|
Time for testing. Except for tests in connection
with the alteration, without expenses or change in use, or repair
of existing systems, where any of the groundwater conditions identified
in Sections 5.8(b)(2)(v)(A) or (B) of this article are present, groundwater
elevations shall be determined only during the months of January through
April (unless the period is lengthened or shortened by NJDEP or by
the administrative authority due to a significant departure from normal
climatic conditions) and all such tests, whenever conducted, shall
be based upon the following:
[Amended 6-18-2003 by Ord. No. BH:03-01] | |||
i.
|
Profile pits. Water levels shall be measured
directly within soil profile pits. Profile pits shall be dug in natural
soil immediately outside of or within a fifteen-foot radius of the
proposed disposal system. The profile pits shall be a minimum of 10
feet in depth or to bedrock, but in no case shall the profile pit
extend less than eight feet below the bottom of the proposed level
of infiltration.
| |||
ii.
|
Size of profile pits. The profile pit shall
be of such size as to permit ready observation of earth material characteristics,
depth to seasonal high water table and depth to bedrock.
| |||
iii.
|
Groundwater tests. Groundwater tests shall be
conducted to provide evidence of the elevations of the regional zone
of saturation. Testing shall not be conducted until initial groundwater
stabilization is established over a period of not less than 24 hours
from the installation of the test equipment, using a test method to
be proposed by the applicant's engineer and witnessed by the administrative
authority or its authorized agent. Initial groundwater stabilization
shall not be considered reached where the last day's level is higher
in elevation than the previous day's. The usual method acceptable
to the administrative authority is by piezometers. However, monitoring
standpipes, installed vertically within the soil profile pits (after
which the pits are backfilled) are allowed.
| |||
iv.
|
Initial groundwater stabilization. Groundwater
testing shall be conducted after initial (twenty-four-hour) groundwater
stabilization is reached.
| |||
(A)
|
Favorable conditions. Where favorable groundwater
conditions exist [where none of the adverse criteria listed in Subsections
v(A) or (B), below, exist] on the lot (or proposed lot) being tested,
the groundwater testing shall be conducted for not less than 24 hours
after initial groundwater stabilization.
| |||
(B)
|
Moderate conditions. Where any of the groundwater
conditions set forth in Subsection v(A), below, are found to exist
anywhere on the lot (or proposed lot), testing shall be conducted
for not less than three business days, during the wet season, starting
after initial groundwater stabilization.
| |||
(C)
|
Severe conditions. Where any of the groundwater
conditions set forth in Subsection v(B), below, are found to exist
anywhere on the lot (or proposed lot), testing shall be conducted
weekly for eight consecutive weeks during the wet season (normally
during the months of January through April).
| |||
v.
|
The administrative authority will require monitoring
of the water table in addition to the testing described in Subsections
i through iv, above, when any of the following conditions are found
to exist:
| |||
(A)
|
Moderate conditions. The following groundwater
conditions shall require not less than three business days testing,
as set forth in Subsection iv(B) above:
| |||
(1)
|
The groundwater table at any time is observed
more than three feet and less than five feet of the surface of the
ground;
| |||
(2)
|
Where there is mottling observed within five
feet of the surface of the ground, unless meeting the definition of
perched as defined in 7:9A-5.8e.;
| |||
(3)
|
Where the Hunterdon County Soil Conservation
Service, County Soil Survey Report, shows groundwater to be within
five feet of the surface of the ground, and the on-site soil profile
description matches the description of the soil series in question
within the County Soil Survey Report; or the soil is rated as having
moderate to severe constraints for septic disposal, as determined
by the Soil Conservation Service in its Soil Survey Report, together
with a comparison of the soil series present at the site with the
soil series description contained in the County Soil Survey Report,
shall be provided by the applicant to the administrative authority;
or
| |||
(B)
|
Severe conditions. The following groundwater
conditions shall require testing weekly during eight consecutive weeks
of a wet season, as set forth in Subsection iv(C), above:
| |||
(1)
|
The groundwater table at any time is observed
within three feet of the surface of the ground;
| |||
(2)
|
Where there is mottling observed within three
feet of the surface of the ground, unless clearly and convincingly
shown to have been caused by a perched zone of saturation or meeting
the definition of perched according to 7:9A-5.8e.
| |||
(3)
|
Where the Hunterdon County Soil Conservation
Service, County Soil Survey Report shows groundwater to be within
three feet of the surface of the ground, or shows non-soil to be within
three feet of the surface of the ground, and the on-site soil profile
description matches the description of the soil series in question
within the County Soil Survey Report; or the soil is rated as having
"severe" constraints for septic disposal, as determined by the Soil
Conservation Service in its Soil Survey Report, together with a comparison
of the soil series present at the site with the soil series description
contained in the County Soil Survey Report, shall be provided by the
applicant to the administrative authority; or
| |||
(4)
|
Where there is a topographical feature, hydric
soils, or hydrophitic vegetation within 100 feet of the test site
that would indicate the likelihood of a high seasonal groundwater
(less than two feet from the surface of the ground).
| |||
(5)
|
Where an applicant believes that the period of testing required above should, for good cause, be shortened, and the applicant's engineer has certified that, in his or her professional opinion the results of testing conducted truly and accurately represent the seasonal high groundwater in the area, a request for a variation to shorten the testing period may be made by the applicant and considered by the administrative authority pursuant to the provisions of § 268-19 of this article.
| |||
(C)
|
Testing for moderate or severe conditions shall
not be discontinued when the groundwater levels for either of the
last two days of testing are higher in elevation than the average
daily groundwater levels of the previous days' testing.
| |||
vi.
|
In addition to the testing required by Subsections
iv and v, above, where the administrative authority has doubt concerning
an alleged perched formation or artesian formation, the applicant
may be required to perform hydraulic head testing during the months
of January through April for a minimum of eight consecutive weeks.
This hydraulic head test is to be conducted as prescribed by N.J.A.C.
7:9A-5.9. and read weekly over an eight-week period.
| |||
vii.
|
The administrative authority may suspend groundwater
testing if it is determined that there has been a significant departure
from normal climatic conditions. The administrative authority may
monitor the area climatic data, to establish a baseline for the determination
of abnormal climatic conditions.
| |||
viii.
|
All groundwater test results shall be certified
by a licensed professional engineer, and all testing shall be witnessed
by a representative of the administrative authority. Reports of the
depth to the referenced groundwaters shall be made on forms furnished
by the administrative authority.
| |||
ix.
|
All test piezometers and standpipes shall be
removed within 10 days after completion of the tests and approval
of the test results by the Board of Health, except where authorized
by the NJDEP for water quality testing. Extensions of time may be
granted upon written application to the administrative authority.
|
6.1(a) General provisions for permeability
testing.
| |
1.
|
The design permeability is the basis for determining
the minimum required area of the disposal field. Tests shall be required
at the site of each disposal field, at the level of infiltration,
for determination of the design permeability.
|
2.
|
Where what would otherwise be a conventional
disposal field meeting the requirements of Section 10.1(c) below will
be installed, tests shall be conducted at a depth of one foot to three
feet below the ground surface, within the soil horizon in which the
bottom of the disposal field will be placed. When a soil replacement,
mound, or mounded soil replacement installation is proposed, a minimum
of two percolation tests or more, meeting the number and placement
requirements shown in Appendix C of N.J.A.C. 7:9A, shall be conducted
at the level of infiltration after the fill material has been installed
and compacted.
|
3.
|
Fill material to be used in the zone of treatment
shall meet the coarse fragment content, textural analysis and permeability
requirements of N.J.A.C. 10.1(f)(4). Fill material to be used in the
zone of disposal shall meet the textural analysis and permeability
requirements of N.J.A.C. 10.1(f)(5).
|
4.
|
Fill material must be delivered and stockpiled
at the site for testing by a qualified soils laboratory and certified
by a licensed professional engineer of New Jersey, indicating the
coarse fragment content (where applicable), the textural analysis
and permeability rate of the material. At least one test for each
five truckloads (60 cubic yards) of material must be performed, with
a minimum of two samples per system. Fill materials not meeting the
requirements set forth in Subsection 6.1(a)3 above will have to be
replaced.
|
6.1(c) Soil permeability class rating.
|
---|
The soil permeability class rating test shall
not be used in soils which are predominantly clay, silty clay, silty
clay loam, sandy clay, clay loam, silt loam or silt, unless the results
of the test are confirmed by another type of permeability test permitted
by the Code. For further clarification on these restricted soil types,
reference is made to Appendix A, Figure 6, of N.J.A.C. 7:9A.
|
8.2(l)(3) Pretreatment units.
|
---|
An inspection port extending to finished grade
shall be provided over each tank or compartment inlet and outlet which
is not directly below a manhole, except for those where a septic solids
retainer is used. Inspection ports shall extend to finished grade,
shall be constructed of Schedule 40 Polyvinyl Chloride (PVC) pipe
designed for usage, among other uses, in a septic system, and shall
have a locked or bolted cap.
