Study Notes
Dust Control
- Use of water, chemicals, and containment methods are required to avoid dust during demolition.
- Asphalt, oil, water, or approved chemicals should be used to suppress dust from roads and material stockpiles.
- Hoods, fans, and fabric filters are required to contain dust during material handling, particularly with operations like sandblasting.
- Open loaded trucks transporting dusty materials need to be covered to prevent dust release.
Volatile Organic Compound Emissions
- Storage tanks for volatile organic compounds (VOC) exceeding 150,000 liters must be pressurized to prevent vapor loss.
- Waste gases from ethylene sources must be properly burned or disposed of using approved methods, except for emergency relief and vapor blowdown systems.
- Organic solvent emissions are limited to 1.5 kg/hour and 7.0 kg/day unless appropriate ventilation and control systems are in place.
Other Prohibited Acts
- Nuisance: Emission of air contaminants causing a nuisance as defined in the Civil Code of the Philippines is prohibited.
- Open Burning: Open fire is prohibited except in specific cases, such as food cooking, recreation, fire hazard abatement, disease and pest control, disposal of dangerous materials, fire training, and agricultural, forest, and wildlife management practices.
- General Restrictions:
- Plants and sources cannot operate beyond the limits of their control devices or exceed specified air emission standards.
- Building or operating new sources or modifications that exceed ambient air quality standards is prohibited.
- Concealing air pollutant emissions is forbidden.
- Using devices or methods that conceal or dilute emissions without reducing the total amount emitted is prohibited.
Source Monitoring, Record Keeping, and Testing
- The Department of Environment and Natural Resources (DENR) can require source owners to install, maintain, and monitor equipment, sample emissions and ambient air pollutants, keep records, and report periodically.
Terminologies
- Air pollutant: Any matter in the atmosphere other than oxygen, nitrogen, water vapor, carbon dioxide, and inert gases that harms health or the environment.
- Air pollution: Alteration of the atmosphere's physical, chemical, or biological properties due to discharges of substances.
- Ambient air quality guideline values: Concentrations of air pollutants over specified periods, serving as goals for health and public welfare protection.
- Ambient air quality: Overall pollution level in a broad area, reflecting the atmosphere's average purity.
- Certificate of Conformity: DENR certification for new vehicles, confirming they meet requirements.
- Greenhouse gases: Gases potentially causing global warming, including carbon dioxide, methane, oxides of nitrogen, chlorofluorocarbons, etc.
- Octane Rating or Anti-Knock Index (AKI): Rating of gasoline's anti-knock characteristic, calculated from Research Octane Number (RON) and Motor Octane Number (MON).
- Ozone Depleting Substances (ODS): Substances depleting the ozone layer, including chlorofluorocarbons, halons, etc.
- ** Persistent Organic Pollutants (POPs)**: Organic compounds persistent in the environment, bioaccumulating and harming health and the environment, including dioxin, furan, PCBs, organochlorine pesticides, etc.
- Standard of performance: Emission limit achieved using the best emission reduction system, considering costs.
- Stationary source: Any building or immobile structure emitting air pollutants.
RA 8749: Philippine Clean Air Act of 1999
- Policies: Implement a national air pollution management program, encourage self-regulation and market-based measures for pollution prevention, focus on pollution prevention, promote public awareness and participation, enforce accountability for environmental impacts, provide funding for cleanup and compensation.
- Air Quality Management System: Establishes an air quality monitoring and information network.
- Gross violation: Defined by three or more offenses, blatant disregard of orders, or irreparable damage to the environment.
- Penalties: Offenders face imprisonment of 6-10 years. Juridical persons face penalties for their representatives.
Montreal Protocol
- An international treaty focused on protecting the ozone layer by phasing out production of ozone-depleting substances.
- Opened in 1987 and ratified by 191 countries.
- Focuses on phasing out HCFCs by 2030.
- Initially targeted CFCs and chlorinated hydrocarbons, reducing their use.
- HCFCs and HFCs (powerful greenhouse gases) are also addressed, with a gradual phasing-out plan for HCFCs.
- While transitioning to HFCs does not immediately worsen global warming, continued increased use of HFCs over time could exacerbate climate change.
- Ozone depletion was first discussed by the UNEP in 1976, and the Vienna Convention for the Protection of the Ozone Layer was adopted in 1985.
