The purpose of this chapter is to establish the minimum requirements for evaluating and reporting soil and site characteristics that may affect treatment or dispersal of wastewater, treated wastewater, final effluent or nonwater-carried human wastes. SPS 385.01 HistoryHistory: Cr. Register, April, 2000, No. 532, eff. 7-1-00. SPS 385.02(1)(1) Pursuant to s. 145.02, Stats., this chapter applies to all soil and site evaluations conducted relative to the treatment or dispersal of wastewater, treated wastewater, final effluent or nonwater-carried human wastes into soil. SPS 385.02(2)(2) A department interpretation of the requirements in this chapter shall supersede any differing interpretation by a lower level jurisdiction. A department decision on the application of the requirements in this chapter shall supersede any differing decision by a lower level jurisdiction. SPS 385.02 NoteNote: A decision of the department may be appealed. Section 101.02 (6) (e), Stats., outlines the procedure for submitting requests to the department for appeal hearings and the department procedures for hearing appeals. SPS 385.02 HistoryHistory: Cr. Register, April, 2000, No. 532, eff. 7-1-00; CR 07-100: renum. to (1), cr. (2) Register September 2008 No. 633, eff. 10-1-08. SPS 385.10(1)(1) Soil evaluation. A soil evaluation for treatment or dispersal of wastewater, treated wastewater, final effluent or nonwater-carried human wastes regulated by chs. SPS 383 and 391 shall be performed by an individual who is a certified soil tester. A soil evaluation for the treatment or dispersal of stormwater regulated under ch. SPS 382 shall be performed by an individual who is either a certified soil tester or one who holds a professional soil scientist license under ch. GHSS 4. SPS 385.10 NoteNote: Section SPS 305.33 delineates the qualifications and certification procedures for certified soil testers. SPS 385.10(2)(2) Site evaluation. A site evaluation, relative to the installation of a POWTS treatment, holding or dispersal component location, or to determine land slope or setback distances to topographic or other site features shall be performed by a Wisconsin registered architect, professional engineer, designer of plumbing systems, designer of private sewage systems or land surveyor; a certified soil tester or POWTS inspector; or a licensed master plumber or master plumber-restricted service. SPS 385.10(3)(3) Soil saturation determinations. Soil saturation determinations may only be conducted and reported by an individual who is a certified soil tester. SPS 385.10 HistoryHistory: Cr. Register, April, 2000, No. 532, eff. 7-1-00; CR 04-035: am. (1) Register November 2004 No. 587, eff. 12-1-04; correction in (1) made under s. 13.92 (4) (b) 7., Stats., Register December 2011 No. 672. SPS 385.20(1)(a)(a) Soil boring methods and procedures shall comply with this section. SPS 385.20(1)(b)(b) Maximum soil application rates shall be determined relative to the soil texture, structure and consistence for each soil horizon or layer. SPS 385.20 NoteNote: Section SPS 383.44 establishes maximum soil application rates and soil treatment capability for the design of POWTS treatment or dispersal components consisting in part of in situ soil. SPS 385.20(2)(a)(a) General. The number, type, depth and location of soil profile evaluations shall be sufficient to delineate the area under investigation and to assure consistency of the data within that area. SPS 385.20(2)(b)1.a.a. Except as provided in subd. 1. d. and subd. 2., a minimum of 3 soil profile evaluation excavations shall be used to delineate a site within which POWTS treatment or dispersal components consisting in part of in situ soil are to be located. SPS 385.20(2)(b)1.b.b. For estimated daily flows of 1,000 gallons per day or less, at least one soil profile evaluation excavation per treatment or dispersal site shall be constructed as a soil pit, and described in accordance with s. SPS 385.30 (1) (c). SPS 385.20(2)(b)1.c.c. For estimated daily flows greater than 1,000 gallons per day, at least 3 soil profile evaluations per treatment or dispersal site shall be constructed as soil pits, and described in accordance with s. SPS 385.30 (1) (c). SPS 385.20(2)(b)1.d.d. The department or governmental unit may require additional soil profile evaluation excavations to be constructed where soil variability considerations may not be adequately addressed. The department or governmental unit may specify that soil profile descriptions in accordance with s. SPS 385.30 (1) (c) be conducted for any additional soil profile evaluation excavations. SPS 385.20(2)(b)2.2. At least one soil pit or soil boring shall be used to establish soil suitability for a pit privy. SPS 385.20(2)(c)1.1. Soil profile evaluations used to determine soil application rates shall be conducted using soil pits. SPS 385.20(2)(c)2.2. Soil profile evaluations used to determine or identify soil horizon depths, soil color, soil texture, redoximorphic feature colors or depth to groundwater or bedrock shall be conducted using either soil pits or soil borings. SPS 385.20(2)(d)(d) Depth. Soil profile evaluations shall extend an adequate depth below the land surface to identify soil properties critical to soil treatment or dispersal of wastewater, treated wastewater, final effluent or nonwater-carried human waste. SPS 385.20(3)(a)(a) Soil profile excavations. A soil profile excavation shall be of such size and construction to allow accurate determination of soil characteristics. SPS 385.20(3)(b)1.1. Soil borings shall be created by means of a soil bucket auger, soil probe, split-spoon sampler or Shelby tube having at least a 2 inch diameter. SPS 385.20(3)(c)(c) Soil pits. A soil pit shall be of adequate size, depth and construction to enable a person to safely enter and exit the pit and to complete a morphological soil profile description. SPS 385.20 NoteNote: Occupational safety and health administration regulations (29 CFR 1926, Subpart P) apply to certain types of excavations, and the persons entering such excavations need to be familiar with those regulations. SPS 385.20(4)(a)(a) Soil color evaluations shall be performed on days when light conditions permit accurate color determinations. SPS 385.20(4)(b)(b) Frozen soil material shall be thawed prior to conducting evaluations for soil color, texture, structure and consistence. SPS 385.20 HistoryHistory: Cr. Register, April, 2000, No. 532, eff. 7-1-00; correction in (2) (b) 1. b., c., d. made under s. 13.92 (4) (b) 7., Stats., Register December 2011 No. 672. SPS 385.30SPS 385.30 Soil profile description and interpretations. SPS 385.30(1)(a)(a) A soil profile description shall be prepared for each soil profile excavation constructed.
