What is Household Hazardous Waste?
The US Environmental Protection Agency states that Americans generate 1.6 million tons of household hazardous waste (HHW) every year, and the average home has accumulated as much as 100 pounds of HHW. This represents a risk to the household and to the environment if the HHW is improperly stored or disposed.
Household hazardous waste consists of the unwanted or unusable portion of consumer products that contain substances that can harm human health or the environment. Hazardous products are often found in the categories of automotive and home improvement products, cleaners, and pesticides. A product is hazardous if it exhibits one or more of the following properties in the table below.
Can be easily ignited by spark, flame or heat. Flammables have a flash point of less than 100oF, while ignitables have a flash point of less than 140oF.
Can explode or react violently when subjected to heat, sudden shock, pressure or contact with an incompatible substance.
Can burn and destroy living tissues and dissolve metals. A corrosive substance has a pH value of less than or equal to 2.0, or greater than 12.5.
Can cause injury or death through ingestion, inhalation, or skin absorption. Many products that are flammable, corrosive or reactive are also toxic.

Hazardous wastes from households are not regulated in the same way as hazardous wastes from industry, businesses, and farms simply because it would be impossible to enforce this ubiquitous and pervasive waste stream. In fact, household hazardous wastes are specifically exempted under the federal law regulating hazardous waste disposal, the Resource Conservation and Recovery Act (RCRA). Even so, the accumulated environmental impact from household hazardous wastes poses a significant and manageable risk.

18.6% Batteries 17% Oil
12.1% Cosmetics 11% Batteries
11.5% Cleaners 4.5% Gas Cylinders

4.1 % Yard Items (pesticides, fertilizers) 3.4% Hobby/Other(pool, art supplies)
What HHW Is Not: Conditionally Exempt Generators (CESQG)
Small businesses can find themselves in a special predicament if they purchase and use hazardous materials. While households are excluded from RCRA regulation, businesses are not - even if they are using the same types of materials used by households.
Non-residential generators of small amounts of hazardous waste are known as "conditionally exempt small quantity generators" (CESQGs). CESQGs are those that generate less than 220 pounds of hazardous waste in a month or have an accumulation of less than 2,200 pounds of hazardous waste. As with household hazardous wastes, RCRA does not regulate these businesses the same as large industrial hazardous waste generators because federal enforcement would be very difficult or impossible. Instead, the CESQGs are required to manage their wastes at a RCRA permitted facility (a landfill, resource recovery, or hazardous waste facility).
CESQG wastes can represent a large portion of the hazardous wastes entering municipal wastes streams. A Washington State study estimated that the average small business generates 1,400 pounds of hazardous waste per year (119 pounds per month). As with HHW, these wastes pose hazards to human health and the environment. In response, many states or local governments adopt stricter rules that regulate CESQGs or ban their wastes from landfills. This leaves some businesses in the dilemma of having to store wastes, or pay large fees for disposing of small amounts of hazardous wastes, if special collection systems are not available. The recognition of this problem has prompted some communities to establish programs in which businesses can bring hazardous wastes, for a small fee, to the household hazardous waste collection facility. In these cases, the facilities must operate under a RCRA permit.
