Optoelectronic Material and Element Manufacturing Industry Air Pollution Control and Emission Standards Article 2

Terms and symbols used in these Standards are defined as follows:I. The optoelectronic materials and components manufacturing industry (herein referred to as the “optoelectronics industry”) refers to firms engaged in the manufacture of LCD panels and related materials, elements, or products. Manufacturers of diode elements shall not be included in this category, however.II. “Volatile Organic Compounds (VOCs)” is a general designation for air pollutants containing organic compounds. However, this shall not include such compounds as methane, carbon monoxide, carbon dioxide, carbonic acid, carbides, carbonates or ammonium carbonate.III. “Permissible emissions per unit hour” refers to the annual total permissible emissions quantities of individual air pollutants from all processes of a single public or private premise recorded on the stationary pollution source operating permit for said premise converted to emissions per unit hour on the basis of the approved annual operating hours; measured in units of kg/hour.IV. “Closed vent system” refers to a system in which air pollutants produced by process equipment are effectively trapped and sent to pollution control equipment, so that the conveyed gases are in indirect contact with the atmosphere. Such a system shall include piping and connecting devices.V. “Discharge pipe emissions per unit hour” (herein referred to as “discharge pipe emissions”) refer to air pollutant emissions from a single discharge pipe; measured in units of kg/hour.VI. “Pollution control equipment treatment efficiency” (herein referred to as “treatment efficiency”) refers to the percentage reduction in air pollutant emissions after treatment by pollution control equipment, and is calculated on the basis of emissions concentration and emissions volume measured synchronously before and after pollution control equipment using the following formula: Treatment efficiency = ((E ? E0) / E)×100% ; measured as %. I.E: air pollutant emissions per unit hour entering the front of pollution control equipment via the closed vent system; measured in units of kg/hour. II.E0: air pollutant emissions per unit hour discharged directly into the atmosphere from the back of pollution control equipment; measured in units of kg/hour.VII. New processes refer to processes established following the date of announcement and implementation of these Standards.VIII. “Existing processes” refer to processes that had already been completed, are under construction, whose project tender request procedures had been completed, or if no tenders were invited, whose project contracts were given out and signed before the date of announcement and implementation of these Standards. Existing process complying with the change criteria prescribed in Article 3 of the Stationary Pollution Source Installation and Operating Permit Management Regulations shall be considered new processes, however.IX. “Usage quantities” refer to the usage quantities of raw materials containing VOCs, hydrofluoric acid, or hydrochloric acid used in processes as solvents, resins, or in other forms.X. “Output quantities” refer to output quantities of process VOCs, hydrofluoric acid, or hydrochloric acid discharged with waste solvent, wastes, wastewater, products, or in other forms.XI. “Effective quarterly monitoring time percentage” refers to a monitoring facility’s ratio of effective monitoring time each quarter, and is calculated using the following formula: T -(Du +Dm) P = ────── ×100% T -tI. P: effective quarterly monitoring time percentage; measured as %.II. T: stationary pollution source quarterly operating time; in units of hours.III. t: monitoring facility replacement time; in units of hours.IV. Du: monitoring facility effective data time; in units of hours.V. Dm: monitoring facility lost data time; in units of hours.
