Project Updates (Christos Tsiamis, EPA Project Manager)
- Fourth Street Basin – Last fall’s pilot involved debris removal, as part of larger pilot that will be complete with the dredging and capping of the portion of the basin next to Whole Foods; right now EPA has the 50% design for that portion of the pilot and is looking to complete it in the coming months. We anticipate being out in the basin and doing work in summer, depending on the schedule. The work will involve installing bulkheads to support the dredging, then dredging the basin, removing the material, and treating it on a barge at Public Place. Once the material is stabilized, it will be sent offsite, as described in the Record of Decision (ROD). Once we’re finished dredging, we will cap that portion of the basin, which will complete cleanup for that part of the Canal.
- The First Street Basin, located adjacent to the Powerhouse property, is filled in. The ROD calls for excavation and the basin will be restored to waterway once EPA is done. We are working with the city to finish the design in the coming months; the goal is to start construction by the end of the year or early next year.
- The Powerhouse property is not part of the Superfund site but does have a PCB problem. It’s being cleaned up under the NYS Brownfields program, but EPA wants the site cleaned to levels that won’t turn it into a source of recontamination of the Canal. We will keep the CAG posted.
- The design of the entire upper Canal cleanup (RTA) involves similar aspects to the Fourth Street Basin, but is more complicated because we need to stabilize the banks so that when the dredging happens, there’s no collapse. The properties are individually owned and every bulkhead reconstruction has to be done in co-operation with the property owners. In cases where the owners are not willing to do the work, EPA will coordinate with PRPs to make sure the design and construction will be on time for all the different bulkheads north of the Fourth Street Basin and the start of dredging, in late 2018.
- EPA goals are based on what we think is a reasonable allocation of time for engineering projects; the parties we work with have different schedules, which requires lots of discussion to reconcile.
- Bulkhead restoration and reconstruction involves many legal arrangements between EPA and the owners, and EPA and PRPs. Brian Carr (EPA attorney) will describe what kind of work is involved.
