DEQ Approves YC Pond Repair Plan

Repair Plan Approval: The MDEQ provided a few more comments on the repair plans, which we incorporated and resubmitted on March 16, 2016.  The MDEQ delivered a copy of its letter approving the repair plans on March 17, 2016.  The MDEQ will be visiting the site during the construction to repair the pond, and continues to be very responsive and collaborative through this process.

Current Construction: Williams Civil continues to work on grouting the annuls of the casement pipe. Over the past 48 hours, we have focused on continued cleanup operations, material preparation and the initial assembly of repair pieces. Although winter storms have hit the site intermittently, we mitigated the weather with tents and heating equipment, and have avoided interrupting the work.

Testing: The MDEQ has released the first round of testing data from the initial leak. The Gallatin River Task Force, Confluence Engineering and YC continue to gather data. Once the requisite data sets have been received, Gallatin River Task Force will publish them, and we will provide a link to those results.
