EDMONTON — A new database that compiles thousands of government and industry records on Alberta’s oilsands lays out in painstaking detail how the industry is a constant source of low-level pollution to the area’s land, air and water, says the scientist who pulled it all together.

And Kevin Timoney, who plans to release the vast information trove publicly on Friday, say the records suggest the province isn’t doing enough to enforce environmental regulations.

“You start to see hundreds and hundreds of fairly serious (emissions) well above the regulated guidelines and nothing’s done,” said Timoney, an ecology consultant who has been an oilsands critic in the past.

“You go and look at the next month and nothing’s done. The same pattern continues month in, month out, year in, year out.”

Timoney spent the last eight months compiling the records from provincial and federal government libraries covering the period from the mid-1990s to 2008. The records include regular industry reports, industry self-reporting on specific incidents, public reporting of suspected incidents, and federal data.

Some of those records were public, although buried in hard-to-find government files. Most of the records had to be obtained using federal and provincial freedom of information legislation.

The result is a database that takes up 14 megabytes of computer memory. Timoney says this is the first time so much information about the oilsands industry’s environmental performance has been gathered together in one place in a searchable form.

It documents thousands of infractions of the province’s environmental regulations. Some are small, some aren’t.

But the database’s search functions reveal patterns in the mass of raw data. There are many cases of companies reporting the same violations month after month.

One company reported that its emissions of H2S — so-called “rotten-egg gas” that is toxic in very small amounts — exceeded guidelines for 15 hours in March 2008. The next month, it exceeded them for 51 hours and the next month for 28 hours.

Another company reported violations of surface water guidelines at least once a month from January to July 2008.

Some of those were minor, such as muddy water being released due to ditch-digging on site. But one month, 5.4 million litres of salty water were mistakenly released into the Athabasca River.

The database mentions a chlorine release that caused burning eyes and breathing problems for workers. It records that sour water released into a tailings pond resulted in high H2S levels in the air for nearly six days.

Alberta Environment spokeswoman Jessica Potter defends the government’s enforcement record. She said many of the incidents in the database are records of calls from the public, which may not bear up under scrutiny.

“We follow up on every call that comes in,” she said. “Not every call is going to result in a regulatory action. It might not even be an issue.”

Potter said the government recognizes the need to be more open and is planning to unveil a similar database of its own this fall.

“It’s a matter of working toward improving transparency,” she said. “We keep putting more and more on the web, we just can’t do it all at once.”

Melina Laboucan-Massimo of Greenpeace, which helped fund Timoney’s work, said the database gives the public the first coherent look at the entire environmental costs of the oilsands.

“There are all of these consequences and I don’t think people in Alberta hear about it,” she said. “People need to know this is happening on a monthly basis. There’s very big consequences.”

Greenpeace is one of the groups that plans to make the database available online, either through a computer site or on a DVD.

The Sierra Club Prairie, Keepers of the Athabasca and Global Forest Watch Canada are also involved with the project.
