Proposed Extension of Information Collection: Sealing of Abandoned Areas

Published Date: 7/27/2026

Notice

Summary

The Department of Labor (DOL), as part of its continuing effort to reduce paperwork and respondent burden, conducts a pre- clearance consultation program for all information collections, to provide the 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. The Mine Safety and Health Administration (MSHA) is soliciting comments on the information collection titled "Sealing of Abandoned Areas."

Analyzed Economic Effects

7 provisions identified: 0 benefits, 6 costs, 1 mixed.

Annual paperwork and cost burden on mines

MSHA’s information collection on sealing abandoned areas covers 142 annual respondents and requires 37,871 responses per year. MSHA estimates the total annual time burden is 3,909 hours and annual recordkeeping costs of $670,609.

Daily atmosphere sampling requirement

Certified persons must sample each sampling pipe and approved sampling location at least every 24 hours and record oxygen and methane percentages. Sampling records must be retained at the mine for at least 1 year.

Gas thresholds can trigger miner withdrawals

If a sample from a sealed atmosphere (for seals under 120 psi) shows oxygen of 10 percent or greater and methane between 4.5 percent and 17 percent, the operator must take another sample and immediately notify the District Manager; if confirmed, persons must be withdrawn from the affected area. Operators may request approved exemptions in the ventilation plan.

Professional engineer certification for seal designs

Seal design applications must include engineering design information or full-scale test data and be certified by a professional engineer that the design meets current, prudent engineering practices. Applicants must notify MSHA of deficiencies and receive written approval or denial.

Training and certification retention rules

Certified persons who conduct sampling must be trained before sampling and annually thereafter, and operators must certify and retain each training certification for 2 years. Miners and senior officials who construct or repair seals must be trained before work and annually, with certifications retained for 2 years.

Timing rules for seal construction notices

Mine operators must notify the District Manager between 2 and 14 days before starting seal construction, notify in writing within 5 days after completion of a set of seals, and submit quality control results within 30 days of completion of tests.

Welding restrictions near seals

Welding, cutting, or soldering with an arc or flame is prohibited within 150 feet of a seal unless the operator requests and the District Manager approves a different location with continuous monitoring and safety procedures.
