The site evaluation report shall include the following: <br /> a. Soil borings. At least three soil borings shall be completed for each new drainfield site <br /> designed. Each soil boring must be located within the drainfield site or within close <br /> proximity along similar contours such that similar soil conditions are likely. For additions to <br /> an ISTS, at least one soil boring shall be made in the expansion area. <br /> b. Percolation tests. At least two percolation tests shall be completed for each new drainfield <br /> site designed. Each percolation test must be located within the drainfield site or within <br /> close proximity along similar contours such that similar soil conditions are likely. For <br /> additions to existing ISTS's,at least one percolation test shall be completed in the expansion <br /> area. <br /> c. Plot plan. A scale drawing of the entire lot showing the following: <br /> 1. All property lines and lot dimensions. <br /> 2. AI► existing and proposed structures. <br /> 3. All existing or proposed well locations, or water supply piping. <br /> 4. Relative elevations of house, lot corners and drainfield areas. <br /> 5. Slope of ground at drainfield sites by contour lines or direction arrows and slope <br /> percentages. <br /> 6. Location of all percolation test holes and soil borings with identifying symbols and <br /> relative ground elevations of each. <br /> 7. Primary and alternate drainfield areas identified. <br /> 8. Distance from primary and alternate drainfield areas to property lines, well locations, <br /> and any lake, stream, marsh or drainage channel within 75 feet of any part of the <br /> system. <br /> (2) ISTS design. ISTS design specifications shall include proposed flows or other sizing information, <br /> minimum sewage tank capacity, minimum soil treatment area requirements, a plan of the <br /> component layout, and all other information necessary to assure the city that the ISTS is <br /> designed and will be constructed to receive, treat and dispose of all of the sewage from the <br /> building served. Footing or roof drainage, water softener recharge water,garage floor drainage, <br /> toxic chemicals, flammable liquids, animal wastes, commercial process water and commercial <br /> kitchen grease shall not enter any portion of the ISTS but shall be separately treated and <br /> disposed of according to the applicable regulations of the MPCA, the state board of health and <br /> the city. <br /> a.
