The day following this discovery, Henderson placed <br /> small dams within the ultimate canal structure, which is currently running at yearly low <br /> flow pace. Once the water flow was terminated to this section, the area adjacent to the <br /> leak was excavated Two days following the initial discovery, the pipeline was fitted with <br /> a block form, commonly used for the same application with industrial piping. On <br /> September 29, 2017, Henderson poured a large concrete anchor block around the flange <br /> and leaking section, which will eliminate future leaks from this section of the piping. The <br /> pipeline was stripped of forms and buried following a four day cure time on October 3, <br /> 2017. <br /> If you have any additional questions or concerns, please feel free to contact me at 720-942-3518 or <br /> Miguel Hamarat at 720-942-3255. <br /> Sincerely, <br /> Chief Environmental Scientist <br /> Climax Molybdenum Company <br /> Henderson Operations <br /> CC (via email): <br /> M.
