City Planning Commission Discusses Environmental Impact of New Sewer Disinfection Facilities in Flushing Creek



The City Planning Commission (CPC) held a session on October 6 to discuss the environmental impact of two proposed disinfection facilities for combined sewer overflows (CSOs) in Flushing Creek, Queens. Concerns over water quality degradations from CSOs prompted this development, which aims to address long-standing pollution issues in the area.

The Department of Environmental Protection (DEP) informed the commission that the project aligns with a previously established consent order designed to enhance water quality along Flushing Creek. Construction will include a dechlorination facility at the southern site, known as TI 10, and a chlorination facility at the northern location, TI 11. Both facilities aim to eliminate pathogens in the water before it discharges back into the creek (Source: https://youtu.be/3enUsCW5tCg&t=871).

Participants expressed skepticism about the efficacy of these developments in combatting pollution. Community concerns centered around whether the proposed solutions would adequately mitigate negative impacts on surrounding populations and ecosystems. Testimonies highlighted apprehensions regarding increased stormwater runoff and its implications for local flood management, particularly in the light of predicted rainfall increases due to climate change (Source: https://youtu.be/3enUsCW5tCg&t=1303).

The proposed facilities are designed to operate predominantly during the wet season, active from May 1 to October 31, which corresponds to periods of considerable rainfall. DEP officials noted that the facilities are expected to significantly reduce the volume of CSO discharges from Flushing Creek by managing over 1 billion gallons per day during peak overflow periods (Source: https://youtu.be/3enUsCW5tCg&t=871).

Concerns about infrastructure were also raised, particularly regarding the adequacy of existing waste management and drainage systems to handle increased demand stemming from new developments. Residents demanded rigorous analysis and transparency regarding how these facilities would interact with current sewage systems, which are historically overwhelmed during heavy storms (Source: https://youtu.be/3enUsCW5tCg&t=1303).

The commission acknowledged that the projects aim to enhance local water quality but reiterated the importance of community engagement and the necessity for ongoing dialogue about environmental resilience. Past conversations highlighted this need, alongside the requirement for developments to comply with stormwater management regulations which prioritize green infrastructure (Source: https://getlocalpost.com/2025/01/06/planning-for-the-future-city-commission-discusses-monitoring-infrastructure-impacts-of-increased-housing-density/).

As the CPC reviews this project, ensuring that it benefits both water quality and the surrounding communities remains paramount, as balancing development with environmental stewardship will be critical for the community’s long-term health and sustainability.
