Apollo Chemical hired a third -party consultant to assist in this evaluation and has been working closely with the City of Burlington. Through this evaluation, Apollo Chemical believes certain manufacturing processes are associated with elevated 1,4-Dioxane in wastewater. Apollo Chemical also believes that the intake water provided by the City of Burlington, at times, contains elevated 1,4-Dioxane concentrations that are passed through to Apollo Chemical's wastewater. • Apollo Chemical is currently segregating and containerizing for disposal (1) the distillate generated by certain processes and (2) the rinse/cleaning liquid used to clean the process vessels. These operational changes are believed to reduce the amount of 1,4-Dioxane in wastewater effluent. • Apollo Chemical continues to consider methods for reducing 1,4-Dioxane in the wastewater effluent. • Apollo Chemical will actively identify and minimize sources of 1,4-Dioxane in the wastewater effluent by raw material selection and process evaluations. • New product introductions will include efforts to identify possible sources of 1,4-Dioxane.
