2. EMS is Environmental Management System. It is the environmental component of the Jefferson Lab ISMS. The System comprises a tiered series of documents: The EMS Plan Fifteen EMPs (procedures) The Lab-wide implementing documents to control environmental hazards, such as SOPs

3. This is EMS-talk for the most important potential environmental hazards at the facility. Significant Aspects are systematically identified and prioritized on a regular basis. The current list of Significant Aspects includes: Industrial wastewater and releases to surface water Hazardous and nonhazardous waste Low level radioactive waste Activation of soil and groundwater Nanomaterials Water use Energy use Ozone-Depleting Substances

4. Lab-wide policies and plans for water and energy conservation, pollution prevention, and recycling are designed to address some of these aspects. Task- or area-specific SOPs address others. Some require multiple approaches.

5. Every new activity or substantive change in materials or operations should be reviewed for environmental considerations.

6. Not every Significant Aspect (such as habitat protection) is associated with a law, permit, or regulation … but many are. The EMS is set up to: Make sure we have the knowledge and tools to achieve and maintain compliance Periodically assess our degree of compliance Annually report on our compliance status (through the Site Environmental Report) (http://www.jlab.org/ehs/ser/)

7. Industrial wastewater: limits on pH (cannot be below 5) and tritium. Groundwater quality: activation products are limited. Groundwater quantity: dewatering under Halls. Stormwater runoff: Associated with construction As a result of everyday operations

8. Training Environmental data quality Top management awareness of environmental issues Control of records and documents Communications Emergency preparedness

9. Know how your job can affect the environment. We are all responsible for water and energy conservation. Properly manage wastes; use less hazardous substances; use correct disposal methods. Pass along ideas for improved environmental protection. New or changed activities or materials need an evaluation. Get help from ES&H professionals if needed. Report possible releases to the environment immediately.
