Definition of Poisonous and Toxic Fumes
- Section 5t of RA 8749 defines poisonous and toxic fumes as emissions exceeding internationally accepted standards including WHO guideline values.
Supreme Court Clarification on Incineration Ban
- The Supreme Court decision in Metro Manila Development Authority (MMDA) vs. Jancom Environmental Corporation clarified that Section 20 does not absolutely ban incineration.
- Only burning processes that emit poisonous and toxic fumes are prohibited.
Conditions for Permitted Thermal Treatment Technologies
- Thermal treatment technologies, whether burn or non-burn (as defined in DENR Administrative Order 2000-81), may be operated if they meet emission standards for stationary sources under Section 19 of RA 8749.
- Compliance with all relevant provisions of RA 8749 and other applicable Philippine laws is mandatory.
Interim Coverage and Monitoring Limitations
- Due to limited capabilities for monitoring emissions from municipal solid waste incineration, the current circular focuses on incineration of toxic, hazardous, medical, and bio-medical wastes.
- Toxic and hazardous wastes are defined under RA 6969.
- Medical and bio-medical wastes are defined under RA 8749 and its implementing rules (DENR Administrative Order No. 2000-81).
Requirements for Incineration Facilities
- Incineration of toxic, hazardous, medical, and bio-medical wastes is permitted only in state-of-the-art facilities.
- Facilities must demonstrate minimal air pollutant emissions compliant with the standards in RA 8749 and its implementing rules.
Role of the Environmental Management Bureau (EMB)
- The EMB is tasked with issuing technical and procedural guidelines to facilitate the implementation of the circular.
Adoption and Authority
- The Memorandum Circular was adopted on July 12, 2002, by Secretary Heherson T. Alvarez.
