In accordance with the provisions of Article 1, Regulation 2 of the State Sanitary Code and under the authority of Chapter 111, Section 131 of the General Laws and any other powers thereto enabling, the Board of Health of Marshfield hereby adopts the following regulations relative to the disposal of Sanitary Sewage in Unsewered Areas as Supplements to Title 5 of the State Environmental Code to be effective as of September 1, 1978.
All section numbers are derived from the sections of Title 5 to which they apply.
Section 1 DEFINITIONS
1.1 The following abbreviations are used herein:
SEC - Refers to the STATE ENVIRONMENTAL CODE.
1.2 The following definitions are in place of those shown in SEC Title 5, Regulation 1:
ABOVE GROUND SEPTIC SYSTEM
A system where any part of the leaching facility (including pits, fields, chambers, pipes stone or peastone) is installed above the natural grade of the land on the lot. Access manholes by themselves do not cause a septic system to be considered an above ground septic system.
APPLICANT
Applicant means the person named on the Disposal Works Construction Permit
Application as the owner of the property which is the site of the proposed septic system.
BOARD
Board of Health in the Town of Marshfield, Massachusetts or its agent
DEWATERED PERCOLATION TEST
A percolation test done in accordance with the procedures outlined in Title 5, Section 15.03 (5) except that some or all of the four (4) feet of naturally occurring pervious soil is saturated by ground water and some temporary dewatering of the soil is necessary so the water can drain away from the soil and a standard percolation test can be performed.
GROUND WATER MONITORING WELL
Piping placed in the ground for the purpose of obtaining ground water elevations or samples for testing.
IMPERVIOUS MATERIAL
Soils having a percolation rate greater than 20 minutes per inch and including but not limited to ledge, hardpan, peat, loam and organic matter (see SEC Title 5, Reg. 3.4e (5))
MAXIMUM GROUND WATER ELEVATION
Maximum ground water elevation means the height of the ground water table when it is at its maximum level or elevation. (See Regulation SEC Title 5, Reg. 3.3 of these local rules)
POTABLE WATER SUPPLY
A water supply of sufficient quantity and pressure to meet the needs of the occupants of the dwelling, lot or building, connected with a public water system or with any other source that the Board of Health or agent has determined, by requiring the water to be tested, does not endanger the health of any potential user and is fit for human consumption.
A source shall be deemed potable, which meets, at a minimum, all the current primary drinking water standards. Other tests may be required, by the Board or agent, if it is deemed necessary.
PRIVATE DRINKING WATER WELL
Any privately owned well supplying water for human consumption to any individual dwelling or building. Any well, pit, pipe, excavation, shaft, spring casing, hole or other source of water to be used as a potable private drinking water supply

- sources of water supply within 300 feet of the sewage system. In all cases where there are existing dwellings or structures on abutting properties, applicants for a Disposal Works Construction Permit shall make inquiry of those abutters to the property or properties to ascertain the presence or absence of a private well on such properties. The applicant shall supply this documentation to the Board and the Department of Public Works when applying for a Disposal Works Construction Permit.
- pertinent elevations, including elevation of road, cellar floor, top of foundations, garage floor, and elevation schedule for sewage disposal system, including invert elevations at house foundation, entrance to septic tank, entrance to distribution box, beginning of each leaching line, end of each leaching line, and bottom of leaching pit, trench or bed. Accompanying this schedule, the proposed final ground elevation at each of the called-for-points along the disposal system shall be shown.
- sufficient additional elevations must be shown, including final grades at each or the four corners of the building, to indicate clearly how the surface drainage on the property is to be handled. Plan must be designed to drain the property satisfactorily to prevent
adverse drainage to adjoining property.
- all present elevations must be shown at true spot elevations. All proposed changes in elevation must be shown in the form of two foot contour lines, clearly showing the
proposed change in topography,
- a benchmark must be established and maintained until after the final inspection by the design engineer. Its location must be shown in the plan.
- watercourses, streams, brooks, ponds, lakes and the 12-foot tide line within 200 feet. Requirement by Engineering Department - the benchmark shall be on mean sea level or an elevation obtained from the Engineering Department.

2. Application shall be made before percolation tests, ground water determination, and other on site inspections are witnessed or performed by the Board of Health. All data from observation pits, percolation tests, ground water determinations, shall be entered directly on the application form at the time such tests and observations are witnessed by the Board of Health. The representative of the Board of Health shall date and sign the results of the tests, which he witnesses.
d. Any permit granted will not be valid if conditions set forth in the application have changed prior to or during actual construction of the sewage disposal system.
No permit will be issued until an adequate supply of water is assured. If a municipal well
is the source, all applicants for a Disposal Works Construction Permit may be required to submit a written statement to the Board of Health, from the Department of Public Works, as to the availability of an adequate supply of water in sufficient quantity to provide adequate pressure to the occupants of the proposed building or dwelling. The applicant may also be required to provide a statement from the Fire Department that adequate fire flow will be provided to the dwelling or building. If a private well is the source, the well must be dug and the water tested before a permit will be issued.
f. Sewage system must be installed under the direct supervision of the designing engineer. At the time of final inspection he must submit a letter stating that this system has been installed according to his plan and provide measurements of "tie-ins" or an "as-built" plan of the system.
The ‘As built’ must include final contours for any plans in which the original contours over and around the septic system leaching area and/or any components of the system have been changed, or were designed to be changed.
The ‘As built’ must include distances from the septic system and/or any component of the system to the property line, in all cases where the distance from the septic system or component is less than twenty-five (25) feet from the property line.
‘As builts’ must be submitted to the Board of Health office no later than thirty days after the Design Engineer completes the final inspection of the septic system.
Special conditions for variances – All Title 5 variances, local upgrades, or local variances that are granted by the Board of Health with conditions that limit or prohibit increases in design flow, or otherwise limit or prohibit alterations or repairs to the structure shall be subject to the following requirement prior to issuance of a Certificate of Compliance: The variance or upgrade form, with special conditions specified, must be recorded at the Registry of Deeds. Proof of recording must be presented to the Board of Health.
g. SEPTIC SYSTEMS REQUIRING EXCAVATIONS
PURPOSE:
To protect the public health and interest in the preservation of natural resources, to conserve the value of the land, to protect the public concerns in safe and healthy land areas, to insure that permanent changes in the surface contours of land resulting from the removal and or realignment of earth materials will leave the land in a safe and proper condition for appropriate reuse without requiring excessive and unreasonable maintenance or danger of damage to public and private property and also provide that earth removal activities shall be conducted in a safe manner with due regard to safety and with minimal detrimental effect upon the neighborhood in which the activities are located,
On any lot where a subsurface septic disposal system is to be constructed that will involve the removal of impervious material(s) as defined in 310 CMR 15.01 and/or the bringing in of fill as defined in 310 CMR 15.02 (17) from off-site in amounts greater than 1200 cubic yards or if any part of the system is above existing grade the following shall be required in addition to 310 CMR 15.00:
A permit from the Board of Health based on the following:
a. Future reserve area shown on plan to be prepared in conjunction with the primary
system;
b. Work can not be done in any calendar year from November 15 to March 15th without
explicit Board approval:
The repair, reconstruction or alteration of an existing subsurface septic disposal system which will involve the removal of impervious material(s) as defined in 31O CMR 15.01 and/or the bringing in of fill as defined in 31O CMR 15.02(17) in amounts greater than 1200 cubic yards or if any part of the system is above existing grade - the following shall be required:
The applicant's engineer after a field survey of site conditions and prior to the development of plans may review site conditions with the Board to discuss the application of all items listed and required for new construction. From this discussion the Board shall indicate which provisions must be adhered to and which are to be waived with the Board stating reasons for conditions and any waivers.
2.4 h DISPOSAL SYSTEMS WITH DESIGN FLOW IN EXCESS OF 5000 GALLONS PER DAY
Purpose: To protect the ground water used for drinking water purposes from contamination which may result from concentrated sewage disposal.
Applicability: all proposed subsurface disposal systems with design sewage flows of 5000 gallons per day or greater per lot.
Procedure: The applicant(s) must demonstrate, by written report, to the satisfaction of the Board of Health that current drinking water standards will be met at the downgradient property limit and that current surface water quality standards will not be violated at downgradient lakes, ponds and streams due to the effluent from the system.
The written report shall be based upon the following scope of work:
a. Geologic borings
b. Water Table Map (one foot interval contours) showing ground water flow direction,
c. Projections of downgradient concentrations of nitrate-nitrogen (or other chemicals
as requested by the Board of Health).
Projections of downgradient water quality will be determined utilizing two-dimensional solute transport models and input variables approved by the Board of Health.
Currently approved models include:
1. USGS Konikow and Bredegoeft (1978)
2. Random Walk, Prickett and Lonquist (1981)
Other models may be approved by the Board upon request
Currently approved input variables include:
1. Transmissivity to be determined by on-site pump test (minimum of 4 hours)
2. Aquifer thickness to be determined by on-site boring locations of confining layers and estimated plume thickness.
3. Dispersivity - determined by site specific testing
4. Hydraulic gradient as determined by site specific water table map
5. No retardation factor
6. Sewage flows as determined by Title 5 design flows
Applicants who receive permits under this section shall install a minimum of three downgradient and one upgradient ground water monitoring wells. Ground water flow direction will be determined from the USGS (1987) water table map and from site specific observation wells where necessary. Wells will be constructed of two-inch threader flush joint PVC pipes with locking caps. Ground water samples will be obtained on an annual basis utilizing a bailer following standard well evaluation procedures (three well volumes will be removed prior to sampling).
Evacuation is most easily accomplished using a gasoline pump centrifugal. Water samples will be tested by a state certified laboratory on an annual basis for nitrate-nitrogen, ammonia-nitrogen, Kjedahl nitrogen, total phosphorus, chloride, specific conductance and volatile organic compounds (see separate current listing). Results are to be reported to the Marshfield Board of Health and shall meet Massachusetts Class I ground water standards and appropriate advisory levels for organic chemicals at the downgradient property boundary. Baseline samples of all applicable testing parameters will be required. In the event that water quality standards are violated, the following action will be undertaken by the septic system owner:
a. Report test results to the Marshfield Board of Health within 48 hours by certified mail
b. Resample and retest monitoring wells for the parameters which were above the water
quality standards within 5 days.
c. Notify the down gradient property owners who have a Private Drinking Water Well within 48 hours of the 2nd testing round, if the results are above the current advisory
levels, by certified mail.
d. Decrease wastewater flows or increase the level of treatment within 45 days. Notify the Board of Health of these remedial measures.
e. Initiate any remedial actions deemed necessary by the Board of Health.
f. All costs of complying with this section will be borne by the applicant.
SECTION 2.4 i PERIMETER, CURTAIN, SUBSURFACE OF FRENCH DRAINS
The effectiveness of a perimeter drain system must be demonstrated prior to the issuance of the Disposal Works Construction Permit. The effect of attempting to lower the ground or perched water table shall be monitored by installation of at least one upgradient and one downgradient ground water monitoring well. The effectiveness of the underdrains shall be demonstrated by taking ground monitoring well readings one time during the month of March and one time during the month of April, for a period of two high water seasons. All ground water monitoring well readings must be observed by the Board's agent in order to be considered valid ground water readings. A separate fee will be charged for each site visit (see separate current fee schedule for site work by agent beyond inspection of
septic system charged per inspection).
A perimeter, french, subsurface or curtain drain shall not serve more than one lot and shall not be allowed on more than 3 sides of a lot. They shall not cause accumulated water to drain onto any abutting properties or public or private road. All work shall be performed at the applicant’s own expense and at their own risk. This monitoring does not guarantee issuance of the Disposal Works Construction Permit, either at the time of monitoring or at completion since the Board does not give conditional pre-approval in matters relative to sewage disposal.
In order to propose a perimeter, french, curtain, or subsurface drain system the ground water table in question must be perched in a relatively impermeable soil layer, have no vertical upward flux component and be moving in a well defined direction. If the drain meets these criteria then the drain must be placed upgradient of the proposed sewage system location, be of sufficient length and geometry to intercept all ground water affecting the location, be keyed into the impeding layer upon which the ground water is perched, and have a positive discharge to the surface or to soil from the location in question.
2.5.3 GENERAL POLICY
Any reconstruction, alteration or repair of a building to an extent of fifty (50) percent or more of the assessed value of the building shall be treated by this Board as new
construction, to which all Title 5 and Marshfield Board of Health Rules and Regulations
for the Disposal of Sanitary Sewage apply.
2.7.1 REPEALED JANUARY 24,1991
2.7.2 BUILDING ALTERATIONS (Add to SEC Title 5, Reg 2.7)
When an existing building or structure is to be altered or repaired to an extent of less than fifty (50) percent of the assessed value of the building before such alteration or repair and if such alteration or repair may cause or permit the building to discharge a greater volume of sewage than the sewage disposal system was originally designed to handle, Board of Health approval must be granted before a building permit, building alteration permit, or plumbing permit is issued. As a condition of approval, the Board of Health may require extensive alterations to the existing sewage disposal system including such as would bring such facility into compliance with SEC Title 5 and these rules and regulations. If the Board of Health requires such alteration to the sewage disposal facility, no building permit shall be
issued until a DISPOSAL WORKS CONSTRUCTION PERMIT has been issued by the Board of Health. If the sewage disposal facility cannot be brought into conformity with SEC Title 5 and these rules and regulations to meet the needs of the proposed building alteration, the Board of Health may disapprove the application. If the application is disapproved, the proposed building alteration shall not be made and no building permit, building alteration permit, or plumbing permit shall be issued.
2.9 FEES (Supplements SEC Title 5, Reg. 2.9)
See separate current fee schedule.
2.13 VOLUME OF SANITARY SEWAGE (Modifies SEC Title 5, Reg. 2.13)
All sewage flows shall be determined by SEC Title 5 except that the estimated total flow for any residence, apartment, cottage, rooming house, motel, or boarding house will be a minimum of 400 gallons per day.
2.23 All sewage disposal systems must be located in their entirety on one lot or parcel of land, it being the same lot or parcel on which the facility producing the sewage is located.
SECTION 3 LOCATION
3.3 SUBSOIL AND GROUND WATER DETERMINATION (adds to SEC Title 5, Reg. 3.3)
The Board of Health shall require that one or more observation pits be dug to a depth of four feet below the bottom of the proposed leaching facility to determine the maximum ground water elevation and the elevation of any impervious material. The Board may also require additional test holes in the area reserved for expansion of the disposal field. In soils where maximum ground water levels are close to ground surface as determined by the Board of Health from such sources as the U.S. Soil Conservation Service Survey of Plymouth County, or other expert sources, or from past experience of the Board of Health, the Board of Health shall require either: (1) that the maximum ground water level determination be made during the wettest season of the year, normally March and April or (2) that allowance be made for a
high water level if the Board of Health permits the determination to be made outside the wettest season.
3.4 E LEACHING REQUIREMENTS:
