During the week of October 30, the Gowanus Remediation Team (GRT) continued the RTA 1 Capping Operation.

Capping material was placed and graded south of Carroll Street. Sand and sealant was placed inside the Third Street Bridge monopiles. Capping material placement was completed, and preparations began for the armor layer placement. The material placement equipment was demobilized.

The next phase of the RTA 1 Capping Operation will be armor layer placement. For this work, concrete mattresses will be placed along the bed of the canal to secure the newly placed capping material. This week the GRT mobilized an excavator that will be utilized to place the mattresses. Mattresses were staged for upcoming placement.

Sealant was placed at the Butler Street and Douglass Street bulkheads.
