As the U.S. Environmental Protection Agency continues to sign off on new Water Infrastructure Finance and Innovation Act loans, one of its latest WIFIA approvals has a new twist.

EPA gets 51 requests seeking $6.6 billion in loans, exceeding the $6 billion agency can lend.

The U.S. Environmental Protection Agency has announced a $614-million loan to the City of San Diego for a water purification project.

Legislation, including new Water Resources Development Act, authorizes $3.7 billion for new Corps civil-works projects.

The Environmental Protection Agency has extended to July 31 an earlier July 6 deadline for states to submit a letter of interest for the second batch of funds made available through the Water Infrastructure Finance and Innovation Act.

Projects seek $2.3 billion in water-infrastructure loans, but EPA's lending capacity is $1.5 billion.
