture Dam Breach Analysis reports above, except that tailings were considered in the breach analysis. The program DAMBRK was used to estimate the mud-flow characteristics of the breach, and the sediment transport capabilities of FLO2D were used to route the breach downstream. Helped with the geophysical investigation for Glade Reservoir. This work consisted of several electrical resistivity surveys and MASW surveys to look for faults in the bedrock below the proposed dam location. Provided PM support for the Morphy Dam Rehabilitation Project, specifically with budget tracking, scheduling, document organization and meeting preparation. ▇▇▇▇ was involved with reviewing and responding to RFI’s, QC tracking, and development of the monthly construction reports as well as the construction completion report. Provided H&H support for the design of the 2 WRP re- grades, namely Capulin WRP and Goat Hill North WRP. The H&H work involved developing the site hydrology with a highly detailed HEC-HMS model, as well as performing several channel and culvert design calculations and an erosion/scour analysis. Developed a two-dimensional HEC-RAS model to simulate several dam breach scenarios and route the outflows downstream. General and Hydrology hazard classifications were determined in accordance with CO rules and regulations by comparing the incremental lives lost associated with a breach vs. no- breach scenario, for both the sunny day and PMF event. ▇▇▇▇ also developed an outlet works rating curve for ▇▇▇▇▇▇▇▇ Dam based on information obtained from the record drawings and a tail water rating curve. Assisted in the development of a design for the principal and auxiliary spillways for Dam 101 near Austin, TX. The principal spillway consisted of a steel outlet works conduit, an intake structure with a trash rack, and a USBR Type VI impact basin. The auxiliary spillway consisted of a labyrinth ▇▇▇▇ and a USBR Type III stilling basin. Both spillways were designed to pass the PMF event using USACE and USBR design guidelines. In addition to the design calculations, ▇▇▇▇ assisted in developing the design drawings and construction specifications for the final design report. Developed a rain-on-grid HEC-RAS model to determine whether or not the ▇▇▇▇▇▇▇▇▇ Tailings Impoundment has the capacity to store the runoff associated with a PMF event. Also performed analyses to determine the runoff...

This is further refined to 2.9% of the area on p119. By comparison Table 4.12 indicates that the patches < 100 ha account for 6.5% of the area. This difference is likely due to the choice of the mid point value and the fact the observation data is not arranged equally on either side of the mid point. The difference is small and likely not significant in assessing the trend in patch size. The percentage value for the class size < 50 ha in both Tables 4.12 and 4.14 would be more accurately represented as 2-3%.
