In a jubilant installation ceremony last 20 August 2019, Engr. Efren B. Carido now heads the Mines and Geosciences Bureau Regional Office No. X workforce with no less than Director Wilfredo G. Moncano installing him as OIC, Regional Director pursuant to DENR Special Order No. 2019-556 dated August 8, 2019 and signed by Secretary Roy A. Cimatu. Witnessed by MGB-X personnel and some DENR-X officials, RD Carido received the banner handed to him by Engr. Daniel S. Belderol symbolizing the turn-over of responsibilities as the new head of MGB-X.

In his acceptance speech, RD Carido said that he positively feels at home with MGB-X. Further on his speech, he clearly laid down concrete directions to where he wants to steer MGB-X to. He has clear directions and plans for each division such as the need to capacitate the LGUs in the processing of locally issued permits like CSAG. He wants MSESDD to create linkage with the academe in its efforts to intensify IEC campaign and help change the negative views on mining. He also highlights the need to continue to create a healthy link with other law enforcement agencies and capacitate local enforcers in carrying out the mandates of the office. He also envisioned to come up with an operational system that would answer the requirements of the newly enacted RA 11032 otherwise known as the Ease of Doing Business and Efficient Government Delivery Service Act of 2018.
Capping the ceremony are marching orders of Director Wilfredo G. Moncano with highlight on the intense No Corruption order of the President. He warned all present that any acts of that nature will be dealt with severely. He enjoined all not to use the office as a clear venue of any form of corruption as it will not go unpunished.
