They started this stage of the remediation in early November 2023. Mats are inspected for cracks or defects prior to placement and divers measure the spacing between mats. They have currently laid down approximately 132,455 square feet of mats to date (approximately 75% of the total).<\/li><li>We expect mat placement to continue until March 2024, followed by subsequent material. Demobilization will occur sometime in May 2024.<\/li><li>After mat placement, grout is used to fill in the spaces between the mats. We have held off on placing grout in the top 275 feet of the canal due to a NAPL (non-aqueous phase liquid, a contaminant) issue and within 50 feet of the Carroll Street bridge until the repairs have been completed.<\/li><li>Once grout is placed at the head of the canal, the flushing tunnel will be turned back on.<\/li><li>The Trust (Gowanus Canal Environmental Remediation\u00a0Trust established\u00a0by the PRPs to perform cleanup work) has been conducting air and noise monitoring throughout. They have also been conducting movement and vibration monitoring.<\/li><li>We haven\u2019t had any major issues with dissolved oxygen (DO) since the weather cooled off. Still monitoring as significant weather events can also influence the DO.<\/li><li>NAPL sheens and <a href=\"https:\/\/www.dictionary.com\/browse\/bleb\" target=\"_blank\" rel=\"noreferrer noopener\">blebs<\/a> have been spotted near the head of the canal<ul><li>From what we see so far visually, it appears that the NAPL seems to be on the surface and that the cap is intact.<\/li><li>We don\u2019t yet have results back from the analytical samples that were taken in the vicinity to determine the source of the NAPL.<\/li><\/ul><\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">RTA2 (3rd Street to 9th Street)<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>We are working on the design for the next section of the canal (RTA2) and the 3rd\u00a0Street Bridge, 4th\u00a0Street Turning Basin, and 5th\u00a0Street Turning Basin (3\/4\/5 Area).
