EPA-LEAD SERVICE LINE REPLACE

Summary
Amends the Environmental Protection Act. Provides that an owner or operator of a community water supply may, by an additional method approved by the State, give written notice of the existence of lead service lines that are connected to buildings. Provides that an owner or operator of a community water supply that performs at least 4,000 lead service line replacements per year or exceeds a statutorily prescribed lead service line replacement rate is exempt from a provision that prohibits partial lead service line replacements. Provides that, in a municipality with a population of more than 1,000,000 inhabitants, the owner of a private property upon which there is located a renter-occupied building, a building that is used as a day care, or a multi-dwelling building must allow the community water supply access to replace the lead service line on the private side of the property.
