The 76 Federally approved water quality classifications and criteria of this Area have been summarized in tables with a standardized format using the following fourteen criteria: floating solids, settleable solids, sludge de- posits, solid refuse, sewage, oil, coliform density, pH, dissolved oxygen, color, turbidity, taste, toxic wastes, and temperature. The locations of these classes of water quality are depicted on 29 maps. The coded interstate streams, water bodies, assigned classes and class change- points are shown in red, and the intrastate streams and culture are shown in black. INTRODUCTION Legislative Authority for Interstate Water Quality Standards The Water Quality Act of 1965, Public Law 89-234, included provisions for the establishment of water quality standards for "interstate waters."—^ This Act gave the States the option of preparing water quality standards for their interstate waters or having the Federal Government prepare the standards. T/ The term "interstate waters," as defined by the Water Quality Act of 1965, means all rivers, lakes, and other waters that flow across or form a part of State boundaries, including coastal waters. For an expanded definition-of in- terstate waters as applied to water quality standards refer to Appendix I. ------- The Act provided that the State submissions would become the Federal standards for interstate waters within a State if: 1. The Governor or State water pollution control agency filed, by October 2, 1966, a letter of intent that the State, after public hearings, would before June 30, 1967, adopt (a) water quality criteria applicable to interstate waters or portions thereof within the State, and (b) a plan for the implementation and en- forcement of the criteria, 2. The State subsequently adopted such criteria and plan, and 3. The Secretary of the Interior determined that the State criteria and plan were consistent with the purposes of the Act, i.e.,— " to enhance the quality and value of our water resources and to establish a national policy for the prevention, control, and abatement of water pollution." Submission of Water Quality Standards to the Secretary of the Interior Each State's submission of water quality standards contained three in- tegral parts, (1) classifications of water bodies according to the best us- age to be made of a particular body of water, (2) water quality criteria that describe the limits of the physical, chemical and biochemical characteristics of the water for this best usage, and (3) an implementation plan of water pol- lution control facilities construction to achieve the desired water quality. In the Northeast, many of the State agencies concerned with the quality of surface waters have long recognized the necessity of protecting this vital resource and had programs for the establishment of water quality objectives before the enactment of the Federal Water Quality Act. Water quality stand- ards for most interstate streams in the Hudson-Delaware Basins Area have been - 2 - ------- submitted by the States and have been approved, wholly or conditionally, by the Secretary of the Interior. The standards for a few Interstate water bodies In Vermont, including the Rock River, Missisquoi River, Lake Metnphre- magog, and the Coaticook River, have not been adopted by the State. Water quality classifications and standards will be modified when needed, after State public hearings have been held and the Secretary of the Interior approves the modifications. In a few cases, the stream classification as- signed by one State is different from that of an adjoining State; these dif- ferences are to be resolved. In addition, hearings have been held on the re- vision of the thermal criteria in the water quality standards of several ti- dal waters. The water quality classifications and criteria in this Atlas have been accepted by the Secretary of the Interior and are correct as of the date of publication. Purpose and Scope of This Atlas This Atlas is intended to be a quick reference for locating the classi- fication and determining the water use and water quality criteria for all significant interstate water bodies within the Hudson-Delaware Basins Area. For this purpose, the Federally approved water quality classifications of interstate streams are shown on a series of page size schematic maps. The water quality criteria for each of these classifications are summarized In tables with the standardized format. Each designated classification with its associated water quality criteria represents the best uses of that water body as recommended by the respective State or interstate water pollution control agency. In some reaches and areas the existing water quality may be below the criteria of the assigned classifi- - 3 - ------- cation due to existing polluting discharges. The implementation plan of waste water control facilities construction to achieve the desired water quality in these interstate streams is beyond