He has served as Project Director/Manager for hundreds of environmental assessments, property cleanups, and regulatory closures for all facets of public and private-sector clients. Scott has unique in-depth knowledge of community redevelopment programs and property redevelopment strategies especially as they relate to Brownfields types of properties.

Following three years of initial studies in chemical engineering at Texas A&M University, Scott entered the US Navy Nuclear Power program in 1984. He subsequently served for four years as a navy instructor at the naval nuclear power plant prototype facility at the Idaho National Engineering Laboratory in Idaho Falls, Idaho. His follow-on four-year tour was aboard the USS Gurnard, SSN 622 fast attack nuclear submarine home ported in San Diego, California. As a Non-Commission Officer, Scott served as the lead chemist and radiological controls/radiation health physics supervisor, as well as a nuclear power/propulsion plant supervisor. He was awarded the Navy Achievement Medal for his distinguished service and received an Honorable Discharge in 1992.

Following his naval service, Scott joined International Technology Corporation in the Groundwater Services Division in Houston, Texas. His responsibilities included assisting in the design, installation, operation, and maintenance of soil-vapor extraction and vacuum-enhanced pumping, total fluids, and skimming groundwater remediation systems throughout the US. In 1993 Mr. Leafe was recruited by Carter & Burgess, Inc (C&B) and was rapidly promoted to Project Manager in the Houston Environmental Services Division. Mr. Leafe became extensively involved in community redevelopment efforts within the City of Houston and developed specific expertise in assessment and return-to-re-use of environmentally impaired commercial and industrial properties. Mr. Leafe developed pro forma estimating methodologies that allowed for expedited site assessment, property acquisition, and site redevelopment while still maintaining cost efficiency and timely project completion. In 2000, Mr. Leafe was promoted to Associate by the Board of Directors of C&B.

Building on his vision to provide timely and high-quality environmental services to a wide-variety of private and governmental clients and to further expand his capabilities in the area of Brownfields redevelopment, Mr. Leafe formed SKA in June of 2001. Since its inception, SKA has become renowned for its superior service and quality and for its ability to provide real-world solutions to complex environmental challenges.

Mike Schultz, P.E., CAPM, Vice President/Partner

Mr. Schultz is a Vice President and Partner of SKA having joined the firm in 2004. He has over 27 years of environmental experience, including 22 years in environmental consulting, widely ranging from large-scale Superfund and surface mining facilities to retail petroleum properties and due diligence.

Mike spent the first 5 years of his career involved in environmental permitting studies for surface mining operations. Initially he was on staff with the Railroad Commission of Texas, Surface Mining and Reclamation Division for about two years, and then joined Hall Southwest Corporation in Austin, Texas as a private consultant conducting baseline studies for proposed and existing mining operations. These studies included overburden characterization, hydrogeologic and surface water hydrologic investigations, climatological studies, alternative water supply investigations, modeling for estimation of the probable hydrologic consequences of mining, and permitting services for water rights permits, wastewater discharge permits, and levee permits. While at Hall Southwest Mike also developed extensive experience in the assessment and remediation of PCBs and spent two years managing a PCB and oil spill emergency response contract for the City of Austin Electric Utility Department. Under this contract crews were on call 24/7 to remediate PCB and oil spill sites in commercial, industrial, and residential areas. More than 150 spill sites were remediated under this contract.

In 1994 Hall Southwest was sold to Groundwater Technology, Inc. (GTI) and Mr. Schultz moved to Houston, Texas as GTI’s Houston Operations Manager. During his tenure with GTI, Mike developed particular expertise in the assessment and remediation of sites impacted by petroleum hydrocarbons and chlorinated solvents in soil and groundwater. His expertise included the design and implementation of a number of groundwater remediation systems as well as implementing monitored natural attenuation remedial strategies for groundwater contaminant plumes. A number of the chlorinated solvent sites were dry cleaning facilities. Mike also developed a particular expertise for inspecting and assessing dry cleaning facilities for poor waste management practices and environmental releases.

Mike joined Carter & Burgess, Inc. (C&B) in 1998 as a Senior Project Manager and continued to develop his expertise in site assessment and remediation and added Brownfields redevelopment assessments/cleanups to his portfolio of experience. Mike accepted a Senior Project Manager position with MFG, Inc. in 2001 and became heavily involved in federal and state Superfund projects along the Gulf Coast and at a former mineral processing facility in East St Louis, Illinois. He managed two Remedial Investigation/Feasibility Study projects and a Post Remedial Action Evaluation project.

Throughout his private consulting career, Mr. Schultz has also provided litigation support and served as an expert witness in a number of legal cases to include deposition and trial testimony in State and Federal court. These cases have often involved the source and extent of contamination and likely cleanup costs, and have dealt with individual sites and class actions.

Mike brought his entrepreneurial vision and extensive technical and management experience to SKA in 2004 as Operations Manager. Mike became a Vice President of SKA in 2008 and a Partner in January 2009.

Mike is a 1985 graduate of the Colorado School of Mines with a B.S. in Mining Engineering.
