The Lab has two storm water permits
One addresses the management of storm water during construction projects and the second permit requests that the Lab use best management practices (BMPs) to maintain storm water quality.
Construction Activities: Two projects are currently covered by the Lab's construction storm water permit (CEBAF Center Addition and the Trailer City removal). This permit applies to projects that would disturb one acre or more of land. The only remaining area that still needs attention for the CEBAF Center Addition project is the storm channel near the west end of the North Connector Road where it meets Rutherford Road (parking area adjacent to the 'Trailer City' area). All of the area where Trailer City 'was located' is still covered by the permit. Both areas must be stabilized to terminate the permit coverage. (Planting is to occur this fall.) As soon as these remaining areas are stabilized, Jefferson Lab will apply to terminate the permit. Erosion control measures must remain in place and Facilities and Logistics must continue to inspect the area and maintain control measures under the terms of the permit.
Just about the time we will be terminating this permit, a new permit will be required – to cover the planned new storm water retention pond that will be installed on the east end of the accelerator site. This new pond will handle current site storm water runoff issues in this watershed as well as manage the new storm water loading due to the new Hall D complex facilities and area roads.
All Site Activities: This permit covers all site activities that could affect the quality of storm water leaving the Jefferson Lab site. It reinforces the Lab awareness to keep pollutants out of any storm water channels. This permit is termed the Small Municipal Separate Storm Sewer System (MS4 for short) Permit. A portion of this permit is addressed by identifying BMPs. The Lab has done so which describe the methods by which Jefferson Lab implements the permit-required minimum control measures (MCMs). Jefferson Lab has met many of the goals that were set since getting the permit, with one important one being that the site has switched to a more environmentally friendly deicing compound that is now used throughout the site.
Following is an example of an MCM and one Lab BMP in use under this MS4 Permit at Jefferson Lab. For further information and the full list, refer to the EH&S Manual Appendix EPS33-R1 Jefferson Lab Best Management Practices and Measurable Goals. (This list of BMPs is being updated – provide suggestions for BMPs for possibly adding to the list to L. Even at lle@jlab.org.)
MCM 6 - Pollution prevention/good housekeeping for municipal operations
Pollution prevention/good housekeeping for site operations
- Incorporate the use of road salt alternatives for roadway deicing.
- Track the number and location of storage facilities and the percentage included in a regular inspection and maintenance program, with a goal of at least 1 inspection yearly.
- At least 90% of employees that handle salt (for each winter) are trained in salt application.
- Track the quantity of salt applied to roadways/walkways per fiscal year, with a goal of reducing the quantity used over the permit term.
- Track the quantity of alternative products used per fiscal year, with a goal of using a higher percentage of alternative products vs. salt over the permit term.
- Water quality downstream of a main usage area to be monitored if an area of excessive usage or unusual conditions is reported.
- Ensure performance objectives for building pest control crews are included in any subcontract.
- Verify that subcontractors and crews are Virginia certified before a contract is initiated.
- Periodically verify that the subcontractor is ensuring that any new hires or positions are provided a site-specific briefing. (annual)
- Maintain the Lab's "minimum-use/least-harmful" policy for pest control services. (verify annually)