the scope of this report. With the passage of time, there will be modifications made to the water quality classifications and criteria. For interstate water bodies, these changes will be initiated by the State water pollution control agency and approved by the Secretary of the Interior. When these revisions are offi- cially Federally approved, addenda will be issued to make the appropriate changes in this Water Quality Atlas. HAPS The area encompassed by this Atlas is shown in Figure HD-1. Because this area extends from Cape May, N. J., to the Canadian Border, only a few interstate water bodies can be distinguished on the page sized map. To pre- sent greater detail, the Hudson-Delaware Basins Area has been divided into 2/ the basins— shown on Figure HD-1. For all basins but the New Jersey Coast- al Basin an index map has been prepared to show an overlapping grid super- imposed on the basin outline. This map precedes the water quality classifi- cation maps. Hudson-Delaware Basin Area (Figure HD-1) This Area has been subdivided into eight major basins as defined below. 1) The St. Lawrence Basin includes the waters of the United States in the Lake Champlain, St. Regis and Lake Memphremagog Basins, all of which flow into Canada and into the St. Lawrence River. 2/ The term "basin" is not synonymous with the generally accepted defini- tion of a hydrologic basin, but means a group of, or a portion of, a hydro- logic basin whose limits are later defined in this text. - A - ------- 2) The Upper Hudson Basin includes the streams in the basin from the headwaters of the Hudson River to Waterford, N.Y. 3) The Mohawk Basin includes the streams in the Mohawk River Basin. Since it contains no interstate streams and therefore has no Federally ap- proved water quality standards, the water quality classifications and criteria for this basin have not been included in this Atlas. A) The Middle Hudson Basin is principally the Hudson River between Waterford and Peekskill, N.Y. 5) The New York-New Jersey Metropolitan Area includes the streams in the Hudson River Basin from Peekskill, N.Y. to New York Harbor. This basin also includes the interstate waters draining into New York Harbor from New Jersey, and those interstate waters west of the Queens-Nassau County bound- ary line and west of the Byram River. 6) The Long Island Basins Include those water bodies in Nassau and Suffolk Counties in New York which drain into Long Island Sound and the Atlantic Ocean. 7) The New Jersey Coastal Basins extend from Sandy Hook in the north to Cape May in the south, and include those streams and water bodies which drain into the Atlantic Ocean, either directly or through the numerous bays and channels. 8) The Delaware Basin includes the interstate waters in the basin from its headwaters to the Atlantic Ocean, and a few interstate waters in the State of Delaware that drain into the Chesapeake and Delaware Canal, directly into the Atlantic Ocean, or into Maryland. - 5 - ------- Index Maps The index maps show the overlapping grid of individual maps superimposed on the major basins of the Hudson-Delaware Basins Area. Each grid represents a page size map showing water quality classifications of interstate streams. In each grid is the number of the water quality classifications map for the area contained within the grid. In a few basins the grid has been modified to show clearly the interstate portions of a single river system such as the Poultney River or the Hackensack River. On the New York-New Jersey Metropolitan Area maps a separate system has been used to clarify the information shown. The first map (Figure LH-1) shows the interstate waters in red, while the intrastate waters and basin boundaries are shown in black. The second map of the same area (Figure LH-2) shows water bodies in black with the overlapping grids of individual maps in red. In addition to the grid index, the> index maps show most significant wa- ter bodies, both interstate and intrastate, within each basin. For purposes of orientation, all State boundaries and some major cities are shown on each basin map. Water Quality Classification Maps For all basins the classification maps are consistent in (a) water qual- ity classification method, (b) indication of change of classification, and (c) stream mileage. The water quality classifications of each water body are indicated on the maps by a capital letter in an oval or circle; e.g., . On the Long Island Basins maps the-circling of the water quality classifica- tion was omitted to conserve space. As a stream flows through different nat- ural and man influenced environments the use of the water and the water qual- - 6 - ------- ity change. At recognizable change points in water use or water quality the water quality classification changes. Where a change in water quality classi- fication occurs along a stream, an arrow indicates the change point; e.g., cates the separate zones of water quality. In estuaries the