Friends of Toppenish Creek


FOTC engages policy makers, regulators, and the public on a number of environmental issues:


Manure Spraying: We advocate for a ban on spraying manure into the air during episodes of poor air quality. Some of our communications are provided below:

Riverview Dairy: Neighbors have complained about pollution from this dairy for decades. FOTC pushes agencies to enforce laws against pollution from this facility, as shown below:

Tech Note 23: WA Ecology and WSDA told the public in 2015 that they would survey all WA manure lagoons using this document and use that survey to assess the status of the lagoons. The agencies have failed to do so as shown below:

WSDA Dairy Nutrient Management Program (DNMP): In 2003 the legislature handed to WSDA the authority to conduct investigations of manure discharges on WA dairies. WSDA has done an inadequate job as shown below:

Environmental Risk Tracking System (ERTS): FOTC shows that enforcement of the ERTS with respect to WA dairies is weak and protects dairies more than the environment. Below ar four legitimate ERTS complants from the FOTC that Ecology and WSDA have so far ignored.

Water Testing in the Lower Yakima Valley (LYV): FOTC attempts to engage Ecology regarding adherance to the scientific process when studying water quality in the LYV. FOTC believes the current process is flawed because the Environmental Information Monitoring (EIM) data base does not gather data from the LYV "Dairy Cluster", and because Ecology does not test for nitrates and nitrites separately.

YRCAA Oversight: FOTC asked WA Ecology to exercise their legally authorized oversight of the Yakima Regional Clean Air Agency, as shown in the correspondence below. So far Ecology has declined to do so.

Dissolve YRCAA: FOTC provides reasons why the Yakima County Commissioners should dissolve the Yakima Regional Clean Air Agency. See documentation below:

Yakima Basin Water Study

In 2019 Friends of Toppenish Creek completed a study of water quality in the Yakima Basin. Surprisingly this study showed elevated levels of dioxins and furans in Lower Yakima Valley domestic wells. FOTC shared the data with the WA State Dept. of Ecology and that agency is completing follow up studies. To read the study report click HERE


As a Public Service, to assist the work of the Lower Yakima Valley Groundwater Management Area, Friends of Toppenish Creek will post relevant material for the GWMA Regulatory Work Group on this page.
