Boston officials are looking to revisit safety rules after OSHA found that Laurence M. Moloney, the owner of Atlantic Coast Utilities, formed a "successor company" that is doing business in the city. On February 24 of this year, Jordy Alexander Castaneda Romero and Juan Carlos Figueroa died after being struck by a dump truck and thrown into a nine-foot-deep trench on High Street in the Financial District, where Atlantic Coast was making emergency repairs to a sewer line.

OSHA identified the successor company as Sterling Excavation LLC and said it shared responsibility with Moloney's other companies for $1.3 million the agency wants to impose for "willful, repeat and serious" workplace safety violations. OSHA also said it was inspecting Sterling Excavation after recently receiving a report about hazardous conditions at a job site in East Boston.

A spokesman for Atlantic Coast Utilities said the company is not operating as Sterling Excavation or under any other name. Nuala Nichoncubhair, who incorporated Sterling Excavation on March 1, said Moloney isn't involved with the company.

Mayoral candidate John Barros said he would ban contractors from working on public or private projects in Boston if they lie about OSHA fines or complaints on permit violations. Fellow candidate Michelle Wu said in a statement that her administration would help workers file complaints against unscrupulous contractors and establish a public database of OSHA violators.

Boston announced that its Public Works Department will deny any permit applications submitted by Moloney or companies affiliated with him.

Suffolk County District Attorney Rachel Rollins is investigating the deaths and the High Street job site. No criminal charges have been filed.
