March 19, 2021 Dear Angela Tamano, I refer to my letter of Mar 08, 2021 02:53:10 PM about your request under Executive Order No. 2 (s. 2016) on Freedom of Information in the Executive Branch, for Geotechnical Data of Angat Dam. In order for us to work further on your request, we need more information from you regarding your query. In particular, it would be helpful to know the specific geotechnical parameters you need in your study, as you are well aware that there are several geotechnical parameters measured in the course of a dam's operation. Also, we would also want to inform you that we do not have the primary data for your request since we do not measure these parameters. Nonetheless, we can help provide secondary information from the facility operators of the dam. You may use the reply function on the eFOI portal at https://www.foi.gov.ph/requests/aglzfmVmb2ktcGhyHgsSB0NvbnRlbnQiEU1XU1MtMTA0OTA0OTU4NjU4DA, for request with ticket number #MWSS-104904958658, to respond. During the period of us awaiting your reply, your request will be put on hold. If we do not receive a reply on or before Jun 11, 2021 11:03:04 AM, your request will be closed. We hope to hear from you at the soonest possible time. Thank you. Respectfully, Maricris T. Laciste FOI Officer
