CENTRAL VALLE EGIONAL WATER QUALITY I@NTROL BOARD INSPECTION REPORT DISCHARGER: Harney Lane Landfill LOCATION & COUNTY: Lodi, San Joaquin County CONTACT(S): Mike Carroll, San Joaquin County DPW INSPECTION DATE: 14 December 2009 INSPECTED BY: John Moody, Central Valley RWQCB ACCOMPANIED BY: Mike Carroll, San Joaquin County DPW OBSERVATIONS AND COMMENTS: Central Valley Water Board permitting staff conducted an inspection of the landfill to view areas regulated under the WDRs and do a visual check of the overall operation of the major landfill facilities. Areas viewed included the-iandfitt-nodules; storm drains, and-surface water monitoring points. The inspection started at about 1:30 p.m. The weather was cloudy and cool, about 55 °F. Site conditions were damp in most areas due to recent heavy rains (about 1.5 inches). The landfill deck and side slopes had healthy vegetative cover and appeared to be adequately graded for drainage. All slopes appeared to be well drained and I did not see any significant erosion or other repair issues. The storm drains also appeared to be in good condition and operating normally. See Photos 1 through 4. All monitoring points appeared to be representative and appropriate, although the operator mentioned that the downstream monitoring point historically used for surface water monitoring (i.e., S-2 immediately downstream of the sedimentation basin outfall) is actually a few hundred feet upstream of the location shown in the WDR map. Since the down stream monitoring location was not changed during the last WDR revision, staff advised the Discharger to continue monitoring at the actual historical location pending the next revision of the MRP. See Attachment 2. I also visited the area on the northwest side of the site (adjacent to the migrant labor camp) where the operator plans to install a groundwater monitoring well required under the WDRs. The operator indicated that, due to the soft soil conditions caused by recent rain, drilling of the well would have to be rescheduled. See Photo 5. 1 also viewed an area in the northwest corner of the site where the operator is considering installing an additional background monitoring well as required under the WDRs. The operator is weighing the benefits of the onsite location with the risks of having to install another well further upgradient in the event it is determined that the onsite well is impacted and cannot be used for background monitoring. So far, however, the offsite owner has not responded to the County's inquiries about installing such a well. I left the site at 3:15 p.m. u ` Joh,n„Moody Water R sdurces Control Engineer Approved: 1770683
