The North Carolina Department of Environmental Quality wants more information on a proposed stone quarry in Alamance County.
Alamance Aggregates submitted a mining permit application to the state last year. The company wants to establish a quarry in Snow Camp near Duke Energy transmission lines and a major gas pipeline.
Last month, NCDEQ held a public hearing where residents spoke about health and environmental concerns regarding the possible crushed stone quarry.
NCDEQ is asking for various types of documentation and information, including:
- Proof that Alamance Aggregates properly notified the county manager and energy pipeline companies about the quarry;
- Proof that Duke Energy and Colonial Pipeline Company have no issue with the quarry’s location;
- The estimated life in mine years and a hydrogeological study for the proposed operation;
- A thorough investigation of the geology at the proposed mine site;
- Proof of an individual permit and an air quality permit that addresses the amount of free silica dust and radon that will be released into the air;
- Proof that there’s a valid approved wetland delineation for the site;
- Overburden calculations;
- A revised blasting vibration study;
- A well survey and responses to concerns from the North Carolina Wildlife Resources Commission and the Winston-Salem Regional Office regarding erosion and sediment control.
Alamance Aggregates has six months to respond.
