Wastewater Discharge Permits and Documentation
| Activity |
Responsible Individual |
Required Action |
| Obtain Permission to Discharge Wastewater |
Members of the Workforce |
- Submit documentation to your water quality contact for discharge permits and request written approval for all process discharges. Include in the documentation the amount, frequency, location, composition, and process associated with a discharge to the sanitary sewer system, except for sanitary waste.
- To obtain one-year, site-specific approval to discharge to the sanitary sewer system or to discharge a new or altered wastewater stream— including wastewater streams that have been altered as a result of connecting or modifying any process equipment or activity that discharges to the sanitary sewer system—.provide details to the water quality contact on all new and existing processes that discharge or have the potential to discharge to a publicly-owned treatment works (POTW). Note: This information is compiled and submitted to the regulatory control authority, which analyzes the submittal and establishes limits and prohibitions on pollutants that may disrupt the operation of the POTW. See ESH100.2.ENV.6 under Implementing Tools below.
- Before beginning new processes, obtain through the water quality contact for discharge permits the appropriate regulatory agency approval for wastewater discharges.
- Maintain copies of discharge approvals and pertinent environmental permits and document your processes to show compliance with permit requirements. Examples of such documentation include:
- Technical work documents describing the process.
- Operational logs documenting process discharges.

Liquid Effluent
| Activity |
Responsible Individual |
Required Action |
| Discharge Contents of LECS Holding Tanks |
Members of the Workforce |
- Do not discharge or dispose of the contents of SNL's Liquid Effluent Control System (LECS) holding tanks until they have been screened for pH and specific contaminants, such as radioactive materials or metals.
- Consult the discharges standards screening contact and refer to Table 1 below for disposal options.
|
| Discharge Contents of LECS Holding Tanks |
Members of the Workforce at SNL/CA |
Only Members of the Workforce who work in the Environmental Monitoring Program are authorized to discharge LECS holding tanks. |
Table 1. Disposal Options for Liquid Effluent Control System Holding Tanks
| If Tank Contents ... |
Then... |
| Meet site discharge limits |
Contents are released to the site's main sanitary sewer system. |
| Contain pollutants above discharge limits, but below hazardous waste criteria |
Disposal is determined on a case-by-case basis at each site. |
| Meet hazardous waste criteria |
Contents are handled and disposed of as appropriate through the waste pickup, hazardous contact. |
Discharge Limitations and Prohibitions
| Activity |
Responsible Individual |
Required Action |
| Discharge Other Wastewater |
Members of the Workforce |
- Notify the water quality contact for approval before discharging process water with any pollutants that can interfere with or disrupt the operation or performance of a publicly-owned treatment works (POTW). Note: For examples of pollutants and the New Mexico and California POTW standards that apply to them, refer to ESH100.2.ENV.6 under Implementing Tools below.
- Do not discharge wastewater that contains pollutants such as heavy metals or other toxic substances in excess of regulatory limits, as indicated in ESH100.2.ENV.6 under Implementing Tools. Call the water quality contact for discharge guidance.
- Do not discharge wastewater with water added for the sole purpose of diluting or reducing the concentration of pollutants for discharge.
|
| Discharge Other Wastewater |
Members of the Workforce at SNL/CA |
- Do not discharge cooling water, storm water, reject water, any kind of unpolluted water, or any combination of these kinds of water in quantities greater than 2500 gallons per day without prior approval from the water quality contact.
- Notify the water quality contact of all discharges that exceed 1000 gallons per day.
|
One-Time or Batch Discharges
| Activity |
Responsible Individual |
Required Action |
| Arrange for an Evaluation |
Mangers |
Call the water quality contact to arrange an evaluation of one-time or batch discharges, which shall be reviewed on a case-by-case basis to determine whether the release is acceptable under current regulatory requirements or if it must be reported as an occurrence. |
Reporting Spills and Accidental Releases
| Activity |
Responsible Individual |
Required Action |
| Report Spills and Accidental Releases |
Members of the Workforce |
- Report spills and accidental releases to the sanitary sewer system immediately according to requirements in ESH100.4.RPT.4, Report Environmental Releases.
- Coordinate these reports with the water quality, wastewater contact, who will transmit the reports to DOE. DOE will then submit reports to the appropriate regulators.
