314 CMR 4.06
Classification, Figures, and Tables
(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:
(a) Boundary. a description of the boundaries of the segment being classified.
(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.
(c) Class. the appropriate water use Class for each segment in accordance with 314 CMR
4.05.
(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. 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 bya public agencyor 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 entiretyof 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. Public Water Supply – Abandoned denotes those surface water sources that were used
as public water supplies and that meet the definition of existing use at 314 CMR 4.02,
but have been abandoned as public water supplies pursuant to 310 CMR 22.25, are
physically disconnected from a public water system, and are no longer maintained as
active, inactive, or emergencysources as defined at 30 CMR 22.02. These surface waters
are no longer subject to regulation under 310 CMR 22.00: Drinking Water. However,
their designated use as a public water supply under 314 CMR 4.00 remains unchanged.
3. 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.
4. 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.
5.
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.
6. 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(usuallythe Shellfish Department)
should be contacted.
7. 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.
8. 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.
9. Warm Water denotes those waters where dissolved oxygen and temperature criteria
for warm water fisheries apply.
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.
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:
a.
a Department approved long term control plan provides justification for the
overflows;
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);
c. existing uses and the level of water quality necessary to protect the existing uses
shall be maintained and protected; and
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.
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.
(e) Treated Water Supply, Public Water Supply, Public Water Supply – Abandoned, and
Shellfishing are assigned at the discretion of the Department, as appropriate.
(f) Cold Water and Warm Water are considered consistent with the national goal uses and
are assigned whenever attainable, as applicable.
(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)
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) Tributaries. Tributaries to a Class A water qualified as a Public Water Supply or a Public
Water Supply – Abandoned per 314 CMR 4.06(1)(d) include, but are not limited to, waterbodies
from which water is manually diverted to the Class A Public Water Supply or Public Water
Supply – Abandoned.
(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) 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,

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.
The CMC (acute) calculation:
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
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. The following Criterion Continuous Concentration (CCC or chronic) calculation shall be used in all surface waters:

APPENDIX C: Calculation of Hardness-Dependent Fresh Water Dissolved Metals Criteria Values*
1.
Fresh Water criteria values for various ambient surface water hardness values shall be calculated using the following hardness-dependent equations:
a. For CMC using the equation: CMC (dissolved) = exp{mA [ln (hardness)]+ bA} (CF)
b. For CCC using the equation: CCC (dissolved) = exp{mC [ln (hardness)]+ bC} (CF)
2.
The hardness parameter used in the foregoing equations shall be obtained from the ambient surface water for the relevant location33, except that when the hardness is greater than 400 mg/L a default hardness of
400 mg/L may be used or, alternatively, the following procedures may be used:
a. for all metals listed in the following table, with the exception of copper, the actual hardness in the applicable hardness-dependent equation, where the resultant criterion is then adjusted by a WER calculated
in accordance with Appendix E; or
b. for copper only, the Biotic Ligand Model (BLM) as set forth in Appendix D, in place of the hardness-dependent equations.
3.
The other parameters used in the foregoing hardness-dependent equations shall be obtained from the applicable entries in the following table:
