A Guide to the DENR Permit to Operate (PTO)

The Philippine Clean Air Act (RA 8749) mandates that all sources of air pollution must be regulated. A primary tool for this regulation is the Permit to Operate (PTO), issued by the DENR-EMB. This permit is required for any facility that has equipment like generator sets, boilers, or manufacturing machinery that releases pollutants into the atmosphere.

The Purpose of a PTO

A PTO ensures that a facility's emissions are within the national air quality standards. It certifies that the pollution source equipment and any installed control devices are operating correctly and efficiently. Without a valid PTO, a facility can face severe penalties, including fines and closure orders.

Key Application Steps

The application process generally involves:

• An 'Engineer's Report' detailing the equipment, processes, and pollution control measures.
• An emission test conducted by a DENR-accredited third-party laboratory.
• Submission of the application to the relevant DENR-EMB regional office.
• Potential site inspection by DENR personnel.

Securing a PTO can be a complex technical process. Engaging with a qualified consultant can help streamline the application, ensure accurate emissions testing, and facilitate a smoother path to compliance.
