When must the holder of a mine opening permit apply for an extension?

The correct timeframe for the holder of a mine opening permit to apply for an extension is within thirty days after January first each year. This requirement is designed to ensure that all necessary permits are kept current and that mining operations can proceed without interruption. By mandating this time frame, regulatory bodies can monitor and enforce compliance with safety standards and operational regulations throughout the mining industry.

This schedule supports effective oversight and guarantees that permit holders are regularly assessing their operations in light of any changes in regulations or safety requirements that may arise from year to year. Timely applications for extensions allow for a proactive approach to maintaining safety and operational readiness in mining.

Other options may suggest timelines that either do not align with regulatory requirements or provide more rigid structures than necessary for maintaining compliance.
