Some more documents for those interested in KIP Costanza. These are very large pdf’s and technical.
The coal hill waste site reflects years of man-made pollution of the coal production in the area. The list of contaminated materials includes the following: copper, arsenic, cadmium, lead, zinc, barium, mercury, chromium, manganese, aluminum, and iron; all in excess of the safe standards for BC Contaminated Sites Regulations. There are also elevated arsenic and polycyclic aromatic hydrocarbons (this is a long chain carbon that doesn’t break down in water and thus has a long-term toxicity). In addition, chemicals present at the coal hills (acenaphthene, anthrasene, chrysene, fluorine, 2 methylnaphthalene, naphthalene and phenanthrene) are in excess of BC Sediment Quality Criteria.

@Paul: The only change I’ve seen since 1994 is the reshaping of the east side for Washer Creek and the use of SkyRocket as a topping in the same area.
Truckloads of rock/gravel were also brought in the flat area just beyond the KIP shack. Some of this material has since been trucked out for use behind the Post Office.
