Harney Lane Landfill <br /> Page 2 of 3 <br /> ' Section 17708 - Drainage/Erosion <br /> I observed ponding on the surface of the site in several areas on <br /> the first day of the investigation (the 17th) during a rainstorm. <br /> The next day (the 18th) it was not raining and most of the water <br /> had drained with the exception of some ponding over the surface <br /> of the old fill area on the northern portion of the site. <br /> Differential settlement of this area and its lack of grading <br /> maintenance is the identified cause of the ponding in this area. <br /> Section 17710 - Grading of Fill Surfaces <br /> As indicated above, ponding was observed on the northern portion <br /> of the site. Grading was not established sufficiently to account <br /> for the settlement of older fill surfaces. An acceptable grading <br /> schedule has been submitted by the operator with the express <br /> intent of correcting this discrepancy while including it into the <br /> planning for the closure of the site. It has been noted that the <br /> forthcoming closure plan design for the site will correct the <br /> grading and drainage as the operation comes to a close. <br /> Section 17679- Final Slopes <br /> I observed that the final surface on the northern portion of the <br /> site appeared unfinished and not smoothly graded. It is apparent <br /> that the fill in the trench cuts in this area has subsided <br /> causing it to look rough and unfinished. The operator has not <br /> maintained the cover or drainage in this area and it is, thus, <br /> subject to ponding during periods of precipitation. <br /> Section 17732 - maintenance <br /> I observed inadequate repair of deteriorated grading and drainage <br /> conditions as noted above. <br /> INDETER14INATE <br /> This CAC Section was given an indeterminate status pending <br /> receipt of groundwater investigation data as reported to the <br /> RWQCB from the SWAT testing for the site. <br /> 17704 - Leachate Control <br /> Opiginal <br /> 81 ne <br /> Waste Maha%,Oment Specialist <br />
