  PROFESSIONAL EXPERIENCE

Mr. Walker has more than 20 years experience in solid waste with both the private and public sectors of the industry.  He has directed and managed engineering projects on recycling, materials recovery facility, landfill gas, landfill design and closure, permitting, and regulatory compliance.

The following is a partial listing of representative projects:

• Managed two major Subtitle "D" landfill expansion projects for a private waste company in Palmdale, California,, located in a high desert arid climate.  Unique design features included a landfill cell wall consisting of a vertical gabion wall covered by GCL and FML. Regional Water Quality Control Board and California Integrated Waste Management Board approved and permitted the project.

• Director of remediation engineering for gas migration control on a Class I landfill (Superfund site).  Mr. Walker was responsible for re-entry of 21 evacuated residents.

• Directed and conducted all financial assurance evaluations at three Waste Management sites in arid high desert locations in California.  Prepared preliminary closure plans necessary for costs estimates.  Results were used to determine tipping fee set aside for closure and 30 year post closure care. Substantial savings accrued to Waste Management by not initiating a prescriptive subtitle “D” cap, but elected to use a monolithic cover as an engineered alternative.

• Responsible for gas migration control designs at four sites in Ventura, California.  Results were used in the preparation of closure plans at selected sites.

• Responsible for the design, engineering, construction management, and operation of a gas collection system at a large EPA superfund site in Tacoma, Washington. Completed construction and installation of 120 wells in 10 days.  Emergency response action required landfill gas facility to be operational within 30 days. Start up was on schedule.

• Conducted air toxics testing at nine landfills located in Tulare County, California.  The landfills consisted of Class I and II active and closed landfills.

• Conducted a waste shed composition study for the City of Whittier, California.

• Conducted an investigation of the feasibility of 20 waste-to-energy modular incinerators in Newport Beach, California.

• Managed horizontal landfill expansion engineering design project for the City of Glendale, California.

• Directed the effort to redesign a 200-foot vertical lift on a landfill in San Marcos, California.

• Directed preparation of preliminary designs of a 4,000 ton-per-day material recovery facility (MRF) in Puente Hills, California.

• Directed design efforts for a 1,800 ton-per-day materials recovery facility (MRF) in Oxnard, California.

• Prepared all air quality, fire, building, safety, and waste discharge permits for a facility (MRF) in Sun Valley, California.

• Prepared all air quality permits for a gas migration and utilization system in the City of Industry, California.

• Performed a regulatory assessment of the implementation of a landfill gas to electricity project in Santa Barbara, California.

• Directed and conducted financial assurance evaluations for two landfills at Lake County, California. Results were used by the county to determine financial commitment of any potential buyer of the existing landfill and the adjacent future landfill expansion. The County benefited substantial cost savings by not implementing unnecessary gas migration controls.

• Directed and conducted several financial assurance evaluations for the City of Glendale, California. The purpose of the analysis was to determine if it was cost effective to expand the city owned landfill or continue to transfer haul to the Puente Hills landfill.

• Directed and performed financial analysis for closure post closure care for the Cummings Road Landfill in Eureka, California.
