Which statement is true regarding small quantities of hazardous materials and regulations?

Small quantities of hazardous materials may indeed be exempt from certain government reporting requirements, depending on the specific regulations and quantities involved. Various regulations, such as the Emergency Planning and Community Right-to-Know Act (EPCRA) and others, often outline thresholds for reporting hazardous substances. If the quantity of hazardous material falls below these thresholds, the entity handling the materials may not be required to report them to regulatory agencies, which helps streamline the regulatory burden on smaller operations while still ensuring safety and oversight to a degree.

While there can be local laws that apply to hazardous materials, these laws must also align with state and federal regulations. Therefore, saying that small quantities are "only regulated under local laws" does not accurately reflect the broader regulatory framework. Small quantities do not automatically exempt an entity from all regulations, nor are they necessarily subject to stricter federal guidelines; rather, they may simply be subject to different or less stringent regulatory requirements, depending on the total amounts handled.
