MSHA rules for surface mining contractors

Under US federal law an independent contractor working at a mine is an operator in its own right: the Mine Safety and Health Administration (MSHA) can cite it for violations by it and its employees, and it must give the mine its details under 30 CFR Part 45 and, for most site work, hold an MSHA contractor ID. Its miners train under Part 46 at shell dredging, sand, gravel, surface stone, surface clay, colloidal phosphate and surface limestone mines, or under Part 48 at other surface mines, and they work to the surface standards in Part 56 (metal and nonmetal) or Part 77 (coal).

The rule text below is quoted from the eCFR, which showed Title 30 up to date as of 23 September 2026.

Who counts as an independent contractor

The Federal Mine Safety and Health Act of 1977 defines an operator as “any owner, lessee, or other person who operates, controls, or supervises a coal or other mine or any independent contractor performing services or construction at such mine” (30 U.S.C. 802(d)). That last clause is why a load and haul, drill and blast or plant hire contractor carries operator duties.

30 CFR 45.2(c) gives the working definition:

“Independent contractor means any person, partnership, corporation, subsidiary of a corporation, firm, association or other organization that contracts to perform services or construction at a mine”

The mine owner is the “production-operator”. A contractor that contracts for the production of a mineral is classified as a mine operator and gets a mine ID number (MSHA Program Policy Manual, Vol. III, read 25 Sep 2026).

The MSHA contractor ID

Part 45 makes the ID sound optional: “Any independent contractor may obtain a permanent MSHA identification number” (30 CFR 45.3(a)). The policy manual narrows that. Unless cited for a violation, a contractor must have an ID if it performs, or has a contract to perform, any of nine types of work at a mine:

1. Mine development, including shaft and slope sinking.
2. Construction or reconstruction of mine facilities, including preparation plants and mining equipment.
3. Demolition of mine facilities.
4. Construction of dams.
5. “Excavation or earthmoving activities involving mobile equipment”.
6. Equipment installation, such as crushers and mills.
7. “Equipment service or repair of equipment on mine property for a period exceeding five consecutive days at a particular mine”.
8. Material handling within mine property, including haulage of ore and refuse, “unless for the sole purpose of direct removal from or delivery to mine property”.
9. “Drilling and blasting.”

So a surface contractor running excavators, haul trucks or drills on site needs one, though not before bidding: a successful bidder whose contract covers any of the nine must get one. Each contractor gets one number for “any and all job sites” (policy manual, 41-1).

To apply, file Form 7000-52, Contractor ID Request, online or through your MSHA district office, with your trade name, addresses, telephone number and “The estimated annual hours worked on mine property by the independent contractor in the previous calendar year” (45.3(a)).

What you must give the mine

Section 45.4(a) requires each contractor to give the production-operator, in writing, its name, address and telephone number, a description of the work and where at the mine it will be done, its MSHA ID if it has one, and its address of record for service of citations. The mine keeps that register and shows it to inspectors on request (45.4(b)).

Keep the address of record current: service of citations and orders is complete on “mailing to the independent contractor’s address of record” (45.5).

Training: Part 46 or Part 48

The type of mine decides which training rule applies.

Part 48 subpart B says so directly: it “does not apply to training and retraining of miners at shell dredging, sand, gravel, surface stone, surface clay, colloidal phosphate, and surface limestone mines, which are covered under 30 CFR Part 46” (48.21).

Part 46 in brief

Under Part 46 a “miner” includes “independent contractors and employees of independent contractors who are engaged in mining operations”, and mining operations cover drilling, blasting, extraction, crushing, screening, equipment maintenance and repair “and associated haulage of materials within the mine” (46.2). The contractor’s duties are plain:

“Each independent contractor who employs a miner, as defined in § 46.2, at the mine has primary responsibility for complying with §§ 46.3 through 46.10 of this part, including providing new miner training, newly hired experienced miner training, new task training, and annual refresher training.” (46.12(b)(1))

The contractor must also tell the production-operator about hazards its own work creates (46.12(b)(2)); the production-operator has primary responsibility for site-specific hazard awareness training (46.12(a)(1)).

