Edgartown wastewater commissioners outlined a new billing system this week aimed at ironing out accounting issues that led to a fraud investigation by the Cape and Islands district attorney earlier this year.

Tim Connelly, wastewater commissioner chairman, told the selectmen at their weekly meeting on Monday the changes recommended by the town’s independent auditor have been adopted. Changes include new accounting software, separation of billing and collection and a new system to measure waste deposited at the plant by private haulers.

Park-and-Ride Theft

Tisbury police are investigating a weekend break-in at the Park-and-Ride lot on High Point Lane where an electrician’s van was vandalized and a large quantity of tools stolen. Tisbury police chief Dan Hanavan said on Thursday that he believes the incident is unrelated to an earlier incident where some youths were apprehended for stealing cars and joyriding at the same parking lot. “We had a couple of kids taking joyrides up there, but we don’t think it is related to this break-in,” the chief said.

Acquitted on Assault

A wheelchair-bound Vineyard Haven man was acquitted this week of a charge he used a baseball bat to assault a man he accused of molesting a three-year-old girl.

After a bench trial in Edgartown district court on Monday, Francis C. Hebert, 57, owner of Mac PC Sales and Service, was found not guilty of assault and battery with a dangerous weapon stemming from a Feb. 22 arrest.

Sengekontacket Algae

The algae cochlodinium has been spotted in Sengekontacket Pond, Vineyard marine biologists confirmed last week.

The Tri-Town Ambulance Service has a new chief, new medics and soon will have a new intermunicipal agreement among the three towns it serves.

Aquinnah, Chilmark and West Tisbury selectmen met on Wednesday to begin discussing changes to the 35-year-old ambulance service agreement and assessment formula.

West Tisbury selectman Richard Knabel, who led the effort to draft a new agreement over the summer, said there were two major issues — governance structure and dividing assessments and revenues among the towns.

Vineyard towns lost out on vital community block grant funding for this year, but will be eligible to apply again next year, after the Massachusetts Department of Housing and Community Development decided to forgo an every-other-year funding model last month.

The housing department eliminated the alternate year funding proposal from its 2012 action plan after a public hearing in August. Instead the department will limit the maximum amount of funding over a two-year period to $1.35 million per town.
