15 MIDSIZED SUBSURFACE SEWAGE TREATMENT SYSTEMS 7081.0200 <br />C. site conditions affecting system layout, distribution system requirements, and <br />constructability; <br />D. layers of coarse soil textures that affect treatment; <br />E. disturbed, compacted, cut -filled, or other unnatural condition, if present; <br />F. the uniformity of the soil over the site; <br />G. future surrounding land use changes; <br />H. soil sizing factor or loading rate; and <br />I. an approximation of the rise in groundwater from system operation as determined by <br />groundwater mounding calculations. A narrative evaluation of the accuracy of the approximation must be <br />provided. The approximation must be related to the requirements in part 7081.0270, subpart 6. <br />Subp. 2. Flood fringes. Systems proposed to be located in flood fringes must determine feasibility <br />of relocating the system outside the floodplain. <br />Subp. 3. Depth. The limiting layer in the soil shall be determined based on the depth of bedrock or <br />periodically saturated soil if encountered. The depth to the periodically saturated soil shall be determined <br />according to part 7080.1720, subpart 5, item E, and the depth of bedrock shall be as defined under part <br />7080.1100, subpart 8. <br />Statutory Authority: MS s 115.03; 115.55 <br />History: 32 SR 1400 <br />Published Electronically: March 11, 2011 <br />7081.0190 SITE PROTECTION. <br />The proposed soil treatment and dispersal area must be protected from disturbance, compaction, or <br />other damage by staking, fencing, posting, or other effective method. <br />Statutory Authority: MS s 115.03; 115.55 <br />History: 32 SR 1400 <br />Published Electronically: March 11, 2011 <br />7081.0200 SOIL AND SITE REPORT. <br />All information required in parts 7081.0150 to 7081.0180 must be submitted for review and approval <br />by the local unit of government prior to final design. The submittal must also contain: <br />A. a map of the proposed soil dispersal area, drawn to scale, showing: <br />(1) features with a setback within 150 feet of the system; <br />(2) easements within 50 feet of the system; <br />(3) <br />(4) <br />(5) <br />floodplains, wetlands, and surface waters, within 100 feet of the system; <br />location and elevation of all soil pits, borings, and hydraulic tests; and <br />two -foot contour lines; <br />B. dates and weather conditions during the field evaluation; <br />Copyright ©2014 by the Rev <br />so <br />of Statutes, State of Minnesota.
