NYCO expansion eyed at Seventy Road and Oak Hill mines

Willsboro-based firm asks APA OK for added hours, truckloads


---- — NYCO Minerals wants to expand mining and hauling from mines at Seventy Road and Oak Hill.

The two properties are separate from the Lot 8 test mines approved in a land-swap constitutional amendment last November.

Changes requested by the Willsboro-based mining company were announced recently in the Environmental News Bulletin.

At Seventy Road in the Town of Lewis, NYCO wants to add 14.9 acres of excavation, increasing the mine’s size to 69 acres.

It also wants to up the "life of mine" (available) acreage to 132.4 acres, adding 3.2 years for potential wollastonite excavation at the site.

The Adirondack Park Agency will hold a public information session on the request at 1:30 p.m. Wednesday, July 2, at the Lewis Fire Station.

Comments will become part of the public record on the mining expansion request. 


The expansion involves “relocation of 1,290 feet of (an) unnamed tributary of Derby Brook with two permanent stream crossings.”

In its environmental review, NYCO said: “The stream impacts will be mitigated by the creation of 1,410 feet of stream, increasing the overall length by 120 feet.”

The mining company would add a culvert on Patterson Creek.

“The project would impact 1.06 acres of federal wetlands mitigated by the creation of 2.2 acres of wetlands.”


NYCO is looking to add an hour of mining operations, currently conducted between 7:30 a.m. and 5:30 p.m. Monday through Friday, to 7 a.m. to 6 p.m. Monday through Friday.

At the end of excavation, NYCO said, “the mine will be reclaimed to grassland within two years of the cessation of mining."


NYCO is also looking to increase truck traffic to allow 100 loads of ore or rock aggregate daily from April 1 to Nov. 30 at the Oak Hill site.

It would essentially double the 45 loads currently allowed between July 1 and Aug. 31 and add about 30 percent more truckloads during the rest of mining season.

NYCO wants to amend its Oak Hill hauling permit to also allow up to “150 truck loads of aggregate (cap rock) to be trucked to Graymont Materials approximately 1.2 miles north of the mine on NY Route 9.”


The changes are not related to NYCO’s test-mining permit on Lot 8.

The APA approved the Temporary Revocable Permit, administrated by the State Department of Environmental Conservation, to allow test mining in phases at that site in Lewis. 

Mining tests on state land there were approved in a statewide constitutional amendment last November. If sufficient wollastonite ore is found, NYCO will swap 1,500 acres of land for the 200-acre Lot 8 parcel adjoining its property in Lewis.
