REVERE – City Councilors say the ongoing probe into Public Works Department operations should be expanded to include an investigation into the residency status of department workers.Ward 4 City Councilor George Rotondo, who has led the more than year long probe into the department, wants the council to review bills and other documents proving public works employees live in the city.Councilor at Large John Correggio wants the review of the city?s live-where-you-work policy expanded to include a provision requiring city department heads to prove they are city residents before they accept an appointment to a city job.?It?s time to require future department heads to reside in Revere before they move to the city,” Correggio said.The pair plan to submit motions to the council on July 28 outlining their proposals.Two state agencies are probing DPW operations with the state auditor reviewing inventory records and other paperwork and the Ethics Commission expected to rule on conflict of interest charges by month?s end.The charges center on Commission accusations that city general foreman Joseph Maglione solicited and accepted bribes from former city Public Works department employees Randy Adamson and Anthony Giannino.Prior to paying fines and resigning last year, the pair admitted to paying $200 bribes to Maglione for each of the 25 private drain line jobs they performed. Adamson and Giannino were not licensed to perform the work.William Spallina, Maglione?s attorney, says his client is innocent.Rotondo testified during the winter before the commission, saying in response to a question, that DPW Superintendent Donald Goodwin should be fired.Rotondo has called during council sessions for probes into department inventory control and outside reviews of its management.
