2. The Discharger failed to notify Water Board staff of concentration limit exceedances and to complete MRP and 2003 Standard Provision required resampling and reporting. Two concentration limit exceedances were noted in the Annual Report, one for electrical conductivity in MW-21 and one for dissolved arsenic in MW 12A. Additionally, although not discussed in the Annual Report, exceedances of chromium (VI) in MW-7R, and dissolved arsenic in MW-12A were noted in the 2021 Semi-Annual Report. However, these exceedances are based on new intrawell statistics calculated for each individual site well. They are not based on interwell statistics calculated using MW-12 as the background well as outlined in the WDRs and MRP. A separate report outlining the discharger?s proposal to change how water quality protection standards are calculated and applied at the site will be required. |

Unauthorized Discharge |
1. The Discharger failed to Notify Water Board staff of a release of waste or provided written notification as required by Section B.3 of Monitoring and Reporting Program R5 2010-0125 (MRP). This section states in part: If the Discharger determines that there is ? physical evidence of a release, the Discharger shall immediately notify the Central Valley Water Board verbally ? shall provide written notification by certified mail within seven days of such determination and implement the resampling procedure in Section C.5 of this MRP and the requirements in Sections X.C and/or X.D of the Standard Provisions The Annual Report documents a release of a small volume of liquid from the return to transfer line on 7 May 2021, and that this release impacted site soil. An investigation was completed, soil samples were collected, and the results of the confirmation soil samples indicate that residual concentrations do not exceed commercial use Environmental Screening Levels for soil. These results are documented in the 30 July 2021 2021 Semi-Annual Report. However, the WDRs require Water Board staff to be notified immediately of any release that occurs outside the limits of the surface impoundment and/or the site?s paved containment system as outlined above. |
