Six Utility Crossings from Landfill to Plant
DTD teamed with an environmental construction contractor to complete 6 bores at a mid-Atlantic industrial facility. The bores were part of the facility’s effort to improve management of the site’s industrial waste landfill through capping and running of new leachate collection lines.
The landfill is separated from the main plant by a public road, and rather than shut down the road for trenching for the pipeline installation, the utilities were installed using HDD. However, the facility has an impeccable safety record and requires the same of their subcontractors. Further, these construction activities were regulated by OSHA’s HAZWOPER Standard. This changed the installation from a relatively standard utility crossing, to one that allowed consideration of only a limited number of HDD contractors.
All DTD employees are OSHA 40-hour HAZWOPER trained, take part in the required refresher training, and undergo annual medical monitoring. These are standard requirements for most of our horizontal well installations, as are the completion of safety submittals (JSAs, HASP, etc., employee certs) and pre-qualification forms prior to mobilization. Since these requirements are SOP, it made it relatively easy for DTD to join the construction team and complete the work with a very short turn-around between contracting and project completion.
We mobilized one of our Vermeer 2440’s and a MCT-160 mud recycling system to complete the work. The mud recycling system was necessary due to the large diameter of the bores (16″) and the desire to minimize waste generation. The project was completed with 5 days of site activities and less than 30 days between the date of contract to the date of completion.
