Emergency Permit for Management of Hazardous Waste, Turn Biotechnologies, Inc., Mountain View, California

The California Department of Toxic Substances Control (DTSC), pursuant to authority granted under California Code of Regulations (CCR), Title 22, Division 4.5, Chapter 20, Sec. 66270.61, has issued an Emergency Permit to Turn Biotechnologies, Inc. (EPA ID# CAL000453368) to treat hazardous waste through a controlled reaction with a chemical solution. Specifically, one (1) 5-liter container of Diethyl Ether, one (1) 1-liter container of 1,4 Dioxane, one (1) 4-liter container of Tetrahydrofuran, one (1) 500-milliliter container of 2-Methyltetrahydrofuran, two (2) 100-gram containers of Acryloyl Chloride, one (1) 25-gram container of Hydroxylamine HCL, and one (1) 5-gram container of Dess-Martin Periodinane must be stabilized prior to transport to an authorized hazardous waste treatment, storage, and disposal facility. These chemicals are currently being stored at Turn Biotechnologies, Inc. located at 297 N. Bernardo Avenue, Mountain View, California 94043. DTSC has determined as a safety precaution to prevent an accident or severe injury, an Emergency Permit should be issued to chemically stabilize the hazardous waste prior to storage and eventual transportation off-site. Background: The containers have peroxide formation present on either the inside, outside, or the bottom of the chemicals’ containers, as well as the thread container caps. The presence of peroxide formation may be unstable at relatively low concentrations, resulting in fire and/or explosion if improperly handled. Shock-sensitive materials can decompose or detonate with external energy when dry or concentrated. If the material is improperly handled, there is a potential for a reaction, which includes fire, deflagration, or detonation. Due to the presence of peroxide formation and shocksensitive materials, DTSC considers these chemicals to be an imminent and substantial endangerment to human health and the environment. Chemical stabilization is recommended prior to transport to a permitted treatment, storage, and disposal facility. Project Activities: The treatment of these hazardous wastes involves the addition of a solution to the containers in a controlled manner to reduce the reactive or ignitable characteristics of the chemicals. Treatment will take place within a designated exclusion zone. Only technicians from Clean Harbors will be allowed in the exclusion zone. Movement, preparation, and treatment of the containers will be in accordance with established standards. Within 10 business days of the expiration of this permit, Turn Biotechnologies, Inc. will submit a final report, signed in accordance with Title 22, CCR Sec. 66270.11(d). The report shall include certification that the treatment area has been cleared of all residual hazardous waste generated from this emergency treatment and all generated waste has been properly managed. The Emergency Permit is effective beginning January 23, 2026 and shall expire on March 24, 2026.
