The department’s Land Reclamation Program issues permits for mining industrial minerals. Amendments made in 1990 to the Land Reclamation Act (Missouri’s industrial minerals mining law) improved the requirements to be met for completing industrial mineral permit and reclamation processes. Industrial Minerals are gravel, limestone, granite, traprock, tar sands, clay, barite, sandstone, oil shale, sand, shale and other minerals defined by state statute. The two main types of industrial mineral mining include open pit mining and in-stream sand and gravel mining.
Many Missouri streams provide an abundant and easily accessible source of sand and gravel for construction activities. In-stream sand and gravel mining is one of the most prevalent types of commercial mining in Missouri, as far as the number of sites. However, in-stream sand and gravel mining is somewhat of a misnomer because this mining method does not allow for excavating machinery to mine in the flowing portion of the stream. This mining method would be more accurately described as a bar skimming mining operation.
Bar skimming is limited to the exposed portion of a gravel bar above the water line, within the ordinary high banks of a stream but not within the flowing water. Bar skimming is recommended as a means for advancing stream resource conservation while maintaining a viable extraction industry. This type of gravel removal operation lowers the risk of forward erosion of the stream channel upstream and sedimentation downstream from the area of excavation. In addition, the practice of removing gravel at periods of low water flow will aid in protecting water quality in the stream environment. Some of the rules include: staying an adequate distance from the stream bank, use of existing crossing areas, leaving an undisturbed buffer of 10 feet from the flowing water line and no mining below the water line. There are some circumstances when the operator can apply for and receive a variance after multi-agency consultations have occurred which generally involve the Missouri Department of Conservation and U.S. Army Corps of Engineers (Corps).
Improper removal of sand and gravel from streams can cause damage. The Missouri Department of Natural Resources is concerned that gravel removal be done properly to minimize impacts to landowners upstream and downstream. Other agencies, state and federal, have authority under existing regulations to help protect the health of streams.
In-Stream Sand and Gravel Permit Types
Commercial Gravel Mining
The department permits about 200 in-stream sites, annually. Numerous commercial mining operators across the state excavate sand and gravel deposits, commonly known as gravel bars, as a source of aggregate material.
The majority of commercial in-stream mining activities on gravel bars are permitted by the department, but there are some permitted by U.S. Army Corps of Engineers. The department and Corps worked together for the last 10 years to make their in-stream sand and gravel mining requirements nearly identical. If in-stream gravel removal is not conducted in strict compliance as permitted, the Corps and the department may become involved in additional permitting requirements.
Personal Gravel Mining
The department does not require a Commercial Gravel Mining permit for personal use only, as identified in the regulations at 10 CSR 40-10.010(2)(B)1. However, personal use gravel mining may be regulated by U.S Corps of Engineers under Section 404 of the Clean Water Act. Before conducting any stream gravel removal activities, contact Corps to determine what permitting requirements may apply to your proposed personal use gravel mining.
Length of Permit
Issued for one year. Can be renewed annually.
