These settling basins were designed by TM Engineering in 2003 and are regulated by the Maryland Dam Safety agency. The primary purpose of these earth dams, with a height of 20.5 feet and a length of 1000 feet, is flood risk reduction, serving to protect the surrounding area from potential inundation.
Constructed in 1960, the Cristal Global Hawkins Point Plant Settling Basins have a storage capacity of 104 acre-feet and are situated offstream from the Patapsco River. Although their hazard potential is rated as low, the risk assessment for these structures is classified as very high. Despite not having a condition assessment rating, these settling basins undergo inspections every 5 years, with the last inspection conducted in April 2014. While no emergency action plan details are provided, these basins are essential components of the flood risk reduction infrastructure in the area, highlighting the intersection of water resource management and climate resilience in the region.