change points occur at recognized landmarks and are indicated graphically in this Atlas. On the New Jersey Coastal Map the classification change points are not clearly shown; information concerning the exact location of the head of tide—which is the boundary between fresh water classifications and tidal water classifications—generally is not precise. In tidal streams the head of tide is also the defined boundary between interstate and intrastate wa- ters. To help determine lengths of stream reaches and distances along tribu- taries a system of stream mileages—STORET-I—has been used. In STORET-I the mileage begins with 0.0 for each stream or tributary at its mouth and progresses upstream. On these maps the STORET-I mileage is indicated be- side the arrow showing the change point of classification. The use of STORET-I system has now been recommended by the Water Resources Council. The STORET-I mileages shown on these maps may differ slightly from previ- ously coded mileages of several agencies. The manner of subdivision of basin area varies from basin to basin. For example, the New York-New Jersey Metropolitan Area is depicted by sub- dividing the basin into individual.stream basins such as the Hackensack River Basin. The Delaware River Basin is divided Into zones or sections of equal classification defined as River Mile (R.M.) to River Mile with some in- dication of visual location of change point; e.g., Liston Point. Where a change occurs in a lake or bay, a solid red line indi- - 7 - ------- Although the scale of these classification maps varies from basin to basin, within each basin the classification maps which comprise the basin are consistent in scale. Unfortunately, this Atlas is able to show only inter- state streams and water bodies large enough to be visible on the maps. Interstate streams and water bodies are shown in red, and intrastate streams and water bodies are in black. The depicting of all interstate streams and water bodies would require an Atlas much larger than this edition. For more detailed data about an interstate water, or for information on streams not shown, the reader should consult the. appropriate water pollution control agen- cy. A list of such agencies in the Hudson-Delaware Basins Area is in Appen- dix II. When necessary, special notes are included on the maps to clarify the classifications. As an example, in Long Island Sound there are three zones of Class SB which are one mile square areas surrounding wastewater outfalls. WATER QUALITY CRITERIA TABLES Format of Tables In the Hudson-Delaware Basins Area 76 classes of interstate waters have been established by the six States and the Delaware River Basin Commission. The criteria defining the water quality required for the intended water var- ies from State to State. For example, New Jersey's Class FW-3 (best usage: bathing) groups "color, odor and taste producing substances" under a single criterion; while New York's Class B (which also provides for bathing as the best usage and is roughly comparable to New Jersey's FW-3) includes "colored wastes" with toxic wastes and other deleterious substances and makes no spe- cific mention of taste or odor. Even within a single State, parameter group- - 8 - ------- ing was not always uniform from class to class. This diversity in criteria, both within and among States, complicates comparisons from one class to an- other. For this reason, the most commonly used water quality parameters have been regrouped into a standard pattern for this report that would accurately summarize each of the 76 classes. The groupings chosen for this purpose were: 1. Floating Solids. 8. pH. 2. Settleable Solids. 9. Dissolved Oxygen. 3. Sludge Deposits. 10. Color. 4. Solid Refuse, Garbage, 11. Turbidity. Cinders, Ashes, Oils, Sludge or Other Refuse. 5. Sewage or Other Effluent. 12. Taste, Odor. 6. Oil, Grease, Oil 13. Toxic Wastes, Deleterious slicks, or Scum. Substances. 7. Coliform Density. 14. Heated Effluents and Temperature Criteria. For each class, the above parameters were fitted to this pattern and a series of tables was prepared showing the significant criterion applicable to each of these fourteen items. These tables of water quality criteria are i arranged in the following State order; Connecticut, Delaware, Massachusetts, New Jersey, New York and Vermont. The tables for the Delaware River Basin Commission (DRBC) follow those for Vermont. Comparison of State Standards On the basis of best usage and similar water quality criteria, the 38 classes of interstate waters in the States of Connecticut, Massachusetts, New Jersey, New York and Vermont have been arranged into 12 groups (see Table I, page 14). Groups 1 through 5 include all classes assigned to fresh or non-tidal surface waters, while Groups 6 through 12 include the classes - 9 - ------- assigned in saline or tidal waters. These groupings are not intended to im- ply that the two or three classes in a particular group are