This table is designed to give a brief description of the latest reviewed LAER controls required to meet §116.150 or §116.151 requirements for various types of equipment and process operations. Because LAER is a progressive technology standard, past determinations do not necessarily indicate current LAER. Additional information can be found in individual permit files and in letters issued by the TCEQ.
