SUPPLEMENTARY INFORMATION:
I. Background
A. Legal Authority
Section 103(h) of the Federal Mine Safety and Health Act of 1977 (Mine Act) as amended, 30 U.S.C. 813(h), authorizes the Mine Safety and Health Administration (MSHA) to collect information necessary to carry out its duty in protecting the safety and health of miners. Further, section 101(a) of the Mine Act, 30 U.S.C. 811(a), authorizes the Secretary of Labor (Secretary) to develop, promulgate, and revise, as may be appropriate, improved mandatory health or safety standards for the protection of life and prevention of injuries in coal, metal and nonmetal mines.
The Paperwork Reduction Act (PRA) governs paperwork burdens imposed by Federal agencies on the public for using identical questions to collect information from 10 or more persons. Paperwork burden is defined in 44 U.S.C. 3502(2) as time, effort, or financial resources expended to generate, maintain, or provide information to or for a Federal agency. Under 44 U.S.C. 3507, policies and procedures of information collection are established for controlling paperwork burdens imposed by Federal agencies on the public, including evaluating public comments.
B. Information Collection
To fulfill the statutory mandates to promote miners' health and safety, MSHA requires information under the information collection request (ICR) titled "Respirable Coal Mine Dust Sampling". The information collection is intended to ascertain coal mine dust levels and to ensure coal miners are not exposed to excessive levels of respirable coal mine dust.
Chronic excessive exposure to respirable coal mine dust causes lung diseases including coal workers' pneumoconiosis (CWP), emphysema, silicosis, and chronic bronchitis. These diseases, known collectively as "black lung," are debilitating and can result in severe disability and premature death. While considerable progress has been made in lowering dust levels over time, severe cases of black lung continue to be identified. Information from the federally funded Coal Workers' Health Surveillance Program administered by the National Institute for Occupational Safety and Health (NIOSH) indicates that black lung remains an occupational health risk among coal miners.
[top] MSHA's standards in 30 CFR parts 70 and 71 require each operator of
Additionally, MSHA's standards in 30 CFR part 90 require that for coal mine employees who have exercised the option described in section 30 CFR 90.3 (hereafter referred to as part 90 miners? 1 ), the mine operator must place them in a work area of the mine where the average concentration of respirable dust in the mine atmosphere is at or below 0.5 mg/m 3 .
Footnotes:
1 ?Under 30 CFR 90.3(a), any miner employed at a coal mine who has evidence of the development of pneumoconiosis, based on a chest X-ray or other medical examinations, must be afforded the option to work in an area of a mine where the average concentration of respirable dust in the mine atmosphere during each shift to which that miner is exposed is continuously maintained at or below the applicable standard. Each of these miners must be notified in writing of eligibility to exercise the option.
To ensure coal mine operators comply with the applicable dust standards specified in 30 CFR parts 70, 71, and 90, coal mine operators are required to sample respirable coal mine dust quarterly and submit these samples to MSHA for analysis.
Underground coal mine operators must take the following samples quarterly with an approved Continuous Personal Dust Monitor (CPDM) unless notified by MSHA that they may use an approved Coal Mine Dust Personal Sampling Unit (CMDPSU) to conduct sampling:
• The Designated Occupations (DO) and Other Designated Occupations (ODO) associated with each Mechanized Mining Unit (MMU), and
• Each Designated Area (DA) location specified in the operator's approved mine ventilation plan.
At surface coal mines and surface work areas of underground coal mines, operators must take quarterly samples of the Designated Work Positions (DWP) with an approved CMDPSU unless notified by MSHA that they may use an approved CPDM to conduct sampling.
Furthermore, at both surface and underground coal mines each part 90 miner may only be sampled with an approved CPDM unless notified by MSHA that they may use an approved CMDPSU.
This information collection request summarizes recordkeeping and reporting burden, and costs associated with respirable coal mine dust sampling, which includes six components:

2. CMDPSU Sampling
i. Collecting, Certifying, and Submitting CMDPSU Samples
After conducting quarterly sampling and notating irregular flowrate or other events, all mine operators using CMDPSUs must certify and submit these samples to MSHA.
Underground Coal Mines
Under 30 CFR 70.201(b)(2), DAs identified by the operator under section 75.371(t) must be sampled quarterly with an approved CMDPSU, unless the operator notifies the District Manager in writing that only an approved CPDM will be used for all DA sampling at the mine. The notification must be received at least 90 days before the beginning of the quarter in which CPDMs will be used to collect the DA samples.
Under 30 CFR 70.209(a), if using a CMDPSU, the operator must sample quarterly each DA on consecutive production shifts until five valid representative samples are taken.
Under 30 CFR 70.205(b)(2), if using a CMDPSU, each approved sampling device must be examined each shift by a person certified in sampling during the last hour of operation to assure that the sampling device is operating properly and at the proper flowrate. If the proper flow rate is not maintained, the respirable dust sample must be transmitted to MSHA with a notation by the certified person on the back of the dust data card stating that the proper flowrate was not maintained. Other events occurring during the collection of respirable dust samples that may affect the validity of the sample, such as dropping of the sampling head assembly onto the mine floor, must also be noted on the back of the dust data card.
Under 30 CFR 70.210(c), a person certified in sampling must properly complete the dust data card that is provided by the manufacturer for each filter cassette. The card must have an identification number identical to that on the cassette used to take the sample and be submitted to MSHA with the sample.

Surface Coal Mines and Surface Work Areas of Underground Coal Mines
Under 30 CFR 71.201(a), each operator must take representative samples of the concentration of respirable dust in the active workings of the mine only with an approved CMDPSU. The operator may use an approved CPDM if the operator notifies the District Manager in writing that only an approved CPDM will be used for all DWP sampling at the mine. The notification must be received at least 90 days before the beginning of the quarter in which CPDMs will be used to collect the DWP samples.
Under 30 CFR 71.206(a), if using a CMDPSU, each operator must take one valid representative sample from the DWP during each quarterly period.
Under 30 CFR 71.205(b)(2), if using a CMDPSU, each sampling device must be examined each shift by a person certified in sampling during the last hour of operation to assure that it is operating properly and at the proper flowrate. If the proper flowrate is not maintained, the respirable dust sample must be transmitted to MSHA with a notation by the certified person on the back of the dust data card stating that the proper flowrate was not maintained. Other events occurring during the collection of respirable dust samples that may affect the validity of the sample, such as dropping of the sampling head assembly onto the mine floor, must also be noted on the back of the dust data card.
Under 30 CFR 71.206(e), each DWP sample must be taken on a normal work shift. If a normal work shift is not achieved, the respirable dust sample must be transmitted to MSHA with a notation by the person certified in sampling on the back of the dust data card stating that the sample was not taken on a normal work shift. When a normal work shift is not achieved, the sample for that shift may be voided by MSHA. However, any sample, regardless of whether a normal work shift was achieved, that exceeds the applicable standard by at least 0.1 mg/m 3 must be used in the determination of the equivalent concentration for that occupation.
Under 30 CFR 71.207(c), a person certified in sampling must properly complete the dust data card that is provided by the manufacturer for each filter cassette. The card must have an identification number identical to that on the cassette used to take the sample and be submitted to MSHA with the sample. Each card must be signed by the certified person who actually performed the required examinations during the sampling shift and must include that person's MIIN. Respirable dust samples with data cards not properly completed may be voided by MSHA.
