(A) SSTS that were built before April 1, 1996, are outside of areas designated as shoreland and wellhead protection areas, and do not service a food, beverage, or lodging establishment, must have at least two feet of vertical separation between the bottom of the distribution media and the periodically saturated soil and/or bedrock. The vertical separation measurement must be made outside the area of system influence but in an area of similar soil.
(B) SSTS built after March 31, 1996 or SSTS located in a shoreland area, wellhead protection area, or serving a food, beverage, or lodging establishment as defined in Minn. Rules Chapter 7080.1100, subpart 84, must have three feet of vertical separation between the bottom of the distribution media and the periodically saturated soil and/or bedrock. The vertical separation measurement must be made outside the area of system influence but in an area of similar soil. Existing SSTS that have no more than a 15% reduction in this separation distance (a separation distance no less than 30.6 inches) to account for settling of sand or soil, normal variation of separation distance measurements, and interpretation of limiting layer characteristics, may be considered compliant under this chapter.
