LETTER: Local doctors concerned about ferrochrome want you to know about our current cancer rates

52 local doctors want to know exactly what Noront plans to do to protect Saultites from Chromium VI should they commission a ferrochrome smelter in the city

SooToday received the following letter from Dr. Rob Suppes on behalf of doctors concerned about a proposed ferrochrome smelting plant:

Should Sault Ste. Marie have a ferrochrome smelter built in the city? This is a critical question facing our community.

A smelter would provide direct economic benefit to several hundred people and to associated businesses. We physicians are very concerned about the risk of contamination of the surrounding environment with chromium VI, a by-product of smelting that is a known cancer-causing agent.

The smelter is to be located next to the Steel Mill, within the city and next to a major waterway, increasing the risk to our population.

Such an important decision requires that our community understand these risks so they can better assess the costs and benefits of bringing this smelter to Sault Ste. Marie. Citizens need to be made aware of several facts.

As such, after considerable research, we present a number of these facts here:

  1. Compared to other cities in Ontario, Sault Ste. Marie has increased rates of lung, bronchus, bladder, kidney, renal pelvis, and esophageal cancers (1,2).
  2. A 2019 study showed that the rate of Acute Myeloid Leukemia was 50 per cent higher in Sault Ste. Marie than in the rest of Canada. The rate was more than double the Canadian average for those living in the P6C area code around Algoma Steel (3).
  3. Chromium VI, a known cancer-causing agent, is produced even in the cleanest ferrochrome smelting production (4). Research demonstrates that exposure increases the risk of multiple cancers: liver, kidney and female genitourinary, lung, lip, oral cavity, pharynx, stomach, female breast, female colon, prostate, and leukaemia (5).
  4. These cancers were the result of exposure to both welding fumes and contaminated drinking water.
  5. Chromium VI is dangerous for humans and increases the risk of cancer and subsequent death with increased exposure over time (6).
  6. Much of chromium VI waste is contained in slag ponds (4); there are no data on how safe such ponds would be in Sault Ste. Marie’s unique climate. Many of the health risks of chromium VI show links to airborne contamination (4, 7, 8, 9).
  7. Noront has released details of the proposed smelter for Sault Ste. Marie stating that the basis for the design will be the ferrochrome smelter in Tornio, Finland (10,11). This smelter, which is currently the most advanced in the world, has significant documented pollution of the surrounding environment with carcinogenic chromium VI (7,8, 9).
  8. There is currently no ferrochrome smelter in the world that doesn’t contaminate the surrounding environment; even the most technologically advanced smelter releases some chromium VI (4).
  9. Current Ontario law requires self-reporting by heavy industry, but many of these industries circumvent these regulations by paying relatively small fines for infractions or applying for exemptions from environmental regulations (12,13).

At this time, we have no idea if or how Noront plans to address the above issues.

Before citizens can make an informed decision, Noront must answer difficult questions with detailed explanations and plans. Noront must provide scientific evidence to back up any claims that are not substantiated by scientific research or evidence from other ferrochrome smelting facilities.

Noront is hosting a consultation on Oct. 23 from 3-8 p.m. at the Delta Sault Ste. Marie Waterfront. We hope the information provided here better prepares the citizens of this city to demand answers.