identical, but are used rather to indicate an approximate uniformity in water use and water quality criteria. Since the State of Delaware and the DBBC presented their classifications by specific reaches of water bodies, no attempt was made to include them in Table I. Comparison of Delaware River Basin Standards Within the Delaware River Basin, there are four States; Delaware, New Jersey, New York, and Pennsylvania; and the Delaware River Basin Commission, each of which has classified the waters under its jurisdiction within the basin. Thus, for most reaches of interstate water in the Delaware Basin there are both State and DRBC classifications. The State of New Jersey, rather than formulate separate classifications and standards for the main stem Delaware River and Bay, adopted the applicable DRBC classifications. A regulation of the DRBC indicates that,for any reach where applicable State standards require a higher quality water than those of the DRBC, the State's standards will be controlling. Terminology of Water Quality Criteria Each State prepared its own water quality standards in its own format and terminology. To the greatest extent feasible, the tables of water qual- ity criteria retain the individual State's terminology. The purpose of the following paragraphs is to point up some of the differences in the terminology of the State's standards. For example, some State's standards give concen- trations in ppm (parts per million), whereas other standards give the con- centration in mg/1 (milligrams per liter). For most waters, one ppm is approximately equal to one mg/1. - 10 - ------- The first six parameters in the table of water quality criteria are (1) floating solids, (2) settleable solids, (3) sludge deposits, (A) solid refuse, garbage, cinders, ashes, oils, sludge, or other refuse, (5) sewage or other effluent, and (6) oil, grease, oil slicks, or scum. For these parameters maximum allowable numerical concentrations have not been set. Generally the amount allowable for these parameters is descriptively defined. For example, "None in such concentrations that would impair the waters for assigned uses." Descriptions of allowable coliform bacteria values are extremely vari- able. The Delaware River Basin Commission uses effluent quality determina- tions while the various States use. instream quality determination for coli- form bacteria standards compliance. In water quality classes where there is no intended primary water contact—that is, water will not be ingested or come into contact with the human body to any large extent—the limita- tions on the amounts of allowable coliform are generally descriptive, such as, "None in such concentrations that would impair the waters for assigned uses." Where primary water contact is a probability, e.g., swimming and water supply, maximum allowable concentrations usually are stated. However, the method of stating the maximum limits is not consistent and runs the gamut of statistical procedures. Some methods of stating the limits of allowable coliform in these classes include median, arithmetic average, most probable number, average value, average most probable number, median most probable number, and geometric average. In addition, some States use a total coliform bacteria criterion rather than fecal coliform criterion. All the States and the DRBC require a minimum of secondary treatment of municipal wastewater or adequate disinfection of the effluent to keep the coliform levels within the standards. - 11 - ------- In saline water, shellfish harvesting is legal only where the coliform concentrations are below the recommended values stated in the respective class. Consequently, waters may be classified as appropriate for shellfish harvesting, but may be closed to harvesting due to existing high coliform concentrations. Thus, the appropriate State standards and the State shell- fish harvesting regulations should both be consulted to verify permissible shellfish harvesting areas. The limitations on pH in water have been described (a) descriptively, e.g., naturally occurring, (b) with numerical ranges, e.g., between 6.0 and 8.5, and (c) a combination of (a) and (b), e.g., between 6.5 and 8.5 unless naturally outside. For a few classes the pH was not specified. The minimum allowable concentrations for dissolved oxygen are expressed 3/ in ppm, in mg/1, in percent saturation,— or in a combination of percent saturation and mg/1. If the waters are considered appropriate cold water fish (trout) habitat, all States require a minimum dissolved oxygen level of 5 mg/1 or 5 ppm. The period for which these dissolved oxygen standards apply are not consistent from State to State. The standards may require that the minimum values apply (a) 16 hours per day, or (b) at any time, or (c) for a specific number of days (DRBC). Turbidity has not been specified in quantifiable terms by most of the States. The State of Delaware and the DRBC give both maximum value and max- imum monthly mean values and also relate the turbidity values to the natural background turbidity value. 