Local prosecutors in Sakhalin are reportedly investigating a pipeline spill that occurred last week at a Rosneft operated site on the island of Sakhalin.
According to Reuters, Rosneft said an idled pipeline on the Pacific island of Sakhalin spilled about 110 barrels, or about 15 tonnes, of oil on Wednesday.
The spill occurred at the Ekhabi field as work was being performed on the idled line, RT said.
The field is operated by Rosneft subsidiary RN-Sakhalinmorneftegaz.
Russian environmental regulator Rosprirodnadzor told TASS last Thursday that preliminary data showed the spill affected an area of about 3,500 square meters and did not impact any nearby water bodies.
The regulator added that part of the spill was intentionally ignited after it was discovered to help mitigate damage at the site.
However, the regulator warned that the some of the released oil could make its way into nearby water bodies if melting snow raises water levels.
Local environmental watchdogs have claimed the spill is much larger than Rosneft’s estimates suggest.
Dmitry Lisitsin, a local activist in Sakhalin, told Reuters the spill may be as large as 300 tonnes.
Sakhalin’s public prosecutors office will be investigating Rosneft’s response to the accident and a special commission will be convened to determine the size of the spill’s impact, RT added.
