<br />COST ESTIMATE SUMMARY Y
<br />Notes:
<br />See Attachment No. 1 for labor and equipment rates per hour utilized in the development of Post -Closure Cost Estimate. The material
<br />unit prices from Table 3 were utilized to develop material costs for Items 6, 7, and 10. Quantities were based on assumptions made by
<br />SWT Engineering based on our experience with other landfills. Labor and rates were obtained from the State of California Industrial
<br />Relations; prevailing wage schedule pursuant to California Labor Code Part 7, Chapter 1, Article 2, Sections 1770, 1773, and 1773.1.
<br />Equipment rental rates were obtained from the CalTrans Labor Surcharge and Equipment Rental Rates effective April 1, 2007 through
<br />March 31, 2008. SWT was also provided current invoices/costs for all environmental services currently being conducted by Forward
<br />Landfill for the period of January 2007 through January 2008 for consideration and use in developing this post -closure cost estimate.
<br />(1) Cost assumptions for system maintenance/repair include labor (Sr. Engineering Technician), a pick-up truck, gas meter, tools,
<br />miscellaneous items, Backhoe (CAT 44613) and materials to replace up to 4 collection wells per year to average depth of 150 feet and
<br />one LFG migration monitoring probe to the depth of refuse annually.
<br />Cost assumption for system monitoring/testing includes labor (Sr. Engineering Technician), gas meter, sampling materials, pick-up
<br />truck, flare source testing, laboratory, management by Sr. Engineer (based on a review of current rates for professional consulting
<br />firms) and reporting per regulations.
<br />(2) Cost assumption for system maintenance/repair includes labor (Sr. Engineering Technician) equipment (pick-up truck, tools,
<br />pump, etc.) and replacement of one monitoring well every two years based on the following: $8,700 for similar well 50 -feet deep
<br />including permit at $500 and geologging at $2,000.
<br />Cost assumptions for system monitoring includes labor (Sr. Engineering Technician), pick-up truck, sampling equipment, laboratory,
<br />management by a Sr. Geologist (based on a review of current rates for professional consulting firms), analysis by a geologist and
<br />preparation of necessary reports for the RWQCB.
<br />(3) Cost assumptions for system operation and maintenance include labor (Sr. Engineering Technician), a pick-up truck, tools, parts,
<br />electricity, and filter mediums.
<br />(4) Cost assumptions for system maintenance/repair include labor (Sr. Engineering Technician), a pick-up truck, tools, miscellaneous
<br />items, and materials.
<br />Cost assumption for system monitoring/testing includes labor (Sr. Engineering Technician), gas meter, sampling materials, pick-up
<br />truck, laboratory, management by Sr. Engineer (based on a review of current rates for professional consulting firms), analysis by a
<br />geologist, and reporting per regulations.
<br />(5) Cost assumptions for system maintenance/repair include labor (Sr. Engineering Technician), a pick-up truck, tools, miscellaneous
<br />items, and materials.
<br />Cost assumption for system monitoring/testing includes labor (Sr. Engineering Technician), sampling materials, pick-up truck,
<br />laboratory, management by Sr. Engineer (based on a review of current rates for professional consulting firms), analysis by a geologist,
<br />and reporting per regulations.
<br />(6) Cost assumptions for system maintenance/repair include labor (Sr. Engineering Technician, heavy equipment operators), a pick-up
<br />truck, tools, miscellaneous items, loader (CAT 966G), dozer (CAT D8 -N), dump truck (22 tons), a 3,000 -gallon water truck, and
<br />materials to replace 1 acre each of lined and unlined final cover.
<br />(7) Cost assumptions for system maintenance/repair include labor (Sr. Engineering Technician), a pick-up truck, tools, miscellaneous
<br />items, and materials to provide rodent control and hydroseeding and add soil amendments to 1 acre of final cover each year.
<br />(8) Cost assumptions for system maintenance/repair include labor (Sr. Engineering Technician), a pick-up truck, tools, miscellaneous
<br />items, Motorgrader (CAT 14-H), and materials to repair 100 If of access road each year.
<br />(9) Cost assumptions for system maintenance/repair include labor (Sr. Engineering Technician), a pick-up truck, high-pressure sprayer,
<br />tools, Backhoe (CAT 44613) and materials to replace up to 150 If of perimeter channel and 100 If of 24" HDPE downdrain pipe each
<br />year.
<br />(10) Cost assumptions for system maintenance/repair include labor (Sr. Engineering Technician), a pick-up truck, tools, and materials
<br />to replace up to 100 If of fencing each year.