3/ The amount of oxygen that can be dissolved in water decreases with in- creasing temperature. For fresh water, a saturated solution contains 14.6 mg/1 of dissolved oxygen at 0 C and 8.4 mg/1 at 25° C. - 12 - ------- Toxic waste criteria vary from "concentrations which will not impair water quality" to limiting concentrations for specific constituents such as copper, cadmium, cyanide, phenol, and detergents. Temperature criteria vary greatly. Some are given in terms of 1) maximum temperature of the water body, 2) maximum Increase in water temperature above naturally occurring water temperature, and 3) maximum allowable increase in water temperature per unit of time. Within the same State these values may vary according to the season of the year. Temperature criteria for fresh wa- ter classes may be less stringent than for salt water classes. If the concept of a mixing zone for introduction of thermal discharges into a water body is recognized in a set of standards, separate criteria for the mixing zone generally are specified as well as a definition of the limits of the mixing zone. Several portions of State's submissions have not been approved by the Secretary of the Interior. These are clearly indicated by notes and aster- isks (*) in the tables of water quality criteria. Several States are consider- ing the revision of parts of the water quality standards, especially the tem- perature criteria. The data given in this Atlas—all illustrations and tables of water quality criteria—have been abstracted from interstate water quality standards which are Federally approved as of July 1969. - 13 - ------- TABLE I SIMILAR FEDERALLY APPROVED WATER QUALITY CLASSIFICATIONS FRESH OR NON-TIDAL WATERS Group Best Use Conn.

The term "interstate waters," as defined in Section 13 (e) of the Act, means all rivers, lakes, and other waters that flow across or form a part of State boundaries, including coastal waters. 2. Within this definition, waters that flow across or form a part of State boundaries are subject to the provisions of Section 10 (c) (1) of the Act. 3. Waters that flow across or form a part of the international bound- ary between a State and foreign country are interstate waters within the meaning of the definition provided in Section 13 (e) of the Act and similarly subject to the provisions of Section 10 (c) (1) of the Act. 4. Coastal waters subject to the provisions of Section 10 (c) (1) of the Act are the ocean waters along straight coasts, the waters along indented coasts which are subject to the ebb and flow of the tides, and the waters of the Great Lakes. 5. As noted above, the definition of "interstate waters" is in terms of water bodies—"rivers," "lakes" and "other waters"—and is not limited to only those portions of these water bodies at the point at which they flow across or form a part of State boundaries. In effect, therefore, water quality standards are to be established for and made applicable to the entire stretch of the interstate waters within a State. 6. Tributaries of interstate waters, which are not in themselves inter- state waters, are not subject to the requirements of subsection 10 (c) (1) of the Act. However, it is important to note that the discharge of any matter into such tributaries which reaches interstate waters and reduces the quality of such interstate waters below the established water quality standards is subject to abatement under Section 10 (c) (5) of the Act. 1-17 ------- APPENDIX II DIRECTORY OF FEDERAL, STATE, AND LOCAL OFFICES HAVING INFORMATION ON WATER QUALITY CRITERIA Address Telephone State of Connecticut State Water Resources Commission 203-527-6341 Room 225, State Office Building 165 Capitol Avenue Hartford, Connecticut 06115 State of Delaware Water Pollution Control Section 302-678-4761 Division of Environmental Control Box 916 Dover, Delaware 19901 State of Massachusetts Division of Water Pollution Control 617-727-3855 Commonwealth of Massachusetts State Office Building 100 Cambridge Street Boston, Massachusetts 02202 State of New Jersey Division of Environmental Quality 609-292-4091 Water Pollution Control Bureau New Jersey Department of Environmental Protection Room 403, Health and Agriculture Building John Fitch Plaza P.O.

