SUMMARY
At the Second Session of the Conference on Pollution of the Navigable
Waters of Boston Harbor and Its Tributaries, the conferees agreed upon a
number of rec endations which were approved by the Secretary of the
Interior to alleviate the water pollution problems in Boston Harbor. A
number of these recc ndations were carried out; however, some of the
recoimiended implementation plans for waste treatment have not been carried
out according to the agreed upon schedules. The complete conference
reconinendations are contained on pages 1 through 7 of this report. The
major pollution problem which remains as an incomplete program is that of
the rehabilitation of tidegates in the city of Boston. Continuing salt
water intrusion into the MDC sewerage system from inoperative tidegates
decreases the efficiency of the waste treatment facilities.
The Coonwealth of Massachusetts Division of’ Water Pollution Control,
with the reconnendation of the Secretary of the Interior, engaged an engi-
neering firm to study the Boston Harbor pollution problem as it relates to
the Metropolitan District Commission (MDC) wastewater treatment facilities
at Deer Island and Nut Island. Results of this study indicate the sludge
disposal practices at these facilities are not suitable to meet water
quality standards. Alternate methods of sludge disposal by the MDC are
required to increase the overall efficiency of the treatment plants and
ensure compliance with water quality standards.
There has been considerable progress by the Federal Government, the
Commonwealth of Massachusetts, and coimnunities in the metropolitan area
toward alleviating the water quality problems of Boston Harbor; nevertheless,
a great deal more needs to be accomplished in programs and legislation
for pollution abatement.

CONCLUSIONS AND RECO! NDATIONS
CONCLUSIONS
1. The town of Hull is not complying with the Federal enforcement
conference implementation schedule for completion of a secondary sewage
treatment plant. However, it is following the State implementation
schedule which calls for completion of the facility by December 1973 which
is two years and nine months later than the Federal schedule.
2. Although progress has been made, the Metropolitan District
Commission has not complied with the Federal enforcement conference
schedule for rehabilitation of the Boston main drainage system tidegates
by May 1971.
3. There are a number of tidegates outside the Boston main drainage
system, within communities served by the Metropolitan District Commission
sewerage system, which are not included in the MDC rehabilitation program.
There is salt water intrusion into the metropolitan system from these
tidegates.
1 . The discharge of chlorinated raw sewage from the Moon Island
holding facility should be eliminated as soon as possible. The plans for
abandoning the Moon Island facility and Boston’s Calf Pasture Pumping
Station along with diversion of combined sewer overflows from Carson Beach
and L-Street in South Boston will contribute significantly to the improve-
ment of water quality in the Dorchester Bay portion of Boston Harbor.
Appropriation of funds for this project is contained in House Bill 167 now
before the Massachusetts Legislature. An alternative proposal contained
in House Bill 168 is the construction of a chlorination-detention facility
at Calf Pasture to provide treatment of combined sewer overflows when they
occur.
111
-------
5. The Commonwealth of Massachusetts, Division of Water Pollution
Control, has determined that the sludge disposal practices at the Deer
Island and Nut Island treatment plants violate Class SB water quality
criteria. Alternative sludge disposal methods must be developed.
6. The Nut Island wastewater treatment facility is operating under
overloaded conditions. Expansion of the plant or alternate measures are,
therefore, necessary.
7. The Massachusetts Legislature has passed a law providing for
the licensing of marinas to ensure adequate waste receiving and disposal
facilities for watercraft and their passengers at all marinas. To com-
plement this statute there are proposed regulations to control the dis-
charge of wastes from watercraft which are expected to be made law this
fall. These laws and regulations should be adequate for controlling water
pollution from watercraft.
8. The New England River Basins Commission, through the Boston
Harbor Water Quality Management Coordinating Group, is progressing towards
developnent of a long-term plan to provide for water quality in Boston
Harbor which will meet established water quality standards and will support
all legitimate water uses.
9. Time schedules were recommended by the conferees and were approved
by the Secretary of the Interior, for correcting pollution from Federal
facilities discharging to Boston Harbor.
RECOMMENDATIONS
It is recommended that:
1. The town of Hull continue its existing program toward completion
of a secondary wastewater treatment plant.
iv.
-------
2. The Metropolitan District Conm ission complete the rehabilitation
of all tidegates, regulators, stoplogs, and other control devices in the
Boston main drainage system by May 1972.
