Drain Disposal Restrictions for Chemicals


Disposal of chemicals into the sanitary sewer is regulated by federal and state laws and regulations, by the local East Bay Municipal Utility District (EBMUD) Wastewater Control Ordinance and by the EBMUD Wastewater Discharge Permit issued to the campus. These laws and regulations prohibit any drain disposal of hazardous wastes and limit the allowable wastewater concentration of a number of specific substances. The University of California, Berkeley (UC Berkeley) is committed to protection of the local community and the environment through strict compliance with these laws and regulations. Discharge of hazardous chemical wastes into the campus sanitary sewer system is prohibited by campus policy (Water Protection Policy).


If a chemical spill enters a sink or floor drain, immediately notify the Office of Environment, Health & Safety (510-642-3073) during business hours 8:00 am – 5:00 pm. After business hours, immediately notify the UC Police Department (510-642- 6760) and ask them to contact the EH&S off-hours emergency responder. EH&S will notify EBMUD of the discharge.
