Each additional page shall be clearly numbered. NR 113.12(3)(d)4.f.f. A design report that includes plans and specifications for all septage storage facilities. The design report shall show calculations used to design the septage storage facilities. The report shall show proof that the designer considered factors relevant in preparing the plans and specifications. Factors include all of the following: volume of septage, types of septage, screen for debris, degree or extent of mixing, any lime addition and mixing for meeting vector attraction reduction, sediment removal, odor controls, pumps for removal, and other factors as necessary to provide an adequate description of the storage facility. The design report shall be included with the submittal by a designer of engineering systems-plumbing, designer of engineering systems-private sewage, master plumber, master plumber restricted service, or professional engineer. NR 113.12(3)(d)4.g.g. A statement from the owner that indicates the tank is not part of a private onsite water treatment system that discharges to the waters of the state. NR 113.12(3)(e)(e) Delegation of review authority. The department may not delegate review authority for septage storage facilities to counties or other local governmental entities. NR 113.12 NoteNote: See ss. 281.41 and 281.48, Stats., and s. NR 113.10. Governmental units responsible for regulation of private onsite wastewater treatment systems as defined under s. 145.01 (5), Stats., do not possess the regulatory authority under s. 145.20, Stats., for septage storage as septage storage is not defined as a private onsite wastewater treatment system under s. NR 145.01 (12). NR 113.12(3)(f)(f) Proposed conversion of an existing storage facility to septage only storage facility. When an owner or operator of an existing non-septage storage facility proposes to convert the storage facility to septage only storage, the storage facility shall adhere to all of the following prior to use: NR 113.12(3)(f)1.1. The existing storage facility, after modifications if necessary, shall adhere to all of the requirements under ch. NR 110. NR 113.12(3)(f)2.2. The department may allow exemptions from ch. NR 110 design standards and materials requirements if all of the following conditions are met: NR 113.12(3)(f)2.a.a. The owner or operator can demonstrate that the design standards and material requirements are more stringent than necessary to comply with the provisions of ch. NR 140 and chs. 160 and 283, Stats. The owner or operator shall justify such an exemption from the design standards and material requirements by demonstrating the alternative design will not contribute to the exceedance of applicable groundwater and surface water standards. NR 113.12(3)(f)2.b.b. The department shall consider all of the following factors when reviewing an alternative design in consideration of granting an exemption: physical characteristics of the site, such as soil texture, soil permeability, depth to groundwater, and depth to and type of bedrock; age and condition of the existing structure; analytical data from existing groundwater monitoring wells or any wells that may be installed as part of the demonstration; the quantity and composition of the materials stored or treated at the facility; the compatibility between the materials stored or treated at the facility; proximity of storage to surface waters, secondary containment, and any other information relevant to the environmental impacts of the facility’s operations. NR 113.12(3)(f)3.3. The owner or operator of the storage facility may request an exemption from the design standards and material standards by submitting facts to support the exemption request to the department in the application for plans and specifications. NR 113.12(3)(f)5.5. Plans and specifications shall be submitted to the department for review and acceptance. NR 113.12(3)(f)6.6. Prior to use of the septage storage facility the owner or operator of the septage storage facility shall submit to the department all of the following: NR 113.12(3)(f)6.d.d. A report of department approved land application sites if disposal of septage will include land application. NR 113.12(3)(f)7.7. Prior to use, the owner or operator of the septage storage facility shall submit to the department a report indicating that any deficiencies identified in the conversion inspection report were corrected. NR 113.12(3)(g)(g) Proposed conversion of manure storage facility to a storage facility mixing septage with manure. When the owner or operator of an existing manure storage facility proposes to accept septage into the manure storage facility, all of the following requirements shall apply: NR 113.12(3)(g)1.1. Septage may not be stored in the manure storage facility if the storage facility is located under a building where animals are housed. NR 113.12 NoteNote: Section ATCP 65.22 (6) (c) prohibits the mixing of human waste or septage with animal manure on a dairy farm. NR 113.12(3)(g)4.4. The septage-manure mixture shall comply with the requirements under county land and water conservation ordinance requirements and local ordinance requirements together with all of the following requirements: NR 113.12(3)(g)4.a.a. The existing manure storage facility shall adhere to all applicable design standards and material requirements under U.S. department of agriculture, natural resources conservation service, code 313, NRCS standard 313, dated May 2016, or equivalent. The owner or operator of the manure storage facility shall collect records from the county land and water conservation department and submit those documents to the department for review and acceptance.
