Be sure to tune in to the 5 p.m. and 6 p.m. newscasts on Channel 5 today. Senate Minority Leader Bruce Tarr will be providing an update on the efforts to clean up the thousands of waste filtration disks that have been washing up on many North Shore beaches since being released from a Hooksett, NH municipal wastewater treatment plant two weeks ago. The Attorney General's office has responded favorably to a request by Tarr, Essex County Sheriff Frank Cousins and several other legislators to investigate the release of these disks and to seek reimbursement from the Town of Hooksett to cover local communities' cleanup costs.
