Sewer Disposal Approval Guidelines

Transcription

1 Sewer Disposal Approval Guidelines Introduction In order to prevent violations of local, state and federal regulations, all materials generated during a research or teaching process must be approved for drain disposal. The steps below ensure that no disposal of hazardous materials in violation of the Resource Conservation and Recovery Act (RCRA) or pollutants in violation of the Clean Water Act (CWA) enter the Washington University (WU) sewer system. In addition, WU Environmental Health & Safety (EHS) is obligated to evaluate the potential for harm to the Campus population and community health and to further address any potential dangers to the environment. Waste Stream Approval Process Limited approvals may be obtained for the waste generated from certain processes for research and teaching projects by contacting the EHS Environmental Compliance Division (ECD). Contact the Environmental Compliance Manager (Danforth: , Medical School: ) or have your laboratory Biological Chemical & Safety Division auditor facilitate the approval through the ECD. In order to obtain approval, please provide the following information: Identify the waste stream. Submit written methodology for the generation of the waste stream. Identify the constituents present in the waste stream including the concentration of all of the constituents. Consider any end products and intermediaries that might be present in the solution. Provide SDSs as appropriate. Provide analytical data as appropriate. Include flashpoint, ph or other physical properties. Identify the quantity generated in the process as well as the frequency of anticipated disposal. Identify any additional waste streams that would be potentially sewered at the same time.

2 Additional information may be requested in order to make the determination that the drain disposal of the waste stream will not violate regulatory constraints or affect the St. Louis Metropolitan Sewer District (MSD) operations or negatively impact receiving stream users. If approval is obtained from the EHS ECD, the approval must be included with the methodology in the respective laboratory Blue Book. Additionally, laboratory specific training must include a discussion of this approval and any restrictions included in the approval. Annually, all sewer disposal approvals must be recertified. This will be checked as part of your lab audit. If your lab moves or closes, EHSECD must be notified. Contact the Environmental Compliance Manager (Danforth: , Medical School: ) Non-Sewer Chemical Disposal Until a determination is made approving a waste stream for sewer disposal, chemicals and waste products must be disposed of through our on-line submittal system located at the EH&S web-site ( For disposal of surplus chemicals in their original containers and packaging, please follow guidelines for Laboratory Clean Outs, follow the Resources link at %20CLEAN%20OUTS.pdf
