Relating to the operation of a cement kiln and the production of aggregates near a semiconductor wafer manufacturing facility.

SB 1758 creates a legal exemption for cement kilns and aggregate production facilities that began operations before nearby semiconductor wafer manufacturing plants. Specifically, it states that owners/operators of such pre-existing cement/aggregate facilities cannot be held liable for vibration damage to semiconductor facilities caused by their operations, provided the cement/aggregate facility started before the semiconductor plant. The bill also establishes a two-year pilot program in Grayson County (ending in 2027) to study vibration impacts, managed by the University of Texas Bureau of Economic Geology. This directly affects semiconductor manufacturers and cement/aggregate operators in areas where these facilities operate near each other. The law applies statewide but includes a limited pilot program for Grayson County.
