Submitted by Puget Sound Clean Air Agency.
The Puget Sound Clean Air Agency (Agency) is providing public notice for a proposed permit and public hearing for Darling Ingredients Inc. to replace rendering equipment, including a meat cooker, that had been previously destroyed in a fire. The rendering facility will consist of raw material delivery trucks, raw material receiving pits, meat cooker, processing equipment such as screens and screw presses. The processes will all be totally enclosed in a building under negative pressure with generated emissions routed to control devices including a condenser, a venturi scrubber, and thermal oxidizer. Facility-wide emissions are 0.63 tons per year (tpy) nitrogen oxides, 3.06 tpy sulfur oxides, 5.01 tpy of particulate matter (10 microns or less), 1.25 tpy of carbon monoxide, 4.91 tpy of volatile organic compounds, and 4,415 pounds per year of hydrogen sulfide. This project does not include an increase in material processing rate over previously permitted levels.
The Agency’s proposed Order of Approval (Order) contains numerous new conditions that aim to assure compliance with the applicable regulations. The proposed Order includes a requirement for the facility to establish a complaint response program, including a public complaint phone line. The proposed Order requires periodic inspections for compromises in the integrity of the cooking system and its associated ductwork or in the building envelope, and unrepaired compromises may constitute violations of the Order. Additionally, the proposed Order requires periodic testing for emissions of volatile organic compounds, carbon monoxide, nitrogen oxides, particulate matter, sulfur oxides, and hydrogen sulfide.
