Process wastewater performance standard:
The rule's performance standard requires that livestock producers have no significant discharge of process wastewater to waters of the state. Sources of greatest concern include feed storage leachate and milk house waste. Process wastewater discharge is of sufficient concern that USDA has developed technical standards for its management. Environmental aspects of milking center waste water and feed storage leachate, including waste characteristics and water quality impacts, are included in:

Modifications to the non-agricultural performance standards were developed with input from a technical advisory committee that met four times between October 2007 and February 2008. Changes to the protective areas performance standard are based on the department's Guidance for the Establishment of Protective Areas for Wetlands in Runoff Management Rules, Wisconsin Administrative Code NR 151 in the Waterway and Wetland Handbook, Ch. 10. Department staff gathered information from municipal engineers and conducted analyses under various scenarios using analytical models to provide information to the technical advisory committee including:
  analysis showing the impact of redevelopment on total suspended solids loads, recommendations and estimated costs for control practices,
  analysis of the infiltration performance standards modifications for different land uses.
Analysis and supporting documentation used to determine effect on small business
The department concluded that the revisions to chs. NR 151, 153 and 155 will result in additional compliance requirements for small businesses, but the rules will not result in additional reporting requirements for small businesses. Rather than mandate specific design standards, the rules either establish new performance standards or revise existing performance standards.
Compliance requirements for agricultural producers vary depending on the type of operation and the performance standard, but the revisions to the rules will not change the existing compliance requirements for agricultural operations. Under state law, compliance with the performance standards is not required for existing nonpoint agricultural facilities and practices unless cost sharing is made available for eligible costs. A less stringent compliance schedule is not included for agricultural producers because compliance is contingent on cost sharing and in many cases, it can take years for a county or the state to provide cost share money to a producer.
Agricultural producers who are in compliance with the existing nutrient management performance standard may already be in compliance with the new phosphorus index and tillage setback performance standards. A phosphorus reduction strategy is included in NRCS nutrient management technical standard 590 (Sept. 5, 2005). A phosphorus index of 6 or less is specified in the PI strategy in Criteria C, 2 of the technical standard. The concept of streambank integrity, as proposed through a tillage setback performance standard, is an assumption of the phosphorus index calculation, which estimates phosphorus delivery to the stream via overland flow, but not from bank erosion or other means that soil, manure or fertilizer might enter the stream from farming operations. In circumstances where the phosphorus index has been determined to be insufficient to achieve water quality standards in areas where an approved total maximum daily load (TMDL) has been approved, a higher level of pollution control may be required. An owner or operator in this situation would be required to implement BMPs designed to meet the load allocation in the TMDL.
The rule revisions will not change the schedules for compliance and reporting requirements for non-agricultural businesses. These requirements are the same as those specified in ch. NR 216. In determining whether non-agricultural small businesses can be exempted from the rules, the department concluded that because the requirements of ch. NR 151, Subchapter III are based on federal requirements the state cannot exempt those businesses. Also, the impacts from certain small business construction activities can have as large a water quality impact as from large businesses.
In determining the compliance and reporting effects, the department considered 1) the existing performance standards and prohibitions in ch. NR 151, 2) the requirements of NRCS technical standard 590 needed to meet the nutrient management performance standard, 3) assumptions contained in the Wisconsin Phosphorus Index, 4) compliance and reporting requirements under ch. NR 216, Subchapter II, 5) agreement with the department of commerce to regulate storm water discharges from commercial building sites under one permit, and 6) feedback from members of advisory committees that included small business owners and organizations.
Small Business Impact (including how this rule will be enforced)
The overall effect on small businesses may be increased time, labor and money spent on BMPs or planning tools, but there will not be a significant economic impact on small business. However, for agricultural producers the proposed new agricultural performance standards and the revised existing agricultural performance standards are not enforceable unless 70 percent cost sharing is provided, or up to 90 percent for economic hardship cases. The rules will be enforced either through county ordinances, DNR stepped enforcement procedures or a combination of the two.
Small businesses in the construction industry will not see an effect from the changes to the construction performance standard, but may experience increased costs from the changes to some of the post-construction performance standards. Most of the businesses affected by the changes to the total suspended solids standard will be commercial and it is difficult to estimate how many of those would be classified as small businesses. The modifications to the infiltration and the protective area performance standards may add additional costs, but they are expected to be small. Businesses affected will be both large and small. The rule will be enforced through permits required under ch. NR 216, or through local ordinances. For the non-agricultural performance standards, cost sharing is not required for compliance. However, the department may award grants for certain BMPs and planning activities.
Initial regulatory flexibility analysis
Pursuant to s. 227.114, Stats., the proposed rule may have an impact on small businesses. The initial regulatory flexibility analysis is as follows:
Describe the type of small business that will be affected by the rule.
Agricultural producers (crops and livestock), business and associated professionals involved with construction (developers, engineers, contractors, others in the building profession, and small commercial establishments that meet the definition of small business).
Briefly explain the reporting, bookkeeping and other procedures required for compliance with the rule.
Describe the type of professional skills necessary for compliance with the rule.
Familiarity with software such as SNAP Plus and RUSLE2 will be needed for the phosphorus index agricultural performance standard.
Small business regulatory coordinator
The Department's Small Business Regulatory Coordinator for this rule may be contacted at or by calling (608) 264-9244.
