The U.S. Department of Commerce has agreed separately with the European Commission and the Federal Data Protection and Information Commissioner of Switzerland upon similar sets of data protection principles ("Safe Harbor Privacy Principles") and frequently asked questions (the “U.S.-EU Safe Harbor Framework” and the “U.S.-Swiss Safe Harbor Framework”) to enable U.S. companies to satisfy the requirement under the Data Privacy Laws that adequate protection be given to personal information transferred from the EU or Switzerland to the United States. Consistent with its commitment to protect personal privacy, Nalco adheres to the respective Safe Harbor Privacy Principles with respect to all Personal Data received from employees, customers, vendors, commercial visitors, and other business parties by Nalco in the United States from the European Economic Area and from Switzerland, in any format including electronic, paper or verbal. Within the scope of the preceding, Nalco intends to cover email communications, and the offline collection of customer data such as details relating to sales calls, sales notes, and service reports. In addition Personal Data is handled in accordance with the descriptions of the handling of Personal Data in this Privacy Policy.

More information about Safe Harbor program can be found at the U.S. Department website Individuals in the EU and Switzerland may contact the Nalco Safe Harbor Privacy Contact identified below to review the Personal Data that Nalco holds about them. If an individual in the EU or Switzerland cannot resolve an issue concerning his/her Personal Data, such individual can contact the local data protection authority for assistance.
