NR 204.06(2)(c)4.4. The amount of sludge per year which is actually land applied or landfilled shall determine the minimum monitoring frequency. If the applicable frequency of monitoring in subd. 3. is more than once per year, but land application is done only part of the year, the frequency of monitoring requirements may be reduced accordingly for nutrients, class B pathogen and vector attraction reduction requirements on a case-by-case basis in the permit by the department. Determinations shall be based on the facilities treatment process, the time of year land application occurs and the frequency at which the sludge is applied. In all cases, the intent is to have a representative analysis of the sludge which is actually being used. In all cases, the monitoring frequency indicated in subd. 3. for metals shall be adhered to, except as modified by subd. 5. NR 204.06(2)(c)5.5. After 2 years of monitoring at the frequencies specified in subds. 3. and 4., the monitoring frequencies may be reduced at the permittee’s request and subject to department approval.

NR 204.06(8)(d)(d) The producer or distributor of sludge distributed out-of-state shall notify the permitting authority of the receiving state of its intent to do so. This notification shall be given prior to the initial application of bulk sludge to the land application site by the applier. This allows sufficient time so that the permitting authority has the opportunity to determine whether a permit application or other appropriate oversight is needed. This notification shall be in writing and include the name, address, telephone number and permit number of the sludge supplier, and the specific location of the site, the approximate time the land application will occur and the name, address, telephone number and permit number, if appropriate, of the applier.

No person may land apply sludge in a manner which does not comply with the requirements of a WPDES permit and this chapter. NR 204.07(2)(2) Approved sites. The permittee shall obtain written or computer generated approval from the department for each site on which sludge is applied in bulk prior to land application, unless the permittee is authorized to inspect and approve their own sites under s. NR 204.06 (6). The department shall review and issue either approval, conditional approval or denial within 60 business days following receipt of the site’s complete application, unless weather conditions preclude adequate site evaluation. Each site shall be reviewed based on information contained in the report required by s. NR 204.06 (6). Failure to comply with the conditions of the site approval may result in the revocation of the approval and be considered a violation of the permit. Reapproval shall be contingent on submittal of an operations report for the site which shall specify how further violations will be avoided. When a permittee contracts with another party to land apply sludge and the land applier is not required to hold its own WPDES permit under s. NR 204.05, the permittee maintains responsibility, as well as the land applier, for compliance with the WPDES permit and this chapter. The permittee shall supply the land applier with all information necessary to ensure compliance. The land applier shall also make reasonable attempts to obtain all information needed to ensure compliance with this chapter. NR 204.07(3)(a)(a) Bulk sludge may not be applied to the land if it is likely to adversely affect a threatened or endangered species or its designated critical habitat, or a designated historical site.

NR 204.07(3)(c)(c) Bulk sludge may not be applied to soils with a high groundwater level or bedrock at a depth of less than 3 feet. Exceptions may be granted by the department on a case-by-case basis. Parameters which may be considered for exceptions include: demonstration that the soil has an available water holding capacity that is greater than 5 inches, above the high groundwater level or bedrock; whether the high groundwater is a seasonal condition; depth of saturation at the proposed time of application to determine whether a seasonal use approval may be granted and other relevant site specific conditions. NR 204.07(3)(d)(d) Bulk sludge may not be applied on sites with soils which have a rapid permeability of greater than 6 inches per hour unless, through consideration of the sludge characteristics, loading rate, cropping practices and other soil characteristics, department approval is obtained. NR 204.07(3)(e)(e) The pH of the soil shall be 5.5 or greater at the time the bulk sludge is applied, unless after consideration of the sludge quality, cropping practices and soil characteristics of the site, the department determines that the pH should be higher to protect the environment or public health. NR 204.07(3)(f)(f) If the soil at a site or field is classified as highly erodible on the United States department of agriculture’s county by county soil conservation service soil survey, the department may impose additional management practices, such as soil conservation practices, to minimize erosion from the site. NR 204.07(3)(g)(g) Class B sludge, as specified in sub. (6) (b), that is land applied to sites shall have restricted public access for a period of 30 days for low exposure sites such as a farm field, and one year for high exposure sites such as a city park, following sludge application. Access may be restricted by the location of the site on private property, fencing or posting the application site, or other department approved methods that minimize human contact with the sludge. NR 204.07(3)(h)(h) Bulk sludge shall be applied in a manner to minimize soil compaction, to prevent surface runoff and to control objectionable odors. Sludge may not be applied on saturated soils, during significant rainfall events or in areas with ponded water or to areas which are subject to ponding. NR 204.07(3)(i)(i) Bulk sludge land application vehicles or equipment shall be moving at all times while sludge is being applied to ensure uniform application. Uniform application shall be accomplished for surface application vehicles by the use of a splash plate, spreader bar, beaters, expellers or other department approved methods. NR 204.07(3)(j)(j) Bulk sludge transporting vehicles and equipment may not leak sludge during use, transport, operation or storage. Vehicles utilized for the land application of liquid sludge shall have cab actuated discharge valves. NR 204.07(3)(k)(k) Sludge which has a PCB concentration greater than 50 mg/kg (dry weight) may not be applied unless a management plan is approved by the U.S. EPA region V administrator pursuant to 40 CFR 761.60 (a) (5) (iii). Sludge with a PCB concentration greater than 10 mg/kg (dry weight) shall be injected or incorporated into the soil. NR 204.07(3)(L)(L) Application of bulk sludge, by any person, on frozen or snow covered ground is prohibited unless it is demonstrated, to the satisfaction of the department, that there are no other reasonable disposal methods available and there is absolutely no likelihood that the sludge will enter the waters of the state, or except as provided in par. (m). NR 204.07(3)(m)(m) Application of bulk sludge on frozen or snow covered soils may be approved by the department on a case-by-case basis until storage is available, as required in s. NR 204.10. Department approvals for application on frozen or snow covered soils shall require the following restrictions at a minimum: NR 204.07(3)(m)3.3. Application is not allowed within 750 feet of any surface water, wetland or floodplain. NR 204.07(3)(n)(n) When a WPDES permit requires testing for radium-226 and the sludge is subsequently found to contain radium-226, the land application of the sludge shall be terminated when the soil level of radium-226 equals or exceeds 2 pico curies per gram of soil on a dry weight basis in the top 12 inches of soil. In addition to other criteria in this section, the following conditions shall be adhered to when land applying sludge containing radium-226: NR 204.07(3)(n)1.1. The soil pH shall be at least 6.0 prior to the application of sludge containing radium-226. This pH shall be maintained during the period the site is used for the land application of sludge containing radium-226. NR 204.07(3)(n)2.2. The soil shall have at minimum a 6 inch layer with a clay content of at least 18% within the top 5 feet of the soil profile and be above the seasonal high groundwater level and bedrock. This determination shall be based primarily on the detailed county soil survey books. NR 204.07(3)(n)3.3. The soil shall have at minimum a 6 inch layer with an organic matter content of at least 12 tons/acre within the top 5 feet of soil and be above seasonal high groundwater or bedrock.
