Ch. PSC 4 Note Note: Chapter PSC 4 establishes procedures to provide the public service commission of Wisconsin with adequate information on the short-term and long-term environmental effects of its actions, as required by the Wisconsin Environmental Policy Act, ch. 274, section 1, laws of 1971 and s. 1.11, Stats.

PSC 4.05 PSC 4.05 Definitions. In this chapter:

PSC 4.05(1) (1) “Cogeneration facility” means a type of electric generation facility that simultaneously generates electrical power and useful heat from the same primary fuel source.

PSC 4.05(2) (2) “Commission” means the public service commission of Wisconsin.

PSC 4.05(2m) (2m) “Constructing an electric transmission line” means either of the following:

PSC 4.05(2m)(a) (a) Installing new conductors, insulators, and structures.

PSC 4.05(2m)(b) (b) Adding an additional circuit to an existing electric transmission line.

PSC 4.05(3) (3) “Distribution line” means an electric line whose main function is to deliver energy from a distribution substation to individual customers.

PSC 4.05(4) (4) “Distribution substation” means an electric substation whose primary function is to transform the voltage of incoming power to the primary distribution voltage.

PSC 4.05(5) (5) “Electric energy storage facility” means a supply facility that does not transform fuel or energy into electricity, but stores electricity or power capable of being transformed into electricity, including:

PSC 4.05(5)(a) (a) A magnetic energy storage system.

PSC 4.05(5)(b) (b) A battery.

PSC 4.05(5)(c) (c) Pumped water.

PSC 4.05(6) (6) “Electric generation facility” means a physical plant used for generating electrical power and includes multiple generating units installed over time as part of an overall development project. It also includes situations, such as wind farms, where multiple small generators are installed as part of a single, overall project. In the case of multiple units at a single site or proximate sites, the environmental review will be predicated on the total project rather than unit by unit.

PSC 4.05(9) (9) “Human environment” means the natural or physical environment and the relationship of people with that environment.

PSC 4.05(10) (10) “kV” means kilovolt.

PSC 4.05(11) (11) “MW” means megawatt.

PSC 4.05(12) (12) “Person” has the meaning specified in s. 990.01 (26), Stats. “Person” also includes the state of Wisconsin and its political subdivisions.

PSC 4.05(13) (13) “Rebuilding an electric transmission line” means modifying an existing electric transmission line to increase its capacity to carry current at the same voltage, including changing conductors, insulators or structures.

PSC 4.05(14) (14) “Scoping” means a process by which the commission requests other agencies and the public to help identify major environmental issues and how they will be addressed in an EIS.

PSC 4.05(15) (15) “Upgrading an electric transmission line” means modifying an existing electric transmission line to increase its capacity to carry current and increasing its voltage, including changing conductors, insulators or structures.

PSC 4.05(16) (16) “WEPA” means the Wisconsin Environmental Policy Act, chapter 274, section 1, laws of 1971, and s. 1.11, Stats.

PSC 4.05 History History: Cr. Register, July, 1995, No. 475, eff. 8-1-95; am. (1), (6), (9), (13) and (15), cr. (2m), Register, June, 2000, No. 534, eff. 7-1-00.

PSC 4.10 PSC 4.10 Categorizing commission actions.

PSC 4.10(1) (1) Type I actions. Type I actions are major actions that significantly affect the quality of the human environment, within the meaning of s. 1.11 (2) (c), Stats. The commission shall prepare an EIS on any of the proposed actions involving a request for commission approval, categorized as Type I actions, listed in Table 1. The commission shall also prepare an EIS for actions not listed in Table 1 that it determines are Type I actions.

PSC 4.10(2) (2) Type II Actions. Type II actions are proposed actions involving requests for commission approval that have the potential to significantly affect the quality of the human environment, within the meaning of s. 1.11 (2) (c), Stats. Unless the commission decides an EIS is necessary, the commission shall prepare an EA on any of the proposed actions involving a request for commission approval, categorized as Type II actions, listed in Table 2.

PSC 4.10(3) (3) Type III Actions. Type III actions are proposed actions involving requests for commission approval that normally do not have the potential to significantly affect the quality of the human environment, within the meaning of s. 1.11 (2) (c), Stats. As such, they do not normally require an EA or an EIS. An evaluation of a specific Type III proposal, however, may indicate that the preparation of an EA or EIS is warranted for that proposal. Type III actions are listed in Table 3.

PSC 4.10(3m) (3m) Actions not requiring environmental assessment.

PSC 4.10(3m)(a) (a) Commission actions not specified under sub. (2) do not normally require an environmental assessment except as otherwise determined by the commission under par. (b).

PSC 4.10(3m)(b) (b) Notwithstanding par. (a), the commission shall prepare an EA on a proposed action if it finds that:

PSC 4.10(3m)(b)1. 1. The action may be a major action significantly affecting the quality of the human environment within the meaning of s. 1.11 (2) (c), Stats., and that an EIS may be required; or

PSC 4.10(3m)(b)2. 2. The action involves unresolved conflicts concerning the use of available resources within the meaning of s. 1.11 (2) (e), Stats., such that the commission is required to study, develop and describe alternatives to the proposed action, and the commission has not studied, developed, and described alternatives in writing by other means.

PSC 4.10(4) (4) Categorizing transmission lines. If an electric transmission line is designed with a combination of the structure height and strength, line insulators, right-of-way and other elements that would allow the line to be easily modified to operate at a higher voltage than the initial operating voltage, the type of environmental review under this section is based on the line’s potential higher voltage level.

PSC 4.10(5) (5) Reasonable alternative proposals.

PSC 4.10(5)(a) (a) If a reasonable alternative to any proposed action specified in subs. (2) to (3m) exists, and the alternative would require review under sub. (1) as a Type I action, the proposed action shall be reviewed as a Type I action.

PSC 4.10(5)(b) (b) Unless par. (a) applies, if a reasonable alternative to any proposed action specified in subs. (3) to (3m) exists, and the alternative would require review under sub. (2) as a Type II action, the proposed action shall be reviewed under sub. (2) as a Type II action.

PSC 4.10 History History: Cr. Register, July, 1995, No. 475, eff. 8-1-95; am. (1) to (3), renum. (5) to be (5) (a) and am., cr. (5) (b), Register, June, 2000, No. 534, eff. 7-1-00.

PSC 4.20 PSC 4.20 Environmental assessment procedures.

PSC 4.20(1) (1) General information. The commission shall prepare an EA as a concise document that provides a factual investigation of the relevant areas of environmental concern in sufficient depth to permit a reasonably informed preliminary judgment of the environmental consequences of the proposed action. The EA shall include a recommendation whether the proposed action is a major action significantly affecting the quality of the human environment, within the meaning of s. 1.11 (2) (c), Stats., for which an EIS is required.

PSC 4.20(1m) (1m) Public notice. When it commences the preparation of an EA, the commission shall make a diligent effort to notify the public that an EA is being prepared. The announcement may be included with a notice of investigation or notice of hearing. The announcement shall describe the proposed action, including a map where appropriate, list a commission contact person and indicate how comments may be submitted. The announcement shall specify a public comment period lasting at least 10 days, beginning on the date the announcement is distributed. The commission shall distribute its announcement that an EA is being prepared to:
