1. (1) Classification. For the purposes of applying 314 CMR 4.00, the surface waters of the Commonwealth are classified as shown in 314 CMR 4.06(2), (3), (4), (5) and (6)(b). The following terms used in the classification tables set forth in 314 CMR 4.06(6)(b): Figure A; Figures and Tables 1 through 27, have the following meanings:

   1. (a) Boundary. a description of the boundaries of the segment being classified.
   2. (b) Mile Points. for rivers and streams, the upstream and downstream mile points; it is also used to indicate the point at which a tributary enters the main stem of a river or stream.
   3. (c) Class. the appropriate water use Class for each segment in accordance with 314 CMR 4.05.

   4. (d) Qualifiers. indicates special considerations and uses applicable to the segment that may affect the application of criteria or antidegradation provisions of 314 CMR 4.00.

      1. 1. Public Water Supply denotes those surface waters that may be used as a source of public drinking water for a public water system as defined in 310 CMR 22.00: Drinking Water. They may be subject to more stringent regulation in accordance with 310 CMR 22.00, adopted pursuant to M.G.L. c. 111, and may have restricted use. These waters are designated for protection as Outstanding Resource Waters under 314 CMR 4.04(3). No discharge of dredged or fill material into wetlands or waters of the Commonwealth shall be allowed within 400 feet of the high water mark of a Class A surface water (exclusive of its tributaries), unless conducted by a public

      water system under 310 CMR 22.00, conducted by a public agency or authority for the maintenance or repair of existing public roads or railways, or conducted by a person granted a variance pursuant to 314 CMR 9.08: Variance. Any maintenance or repair of existing public roads or railways shall also include the removal or implementation of the highest and best practical method of treatment of stormwater discharges in accordance with 314 CMR 4.04(3) within the reasonable vicinity of the activity. Maintenance or repair of an existing public road or railway shall not include substantial reconstruction, substantial enlargement, replacement or realignment of any portion of the roadway or railway. The Department will presume that any reconstruction or enlargement is substantial and requires a variance under 314 CMR 9.08. The Department may determine that a public agency or authority has overcome the presumption based upon a showing that the activity proposed within 400 feet of the high water mark of a Class A surface water will result in the loss of less than 5000 square feet cumulatively of bordering and isolated vegetated wetlands and land under water, and that the entirety of the activity will improve water quality, or maintain water quality if removal or implementation of the highest and best practical method of treatment of stormwater discharges already has been achieved. 2. Outstanding Resource Waters denotes those waters that are designated for protection as Outstanding Resource Waters under 314 CMR 4.04(3). Outstanding Resource Waters are assigned at the discretion of the Department, as appropriate. An application to nominate a waterbody as an Outstanding Resource Water must be submitted in accordance with applicable Department application procedures and requirements. 3. Special Resource Waters denotes those waters designated for protection as Special Resource Waters under 314 CMR 4.04(4). Special Resource Waters are assigned at the discretion of the Department, as appropriate. 4. High Quality Waters denotes certain waters designated for protection under 314 CMR 4.04(2). Other waters as described in 314 CMR 4.04(2) also are high quality, although they are not necessarily denoted as high quality in the classification tables. 5. Shellfishing denotes those waters subject to more stringent regulation in accordance with the rules and regulations of the Massachusetts Division of Marine Fisheries pursuant to M.G.L. c. 130, § 75. These include applicable criteria of the National Shellfishing Sanitation Program. Approval for use of areas designated for shellfishing is issued by the Massachusetts Division of Marine Fisheries. To determine whether a particular water designated for shellfishing also is approved for use, the Massachusetts Division of Marine Fisheries and/or the appropriate local authority (usually the Shellfish Department) should be contacted. 6. Treated Water Supply denotes those Class B waters that are used as a source of public water supply after appropriate treatment. These waters may be subject to more stringent site-specific criteria established by the Department as appropriate to protect and maintain the use. See also, 310 CMR 22.00: Drinking Water. 7. Cold Water denotes those waters where dissolved oxygen and temperature criteria for cold water fisheries apply. Certain waters not designated as cold water in 314 CMR 4.00 may contain habitat that supports a cold water fish population and, in such cases, the cold water fish population and habitat shall be protected and maintained as existing uses. The Massachusetts Division of Fisheries and Wildlife is responsible for identifying cold water fish populations that meet their protocol, regardless of whether or not the water meets the cold water criteria in 314 CMR 4.00. Where a cold water fish population has been identified by the Division of Fisheries and Wildlife as meeting their protocol, but the water has not been documented to meet the cold water criteria in 314 CMR 4.00, the Department will protect the existing cold water fish population and its habitat as an existing use. 8. Warm Water denotes those waters where dissolved oxygen and temperature criteria for warm water fisheries apply. 9. Aquatic Life denotes those waters where Class C dissolved oxygen and temperature criteria apply. This designation is made only where natural background conditions prevent the attainment of a "higher use" designation.

      1. 10. CSO denotes those waters identified as impacted by the discharge of combined sewer overflows; however, a long term control plan has not been approved or fully implemented for the CSO discharges.

      2. 11. Partial Use, B(CSO) and SB(CSO) denotes those waters occasionally subject to short-term impairment of swimming or other recreational uses due to untreated CSO discharges in a typical year, and the aquatic life community may suffer adverse impact yet is still generally viable. In these waters, the uses for Class B and Class SB waters are maintained after the implementation of long term control measures described in the approved CSO long term control plan, except as identified in such plan. The Department may designate a segment partial use, B(CSO) or SB(CSO), provided that:

         1. a. a Department approved long term control plan provides justification for the overflows;
         2. b. the Department finds through a use attainability analysis, and EPA concurs, that achieving a greater level of CSO control is not feasible for one of the reasons specified at 314 CMR 4.03(4);
         3. c. existing uses and the level of water quality necessary to protect the existing uses shall be maintained and protected; and
         4. d. public notice is provided through procedures for permit issuance under M.G.L. c. 21, §§ 26 through 53 and regulations promulgated pursuant to M.G.L. c. 30A. In addition, the Department will publish a notice in the Environmental Monitor. Other combined sewer overflows may be eligible for a variance granted pursuant to 314 CMR 4.03(4). When a variance is not appropriate, partial use may be designated for the segment after public notice and opportunity for a public hearing in accordance with M.G.L. c. 30A.
      3. 12. Vernal Pools. No point source discharge shall be allowed to a vernal pool certified by the Massachusetts Division of Fisheries and Wildlife; and no discharge of dredged or fill material shall be allowed to a vernal pool certified by the Massachusetts of Division of Fisheries and Wildlife, unless a variance is granted under 314 CMR 9.08: Variance.
   5. (e) Treated Water Supply, Public Water Supply, and Shellfishing are assigned at the discretion of the Department, as appropriate.
   6. (f) Cold Water, Warm Water and Aquatic Life are considered consistent with the national goal uses and are assigned whenever attainable, as applicable.
2. (2) Wetlands. Wetlands bordering Class A Outstanding Resource Waters are designated Class A Outstanding Resource Waters. Vernal pools are designated Class B Outstanding Resource Waters. All wetlands bordering other Class B, SB or SA Outstanding Resource Waters are designated as Outstanding Resource Waters to the boundary of the defined area. All other wetlands are designated Class B, High Quality Waters for inland waters and Class SA, High Quality Waters for coastal and marine waters.
3. (3) Active and Inactive Reservoirs. All active and inactive reservoirs approved by the Department's Drinking Water Program after December 29, 2006 as a source of public water supply are designated Class A, Outstanding Resource Waters, regardless of whether they are listed in 314 CMR 4.06(6)(b): Figure A; Figures and Tables 1 through 27.
4. (4) Tributaries. Tributaries to a Class A public water supply include, but are not limited to, waterbodies from which water is manually diverted to the Class A public water supply.
5. (5) Other Waters. Unless otherwise designated in 314 CMR 4.06: Classification, Figures, and Tables, other waters are Class B, and presumed High Quality Waters for inland waters and Class SA, and presumed High Quality Waters for coastal and marine waters. Inland fisheries designations and coastal and marine shellfishing designations for unlisted waters shall be made on a case-by-case basis as necessary.

6. (6) Figures and Tables. All figures and tables referred to in 314 CMR 4.00 are set forth in a "List of Figures and Tables" in 314 CMR 4.06(6)(a). 314 CMR 4.06(6)(b) includes "Figure A, Commonwealth of Massachusetts River Basins and Coastal Drainage Areas" (showing river basins and coastal drainage areas) and Figures and Tables 1 through 27, inclusive (each figure providing a general orientation for the information in the corresponding table and each table showing those segments and classifications subject to qualifiers as set forth in 314 CMR 4.06(1)(d)).

APPENDIX B: Calculation of Fresh Water Ammonia Criteria Values

Criteria for ammonia as total ammonia nitrogen (mg/L TAN) are pH- and temperature-dependent. Criteria are derived in accordance with the equations set forth below, where MIN indicates the lesser of the two values separated by a comma, MAX indicates the greater of the two values separated by a comma, and T is temperature in degrees Celsius. The criterion maximum concentration (CMC or acute) equations differ according to the presence or absence of fish in the family Salmonidae.

1. 1. The CMC (acute) calculation:

   1. a. The following equation shall be used when Salmonidae species are present. Salmonidae species are presumed present in surface waters designated Cold Waters in 314 CMR 4.00; in MA Division of Fisheries and Wildlife's designated Cold Water Fisheries Resources (CFR); in surface waters where applicable data indicate the definition of a Cold Water Fishery is met ("Cold Water Fishery existing use"); and, as a rebuttable presumption, in any tributary to such designated Cold Waters, CFRs, or Cold Water Fishery existing uses:

      , or

   2. b. The following equation shall be used when Salmonidae species are absent. Salmonidae species are presumed absent in surface waters designated Warm Waters in 314 CMR 4.00; and in surface waters that are not designated Cold Waters, CFRs or Cold Water Fishery existing uses, or tributary to such designated Cold Waters, CFRs or Cold Water Fishery existing uses:
2. 2. The following Criterion Continuous Concentration (CCC or chronic) calculation shall be used in all surface waters:
