Note: Uploading of all manifest or other documentation is not required, however they should be available for review at the time of verification.
What is the intent of the question?
The intent of this question is for facilities to demonstrate that processes are in place to obtain and retain information related to the handling, transportation, processing, and disposal of industrial wastewater sludge and to ensure that any third-party waste vendors have the required legal approvals to receive, process and dispose of the facility’s sludge.
Technical Guidance:
To ensure proper accountability, facilities should have established processes in place to maintain documentation related to the handling, transportation, processing, and disposal of industrial wastewater sludge. Often the minimum requirements for generating and maintaining documentation related to waste disposal is governed by legal requirements (particularly for hazardous wastes) and all applicable requirements should be met by facilities.
In addition to any legal requirements, facilities should ensure that a waste manifest or a similar local transport document that contains the following information is obtained and maintained for each sludge shipment as a good practice. If needed this additional information can be requested from waste vendors:
- Shipper (the facility generating the sludge).
- Mass or volume of net shipment.
- Transporter’s company name.
- Shipment/Receiving dates
- Name of the disposal or processing facility that the sludge was shipped to.
Facilities should also ensure that any third-party waste vendors used have the required legal approvals to receive, process and dispose of the facility’s sludge. Facilities should ensure that part of the waste vendor approvals process include the verification of all legally required approvals (e.g., licenses and permits). It is considered a good practice (if not legally required) for facilities to request and maintain up-to-date and valid copies of vendor approvals onsite.

The intent of this question is for facilities to demonstrate that their wastewater is being tested against a wastewater standard in addition to any legally required testing.
Technical Guidance
The standards referred to in this question refer to industry standards, and the intention is to evaluate compliance beyond basic legal discharge requirements.
Industry standards and tools are developed to support facilities in the proper management and reduction of hazardous pollutants discharged in wastewater to the environment. These tools intend to provide consistent methodologies to identify, monitor and report discharge of hazardous pollutants. They also strive to support facilities in managing and reducing hazardous discharges by establishing progressive discharge limits that go beyond basic legal compliance.
Different standards or tools may have different requirements for monitoring and reporting of wastewater data (e.g., the type and frequency of reporting, types of pollutants that must be monitored/reported, or testing methodologies, etc.) When adopting an industry standard, facilities should review the guideline to determine the monitoring and reporting requirements that apply to their operations and put in place procedures to meet the required monitoring and reporting requirements.
Examples of industry guidance/tools for wastewater include:
- The ZDHC suite of guidelines which can be downloaded here: https://www.roadmaptozero.com/output