The main numbers:

• Written training plan (46.3). A plan is treated as approved if it contains the minimum information in 46.3(b), including the contractor’s name and “independent contractor identification number(s)”.
• New miners: “no less than 24 hours of training”, of which “no less than 4 hours” before work starts, first aid and self-rescue within 60 calendar days, and the balance within 90 calendar days (46.5).
• New task training “must be provided before the miner performs the new task” (46.7).
• Annual refresher: “no less than 8 hours”, no later than 12 months after the previous one (46.8).
• Site-specific hazard awareness for each mine, including drillers and blasters who move between mines for the same employer (46.11(c)).
• Records on MSHA Form 5000-23 or an equivalent form, carrying the statement “False certification is punishable under § 110(a) and (f) of the Federal Mine Safety and Health Act” (46.9).

Part 48 in brief

At other surface mines, 48.23(a) requires “an MSHA-approved plan”, new miners get “no less than 24 hours of training” with at least 8 hours before work duties (48.25(a)), refresher training is “a minimum of 8 hours” a year (48.28(a)), and most courses “shall be conducted by MSHA approved instructors” (48.23(g)). MSHA’s policy manual says contractors “are not required to have an approved training plan under Part 48”, but their people must be trained under one, either the mine’s or their own.

Safety standards on a surface site

Part 56 “sets forth mandatory safety and health standards for each surface metal or nonmetal mine, including open pit mines” (56.1). Part 77 covers “bituminous, anthracite, and lignite surface coal mines” (77.1). A contractor works to the Part for the mine it is on.

For mobile plant, 56.14100(a) is the pre-shift rule: “Self-propelled mobile equipment to be used during a shift shall be inspected by the equipment operator before being placed in operation on that shift.” Defects that make operation hazardous take the machine out of service, tagged or parked in a posted area, until corrected (56.14100(c)). Our guide to pre-start checks covers what makes those checks useful.

Workplace examinations

At metal and nonmetal mines, 56.18002(a) reads:

“A competent person designated by the operator shall examine each working place at least once each shift before miners begin work in that place, for conditions that may adversely affect safety or health.”

The record must be made “before the end of the shift”, and must contain “the name of the person conducting the examination; date of the examination; location of all areas examined; and description of each condition found that may adversely affect the safety or health of miners” (56.18002(b)). When a condition is corrected, the record must show “the date of the corrective action” (56.18002(c)). Records are kept “for at least one year” (56.18002(d)).

Because a contractor is an operator under the Act, agree in writing with the mine who examines which areas and where the record lives.

At surface coal mines, 77.1713(a) requires an examination each shift “by a certified person designated by the operator”.

Citations: who is cited

MSHA’s stated policy is “to issue citations and, where appropriate, orders to independent contractors for violations of applicable provisions of the Act, standards or regulations”, and “Inspectors should cite independent contractors for violations committed by the contractor or by its employees” (policy manual, 45-1).

The mine operator can be cited as well. The manual calls this “overlapping” responsibility and says citing the production-operator is normally appropriate when it contributed to the violation or to its continuing, when its own miners are exposed, or “when the production-operator has control over the condition that needs abatement”.

For Part 48 training, the policy manual says an untrained miner draws a section 104(g) withdrawal order against “the direct employer”. If the inspector cannot tell who employs the person, the order goes to the production-operator.

A regular assessment is capped at “not more than $90,649” per violation (30 CFR 100.3(a), as current on 23 September 2026). For contractors, size is “measured by the total hours worked at all mines” and violation history counts violations “at all mines” (100.3(b) and (c)), so one poor site affects penalties everywhere you work.

Common questions

Does an independent contractor need an MSHA contractor ID?

Any contractor may get one, and MSHA’s policy manual says contractors doing any of nine kinds of work at a mine must have one, including earthmoving with mobile equipment, haulage within mine property, drilling and blasting, and equipment repair lasting more than five consecutive days. Apply on Form 7000-52.

Is Part 46 or Part 48 training required for contractors?

Part 46 applies at shell dredging, sand, gravel, surface stone, surface clay, colloidal phosphate and surface limestone mines. Part 48 subpart B applies at other surface mines and surface areas of underground mines. The type of mine decides which one applies.

Who gets cited when a contractor breaks an MSHA standard?

MSHA’s policy is to cite the independent contractor for violations committed by the contractor or its employees. It may also cite the mine operator, for example where the operator contributed to the violation, its own miners were exposed, or it controls the condition.

How many hours of training does a new miner need under Part 46?

At least 24 hours: no less than 4 hours before starting work, the rest within 90 calendar days, then at least 8 hours of annual refresher training every 12 months.
