Document Description
A temporary emergency Hazardous Waste Permit has been granted to Northrop Grumman Space Technology (NGST) to store hazardous waste for up to 90 days and then to treat the hazardous waste by dilution in order to transport it offsite for disposal. The hazardous waste to be stored and treated is approximately 2 gallons of a reactive mixture, consisting of 20% hydroxyethylhydrazinium nitrate (HEHN), 70% water, and 10% organic solvents. The hazardous waste was generated from research activities. The waste was inaccurately classified as a flammable liquid rather than an explosive hazard, delaying shipment of the waste to a disposal site. The 90-day limit for storage of a hazardous waste allowed under a previous emergency permit will expire before permission is secured from Department of Transportation to ship the hazardous waste. Before shipment, the mixture will be treated by further dilution with water from approximately 20% HEHN to 1% to 2% HEHN. The final volume of hazardous waste will be approximately 40 gallons. As NGST does not hold a facility hazardous waste management permit for the location where the storage and treatment would take place, the Department of Toxic Substances Control (DTSC) has determined that an emergency permit should be issued. The permit is effective from November 13, 2008 to February 10, 2009.
