Step-by-step explanation:
Yes, state or local laws governing refrigerant can be less strict than federal laws. When it comes to environmental regulations, there is often a complex relationship between federal, state, and local laws. While federal laws provide a baseline standard, states and localities have the authority to enact stricter regulations if they choose to do so. However, they cannot pass laws that are less strict than federal laws. An example of this is the regulation of refrigerants. The federal government sets standards for the use of certain refrigerants to protect the ozone layer, but states can choose to adopt even stricter regulations if they deem it necessary.
