Negative Declaration

New York City County - The City Planning Commission, as lead agency, has determined that the proposed North Riverdale Rezoning (CEQR No. 05DCP011X, ULURP No. 050043ZMX) will not have a significant adverse environmental impact. The New York City Department of City Planning, is proposing the following amendments to the Zoning Map in the northwestern Bronx neighborhood of North Riverdale, Community District 8:

The area to be rezoned is bounded by the City of Yonkers to the north, Fieldston Road, Valles Avenue and 100 feet east of Riverdale Avenue to the west, 100 feet west of Broadway to the east, and West 254th Street, Mosholu Avenue and West 256th Street to the south. The Department of City Planning proposes to rezone seventeen (17) full blocks and portions of eleven (11) blocks between north of 259th Street from R3-1 to R3A; two (2) full blocks and six (6) portions of blocks south of 259th Street and north of Mosholu Avenue from R3-2 to R3A; and six (6) full blocks and a portion of three (3) blocks south of Mosholu Avenue from R3-2 to R3-1.

The purpose of the rezoning is to maintain the current character of the neighborhood, which is primarily comprised of detached- and semi-detached homes. Due to increasing pressures in North Riverdale to redevelop underutilized lots in the rezoning area, there is an incentive to demolish existing housing stock to make way for out-of-scale attached or multifamily structures. The proposed action will limit new developments to single and two-family semi-detached and detached housing which most accurately reflects the neighborhood‘s existing pattern of development. Existing semi-detached, attached, and multifamily buildings would become legally North Riverdale Rezoning

New York City (Queens) County - The NYCDEP, as lead agency, has determined that the proposed Bowery Bay Water Pollution Control Plant, Contract 58 Improvement Program will not have a significant adverse environmental impact. The Bowery Bay Water Pollution Control Plant (WPCP) is a conventional secondary wastewater treatment plant. The existing plant has treatment facilities designed to treat an annual average dry weather flow of 150-mgd, which would produce approximately 40 dry tons per day (dtd) of dewatered sludge. The plant has hydraulic capacity to convey and to provide primary treatment for 300-mgd of wet weather flow. Currently, flows to the plant are approximately 110-mgd, while dewatered sludge production is approximately 32 dry tons per day (dtd) on an annual average basis. Existing liquid treatment operations include Raw Sewage Screening, Raw Sewage Pumping, Preliminary Settling, Activated Sludge Aeration, Final Settling and Disinfection. The solids treatment operations are composed of Gravity Thickening, Anaerobic Digestion, Sludge Storage and Centrifuge Dewatering. The dewatered sludge is hauled off-site and further processed in accordance with the Department‘s Sludge Management Program.

A Negative Declaration was given for an overall Bowery Bay WPCP improvement project (CEQR No. 96DEP163) in April 2000 concluding that the project would not result in significant environmental impacts. The construction of Phase I (Contract 57) started in December 2000. In 2003, due to financial constraints, non-critical components of the upgrade were either deferred or eliminated. The remaining activities were divided into Phases II (Contract 58) and III (Contract 59). Each phase of construction is independent of proposed subsequent phases and can be assessed for potential environmental impacts individually. The proposed project pertains to improvements for Phase 2.

The Phase II work would include the replacement of several WPCP components that would stabilize the gravity thickener facility at the Bowery Bay WPCP. Additionally, this work would include replacement of all process equipment, HVAC and electrical systems. Descriptions of the requirements for the Contract 58 General, HVAC and Electrical contracts are given below. An extension to the existing thickener gallery would be constructed to house a new Motor Control Center equipment.

Structures and Equipment Contract (58G): The structures and equipment contract would require work in multiple areas of the gravity thickener complex. The major areas of work include the gravity thickener tanks, gravity thickener gallery and the eastern side of the gallery. Work under this contract includes the following:

HVAC Contract 58H: The HVAC contract work would require installation of new heating and ventilating units and exhaust fans to provide twelve air changes per hour in the thickener gallery. Unit heaters and convectors would also be installed throughout the gallery to achieve the necessary heating requirements. The hot water supply and return would be provided from the Main Plant Boiler currently being constructed. Demolition of all existing HVAC equipment is included in the scope of work under this contract.

Electrical Contract 58E: The electrical contract work would require installation of a new 480V motor control center (MCC) to provide power and control requirements for sludge collectors, thickened sludge pumps, sludge grinders and miscellaneous processes. In addition to the new process equipment, electrical work is also required for HVAC systems, area lighting and receptacle requirements in the thickener gallery. Unit Substation E-1535 currently being constructed would be used to deliver 480V power to the new 480V MCC located on the eastside of gravity thickeners No. 6 and 8. Demolition of all existing electrical equipment is included in the scope of work under this contract. Figure A-2 shows the proposed site plan.

