33 (a) Any person owning or operating a source which emits air contaminants into the air of this state shall, upon request by the Texas Natural Resource Conservation Commission (TNRCC or Commission) or the Executive Director, conduct sampling to determine the opacity, rate, composition, and/or concentration of such emissions.
