Four classes of phthalates would be designated as priority chemicals under newly issued proposed regulations by the Maine Department of Environmental Protection (DEP). Di92-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), benzyl butyl phthalate (BBP) and diethyl phthalate (DEP) would all be listed as priority chemicals and reporting requirements would be put in place on manufacturers of household cleaning products that contain one or more of the phthalates. The DEP will hold a public hearing on the proposed rule on July 29, and comments are due on September 29, 2014.

In March, the DEP proposed a rule that would list cadmium, arsenic, mercury and formaldehyde as priority chemicals.
