Environmental health impact assessment (EHIA) can be defined as the systematic identification and evaluation of the potential environment health impacts or effects of oil and gas industrial projects, plans, programs, policies or legislative actions relative to the physical-chemical, biological, cultural and socioeconomic components of the total environment. EHIA is proposed for all the oil and gas industrial engineering plants for sustainable development. Total quality management (TQM) is based on quality and sustainability management from the customer’s point of view. TQM processes are divided into four sequential categories: plan, do, check, and act. This is also called the PDCA cycle for continuous process improvement. In the planning phase, oil and gas industrialists define the problem to be addressed, collect relevant data, and ascertain the problem’s root cause; in the doing phase,
