1st Time Ever

I've never filed a complaint with OSHA before. 877-470-6742 The response was professionally satisfying. I plan to call tomorrow to see what happened. It was nice being able to finally use my professional knowledge again for something other than homework. It was also gratifying to hear the response after describing the problem when I used the phrase "I'm an industrial hygienist". The city building inspector was my 2nd call. 612-685-8505. A thoroughly dissatisfying call. I got an answering machine(that's not a problem). What annoyed me was the lack of any option for "immediately dangerous situation". Not even "if this is urgent, please call 911". The voice mail indicates they will try to be out within 24 hours, maybe 48. They probably won't be out until Monday. There's a gas station going in on the corner of 36th St. & Cedar Ave. I stopped by the site last night on the way home after looking a the gargantuan pit as I drove by. The place occupies about 2 or 3 lots along Cedar. There is a pit the size of a standard swimming pool. (presumably for the UST for gas) Several other trenches and pits are present. There are no fences to keep kids out. There aren't even any signs saying "keep out". The soil is soft. One of the large excavators is parked right next to the large big pit. Trenching without shoring. Two of the walls are sloped shallow enough that they might not need reinforcement. But the side with the 20 foot (6.5 m) pile of dirt?

There is a large excavator parked between two pits. It's been raining quite a bit. The soil is pretty soft. I am quite certain that someone standing at the edge of the pit would have an imminent risk of slipping in. Followed by an imminent risk of quite a lot of soil falling in after her.

Fire in the Hole!

Now this makes me wonder if they need a stationary source permit for discharging so much combustion by-products. I think I might drive by this evening with the kids. Big fire - might have the Minneapolis F.D. on hand.

Fatality: cage washer

I've never seen a walk-in version of these. This is - like just about any other occupational cause - a gruesome way to die. The story isn't new; it was brought up in my law course discussing torts. In short, a worker became trapped in a cage washer (like a giant dishwasher for animal cages) and was fatally scalded. Steam burns are horrid, horrid things. Minnesota's Dept. Labor states: "Because there's a fatality here that caused or contributed to, there's a non-negotiable penalty of $25,000 per penalty." The article cited an average of 72 occupational deaths per year in Minnesota. Details of the inspections were not made public, but each [Minnesota] OSHA citation pointed to a specific safety rule involving equipment safety: ...employees must be able to open an exit route door from the inside at all times without special knowledge or tools ... the guarding device... shall be designed and constructed as to prevent the operator from placing any part of his body in danger zone during the operation cycle. ... each machine shall be equipped so it is possible for the operator to cut off the power without leaving the position at the point of operation. I'm not clear on how that would have mitigated this specific incident. The hospital planed to contest the findings and the fines. How is it possible that fines be "non-negotiable" and yet "contestable"? My understanding has always been that 'contesting' fines generally means "pleading them to a lower amount". .

environmental clean up

Clean up of PFCs in Woodbury starts next week. .

Build it, and they will ... dump?

The MPCA (Minnesota Pollution Control Agency) is excavating the landfill in Washington County to install a modern containment system. As the Strib dubbed it, an "history-making landfill do-over". 33 acres of garbage. $20,000,000. wow. ever notice that people write $20M or $20 million? It doesn't seem so impressive without all the zeros. That has led to one of the biggest attempts to go back and undo decades-old environmental practices that the metro area has ever seen. At the bottom of the 90-foot pit, four dozers were spreading clay that will form the base of the landfill. Compactors with huge spiked rollers were smoothing it. ... The landfill will have three layers of heavy plastic liner, separated by layers of geosynthetic material. Lewis said the new landfill will hold mainly old garbage but is designed with a higher level of protection often used to handle hazardous wastes. It will have three distinct layers to prevent any contaminated water in the landfill from reaching ground water: two feet of compacted clay at the bottom, three layers of heavy plastic above that, and two feet of sand and a collection and drainage system above the liners. an MPCA senior engineer, said no surprises have come to light so far in the nearly 300,000 cubic yards of waste removed. -- now, that in itself is a surprise The state has received some complaints about construction noise since work began in early June, he said, and one call about odor. The contractor is spraying the waste with a slurry of cement and cardboard paper to reduce odors, ... What kind of precedent is being set? Can I complain about the landfill in my part of town (hypothetically) and have the MPCA bring it up to modern standards? Does this remove any grandfather compliance clause about environmental protection? And really, what's the difference - ethically or scientifically - between cleaning up 3M (and other people's) waste and cleaning up the arsenic floating around the Philips Neighborhood over here? Oh, I know the difference. 3M has tons of money and can afford to spend $8,000,000 to help cleanup. The pesticide company which operated in Philips doesn't exist anymore. and, of course: NIMBY "I don't understand how this could have been a viable solution -- to dig this up, put in a liner, and then put it all back into the ground," said ---, who lives a half-mile east of the landfill. She and others at public meetings advised MPCA officials to truck the trash away to be burned or buried elsewhere. "I don't understand" = MPCA didn't do a good enough job communicating the risk management -- or the person quoted represents people who aren't willing to expend the energy to understand. "I don't understand" just isn't the same as "I don't agree with" or "I do understand and I still think this is a poor choice". I do sympathize with people who don't understand it, and don't have the scientific knowledge to know which questions to ask. If someone doesn't understand, and they're not an environmental toxicologist or hazardous waste controller ... how do we expect them to even be able to question our decisions? Ah, back to my criticism of modern American educational system. Although, I would likely have supported hauling it off to incinerate it. Still, this "make this someone else's problem" just aggravates me. I don't like the fact there's arsenic in the neighborhood near mine - but it's not like the MPCA or EPA is going to pull up the top soil for an entire neighborhood and bury it somewhere else. Until someone figures out how to make money at it. .

Less = more?

Fewer mosquitos!!!! Yea!!! Lower risk of bug-borne infectious diseases? uh, probably No risk? unfortunately, no. I have taken advantage of the opportunity to sit in the front yard in the evenings and simply enjoy the utterly delightful weather we've been having this Summer. It is, quite honestly, the nicest Summer weather I can recall in my adult life; it's definitely the nicest since we've moved here to the Mosquito State.

Mercury increase in Great Lakes

Levels of mercury in pike and walleye increasing from: Minnesota Public Radio

February 17, 2009

St. Paul, Minn. — Mercury levels are increasing in pike and walleye in Minnesota. Minnesota Pollution Control Agency scientist Bruce Monson studied data from the past 25 years.

Monson found that from the 1980s through the mid 1990s mercury levels decreased, but since then they've been on the rise. Monson says that corresponds to an increase in global mercury emissions from 1990 to 1995.

"We're affected by global emissions. 90 percent of the mercury that gets deposited is actually from outside the state." [READ: China]

Minnesota has already greatly reduced its mercury emission levels, and it will cut emissions again by 93 percent by 2025. The state is also working with other states to push the federal government into take action to cut mercury pollution globally.

Review of disaster

Living at this end of the Mississippi, the big disaster is the collapse of the I-35W bridge. A report has finally come out addressing the public health / medical issues. There is a summary of the article in journal Disaster Medicine and Public Health Preparedness covers some highlights of "lessons hopefully learned". Unfortunately, I doubt that the infrastructure maintenance long-term financing has been noticed.
