1128846 05/16/2024 Order Conditions Board staff received several odor complaints regarding the Sutter Plant in 2023 and 2024. During the inspection, Board staff investigated the area from which the complaints originated, spanning from Ustick Rd to Carter Ave and continuing through Carter Ave to Dallas St. While walking through this area, the odor was particularly noticeable, especially at the intersections of Ustick Rd and Carter Ave, as well as Carter Ave and Bollinger Ct. According to the Discharger, efforts are actively underway to identify and eliminate the source of the odor. The Discharger mentioned during the inspection that it is working with its consultant to develop a workplan that will identify the source of the odor and outline recommendations to eliminate it. According to WDRs 99-112 Provision B.6, ?objectionable odor originating at this facility shall not be perceivable beyond the limits of the disposal areas, wastewater transmission lines, or property owned by the Discharger.? Additionally, WDRs R5-2017-0085-002 Provision VII.C.4.c.v requires that objectionable odors shall not be perceivable beyond the limits of the facility. Since Board staff identified objectionable odors outside the Facility?s boundaries during the inspection, in violation of WDRs 99-112 and WDRs R5-2017-0085-002.

1132755 07/11/2024 Unauthorized Discharge A release occurred on the Aerojet GET pipeline near extraction well 4768.

Aerojet believes the release started on July 11; however, the exact release start date is unknown. The release reached Alder Creek, which flows into the American River. The pipeline that released this water conveys untreated groundwater from multiple extraction wells, so the contaminant concentrations in the discharged water can only be estimated based on individual extraction well flow rates and sample results. Aerojet provided the following total mass estimates for this accidental discharge: 3 grams NDMA, 32 grams TCE, and 13 grams perchlorate.
