The Buna Quarry is not active and had no activity occuring. The site is being monitored and maintained. On a previous inspection I had suggested that Unimin request an additional inspection of the site and request dormant status to discontinue stormwater monitoring. Their mining permit is current and they are in compliance with DLR. We discussed that the annual stormwater permit fees will still need to be paid, and if at any time the mine wants to start back up a request would need to be submitted to return to active status. I suggested to Jeff that he submit his request in writing. We received the request on March 21, 2016. I recommend granting dormant status for the quarry.
