South Dakota has significant gold and silver mining operations in the Black Hills (Barrick Gold’s Wharf Mine, Coeur Mining’s Wharf Mine, Homestake legacy at Lead), major military installations (Ellsworth AFB — home of the B-21 Raider and B-1B Lancer), substantial agriculture and meat processing, and a growing financial services and technology sector. South Dakota’s WC system is administered by the South Dakota Department of Labor and Regulation (DLR) under SDCL Title 62. Federal OSHA applies to most private employers; MSHA governs mining. This guide covers South Dakota’s WC framework for occupational hearing loss and the documentation strategy South Dakota employers need.

South Dakota high-noise industries
- Gold and silver mining — Black Hills (Barrick Wharf Mine near Lead/Deadwood, Coeur Wharf Mine); drill rigs, blasting, crushers, conveyors
- Military — Ellsworth AFB (28th Bomb Wing — B-1B Lancer and incoming B-21 Raider); aircraft operations, weapons systems
- Meat processing — Tyson Foods (Dakota City, NE nearby; SD operations), Smithfield Foods; processing lines, conveyor systems
- Agriculture — corn and soybean processing; grain elevator operations, dryers
- Construction — Sioux Falls, Rapid City metros; active infrastructure and commercial markets
OSHA requirements: what South Dakota employers must do
South Dakota does not have a state OSHA plan for private-sector employers. Federal OSHA standards apply directly, including 29 CFR 1910.95 for occupational noise. Mining operations in the Black Hills are under MSHA jurisdiction (30 CFR Part 56 for surface metal/nonmetal). South Dakota employers with workers exposed at or above 85 dBA TWA must implement a full hearing conservation program.
How occupational hearing loss claims work in South Dakota
South Dakota classifies occupational hearing loss as an occupational disease under SDCL Title 62. The DLR administers the WC system; contested claims are adjudicated by DLR hearing examiners. South Dakota’s 2-year SOL runs from the date of injury or manifestation of the occupational disease. For gradual NIHL, manifestation is typically when the worker became aware of significant hearing impairment attributable to employment. The audiometric record and noise monitoring documentation are the primary defense tools.
How South Dakota calculates hearing loss awards
South Dakota uses a scheduled loss system for permanent hearing impairment. The formula: percentage of binaural hearing impairment × scheduled maximum weeks for total hearing loss × compensation rate. The audiometric record is the primary document establishing the impairment percentage.
The future claims picture: what the research says
The Lancet Commission (2024) identified hearing loss as the single largest modifiable risk factor for dementia — a meta-analysis found a 37% increased risk of incident dementia attributable to hearing loss.
The ACHIEVE Trial (2023) found that hearing intervention slowed cognitive decline by 48% over three years in higher-risk adults.
For South Dakota employers: Black Hills mining workers and Ellsworth AFB contractors with decades of sustained noise exposure carry a hearing loss burden that won’t fully materialize in claims for another 10–30 years. The audiometric record built today is the defense available then.
Building a defensible hearing conservation program in South Dakota
Soundtrace provides South Dakota employers with OSHA-compliant in-house audiometric testing, automated STS detection, HPD fit testing, and digital record retention. For Black Hills mining and Ellsworth AFB contractor employers, complete audiometric records are the foundation of DLR defense and OSHA/MSHA compliance.
Frequently asked questions
2 years from the date of injury or manifestation of the occupational disease. For gradual NIHL, manifestation is typically when the worker became aware of significant hearing impairment attributable to employment.
Yes. Gold and silver mining operations in the Black Hills (including the Wharf Mine) are under MSHA jurisdiction (30 CFR Part 56 for surface metal/nonmetal mining) rather than OSHA. MSHA has its own noise monitoring, audiometric testing, and hearing protection requirements.
Build the program. Build the record.
Soundtrace gives South Dakota employers OSHA- and MSHA-compatible audiometric testing, automated STS tracking, HPD fit testing, and audit-ready records.
