MACS 609 Certification Practice Exam

Section 609 of the Clean Air Act is specifically designated for the regulation of mobile air conditioning systems and provides the Environmental Protection Agency (EPA) with the authority to establish standards related to the servicing of these systems. This provision was introduced to ensure that service practices do not harm the environment, particularly in terms of ozone-depleting substances and greenhouse gases.

By establishing proper guidelines and standards, Section 609 aims to mitigate the release of refrigerants that can pose serious environmental risks. It emphasizes technician certification and the use of approved equipment, which helps maintain the integrity of the atmosphere while ensuring that mobile A/C systems are serviced safely and effectively. The focus on both environmental protection and technician training highlights the importance of responsible servicing practices in the automotive industry.

The other sections mentioned do not specifically address mobile A/C servicing in the same manner, focusing instead on different aspects of air quality and pollution control. Therefore, the correct choice indicates the relevant authority and regulatory framework for mobile A/C servicing outlined in the Clean Air Act.