3. The cities of Boston, Cambridge, Chelsea, and Somerville be
ordered by the Massachusetts Division of Water Pollution Control to repair
as necessary, operate, and. maintain all combined sewer overflow structures
appurtenant to the metropolitan sewerage system, not later than December
1, 1971.
1 i. The Metropolitan District Commission complete the diversion of
Squantum sewage to Nut Island by December 1971. It is recommended that
plans for the abandonment of the Calf Pasture Pumping Station and the
Moon Island sewerage holding facility be implemented in 1972.
5. The Commonwealth of Massachusetts, Division of Water Pollution
Control, issue an order to the Metropolitan District Commission to provide
an implementation schedule for completion of a feasibility report by June
1972 relative to alternative methods of sludge disposal at the Deer Island
and Nut Island wastewater treatment facilities. This report should be
prepared by a competent research firm that has the capability to evaluate
new methods of sludge disposal. Upon completion of the feasibility report,
an implementation schedule be established for the construction of necessary
facilities.
6. The Metropolitan District Commission complete an engineering
report by September 1972 relative to future needs for the entire DC
sewerage system including the Nut Island and Deer Island treatment facilities.
Specific consideration should be given to the feasibility of expanding Nut
V
-------
Island or building wastewater treatment plants at other locations to
reduce flows to Nut Island.
7. That the Metropolitan District Commission strictly enforce its
existing regulations in order to abate the pollution resulting from the
substantial quantity of toxic materials being discharged to the MDC
sewerage system and then to Boston Harbor.
8. In order to reduce the frequency of discharges from the Boston
combined sewers into the Charles River Basin to once in five years, a
project must be devised by the Metropolitan District Commission and the
city of Boston which will go beyond the project presently contemplated to
reduce overflows from the Boston Marginal Conduit and its related systems
(the West Side interceptor and Stony Brook sewers) to a level consistent
with other Charles River combined sewer abatement projects. Both the
MDC and city of Boston should develop plans, within their own areas of
responsibility, toward the ultimate goal of reducing the combined sewer
overflows into the Charles River Basin.
9. The cities of Somerville and. Chelsea hire consultants to investi-
gate the adequacy 01’ their sewer systems and to make recommendations to
rehabilitate the systems and to abate pollution from combined sewer over-
flows. Upon completion of these studies, implementation schedules be
established by the Massachusetts Division of Water Pollution Control to
construct the necessary pollution abatement facilities.
10. The city of Cambridge meet the implementation schedule established
by the Commonwealth of Massachusetts (for separation of its combined sewer
system) not later than six months hereafter.
vi
-------
11. The city of Boston begin to implement the recommendations of
its consultants to rehabilitate and expand the existing sewer system, and
that a schedule for such work be developed by the city of Boston for the
consideration and approval of the Massachusetts Division of Water Pollution
Control.
12. The Massachusetts Division of Water Pollution Control establish
mixing zones for the discharges from the Nut Island and. Deer Island treat-
ment facilities, and that the description of mixing zones be submitted to
the Environmental Protection Agency for approval by November 30, 1971.
13. A program should be initiated for routinely removing small
amounts of floating debris, scum and oil which emanate from diffuse
sources throughout the harbor in order to achieve the goals of improved
water quality and enhancement of the attractiveness of the waters of Boston
Harbor.

INTRODUCTION
BACK OUND
On May 20, i968, the Secretary of the Interior held the First Session
of the Conference in the Matter of Pollution of the Navigable Waters of
Boston Harbor and Its Tributaries in Massachusetts, involving the
Co m nwealth of Massachusetts and. the Department of the Interior, under
the provisions of Section 10 of the Federal Water Pollution Control Act.
The conference was initiated by the Secretary in accordance with his
finding that substantial economic injury results from the inability to
market shellfish products in interstate commerce because of pollution and
the action of Federal, State, or local authorities.
Conclusions and recommendations approved by the Secretary of the
Interior of the first session of the conference are as follows:
1. The waters of Boston Harbor overlying some shellfish beds are
polluted.
2. The pollution results from the discharge of untreated or
inadequately treated wastes from municipalities, industries, combined
sewer overflows, tributary streams, debris and refuse, watercraft wastes,
and Federal installations, including Boston Naval Shipyard, Navy ships
berthed in Boston Harbor, the Coast Guard’s Base Boston, and Nike Ajax
Site B-36 (Hull). As a result, these waters are polluted by bacteria,
suspended solids, nutrients, and organic matter causing an oxygen demand.
