PROJECT EXPERIENCE

ENVIRONMENTAL CONSULTING

Village Life, LLC | Fruhling Pit | Bothell, Washington | 2018 | Project manager and engineer

Village Life is considering the purchase of the 26 acre Fruhling Pit for a residential development. Fruhling Pit had accepted substantial amounts of wood debris and hog fuel which are now generating methane. Gary lead a team that researched past documents, assessed the methane concentrations near the surface and monitored existing gas probes, tested vapors for typical landfill type components, identified that methane is a hazard to new home development, created a matrix that identified potential remedies and selected the preferred remedies to provide for safe development of new homes. Testing of vapors identified that the pit had accepted hydrocarbon impacted soil with  several components above threshold limits. Gary recommended that an active gas collection system be installed in the portion of the site that had high concentration of methane. Each home will need to have a geomembrane barrier with vapor collection system installed. The vapor collection system will vent through the roof similar to a plumbing vent. 

Environmental Protection Agency (EPA) | EPA R-10 Architecture and Engineering Services* | Multiple, Oregon | Technical Adviser

Gary was the technical adviser to the design engineer for the selection of a tailings pile’s cover system. He reviewed geosynthetic and soil cover systems, and determined that a soil cover system was the best system to provide long- term containment of the underling tailings.

SECONDARY PLANS

UAP Northwest | Secondary Containment* | Moses Lake, Washington | Design Engineer

Gary prepared the conceptual design of secondary containment for a fertilizer tank farm. The design constraints consisted of a 30-foot high vertical wall of lime adjacent to the containment that limited availability of land. The containment systems considered were geomembranes, soil, concrete and steel. The lowest cost system using a HDPE geomembrane was recommended.

WETLAND RESTORATION AND MITIGATION

Simpson Tacoma Kraft Company | Simpson Tacoma Kraft Mill Wetland Restoration Plan* | Tacoma, Washington | Design Engineer

STORMWATER

Emerald Kalama Chemical, LLC | Modular Tank Reconstruction* | Kalama, Washington | Project Manager / Lead Designer

Gary was the project manager and lead designer to permit a double lined containment system for the storage of storm water that has come into contact with hydrocarbons. To determine the appropriate geomembrane for the tank liner, Gary completed immersion testing of several materials and selected unsupported polypropylene as the material that reacted the least with the storm water. To maintain the maximum storage capacity in the Modutanks, he selected control density fill CDF to be installed at a slope of 0.3 percent. Using CDF instead of soil saved approximately 40 percent of the Modutank volume. Gary developed a leak detection and removal sump that prevented any penetrations in the primary geomembrane.

Emerald Kalama Chemical, LLC | Emerald Kalama On-Call T103 Testing* | Kalama, Washington | Site Assesor

LANDFILLS / SOLID WASTE

Crook County | Crook County Landfill Consulting Services* | Crook County, Washington | Landfill Engineer

Gary has been the landfill engineer for Crook County since 1995. During this time he has worked with the County to layout a systematic development of the landfill from an open pit to a sanitary landfill operation. He has developed lysimeters to measure and monitor for movement of leachate through the landfill. The condition of the cover system on previously closed portions of the landfill was question by DEQ and Gary developed a sampling program  to verify soil thickness and quality. The result of this testing program was that DEQ accepted the existing cover without any additional placement of soil over the previously closed portion of the landfill. In 2000, the first Subtitle D lined landfill cell was permitted and constructed. Gary negotiated with DEQ the requirements for the lined cell and saw the project through to construction. The landfill used a GCL in lieu of compacted clay saving the owner from having to import or bentonite amended soils. A source of locally available over-sized rock from a chip seal crushing plant was identified, this rock was used the leachate drainage layer for a cost of $8.00 per cubic yard to the owner. As the landfill is in an arid area, instead of designing a leachate pump station, we selected to use a side slope leachate collection system and remove collected leachate using a vacuum truck. This avoided bringing electrical power to the remote landfill that saved the owner over $60,000. Gary provided CQA observation and testing and prepared the construction report for the landfill development.

Josephine County | Marlsan Landfill Stormwater Diversion* | Grants Pass, Oregon | Project Manager

Gary was the project manager for the closure of an 8-acre landfill. The design extensively uses on-site soils to reduce construction cost. The cover system consists of a 30-mil PVC geomembrane and geocomposite drainage layer. Stormwater controls were developed to convey water down 2H:1V slopes and beneath the railroad tracks. Erosion control practices were incorporated into the design that included matting, PAM, check dams, temporary watering of the vegetative layer, straw waddles, and reducing the slope of ditching. As project manager, Gary provided all quality assurance reviews and of the design and ensured the design team and contractor met their agreed upon project schedule.

Maui County | Maui Central Landfill Phase IV Design Modifications* | Maui County, Hawaii | Project Manager

Gary was the project manager in the redesign of a 25-acre landfill expansion project involving a VE change proposal and design modifications. The project’s construction cost was bid at $5.4 million.

City of Port Angeles | Landfill Engineering and Environmental Services 2006 | Port Angeles, Washington | Project Manager

Gary was the project manager for the closure of the final 11 acres of the landfill and construction of a seawall. He developed contract documents for the 11-acre closure. The components included building the landfills subgrade up to 5 percent minimum slope, covering all exposed refuse, GCL, 40-mil LLDPE geomembrane, geocomposite drainage layer, and overlying soil. The use of on-site soils and compost to manufacture topsoil was used exclusively. Gary was the CQA engineer for the entire project and geosysthetic installation. The construction of the seawall first involved the excavation of over 120,000 cubic yards of refuse from a 130-foot high slope that stopped on the beach. The completed slope is one continuous 1.25 horizontal to 1 vertical slope that has withstood erosion well.  To prevent slope erosion the use of top of slope ditches and level spreaders was used. A high-end erosion control mat was used to keep the slope from eroding due to rain drop impact. The seawall is a secant wall that was installed at the toe of the bluff. The wall has a design life of 50 years. The use of precast concrete panels was used to reduce field time to pour concrete. To prevent front of wall erosion, toe armor was sized and placed. During excavation for the toe armor, a pocket of oily soil was discovered in the intertidal zone. The approach of working with Ecology’s Emergency Response Unit was selected. This allowed for Ecology to approve the approach selected with immediate implementation of the approach.

Kitsap County | Olalla Landfill RI/FS* | Olalla, Washington | Senior Engineering Consultant

Crook County | Crook County Landfill – Expansion Cell* | Crook County, Washington | QA/QC

Gary has worked with the County to lay out a systematic development of the landfill from an open pit to a sanitary landfill operation. He has developed lysimeters to measure and monitor for movement of leachate through the landfill. The condition of the cover system on previously closed portions of the landfill was question by DEQ, and Gary developed a sampling program to verify soil thickness and quality. The result of this testing program was that DEQ accepted the existing cover without any additional placement of soil over the previously closed portion of the landfill. In 2000, the first Subtitle D lined landfill cell was permitted and constructed. Gary negotiated with DEQ the requirements for the lined cell and saw the project through to construction. The landfill used a GCL in lieu of compacted clay, saving the owner from having to import or bentonite amended soils. A source of locally available oversized rock from a chip seal crushing plant was identified; this rock was used for the leachate drainage layer for   a cost of $8.00 per cubic yard to the owner. As the landfill is in an arid area, instead of designing a leachate pump station, we selected to use a side slope leachate collection system and remove collected leachate using a vacuum truck. This avoided bringing electrical power to the remote landfill and saved the owner over $60,000. Gary provided CQA observation and testing and prepared the construction report for the landfill development. In 2000, the first Subtitle D lined landfill cell was permitted and constructed. Gary negotiated with DEQ the requirements
