2020-04583. Proposed Extension of Information Collection; Radiation Sampling and Exposure Records

AGENCY:

Mine Safety and Health Administration, Labor.

ACTION:

Request for public comments.

SUMMARY:

The Department of Labor, as part of its continuing effort to reduce paperwork and respondent burden, conducts a pre-clearance consultation program to provide the general public and Federal agencies with an opportunity to comment on proposed collections of information in accordance with the Paperwork Reduction Act of 1995. This program helps to ensure that requested data can be provided in the desired format, reporting burden (time and financial resources) is minimized, collection instruments are clearly understood, and the impact of collection requirements on respondents can be properly assessed. Currently, the Mine Safety and Health Administration (MSHA) is soliciting comments on the information collection for Radiation Sampling and Exposure Records.

DATES:

All comments must be received on or before May 5, 2020.

ADDRESSES:

You may submit comment as follows. Please note that late, untimely filed comments will not be considered.

Electronic Submissions: Submit electronic comments in the following way:

• Federal eRulemaking Portal: https://www.regulations.gov. Follow the instructions for submitting comments for docket number MSHA-2020-0006. Comments submitted electronically, including attachments, to https://www.regulations.gov will be posted to the docket, with no changes. Because your comment will be made public, you are responsible for ensuring that your comment does not include any confidential information that you or a third party may not wish to be posted, such as your or anyone else's Social Security number or confidential business information.
• If you want to submit a comment with confidential information that you do not wish to be made available to the public, submit the comment as a written/paper submission.

Written/Paper Submissions: Submit written/paper submissions in the following way:

• Mail/Hand Delivery: Mail or visit DOL-MSHA, Office of Standards, Regulations, and Variances, 201 12th Street South, Suite 4E401, Arlington, VA 22202-5452.
• MSHA will post your comment as well as any attachments, except for information submitted and marked as confidential, in the docket at https://www.regulations.gov.

SUPPLEMENTARY INFORMATION:

I. Background

Section 103(h) of the Federal Mine Safety and Health Act of 1977 (Mine Act), 30 U.S.C. 813(h), authorizes 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, authorizes the Secretary of Labor 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 and metal and nonmetal mines.

Under the authority of Section 103 of the Federal Mine Safety and Health Act of 1977, MSHA is required to issue regulations requiring operators to maintain accurate records of employee exposures to potentially toxic materials or harmful physical agents which are required to be monitored or measured under any applicable mandatory health or safety standard promulgated under this Act.

Airborne radon and radon daughters exist in every uranium mine and in several other underground mining commodities. Radon is radioactive gas. It diffuses into the underground mine atmosphere through the rock and the ground water. Radon decays in a series of steps into other radioactive elements, which are solids, called radon daughters. Radon and radon daughters are invisible and odorless. Decay of radon and its daughters results in emissions of alpha energy.

Medical doctors and scientists have associated high radon daughter exposures with lung cancer. The health hazard arises from breathing air contaminated with radon daughters which are in turn deposited in the lungs. The lung tissues are sensitive to alpha radioactivity.

The amounts of airborne radon daughters to which most miners can be exposed with no adverse effects have been established and are expressed as working levels (WL). The current MSHA standard is a maximum personal exposure of 4 working level months per year.

Excess lung cancer in uranium miners, just as coal workers' pneumoconiosis, silicosis, and other debilitating occupational diseases, has been recognized for many years. Thus, an adequate base of accurate exposure level data is essential to control miners' exposures and permit an evaluation of the effectiveness of existing regulations.

The standard at 30 CFR 57.5037 established the procedures to be used by the mine operator in sampling mine air for the presence and concentrations of radon daughters. Operators are required to conduct weekly sampling where concentrations of radon daughters exceed 0.3 WL. Sampling is required bi-weekly where uranium mines have readings of 0.1 WL to 0.3 WL and every 3 months in non-uranium underground mines where the readings are 0.1 WL to 0.3 WL. Mine operators are required to keep records of all mandatory samplings. Records must include the sample date, location, and results, and must be retained at the mine site or nearest mine office for at least 2 years.

The standard at 30 CFR 57.5040 requires mine operators to calculate and record individual exposures to radon daughters on MSHA Form 4000-9 “Record of Individual Exposure to Radon Daughters.” The calculations are based on the results of the weekly sampling required by 30 CFR 57.5037. Records must be maintained by the operator and submitted to MSHA annually.

II. Desired Focus of Comments

MSHA is soliciting comments concerning the proposed information collection related to Radiation Sampling and Exposure Records. MSHA is particularly interested in comments that:

• Evaluate whether the collection of information is necessary for the proper performance of the functions of the Agency, including whether the information has practical utility;
• Evaluate the accuracy of MSHA's estimate of the burden of the collection of information, including the validity of the methodology and assumptions used;
• Suggest methods to enhance the quality, utility, and clarity of the information to be collected; and
• Minimize the burden of the collection of information on those who are to respond, including through the use of appropriate automated, electronic, mechanical, or other technological collection techniques or other forms of information technology, e.g., permitting electronic submission of responses.

Background documents related to this information collection request are available at https://regulations.gov and in DOL-MSHA located at 201 12th Street South, Suite 4E401, Arlington, VA 22202-5452. Questions about the information collection requirements may be directed to the person listed in the FOR FURTHER INFORMATION section of this notice from the previous collection of information.
