     In accordance with the “Science and Industrial Park Sewage Sewerage System Discharge Standard” announced in the EPA Document Code No. 1010090484 promulgated by the Environmental Protection Administration, Executive Yuan, ammonia nitrogen was added to the existing 33 restricted items while biological toxicity was moved to the Water Pollution Control Measures and Test Reporting Management Regulations to allow standardization.
     The restriction period of Ammonia nitrogen is classified into two stages; the restriction limit of the first stage is 75mg/L, implemented on July 1, 2013. If inspections determine that project improvement must be conducted, a management plan for the reduction of pollutants present in the effluent discharge must be submitted. At the same time, organizations that submit the plan for approval by the county (city) competent authorities and implement the improvements in accordance with the plan before June 30 2013, the restriction will take effect on January 1, 2015. The restriction limit of the second stage is 30mg/L, which will take effect on January 1, 2017. The ammonia nitrogen reduction of the Hsinchu Science and Industrial Park, Zhunan Base, and Longtan Base sewage treatment plants under the management of the Park Administration were required to conduct a comprehensive measure improvement assessment of the current processes and sewage treatment equipment (facilities). The process requires a long buffer period as it is very difficult to lower the concentration of ammonia nitrogen in the water quality of the discharged effluent to the restriction limits of the first stage before July 1, 2013, therefore our Company assisted the Park Administration in proposing a reduction plan and compiled a “Management Plan for the Reduction of Ammonia Nitrogen Present in Discharged Effluent”. The Plan was submitted to the competent authorities for approval in the expectations of extending the deadline for implementation of ammonia nitrogen restriction to January 1, 2015.