Environmental Analysis
The Department has made a preliminary determination that this action does not involve significant adverse environmental effects and does not need an environmental analysis under ch. NR 150, Wis. Adm. Code. However, based on the comments received, the Department may prepare an environmental analysis before proceeding with the proposal. This environmental review document would summarize the Department's consideration of the impacts of the proposal and reasonable alternatives.
Fiscal Estimate
Proposed rule revision will result in an increased demand on agency staff devoting more time to training, education, grant oversight, enforcement and development of guidance and procedures. The department estimates that a total of 10.5 FTEs will be needed to implement all three rules.
State fiscal effect
Increase costs. Costs will not be absorbed within the agency's budget.
Local government fiscal effect
Increase costs.
Types of local governmental units affected
Towns, Villages, Cities, Counties.
Fund sources affected
Long-range fiscal implications
State cost-share grants to fully implement the process wastewater performance standard would be $9.3 million or $930,000 annually if awarded over a 10-year period. However, this estimate is dependent upon the availability of cost-share funds to implement the standard.

Explanation of agency authority
The Department has authority under ss 30.12, 30.19, 227.11, 281.11, 281.12, 281.15, 281.17, 281.41, 283.11, 283.13, 283.31, 283.37, 283.39, 283.49, and 283.55, Stats., to promulgate rules and clarify process.
Related statute or rule
These rules relate directly to regulation of activities in wastewater discharge permits or in navigable waters under ch. 30, Stats., waters designations in ch. NR 1, and the NR 100, 200, and 300 series rules.
Plain language analysis
The purpose of this rule update is to modify the existing rules to clarify, make consistent with federal regulations, clean up typographical errors, incorporate technology advances, or make minor modifications. The Bureau of Watershed Management has not undertaken the effort to clean up our rules and therefore this rule package is fairly large since several rules affect the Bureau and need to be updated and corrected.
NR 102 is the chapter that contains the listing waterbodies for outstanding or exceptional resource waters. There are several recommended pages of changes (13 pages in the ORDER). This code has primarily been changed to reflect typographical errors in the original listing of these waters, or if the water exists in more than one county, we have added the other county. To be consistent with the addition of two Wild Rivers to State Statute s. 30.26 in early 2009, language was refined and portions of these two existing ORW waters were moved to the Wild Rivers section of NR 102; however, this does not affect their status as ORW. With the exception of the 2009 statutory additions, there are no additions of new waterbodies, only corrections to the ones currently on the list.
NR 103 is the chapter that contains Water Quality Standards for Wetlands and the changes proposed are technical changes to reflect s. 281.36, Wis. Stat., a statute that was adopted after the rule went into effect.
NR 105 is the chapter that contains surface water quality criteria and secondary values for toxic substances. The changes requested for this chapter are typographical errors or values that have been updated because of new analytical methods. The changes to Table 9 in ch. NR 105 are done to reflect changes to Federal drinking water standards and are consistent with changes that were made in ch. NR 809. All other numerical changes are typographical errors.
NR 106 is the chapter which contains procedures for Calculating Water Quality Effluent Limits for substances discharged to surface waters. Changes to this chapter are primarily for clarification or typographical errors.
NR 108 is the chapter which outlines the Requirements for Plans and Specifications submittals for reviewable projects and operations of community water systems, sewerage systems and industrial wastewater facilities. The changes include technology updates requesting electronic submittals in addition to paper copies of final plans and specifications. To be consistent with federal regulations, the department proposes modification to s. NR 108.04 (5).
NR 110 is the chapter containing requirements for Sewerage Systems. Most of this rule package contains changes to this chapter, which needs to be updated primarily because of confusion on how to implement this rule (22 pages in the ORDER). Many changes are recommended to clarify the rule; other changes are because of technological updates. Revisions to this chapter are proposed to revise and clarify requirements for lift station design, influent and effluent flow monitoring, and to clarify language which has been commonly misunderstood. While these changes are voluminous, they reflect current practice and are not substantial, they are minor changes that make this rule more understandable and easier to implement. In 1997, the Department prepared draft code revisions for lift station requirements in ch. NR 110, and conducted a public hearing and obtained public comments. But the rule making effort was then placed on hold due to workload issues, and the code revision process was effectively terminated prior to promulgation. Many of the NR 110 code changes now being proposed were obtained from this 1997 work effort.
NR 114 is the chapter for Certification Requirements for Waterworks, Wastewater Treatment Plant, Septage Servicing and Water System Operations. Proposed changes to this chapter include adding a “Master Operator" category to the Septage Servicing subchapter II. This is a category that the stakeholders have asked for to develop a succession of responsibilities. This has been an issue for several years and this code change will help satisfy the needs of the stakeholders.
NR 200 is the chapter for Application for Discharge Permits and Water Quality Standards Variances. The proposed change to this rule is a technological update for the submission of permit applications on the web-based application system. The other changes are typographical or to be consistent with federal regulations.
NR 203 is the chapter for WPDES Public Participation Procedures. The proposed change to this code is to make it consistent with federal regulations.
NR 205 is the chapter for General Provisions in WPDES permits. The proposed technology update is to require electronic submission of discharge monitoring reports. Other changes are clarification of unscheduled bypassing of wastewater or to be consistent with federal regulations.
