Water Quality Standards C. List of Proposed TMDLs I. Background The New York-New Jersey Harbor (geographically defined as the Hudson River from the Tappan Zee Bridge extending out to the Outer Harbor and including the Harlem River, East River to the Throgs Neck Bridge, Jamaica Bay, Newark Bay, Hackensack River below the Oradell Dam, Passaic River below the Dundee Dam, Kill Van Kull, Arthur Kill, and the Raritan River/Bay below the Fieldville Dam) was listed by the States of New York and New Jersey under section 304(l)(1)(B) (``the short list'') of the Clean Water Act. Section 304(l)(1)(B) of the Clean Water Act (CWA) requires States to develop lists of waters entirely or substantially impacted by point source discharges of pollutants. Section 304(l) also requires States to develop individual control strategies for each point source. In order to establish individual control strategies for point sources in the Harbor, the States of New York and New Jersey and EPA joined in a cooperative effort to collect ambient and source data, develop a water quality model to assess relative loadings from all sources (municipal and industrial discharges, storm water, combined sewer overflows, sediment flux, atmospheric deposition and tributaries), and develop Total Maximum Daily Loads (TMDLs). This effort was conducted through work groups under the auspices of the New York-New Jersey Harbor Estuary Program. Due to the interstate nature of the New York-New Jersey Harbor and the desirability of consistency and equity among dischargers, the State of New Jersey requested that EPA promulgate TMDLs for the New York-New Jersey Harbor. EPA will, therefore, establish TMDLs as a federal action. Except for the Kill Van Kull and Arthur Kill, New York State has already implemented the necessary water quality-based effluent limits for waterbodies within the Harbor by issuing individual control strategies in the form of modified permits. EPA is establishing TMDLs for the remaining waterbodies for which New York State has not established TMDLs as well as Harbor waterbodies in the State of New Jersey. The EPA promulgation will result in the incorporation of TMDLs into State Water Quality Management Plans. In the State of New Jersey, this promulgation will amend the Northeast, the Lower Raritan/ Middlesex County and the Monmouth County Water Quality Management Plans. In New York State, this promulgation will amend the New York State Water Quality Management Plan. II. Tentative Determination A. Description of TMDLs The EPA is hereby issuing public notice of its intent to establish Phased TMDLs for copper, mercury, nickel and lead in New York-New Jersey Harbor. Based on ambient monitoring and/or water quality modeling efforts in New York-New Jersey Harbor, certain waterbodies within the Harbor exceed or are projected to exceed applicable water quality standards. In such cases, the Clean Water Act requires that the States calculate the maximum amount of the pollutant that the waterbody can assimilate and still meet ambient water quality standards. This amount, called the total maximum daily load, is then used to allocate loads among sources of pollutants. Loads allocated to point sources (e.g., municipal dischargers) are termed Waste Load Allocations (WLAs). Loads allocated to nonpoint sources (e.g., atmospheric inputs) are termed Load Allocations (LAs). Waterbodies within the Harbor which are known or projected to exceed applicable water quality standards and have been determined to require TMDLs are denoted by an ``X'' in Table 1. Certain waterbodies in the Harbor do not require TMDLs for all the metals of concern. For these waterbodies, no further action is being proposed. Table 1.--Waterbodies Needing TMDLs ------------------------------------------------------------------------ Waterbody Copper Mercury Nickel Lead ------------------------------------------------------------------------ Hudson River............ ..........

