Musk's boring company faces scrutiny and fines.

The Nevada regulatory agency revoked the Occupational Safety and Health Administration (OSHA) subpoena against Elon Musk's underground tunnel system company - The Boring Company, after intervention from the governor's office. However, the company was fined nearly $500,000 for illegal discharge of drilling mud in Las Vegas, marking a continued strengthening of regulatory oversight on the tunnel project by relevant authorities.
