MAC provided cultural resource compliance services for a windfarm containing 135 wind turbines located in Aurora, Brule, and Jerauld counties, South Dakota. A total of 85 sites were encountered on the project and the vast majority of them were avoided by construction. The sites that could not be avoided were recorded to ensure that all of the necessary legal requirements were met. Additionally, MAC provided Native American tribal consulting services on the project, in an attempt to protect important cultural properties.

MAC provided cultural compliance services for the construction of pipeline facilities covering more than 100 acres in Ward County, North Dakota. Only 1 site, a historic railroad line, was found during the project and the project was able to avoid any damage to it. An important cemetery was also found just outside the area and we recommended steps to retain the historic feel of the site.

MAC provided cultural compliance services for the portions of the Keystone pipeline project located in North and South Dakota. The project went through several stages lasting a number of years, and MAC ensured that cultural compliance requirements were met. Numerous sites were found, but they were all either avoided or properly recorded prior to disturbance. We also provided construction monitoring services on portions of the project that were likely to encounter buried cultural materials.
