I TIMOTHYA. CRANDALL <br /> J-MManufacturing Closure Design, San Joaquin County, California. This <br /> manufacturing site contains a number of asbestos waste landfills plus asbestos <br /> contamination in surface soil. Mr. Crandall conducted a surface soil investigation <br /> and prepared a closure remediation plan for the site. Mr. Crandall negotiated with <br /> the regulatory agencies and obtained concessions from the regulators that saved <br /> the client approximately $500,000 in construction costs. Mr. Crandall prepared <br /> the closure drawings, general and technical specifications, construction quality <br /> assurance plan, and other bidding information. The project is currently out to bid <br /> and Mr. Crandall will serve as the Construction Quality Assurance Officer when <br /> construction begins in the spring of 1995. <br /> Queens Creek Landfill Design, Phoenix, Arizona. Mr. Crandall managed <br /> preparation of designs for an expansion of the landfill (composite liner) and closure <br /> configuration of the landfill. A groundwater monitoring plan, operations plan and <br /> closure plan was also prepared for submission to the regulatory agencies. <br /> Mt. Gaines Consolidated Mine Heap Leach Liner Inspection,Mariposa County, <br /> California. Mr. Crandall inspected the condition of an existing 60 mil HDPE liner <br /> on two surface impoundments that contain cyanide leachate from the heap leach <br /> operation. Mr. Crandall inspected the liners for environmental degradation, <br /> punctures, seam defects, and other potential problems. Once the liners were <br /> declared competent, the regulatory agencies allowed mine owners to commence <br /> operations. <br /> Harney Lane Landfill Cap Redesign, San Joaquin County, California. Mr. <br /> Crandall assessed the viability of an alternative cap design using the leachate <br /> generation model HELP. Mr. Crandall was able to demonstrate to the regulatory <br /> agencies that the altemative capping design would not result in a degradation in <br /> performance of the cap and the design change was accepted by the regulators. <br /> This resulted in a savings of approximately $60,000 in construction costs. <br /> Permitting and Design, Confidential Client, Willows, California. Participated in <br /> the permitting and conceptual design of 16 surface impoundments and 6 landfills <br /> for a saline wastewater and drilling mud facility; also installed vadose zone <br /> monitoring equipment. <br /> SWAT, Castle Air Force Base, Merced, California. Participated in the preparation <br /> of a SWAT proposal for a landfill that received a variety of waste. <br /> Plans, Technical Specifications and Construction Observation, Cove Contractors <br /> Landfill, Stockton, California. Mr. Crandall prepared drawings, technical <br /> specifications and conducted the bidding for installation of a temporary compacted <br /> soil cap on the Cove Contractors Landfill. Mr. Crandall was the Construction <br /> Quality Assurance Officer. During installation of the cap, asbestos was <br /> unexpectedly encountered in the waste. Rather than excavate the waste to match <br /> design grades, Mr. Crandall revised the grading design so that the cap could be <br /> installed without excavation of the asbestos waste. This design change resulted in <br /> significant savings for the client. Mr. Crandall is currently preparing a design for <br /> and final cap, work that will include preparation of project drawings, specifications <br /> E21208(03/93) 2 <br />
