Environmental Chemist/Regulatory Specialist


With previous experience working as a regulator for the Texas Commission on Environmental Quality (TCEQ), an environmental manager for an industrial facility, and a project manager for an engineering consulting firm, Gail Corrigan formed Corrigan Consulting, Inc. in May 1986. Ms. Corrigan now has over 20 years of experience and is well known in Texas for her hazardous waste regulatory expertise. Under contract with Texas A&M University Engineering Extension Services, she developed and instructed two Hazardous Waste Management Courses on a monthly basis throughout Texas for five years. Ms. Corrigan has directed the company in completing over 500 projects for a wide variety of clients, providing quality control to ensure client satisfaction and setting the management philosophy to ensure a good work environment for our staff.

 

She has directed a wide variety of site investigations and remedial actions at industrial, commercial and Superfund sites. She has directed and provided litigation support on hundreds of Environmental Site Assessments (ESAs) and serves on the ASTM E-50 Committee on developing the ESA Standards. She assisted the City of Houston to develop a specialized ESA standard for infrastructure work and has developed a standard format for conducting ESAs of linear projects for Houston METRO. Ms. Corrigan has also directed NEPA environmental analyses in support of many projects funded by local, state and federal government agencies.

 

In 1985, Ms. Corrigan founded the Texas Hazardous Waste Management Society, and served as the President during the first year, growing the organization to over 400 members. She continued to serve on the Board of Directors from 1986 to 1990. In 1993 to 1994, Ms. Corrigan served on the Professional Certification Task Force for the Hazardous Waste Action Coalition (HWAC), a coalition of the American Consulting Engineers Council (ACEC).

Gary L. Kratochvil, P.G., CAPM

back to top

Senior Associate


Mr. Kratochvil has more than 30 years of professional experience including 20 years in geology, hydrogeology, and environmental consulting. He specializes in RCRA and CERCLA corrective action projects and has managed or directly conducted numerous RCRA Facility Investigations (RFIs)/Affected Property Assessments and Reports (APARS) under the Texas Risk Reduction Program (TRRP), Corrective Measures Investigations (CMIs), and Risk-based Closures. He has also prepared RCRA Groundwater Compliance Plans and Hazardous Waste Permit Applications and conducted Phase II Environmental Site Assessments. He has implemented remedial actions at CERCLA and RCRA facilities including petroleum refinery and chemical plants and at Superfund sites. His experience in conducting environmental investigations and remedial activities and risk-based closures has included commercial, industrial, and government clients.

 

Recent RCRA corrective action projects have involved statistical determination of site-specific background concentrations for constituents of concern and both simple and stratified-random sampling protocols. Cone Penetrometer Test and expedited direct-push sampling programs are typically used to develop conceptual stratigraphic models to guide extensive groundwater investigations involving DNAPL, heavy metals, and petroleum hydrocarbon constituents. Interim corrective measures have also been implemented at several locations to establish hydraulic control of groundwater plumes and mitigate potential off-site migration. On-going TRRP projects require constant monitoring of new TCEQ guidance documents.

 

Prior to environmental consulting, Mr. Kratochvil was a Lieutenant Colonel in the U.S. Army where he served as Associate Professor of Geology at the U.S. Military Academy at West Point. He has also served as Science Advisor to NASA’s Corps of Astronauts at the Johnson Space Center. He has a distinguished list of publications in the field of geology from 1978 to 1996.
