Revised Priority Chemical List Regulations

The PCL enumerates specific hazardous chemicals by their Chemical Abstract Service (CAS) numbers, Philippine Inventory of Chemicals and Chemical Substances (PICCS) names, and chemical names.
It includes a wide range of chemicals such as chlorinated benzenes, heavy metal compounds (arsenic, cadmium, mercury, lead), solvents (benzene, chloroform, methylene chloride), pesticides (mirex), and other toxic substances.
Certain chemicals like asbestos, cyanide, and mercury compounds are now regulated under separate Chemical Control Orders (CCO).
Some chemicals identified as ozone-depleting substances (e.g., trichloroethane, chlorofluorocarbons, halons) are also regulated under specific CCOs.

Mandatory annual submission of reports to the DENR-Environmental Management Bureau (EMB-Central Office) by January 31 each year.
Requirement to file a Hazardous Wastes Registration Form with the appropriate EMB Regional Office.
Registration and reporting must be done using forms prescribed by the Department and be accompanied by the payment of prescribed fees.

Non-registration under the provisions of DAO 29, Title II related to the PCL incurs an administrative fine of PHP 50,000.
Failure to submit the required annual report results in a PHP 10,000 fine.
Non-compliance with permit or clearance conditions is subject to graduated fines based on the number of violated conditions:
- PHP 10,000 for one or two conditions.
- PHP 20,000 for three or four conditions.
- PHP 30,000 for more than four conditions.
- PHP 40,000 for extensive non-compliance, including other DENR environmental requirements.

The Department of Environment and Natural Resources (DENR) may adopt incentives for compliant sectors as per existing rules and regulations.
The Order took effect fifteen (15) days after publication in two newspapers of general circulation and after submission to the National Administrative Register.

Emphasizes regulation of toxic and hazardous substances to protect environmental and public health.
Ensures traceability and accountability of chemical use through mandatory registration and reporting.
Promotes compliance through a system of administrative fines and potential incentives.
Aligns with broader environmental laws regulating hazardous substances and ozone-depleting chemicals to fulfill international and national obligations.