3. As a result of the existing or potential pollution of these
waters, the Commonwealth of Massachusetts, under the cooperative agree-
ments governing the National Shellfish Sanitation Program, has completely
-------
closed some areas for the direct marketing of shellfish arid restricted
additional areas so that the shellfish must be processed through a
depuration plant.
. These closures have caused substantial economic injury resulting
from the inability to market shellfish or shellfish products in interstate
commerce .
5. The pollution of these navigable waters is subject to abatement
under the provisions of Section 10 of the Federal Water Pollution Control
Act, as amended.*
6. In some areas, the pollution of these waters has resulted in an
unsightly appearance, the excessive growth of aquatic plants, objectionable
odors, sludge deposits, and limited use of the waters for recreational
bathing, boating, and aesthetic enjoyment.
7. The State agency has taken appropriate action to date under State
law to abate pollution. The delays in abating the pollution are due to
the very complicated nature of the problem.
8. The conferees agreed that a technical committee be appointed to
be chaired by the Chairman of the Massachusetts Department of Natural
Resources, the Federal Chairman of the New England River Basins Commission,
and the Northeast Regional Director of the Federal Water Pollution Control
Administration. The committee shall be empowered to appoint subcommittees
and expand its membership. The committee will make an evaluation of the
following and report to the conferees at six-month intervals. The scope
of such evaluation will include but not be limited to:
*Conmds joner Yasi took procedural excpetion to this conclusion by
the Federal conferee.

-------
a. A status report of pollution abatement required by the
Division of Water Pollution Control for all municipal and industrial
contributors listed in the Massachusetts standards of water quality
including Federal installations as well.
b. A report of the attainment of Boston Harbor water
classifications by the several municipal and industrial pollution
sources.
c. Delineation of an overall plan to control the dumping of
garbage or refuse along the shores and in the harbor.
d. A program to ii rove dump sites and correct the problem
of sunken vessels, deteriorating piers, and debris.
e. Investigation of suitable Federal and State laws to
control oil pollution and wastes from watereraft.
f. Study of a deep tunnel proposal from a water quality and
use standpoint as well as consideration of the most feasible means
of financing such a project.
g. Plans to assist Federal authorities in the implementation
of treatment works for Federal installations.
9. Federal installations will be required to meet the time schedule
of Massachusetts’ water quality standards. Nike Ajax Site B-36 (Hull)
will be required to make a determination in six months as to whether it
will join the mun.icipal system or provide its own installation and have
its remedial system or facility put in by 18 months from the date of this
conference. The Coast Guard’s Deer Island Light Station will be given
six months to put in a temporary facility. The Coast Guard’s Base Boston
Station should complete its remedial facilities by May 1970. Base Boston
3
-------
vessels in port are to observe May 1970 as the completion date for their
remedial facilities and for a sewer line to collect their sanitary wastes.
The Naval shipyard should have its remedial facility for collection and
control of its wastes from machine shop and tank cleaning operations
completed by July 1969.
10. The conference may be reconvened upon the call of the
Chairman.
Conclusions and recormnendations approved by the Secretary of the
Interior following the second session of’ the conference held on April
30, 1969, are as follows:
1. That the implementation plans set forth as follows by the
Commonwealth of Massachusetts for the various municipalities and industries
be approved:

2. That a consulting engineering firm be engaged by the Commonwealth
of Massachusetts to:
a. Evaluate the tidal and current patterns and the
dispersion characteristics of Boston Harbor, particularly as
it effects the Deer Island and Nut Island treatment plants.
The evaluation will include the utilization of mathematical
modeling techniques directed to the determination of mixing
zones, and recommendations for sludge disposal, and chlorina-
tion practices. This report shall be completed by the winter
of 1970-1971 and an implementation schedule incorporating the
approved recommendations shall be developed directly thereafter.
b. Provide an evaluation and recommendation as to the
most practical and economical solution to the overall Boston
Harbor problem considering the effects of tributary streams
and combined sewer overflows.
c. As a further step toward advancing the Boston Harbor
water quality control program, the Commonwealth c i’ Massachusetts
adopt a marina control law and a boat pollution control law
for the protection oI’ inland and coastal marine waters.
d. That a comprehensive water quality management plan
be completed for the Boston Harbor drainage area by the New
England River Basins Commission in cooperation with the State
and Federal agencies concerned.
e. That all pollution abatement measures should be
taken to control the pollution from Federal installations
within the schedule outlined below:

collect these wastes by May 1970.
Implement plan to eliminate the discharges
of all industrial wastes to Boston Harbor
by November 1969.
Complete program to permanently connect
to Boston sewer system by May 1970.
Construct facilities to eliminate sewage
discharges by June 1970.
Continue testing program to find an
acceptable method of treating wastes
from vessels.
The Massachusetts conferees made the following recommendations,
with the Federal conferee abstaining:
In noting the detrimental effect of Federal construction grant
cutbacks in appropriations on State water pollution control programs,
the conferees of the Commonwealth of Massachusetts urge that the Federal
Water Pollution Control Administration and the Secretary of the Interior
recommend to the Congress of the United States the adoption of a fiscal
program consistent with the implementation programs adopted by the States
throughout the nation.
It is further recommended that legislative amendments to the Federal
Water Pollution Control Act do not vary the present grant percentages to
communities for construction of waste treatment facilities or if
alternative means of financing are introduced, the alternative financing
measures are the equivalent of the present percentages specified in the Act.
6
-------
These conferees would also urge the passage of a separate
appropriation to finance the reimbursable clause of the Federal act to
repay States that have or win prefinance the eligible Federal portions
of treatment facilities in anticipation of future Federal reimbursements.
Table 1 is a sunm ary table giving the status of the recommended
implementation plans as set forth by the Commonwealth of Massachusetts.
Detailed explanations of the status of each of the recommendations, in
particular those incomplete programs, are given in the following sections

CURRENT STATUS OF ENFORCF NT CONFERENCE RECO1 ENDATIONS
Town of Hull
At the second session of the conference, the conferees agreed that
the town of Hull should construct a secondary wastewater treatment facility
with disinfection. The implementation schedule for Hull’s treatment plant
is:
Federal Enforcement
Conference Dates State Dates Status
Preliminary plans submission - - October 1969 Compliance
Final plans submission - - June 1972
Funding completed - - February 1970 Compliance
Start of construction - - September 1972
Facility in operation March 1971 December 1973
The Federal schedule was submitted by the Commonwealth of Massachusetts
at the second session enforcement conference and approved by the Secretary
of the Interior. The town of Hull did not comply with this implementation
plan; and therefore, the Massachusetts Division of Water Pollution Control
issued the new schedule to the town under formal Division orders. Hull
is currently in the process of selecting a consultant engineering firm to
prepare final engineering plans, and the town believes it will be able to
meet the June 1972 date for submission of these plans.
Tidegates in the Boston Main Drainage System
In the metropolitan Boston area there are in excess of 100 storm-
water drainage outlets to tidewaters while in the Boston main drainage
system there are approximately 72 outlet structures with about 200
individual tidegates appurtenant to these outlets. The second session
of the conference pointed out that a large number of tidegates appurtenant
to the stormwater drainage outlets within the Boston main drainage system
10
-------
were inoperative allowing the intrusion of’ salt water into the sewerage
sy-stem. This salt water intrusion increases the flow to the Deer Island
wastevater treatment plant and reduces the overall efficiency of this
primary waste treatment facility.
As of July 19, 1971, there were 22 combined sewer outlets in the
Boston main drainage system which were operational, 6 under construction,
2 proposed for construction, and li 2 under investigation. This information
was supplied by the Metropolitan District Ccsmdssion.
The Massachusetts Attorney General, in a letter of August 21, 1969,
to the Chairman, Water Resources Commission, stated that it was his
opinion that the responsibility for rehabilitation of the Boston main
drainage system tidegates rests with the Metropolitan District Commission.
The MDC is proceeding slowly with the repairs, having repaired about 7
outlets completely since February 1971, and has not met the May 1971 date
of completion as recommended by the enforcement conference.
Tidegates outside the Boston Main Drainage System
In the Charlestown and East Boston sections, which are not a part
of the Bosthn main drainage system, there are 22 combined sewer outlets
to tidewaters. Also outside the system, but within the metropolitan
region, are Cambridge, Chelsea, and Somerville. The tidegates, regulators,
stoplogs and other flow control devices in these communities must be main-
tained in. operating condition. Programs for inspection and rehabilitation
of these systems should be accomplished by these communities as soon as
possible.
