The purpose of this guidance is to: document factors used by the Director to determine if a nonscheduled substance is; delineate remedial requirements to ensure a NSTS does not exceed a concentration in excess of that acceptable to the Director.

The Canadian Environmental Protection Act (CEPA) proclaimed in 1988 requires the Canadian Ministers of the Environment and of National Health and Welfare to assess the toxicity of different substances, including Polycyclic Aromatic Hydrocarbons (PAHs). PAH emissions from different sources were inventoried to determine their entry in the environment. Concentrations in the different media (air, water, sediment, biota) were obtained, which indicated the extent of exposure. Laboratory testings showed effects caused by PAHs, some of which were observed in the nature. The inventory of the sources revealed that more than 6300 t of PAHs were released in the Canadian environment in 1990, mostly to the atmosphere (4300 t). Forest fires represent the single most important natural source of PAHs (2000 t/year) while anthropogenic sources are numerous and result in emission into all media. They include combustion sources (Heating, Incineration), industrial sources (Aluminum smelters, Iron and steel industries) and transportation.

This is the summary of proceedings for a two-day workshop on reformulated fuels held in Vancouver in 1994. The participants represented some of the most highly qualified people in the area of vehicle emissions. The Government of the Province of British Columbia is committed to the maintenance and enhancement of air quality in the province. As part of a wide range of initiatives to address air quality issues the Ministry of Environment, Lands and Parks has announced that it is reviewing all North American fuels and vehicles standards, including California's, as a basis for determining a solution appropriate for British Columbia. The purpose of the two round table meetings is to provide a forum in which stakeholders can provide information and comments on technical aspects of various fuel reformulations. It is hoped that the major technical points and issues can be identified through the presentation and discussion phase and carried forward to an open discussion and wrap-up at the end of each day. The results of the discussions will be important to the Ministry's assessment of the low sulphur diesel and reformulated gasoline issues leading ultimately to policy positions, voluntary initiatives, and if necessary, regulations.

I should note at the outset that management of contaminated sites within the provincial
government has been split across two ministries. The Ministry of Water, Land and Air
Protection continues to lead the regulation of contaminated sites assessment and clean up
in BC. The Ministry of Sustainable Resource Management has been tasked with the
administration of contaminated crown land in BC. This distinction has been made to
separate the province’s dual role of regulator and land owner.
Early last year we reorganized the contaminated sites program. Probably the single most
significant change is to place all ministry staff across the province, who are involved with
contaminated sites regulation, into a single organizational unit. In the past, reporting
lines were different in the regions and headquarters. Now, all staff are managed by a
single assistant director who reports to the Director of the Environmental Management
Branch. Staff responsibilities are organized by function rather than geographic area.
This has enabled us to improve the delivery of consistent services with greater certainty
for our clients.

The objective of this preliminary study was to compare the relative acute toxicity and water chemistry of leachate from different species of wood waste typically landfilled or used as cover in landscaping or equestrian facilities in the Lower Mainland of British Columbia. Comparisons of the relative toxicity of wood waste (mostly bark and sapwood) leachate from six different tree species, red cedar, yellow cedar, sitka spruce, Douglas fir, western hemlock, and black cottonwood, were made for Microtox, 96-hr LC50 rainbow trout and 48-hr LC50 daphnia magna bioassays. The leachate from different species were generated concurrently in a laboratory by statically soaking the wood waste in a leachant of de-ionized water for 28 days. Dissolved oxygen, pH, conductance, chemical oxygen demand, acidity pH 8.3 and Microtox were monitored throughout the course of the experiment. A number of other water chemistry parameters were also monitored at the end of the 28 day experiment. The results in this report were based upon a limited number of samples and further research would be needed to substantiate the findings.

Wood Lake has been identified in a number of previous studies as having poor water quality relative to the other lakes of the Okanagan Valley. This poor water quality prevents the water-based recreation potential from being achieved and affects the sport fishery potential. The water quality of the south end of Kalamalka Lake has also been affected by the inflow of high concentrations of nutrients from Wood Lake.

Windermere Lake was cored on July 23, 1998 by Rick Nordin and Les MacDonald. The core was retrieved using a modified K-B corer (internal diameter ~ 6.35 cm) from the deep basin. On shore the core was sectioned into 0.5-cm intervals into 120-ml plastic containers. These samples were shipped on ice to Queen's University where they were stored in our coldroom at 4* C. Each container was weighed to determine the total wet weight of sediment then subsampled for 210Pb, diatom and pigment analyses. Twenty intervals (every 2 cm) were subsampled for diatom and pigment analyses, and sixteen intervals for 210Pb analysis. Subsamples for analysis of pigments were sent to Prof. Leavitt at University of Regina. Prepared samples for 210Pb analysis (see below) were sent to MYCORE Ltd.

On July 23, 1998, staff from the Ministry of Environment, Lands and Parks took a core sample of bottom sediment from the deepest point in Windermere Lake, off the Akiskanook resort. The core was subsampled and underwent diatom, plant pigment, 210Pb dating, and metallic element analyses. The intent of this work was to determine whether Windermere Lake water quality has changed over the recent past. Results show that water quality began to change around 1950, concurrent with population growth. There is some evidence of slight eutrophication. This report includes some discussion about the reasons for down-core change and whether human settlement may be a cause.

Williams Lake drains west to the Fraser RIver via the Williams Lake River. The San Jose River is the main tributary to Williams Lake. The rive rbegins at the outlet of Lac la Hache and flows for approximatgely 55 km through the San Jose Valley. There are three major tributaries to the San Jose River: Borland Creek, Jones Creek, and Knife Creek.
