Section NR 111.32 - Monitoring requirements The owner or operator of the facility shall complete all of the following monitoring to demonstrate compliance with the requirements specified in s. NR 111.31:
(1) The owner or operator of the facility shall comply with any monitoring requirements established by the department for impingement, impingement mortality, and entrainment of the commercial, recreational, and forage base fish and shellfish species identified in the source water baseline biological characterization data required under s. NR 111.41(3). Monitoring methods used shall be consistent with those used for the source water baseline biological characterization. If the department establishes such monitoring requirements, the frequency of monitoring and specific protocols shall be determined by the department.(2) The owner or operator of the facility shall conduct flow and velocity monitoring daily that is representative of the normal operating conditions of the date on which each sample is taken. Flow monitoring shall include measuring cooling water withdrawals, make-up water, and blowdown volume and shall be reported as a daily total volume. Velocity shall be reported as a daily maximum velocity. The department may require additional monitoring necessary to demonstrate compliance with s. NR 111.31.(3) An owner or operator of the facility complying with the option II requirements under s. NR 111.31(2) shall monitor to demonstrate achievement of reductions commensurate with a closed-cycle recirculating system. The owner or operator of the facility shall monitor entrainable organisms at a proximity to the intake that is representative of the entrainable organisms in the absence of the intake structure. The owner or operator of the facility shall also monitor the latent entrainment mortality in front of the intake structure. Mortality after passing the cooling water intake structure shall be counted as 100 percent mortality unless the owner or operator of the facility has demonstrated to the approval of the department that the mortality for each species is less than 100 percent. Monitoring shall be representative of the cooling water intake when the structure is in operation. In addition, sufficient samples shall be collected to allow for calculation of annual average entrainment levels of all life stages of fish and shellfish. Specific monitoring protocols and frequency of monitoring shall be determined by the department. The owner or operator of the facility shall follow the monitoring frequencies identified by the department for at least 2 years after the initial permit issuance. After that time, the department may approve a request for less frequent monitoring in the remaining years of the permit term and when a subsequent permit is reissued. The monitoring shall measure the total count of entrainable organisms or density of organisms, unless the department approves of a different metric for such measurements. In addition, the owner or operator of the facility shall monitor the actual flow withdrawn for each intake. The actual flow withdrawn shall be measured at the same time as collection of the samples of entrainable organisms. The department may require additional monitoring necessary to demonstrate compliance with s. NR 111.31.(4) The owner or operator of the facility shall comply with any additional monitoring for impingement or entrainment at the cooling water intake structure used by a new unit, including any of the following:(a) The department may require additional monitoring if there are changes in operating conditions at the facility or in the source waterbody that warrant a re-examination of the operational conditions specified in s. NR 111.41(7).(b) The department may require additional monitoring for species not subject to the BTA requirements for impingement mortality under s. NR 111.12. Such monitoring requirements shall be determined by the department on a site-specific basis.Wis. Admin. Code Department of Natural Resources NR 111.32
