				profile pit has been excavated within the boundaries of a proposed disposal
				trench or bed, the pit shall be backfilled after use in a manner that will not
				result in a major discontinuity with respect to soil horizonation, density or
				permeability in the soil below the disposal trench or bed.
3. When soil borings are substituted for the
				second profile pit these shall be located as shown in Figure 1 of Appendix A,
				at the approximate center of the disposal field and at corners opposite the

New Jersey Administrative Code › Title 7 - ENVIRONMENTAL PROTECTION › Chapter 9A - STANDARDS FOR INDIVIDUAL SUBSURFACE SEWAGE DISPOSAL SYSTEMS › Subchapter 5 - DETERMINATION OF SOIL SUITABILITY › Section 7:9A-5.3 - Terminology required for soil logs

Current through Register Vol. 56, No. 14, July 15, 2024
(a) A soil log
				shall be prepared for each soil profile pit or soil boring. The soil profile
				characteristics listed in
				7:9A-5.2(g)  shall
				be described using the terminology specified in (b) through (h)
				below.
(b) Depth and thickness of
				each district soil horizon or substratum shall be reported in inches. A
				distinct soil horizon or substratum is any soil horizon or substratum which
				differs from horizons or substrata above or below it in color, texture, coarse
				fragment content, mottling, structure or consistence.
(c) Color shall be described using the
				Munsell system of classification which includes a descriptive color name such
				as "strong brown" or "pale red", together with an alpha-numeric designation of
				hue, value and chroma such as "7.5 YR 5/6" or "2.5 YR 6/2". When mottling is
				encountered, report the dominant or background color and the mottle
				colors.
(d) Texture shall be
				reported as the name of the appropriate textural class which is shown on the
				USDA textural triangle, Figure 3 of Appendix A, determined based upon the
				relative proportions of sand, silt and clay in that portion of the soil which
				excludes the coarse fragment. Texture shall be estimated in the field by feel,
				or determined by textural analysis as prescribed in
				7:9A-6.3.
(e) The volume percentage of coarse fragments
				shall be estimated in the field visually using volume percentage estimation
				charts provided in Figure 4 of Appendix A. Coarse fragments which are rounded
				or subrounded in shape shall be classified based upon size, as indicated in
				(e)1 through 3 below. In the case of shale, slate, or other thin rock
				fragments, the rock type and the average length and thickness of the rock
				fragments shall be reported.
1. "Gravel"
				means a rock fragment from two millimeters (0.1 inches) to 76 millimeters
				(three inches) in diameter;
2.
				"Cobble" means a rock fragment from 76 millimeters (three inches) to 254
				millimeters (10 inches) in diameter; and
3. "Stone" means a rock fragment greater than
				254 millimeters (10 inches) in diameter.
New Jersey Administrative Code › Title 7 - ENVIRONMENTAL PROTECTION › Chapter 9A - STANDARDS FOR INDIVIDUAL SUBSURFACE SEWAGE DISPOSAL SYSTEMS › Subchapter 5 - DETERMINATION OF SOIL SUITABILITY › Section 7:9A-5.5 - Rock substrata

Current through Register Vol. 56, No. 14, July 15, 2024
(a) Criteria for
				recognition of rock substrata shall include but not be limited to the
				following:
1. Any solid and continuous body
				of rock, with or without fractures, or any weathered or broken body of rock
				fragments overlying a solid body of rock, in which more than 50 percent by
				volume of the rock fragments are greater than two-millimeters in diameter or
				large enough to be retained on a two millimeter sieve shall be considered to be
				a rock substratum. In cases where the content of coarse fragments increases
				downward in a soil profile underlain by a rock substratum, the upper limit of
				the limiting zone shall be taken as the depth above which 50 percent or more of
				the soil material consists of particles less than two millimeters in diameter
				or small enough to pass through a two millimeter sieve.
2. A rock substratum shall be considered as a
				fractured rock substratum if, based upon the judgment and experience of the
				soil evaluator, the rock substratum in question is determined to contain an
				adequate number of open and inter-connected fractures to allow unimpeded
				absorption of applied wastewater and transmission of this wastewater away from
				the disposal area. Any rock substratum which does not contain an adequate
				number of open and inter-connected fractures shall be considered a massive rock
				substratum. When doubt exists as to whether the limiting zone should be
				considered a fractured rock substratum or a massive rock substratum, the
				administrative authority may require a pit-bailing test or a basin flooding
				test to be performed as prescribed in N.J.A.C. 7:9A-6.
3. Whenever the presence of a perched zone of
				saturation, immediately above the rock substratum, is inferred based upon
				observation of soil morphology, as prescribed in
				7:9A-5.8, or confined, by direct
				observation or by testing, as prescribed in
				7:9A-5.9, the rock substratum shall
				be considered massive.

