Hazardous wastes are materials with hazardous properties that are no longer suitable for their original use. By law, they require special documentation, handling, storage, shipping, and treatment prior to reuse, recycling or disposal. Amounts shipped serve as a proxy for amounts generated. Yearly variations in amounts shipped are due to on-site accumulations and non-routine shipping by facilities. Amounts shown may under-report total amounts due to some direct shipping by individual facilities that were not tallied. The increase in solid waste over last year could be attributed to a greater extent of site-specific clean-ups compared to last year. Liquid waste generation remained at historical levels.