|
9.1 Pump septic systems.
| |
(a)
|
Automatically controlled electrically operated
pump septic systems ("pump systems") shall be permitted only if the
applicant is able to demonstrate to the administrative authority that
the topography of the property does not permit the installation of
a gravity system.
|
(b)
|
10.2(e). Disposal field sizing requirements.
|
---|
When soil tests taken in different part of the
disposal field yield different results, the system shall be designed
based upon the most restrictive conditions found within the area of
the disposal field. The minimum required disposal field bottom area
for soil replacement gravity or pressure dosing shall be 1.61 square
feet per gallon per day for disposal beds or trench systems.
|
The percentage by weight of fines and very fines
in the fill material to be installed in the zone of treatment or the
zone of disposal shall not exceed 25%.
|
10.1(i). Reserve area required.
| |
1.
|
No permit for the location and construction
of a new sewage/septic disposal system shall be issued unless the
applicant shall have obtained a minimum of two acceptable soil profile
pits and one acceptable permeability test in the primary area and
a minimum of two acceptable soil profile pits and one acceptable permeability
test in the reserve or replacement disposal area. The requirement
for a reserve area shall not apply to repairs, alterations, or replacements
of existing systems or to existing lots having an area of less than
1 1/2 acre.
|
2.
|
For subdivision purposes, all proposed subdivided
lots, including lands remaining that do not have a satisfactorily
operating septic system, shall have the required tests completed for
both the primary and the reserve areas and the test locations shall
be indicated on the sketch plat, except where the lot(s) in question
are deed-restricted to prevent development.
|
3.
|
There shall be a minimum of 30 feet between
fields for the primary area and the replacement area. The location
and spacing of tests for the primary and the reserve areas shall conform
with the requirements of N.J.A.C. 7:9A-5.2 as herein revised and as
shown on Figure 1 of Appendix A. The applicant shall designate on
the location survey which percolation or permeability tests and/or
soil profile pits are to be used for the primary area and which percolation
tests and/or soil profile pits are to be used for the expansion or
replacement area.
|
4.
|
The area of the reserve or replacement area
shall be equivalent to 100% of the proposed primary disposal area,
shall meet all the requirements applicable to the primary disposal
area and shall be outlined in the plans by a heavy dashed line marked
"Reserved for Disposal Area Expansion or Replacement." No improvements
or structures shall be installed or located within or adjacent to
this reserved area which may adversely affect its future use as disposal
area.
|
5.
|
The failure to provide a suitable and adequate
reserve and replacement area, where required, shall constitute sufficient
grounds for rejection of the application.
|
12.1 Advised inspection and maintenance.
| ||
(a)
|
A property owner having an individual septic
disposal system should have the system inspected by a licensed professional
engineering firm or a person or firm that commercially installs or
services septic systems (hereinafter "qualified professional") at
least every three years.
| |
(b)
|
The purpose of the inspection is to determine
whether the system is functioning satisfactorily and whether any preventive
maintenance is needed to prevent future failure. The inspection should
include the following:
| |
1.
|
Pumping of the septic tank to remove accumulated
solids and sludge.
| |
2.
|
Inspection of the septic tank for evidence of
leakage out of or into the unit, including visible holes, cracks,
or corrosion, or noticeable seepage of groundwater into the unit after
it has been pumped out; inspection for signs of clogging or effluent
backup indicated by a liquid level higher than the invert of the outlet.
| |
3.
|
Where access permits, inspection of the distribution
box for levelness, evidence of solids carry-over from the septic tank,
leakage out of or into the unit, including visible holes, cracks,
or corrosion, or noticeable seepage of groundwater into the unit,
signs of clogging or effluent backup indicated by a liquid level higher
than the invert of the outlets.
| |
4.
|
Inspection of the disposal field for signs of
hydraulic failure, including, but not limited to, ponding of rainwater
or effluent, surface breakout of effluent, wet or soggy soils conditions,
or sewage odor emanating from the area of the disposal field; condition
of surface grading and vegetation, evidence of uneven ground settlement,
slope failure, erosion or ruts caused by vehicular traffic; levels
of effluent ponding determined by means of inspection ports where
available; encroachments into the area of the disposal field, including
driveways, patios and other forms of encroachment which may affect
the operation of the system; and improperly directed drainage from
roofs, footing drains, ditches or swales, or any other unauthorized
source of hydraulic loading.
| |
(c)
|
This Section 12.1 is advisory in nature and
therefore no penalty is provided for the violation thereof.
