This report documents the process that the National Park Services and two consultants used at Yellowstone National Park to introduce environmentally preferable cleaning products. Grand Teton National Park implemented a similar program started in April 1999. This case study is intended to help other Federal agencies and private businesses understand how to carry out a 'green' cleaning project. This report identifies the elements crucial to the project's success and discusses next steps to assure that the project is institutionalized. Five appendices contain supplemental material. Appendix A presents reasons why Federal facilities and others should consider environmentally preferable cleaning products. Appendix B contains an ingredient guide and glossary identifying chemicals found in commonly used commercial and consumer cleaning products. Appendix C presents information to consider when reviewing Material Safety Data Sheets (MSDSs) and labels for health and environmental effects of cleaning products. Suggestions are given on evaluating products and setting goals for an environmentally preferable cleaning project. Appendix D contains a description of the environmentally preferable products used by Yellowstone and Grand Teton National Parks. Appendix E contains a copy of the City of Santa Monica, California's 1998 Custodial Product Bid Specifications. The Santa Monica bid specifications can be a good starting point for evaluating cleaning products.
