Waste Incinerator Air Pollutant Emissions Standards

Waste Incinerator Air Pollutant Emissions Standards Original 14 articles promulgated by Environmental Protection Administration order on November 30, 1992; revisions to Article 3 promulgated on August 6, 1997; revisions to Articles 1, 11, and 13 promulgated on April 7, 1999 Revisions to Article 8, Tables 1 and 2, Article 10, the deletion of Article 9, and the addition of Artilce 12-1 promulgated on December 25, 2006. Article 1 These Standards are determined pursuant to Article 20, Paragraph 2 of the Air Pollution Control Act. Article 2 Terms and Symbols used in these Standards are defined as follows “mg” means 1 milligram, equal to 0.001 grams.I. “Nm 3 ” means a cubic meter at a temperature of 273 K and a pressure of 1 atmosphere.II. “ppm” means parts per million.III. “C” means pollutant concentration corrected to Standard Oxygen Basis, measured in ng-TEQ/Nm 3 ppm or mg/Nm 3 . IV. “Q” means emission quantity corrected to Basic Oxygen Standard, measured in Nm 3 /min.V. “Cs” means the measured pollutant concentration based on test method, not corrected to Standard Oxygen Basis, measured in ng-TEQ/Nm 3 ppm or mg/Nm 3 . VI. “Os” means the actual measured oxygen concentration in emissions.VII. “E” means the actual oxygen concentration of oxygen-enriched gases imported into incinerator.VIII. “Variable one-hour average” means the average of continuously fluctuating values during a single hour. IX. Article 3 For matters not provided in these Standards, the regulations of other relevant standards shall apply; however, Waste Incinerator Dioxin Control and Emission Standards shall be determined separately. Article 4 These Standards shall apply to stack emissions from general waste and industrial waste incinerators. Article 5 Should there be particular other emission regulations for air pollutants from industrial waste incinerators such as in the Methods and Facilities Standards for the Storage, Clearance and Disposal of Industrial Waste, the more stringent regulations shall apply. Article 6 In these Standards, the definitions of “general waste” and “industrial waste” are based on relevant regulations of the Waste Disposal Act. Pollutants produced by industrial units may be controlled in accordance with the General Waste Incinerator Emission Standards if the competent authority has authorized their disposal in a general waste incinerator. Article 7 “Handling capacity”, as refrerred to in these Standards, means the maximum weight of waste fed into the said incinerator per hour (regardless of whether wet or dry). Article 8 For values determined by these Standards view Table 1 and Table 2 Article 9 (deleted) Article 10 The concentrations of all types of pollutants in stack emissions shall be calculated based on non-diluted dry emission volumes at a temperature of 273K and a pressure of 1 atmosphere. A 11% oxygen concentration shall serve as the reference standard. The correction formula is as follows: C = 21−11 21− Os ⋅ Cs When the oxygen concentration of air introduced into an oxygen-enriched combustion system exceeds 21%, an oxygen concentration of 11% shall serve as the reference standard for emissions gases. The correction formula is as follows: C = E−11 E− Os ⋅ Cs If the values in the foregoing two paragraphs (21-Os) or (E-Os) are less than 1, they shall be calculated as 1. Article 11 In these Standards, “existing incinerator” means: Construction was completed before December 2, 1992; and documentary proof thereof can be provided. I. Construction has been under way, project tender procedures were completed, or if no tenders were invited, project contracts were issued and signed before December 2, 1992. Moreover, such documentary proof was already submitted to the competent authority before March 1, 1993 in applying for verification and approval. II. Incinerators not meeting the conditions of two foregoing paragraphs shall be considered newly installed incinerators. Article 12 The local competent authority may, based on the particular needs of the local area, separately determine more stringent emission standards and submit such to the central competent authority for approval and official announcement. Article 12-1 A stationary pollution source that uses regular or industrial waste as fuel or auxiliary fuel shall use such fuel in accordance with the usage quantities permitted by the local competent authority and the regulations in Article 8, Table 2 shall apply. Article 13 Deleted Article 14 These Standards shall take effect on the date of enforcement except for articles whose enforcement date has been set separately.

When the value of Cobtained in accordance with formula C = 1364.2 Q 0.386 is greater than 220, 220 shall be the allowable emission value. 2. The carbon monoxide standard value shall be the variable one-hour average. 3. The emission standard value for all types of pollutants means the average value of sampling times that are standard in a test method unless other regulations apply. 4. If an automatic continuous test method is adopted for testing all types of pollutants the one-hour average is taken as standard value unless other regulations apply. 5. If there are multiple incinerator facilities within the premises of the same plant at the same time, then the sum of the handling capacities of each incinerator facility shall serve as a supporting basis to determine compliance with the law.

Except where other regulations apply, the emission standard value for each pollutant means the average taken during sampling as regulated in the testing method. 3. Except where other regulations apply, when employing continuous automatic testing to test for each pollutant the hourly average shall be the standard value. 4. When there is more than one set of incinerator equipment on the factory premises, the combined Handling capacity for all incinerator equipment shall be the legal standard. 5. Waste incinerators established prior to January 1, 2007, means incinerators whose construction was completed or under way, whose project tender procedures were completed, or if no tenders were invited, whose project contracts were given out and signed before January 1, 2007.
