Complaints of odor wafting through Ripon from the new Diamond Pet Food Plant on South Stockton Avenue has the firm taking steps to abate the odors that are noticed when south winds cause the angst of residents.

Diamond staffers have provided the Ripon City Council with a list of actions taken to confront the problem and their search for answers.

They have worked with source testers to develop protocol for the required testing of the wet cyclone exhaust at the plant as well as reviewing the county pollution control district’s complaint history.

They have also reviewed the cold plasma cost proposal and pilot scale testing proposal and recently scheduled a site visit with a cold plasma vendor to discuss a pilot scale test in light of the facility’s operation and equipment configuration.

Diamond officials have also reviewed the previous source tests conducted at the milling and grinding operation to properly address their PM 10 emissions in the permit application.  They are currently arranging source testing of the wet cyclone as part of the permit application and continuing to gather information assessing the cold plasma process and issues related to use at the Ripon plant.
