REVERE – The state Ethics Commission blew the doors open Tuesday on the city’s long-simmering Public Works scandal by announcing two city workers’ bribe admissions.The commission fined Sewer Foreman Randy Adamson and Drain Foreman Anthony Giannino each $8,000 for violating state conflict of interest laws by paying bribes to General Foreman and for doing private drain laying work.The commission on Tuesday issued a show cause order alleging that Maglione sought and accepted illegal bribes and gratuities. It plans to schedule a hearing regarding the allegations involving Maglione before March.Mayor Thomas Ambrosino told the Item the three were placed on paid administrative leave Tuesday and Adamson and Giannino will face civil service hearings that could result in disciplinary action by the city.He said Maglione is presumed innocent of the commission allegations pending the outcome of the ethics hearing. Attempts to reach Giannino, Adamson and Maglione by telephone Tuesday were unsuccessful.”I’m disappointed,” Ambrosino said.The bribery case centers on the city’s policy of licensing drain layers to install and maintain pipes connecting homes and businesses to city-owned pipes.The city does not install these connection pipes; instead it maintains a list of roughly a dozen licensed private drain layers.According to the commission, Giannino and Adamson undertook about 25 of the private installation jobs between 2002 and March 2006.”Adamson and Giannino testified that Maglione approached them in 2002 and asked for $200-$250 for every new water and/or sewer service installation they performed. Between 2002 and summer 2005, they gave Maglione a total of $3,000-$4,000 regarding these installations,” the commission stated.The ethics probe has, by no means, been a local secret.In March 2006, Mayor Thomas Ambrosino wrote the commission asking if a full-time public works employee could perform private drain laying work.The commission’s response to that query was a quick and clear “no.””A municipal employee may not, directly or indirectly, receive compensation from or act as agent or attorney for anyone other than the city in connection with any particular matter in which the city is a party or has a direct and substantial interest,” the commission stated in its March 22 letter citing the state conflict of interest law.Ambrosino informed the council a week after receiving the commission opinion that full-time city workers would not be allowed to lay drains.Adamson was recently disciplined by the city on a matter unrelated to the drain laying investigation. Ambrosino informed the City Council last month that the city and the municipal union representing Public Works employees had signed settlement agreements prescribing two-day suspensions without pay for Adamson for using a city vehicle for personal use on Sept. 21, 2007.
