• Frontier Stone must conduct ground water quantity monitoring and baseline water elevation data must be collected prior to the initiation of mining. 

  • Ground water monitoring will include the measuring of water levels monthly during the first two years of mining and quarterly thereafter. An annual report will be submitted to the DEC for the first five years of mining then once every permit term for the life of the project.

  • There will be no natural swales, channels or other constructed features that are capable to discharging waters to any off-site areas outside the limits of the mine, except those approved in the Mined Land Use Plan.


  • All silt laden water and stormwater generated on, or running across, the site shall be retained within the approved project area.

  • Frontier Stone must comply with all applicable State Pollutant Discharge Elimination System (SPDS) permit requirements and provide necessary notifications for off-site point discharges.

  • In conjunction with the United States Fish and Wildlife Service ( USFWS), Frontier Stone has agreed to establish an Alternative Mine Dewatering Discharge Location identified as "drainage basin 2" in a letter to the DEC dated November 11, 2015. The alternative discharge location will assist the USFWS in their wetland management efforts at the Iroquois National Wildlife Refuge (INWR). Frontier Stone will be able to redirect water upon written request of the USFWS "for a full period specified by the USFWS request." Use of the discharge location shall "be the minimum seasonally necessary to achieve proper mine dewatering, but at no time exceed a rate of 554,264 gallons per day."  The water discharged will "meet all effluent limits and requirements of Frontier Stone's coverage under the State Pollutant Discharge Elimination System (SPDES) Multi-Sector general Permit for Stormwater Discharges Associated with Industrial Activity." 

Residential Wells

If, after an initial assessment by the DEC, it is suspected that the mining operation may have impacted the quantity or quality of groundwater at and in the vicinity of the mine site, the Department may direct Frontier Stone to take any or all of the following steps to address the situation:

  • Frontier Stone must immediately supply water at its expense to the impacted property or properties, it must continue to supply water until it can be demonstrated to the satisfaction of the Department that the mining operation is not a contributing cause to the identified impacts.


  • If the impacted water supply is utilized as a drinking water source, potable water must be supplied.


  • If the mining operation has negatively impacted the water supply utilized as a drinking water source, Frontier Stone must connect the impacted property or properties to a municipal water supply system, if available. If a municipal water supply system is unavailable, a permanent potable water source must be supplied.
