Water pollution control fees were collected from 11,096-11,173 companies during 2021; the total of approximately NT$503.16 million collected, enterprise (not including livestock operations) and industrial area wastewater sewage systems accounted for roughly 76%, and livestock operations accounted for roughly 23%; and other wastewater sewage systems for designated areas or premises accounted for approximately 1%. The collection items accounting for the largest shares of total fees were COD (accounting for roughly 78%) and SOx (roughly 14%).
A total of NT$2.64416 billion has been collected since the start of fee collection in 2015. With regard to changes in emissions volume, COD and SS emissions volumes displayed slight decreasing trends. While there have been minor year-to-year differences in emissions volume for 8 types of substances hazardous to health, they have generally had decreasing trends. Because emissions of these substances are chiefly derived from the sewage systems of large enterprises and industrial areas, their emissions volumes tend to be influenced by variations in the reported inspection values for individual wastewater sewage systems with large effluent discharge volume.
This project completed review work for the reports submitted by 3,008 companies and on-site audits at 160 companies; approximately NT$75.42 million in supplementary fees were paid. With regard to water pollution control fee collection account checking, a CPA was hired to audit water pollution control fee accounts and issue professional audit reports. The reporting system's functions relating to controlled areas whose reports were overdue by more than 90 days and smart reporting case review functions were expanded, and were made compliant with the Environmental Protection Administration's information security operating requirements.
The revised draft water pollution control fee collection regulations included such improvements as the addition of an ammonia nitrogen fee collection item, the elimination of the preferential discount for the heavy metal item, and adjustment of water pollution control fee reporting and fee payment schedule. It is recommended that future legal revision efforts take the impact on industry and the time needed for reporting system establishment and awareness tasks into consideration.
