Wis. Stat. § 1.11
The legislature authorizes and directs that, to the fullest extent possible:
Wis. Stat. § 1.11
The Wisconsin Environmental Protection Act, while not creating a public trust analogous to the public trust in the state's navigable waters, recognizes an interest sufficient to grant a person standing to question compliance with its provisions when it is alleged that agency action will harm the environment in the area where the person resides. Wisconsin's Environmental Decade, Inc. v. PSC, 69 Wis. 2d 1, 230 N.W.2d 243 (1975). Counties are not "agencies of the state" within meaning of sub. (2) (c). Robinson v. Kunach, 76 Wis. 2d 436, 251 N.W.2d 449 (1977). Sub. (2) (e) is applicable to proceedings involving authorization of priority systems for the curtailment of natural gas service. Wisconsin's Environmental Decade, Inc. v. PSC, 79 Wis. 2d 161, 255 N.W.2d 917 (1977). On judicial review of a state agency's decision not to prepare an environmental impact statement, the agency has the burden of producing a reviewable record reflecting a preliminary factual investigation into relevant areas of environmental concern and of showing a reasonable determination based on the same. Wisconsin's Environmental Decade, Inc. v. PSC, 79 Wis. 2d 409, 256 N.W.2d 149 (1977). The lack of a Department of Natural Resources (DNR) prepared environmental impact statement did not invalidate a DNR order to close a landfill site. Holtz & Krause, Inc. v. DNR, 85 Wis. 2d 198, 270 N.W.2d 409 (1978). The Department of Natural Resources' decision to limit the scope of a threshold decision to consideration of the impact of a segment of a proposed sewer interceptor was reasonable when the segment had: 1) independent utility; 2) a main purpose of fulfilling a local need; 3) logical termini; and 4) construction of the first segment did not compel construction of the second segment. Wisconsin's Environmental Decade, Inc. v. DNR, 94 Wis. 2d 263, 288 N.W.2d 168 (Ct. App. 1979). An agency determination that an environmental impact statement was adequately prepared is reviewed under s. 227.20 [now s. 227.57]. Wisconsin's Environmental Decade, Inc. v. PSC, 98 Wis. 2d 682, 298 N.W.2d 205 (Ct. App. 1980). The court erred in finding that this section applied to the Department of Industry, Labor and Human Relations' code compliance review procedure. Wisconsin's Environmental Decade, Inc. v. DILHR, 104 Wis. 2d 640, 312 N.W.2d 749 (1981). An order establishing depreciation rates for a utility's nuclear plant did not require an environmental impact statement. Wisconsin's Environmental Decade, Inc. v. PSC, 105 Wis. 2d 457, 313 N.W.2d 863 (Ct. App. 1981). Standing to challenge a final environmental impact statement requires that the agency decision directly cause injury to the interest of the petitioner, which must be an interest recognized by law. Fox v. DHSS, 112 Wis. 2d 514, 334 N.W.2d 532 (1983). An environmental impact statement is not required when the project will have minor impacts on the environment but will have possible socio-economic impacts. Wisconsin's Environmental Decade, Inc. v. DNR, 115 Wis. 2d 381, 340 N.W.2d 722 (1983). While the indirect secondary environmental effects may be influential in the content of an environmental impact statement, they are not necessarily controlling in determining the threshold question of whether an environmental impact statement is to be prepared. The presence of significant indirect effects or cumulative effects only increase the need for an environmental impact statement. Their presence alone does not require an environmental impact statement. Wisconsin's Environmental Decade, Inc. v. DNR, 115 Wis. 2d 381, 340 N.W.2d 722 (1983). Increased traffic congestion was a sufficient allegation of injury to acquire standing to challenge a final environmental impact statement. Milwaukee Brewers Baseball Club v. DHSS, 130 Wis. 2d 56, 387 N.W.2d 245 (1986). When a state action did not come within an action type listed in Department of Administration rules, an environmental assessment was required. A determination following an assessment that an environmental impact statement was not required for a building constructed for the state by a private developer under a lease/purchase agreement was reasonable under the circumstances. Larsen v. Munz Corp., 167 Wis. 2d 583, 482 N.W.2d 332 (1992). The test as to whether an environmental impact statement (EIS) should be conducted is one of reasonableness and good faith. When conditions for approval that compensate for any adverse environmental impacts are imposed, the statutory threshold of significant environmental impact is not crossed, and no EIS is required. State ex rel. Boehm v. DNR, 174 Wis. 2d 657, 497 N.W.2d 445 (1993). Section 227.42(1) does not grant a right to a contested case hearing regarding the need for an environmental impact statement. North Lake Management District v. DNR, 182 Wis. 2d 500, 513 N.W.2d 703 (Ct. App. 1994). When the legislature has selected a specific project site, consideration of alternative sites is too remote and speculative and not reasonably related to the proposed project. Shoreline Park Preservation, Inc. v. DOA, 195 Wis. 2d 750, 537 N.W.2d 388 (Ct. App. 1995), 94-2512. The burden of proving the adequacy of an environmental impact statement is discussed. Citizens' Utility Board v. PSC, 211 Wis. 2d 537, 565 N.W.2d 554 (Ct. App. 1997), 96-0867. It was reasonable to suspend the requirement for a draft environmental impact statement and the corresponding comment period when legislatively imposed time constraints could not have been met if they were not suspended. Responsible Use of Rural & Agricultural Land v. PSC, 2000 WI 129, 239 Wis. 2d 660, 619 N.W.2d 888, 99-2430. A court must assess an environmental impact statement (EIS) in light of the rule of reason, which requires an EIS to furnish only such information as appears to be reasonably necessary under the circumstances for evaluation of the project rather than to be so all-encompassing in scope that the task of preparing it would become either fruitless or well nigh impossible. While reasonable alternatives are to be considered, every potentiality need not be evaluated. Clean Wisconsin, Inc. v. PSC, 2005 WI 93, 282 Wis. 2d 250, 700 N.W.2d 768, 04-3179. The environmental impact statement is an informational tool that does not compel a particular decision by the agency or prevent the agency from concluding that other values outweigh the environmental consequences of a proposed action. Clean Wisconsin, Inc. v. PSC, 2005 WI 93, 282 Wis. 2d 250, 700 N.W.2d 768, 04-3179. Agency decision-making under the Wisconsin environmental policy act. 1977 WLR 111.
