Chapter 283

283.15(4m) (4m) Variances for fish farms. In deciding whether to grant an application for a variance for a fish farm, the secretary shall rely on the same guidance documents and other information that would be used by the federal environmental protection agency to review and approve or disapprove the variance as required under 40 CFR 131.14.

283.15(5) (5) Conditions on variances.

283.15(5)(a) (a) A variance applies only to the permittee requesting the variance and to the pollutant specified in the variance. A variance does not affect or require the department to modify the corresponding water quality standard adopted under s. 281.15.

283.15(5)(b) (b) A variance applies for the term established by the secretary, but not to exceed 5 years. The term of the initial variance and any renewals thereof may not exceed the time that the secretary determines is necessary to achieve the water quality based effluent limitation. Initial and interim effluent limitations established under par. (c) 1. apply, as appropriate, for the term of the underlying permit as reissued or modified to implement the decision under sub. (4) (a) 1. or as extended by operation of s. 227.51 (2). Notwithstanding sub. (4) (d), s. 227.51 (2) shall apply for the purposes of continuing the provisions of a permit pending the reissuance of a permit.

283.15(5)(c) (c) The department shall require all of the following in a permit reissued or modified to implement a variance:

283.15(5)(c)1. 1. Compliance with an initial effluent limitation that at the time the variance is approved represents the level currently achievable by the permittee and that is no less stringent than the effluent limitation achieved under the permit before reissuance. At the time a variance is approved a compliance schedule and an interim effluent limitation that is achievable by the permittee during the term of the variance may be specified. The initial and the interim effluent limitations may not be less stringent than a categorical effluent limitation that applies to the permittee under s. 283.13 (2) or (4) or 283.19 or a toxic effluent standard that applies to the permittee under s. 283.21.

283.15(5)(c)2. 2. Investigation of treatment technologies, process changes, pollution prevention, wastewater reuse or other techniques that may result in compliance by the permittee with the water quality standard adopted under s. 281.15, and submission of reports on the investigations at such times as required by the department. The secretary shall modify or waive the requirements specified in this subdivision if the secretary determines, based upon comments received on the tentative decision under sub. (3), that the requirements of this subdivision are:

283.15(5)(c)2.a. a. Reasonably beyond the technical or financial capability of the permittee; or

283.15(5)(c)2.b. b. Unreasonable in light of the conditions specified in sub. (4) (a) 1. a. to e.

283.15(5)(d) (d) The department may impose conditions in the permit as necessary to administer the variance including, but not limited to, additional monitoring requirements.

283.15(6) (6) Renewal. A variance may not be renewed if the permittee did not submit the reports required under sub. (5) (c) 2. or substantially comply with all other conditions of the variance.

283.15(7) (7) Delegation of secretary’s authority. The secretary may designate an officer or employee of the department to make any decision that the secretary is required to make under this section.

283.15(8) (8) No right to a hearing. Notwithstanding s. 227.42, there is no right to a hearing under this section.

283.15(9) (9) Relation to permit review. If the secretary approves part or all of a variance or modifies and approves the variance under this section and the department issues a modified water quality based effluent limitation under s. 283.63 for the same substance, the permittee shall comply with the least stringent of the 2 effluent limitations.

283.15(10) (10) Applicability.

283.15(10)(a) (a) Subsections (2) to (5) do not apply if the water quality based effluent limitation results from the decision of the department under s. 283.63 to make the water quality based effluent limitation less stringent than the effluent limitation in the permit as issued, reissued or modified.

283.15(10)(b) (b) Subsections (2) to (5) apply if the water quality based effluent limitation results from the decision of the department under s. 283.63 to make the water quality based effluent limitation more stringent than the effluent limitation in the permit as issued, reissued or modified.

283.15(10)(c) (c) This section does not apply to the issuance, reissuance or modification of a permit to incorporate a toxic effluent standard or prohibition promulgated by rule under s. 283.11 (4) or 283.21.

283.15(11) (11) Water quality standards review. As part of the review of water quality standards under s. 281.15 (6), as required by 33 USC 1313 (c) (1), the department shall review the variances to water quality standards approved under s. 283.15 or 283.16. The department shall receive information regarding these variances at the public hearing held under s. 281.15 (6). If the department determines that a water quality standard to which a variance applies is attainable, the department shall modify the standard or variance accordingly at the time the permit containing the variance is reissued, modified, or revoked and reissued.

283.15(12) (12) Federal requirements. Notwithstanding any of the provisions of this section, the department shall comply with the provisions of 40 CFR 131.14 when approving and implementing a variance under this section.

283.16(3)(cm) (cm) If the department of administration decides under par. (c) that the determination remains accurate, the department of natural resources shall decide whether it is appropriate to apply more stringent effluent limitations than those in sub. (6) (a) to all point sources or to any category of point sources, based on the availability and cost effectiveness of technology for compliance and, if so, specify those more stringent effluent limitations based on the report under par. (a).

283.16(3)(d) (d) The department of administration shall provide public notice of its preliminary decisions under par. (c) no later than the 60th day after preparing the report under par. (a) and shall provide the opportunity for public comment on the decisions for at least 30 days following the public notice.

(6) (a), or any other effluent limitations that are in effect as a result of a previous review under this subsection or sub. (3), and determine whether they are consistent with the highest attainable condition for the point sources and categories of point sources that are eligible for the variance under this section. In conducting this review, the department shall use all existing and readily available information. The department shall hold a public hearing in order to receive additional information and public comment. The department shall publish notice of the hearing on the department’s Internet site at least 45 days before the hearing date.

283.16(3m)(b) (b) The department shall submit the results of a review under this subsection to the federal environmental protection agency within 30 days after determining that the review under par. (a) has been completed.

283.16(3m)(c) (c) If the department does not conduct a review within the time specified under par. (a), the variance under this section will cease to be available until the department completes the review and submits the results of the review to the federal environmental protection agency.

283.16(3m)(d) (d) If the department does not submit the results of a review to the federal environmental protection agency within the time specified under par. (b), the variance under this section will cease to be available until the department submits the results of the review to the federal environmental protection agency.

283.16(3m)(e) (e) In addition to the review under par.
