[2] The plant's manager, Gordon Holk, said that contractors and other workers from O & G Industries, Ducci Electric, and Keystone Construction and Maintenance Services were at the site when the blast occurred.

[13] Middletown deputy fire marshal Al Santostefano later said that there had been fewer than 50 people injured, as some of the workers had made it out alive, and that there were no signs of life in the ruins of the plant.

[7] Emergency personnel and almost 20 ambulances were at the scene shortly after the blast occurred, using helicopters to transport victims while search-and-rescue crews with dogs[3] scoured the rubble.

[13] The mayor of Middletown said the plant will ultimately be rebuilt,[20] a statement that was confirmed by a Kleen Energy official, who said that construction would resume once the investigation into the incident was completed.

In particular, according to the local fire marshal, the investigation was to look at whether electricity was cut off from the area, whether workers had been evacuated before the purging of the gas line, and whether ignition sources were present.

[24][25] Despite the Board's interest in the case, a spokesman said on February 9 that their team of investigators was being denied entrance to the site of the explosion, on the grounds that the area was a crime scene.

[27] On August 5, 2010, the Occupational Safety and Health Administration (OSHA) announced that it planned to fine seventeen companies involved in the construction of the plant a total of $16.6 million.
