EAST RIVER STUDY
Issues concerning the Newtown Creek Upgrade/East River Water Quality Plan
that NYCDEP’s consultants have addressed in further detail as part of this study
include:
- Various location, capacity and treatment level alternatives to the
Newtown Creek upgrade;
- Alternatives for reducing the water quality impacts of nitrogen
discharged by East River WPCP’s, including both treatment and
non-treatment-based approaches, and
- Additional WPCP facilities planning issues including WPCP
treatment capacity and combined sewer overflow (CSO)
conveyance capacity.
Water quality models were developed for use in evaluating various
alternatives.
Revised Consent Orders for the Newtown Creek upgrade and a new
Consent Order addressing nitrogen control requirements have been signed.
Additional environmental assessment work related to the Newtown Creek
WPCP 3 facility upgrade alternative is underway. Task reports for most
project tasks have been completed and finalized. The conceptual design of
the recommended plan is described in the Task 13 Conceptual Design
report. The final project remains to be completed.
The attached Table 1 shows specific East River Water Quality Plaiming
project tasks and their status as of June 2002.
