The Rock Hill Quarry is large noncoal surface mine. The mineral actinolite, which can sometimes contain asbestos fibers has been found at the site. The Department has therefore required testing and investigations to determine if actual asbestos fibers are present within the rock being mined and in future mining areas. The initial and subsequent investigation and sampling did not identify asbestos. However, in December 2018, a rock sample tested positive for asbestos fibers. The Department, upon notice of the positive sample analysis, ceased all mining and crushing activities at the site, and they remain ceased at this time. The Department also required additional testing, sampling and investigation be undertaken at the site; and a plan outlining that proposed work will be submitted to the Department.
