A push to have the public vote on a plan to consolidate emergency dispatch services in Bangor took another step forward today. Bangor police dispatcher Jim Morrill is behind an effort to overturn a city council decision to combine the city’s dispatch with Penobscot County Regional Dispatch. He had to collect about 2,200 signatures to put the issue to a citywide vote. City Clerk Patti Dubois says Morrill turned in more than 2,100 signatures today, on top of the 600 previously submitted. The clerk’s office now has 20 days to verify the signatures. Dubois says if at least 2,236 are valid, the city council will have to schedule a vote on the consolidation plan. Councilors approved combining services, saying the city’s basically been double-billed for emergency dispatch by paying both Bangor Police and Penobscot County.
