Dangerous Waste Designation Tool
This designation tool will help your business determine regulated dangerous waste from regular trash.

U.S. Environmental Protection Agency (EPA) Clean Water Act Analytical Methods
Industries and municipalities use these laboratory analytical methods to analyze the chemical, physical, and biological components of wastewater and other environmental samples, required by regulations under the authority of the Clean Water Act (CWA). This site offers information on alternate test procedures, method flexibility, and other special topics.

EPA Clean Water Act Analytical Methods Alternate Test Procedures
EPA's Office of Science and Technology manages the program for CWA methods used by industries and municipalities to analyze the chemical, physical, and biological components of wastewater and other environmental samples as required by regulations. Analytical methods published in the Code of Federal Regulations (CFR) at Title 40 Part 136 may have alternate test procedures and/or method flexibility. This webpage provides guidance to allow labs to evaluate methods that could be adapted to micro-chemistry scale that reduce generated waste.

EPA Environmental Management Guide for Small Laboratories
This document assists those responsible for administering or improving environmental management programs at small labs. The document outlines management and federal regulatory issues for improving lab environmental performance, but does not prescribe in detail all required factors and considerations.

EPA Forum on Environmental Measurements (FEM)
FEM is a standing committee of senior EPA managers established to develop policies to guide EPA’s measurement community in:
  • validating and disseminating methods for sample collection and analysis.
  • ensuring that monitoring studies are scientifically rigorous, statistically sound, and yield representative measurements.
  • employing a quality-systems approach that ensures the data gathered and used by EPA is of known and documented quality.

FEM may be a source of modified standard methods that reduce the use of hazardous substances or the generation of hazardous waste.

EPA Safe Chemical Management in Schools
More than 53 million children and about 6 million adults spend a significant portion of their days in more than 120,000 public and private school buildings. Many of these buildings are old and in poor condition, and may contain environmental conditions that inhibit learning and pose increased risks to the health of children and staff.

Industrial Materials Exchange (IMEX)
IMEX is one of the premiere material exchanges in the Pacific Northwest. IMEX is a free service designed to help your business find markets for your industrial by-products, surplus materials, and reusable wastes. Businesses, offices, schools, and individuals "advertise" their surplus/unwanted materials, or materials they are seeking, by submitting an electronic IMEX listing form. They are then listed on the IMEX web site, to be viewed by interested waste generators and waste recyclers.

King County Laboratory Waste Management Guide
This report was prepared by the Local Hazardous Waste Management Program in King County, Washington. The program seeks to reduce hazardous waste from households and small quantity generator businesses in King County by providing information and technical assistance to protect human health and the environment.

Department of Ecology Accreditation of Environmental Laboratories
Ecology’s Laboratory Accreditation Unit oversees all accredited labs in Washington. They are familiar with all labs that have been accredited for modified standard methods and may help identify available alternative methods. Their publication titled Procedure Manual for the Environmental Laboratory Accreditation Program, includes guidance on the proficiency testing required before a lab can apply for accreditation for a modified method. The Accreditation Unit can also identify which methods ????

 Department of Ecology: Accredited Laboratory Search
Some analytical laboratories in Washington have modified certain regulatory analytical methods and have earned accreditation for the modified method. Analytical labs may consider connecting with similar labs to inquire about modified analytical methods that use less hazardous substance or generate less hazardous waste.
