Mines in New York


Owner Type

There are 1,952 active mines as shown on the following map. In 2014, industry operated 1,555 mines or almost 80% of the mines in New York State. Towns, villages and other small local government entities operated 353 mines, and 37 mines were county-owned and operated. New York State agencies operate seven mines. Most of the government mines are permitted to highway departments which use the material for road maintenance.

Trends in Mine Size and Number

Mine renewal and modification permits issued in 2014 ranged in life-of-mine acreage from 1 to 1,174 acres. However, new mines tend to be smaller; about 46.4% of new mines permitted in 2014 were 10 acres or less in size. The largest new mine was the 56.96-acre Suit-Kote Corp Alexander Mine in Cortland County.

The following tables give 2010-2014 size range information for all active mines, including detailed information on mined land and reclamation permits by county. While the number of mines has been decreasing over time, the rate of decline has been greater for mines under 10 acres in size than those greater than 10 acres. This was due to many operators expanding or combining existing mines rather than seeking permits for new sites combined with final reclamation of mines. This trend began to change, in 2009, when the required regulatory fees were increased for sites with greater than 20 acres affected by mining. However, since 2013 there is a slight increase in the total number of mines with more than 30 acres affected.

The minor projects in the first row of the below table are always less than 5 acres in size. They are subject to a simpler review process, but must comply with very strict criteria to be considered minor: minimum setbacks from homes and surface waters; a maximum 20-foot mine depth; no mining below water table; no hardrock (consolidated material) mining; and no on-site processing equipment, such as washing or crushing machines.
