7080.1100 INDIVIDUAL SUBSURFACE SEWAGE TREATMENT SYSTEMS 14 period while in the presence of a chemical inhibitor to block nitrification. CBOD is commonly expressed in milligrams per liter (mg/1). Subp. 13. Certificate of compliance. "Certificate of compliance" means a document, written after a compliance inspection, certifying that a system is in compliance with applicable requirements at the time of the inspection. Subp. 14. Certified statement. "Certified statement" means a statement signed by a certified individual, apprentice, or qualified employee under chapter 7083 certifying that the licensed business or qualified employee completed work in accordance with applicable requirements. Subp. 15. Cesspool. "Cesspool" means an underground pit, receptacle, or seepage tank that receives sewage directly from a building sewer and leaches sewage into the surrounding soil, bedrock, or other soil materials. Cesspools include sewage tanks that were designed to be watertight, but subsequently leak below the designed operating depth. Subp. 16. Clean sand. "Clean sand" means a soil fill material required to be used in mounds. The standards for clean sand are outlined in part 7080.2220, subpart 3, item C. Subp. 17. Commissioner. "Commissioner" means the commissioner of the Pollution Control Agency. Subp. 18. Compliance inspection. "Compliance inspection" means an evaluation, investigation, inspection, or other such process for the purpose of issuing a certificate of compliance or notice of noncompliance. Subp. 18a. Contour loading rate. "Contour loading rate" means the amount of effluent loaded to the soil per the length of the dispersal unit or units along the single hillslope along the contour. The contour loading rate is determined on the relationship between the vertical and horizontal water movement in the soil and is based on the permeability difference between the absorption area and any deeper horizons, the depth between the absorption area and the change in permeability, and the land slope. Subp. 19. Distinct. "Distinct" means a soil color that is not faint as described in subpart 29. Subp. 20. Distribution box. "Distribution box" means a device intended to distribute sewage tank effluent concurrently and equally by gravity to multiple segments of a soil dispersal system. Subp. 21. Distribution device. "Distribution device" means a device used to receive and transfer effluent from supply pipes to distribution pipes or downslope supply pipes, or both. These devices include, but are not limited to, drop boxes, valve boxes, distribution boxes, or manifolds. Subp. 22. Distribution medium. "Distribution medium" means the material used to provide void space in a dispersal component, through which effluent flows and is stored prior to infiltration. Distribution media includes, but is not limited to, drainfield rock, polystyrene beads, chambers, and gravelless pipe. Subp. 23. Distribution pipes. "Distribution pipes" means perforated pipes that distribute effluent within a distribution medium. Subp. 24. Drop box. "Drop box" means a distribution device used for the serial gravity application of sewage tank effluent to a soil dispersal system. Subp. 25. Dwelling. "Dwelling" means any building with provision for living, sanitary, and sleeping facilities. Copyright ©2014 by the Rev so of Statutes, State of Minnesota. All Rights Reserved.
