  PROFESSIONAL EXPERIENCE

Mr. Long has a 22-year record of successfully managing environmental, geotechnical and construction projects for the petroleum, chemical, transportation, utility and manufacturing industries. His experience includes the management of multi-disciplined technical staff for regulatory compliance issues, investigations, feasibility studies, systems design, operations and maintenance. His experience also includes monitoring and remedial construction for projects ranging in size up to $20 million dollars.

Environmental Engineering--

  • Principal Civil and Construction Engineer for an engineering efficiency review of a Engineering: multimillion dollar low level radioactive soil removal (250,000 cubic yards) project, State and National Superfund Site, in West Chicago, Illinois. This third party review involved the evaluation of subcontracts, costing and productivity of materials handling and rail car loading. The result of the review increased client awareness of actual costs, provided tighter control of subcontractor’s costs and confirmed that the owner had diligent personnel attached to the $200 million project.
  • At numerous sites throughout California, Mr. Long managed underground storage tank remediation programs for Unocal and Conoco Oil Companies. The multi-million-dollar programs included agency negotiation, site investigations, feasibility studies, remedial action plans, treatment system implementation, operation and maintenance, and quarterly monitoring. Remediation included pump and treat, vacuum extraction, bioremediation, dig and haul, etc.
  • Mr. Long was the lead engineer at the Santa Fe Inter-modal Terminal in San Bernardino, California. He has completed the design and construction management of a $2 million, 7,000-scfm, soil vapor phase treatment system for the removal of volatile organic compounds.
  • Environmental Engineer involved in planning and strategy sessions for the redevelopment of the Sacramento Rail Yard. This project includes critical path scheduling and costing for remediation of multiple contaminate sites, geotechnical consideration for the construction of a ½-million-cubic-yard Class R landfill, and materials handling planning.
  • Authored the Remedial Design and Implementation Plan (RDIP) for PCB-impacted soil, Aydin State Superfund, Palo Alto, California.
  • Managed a $2 million multi-chemical groundwater treatment system design along with its construction on a 100-acre Chemical Plant in Antioch, California. The system included co-mingling plumes, 20 cluster wells, 200-gpm air stripping tower with aqueous phase carbon polishing and vapor phase carbon off-gas treatment. Using steam, the vapor phase carbon unit was designed for onsite regeneration.
  • Author for Storm Water Pollution Presentation Plans (SWPPP), California Army National Guard, Camp San Louis Obispo, Fresno AVCRAD and Camp Roberts military installations. These plans included thousands of acres and multiple drainage discharge locations, with special emphasis on Total Suspended Solids and metals loading to receiving streams.
  • Responsible engineer for the Storm Water Pollution Prevention Plan for Conoco Asphalt Terminal located in Elk Grove, California. Mr. Long performed the initial sampling events for tills project.
  • Provided sampling and consultation for an Odor Abatement Study, Cal Oils, Richmond, California. The study included establishment of baseline odor and chemical composition of vapors emanating from the corn germ extraction facility. Point sources within the facility were identified and an odor capture and destruction system was evaluated. One of the options evaluated was a gas-fired turbine with regenerative electric power capabilities.
  • Remediation projects range from service station sites to 100-acre chemical plants. Types of contaminants encountered typically range from gasoline to crude oil, organic lead, mercury, and arsenic to TCE, TCA, PCE and other solvents. He was responsible for the design and construction of a $2.5 million dollar pump and treat system for a major chemical plant in California. The systems include air stripping, off-gas air treatment with vapor phase carbon and aqueous phase liquid carbon polishing to remove organic lead.
  • Managed the groundwater and vapor extraction systems Operation and Maintenance Program ($1 million annual budget) for Southern Pacific Railroad in Sacramento, California. This program included multi-phase extraction systems, catalytic off-gas treatment, off-gas scrubbing, and groundwater air stripping and carbon treatment.

Geotechnical Engineering--

  • Geotechnical Consultant on the Federal Courthouse excavation-dewatering project for Southern Pacific Railroad located in Sacramento, California. This project included groundwater modeling, flow characteristics, and predictive impact of local chemicals in groundwater. We developed groundwater treatment scenarios for contingency implementation if the events that impacted groundwater chemicals were beyond discharge requirements.
  • As the Geotechnical Engineer for the project, he designed an erosion control and countermeasures for a 50,000-cubic-yard earth flow at Camp San Luis Obispo. The study included hydraulic and slope stability calculations, sediment retention basin and earth structure’s design.
  • Geotechnical and construction consultant for the design and installation of a 60-feet deep soil mixing chemical barrier wall installed by GeoCon at the Sacramento rail yard. Included in the project were design drawings, specification, contracting, permitting, and construction performance monitoring.
  • Responsible engineer for hundreds of geotechnical investigations, foundation designs and earthwork construction. Geotechnical projects varied from retaining walls to 9-story hotels to 1 million-cubic-yard slope stability studies and mass grading, moving millions of cubic yards of earth.
  • Geotechnical Engineer for corrective measures on the Pittman Canal landslide and erosion from storm damage of 1985. Landslide damage included 1 million cubic yards of earth flow materials. Corrective measures included regrading, gabion wall construction, subdrainage and slope flattening.
  • Mr. Long was the Geotechnical Engineer for PG&E’s Drum Reservoir sediment removal project. A reservoir sediment removal study was completed which lead to the design of a 50-foot-high earthen sediment retention dam. The study involved offshore sediment drilling, sampling, gold assay and economic evaluations, 300,000 cubic yards of sediment removal, retention dam construction, area drainage improvement and construction monitoring.

Contractor and/or Construction Management--

  • Performed above ground bioremediation (landfarming) of 2,000 cubic yards of diesel impacted soil, Catellus Corp., Huron, California. The treatment included irrigation management, nutrient addition and periodic soil mixing.
  • Design and construction management of a dioxin plume encapsulation system, consisting of a 35-foot deep slurry trench with HDPE barrier liner and multi-media cap at a State Superfund site, Port of Oakland, California. Mr. Long changed the initial feasibility study design to one that was more practical and constructable, thus saving the client over a half million dollars.
  • Designed and constructed an enhanced in situ bioremediation treatment system for a fuel hydrocarbon spill. The system consisted of groundwater extraction and re-injection using hydrogen peroxide as the oxygen source for a redevelopment site in San Jose.
  • Performed the surgical removal of hydrocarbon-impacted soil, the impacted soil was located from 60 to 80 feed below the ground, using large diameter augers for Ace Oil State Superfund, Galt, California. Using large diameter drilling techniques to remove the impacted soil allowed removal without massive excavation and shoring, thereby saving hundreds of thousands of dollars.
  • Designed and constructed a 50-foot deep excavation for the Los Angeles Center development removing 50,000 cubic yards of soil, of which 2,000 cubic yards were fuel-impacted, in downtown Los Angeles. The work involved many meetings with multi-party, multi-consultant and multi-legal council, on a very visual and sensitive site subject to development of a skyscraper. The impacted soil was landfarmed on site and then removed.
  • Mr. Long has significant hands-on experience and training in kinetics and chemistry of explosives, recognition/classification, safe handling/remote removal procedures and remediation (destruction, chemical stabilization and bioremediation). He was the responsible engineer and contractor on a $2 million removal of 2,000 DNT & TNT barrels and drums located in solid waste landfill at an explosive site in the State of Washington. He also provided consultation for the assessment of a 1,000-acre explosive manufacturing site in Colorado that contained acid spills, nitroglycerin, PETN, black powder, etc. He has been involved with State Superfund and RCRA remedial investigation, feasibility studies, and corrective actions in the States of Montana, Colorado, and Washington.