X X X X East R./Harlem R........ .......... X .......... .......... Jamaica Bay............. .......... X .......... .......... Raritan River/Bay....... X X X X Hackensack R./Passaic R./ Newark Bay............. X X X X ------------------------------------------------------------------------ The proposed TMDLs for copper, mercury, nickel and lead use a phased TMDL approach. For copper, nickel, and lead, the waterbodies listed in Table 1 exceed applicable water quality standards based on concentrations projected to occur by the water quality model employed for this TMDL effort. Due to the limited ambient and loading data, the state of the model calibration is uncertain for the Raritan River/Bay, the Hackensack and Passaic Rivers, and Newark Bay. Based on the available ambient data, it has been determined that existing loads are adequate to meet applicable water quality standards. The Phase I TMDLs for these waters will be based on limiting municipal and industrial point source dischargers to existing loads. Additional data collection and modeling for the Hackensack River, Passaic River, Newark Bay, Kill Van Kull, Arthur Kill, and Raritan River/Bay will be required. Once sufficient data have been collected and the water quality model has been adequately calibrated, Phase II TMDLs will be developed, adopted and implemented, as necessary, by the States of New York and New Jersey with assistance from EPA. However, if significant interstate issues arise and the Commissioners of the New York State Department of Environmental Conservation and the New Jersey Department of Environmental Protection jointly request an EPA promulgation, EPA will promulgate Phase II TMDLs for the interstate waters of New York-New Jersey Harbor. As indicated in Table 1, both ambient and model projected exceedances of mercury standards occur throughout the Harbor. Water quality modeling for mercury indicated that a significant portion of the total mercury load was not identified by the monitoring conducted to support the TMDL effort. This load, attributed to atmospheric deposition, drives exceedances of water quality standards. The proposed Phase I TMDLs for mercury are based on freezing existing point source loads and reducing atmospheric deposition loading by a portion of the anticipated levels of reduction resulting from the implementation of the Clean Air Act. Additional monitoring and water quality modeling will be conducted to: reassess the previously identified sources; quantify loads from atmospheric deposition and sediment flux; recalibrate the mercury water quality model; and to calculate Phase II TMDLs. Additional information regarding the technical development of TMDLs for the Harbor may be found in EPA's document entitled ``Total Maximum Daily Loads (TMDLs) for Copper, Mercury, Nickel and Lead in NY-NJ Harbor.'' B. Water Quality Standards States bordering interstate waters are required to assure compliance with the adjoining States' water quality standards, as well as their own. For all waters of NY-NJ Harbor, the States agreed to develop and implement Phase I TMDLs based on a uniform set of water quality criteria. The criteria, for mercury (0.025g/L), nickel (7.1 g/L) and lead (8.5 g/L) are based on the marine chronic aquatic life criterion expressed as the total recoverable form of the metal and represent the most stringent of the applicable NJ or NY standards. The copper criterion used to develop TMDLs is 5.6 g/L (expressed as dissolved metal). This value is the most stringent of the two proposed site-specific copper criteria developed (7.9 [acute] and 5.6 [chronic] g/L dissolved) for the Harbor waters (for additional information regarding the development of the site-specific copper criteria, refer to EPA's document entitled ``Development of a Site-Specific Copper Criterion for the NY/NJ Harbor Complex Using the Indicator Species Procedure''). The site-specific copper criteria will be proposed for adoption into NY and NJ State Water Quality Standards Regulations by separate State rulemaking actions. Phase I TMDL-based permit modifications will not be implemented for copper until such time as the proposed site-specific copper criteria are adopted by the States and approved by EPA. The above criteria will be applied on a Harbor-wide basis. C. Listing of Proposed Phase I TMDLs Based on applicable water quality standards and an assessment of loadings to the Harbor, Phase I TMDLs were calculated and allocated among municipal dischargers, industrial dischargers, combined sewer overflows, storm water, atmospheric, and tributaries. For copper, nickel, and lead, the Phase I TMDLs/WLAs/LAs are based on existing loads from: industrial/municipal dischargers identified as contributing significant loads of the above substances; combined sewer overflows; storm water dischargers; atmospheric deposition; and tributary sources. For mercury, Phase I TMDLs/WLAs/LAs are based on existing loads for all point sources and a projected reduction in atmospheric loads due to implementation of the Clean Air Act. Phase I TMDLs/WLAs/LAs are shown in Table 2. The TMDLs/WLAs/ LAs listed in the Tables below are not enforceable permit limits. The enforceable permit limits for municipal and industrial dischargers will be developed by the States based on the WLAs listed below. The Phase I effluent limits for municipal and industrial dischargers will be based on existing effluent quality and will be developed in accordance with ``EPA Region II's Guidance for Calculating Permit Effluent Limitations Based on Existing Effluent Quality.'' A copy of this document may be obtained by contacting the above mentioned person. The tables below identify the Phase I TMDLs/WLAs/LAs for copper, mercury, nickel, and lead in the Harbor. Additional information regarding the calculation of the TMDLs/WLAs/LAs and a listing of the individual WLA for each municipal and industrial discharger may be found in EPA's document entitled ``Total Maximum Daily Loads (TMDLs) for Copper, Mercury, Nickel and Lead in NY-NJ Harbor.''
