SESSION 1 PULP MILL EFFLUENT ISSUES

Fraser River Action Plan 3rd Research Workshop Program Overview Industrial Discharges, Fraser River Pollution Abatement Program V. Au Environment Canada The Industrial Discharges section of the Fraser River Pollution Abatement Office (FPAO) has conducted numerous projects over the last six years to meet the objectives of the Fraser River Action Plan (FRAP). Included in this program were the development of two databases, pollution prevention guidelines and best management practices, and although not discussed here, numerous wastewater characterization and toxicity studies. In particular, the objectives of the Industrial Discharges program have been to: 1. reduce the release of persistent toxic substances entering the waters of the Fraser River basin pursuant to the Canadian Environmental Protection Act (CEPA) and identified as priority from inventories and environmental data to the extent allowed by best practicable technology; 2. develop and maintain an inventory of major pollution sources and loadings to the basin; and, 3. reduce environmentally disruptive industrial effluent discharges by 30% to meet environmental quality objectives. In order to identify and analyze industrial pollution sources and meet the first objective, wastewater characterization methods were developed for industrial effluents. These methods and supporting documents were used in a series of wastewater characterization studies conducted prior to 1994. To meet the second objective listed above, two databases, Envirodat and the Fraser River Pollution Point Source Inventory (FRPSI) were developed. Both of these databases are geo-referenced and data are available upon request. Envirodat, the national environmental database, is currently used as the data storage and retrieval system for monitoring data on industrial, and potentially municipal, wastewater discharges in the Fraser River basin. In addition, Envirodat is a relational database containing laboratory and field results for a host of chemical, physical and biological variables, as well as sample location descriptions, geographic coordinates, sample collection dates and methods. Data were collected from waste management permit compliance monitoring reports, wastewater characterization studies and water quality monitoring reports. Until May 1995, wastewater monitoring data was entered, by cooperative education students, directly into Envirodat using Oracle/Vax. However, this method was slow and cumbersome, and mistakes were difficult to correct. Therefore, a user-friendly data entry interface, WWDAT, was developed in Microsoft Access. WWDAT is now used as a front-end data entry system to enter monitoring data into Envirodat via PC. WWDAT has several improved capabilities, such as quality assurance checks and simplified error correction. Data entered in WWDAT is compiled in Envirodat-formatted files which are subsequently uploaded to Envirodat in a batch operation. Envirodat can be queried and produce reports for user-specified sites, time periods and parameters in text files. WWDAT also has reporting capabilities to produce daily, monthly or annual summary reports. To date, Envirodat is estimated to contain over 130,000 monitoring data. Page 1
