NR 207.04(1)(c)1.f.f. The discharger will be providing economic or social benefit to the community.
NR 207.04(1)(c)1.g.g. The discharger will be correcting an environmental or public health problem.
NR 207.04(1)(d)(d) If the new or increased discharge is found to result in a significant lowering of water quality or if the person proposing the new or increased discharge has waived the procedure in s. NR 207.05 (2) (a) to (d), the permit applicant shall demonstrate the following:
NR 207.04(1)(d)1.1. The proposed significant lowering of water quality cannot be prevented in a cost effective manner by the following types of pollution control alternatives:
NR 207.04(1)(d)1.a.a. Use of conservation measures.
NR 207.04(1)(d)1.b.b. Use of recycling measures.
NR 207.04(1)(d)1.c.c. Use of other applicable wastewater treatment process or operational changes.
NR 207.04(1)(d)1.d.d. Use of source reduction measures.
NR 207.04(1)(d)1.e.e. Use of other pollution minimization alternatives.
NR 207.04(1)(d)2.2. For proposals involving the expansion of a wastewater treatment plant, whether or not there are alternative wastewater treatment technologies which:
NR 207.04(1)(d)2.a.a. Have documented performance levels for similar wastewater composition,
NR 207.04(1)(d)2.b.b. Have capital costs less than 110% of the capital costs (or present worth less than 115% of the related total present worth value) for alternatives achieving the water quality based effluent limitations or the effluent limitations determined pursuant to chs. NR 200 to 297, as appropriate, and
NR 207.04(1)(d)2.c.c. Would prevent a significant lowering of water quality.
NR 207.04(1)(d)3.3. Whether or not there are other discharge locations or alternatives which would meet the conditions of subd. 2. b. and c.
NR 207.04(1)(d)4.4. Any other information required by the department or believed by the applicant to be necessary to complete review of the application.
NR 207.04 NoteNote: It is the intent of the department that, where possible, an applicant may use applicable information contained in a facility plan approved by the department to meet the requirements of s. NR 207.04 (1) (a) 1.a. to f..
NR 207.04(2)(2)Department determinations.
NR 207.04(2)(a)(a) If the department determines that the existing wastewater treatment facilities have treatment capability to treat any proposed new or increased discharge and maintain treatment levels sufficient to meet existing effluent limitations as documented under sub. (1) (a), effluent limitations will remain unchanged.
NR 207.04(2)(b)(b) If the department determines that the existing treatment facilities do not have treatment capability to treat any proposed new or increased discharge and maintain treatment levels sufficient to meet existing effluent limitations, effluent limitations will be developed using the following procedures:
NR 207.04(2)(b)1.1. If the proposed new or increased discharge will not significantly lower water quality as determined under s. NR 207.05 (4) and will accommodate important economic and social development as documented under sub. (1) (c), water quality based effluent limitations will be determined based on applicable procedures and criteria in chs. NR 102, 103, 105 and 106 or on categorical effluent limitation procedures pursuant to chs. NR 200 to 297 as appropriate.
NR 207.04(2)(b)2.2. If the proposed new or increased discharge will not significantly lower water quality as determined under s. NR 207.05 (4) and will not accommodate important economic and social development as documented under sub. (1) (c), water quality based effluent limitations for substances in the new or increased discharge will be set equal to the existing levels of these substances upstream of, or adjacent to, the discharge site.
NR 207.04(2)(b)3.3. If the proposed new or increased discharge will significantly lower water quality as determined under s. NR 207.05 (4), or the applicant has chosen to waive the procedure in s. NR 207.05 (2) (a) to (d), and the proposed discharge will not accommodate important economic and social development as documented under sub. (1) (c), water quality based effluent limitations for substances in the new or increased discharge will be set equal to the existing levels of these substances upstream of, or adjacent to, the discharge site.
NR 207.04(2)(b)4.4. If the proposed new or increased discharge will significantly lower water quality as determined under s. NR 207.05 (4), or the applicant has chosen to waive the procedure in s. NR 207.05 (2) (a) to (d), and the proposed discharge will accommodate important economic and social development as documented under sub. (1) (c), effluent limitations for the proposed new or increased discharge will be determined using the procedure in par. (c).
NR 207.04 NoteNote: When assessing existing treatment capabilities, it is the intent of the department to consider projected increases in a permittee’s discharge due to a planned water conservation project.
NR 207.04(2)(c)(c) The department shall use the following procedures to determine water quality based effluent limitations or effluent limitations determined pursuant to chs. NR 200 to 297 as appropriate, for each substance in the proposed new or increased discharge for which the existing levels upstream of, or adjacent to, the discharge site are of better quality than applicable water quality criteria or secondary values derived according to ch. NR 102, 103 or 105:
NR 207.04(2)(c)1.1. If there are no applicable pollution control alternatives or alternative discharge locations which meet the conditions of sub. (1) (d) 2. or 3., effluent limitations will be determined for the new or increased portion of the discharge based on applicable procedures and criteria or secondary values derived according to chs. NR 102, 103, 105 and 106 or based on effluent limitations pursuant to chs. NR 200 to 297, as appropriate.
NR 207.04(2)(c)2.2. If there are applicable pollution control alternatives or alternative discharge locations which meet the conditions of sub. (1) (d) 2. or 3., water quality based effluent limitations will be determined for the new or increased portion of the discharge based on the applicable pollution control alternative or alternative discharge site which prevents the significant lowering of water quality.
NR 207.04(2)(c)3.3. For an increased discharge not involving expansion of a wastewater treatment plant:
NR 207.04(2)(c)3.a.a. If there are no demonstrated, cost effective pollution control alternatives which would prevent significant lowering of water quality as demonstrated under sub. (1) (d) 1., effluent limitations shall be determined pursuant to chs. NR 102 and 106 or chs. NR 200 to 297, as appropriate.
