Tisbury selectmen and town officials took stock in the aftermath of a Monday oil spill at Lake Tashmoo Tuesday night, praising the response to the sunken sport fishing boat.

“It was a challenging day, no question about it, but we had great team response, we effected some positive outcomes with the resources we had there,” fire chief John Schilling told selectmen at their regular meeting Tuesday.. “I’m very pleased and the town should be about what was accomplished there yesterday.”

The 33-foot boat sank in the Bishop’s Cove area of Tashmoo sometime late Sunday night or early Monday morning. A report of a spill of diesel fuel came in the morning, Mr. Schilling said, and multiple town agencies responded, including the department of public works, shellfish department, harbor department, police department, and fire department. The Coast Guard sent an oil spill response team from Otis Air Force Base in Hyannis. The Department of Environmental Protection was also on the scene.

Shellfish constable Danielle Ewart said that the Division of Marine Fisheries would be coming next week to assess Tashmoo. Until then, she said, the pond is closed to shellfishing.

“It’s not exactly known how much spilled, but it doesn’t take a lot on water to look pretty dramatic, and we had an extensive rainbow sheen,” Mr. Schilling said.

“It’s a lot, but it could have been a lot worse,” selectman and board chairman Jonathan Snyder said. It is estimated that about 20 gallons of diesel fuel leaked from the boat. There were 150 gallons on board.

Mr. Schilling said the first response came from commercial fishermen at the Lake street landing, who deployed a boom stored at the docks.

“Those were put out immediately; they did catch some of the product,” he said. The fire department and harbor department deployed 1,000 feet of a boom from the town oil spill response trailer, which is provided to each town in southeastern Massachusetts by the DEP. Ms. Ewart spread absorbent pads along the north and south sides of the Lake street dock.

“Those pads did a wonderful job,” Mr. Schilling said. “In fact, the DEP complimented us today when we were cleaning the pads up [about] how much product was taken off the shoreline.”

A boom was put in place around the sunken boat. The boat was not removed until Tuesday when a crew led by John Packer worked on salvage.

Mr. Schilling said that crews from the DEP and the Coast Guard were both on hand to observe the salvage and cleanup efforts.

“They were very satisfied with everything that took place today [Tuesday],” he said. The DEP will restock the oil spill response trailer at no cost to the town, and will provide Tisbury with a formal report on the spill.

“Once we get that we’ll get together with all the agencies and review our response and everything we can learn from that, and we’ll move forward,” Mr. Schilling said.

He praised the local effort, particularly that of volunteer firefighter Richard Clark, who is also a terminal agent with the Steamship Authority. Mr. Clark has received oil spill training through the Steamship Authority and was “a big asset” to the overall response, the chief said.

Mr. Schilling also thanked Cumberland Farms for bringing hot chocolate to the crews, and Stop & Shop for sending up sandwiches.

“Nobody likes to have something like this happen, especially to such a wonderful resource,” selectman Melinda Loberg said. “It’s heartbreaking to think about the possible damage, but I think our town departments and volunteers, people from the community . . . they pulled together and put their heads together and figured out how to manage this. We’re not a rich town and we don’t have all the resources in the world, but we used the ones we have to very good effect.”

Mrs. Loberg said the town should replenish the supply of response materials at Lake street that the commercial fishermen had put in place.

“And we can practice using it from time to time,” she said. “I think that’s a good idea.”

“I don’t remember seeing a drill conducted down there in the last five years,” Mr. Snyder said.

The last oil spill response drill in Tisbury took place in the outer Vineyard Haven harbor and was intended to test strategies for protecting Lagoon Pond.

“Should there be a spill in the outer harbor, you know — how would we handle the strong currents that run through there, and what type of deployment tactics for the boom would we use there?” Mr. Schilling said. Shellfish, harbor, fire and DEP officials participated in that drill.

“That was where our last training was,” Mr. Schilling said. “We didn’t do anything for Tashmoo, and hadn’t done anything in Tashmoo — but we did yesterday.”
