Tom’s Creek is a small trout stream with headwaters in the Michaux State Forest, providing drinking water to the town of Fairfield, PA. Tom’s Creek is designated by the State as a High Quality stream. This high-quality stream is under a threat by a potential expansion of the Specialties Granules Incorporated (SGI) mining operation. SGI mines a green colored mineral called basalt, which is used as the surface material of shingles used in home construction. An expansion of the mining operation would discharge basalt stormwater into Tom’s Creek. The High-Quality designation has protections but does allow variances if there is an economic need.
