This plan was implemented on October 25, 2011, and ended on October 24, 2011. The plan was implemented for 365 days in total. The summary of the work results is as follows:
Inspect the rivers and rivers prone to dust exposure
Execute once a month inspections are currently carried out 12 times (November 2010-October 2011), exposed areas prone to dust, 17 exposed areas in the Hualien River Basin, 2 exposed areas in the Liwu River Basin, Xiuguluan There are 4 bare lands in the stream basin, a total of 23 bare lands. According to statistics, the bare lands total 645.4 hectares, the green coverage is 264.3 hectares, and the water coverage is 510.1 hectares. The competent authority will implement the dust control method on 69.7 hectares this year, record the results of monthly inspections and explain the changes in the riverbed.
Dust early warning system maintenance

The hourly monitoring data will be built on the above webpage for query. The data analysis report record form of the automatic monitoring station will be sent to the Bureau for reference before the 10th along with the monthly work report.
Road cleaning operations
Cooperate with the street washing operation during the dust-prone period of the river to reduce the health hazards of the dust to the public. The street washing locations are Xincheng Township, Shoufeng Township and Yuli District. 4,100 kilometers of street washing, 600 kilometers of street washing were adopted by the promoters, and the total length of street washing in the year was more than 4,700 kilometers. 600 kilometers of streets, 687.6 kilometers from October 25, 2010 to October 24, 2011 has been achieved, and the achievement rate has exceeded the completion target. A total of 4,757 kilometers of streets have been cleaned in this plan year.
River dust education publicity meeting
Touring villages, communities, campuses or patrol teams to conduct education promotion meetings, this year has completed 2 sessions with a total of 128 people participating.
Website maintenance and update
Before the 5th of each month, update and maintain the website information of the "Hualien County River Dust Warning and Notification Platform" and the Environmental Protection Agency's "River Dust Prevention and Promotion Information Platform". Look at the maintenance of the data background and upload the results of the project implementation, and update the website data for 12 months after completing the project period.
Emergency response drill for river dust incident in Hualien area
On March 25, 2011, Hualien River management units, relevant bureaus of the county government, and various assisting units were invited to carry out the "Emergency Response to River Dust" at the square next to the dredged road under the Donghua Bridge in Shoufeng Township (Jiuhe Bureau Zhixue Storage Yard) Defense Drill". Simulate the situation of dust in rivers and rivers. Response units at all levels participate in live drills to strengthen familiarity with the reporting process and division of powers and responsibilities of incidents, so as to achieve the effect of daily response to dust.
Demonstration meeting for improvement of exposed rivers
It was held at 13:30 on March 25, 2011 at Hualien River (next to the Shoufeng Monitoring Station). A total of 42 people participated in the course. Level of participant feedback on the course.
River dust regional liaison meeting
The control of dust in rivers is based on cross-unit cooperation. Through experience exchange and discussion, relevant measures for dust suppression are formulated to reduce the hazards caused by dust. On March 14, 2011 and July 15, 2011 at the conference room on the 4th floor of the Environmental Protection Bureau of Hualien County. All major river management units in the county are invited to hold this liaison meeting to discuss the effectiveness of the dust raising method and the division of responsibilities of each unit. Through work discussions and experience sharing, the relationship between them is enhanced. Through professional experts and scholars, valuable professional suggestions are put forward for the county's river dust improvement policy, reducing the probability of river dust occurrence; if each unit has relevant activities, it can be notified in the group, related prevention actions and publicity, etc. Activities should also be disclosed in the media, so that the public can have a positive impression and improve public satisfaction.
Evaluation and analysis of dust control methods in bare rivers and rivers
Evaluate and analyze construction methods and suggested practices suitable for Hualien County, and provide follow-up follow-up and suggestions for the prevention and control of river bare land by river management units, which can be used as reference materials for the county (including river management units) to promote the prevention and control of river dust. The relevant information has been published in On April 15, 2011, it was submitted to the authority for approval.
Classification of nudity prone to hair over the years
In order to grasp the changes of bare land over the years, collect relevant data, understand the change of bare land, and delineate the level of dust-prone areas. However, besides the weather, the main factor causing dust in rivers is that the area of bare land is too large, which is an effective supervision and suppression Changes in the area of bare land in dusty rivers. In addition to regular monthly inspections and records of exposed land, this plan also includes tracking of river improvement operations for river management units, and observes the corresponding causal relationship between the growth and decline of bare land and dust generation year by year, and reports on the regional Contact the meeting to report the opportunity and provide suggestions for the river management agency to carry out dust control methods.
Innovative approach
This plan was submitted on November 11, 2011 to "Xiuguluan River Real-time Monitoring" as an innovation of this year to be prepared by the bureau. After approval by the Environmental Protection Bureau, the monitoring of Liwu River and Hualien River has been completed in 2011. The system and equipment upgrades were completed on December 31, 273 days until September 30, 2011. In addition, a real-time surveillance system for the Xiuguluan River was added this year, and the test setup was completed on February 10, 2011. Such integration of the three CCTV stations can shorten the response time for river dust.
Dust early warning notification system
The PM10 automatic monitoring stations of this plan are set up in Hualien River, Liwu River and Xiuguluan River to monitor the change of dust concentration in rivers. The monitoring station will send an early warning notification message if the PM10 of the monitoring station reaches 100 μg/m3 or more per hour. 605μg/m3 and last for more than two hours, immediately start the strain mechanism.
In addition, according to the weather conditions, the early warning score of the dust in Liwu Creek, Hualien Creek and Xiuguluan Creek for the next three days will be divided into three levels: green, yellow and red:
1. Green grade 0~19 points - the probability of river dust occurrence is low, and no action is required.
2. Yellow level 20~26 points - There is a risk of river dust. The day before, notify the relevant units to be on standby through the communication software, monitor through CCTV (Liwu Creek, Hualien Creek) and invite environmental protection volunteers or the planner in the morning and afternoon of the same day The painting personnel inspected the site for dust, and if there is dust, please ask the relevant units to take measures to suppress the dust.
3. Red level -27 points or above, or high probability of dust occurrence (yellow light 25-26 points). The day before, please ask the local TV station to perform a marquee to remind residents near the dusty river section to take protection work.
Statistics From October 25th, 2010 to October 24th, 2011, the project carried out dust forecasts for a total of 365 days, with a total of 1,095 forecasts, including 1,051 forecasts for green lights and 44 forecasts for amber lights.
