Applicant's soil scientist field evaluates soil /site conditions within proposed drainfield and <br />repair area and prepares report which shall include the following (see note and item Ac= below <br />pertaining to need to inform LHD and OSWP Regional Soil Specialist when field work is <br />scheduled and to request for them to concurrently do any necessary verification of field work): <br />Soil profile descriptions which are legible (including information on slope, landscape <br />position, texture, structure, clay mineralogy, depth, wetness conditions, and restrictive <br />horizons) for pits or a combination of pits and soil borings made at each site for the <br />initial drainfield(s) and repair area(s). Site(s) shall be gridded and field staked at 50 <br />foot intervals to enable profile description locations to be identified in the field and on <br />the site plan. Intervals between profile descriptions and the relative use of borings <br />versus pits proposed to be made by the soil scientist shall be pre - approved by the LHD <br />with concurrence by the OSWP Regional Soil Specialist on a site specific basis. <br />Locations of pits and borings shall be shown on the site plan. <br />Delineation of sites which are suitable, provisionally suitable, or unsuitable for <br />different types of wastewater systems (e.g.: conventional, shallow conventional, LPP, <br />etc.) Delineate in sufficient detail on the site plan to enable location in the field. <br />Recommended LIAR for conventional, LPP, or other proposed system with justifying <br />references. <br />Soil /site -based recommendations for drainfield design and site modifications (e.g.: <br />maximum trench depth, fill depth, surface /subsurface drainage needs, etc.). <br />5. Soil /Site Evaluations continued: <br />Soil chemical data for sites proposed to receive wastewater from non - domestic <br />sources, ncluding pH, cation exchange capacity, percent base saturation and <br />background metal and cation (sodium, potassium, calcium and magnesium) levels, if <br />3 <br />
