Amend HB 2912 on third reading by striking Section 5.2291(a), Water Code, as added by the Lewis amendment, and substituting the following: (a) In this section, "scientific and technical environmental services" means services, other than engineering services, of a scientific or technical nature the conduct of which requires technical training and professional judgment. The term includes modeling, risk assessment, site characterization and assessment, studies of the magnitude, source, and extent of contamination, contaminant fate and transport analysis, watershed assessment and analysis, total maximum daily load studies, scientific data analysis, and similar tasks, to the extent those tasks are not defined as the "practice of engineering" under the Texas Engineering Practice Act (Article 3271a, Vernon's Texas Civil Statutes).
