On July 8, 2018, Yichang Wuxing Material Technology Co., Ltd., based on the "Yichang Wuxing Material Technology Co., Ltd. Heat Supply and Motor System Energy-saving Comprehensive Renovation Project Completion Environmental Protection Acceptance Monitoring Report Form" and compared it with the "Construction Project Completion Environmental Protection Monitoring Report Form" "Interim Measures for Acceptance", in strict accordance with relevant national laws and regulations, technical specifications/guidelines for environmental protection acceptance of construction projects, environmental impact assessment report forms for this project, and approval from the approval department, the project is checked and accepted, and the opinions are as follows:

1. Basic situation of project construction

(1) Construction site, scale and main construction content

In order to reduce energy consumption, improve energy efficiency, and reduce environmental pollution, Yichang Wuxing Material Technology Co., Ltd. (formerly known as Yichang Wuxing Decorative Panel Co., Ltd.) built heating and motor systems in the existing plant area in Mingfeng Town, Yuan'an County. Comprehensive renovation project. The main construction content of the project includes the transformation of heat conduction oil furnace, the transformation of waste heat system and the transformation of motor frequency conversion.

(2) Construction process and environmental approval status

In February 2012, the Yichang Environmental Protection Research Institute completed the "Environmental Impact Report Form for the Energy-saving Comprehensive Renovation Project of the Heating and Motor System of Yichang Wuxing Decorative Board Co., Ltd."; Yuan’an Environmental Protection Bureau Yiyuan Huanhuan [2012] On the 7th, the "Letter of Yuan'an Environmental Protection Bureau on the Pre-examination Opinions of the Environmental Impact Report Form for the Energy-saving Comprehensive Renovation Project of the Heating and Motor System of Yichang Wuxing Decorative Board Co., Ltd." was issued; Yichang Environmental Protection Bureau used Yishi Environmental Examination [2012 ] On the 26th, the "Approval of the Municipal Environmental Protection Bureau on the Environmental Impact Report Form of the Energy-saving Comprehensive Reform Project of the Heating and Motor System of Yichang Wuxing Decorative Board Co., Ltd." was issued.

The construction of this project started in September 2012 and was completed in August 2016.

(3) Investment situation

The actual total investment is 15 million yuan, of which the actual environmental protection investment is 500,000 yuan, accounting for 3.33%.
