Mr. Chapman has practiced environmental engineering, civil engineering, chemical and mechanical engineering, project management and environmental science since 1981 in Texas and Alaska.  He is a co-founder of Environmental Fuel Systems, Inc. dba Chapman Engineering, which began business in fall 1988 as a partnership and incorporated in 1989.

Since co-founding the business, Mr. Chapman has:

Designed public water systems in Texas, and conducted ground-water studies for residential development in the Texas Hill Country; directed aquifer studies and pumping tests for environmental and potable water projects; directed troubleshooting and solved water quality issues in Texas public water systems;

  • Directed discharge permit preparation and wastewater system design for developments in the Texas Hill Country and along the Texas Gulf Coast;
  • Designed and oversaw development work on residential and commercial development projects, including land use planning, site grading and drainage, storm-water management, road and drainage design, lot layout, survey support, water and wastewater utility planning and design, electric, telecommunications and natural cost utility work, project cost and "pro forma" evaluation, and project management;
  • Provided "conservation development" planning, water conservation and recycling plans, drought contingency plans, resource management and policy guidance, and other planning support to developers, larger engineering firms, property managers, and ground-water conservation districts;
  • Obtained three U. S. patents in underground storage tank (UST)  leak detection and managed approximately 1,700 UST leak detection studies and accounts across the State of Texas and in other states;
  • Conducted and/or directed more than 150 Phase I and Phase II Environmental Site Assessments (ESA’s), including work under the U. S. EPA Petroleum Brownfields Grant program;
  • Conducted and/or directed work on more than 30 Texas Voluntary Cleanup Program (VCP) and Innocent Owner/Operator Program (IOP) applications and assessments from 1996 forward;
  • Conducted a voluntary environmental audit under the Texas Audit Privilege Act for a major Texas city, related mainly to the Texas solid waste rules.  This project evaluated more than 30 City-controlled properties, including water treatment plants, wastewater treatment plants, sewage lift station, material storage yards, fire department properties, and active and former PST facilities;
  • Worked on the TCEQ Drinking Water Sampling contract sampling program in 2004 and 2005, as project Quality Assurance Manager;
  • Provided project support for waste tire recycling and storage facilities in Texas and northern Mexico, working with the Border Economic Cooperation Commission (BECC) and North American Development Bank;
  • From 1992 to present, directed more than 250 "Leaking Petroleum Storage Tank" (LPST) cases under 30 Texas Administrative Code (TAC) Chapter 334, and since September 1, 2003 under the "Texas Risk Reduction Program" (TRRP) rule, 30 TAC Chapter 350;
  • Directed, performed or consulted on more than 50 risk-based corrective action, soil and ground-water assessment and/or remediation projects involving constituents ranging from petroleum hydrocarbons to halogenated hydrocarbons to heavy metals, under 30 TAC Chapter 335 and Chapter 350 ("Texas Risk Reduction Program" rule).  Project types included animal dipping vats, used oil operations, former or active dry cleaning or other industrial solvent generators, and oil and gas contaminants related to petroleum, salt water disposal, and radionuclides;
  • Prepared more than 70 Spill Prevention, Control and Countermeasure (SPCC) and/or  Facility Response Plans for petroleum bulk storage facilities;
  • Designed a number of engineered remediation systems for soil and ground-water cleanup in various Texas locations, and directed construction, startup and long-term operations of most of those systems;
  • Directed or participated in more than 100 UST removal projects;
  • Participated in numerous TCEQ rule-writing projects for soil, water, waste, storage tanks, corrosion protection, environmental laboratory operation and other issues;
  • Directed or supported project work in Texas, Louisiana, New Mexico, Oklahoma, Massachusetts, Missouri, New Hampshire, New York, Iowa, Florida, and Guam;
  • Offered expert testimony in Texas legal cases.
