"The location of this pipe was included in reference materials in the contract," said WSDOT.
"However, contractor Seattle Tunnel Partners said the pipe's location came as "a surprise." The contractor claimed Department of Ecology rules require that such pipes be removed upon decommission of wells.
"But a spokesperson for the department said rules only require that casings for decommissioned wells are properly perforated and filled.
“There is no rule that [says] all well casings have to be removed.
"Both WSDOT officials and the contractor declined to elaborate."
In addition to the pipe, test borings suggest other objects, not yet within view, may be contributing to the blockage. Crews have only examined the top 15 feet of a hole nearly 60 feet deep.
