Wisconsin River BOD TMDL Pilot -CO_1_CMP16

Purpose

The purpose of this pilot project is to collect data to develop dissolved oxygen model for Segment BC of the Wisconsin River.

Objective

The original BOD5 wasteload allocations for the Wisconsin River (WBIC 1179900) were developed in 1981 from a modeling effort that began in 1972. The wasteloads codified in s.NR 212. 60 Wis. Adm. Code have been modified four times since, with the latest change coming in 1988. The Department is required under s. NR212 to review wasteloads every 5 years and has not done so since 1988. As point sources seek additional wasteloads to increase industrial productivity and have compliance issues, the need for a dissolved oxygen new model has surfaced. A new model would redistribute the wasteload allocations while ensuring to 5mg/L DO standard is met. The project proposes to collect the relevant background data necessary to run the EPD-RIV1 model. Data will be collected at 14 locations on the Wisconsin River and 4 continuous stationary sampling points. Additionally, effluent samples will be collected and analyzed from 7 dischargers located within segment BC. The list of proposed dischargers is listed below: Permittee (WPDES #) Brokaw WWTF (002136) Wausau WWTF (0025739) Domtar Rothschild (0026042) Lignotech (0003450) Foremost Foods (0003875) Rib Mountain WWTF (0035581) Expera-Mosinee (0003671) Mosinee WWTF (0022390) Mullins Cheese (0054127) The final objective of this project will be to recommend the necessary data collection to create a Wisconsin River DO model from the Rhinelander Dam to the Castle Rock Dam. This data will be collected in subsequent sampling seasons. A comprehensive sampling plan is included as a separate document.

Outcome

A working EPD-RIV1 model and report will be prepared. The model will predict dissolved oxygen concentrations along a longitudinal profile of segment BC of the Wisconsin River. The anticipated report elements will include a summary of the data collected, calibration and sensitivity analysis of sampled model parameters, and recommendations for future data collection. Future data collection will be used to create a full Wisconsin River DO model and redistribute BOD5 wasteload allocations. Rule and guidance will be developed to reflect the process for sampling and modeling in the future. Preliminary projected cost of sampling for the complete model is $186,000. These methods may be applied to the Lower Fox and Peshtigo Rivers as the need arises. 1)Sample sites associated with project: 14 instream sites, 4 stationary sites, 9 point sources. 27 total sites. Details are explained further in the attached Study Design Section 2) Number of Sampling Events: 2 sampling events will be conducted during FY16. We anticipate sampling in late July and September 2016 3)Date of Completion: Sampling should be complete by September 2016 4) Data Entry: All Data will be entered into Databases by October 2016 5) Report: A Final Report will Be completed by December 2016 to allow for new sampling plans to be proposed. 6) Database: SWIMS 7)Data Entry: Central office staff will enter data
