DiProspero Jr. Vice President Sealand Contractors Corporation 1708 N. Caldwell Street Charlotte, NC 28206 Prepared By: Thompson 1 Environmental Consulting 41"- Thompson Environmental Consulting, Inc. PO Box 541 Midland, NC 28107 June 22, 2019 0 SOIL sir INTRODUCTION & SITE DESCRIPTION This Soil and Site Evaluation was performed on a portion of a 24.43-acre tract located at 501 NC 24- 27, Midland, North Carolina (Cabarrus County Tax Parcel: 55248739280000). Thompson Environmental Consulting, Inc. (TEC) was retained to determine areas that are suitable for placement of an onsite subsurface wastewater septic system for a commercial application. The property was evaluated in accordance with North Carolina statutes for waste disposal ("Laws and Rules for Sewage Treatment and Disposal Systems", amended December 2018). INVESTIGATION METHODOLOGY & SITE PHYSICAL CHARACTERISTICS Individual borings were advanced with a hand-held auger, and soil color was determined with a Munsell Soil Color Chart. Observations of the landscape (slope, drainage patterns, etc.) as well as soil properties (depth, texture, structure, seasonal wetness, restrictive horizons, etc.) were recorded. A portion of the project study area is currently being graded and erosion control measures have been installed. A single jurisdictional stream flows from northwest to southeast through the parcel. The undisturbed areas are vegetated with mixed deciduous forest. FINDINGS A field survey was conducted on June 11, 2019 by Larry Thompson, LSS. Eleven soil borings were evaluated, and their locations noted on the attached map. All borings, except for Borings 1 and 2, were rated as Provisionally Suitable for Subsurface Drip Dispersal. Surfaces typically exhibited a friable sandy clay loam texture with moderate, medium, subangular blocky structure 7 to 10 inches in depth. Upper subsurface horizons exhibited firm clay textures with moderate, medium, subangular blocky structure ranging in depth from 15 to 22 inches before encountering expansive clay mineralogy. A long-term acceptance rates (LTAR) for these soils would typically range from 0.08 to 0.1 gal/day/sgft. To confirm the presence of unsuitable clay mineralogy, TEC collected a representative soil sample for Apparent Cation Exchange Capacity (ACEC) testing, the results of which are attached to this report. The ACEC was calculated to be 22.18 (cmol/kg), which is higher than the 16.3 (cmol/kg) limit for expansive clay mineralogy. DISCUSSION Based upon TEC's soil and site evaluation, the area comprising Soil Borings 3-11 have the potential to support the installation of a pre-treated drip dispersal system. Approximately 13,000 to 16,000 square feet of suitable soil would typically need to be allocated and completely available for a subsurface drip dispersal system serving a business with 25-employees (625 gallons per day water usage). Additional soil work (special hydraulic assessment) would be required to substantiate the site LTAR and referenced square footage requirements. In addition to a special hydraulic assessment, the county will require a site -specific drip dispersal design to be completed and submitted for review 501 NC 24-27 1 June 22, 2019 Soil and Site Evaluation prior to a septic permit being issued. TEC would be pleased to provide a written cost proposal to perform part, or all, of the required testing and design work to obtain a septic permit for this property. CONCLUSION The findings presented herein represent TEC's professional opinion based on this Soil and Site Evaluation and knowledge of the current laws and rules governing on -site wastewater systems in North Carolina. Soils naturally change across a landscape and contain many inclusions. As such, attempts to quantify them are not always precise and exact. Due to this inherent variability of soils and the subjectivity when determining limiting factors, there is no guarantee that a regulating authority will agree with the findings of this report. This report does not guarantee or represent approval or issuance of an Improvement Permit, which can only be authorized by the Cabarrus Health Alliance. 501 NC 24-27 2 June 22, 2019 Soil and Site Evaluation TP11111" AL i dA \ i % its ` �= 04 Date: Soil and Site Evaluation June 2019 Figure Thompson Prepared For: Scale: 0 150 300 ft Environment* Consulting Sealand 501 NC 24-27 Contractors Midland NC 28107 EC Job #: Cabarus County, North Carolina 19-101 Thompson Environmental Consulting, Inc.

E 3P o 2 i l j ii - Updated February 2014 Apparent Cation Exchange Capacity to Determine Clay Mineralogy "Apparent Cation Exchange Capacity" (ACEC) means the sum of exchangeable bases plus total soil acidity at a pH of 7.0. ACEC is expressed in milliequivalents per 100 grams of soil (meq/100g of soil) or centimoles per kilogram of soil (cmols/kg of soil). The apparent soil ACEC is calculated by determining the ACEC using the neutral normal ammonium acetate method, pH of 7.0 neutral normal, and then dividing by the percent clay as determined by particle size distribution (pipette method) and then multiplying by 100, as described in USDA-NRCS Soil Survey Laboratory Information Manual, Soil Survey Investigations Report No. 45 and Kellogg Soil Survey Laboratory Methods Manual, Soil Survey Investigation Report No. 42. Laboratory testing of ACEC may be substituted for field testing to determine clay 5 mineralogy. The laboratory testing shall be conducted in accordance with Kellogg Soil 6 Survey Laboratory Methods Manual, Soil Survey Investigation Report No. 42, page 229, 7 or EPA Method 9080. Table VII shall be used to determine the clay mineralogy suitability 8 when laboratory testing is used. When using laboratory testing to determine clay 9 mineralogy, the clay content of the soil must be greater than 35 percent and the organic 10 matter component must be less than 0.5 percent.
