The project aims to 1) draft total-quantity-control plans and its subsidiary legislation, 2) evaluate the implementation of total-quantity-control plans, and 3) conduct cost-benefit analysis for total-quantity-control plans. In order to achieve the objectives, the project has completed the regulation amendments, implementing air quality improvement actions and pilot program, air quality standard recommendations for PM2.5 and HAPs, socio-economic assessment, as well as international information research. The details of the works are listed as below:
Amendment proposal and subsidiary legislation: Under the Air Pollution Control Act, the country has implemented several prior total-quantity-control regulations and programs, such as Prevention of Significant Deterioration(PSD), air quality modeling, and non-attainment area management. However, constrained by the provision of article 8~12 of Air Pollution Control Act, the implementation of total quantity control plans is restricted. As such, the project proposes an amendment to overcome the barrier in implementing total control plans.
Acting on Total-quantity-control plan: It is suggested in the project to divide the western Taiwan by Mt. Huoyan into two zones: the north and the south, where includes Yun-Chian-Nan, Kao-Ping air quality zones.
Offset Mechanism Design and Capacity Building: We referred to CDM and New Sources Review of USEPA, and proposed a set of principles for offsetting air pollutants for EIA. We held workshops and conducted a survey to evaluate effectiveness of the emission-reduction pilot program to the stationary sources. We also recommend create a platform for disseminating Emission Reduction Credits information.
Suggestions of PM2.5 and HAPs standard-setting: A national Master plan of PM2.5 was created based on the literature research. In addition, the project suggests not to set any Hazardous Air Pollutants air quality standard in short-term, such as Dioxin、Organic HAPs、heavy metals.
Cost-benefit Analysis: Dr. Tseng used ARCoB Model to perform cost-benefit analysis for PM10 and Ozone control program with the data of funding for control measures, air quality monitoring and local medical costs statistic from 1997 to 2007. The result shows that an annual PM10 reduction by 0.49μg/m3 results in a saving of NT$4,027,000/yr on medical expenditure. In contrast, an annual increase of 0.94μg/m3 of O3 concentration leads to an increase of NT$998,000/yr on medical expenditure.
As mentioned above, we also compiled latest international information and conducted literature review to implement the works more efficiently.
