**CANCELLED** Corrosion and Containment of Hydraulic Pipes at Ball Mountain Lake Dam in Jamaica, Vermont

There are three hydraulically operated gates located in the Intake Tower at Ball Mountain Lake Dam located in Jamaica, VT. Areas of the existing hydraulic piping, original to the dam construction, are showing signs of moderate to heavy surface corrosion and paint wear. The current hydraulic fluid in use is deemed unacceptable to be discharged into the outlet works per the EPA standards. Due to the piping corrosion present hydraulic piping will be replaced, and the current hydraulic fluid will be flushed and replaced with new environmentally acceptable liquid (EAL). The work for this project will likely include, but not be limited to, the following: a) Replacement of the original hydraulic piping with stainless steel hydraulic piping at the operating room, heating room, elevator landing level, and gate chamber. b) Complete flushing of hydraulic system and replacement of fluid with environmentally acceptable liquid (EAL) fluid. c) Partial re-routing of new hydraulic piping where required. d) Coordination of work with existing hydraulic piping containing lead paint on the surface. e) Removal and disposal of existing hydraulic fluid in accordance with local, state, and federal regulations. f) Removal and disposal of lead coated piping materials in accordance with local, state, and federal regulations. g) Minor structural modifications to the gatehouse to facilitate new hydraulic piping. h) Providing new de-humidification equipment in gate chamber room. i) Providing new sump pump equipment at gate chamber room. j) Replacing existing exhaust air louvers.
