The ESTCP is dedicated to finding replacement for substances causing environmental andor occupational risks to health. As part of this program, each work unit is evaluated for environmental and occupational health impacts. The primary purpose of this work unit is to eliminate lead Pb from rocket and missile propellant formulations. After extensive testing, a formulation has been derived that replaces Pb with bismuth B-resorcylate, formulation RPD-540. Given the available data, the new formulation has been derived that replaces Pb with bismuth B-resorcylate, formulation RDP-540. Given the available data, the new formulation appears to be relatively environmentally benign and has a low potential to adversely affect human health and the environment. However, due to a near complete lack of experimental data for bismuth B-resorcylate, toxicity data need to be acquired prior to proceeding with finalization of this formulation. In addition, 2-nitrodiphenylamine 2-NDPA presents a potential risk to aquatic species, and an additional Microtox screen is recommended as a surrogate for aquatic toxicity tests.
