Permit to Operate (PTO)

A Permit to Operate (PTO) is a regulatory requirement issued by the Department of Environment and Natural Resources – Environmental Management Bureau (DENR-EMB) for facilities that operate air pollution-emitting equipment or sources. It ensures compliance with the Clean Air Act of 1999 (RA 8749) and DENR regulations.

As an experienced environmental consultant in the Philippines, we help businesses secure PTOs quickly while complying with all DENR technical and legal requirements.

• Your facility’s air pollution sources meet emission standards
