|(a) Applicability. This subchapter applies to any structure or vessel in or on coastal waters, on public or private lands or at a public or private port or dock if the structure or vessel is in a wrecked, derelict, or substantially dismantled condition. (b) Purpose. There has been an increase in the number of derelict and abandoned vessels that are either grounded or anchored upon publicly or privately owned submerged lands. These vessels are public nuisances and safety hazards as they often pose hazards to navigation, detract from the aesthetics of Texas coastal waterways, and threaten the environment with the potential release of oil and hazardous substances. The costs associated with the disposal of derelict and abandoned vessels are substantial, and in many cases there is no way to track down the current vessel owners in order to seek compensation. As a result, the costs associated with the removal of derelict vessels becomes a burden on public entities and the taxpaying public. This subchapter is adopted to implement H.B 2096 (Acts 2005, 79th Legislature, Chapter 216, effective September 1, 2005) and H.B. 3306 (Acts 2009, 81st Legislature, Chapter 1324, effective September 1, 2009).
