If the turbidity exceeds 250 NTU at any time, the foilowing steps will be conducted: Notify DOE by phone within 24 hours of analysis (See Table 5.1 for contact information). 2. Continue sampling daily during emergency overflow event. Initiate additional treatment BMPs such as offsite treatment, infiltrations, filtration and chemical treatment within 24 hours, and implement those additional treatment BMPs as soon as possible, but within a minimum of severi days. 3. Describe inspection results and remedial actions taken in the site log book and in monthly DMR as described in Section 7.0 of this TESC Plan and SWPPP. 6.2.2 pH Sampling and monitoring for pH will be conducted only during a manually controlled emergency overflow event. Samples will be collected daily during emergency overflow at the monitoring point present in each line downstream of the emergency overflow valve. Samples will be analyzed for pH using a calibrated pH meter arid recorded in the site log book. The key benchmark pH value for storm water is a maximum of 8.5, and a minimum of 5.5. If a pH greater than 8.5, or less than 5.5, is measured at the monitoring point that has the potential to discharge to surface water, the following steps will be conducted. 1. Prevent (detain) all discharges from leaving the site and entering surface waters or storm drains if the pH is above 8.5 or below 5.5. 2. Implement COz sparging or dry ice treatment in accordance with DOE BMP C252 (Appendix D). 3. Describe inspection results and remedial actions that are taken in the site log book and in monthly DMR as described in Section 7.0 of this document.