A preliminary critical path method (CPM) schedule was developed for the project. The estimated duration to complete all construction work is 38 months from Notice to Proceed (NTP). This project has a targeted NTP of October 2004 and a completion date of December 2007. The critical path for the project includes the work associated with lead abatement, electrical facilities and the tank-by-tank work for each thickener.

New York City (Queens) County - The NYCDEP, as lead agency, has determined that the proposed North River Water Pollution Control Plant, Contract 35 Process Optimization and Odor Minimization will not have a significant adverse environmental impact. The New York City Department of Environmental Protection (NYCDEP) is proposing improvements to the North River WPCP which would replace and upgrade miscellaneous equipment, instrumentation, and controls that are nearing the end of their useful life for the purpose of optimizing the wastewater treatment process and for the purpose of reducing potential odor generation and minimize odorous emissions.

Currently, the North River WPCP controls the odors from the wastewater treatment processes mainly through three large control systems: North Odor Control System (NOCS), South Odor Control System (SOCS) and West Odor Control System (WOCS). The air from the controlled areas undergoes two stages of treatment: the odorous air is pumped to either the NOCS, SOCS, or WOCS where it is scrubbed with a mixture of two chemicals, sodium hypochlorite and sodium hydroxide and then sent to dual-bed activated carbon adsorbers which capture odors and other compounds. The existing NOCS consists of eight (8) chemical wet scrubbers and twenty-two (22) activated carbon adsorbers and has two (2) large exhaust stacks. The SOCS consists of five (5) scrubbers and twelve (12) carbon units and has one (1) large exhaust stack. The WOCS consists of four (4) scrubbers and twelve (12) activated carbon adsorbers and the treated air of this system is sent to the NOCS plenum and exits through two identical exhaust stacks.

In addition to the existing NOCS and SOCS, there are eight (8) small carbon adsorber units that treat the odors from two (2) mixed liquor channels and one (1) small carbon adsorber that treats laboratory odors. Under the proposed action, these small carbon adsorbers would be removed and the odorous air from the mixed liquor channels would be treated by the SOCS and odorous air from laboratory would be treated by NOCS. After the completion of the proposed project, the odorous air collected and contained at the plant would be treated at either the NOCS or SOCS. The proposed modifications to the SOCS include:

To optimize the odor control process, an additional sixth process blower would be installed and modifications to the existing piping and secondary bypass system would occur.

Proposed modifications would reduce the potential for the exhaust of odorous air and other emissions at the North River WPCP by modifying and optimizing the existing odor control strategy and by containing and treating additional process areas at the plant. Because the SOCS would treat additional air from the final settling tanks effluent launders, the mixed liquor channels, and the chlorine contact tanks, the exhaust air flow rate from the SOCS would increase by approximately 42,750 cfm. The total flow from the SOCS stack would therefore increase from 171,000 cfm to 213,750 cfm upon implementation of the Contract 35 upgrades. Since the odorous air from the mixed liquor channel area would be treated by the SOCS, the eight (8) existing carbon adsorbers currently treating odors from the mixed liquor channel area would no longer be needed and would be removed under this Contract. Currently, emissions from these carbon units vent as fugitive emissions.

For the NOCS, additional standby carbon adsorbers would be installed and a small volume of laboratory air would also be treated, but this would not increase the exhaust stack flow rate, due to improvements in the duct work and ventilation patterns. Therefore, the flow rates from the NOCS stacks remain at 135, 460 cfm (per stack) under typical conditions and 222,000 cfm (per stack) at maximum flow conditions after Contract 35 upgrades.

New York City (Queens) County - The NYCDEP, as lead agency, has determined that the proposed North River Water Pollution Control Plant, Contract 2E (R) Emergency Generator Reliability Improvements will not have a significant adverse environmental impact. Currently, two (2) 3000 kVA Solar Turbine Generators serve as Emergency Generators at the North River WPCP. The generators are furnished with a diesel hydraulic starting system. The diesel engine that is mounted on the generator skid is normally provided with dc power by batteries and a battery charger. The diesel engine operates the hydraulic pump that develops high pressure to turn the main turbine. The existing battery/charger system is designed to provide a certain number of attempted starts of the diesel engine, if the turbine generator units are not started with in this number of starts, there will be no battery power available to start the turbine generator. In the event of complete loss of Con Edison power and thus ac power input to the battery charger, and to the engine generator auxiliaries it is not possible to start the existing Turbine Generators.

The work under this contract is intended to provide an emergency back-up source of ac power to the engine auxiliaries and the battery charging system, so that starting of the engine generators is not limited by the design number of starts of the battery/battery charging system. The work under this contract consists of the following:

1.  Furnishing and installing one (1) 200kW diesel generator.
2.  Furnishing and installing installation of (3) transfer switches.
3.  Furnishing and installing related conduit, wiring, testing and commissioning.
4.  Furnishing and installing structural and mechanical items of work for a complete installation.

