Hot-Mix Asphalt Plants - Supplying Data in Lieu of Testing

Texas allows hot-mix asphalt plants to provide data in lieu of testing when they request permits for new or relocated plants.

Under certain conditions, Texas allows hot-mix asphalt plants to provide data in lieu of testing when they request permits for new or relocated plants. The testing is otherwise required by state and federal environmental rules for HMAPs.

To help plant operators determine when and how to waive the testing, the TCEQ has prepared the following memorandum written by the TCEQ’s Engineering Services Team and Air Permits Division with input from the Association of General Contractors: Guidance for Accepting Data in Lieu of Test (DILOT) for New and Relocated Hot Mix Asphalt Plants
