TMDL

– Total Maximum Daily Load –

As of May 2024, Oregon DEQ published the Powder River Basin TMDL for E. Coli to address impairments of water quality due to pollutants identified as E. Coli. Subsequently, a Water Quality Management Plan (WQMP) was also published to outline the process for Designated Management Agencies (DMAs) to establish implementation plans for their designated portions of the Powder River Basin to which they contribute.

Among other cities, counties and organizations, the City of Baker City (City) has been listed as a DMA. Thus, the City will develop an implementation plan as required by the WQMP to identify strategies to address the influences of potential pollutant contribution to the section of the Powder River Basin under its legal authority within its city limits. Additionally, the contribution of treated wastewater from the treatment plant currently permitted by the City’s NPDES permit will continue to meet the requirements set forth by the permit.

Providing educational information to the public on the TMDL program, DEQ requirements and the City’s involvement is a priority to ensure our community is well-informed. DEQ’s Be Septic Smart tri-fold informational pamphlet is available within City Hall’s Public Works office, and TMDL information, DEQ website links, and the City’s implementation plan are also accessible to the public via the City’s website. Updates to the website will be made as they become available throughout the TMDL implementation process.