11
-------
Boston’s Calf Pasture Pun ing Station and Moon Island Facility
The Moon Island sewerage holding facility now receives sewage from
only the Squantum section of Quincy. About one to two million gallons per
day of sewage is currently discharged on outgoing tides after chlorination.
There is a project underway by the MDC to divert the Squantum flows to
the Nut Island facility which is scheduled for completion by December
1971.
The Calf Pasture Pumping Station and the Moon Island holding facility
will be completely abandoned in conjunction with a proposed city of Boston-
MDC project to divert combined sewage overflows from Carson Beach and L-
Street in South Boston for screening, settling, chlorination, and discharge
to Reserved Channel. The appropriation for this project is contained in
House Bill 167 which was reported to the Massachusetts Senate Ways and
Means Committee on August 31, 1971. The estimated cost for the project
is in excess of $33,000,000.
An alternative proposal contained in House Bill 168 is the construction
of a chlorination-detention facility at Calf Pasture to provide treatment
of combined sewer overflows when they occur. This bill was also reported
to the Senate Ways and Means Committee on August 31, 1971.
Cambridge Combined Sewers
The city of Cambridge has an extensive combined sewerage system.
Frequent overflows occur to the Charles River. Overflows also affect
Alewife Brook (Mystic Basin) and Boston Inner Harbor. In 1968, a con-
sultant firm recommended that Cambridge immediately initiate a five-year
program of construction to reduce combined flows to the MDC system to
within the design capacities of that system with a corresponding reduction
12
-------
in sanitary waste overflow to the Charles River and Alewife Brook. A
second phase was also recommended - a long-term program of construction
for total separation of all existing combined sewer areas.
The Commonwealth of Massachusetts placed Cambridge on an implementation
schedule to carry out the recommendations. The schedule is as follows:
Phase To be completed
I September 1972
II September 1973
III September 19714
I V September 1975
V September 1976
Boston Combined Sewers
In 1967 a consultant for the city of Boston recommended that Boston
rehabilitate and expand their existing sewer system, which included repairs
to tidegates and. regulators. Many of Boston’s sewers are overloaded and
in need of repair. The city has not implemented these recommendations.
Somerville and Chelsea Combined Sewers
The cities of Somerville and Chelsea have combined systems. Overflows
from these systems affect the quality of Alewife Brook, Mystic, and Chelsea
Rivers and the Boston Inner Harbor. It is necessary to engage a consulting firm
to investigate the adequacy of their sewer systems and make recommendations
to rehabilitate the system.
Boston Marginal Interceptor and Pumping Station
The MDC plans, in conjunction with the proposed Charles River Dam,
to extend the Boston Marginal Conduit to a point below the proposed dam,
to intercept overflows that now exist between the location of the present
dam and the proposed dam from Cambridge, Somerville and Boston, and to
construct a pumping station so that the flows in the Marginal Conduit can
13
-------
be discharged to the tide water at all tides arid provide partial treatment
to the overflow.
The Boston Marginal Conduit interceots corr bined sewage from the West
Side Interceptor and Stony Brook system which are city of Boston sewers.
At the present time, when a rainfall occurs during high tides, all combined
sewage is discharged to the Charles River Basin. The proposed project will
reduce overflows to the Charles River, but there ma r be frequent discharges
of combined sewage to the Charles River Basin and the Back Bay Fens area
from both the MDC Boston Marginal Conduit and the city of Boston sewers.
Massachusetts’ actions regarding the Boston Harbor pollution problems
In accordance with the recoim endations of the second session of the
Boston Harbor conference, as presented in the Introduction of this report,
the Massachusetts Division of Water Pollution Control engaged the services
of Hydroscience, Inc. of Westwood, New Jersey, to evaluate the Boston
Harbor pollution problem, in particular, as it relates to the Deer Island
and Nut Island waste treatment plants and the effects of tributary streams
and combined sewer overflows.
The Hydroscience report has been completed. After consideration of
this report, the Director, via letter of June 1 , 1971, informed the
Commissioner of the MDC that the report evidences inadequate sludge dis-
posal practices at the Deer Island and Nut Island waste treatment facilities.
Based upon violation of water quality standards for Class SB waters, he
recommends the MDC undertake to have an engineering study prepared relative
to alternative sludge disposal methods at both the Deer Island and Nut
Island plants.
EPA personnel collected data on the sludge and sewage effluent from
-------
the Deer Island and Nut Island facilities. This data and discussion of
it is presented in the next section of the report. Based on this data
and the Hydroscience data, the EPA wrote to the Coninissioner, MDC, on
July 19, 1971, to support the position of the Division of Water Pollution
Control.
An additional problem at the Nut Island wastewater treatment plant
is that the plant is currently operating under overloaded conditions.
The Fifty-first Annual Report of the Metropolitan District Commission,
Sewerage Division, for the fiscal year ending June 30, 1970, reports that
the Nut Island plant received an average flow of 12.79 million gallons
per day above the average design flow of 112.0 mgd. Operation under
overloaded conditions decreases the efficiency of the treatment plant,
pointing out the need for increasing the capacity of the plant to allow
the treatment intended, by the design. The water quality of the receiving
waters should be examined periodically to determine whether or not the
degree of treatment should be increased..
Sampling at Deer Island and Nut Island Treatment Facilities
On March i6 and 31, 1971, EPA personnel collected samples of the
Deer Island and Nut Island sludge and sewage effluents. The results of
the analyses of these samples are presented in Tables 3, 1!., and 5.
It is indicated that the discharge of digested sludge and treated
sewage from the waste treatment plants violates the following water quality
criteria for Class SB waters:
Item Water Quality Criteria
1. Sludge deposits-oils- None allowable
grease-solid refuse
15
-------
Item Water quality Criteria
2. Coliform bacteria per Not to exceed a median value of 700
100 ml and not more than 2300 in more than
10 percent of the samples during any
monthly sampling period.
3. Chemical constituents None in concentrations or combinations
(metals) which would be harml’ul to human, animal
or aquatic life or which would make the
waters unsafe or unsuitable for fish or
shellfish or their propagation, impair
the palatability of same, or impair the
water for any other usage.
Class SB waters should be suitable for bathing and recreation purposes,
including water contact sports, industrial cooling, excellent fish habitat;
good aesthetic value; and suitable for certain sheilfisheries with depura-
tion. It is evident that the existing sludge discharges directly interfere
with these assigned uses. Figure 1 shows the Limits of the SB classifica-
tion for Boston Harbor.
The results of the metals scan analysis on the sludge sample from
the Nut Island sludge digester reveals concentrations of copper, cadmium,
lead, zinc, nickel, and chrcmiium. Sludge samples analyzed for mercury
revealed concentrations of that metal also. Concentrations of the metals
as found could be detrimental to the well being of aquatic organisms,
particularly fish food organisms, and other aquatic life. There is also
indicated another potential problem from the discharge of sludge with
these concentrations of metals. The sludge is discharged into the
President Roads area of Boston Harbor during the first three hours of
ebb tide. Hydroscience, Inc. reports in the “Final Report, Development
of Water Quality Model of Boston Harbor,’ July 1971, that the present
practice of discharging sludge for the first three hours of ebbing tide
16
-------
results in the deposition of approximately 15 to 20 percent of the sewage
sludge solids in the portion of the harbor west of Deer Islarui. Concentra-
tions of mercury, lead and zine, as found, exceed those acceptable in the
EPA criteria for dredge spoil disposal.
Flow data provided by the Nut Island treatment plant operator on
March 31, 1971, indicates the plant was operating under overloaded conditions.
At the Deer Island facility the sludge is discharged through the
sewage effluent line where there is about a 300 to 1 dilution of the
sludge with the chlorinated sewage effluent. Although there is a sub-
stantial reduction of coliform organisms in the discharged sludge, dis-
infection during this period is, nevertheless, inadequate.
Marina Control and Watercraft Pollution Control Laws
The Massachusetts Legislature approved on August 18, 1970, Chapter
693 of the Acts of 1970, Section 2, amending Chapter 91 of the General
Laws, which pertains to the licensing of marinas. In general, the law
stipulates that licenses to operate marinas shall not be granted unless
adequate sanitary waste collection, treatment, and disposal facilities
are provided; adequate dockside toilet facilities are provided for the
occupants of watereraft; and adequate trash receptacles are provided for
litter and refuse. This law will go into effect on May 15, 1972.
