Joan shared the outfall map provided by Victoria at EPA at our request. Follow up question – how many of the outfalls are from new construction? Joan replied to ask Victoria, “How many of those outfalls, if any, are from new construction?”
We also wanted to know what Brian Carr meant by “first flush,” “second flush” when he used those terms at the General CAG meeting when discussing CSO events. Joan wrote him an email to ask.
What is the objective for the level of clean water once the canal is cleaned?
Implementation of the remedy will improve the surface water quality of the Canal by controlling and substantially eliminating sheens and preventing contact of the surface water with the contaminated sediment.
Joan sent emails to Victoria and Natalie covering a few questions – can CSO be measured at the outfalls with real-time data? Also sent email to DEC and DOH re: flood kits for basement flood testing.
Follow-ups on Action Items
1. Any acknowledgement from Fagel, Waldron or Smith to our resolution re: dissolved oxygen levels? – Erica reported – no response.
2. What is EPA’s demand for responsible parties to maintain an operation and maintenance plan (OMP) for the Gowanus Canal clean-up strategy? Who will ensure that the OMP is done going forward? Will EPA continue to check that the water quality remains good and that the cap is intact? Does EPA have an OMP Plan? Where is it? Katia followed up on these two questions – any answer? Not yet.
3. To the best of the Committee’s knowledge, neither the DEC nor NYSDOH has ever performed a comprehensive hydrology and hydrographic study for this neighborhood as the Gowanus is in a FEMA flood zone A. According to EPA, DEC is currently completing a Gowanus Canal areawide groundwater study to evaluate the current hydraulic conditions, including groundwater elevations and flow direction. This study was scheduled for completion in late 2024. Joan & Steve & then the entire CAG with an inquiry by Emily Mitchell followed up with Aaron Fischer. Aaron answered. Joan drafted a follow-up for committee review as to whether contaminant sources would be included in the report. So did Jason. I include Jason’s here because it is better.
