You're conflating two entirely different groups of people working for two different governments with entirely different motivations. It is entirely possible that the cops in the situation you observed didn't have any issue because they didn't think they were breaking any law they enforce. Your local police and EPA Special Agents have different jobs.

The Clean Air Act is a federal law. There are 10 states with laws directly targeting "rolling coal".
