Site had a blowout that released sediment to a wetland. During the inspection NCDEQ was informed that it was reported to Division of Water Resources, however no communications were given to show this. Concrete washout pits SHOULD BE LINED. The goal of the washout is to protect not only surface water but groundwater as well and without a liner infiltration can occur. Onsite fuel tanks were in a hazardous area where they could be subject to collision with vehicles, they should be inspected frequently to ensure they were not damaged and leaking.