With the installation of the work under this contract, when Con Edison power is lost, all of the auxiliaries of the solar turbine generators would be connected to the 200 kW black start generator, which would be automatically started by the transfer switches. This would provide the solar turbine generator auxiliaries with a redundant source of power to operate, while the solar turbine generators complete their starting cycle. Once the solar turbine generators begin to provide the plant with power, the solar turbine auxiliaries would be transferred back to operate from the plant power and the 200 kW diesel generator would be shut down.

New York City (Queens) County - The NYCDEP, as lead agency, has determined that the proposed Jamaica Water Pollution Control Plant, Modification Improvement Project – Phase 2 will not have a significant adverse environmental impact. On-going improvements are being made at the Jamaica WPCP as a result of a stabilization study that was conducted in 1989-1991 and 1994 to address specific operational problems to enable the Jamaica WPCP to meet its State Pollution Discharge Elimination System (SPDES) permit requirements. The New York State Department of Environmental Conservation (NYSDEC) and the NYCDEP agreed to construct various improvements throughout the Jamaica WPCP pursuant to a Consent Decree. The proposed action would enable the Jamaica WPCP to more consistently meet flow and effluent limits defined by the SPDES permit. A Negative Declaration was given for the overall Jamaica WPCP improvement project (CEQR No. 96DEP001) in May 1996 which concluded that the project would not result in significant environmental impacts. Recent modifications that have been designed for the Jamaica WPCP improvement project, and which would be funded as part of the NYCDEP‘s Fiscal Year 2004 Capital Plan, are the subject of this environmental review. The proposed project pertains to improvements and modifications of the process and odor control equipment and existing structures at the Jamaica WPCP. The improvements would also include new construction of general structures and equipment, electrical, HVAC systems, and plumbing contractor work.

The Jamaica WPCP Improvements Project Phase 2 is proposed to assist the plant in meeting permit requirements and to reduce odor impacts in the surrounding community. These goals would be obtained by increasing the reliability and efficiency of the various plant systems, reducing sludge volume, and improving sludge disposal procedures. Improvements to the facility are being implemented in phases. Phase 1 of these improvements is currently under construction.

The following specific improvements will be made under the Phase 2 improvements:

Notice Of Acceptance Of Final EIS

New York City (Brooklyn) County - The City Planning Commission, as lead agency, has accepted a Final Environmental Impact Statement on the proposed Water Street Rezoning (CEQR No. 01DCP004K, ULURP Nos. 010645 ZMK, 010646 ZSK Revised, 010647 ZSK Revised, & 030492 ZSK). The action involves a proposal by the applicant to construct a 17-story, residential building at 38-62 Water Street (Block 36, Lots 3 and part of 14) and to convert existing buildings at 64 Water Street (Block 36, part of Lot 14) and 85 Water Street (Block 26, Lot 38) to residential use. The proposed development at 38-62 Water Street would contain approximately 200 residential units, 8,300 gsf of ground-floor retail space, 8,396 gsf of community facility space, and a 327-space parking garage. Construction of the proposed building would result in the demolition of existing 1- to 4-story commercial and industrial buildings on the site, including the vacant industrial building at 54-62 Water Street which is within the D.U.M.B.O. Historic District. The proposed conversion of the vacant, 4-story industrial building at 64 Water Street would result in approximately seven residential units and 2,250 gsf of ground-floor retail space. The proposed conversion of the 4-story, former manufacturing building at 85 Water Street, which was recently converted to an interim use as a television studio, would result in three residential units and 1,112 gsf of ground-floor retail space, and the renovation and continued preservation of the building in accordance with the conditions of the special permit. It is anticipated that the projects would be completed in 2008.

In addition to the proposed project, the proposed rezoning would facilitate the redevelopment of a property located at 35-43 Front Street (Block 36, Lots 49, 52, and 53) which is not under the control of the applicant. The proposed M1-2/R8 (MX-2) zoning could result in an approximately 10-story, 90 unit residential development with about 14,760 gsf of ground-floor retail space being developed on the site. The site currently is occupied by a 3-story industrial building which would be demolished. The FEIS assumes that the site would be redeveloped by 2008.

The FEIS identifies significant adverse impacts related to hazardous materials, and archaeological and architectural resources on the applicant-owned properties at 38-62 Water Street, and identifies mitigation measures that would eliminate the potential hazardous materials and archaeological resources impacts and partially mitigate the architectural resource impact. The FEIS also identifies the potential for significant adverse impacts related to archaeological resources on the projected development site at 35-43 Front Street. Since this property is not under the control of the applicant, no practicable or feasible measures are available to mitigate this potential impact. The FEIS considers five alternatives to the proposed project: a No Action Alternative, an As-of-Right Development Alternative, an Historic Building Preservation Alternative, a M1-2/R7A (MX) Zoning Alternative and a M1-2/R6A (MX) Zoning Alternative.
