What is a Permit to Operate?

A Permit to Operate is issued by DENR-EMB under the Philippine Clean Air Act (RA 8749) and authorizes the operation of air pollution source installations such as generator sets, boilers, and furnaces.

Who needs a Wastewater Discharge Permit?

Establishments that discharge wastewater into bodies of water or land are required to secure a Discharge Permit under the Philippine Clean Water Act (RA 9275) and its implementing rules.

Does my establishment need a Pollution Control Officer?

Establishments whose operations are actual or potential sources of air, water, or land pollution are required to designate and seek accreditation for a Pollution Control Officer under DAO 2014-02, as amended by DAO 2018-07.

Is an ECC the only environmental permit a facility needs?

No. The ECC covers the project under the Philippine EIS System. Operating facilities typically also require air, water, and hazardous waste permits or registrations, depending on their equipment and waste streams.

What happens if a facility operates without the required permits?

Operating without required permits can result in notices of violation, fines, and cease and desist orders under the applicable laws. Penalties vary by statute and violation.

Which DENR Permits Does a Facility Need?

Most establishments in the Philippines hold several environmental permits at once. The ECC or CNC covers the project itself. Separate permits then regulate air emissions under the Philippine Clean Air Act (RA 8749), wastewater discharges under the Philippine Clean Water Act (RA 9275), and hazardous waste under RA 6969. Most establishments must also designate an accredited Pollution Control Officer.

Air and water permit applications are generally processed through the EMB Online Permitting and Monitoring System. Facilities within the Laguna de Bay Region are additionally subject to the permitting requirements of the Laguna Lake Development Authority (LLDA).

EnviSynergy maps every permit a facility needs, prepares the technical requirements, and tracks validity periods so that renewals are filed on time.
