We have informed Martin Marietta of the existence and function
of this web-site and made some requests of them in an open letter:
It is very important for the community to monitor mining
operations in the township. Dust from mining -- respirable crystalline silica
(RCS) -- is known to be a human carcinogen, based on sufficient evidence
of carcinogenicity from studies in humans. The link between human lung cancer
and exposure to RCS is strongest in studies of quarry and granite workers.
"Residents near quarries and sand and gravel operations are potentially
exposed to respirable crystalline silica" (
See National Toxicology Program - Report on Carcinogens - 9th
Edition ). This concern is magnified by the fact that Martin Marietta
has been fined by the
EPA for failing to control dust at their site in Highland County.
