NSSI accepts a full spectrum of hazardous and radioactive waste materials including all D, F, P, U and K hazardous waste codes and all radionuclides, including special nuclear materials. NSSI treats gases, liquids, solids, sludges, and soils. NSSI also accepts and treats recyclables, such as chlorofluorocarbons, solvents, mercury compounds, mercury contaminated substances and fluorescent tubes. NSSI provides customer site packing and labeling services and transport to the NSSI treatment facility. NSSI is available for emergency response for decontamination of chemical and nuclear material spills and for remediation services.
NSSI is currently permitted with a storage
and processing capacity of 58,530 gallons
in 20 tanks. An additional capacity of
180,793 gallons of container storage is
provided in 5 container storage areas.
NSSI provides temporary permitted
storage services for generators.
Permitting NSSI operated as an interim status Waste Treatment and Storage facility from 1980 to 1990. NSSI subsequently submitted the required Part B application and received a final Part B permit in October, 1990. Permit modifications are requested on an ongoing basis as new treatment technologies are proven and commercialized and as additional facilities are needed. NSSI is unique in that the facility permits allow storage and treatment of RCRA hazardous, mixed hazardous/radioactive and radioactive waste materials.
The NSSI waste management facility is permitted to treat wastes in portable equipment in segregated container storage areas. This allows batch processing of particular problem materials, and also facilitates research & treatment process development for waster generators and service companies. Once developed, the processes can then be commercialized and permits modified as necessary for continuous operation. NSSI has developed treatment processes for specialized Mercury wastes and for difficult hydrolysis candidates under these provisions. NSSI’s management, technical, and operations experts are available to assist generators and service companies in the development of safe, secure, cost contained solutions to hazardous waste management problems.
In 1985, as a result of public and congressional attention, radioactive/hazardous mixed waste was addresses as part of the Low-Level Radioactive Waste Policy Amendments Act (LLRWPAA) of 1985. In 1988, EPA assumed regulatory controil of mixed waste storage and treatment facility (TSDF) permitting. Thus, mixed wastes are now subject to joint control by the NRC/Agreement State and EPA. NSSI is fully permitted to accept, store, and treat all mixed wastes including special nuclear wastes. NSSI offers safety surveys, sampling, decontamination, and a full spectrum of consultation capabilities in conunction with treatment and disposal services.
NSSI transports waste materials in its own vehicles in the immediate NSSI facility area.
NSSI has arrangements with many other permitted waste transporters to transport waste to NSSI from generators outside the Houston area.
