TITLE:	ES&H Manual
DOCUMENT ID:	Chapter 8020 Appendix T2 Discharges to the Hampton Roads Sanitation District (HRSD) System

1.0 Purpose

Jefferson Lab’s sewer system discharges to the Hampton Roads Sanitation District (HRSD) wastewater treatment plant in Newport News under permit (HRSD 0117). The treated wastewater subsequently discharges to the James River.

Some wastewaters, such as those containing oil, chemicals, or grease, can adversely affect the routine operation of wastewater treatment facilities that, in turn, cause unacceptable effluent to be discharged by HRSD to surface waters. Only wastes specifically allowed by permit, or those individually approved by HRSD, should be discharged to drains, sinks, and toilets.

2.0 Scope

This chapter provides Jefferson Lab staff, Users, and Subcontractors with information that will assure discharges through the municipal sewer (HRSD) remain within all permit constraints.

3.0 Responsibilities

NOTE: Management authority may be delegated to a task qualified Jefferson Lab employee at the discretion of the responsible manager.

3.1 Everyone at Jefferson Lab

· There are certain materials and chemicals that are strictly prohibited by HRSD from disposal down the drain. If you are uncertain about using any particular substance that could end up down the drain, contact the Jefferson Lab Subject Matter Expert (x7308) for assistance.

NOTE: Water may not be added to wastewater for the purpose of diluting wastes that would otherwise be unacceptable for discharge.

· The HRSD permit contains self-reporting requirements, including when an unpermitted discharge occurs. In the case of an unpermitted discharge, contact 876-1750 to notify the ES&H Reporting Manager, who will handle external reporting.

NOTE: If potentially activated water is involved, contact the Radiation Control Department (RadCon) for disposal.

3.2 Facilities Management & Logistics

· Arrange with ES&H to request authorization from HRSD when the need to use different cooling tower treatment chemicals is identified, or if any other discharges that are new or modified are anticipated.

· Maintain metering system, conduct monthly meter readings, and transfer that data to the flow-calculation report that must be provided to HRSD each month.

· Conduct 7-day meter readings annually.

3.3 Superconducting Radio Frequency (SRF) Department

· Ensure compliance with pH limits and related permit terms.

· Maintain and manage acid neutralization systems.

3.4 Radiation Control Department

· Review and maintain the activated water management programs in accordance with permit requirements.

3.5 ES&H

· Review proposals for new/modified discharges to the laboratory’s HRSD system and manage the regulatory approval process if necessary.

· Prepare all necessary reports for submission to HRSD.

4.0 Process Steps and Expectations

4.1 The following wastewaters are specifically approved for discharge to HRSD via our permit:

· Typical household and sanitary wastewater

· Condensate from cooling equipment

· Acid rinsewater from SRF, after pH adjustment

· Cooling tower blowdown and maintenance water, with pre-approved chemicals

· Kitchen wastewater from cafeteria, via the grease trap

· Beam dump cooling water via the Tritium Monitoring and Disposal Unit (TMDU), subject to radiological limits

· Water from floor drains, groundwater incursion, and condensate from the Accelerator enclosure and Halls A, B, C and D, subject to radiological limits

· Floor drains in the Test Lab, TED, CHL, Forestry, Guard Shack, FEL, SSC, and EEL. However, floor drains must be protected from chemical and oil spills

4.2 All other potential wastewater discharges, from new or changed processes or activities, cannot be discharged without authorization under the HRSD permit. In general, the review and approval process is as follows:

Step 1: Gather information on the amount of flow, frequency and duration of discharge, and possible chemical constituents.

Step 2: Consult with ES&H. Preliminary coordination to allow sufficient time to obtain samples for analysis.

Step 3: ES&H collects a representative sample of the proposed special discharge and submits to subcontractor environmental analytical lab for analysis of: chromium, cadmium, lead, copper, nickel, zinc, pH, chemical oxygen demand and biological oxygen demand.

Step 4: ES&H reviews analytical results for subject sample and determines if results are below any HRSD permit compliance thresholds for each constituent analyzed. If results are compliant with permit requirements, the discharge is authorized to occur. If the results are not compliant with permit requirements, ES&H will provide disposal alternatives (such as offsite transfer as industrial waste).
