After armed federal agents entered a warehouse owned by the Puerto Rico Electric Power Authority, known as PREPA, on January 6, they said the warehouse had contained rebuilding materials that they seized to distribute on the island. The Intercept’s report on the incident has led to calls on the island for criminal prosecutions of PREPA officials, with the governor referring the matter to the Department of Justice.

“PREPA affirms that the [U.S. Army Corps of Engineers] and their contractors have had access to them since before the alleged discovery,” Gov. Ricardo Rosselló wrote in the statement asking the Department of Justice to investigate the matter. “Therefore, we are referring the matter to the Department of Justice in order to analyze the facts and determine whether there was a commission of crimes or negligent action.”

In a statement issued Wednesday night, Puerto Rico Senate minority leader Eduardo Bhatia said, “Lying about not having the parts to cover the inefficiency of PREPA is outrageous and those responsible must be taken before state and federal authorities to be criminally processed immediately.”

But PREPA isn’t the only player involved in the island’s grid restoration efforts with a cache of materials. Photos sent to The Intercept from UTIER, the electric utility workers’ union in Puerto Rico, show another store of materials — many of them more recently acquired and potentially immediately useful to rebuilding efforts — at a warehouse in Ponce controlled by the USACE itself.

Stored at the Ponce warehouse are concrete and metal poles used to erect power lines, as well as a large quantity of electrical wires of varying sizes and cross arms “in vast quantities,” Fredyson Martinez, UTIER’s vice president, told me by phone on Thursday. There are also several shipping containers, the contents of which are unknown. All of the materials shown, he noted, “are critical in the recovery effort that PREPA workers and contractors are doing to restore the power grid.”

“That is not normal to have such quantities of materials in the crisis that we are having in Puerto Rico. For example, I have never seen such quantity of cross arms in my life,” Martinez said, “The amount of [containers of wires] is also too much knowing what is needed. And all that just sitting there while the workers make miracles with the few things they get each day. It’s sad.”

“USACE is accusing PREPA of doing something that they are doing on a larger scale. They’re mostly just punching back,” he said, referencing ongoing criticisms from UTIER and others on the island of USACE’s work there.

Asked about the photos and why materials had not been distributed out to linemen, USACE spokesperson Luciano Vera said, “Ponce is one of our main distribution points for materials. We have multiple barges arriving weekly with containers of cable, poles, and other materials. As the thousands of pieces of materials arrive to the port, they are distributed to work sites throughout the island and to one of our distribution points for future use. With the increase of materials arriving to the island, we have increased storage capacity, and contractors are able request materials from one of our distribution points for upcoming work sites.”

USACE for most of its time working in Puerto Rico post-Hurricane Maria has had two warehouses, one in the capital, San Juan, and another in Ponce, on the south end of the island. USACE recently began using another warehouse in Bayamon, but line workers have been consistently frustrated with the pace of recovery rooted partially — according to UTIER — in the amount of time it takes to transfer materials from USACE’s two, and now three, warehouses to job sites around the island. “USACE is looking at other options as well, as capacity increases,” Vera said in an email.
