Department of <br />Toxic Substances <br />Control <br />Our Mission is <br />to provide the <br />highest level of <br />safety, and to <br />protect public <br />heafth and the <br />environment <br />.from toxic <br />harm. <br />State of California <br />111 California <br />Environmental <br />Protection Agency <br />Fact Sheet, December 2008 <br />Requirements for Generators of <br />Treated Wood Waste (TWW) <br />What is Treated Wood Waste (TWW)? <br />TWW is wood commonly used in ground or water contact applications that has been <br />removed from service. This wood is typically treated with preserving chemicals that <br />protect the wood from insect attack and fungal decay during its use. Examples <br />include fence posts, sill plates, landscape timbers, pilings, guardrails, and decking. <br />What are the Health and Environmental Hazards? <br />TWW contains hazardous chemicals that pose a risk to human health and the <br />environment. Arsenic, chromium, copper, creosote, and pentachlorophenol are among <br />the chemicals added to preserve wood. These chemicals are known to be toxic or <br />carcinogenic. Harmful exposure to these chemicals may result from dermal contact with <br />TWW, or from inhalation or ingestion of TWW particulate (e.g., sawdust and smoke). <br />What are the Hazardous Waste/Alternative Management Standards <br />(AMS)? <br />Because TWW contains hazardous chemicals, at elevated levels, it is subject to <br />California's Hazardous Waste Control Law. The Department of Toxic Substances <br />Control (DTSC) has developed alternative management standards (AMS) for TWW that <br />are based upon full hazardous waste requirements but are adjusted for the unique <br />circumstances associated with TWW. The AMS is in California Code Regulations (Cal. <br />Code Regs.) title 22, division 4.5, chapter 34. In summary, AMS lessen storage <br />requirements, extend accumulation periods, allow shipments without a hazardous waste <br />manifest and a hazardous waste hauler, and allow disposal at specific non-hazardous <br />waste landfills. The AMS simplify and facilitate the safe and economical disposal of <br />TWW. (Note -TWW that is removed from utility services or is a RCRA hazardous <br />waste is not eligible for AMS.) <br />What are the Handling and Disposal Requirements for Tvvvv? <br />The AMS, which went into effect on July 1, 2007, are intended to ease regulatory <br />burdens. Although hazardous waste generators are required to properly classify their <br />waste through knowledge or laboratory analysis, generators of TWW can presume their <br />TWW is hazardous waste and avoid expensive laboratory testing. Generators can then <br />manage their waste in accordance with the AMS, including disposal at certain non- <br />hazardous waste landfills. Upon acceptance at these certain landfills, the TWW, at that <br />point, becomes non-hazardous waste pursuant to Health and Safety Code section <br />25150.8. Specific generator requirements for households, small business, and all others <br />are presented in the following sections:
