Standards for Determining Specific Items and Scope of Environmental Impact Assessments for Development Activities. Article 49
Any development activity undertaken within a development activity (or project) for which the environmental impact assessment review (approval) has been completed shall be exempt from environmental impact assessment when complying with the regulations in the following subparagraphs:I. The industry type is consistent with the original approval.II. The developer in charge of the development activity (project) has confirmed that the originally-approved total pollution has not been exceeded. However, when the discharge of any one pollutant accounts for more than 20% of the total approved volume of that pollutant, or the annual discharge of any one pollutant type among the items of particulate pollutants, nitrogen oxides, sulfur oxides, or volatile organic compounds exceeds 100 tons, approval from the competent authority of the target project and the original competent authority of the target project for the environmental impact assessment case is required.In the foregoing paragraph, the developer in charge of the development activity (project) shall implement total pollution controls, and shall report total pollution emission quotas to the local competent authority on an annual basis.With regard to the development activity in Paragraph 1, if the original environmental impact assessment review (approval) does not determine the industry type or total pollution amount, the developer may apply for a change as prescribed in Article 16 of this Act. After the industry type and total pollution amount have been included, and review (approval) completed, the various development activities in the project shall be subject to the regulations in Paragraph 1.
中文原文 開發行為應實施環境影響評估細目及範圍認定標準第49條
於經環境影響評估審查（核）完成之開發行為（計畫）內，其內之各開發行為符合下列各款規定者，免實施環境影響評估：
一、產業類別符合原核定。
二、經開發行為（計畫）之開發單位確認未超出原核定污染總量。
但任一污染物排放量達該項污染物核定總量百分之二十以上或粒狀污染物、氮氧化物、硫氧化物及揮發性有機物任一排放量達每年一百公噸以上者，應經目的事業主管機關及原環境影響評估案件之目的事業主管機關同意。
前項開發行為（計畫）之開發單位，應執行污染總量管制，並每年向當地主管機關申報污染總量核配情形。
第一項之開發行為，原環境影響評估審查（核）未核定產業類別或污染總量者，開發單位得依本法第十六條規定辦理變更；於納入產業類別或污染總量並經審查（核）完成後，其內之各開發行為，適用第一項規定。