These and other interstate waters of the State will not be lowered in quality unless and until it has been affirmatively demonstrated to the Commission and the Department of the Interior that such change is justifiable as a result of necessary economic or social development and will not interfere with or become injurious to any assigned uses made of, or pre- sently possible in, such waters. This will require that any industrial, public or private project or an increased source of pollution to high quality waters will be required, if provided a permit, as part of the initial project design, to provide the highest and best degree of waste treatment available under existing technology, and, since for interstate waters these are also Federal standards, these waste treatment require- ments will be developed cooperatively." 2) Dissolved oxygen criteria for Classes C and SC now read: "Not less than 5 mg/1 for more than six hours during any 24-hour period, at no time less than 4 mg/1. For cold water fishery, not less than 5 mg/1 at any time." 3) Radioactivity standards have now been set and are the following maximum limits: Alpha Emitters: Not to exceed 3 picocuries per liter. Beta Emitters: Not to exceed 1,000 picocuries per liter. 4) Coliform bacteria limits have now been set for Classes C and SC, as follows: "Not to exceed an average in any 30-day period of 5000 nor exceed this value in more than 20% of the samples collected during the period." 5) Temperature criteria for Classes B, C, D, SA, SB, SCt and SD now read: "None except where the increase will not exceed the re- commended limit on the most sensitive receiving water use and in no case exceed 85°F or in any case raise the normal temperature of the receiving water more than 4°F." IV-1 ------- Addenda 12/70 Massachusetts Massachusetts The Secretary of the Interior approved the antidegradation statement of Massachusetts on November 25, 1970. This statement reads as follows: "Waters whose existing quality is better than the estab- lished standards as of the date on which such standards become effective will be maintained at such high quality unless it has been affirmatively demonstrated to the State that a change is justifiable as a result of neces- sary economic or social development and will not preclude uses presently possible in such waters. Any industrial, public, or private project or development which would constitute a new source of pollution or an increased source of pollution to high quality waters will be re- quired to provide the highest and.best practicable means of waste treatment to maintain high water quality. In implementing this policy, the Secretary of the Interior will be kept advised and will be provided with such in- formation as he will need to discharge his responsibili- ties under the Federal Water Pollution Control Act, as amended." IV-2 ------- Addenda 12/70 New York New York Standards Recommended Reclassifications The State of New York has approved and submitted for Federal approval the following upgradings of classifications: 1) Classification of Lake Champlain, that portion of the lake within New York State lying south,of Lake Champlain Toll Bridge at Crown Point and including South Bay, changed by State to Class B waters by the State in May 1969. 2) Classification of Hudson River, River Miles 84.A to 130.0, from boundary formed by east-west line through Light No. 28 on southern end of Esopus Island to boundary formed by east- west line through Light No. 72 off south end of Uoughtaling Island, changed by State to Class A in April 1969. IV-3 ------- Addenda 12/70 New York Review of New York State "Criteria Governing Thermal Discharges (Heated Liquids)" New York State adopted and the Secretary of the Interior approved water quality criteria which included standards for thermal discharges. They were published as a part of "Classifications and Standards of Quality and Purity for Waters", Part 701.3 et seq., Title 6, Official Compilation of Codes, Rules, and Regu- lations (6NYCRR). These regulations provide, for all classifications except Class SD, that the standard for thermal discharges (heated liquids) is "None alone or in combination with other substances or wastes in sufficient amounts or at such temperatures as to be injurious to fish life...or impair the waters for any other best usage 11 The statutory authority for these rules and regulations is the Public Health Law, Article 12 (formerly Article 6). Technical Bulletin 36, "Thermal Aspects of Discharges on Water Resources", was included as a part of the package submitted by New York and approved by the Secretary of the Interior in his second approval letter (August 7, 1967). The bulletin provides that, where discharges of thermal significance are con- templated, studies shall be conducted. It then provides criteria against which the studies should be evaluated. These criteria include maximum temperatures, degree rise and rate of rise limitations, and mixing zone provisions. The applicability of this bulletin as an enforceable water quality standard is unknown. It would appear that it is not legally binding as a standard. On July 25, 1969, the New York Water Resources Commission adopted "Criteria Governing Thermal Discharges (Heated Liquids)" and published them as Part 704 of 6 NYCRR pursuant to the Public Health Law, Article 12. These 'Criteria' provide that the standards for the waters of the State are 6 NYCRR 701.3 et seq. (as stated above) and that the standards shall be applied in accordance with the provisions that follow in the 'Criteria'.
