Special Waste

Due to their delicate nature, inherent instability or extreme toxicity, special waste cannot be disposed of using normal procedures.  Common waste streams that fall into this category include:

• Explosives
• Shock sensitive and peroxide forming chemicals
• Polychlorinated biphenyls
• Dioxins
• Department of Transportation Forbidden Materials

The following criteria must be met prior to disposing any wastewater into the sanitary sewer system:

• All wastes must comply with the limits established in the Ann Arbor Sewer Use Ordinance
• Liquids Only
• No RCRA hazardous wastes
• No Michigan hazardous wastes or Liquid Industrial By-Products
• No radioactive wastes
• No untreated biohazardous wastes

Please see the EHS Environmental webpage on Sanitary Drain Disposal for more information about sanitary discharge limitations.
