Environmental Laws
Section 19. Pollution From Stationary Sources. - The Department shall, within two (2) years from the effectivity of this Act, and every two (2) years thereafter, review, or as the need therefor arises, revise and publish emission standards, to further improve the emission standards for stationary sources of air pollution. Such emission standards shall be based on mass rate of emission for all stationary sources of air pollution based on internationally-accepted standards, but not be limited to, nor be less stringent than such standards and with the standards set forth in this Section The standards, whichever is applicable, shall be the limit on the acceptable level of pollutants emitted from a stationary source for the protection of the public's health and welfare.
With respect to any trade, industry, process and fuel-burning equipment or industrial plant emitting air pollutants, the concentration at the point of emission shall not exceed the following limits: Pollutants Standard Applicable to Source Maximum Permissible Limits (mg/Ncm) Method of Analysis a 1.

Phosphorus Fentoxide Any source 200 as P2O5 Spectrophotoimetry 13. Zinc and its compounds Any source 100 as Zn AAS b a Other equivalent methods approved by the Department may be used.
" Atomic Absorption Spectrophometry c All new geothermal power plants starting construction by 01 January 1995 shall control HsS emissions to not more than 150g/GMW-Hr " All existing geothermal power plants shall control HsS emissions to not more than 200g/GMW-Hr. within 5 years from the date of efectivity of these revised regulations.
e Best practicable control technology for air emissions and liquid discharges. Compliance with air and water quality standards is required.
1 Emission limit of Nickel Carbonyl shall not exceed 0.5 mg/Ncm. Provisional Guideline Provided, That the maximum limits in mg/Ncm particulates in said sources shall be: 1. Fuel burning Equipment (a) Urban or Industrial Area 150 mg/Ncm (b) Other Area 200 mg/Ncm 2. Cement Plants (Kilns, etc.) 150 mg/Ncm 3. Smelting Furnaces 150 mg/Ncm 4. Other Stationary Sources a 200 mg/Ncm a Other Stationary Sources means a trade, process, industrial plant, or fuel burning equipment other than thermal power plants, industrial boilers, cement plants, incinerators and smelting furnaces Provided, further, That the maximum limits for sulfur oxides in said sources shall be: (1) Existing Sources (i) Manufacture of Sulfuric Acid and Sulf(on)ation Process 2.0 gm. Ncm as SO3 (ii) Fuel Burning Equipment 1.5 gm. Ncm as SO2 (iii) Other Stationary Sources a 1.0 gm. Ncm as SO3 (2) New Sources (i) Manufacture of Sulfuric Acid and Sulf(on)ation Process 1.5 gm. Ncm as SO3 (ii) Fuel Burning Equipment 0.7 gm. Ncm as SO2 (iii) Other Stationary Sources a 0.2 gm. Ncm as SO3 a Other Stationary Sources refer to existing and new stationary sources other than those caused by the manufacture of sulfuric acid and sulfonation process, fuel burning equipment and incineration.
For stationary sources of pollution not specifically included in the immediately preceding paragraph, the following emission standards shall not be exceeded in the exhaust gas: I. Daily And Half Hourly Average Values Daily Average Values Half Hourly Average Values Total dust 10 mg/m3 30 mg/m3 Gaseous and vaporous organic substances, expressed as total organic carbon 10 mg/m3 20 mg/m3 Hydrogen chloride (HCl) 10 mg/m3 60 mg/m3 Hydrogen fluoride (HF) 1 mg/m3 4 mg/m3 Sulphur dioxide (SO2) 50 mg/m3 200 mg/m3 Nitrogen monoxide (NO) and nitrogen dioxide (NO2), expressed as nitrogen dioxide for incineration plants with a capacity exceeding 3 tonnes per hour 200 mg/m3 400 mg/m3 Nitrogen monoxide (NO) and nitrogen dioxide (NO2), expressed as nitrogen dioxide for incineration plants with a capacity of 3 tonnes per hour or less 300 mg/m3 Ammonia 10 mg/m3 20 mg/m3 II. All Average Values over the Sample Period of a Minimum of 4 and Maximum of 8 Hours Cadmium and its compounds, expressed as cadmium (Cd) total 0.05 mg/m Thallium and its compounds, expressed as thallium (Tl) Mercury and its compounds, expressed as mercury (Hg) 0.05 mg/m3 Antimony and its compounds, expressed as antimony (Sb) total 0.5 mg/m3 Arsenic and its compounds, expressed as arsenic (As) Lead and its compounds, expressed as lead (Pb) Chromium and its compounds, expressed as chromium (Cr) Cobalt and its compounds, expressed as cobalt (Co) Copper and its compounds, expressed as copper (Cu) Manganese and its compounds, expressed as manganese (Mn) Nickel and its compounds, expressed as nickel (Ni) Vanadium and its compounds, expressed as vanadium (V) Tin and its compounds, expressed as tin (Sn) These average values cover also gaseous and the vapor forms of the relevant heavy metal emission as well as their compounds: Provided, That the emission of dioxins and furans into the air shall be reduced by the most progressive techniques: Provided further, That all average values of dioxin and furans measured over the sample period of a minimum of 6 hours and a maximum of 8 hours must not exceed the limit value of 0.1 nanogram/m3.
Pursuant to Section 8 of this Act, the Department shall prepare a detailed action plan setting the emission standards or standards of performance for any stationary source, the procedure for testing emissions for each type of pollutant, and the procedure for enforcement of said standards.
Existing industries, which are proven to exceed emission rates established by the Department, in consultation with stakeholders, after a thorough, credible and transparent measurement process shall be allowed a grace period of eighteen (18) months for the establishment of an environmental management system and the installation of an appropriate air pollution control device: Provided, That an extension of not more than twelve (12) months may be allowed by the Department on meritorious grounds.
