Tiller begins prep work at Zavoral mine

Tiller Corporation expected to begin initial site work on the Zavoral mining and reclamation project in Scandia this week. Mining of gravel and reclamation will take place on 64 of the 114 acres at the site near the intersection of state highways 97 and 95.

Initial prep work due to begin includes installation of best management practices to control and manage stormwater and ensure water quality in the area, initial vegetation transplanting and removal, and preliminary grading for the first phase of reclamation.

The project has undergone extensive environmental review and will be regulated by several local, state and federal agencies. The majority of the site has been previously mined and left un-reclaimed, which has led to much of the site being overrun with non-native, invasive species and irregular landforms.

Under the terms of an agreement approved this year by the city of Scandia, Tiller will undertake a three-phase, 40-month mining project that will remove up to 1.2 million tons of gravel. The majority of the material will be transported to a nearby facility in Scandia for processing. Some of the material will then be used in local construction projects.

Tiller will conclude the project with significant reclamation of the site, including the establishment of dry prairie, mesic prairie and coniferous woodland communities. Such diversity of habitats does not exist at the site today.

Minnesota-based Tiller Corporation operates approximately 25 mining and processing sites in the region and employs nearly 250 people.
