Requires DOT to conduct study and issue report on use of rock salt on roadways.

This bill requires New Jersey's Department of Transportation (DOT) to study rock salt usage for road de-icing and submit a report to the Governor and Legislature within one year. The study must cover the DOT's past decade of rock salt use (including costs), efforts to reduce it (like temperature sensors and tracking systems), and how salt affects water quality, aquatic life, and public health. It also analyzes current alternatives to rock salt and evaluates feasible future options, including their environmental and financial impacts. The report will directly inform state decisions about road maintenance practices and potential policy changes.
