EI Dorado Street, Stockton, San Joaquin County CONTACT(S): Terry Loeser, General Manager, The Learner Company INSPECTION DATE: 1 February 2008 INSPECTED BY: Mary Boyd, Regional Water Quality Control Board staff ACCOMPANIED BY: Jerry Loeser, The Learner Company OBSERVATIONS AND COMMENTS: Due to the recent rainstorms, lack of vegetative growth, and heavy mud layer on the top of the landfill cover, the inspection was limited to observations of the side slopes on the west, south, and east sides of the landfill cover: 1. The western side slope (facing EI Dorado Street) has sparse vegetation, has eroded, has at least three gullies, and numerous rills. The rills and gullies extend from the shoulder to the toe of the slope (see Photos 1 through 4). One section of this slope has sloughed off from mid -point of the slope to the toe of the slope, as shown in Photo 5. One gully (Photos 1 and 2) has erosion down to the clay layer, a depth of at least 1 -foot. 2. The southern slope (facing Duck Creek) is nearly bare of vegetation, as shown in Photos 6 and 7. This slope has numerous rills. 3. The eastern slope has little to no vegetation with fewer and less dense rills than the southern slope. Based on the ubiquitous nature of the rills, gullies, and absence of vegetation, staff notes that the Discharger has violated the conditions of Waste Discharge Requirements Order No. R5- 2007-0084 (WDRs) as follows: 1. The Discharge has failed to repair forthwith any breach or other cover problem discovered by periodic monitoring, as required by Section C.4 of the WDRs. 2. The Discharger has failed to inspect erosion control measures and has failed to implement and complete repairs prior to 1 October. In addition, the Discharger has failed to complete any necessary construction, maintenance, or repairs of precipitation and drainage control facilities to prevent erosion, flooding, and surface drainage from contacting or percolating through wastes, as required by Section C.5 of the WDRs. 3. The Discharger has failed to maintain the vegetative cover, provide fertilization as needed, and replant areas that exhibit sparse or inadequate growth, as required by Section C.6 of the WDRs. 4. The Discharger has failed to comply with Section E.1 of the WDRs that requires the Discharger to comply with all applicable provisions of Title 27 that are not specifically Approved:
