				nature, advanced wastewater pretreatment devices shall be from a manufacturer
				that has obtained an NSF Standard 40 and/or Standard 245 certification for the
				treatment technology, be certified by the manufacturer that the technology is
				designed to achieve secondary effluent standards for the actual or proposed
				waste strength that will be generated at the site and must be used in
				accordance with all requirements in this chapter. The Department shall maintain
				a list of advanced wastewater pretreatment devices that are applicable under
				this section that comply with the following:
1. Any advanced wastewater pretreatment
				device manufacturer that wishes to have their device listed by the Department
				shall submit a written request and a copy of an NSF Final Report. The written

UNIFORM PLACEMENT OF PERCOLATION TESTS
Uniform Placement of Percolation Tests
N.J.A.C. 7:9A-6.1(e)7
				 of these standards requires that percolation
				tests be spaced uniformly within the area of the disposal field. Acceptable
				patterns or arrangements for percolation test placement depend upon the size
				and shape of the disposal field as outlined below. Patterns other than those
				provided below may be approved provided that it is determined by the
				Administrative Authority that the test results submitted are representative of
				the soil conditions throughout the entire area of the disposal field.
Definitions
The following words and terms shall have the following meanings
				when used within Appendix B of this chapter:
"Center" means the intersection of the two disposal field
				diagonals.
"Diagonal" means a line connecting opposite corners of the
				disposal field.
"Elongated disposal field" means a disposal field with a
				length/width ratio of 3.0-5.0.
"End" means one of the two shorter sides in a disposal field
				which has a length/width ratio not equal to 1.0.
"Length" means the longest dimension of the disposal field, or
				the distance between the ends of the disposal field.
"Long axis" means a line connecting the midpoints of the
				disposal field ends.
"Rectangular disposal field" means a disposal field with a
				length/width ratio of 1.5-3.0.
"Side" means one of the two longer sides of a disposal field
				which has a length/width ratio not equal to 1.0.
"Square disposal field" means a disposal field with a
				length/width ratio of 1.0-1.5.
"Very elongated disposal field" means a disposal field with a
				length/width ratio greater than 5.0.
"Width" means the shortest dimension of the disposal field, or
				the distance between the sides of the disposal field.
A. When the disposal field is less than 1500
			 square feet, a minimum of two percolation tests are required and the following
			 arrangements are acceptable:
All Disposal Field Shapes
1. Both tests spaced along the long axis of
			 the field, the minimum distance between tests one third of the length of the
			 field.
2. Both tests spaced along
			 the diagonal of the field, the minimum distance between tests one third the
			 length of the diagonal.
