The preparation of the written documentation may be the last activity to be completed, but not necessarily the last to be initiated. As a part of this health assessment methodology, it is recommended that each of the previous activities be documented. This information should then be integrated in the EIS in such a way that it reflects that the health impact assessment was conducted with due consideration in the overall EIA process. Thus, each of the sections of the EIS should contain succinct information pertinent to the assessment of health impacts, with more extensive material generated in connection with the health impact assessment incorporated as appendices, and with external supporting data and literature adequately referenced.
