Responding to amendments to the Toxic Chemical Substances Control Act（TCSCA）proposed by the EPA to further strengthen schemes of source control, this project proposed workflows, information requirements, operation models, and guidances of chemical source control and registration, based on the spirit of internal chemical source control and management. Relevant supporting IT tools and platforms were established. Followed by the official enforcement of the TCSCA, this project provided assistance in drafting management provisions governing registration and related compliance measures that prepared a firm ground for future chemical source control registration and facilitate communication with stakeholders. According to the schedule planned, this project the punctually proposed sub-ordinance content authorized by the amendment of the TCSCA. This covered the regulations of registration management and relevant appendixes. A preliminary frame of new chemical registration guidance was provided, including process of registration, information requirement by quantity bands, criteria of exemption, and suggested testing methods. Also guidance and document relating to forms for special category registration, rules for registration serial numbers, and periodic report were suggested. To back sub-ordinance of the TCSCA, workflow of phased registration for existing chemical substances, and scheme designed for phase-2 joint registration were suggested. Also guidance and tools devised for phase 1 registration were completed. This covered program of registrants’ connection, workflow of substance prioritization, international data exchange under standard registration, as well as other compliance measures. Besides, to smooth registration process, a consolidated platform that performed all function of registration, “Chemical Substances Registration Platform” was built. The functions included new and existing chemical registration and dossier upload, online payment service, a portal page for periodic report, and a backstage for managerial evaluation. In addition, a chemical information system and tool, CHEMIST was provided for registrants to report chemical testing data and upload attachments. This project continued international information exchange, and collecting information on current and future trends of international source control management. Information on WTO SAICM development was also provided. twenty IT system operation seminars and 3 train-the-trainer workshops were delivered for industries introducing IT tools with possible aspects that they may face in system handling. Three national policy promotion conferences were held to ensure stakeholders understanding of chemical hazards control and registration development. Meanwhile opinions and views of stakeholders were taken into account the improvement process of registration framework and supporting system tools. Analysis based on opinions and questions collected was provided as a feedback to industry, which helped implement regulation and foster responsible business practices. It is recommended to update all technical guidances and supporting installation developed in this project to comply with the official version of registration regulations for proper implementation.
