Hot mix asphalt and truck mix concrete batch plant
- In January 2021, the Caswell County Planning Department processed and approved four permits for the company’s proposed projects – two for the Burlington North (Anderson) site and two for the Prospect Hill Quarry and Distribution Center (Quarry) site. They are Watershed Protection Permits and Special Non-residential Intensity Allocation (SNIA) Permits.
- In February 2021, many residents and landowners affected by the permit decision filed an appeal with the county planning department in accordance with local ordinance.
- In May 2021, the company sued 55 of the permit appellants in Superior Court to settle the question of vested rights in court. The company later added three additional defendants to the lawsuit. See the NC Policy Watch article by Lisa Sorg “Tired of fighting opponents of a proposed mine and asphalt plants, Carolina Sunrock decides to sue“
- In March 2022, the Superior Court judge dismissed the lawsuit against the 3 defendants that were added. See the NC Policy Watch article by Lisa Sorg “Caswell County judge dismisses mining company lawsuit against residents, citing free speech“
- The appeal hearing of the local permits has been postponed by the county multiple times and will probably continued to be postponed until the outcome of the Superior Court case.
- No trial court date has been set for the lawsuit in Superior Court
- NC DEQ/DMLR issued a mining permit to the company on 12/13/2021. An appeal has been filed with the NC Office of Administrative Hearings (OAH).
- NC DEQ/DAQ issued the company an air quality permit for the Prospect Hill Quarry and Distribution Center on 10/19/2021.
