ASE Announces Facts Regarding Operations of Chungli No.1 Packaging/Testing Site

Advanced Semiconductor Engineering, Inc. ("ASE" or the "Company") announces the following facts in connection with the operations of its packaging/testing site No. 1 in Chungli, Taoyoun, Taiwan (the "Chungli No.1 packaging/testing site")

ASE explains that the operations of the Chungli No.1 packaging/testing site at the Company's Chungli branch remain unaffected:

At 7:30 p.m., December 14, 2013, the inspectors from the Taoyuan County Environmental Protection Bureau came to the Chungli No.1 packaging/testing site for an on-site visit to sample disposed wastewater discharged from the Chungli No.1 packaging/testing site. Initial inspections did not result any violation of the regulations. The inspectors then proceeded to examine the documents, and also inspected the wastewater treatment facilities. The details of the findings of the inspectors and ASE's responses are described in the following:

1. The inspectors found pipes on the wall of the sedimentation tank connecting the wastewater collection system's collection tank and the sedimentation tank. The wastewater recycle system's collection tank are part of three wafer saw machines located on the 4th floor of Building B of the Chungli No.1 packaging/testing site. The inspectors were of the view that wastewater from the wafer saw process could potentially be directly discharged into the sedimentation tank without permitted proper treatment which is in violation of Article 18 of the ROC Water Pollution Control Act. Pursuant to Article 52 of the Water Pollution Control Act, the Company is ordered to make necessary improvements by 5pm on December 16. 2013.
2. The wastewater discharged from the said treatment facilities was sampled by the inspectors from the Environmental Protection Bureau, and all inspection results are satisfactory without violating the wastewater disposal regulations: The temperature of the wastewater was 26 Degrees Celsius (the upper limit of the standard range is 35 Degrees Celsius); the pH level was 8.07 (the standard range is 6-9); and the conductivity was 8us/cm; the heavy metal contaminants were zero.
3. The three wafer saw machines in question were newly installed in October 2013.  The Company followed the inspectors' instruction to immediately stop the disposal of wastewater into the sedimentation tank and remove the extra pipes. The three wafer saw machines have been shut down, and the said pipes were removed. The Company has completed the improvement and complied with the demands from the Taoyuan County Environmental Protection Bureau.
4. Clause 12, Article 2 of the Water Pollution Control Measures and Test Reporting Management Regulations, when enacted on October 16, 2006, defined bypass of wastewater disposal as "wastewater disposed through discharged point without permission, or discharged point that are not certified by the official sewer departments, into the sewer." The clause was subsequently amended on March 8, 2013, which now defines the bypass of wastewater disposal as "wastewater disposed through uncertified collecting points, processing units, and discharge points, or through discharge points that are not certified by the official sewer departments, into the sewer." As such, the definition of bypass of wastewater disposal has been expanded to include "collecting points and processing units." The responsible staff of the Company was not aware of the modification, and thus disposed the recycled water from the said manufacturing process through aforementioned pipes into the sedimentation tank. However, all the wastewater was disposed through the Company's certified discharge points with water meter and water quality monitoring system. There is no uncertified discharge point currently installed.
5. The Chungli branch of the Company has invested about NT$1 billion during recent years in pollution control and wastewater treatment facilities.
6. The inspectors from the Environmental Protection Bureau only ordered that the three wafer saw machines to be shut down immediately for improvements, and did not in any way order suspension or shut-down of the entire Chungli No.1 packaging/testing site.
7. The Company has completed the improvements as ordered by the Taoyuan County Environmental Protection Bureau. The report about the improvements will be sent to the Taoyuan County Environmental Protection Bureau by Monday, December 16, 2013 and the Company will apply for a re-examination for the Chungli No.1 packaging/testing site.