Current through Register Vol. 56, No. 14, July 15, 2024
(a) Criteria for
				recognition of excessively coarse horizons or substrata are as follows:
1. Soil horizons or substrata which have a
				coarse fragment content greater than 50 percent by volume shall be considered
				excessively coarse regardless of their measured permeability or percolation
				rate.
2. Sand textured soil
				horizons or substrata containing no greater than 50 percent coarse fragments by
				volume, and no less than 15 percent coarse fragments by volume (20 percent
				coarse fragments by weight), shall be considered excessively coarse if they are
				composed primarily of coarse-very coarse sand (from 0.5 to two millimeters in
				diameter) and lack detectable amounts (two percent or more) of silt and clay.
				Soils which lack detectable amounts of silt and clay are soils which are
				dominantly gritty to the touch, lack cohesion when moist, lack stickiness when
				wet and do not stain the fingers when rubbed in the hand.
3. When doubt exists as to whether a horizon
				or substratum should be considered excessively coarse, the administrative
				authority may require a soil permeability or percolation test to be performed
				within the horizon or substratum in question. Soil horizons or substrata which
				are tested shall be considered excessively coarse when the measured
				permeability is faster than 20 inches per hour or the measured percolation rate
				is faster than three minutes per inch. Alternatively, soil texture may be
				verified by textural analysis as prescribed in
				7:9A-6.3.

(a) Criteria for
				recognition of hydraulically restrictive horizons and substrata shall include
				but not be limited to the following:
1. Any
				soil horizon or substratum which exists immediately below a perched zone of
				saturation shall be considered hydraulically restrictive. The perched zone of
				saturation may be observed directly, inferred based on observation of soil
				profile morphology as prescribed in

				as prescribed in
				7:9A-5.9.
2. Any soil horizon or substratum possessing
				a clay, silty clay, or silty clay loam texture, as defined in the U.S.D.A.
				system of classification, shall be considered to be hydraulically
				restrictive.
3. Any soil horizon or
				substratum shall be considered hydraulically restrictive if it possesses a
				sandy clay, clay loam, silt loam or silt texture together with:
i. A massive or platy structure; or
ii. A hard, very hard, firm, very firm or
				extremely firm consistence.
4. Any cemented horizon or substratum such as
				ironstone, which remains hard even when soaked in water, shall be considered
				hydraulically restrictive.

Current through Register Vol. 56, No. 14, July 15, 2024
(a) When a hydraulic head test is required by
				the administrative authority to determine the presence or absence of a perched
				or artesian zone of saturation, piezometers shall be installed and monitored by
				the applicant as follows:
1. Piezometer A
				shall consist of a steel or plastic casing, a minimum of two inches in
				diameter, perforated or open at the bottom, and extending from above the ground
				surface to a point immediately above but not penetrating into the hydraulically
				restrictive horizon.
2. Piezometer
				B shall consist of a steel or plastic casing, a minimum of two inches in
				diameter located two to five feet from Piezometer A and extending from above
				the ground surface to a minimum of one foot below the bottom of the restrictive
				horizon. Piezometer B must be:
i. Open at the
				bottom or perforated only below the bottom of the restrictive horizon and
				within the underlying permeable horizon or stratum; and
ii. Installed or sealed in such a manner that
				no ground water may move upward or downward through the hydraulically
				restrictive horizon by flowing around the outside of the casing. When the
				hydraulically restrictive horizon is a horizon of high clay content and plastic
				consistence, this may be accomplished by use of a steel well-point which may be
				driven through the restrictive horizon and into the permeable soil below. In
				other cases, the piezometer shall be installed within an over-sized borehole
				with a bentonite pellet seal, a minimum of one foot thick, placed at the
				appropriate level.

2. Design permeability for
				all mounded disposal fields or soil replacement disposal fields where native
				soil will remain above the identified zone of disposal shall be determined from
				the remaining least permeable native soil material above the identified zone of
				disposal;
3. Design permeability
				for all soil replacement disposal fields, including mounded soil replacement
				systems, using fill material that meets the requirements of
				7:9A-10.1(f)  from
				the top of the zone of treatment to the top of zone of disposal shall be
				between six and 20 inches per hour; and
4. The permeability of all fill material
				shall be confirmed after installation to be greater than six inches per hour at

				fill material after it has been emplaced and compacted, or a tube permeameter
				test shall be conducted using samples of the fill material which have been
				compacted to a bulk density equivalent to that achieved in the construction of
				the disposal field. An additional test shall be required at the top of each
				separate type of fill, should the fill material in the zone of treatment differ
				from the fill material being used in the zone of disposal, to confirm each type
				of fill material has been installed with a permeability rate greater than six
				inches per hour.
