Lorencito Fill Report Review May 29, 2002 Page 9 of 14 Pages covered with excess spoil. The color photographs placed. Fill accompanying each certified report shall be taken in was being adequate size and number with enough terrain or other placed. physical features of the site shown to provide a relative scale to the photographs and to specifically and clearly identi the site. Rule 4.09.1(13) If the disposal area contains springs, natural or manmade Yes. The watercourses, or wet-weather seeps, an underdrain system report states consisting of durable non-acid-forming and that there non-toxic-forming rock shall be constructed from the wet was no areas in a manner that prevents infiltration of the water evidence of into the spoil material. The underdrain system shall be springs or protected by an adequate filter and shall be designed and seeps. constructed using standard geotechnical engineering methods. ' By signature titles, Ronald G. Thompson was the inspector. The certification statement does not say that Thompson was under the direct supervision of McGlothlin. There is a PE stamp on the report. z The report is dated February 23, 2002, but does not indicate the date of inspection. However, the photographs are dated February 23, 2002. Your draft asks for dates of the inspections. 5 The report was dated February 23, 2002 but the date of inspection is not indicated. It was received at the Division on Apri122, 2002. The submittal is not in compliance with this rule. b By omission, one might infer compliance. However, better engineering practice would be to include a statement that none exists. Summary: I suggest you delete your draft statement that "No compaction data was collected or indicted. The specifications only state that compaction will be by dozers and trucks. The report states that this criterion was met. Your discussion on placement of fill in the photograph might be softened by recommending the discussion of the picture be expanded to illustrate the 50-foot zone being placed in horizontal layers and compacted by dozers and trucks (if such is the case in the photograph). A dozer would then make a final dress of the fill as maybe shown. Recommend the addition to your draft comments (Disposal of Excess Spill Fill Area #9 First Quarter 2002 Certification February 23, 2002) the following: Please add to the certification (page 2) that Ronald G. Thompson, a qualified professional specialist experienced in construction of earth and rockfill embankments, accomplished the inspection under the direction of Charles W. McGlothlin. Please add the date of inspection to the report.