The Division of Water Pollution Control has held public meetings
for approval of the proposed rules and regulations for the control arid.
prevention of sewage and other waste material from watercraft. The next
step is to file the proposed rules and regulations with the Secretary of
State for presentation to the State Legislature. If approved, the law
will go into effect on May 15, 1972.
A copy of the existing law is given in Appendix A.

Ni BC Cc iprehensive Water Quality Management Plan
In May 1970 the New England River Basins Coutnission published a
report, prepared by the Boston Harbor Water Quality Management Coordinating
Group, ot a Plan of Study for a Water Quality Management Program for
Boaton Harbor. The goal of the plan is to ‘ ystematically develop a
total water quality Iwisgement program for the harbor aM tributary area
to insure the waters will meet established water quality standards and
will be capable of supporting all legitimate water uses.”
Progress toward developing the Cou rehensive Water Quality Management
Plan was reported in October 1970 by the coordinating group. The elements
of progress acccinplished at that time were the formulation of the group
working cooperatively to develop a guideline for short- and long-term
action to achieve the water quality goals and development of a plan of
study to ensure coordinated development of plan formulation. A
mathematical water quality del to assist in decision making has been
completed. Preparation of planning inputs is well underway. A simplified
diagram for plan development is shown in Figure 2.
There will be interim reports and recoimnendations published each
year and the final plan should be completed by June 1972.
Metropolitan District Coixn ission Regulations
The sa 1e data presented on the metal scan analysis on the sludge
samples from the Nut Island sludge digester indicate a substantial
quanity of toxic metals are discharged into the MDC sewerage system.
The MDC has taken steps to prevent this by issuing rules and regulations
covering the discharge of sewage, drainage, substances or wastes into
any sewer under its control, or any sewer tributary thereto. Strict

building sewer carrying industrial rastes shall install a ‘ uitable control
or measuring device together with such neceisary manholes, chambers, meters
any other appurtenances in the building sewer to facilitate obse at1on,
sampling, and measurement of the wastes, such manhole or chamber, when re
quired, shall be accessibly and safely located and shall e constructed in
accordance with plans approved by the Commission. The manhole, chamber,
meters, etc., shall be installed by the owner at his expense, and shall be
maintained by him so as to be safe and accessible and in good operating
condition at all times. The records from the meters and measuring devices
shalLibe furnished to the Commission upon request therefor.
9. All measurements, tests, and analyses of the characteristics of waters and
wastes to ‘ hich reference is made in these rules and regulations shall be
deten rined in accordance with the latest edition of “Standard Methods for the
T xamination of Tater and Nastewater,” published by the American Public Health
Associ tion, and shall be determined at the control manhole o
or by use of suitable samples taken at the control manhole or chamber. In the
event that no special manhole or chamber has been provided, the control point
shall be considered to he the nearest do rnstream manhole in the public sewer
to the point at which the b’ ilding sewer s connected. S mpling ahall be
carried out by custom rily accepted methods to reflect the effect of constit-
uents upon the sewerage ‘orks and to determine the existence of hazards to
health and property. The particular analyses involved will determine ‘ rhether a
twenty-four (24) hour composite of all effluents of the pre-iises is appropriate
or whether a grab sample or samples should be taken. BOD and suspended solids
an 1’se3 shall normally be obtained from 2 4 hr. eorrnosites of all effluents
whereas pH’s shall normally be determined from periodic grab sanrnles.

10. Failure on the part of any municipality to comply with any rule or regula-
tion contained herein, or with any order maae under the authority thereof,
lawfully affecting such municipality, shall be sufficient cause for the
levying and collecting by the Commission from such municipality of such
additional assessment or assessments as the Commission may deem necessary
to compensate it for the disposal of sewage, drainage, substances or wastes
from such municipality; provided, that no such additional assessment shall
be lev ied on any such municipality in any one year which shall exceed the
lesser of an amount equal to one twentieth of one per cent of the taxable
value of such municipality, or the sims of two hundred thousand dollars.
Ch.705, Acts l9 5
11. No statement contained in this article shall be construed as preventing
any special agreement or arrangement between the Corrmission and any munici-
pality whereby an industrial wa3t.e of unusual strength or character may be -
accepted by the Comission.
