SB 1758 introduces statutory protections and a research pilot program concerning the operation of cement kilns and aggregate production operations situated near semiconductor wafer manufacturing facilities. The bill aims to address the growing land-use tensions between traditional heavy industrial operations and the expanding semiconductor manufacturing industry, particularly in regions like Grayson County, where both sectors are converging.
The bill creates Subchapter M in Chapter 382 of the Health and Safety Code to define key terms and establish a liability limitation for cement kiln and aggregate operators. Specifically, if these facilities are operating under a valid “new source review permit” and were active prior to the establishment of a nearby semiconductor facility, they are not liable for damages caused by seismic or vibrational disturbances to that facility. This provision is intended to protect legacy industrial operations from new litigation risks tied to emerging sensitive manufacturing technologies.
Additionally, the bill creates Subchapter M-1, which establishes a pilot program in Grayson County. The Bureau of Economic Geology at The University of Texas at Austin is tasked with conducting a scientific study of vibrational impacts associated with aggregate production near semiconductor facilities. The study must evaluate seismic data, assess the vibrational thresholds critical to semiconductor operations, and consider whether a minimum safe distance should be established between the two types of facilities. The bureau may consult with state agencies, local governments, academic institutions, and private stakeholders and may also enter into nondisclosure agreements to access proprietary data.
This bill reflects an effort to balance long-standing industrial activity with Texas’s growing high-tech economy, particularly as the state attracts semiconductor investment under national and state-level economic initiatives.
The committee substitute for Senate Bill 1758 introduces several key changes from the originally filed version, shifting the bill's focus from restrictive regulation toward a more permissive and research-focused approach. One of the most notable differences is the expansion of liability protections. While the original bill provided liability immunity solely to portland cement kiln operators, the substitute version broadens that immunity to also include aggregate production operations. This adjustment significantly widens the scope of entities shielded from lawsuits related to vibrational or seismic disturbances, provided they were operating before a nearby semiconductor wafer facility began operations.
Another major change lies in how the bill treats permitting authority during the pilot program in Grayson County. The original version imposed a temporary permitting moratorium, prohibiting the Texas Commission on Environmental Quality (TCEQ) from issuing or amending permits for cement kilns or aggregate facilities within 10 miles of a new semiconductor plant during the study period. The substitute removes this restriction, eliminating any immediate regulatory burden and signaling a more industry-friendly stance while the study is conducted.
Additionally, the language and purpose of the pilot study are refined in the substitute bill. The original bill tasked the Bureau of Economic Geology with determining whether a minimum distance greater than 10 miles is necessary to prevent disruptions to semiconductor facilities. The substitute instead frames this more flexibly, asking whether a minimum distance is necessary at all, and if so, to evaluate its basis. This change suggests a move away from a presumptive regulatory outcome and toward a more neutral, data-driven inquiry.
Overall, the Committee Substitute reflects a recalibration of the bill to protect existing industrial operations while maintaining the state's interest in supporting semiconductor development. By removing restrictive permitting provisions and broadening liability shields, the revised version prioritizes economic stability and industrial certainty while still allowing for scientific investigation into land-use compatibility.
