For air quality index, good and fair (AQI≦100) level had percentage of about 92.0%, The percentage of AQI>100 was 8.0%, and index pollutant was PM2.5 and O3 8 hours. According to emergency prevention method of serious air quality worsening, a total of air quality worsening alarms of 58 times was activated, and emergency response actions of air pollution source checking, handling and reporting were conducted.
In 2018, 13 items of effectiveness management of air pollution fund consignment project were implemented, and a committee for air pollution fund was held to review the implementation effectiveness of the project.

In order to promote the change of boiler’s fuel to cleaner fuel such as natural gas, the present operation situation of 196 boilers were surveyed, and the network drawing for natural gas pipeline was set up, meanwhile, plant with willingness for improvement was selected for making burning efficiency and heat loss survey for the boiler so as to evaluate the economic effectiveness for changing to natural gas. And the instructed targets included Taihong Circuit Ind., TOA Resin Corporation and SEKISUI, and outsourcing for natural gas replacement plan and setup engineering has been finished, and operation will be expected to be in 2019.
In order to encourage the public to use Clean Air Zone, Jui-Kuang Clean Air Zone has been applied as environmental teaching facility and site for implementation of environment teaching training course, meanwhile, sketch competition for students in the Hsinchu and Miaoli air quality zones was implemented. Growth history database for arbor was set up, and two dimensional barcode was hung on the bole of the tree as tour guide for the public. In this year, greening plan for setup of sanitary landfill site for land number 59, 76 and 77 for Cheng-Kung section of Hsinpu township and river highland beach (first term) clean air zone setup plan of Touqian River were submitted to environmental protection bureau, after finishing the construction, there will be 14 clean air zones in this county, and the area will be added to 74.72 hectares.
