Final answer:
The maximum quantity of hazardous material allowed to be stored is not specified and depends on the regulations set forth by bodies like the DOT and EPA, as well as specific local codes. Compliance with these regulations ensures that hazardous materials are stored safely and within permissible limits.
Step-by-step explanation:
Regulations from the United States Department of Transportation and the Environmental Protection Agency (EPA) provide guidelines on hazardous material storage limits. To answer this question accurately, one must reference these regulations and any applicable local codes.
For example, EPA regulations govern the maximum permissible molarity of certain hazardous chemicals in wastewater, such as hexavalent chromium, which is limited to 0.50 mg/L when discharged as potassium dichromate (K₂Cr₂O₇). Concentrations exceeding this limit would be in violation of the regulations, and thus cannot be stored in a manner that would allow their discharge above these levels.
Furthermore, OSHA has a list of Highly Hazardous Chemicals that include specific storage requirements to prevent accidents in the workplace, which also implies limits on quantities that can be stored based on facility size, containment measures, and other factors.
