NLS§3.3, SSS§ 5.3. Table I below summarizes the surface and subsurface soil characteristics <br /> �,?)> tested from the two soil samples: <br /> `��� TABLE 1 <br /> SOIL PROFILE CHARACTERISTICS AND <br /> ANALYTICAL TEST RESULTS <br /> SAMPLE LOCATION, SOIL CLASSIFICATION SOIL NITROGEN PH AND <br /> SAMPLE DEPTH AND CONTENT CATION EXCHANGE <br /> (SAMPLE NUMBER) CAPACITY <br /> DISPOSAL AREA <br /> 42 INCHES DEPTH Clayey,Fine Sandy Silt 8 ppm NO,-N 7.2 22.3 meq/100g <br /> (42 IN) <br /> DISPOSAL AREA <br /> 24.75 FEET DEPTH Clay 15 ppm NO-N <br /> ( y 7.3 27.8 meq/100g <br /> 24') <br /> C. PERCOLATION TEST RESULTS <br /> SSS§ 6.2. To assess the permeability capabilities of the proposed disposal area, two "EHD Official" <br /> percolation tests and one"EHD Unofficial"percolation test were completed in the locations depicted <br /> in the Site Plan found in Appendix D. The"official"test depths were 42 inches and 24.75 ft below <br /> existing grade in the primary disposal area. The "unofficial"test was completed at the 8 ft depth in l <br /> the future stormwater retention basin area. <br /> SSS§6.3. On June 9, 2012,the test borings were drilled in the referenced locations. The sidewalls <br /> of each boring were scored with a pry-bar to open potentially smeared sidewalls, except for the deep <br /> test boring. Two inches of fine gravel was placed at the bottom and three-inch perforated PVC pipe (6. <br /> was inserted in each test boring. The test borings were pre-saturated with 36 inches of water at 0900 <br /> hrs, 48 hrs before the start of testing. <br /> SSS§ 6.4, 6.5. On June 11, 2012, percolation testing commenced for all three test borings <br /> referenced above. No standing water was observed after the soak period in the test borings. .tF� <br /> Consequently, EHD Perc Test Procedure#2 was conducted in which testing was done over a four- <br /> hour period to induce maximum soil saturation. The test results indicate a passing perc rate of 31.5 C�0 <br /> min/in for the 42 inch deep test boring,a failing rate of 50.0 min/in for the 24.75 ft test boring, and <br /> an excellent perc rate of 9.7 min/in for the 8 ft test depth. The minimum passing rate for tests less <br /> than eight ft deep is 60 min/in. For test depths greater than eight ft deep, the minimum passing rate <br /> is 30 min/in. <br /> A summary of the perc test results for the proposed disposal area with corresponding application \ <br /> rates in gallons of effluent accepted per square foot of soil,per day are found in Table 2 and Table 3: <br /> (5a5 4_77jlyd P3ZL /24-7& rllfbll) <br /> 4 <br />
