STOP THE BOX ELDER GRAVEL MINE

Our Mission

At Stop The Mine, we are dedicated to safeguarding our citizens, protecting the environment and advocating for sustainable future. Our mission is to ensure that mining activities do not compromise the health, safety. and future of our community.

Stop the mine, act now!

Location: Corner of 225th St & 151st St

The proposed gravel mine would sit on a parcel at the corner of 225th st and 151st.  As seen from the map on the left, the proposed site shares a border with two separate housing developments and is within 1/2 mile of 2 more housing tracts.  Additionally, Douglas Schools are .58 miles from the site and have two main school bus throughfares directly next to the site with a large amount of student foot traffic in the vicinity.

Property Value Impact

Such a development will cause a significant decrease in surrounding property values, estimated to plummet by 20% to 30%. For homeowners in Box Elder, this translates to a loss in our property investments – an alarming proposition for many families who have worked hard to establish a stable home and community. 


With a drop in property value comes a corresponding drop in property taxes.  This represents a tax revenue loss to both Pennington and Meade counties.  This significant shortfall will have to be made up elsewhere potentially leading to an increase in already exorbitantly high property taxes or cuts to critical infrastructure programs.

Health Safety Hazard

Environmental and health concerns are also at the forefront. The plant will generate air pollution likely including crystalline silica dust, an unavoidable byproduct of gravel mining, which can travel miles.  Risks related to increase in particulate matter could increase the risk of cancer and respiratory ailments. Additionally, the potential contamination of ground water, and contribute an unknown level of noise pollution. This prospect could lead to harmful health impacts on residents, especially children given the .58-mile proximity to schools, and the elderly while also displacing wildlife from their natural habitats. 

Increased Heavy-Hauler Traffic

 The heightened heavy truck traffic will add considerable strain on our already deteriorating roads, potentially increasing maintenance costs and noise disturbances in our quiet neighborhood.   These increased costs must be carefully weighed against the decreased residential tax revenue due to lower property values.

Crystalline Silica Dust

Crystalline Silica Dust - The leading cause of DEADLY silicosis

Respirable dust, though invisible to the naked eye, presents significant health risks. In particular, respirable silica dust—composed of fine crystalline silica particles—can cause severe conditions such as silicosis, lung cancer, and chronic obstructive pulmonary disease (COPD). To mitigate these risks, the Occupational Safety and Health Administration (OSHA) implemented stricter regulations on September 23, 2017, lowering the permissible exposure limit (PEL) for respirable silica dust on construction sites. However, these regulations primarily safeguard equipment operators and do not extend protections to nearby individuals or the general public. Due to the nature of respirable dust, bystanders may still be exposed to harmful levels beyond the immediate work area.

The size of dust particles plays a critical role in determining their potential health impact. Particles must be smaller than 200 microns to become airborne, and those under 10 microns are classified as “respirable.” These finer particles can bypass the body’s natural defenses and reach deep into the lungs, posing serious health threats.  Respirable crystalline silica consists of extremely fine particles—at least 100 times smaller than typical beach sand—generated during activities  such as gravel mining. Additionally, the distance these particles travel is influenced by their size and environmental factors such as wind speed—higher wind speeds can carry respirable dust farther from the source.

Silicosis is a progressive and incurable lung disease caused by inhaling respirable crystalline silica—fine particles released during activities such as cutting, grinding, or drilling materials like stone, concrete, and brick. It primarily affects workers in construction, mining, and manufacturing industries.

There are three forms of silicosis—chronic, accelerated, and acute—depending on the level and duration of exposure. Symptoms include persistent cough, shortness of breath, fatigue, chest pain, and in severe cases, respiratory failure.

Silicosis significantly increases the risk of other serious conditions, including lung cancer, chronic obstructive pulmonary disease (COPD), kidney disease, and tuberculosis.

While there is no cure, treatment focuses on symptom management, including medications, oxygen therapy, and in advanced cases, lung transplantation. Prevention through proper workplace controls and personal protective equipment is essential.

Particles must be smaller than 200 microns to become airborne, and those under 10 microns are classified as “respirable", for reference a grain of pollen is 15 microns. Respirable dust can bypass the body’s natural defense mechanisms and reach the lungs, posing significant health hazards. The distance a dust particle travels while airborne is largely determined by its size, with smaller particles remaining suspended longer. Additionally, wind speed influences dispersion; as wind velocity increases, respirable dust particles can travel greater distances.

Wind Speed - 3.1 mph

Distance Travelled - 2.2 miles


10 micron particles

Wind Speed - 3.1 mph

Distance from mining site to Douglas Schools: .52 miles


Average yearly windspeed in Box Elder SD: 8.4 mph
