Canadian Tar Sands Pollution Moves South to US Refineries

But it's not just new US refineries. It's retrofits, too. Also in the works are plans to retool 800,000 bpd of existing US refining capacity to process Tar Sands oil from tar sands. Meanwhile, US conventional crude refining capacity is experiencing a net drop of more than 300,000 bpd.

This shift is detailed in a June 2008 report jointly released by the DC-based Environmental Integrity Project and Canada's Environmental Defence. According to this report, here are the states that would play host to Tar Sands refineries: IL and TX (495,000 bpd total), IN (205,000 bpd), LA (180,000 bpd), MI (15,000 bpd), MT (13,000 bpd), ND (65,000 bpd), OH (316,120 bpd), OK (44,700 bpd), SD (400,000 bpd), and WI (200,000 bpd).

For communities near these new or retooled refineries, the pollution increase will likely be considerable. EIP/ED note that refining the "extra heavy sour" crude oil extracted from tar sands would yield higher air emissions of sulfur dioxide, hydrogen sulfide, sulfuric acid mist, nitrogen oxides, and toxic metals such as lead and nickel compounds.

Several US environmental laws and regulations govern the potential environmental impact of this refining capacity expansion. It'll be worth watching closely to see how stringently and consistently they're enforced.

Right now, while these facilities are in the permitting process, EPA is required to apply the New Source Performance Standards (NSPS) to regulate greenhouse gas emissions to newly modified or constructed oil refineries. These can be found in the Code of Federal Regulations (CFR), part 60, subpart Ja (Federal Register: 73 FR 35867, June 24, 2008).

In this process, EPA also can consider alternatives to tar sand oil feedstock when making determinations for "best available control technology" (BACT) and "lowest achievable emission rate" (LAER) under New Source Review (NSR) provisions of the Clean Air Act. The NSR process also allows EPA to consider increased air emissions of SO2, H2S, sulfuric acid mist, NOX, and toxic metals.

You can follow these actions via EPA regional offices. EPA HQ press: Cathy Milbourn, 202-564-4355. Current EPA emissions guidance for refineries.

In June 2008, EPA forced Encana Corp. and ConocoPhillips to revise their plans for expanding a planned Tar Sands refinery in Roxana, IL over clean air concerns (NRDC release). As of Sept. 25, 2008, this project was approved for construction.

State environmental agencies also will need to issue permits for new or expanded refineries. Also, the pipelines that would carry the crude from Canada to the new refineries also need US environmental permits. This could involve various federal agencies such as BLM, as well as state and local governments.

Perhaps the main reason why new US refineries are once again being built after a three-decade hiatus is the current political urgency around energy security, especially reducing dependency on foreign oil. On May 12, 2008, FactCheck.org answered the question, "Does the U.S. lack sufficient oil refining capabilities?"
