The San Diego Union-Tribune features a story on the tough decisions over curbing diesel pollution from heavy equipment.
The state Air Resources Board is planning new emission standards for heavy equipment. A recent hearing drew a large crowd and representatives from both sides of the issue.
Environmentalists and health professionals argue that new pollution standards should be enacted quickly to protect public health.
Construction companies, and other businesses that use heavy equipment, fear the costs of strict pollution laws could ruin their business. In order to comply, the businesses say that they need more time prepare their equipment.
To clean up equipment pollution, businesses will need to install new filters and engines, or upgrade older equipment to newer, cleaner models.
