Um, there are hundreds of Metridium anemones, barnacles, sea stars, nudibranchs, and all the rest that call those pilings home and appear to thrive on them. The fact that at least 4 species of nudibranch that I've seen there personally not only live on them, but lay their eggs and have the young grow to maturity on them, suggests that what we have there is a habitat that is not only good for them, it's extremely conducive to their growth and reproduction. In other words, we already have "healthy marine habitat" there. If it ain't broke, don't fix it.
I've seen a swarm of a dozen or more ratfish chowing down on some huge tubeworms under the dock, and it's the only place that we've ever seen any of the Big Skate, and also where we saw our first juvenile cabezon. A couple of years ago I posted a picture, either on this forum or on the Northwest Diver board, playfully asking "how many rockfish are in this picture?" It was a shot of no less than 10 within about a 3'x3' space, and I took it at the oil dock. This is GOOD habitat. We should do whatever we can to keep an inane government agency from screwing it up.

i'm no marine biologist by any means, but there is significant data that creosote can have serious long-term affects.
humans live in toxic environments, too. and some thrive, even though they're not as healthy as they should be, or may die earlier, or may be passing along birth defects to future generations, etc.
just because it appears healthy, it may not be.

Is it really wise to rip out all that well-used habitat based on a "may not be"? How long has the oil dock been there? Have any adverse effects actually been observed? Seems to me these are questions that should have been explored before making any decisions. This whole thing sounds more like a knee-jerk reaction operation than a serious environmental study and conclusion.

would you want to build your house with creosote soaked logs, dave? even though you might not see any visible sign that your neighbors are affected by their creosote houses, would you live there?
i'm not advocating the removal of these pilings. i'm just pointing out that a proliferation of 3-eyed simpson fish or any other visible symptom are not necessarily the way to tell if something is harmful.
The findings strongly suggest an association between exposure to creosote and the prevalence of hepatic lesions, including neoplasms, in the bottom-dwelling fish,
Some species of fish in the section where sediment contamination was the highest showed a significant increase in the frequency of lens cataracts, fin erosion, and integumental ulceration. Histopathological examination of fish exposed to PAH contaminated sediments revealed a higher prevalence of lesions than in control fish. Liver samples showed a strong positive correlation between cytochrome P450E and sediment PAH. Liver ethoxyresorufin O-deethylase activity showed a similar trend. Several in vitro macrophage function tests (chemotaxis, phagocytosis, and chemiluminescence) showed that integrity of the nonspecific immune response in fish exposed to contaminated sediments was significantly reduced.
The level of DNA adducts in fish from the creosote-contaminated site was 6.8±4.1 nmol mol−1 nucleotides compared to 0.21±0.21 nmol mol−1 nucleotides in fish from the long-distance reference site. The adduct level was also significantly increased compared to adduct levels in fish from the local reference site...In the laboratory, perch were exposed to an organic solvent extract prepared from sediment collected at the creosote-contaminated site or to benzo(a)pyrene (BaP) by oral administration. Perch treated with the extract had adduct patterns very similar to those observed in perch from the contaminated field site.
Hydrophobic DNA adducts were examined in liver, anterior kidney, spleen, and blood of tumor-prone mummichog (Fundulus heterclitus) from the creosote-contaminated Atlantic Wood (AW) site (Elizabeth River, Virginia). DNA adducts eluted in a diagonal radioactive zone, characteristic of polycyclic aromatic hydrocarbon exposure, in all examined tissues of AW fish. Mummichog demonstrated significantly higher levels of DNA adducts in spleen (394±109 nmol adducts/mol nucleotides) than in liver (201±77 nmol adducts/mol nucleotides) or anterior kidney (211±68 nmol adducts/mol nucleotides; P=0.036). The levels of DNA adducts in the pooled blood (pool of four) were 142 nmol adducts/mol nucleotides.
Rainbow trout hepatocytes were exposed for 24 h at 15 °C to several concentrations of the sediment extract. Afterwards, the cells were collected, and cell viability was assayed along with genotoxicity using the nick translation and the alkaline precipitation assays. Results showed that the wharf contained high concentration of polycyclic aromatic hydrocarbons (PAHs), displayed genotoxicity and cytotoxicity to hepatocytes. In addition, PAHs, cytotoxicity and sometimes genotoxicity were detected in all sediment samples and tended to decrease with distance.
Exposure of the mysid shrimp Mysidopsis bahia to water-soluble fractions of creosote-contaminated sediment decreased mysid growth and the proportion of gravid females (82). Exposure to creosote and phenanthrene reduced growth rate and the number of broods, and increased the abortion rate in D. pulex (83). Long-term exposure of the calanoid copepod E. affinis to low concentrations of naphthalenes for 29 days reduced total numbers of nauplii, mean brood size and egg rate production (84). Exposure of the harpacticoid copepod N. affinis to dilute solutions of crude oil reduced brood size (85).

We all want cool sites to dive, but at what cost? I want a clean healthy Puget Sound, not one poisoned for my own selfish interests. Support the cleanup but demand replacement habitat.

Hey, I hope I didn't come off as antagonistic or argumentative. I wasn't intending to be, just trying to figure all this out and find out what it's based on, but I know sometimes I can get a little, um, abrasive. If I did, it wasn't intentional and hope we're cool.
Fishstiq wrote:Creosote pilings? Are you freaking kidding me? People are worried about a couple of pilings leaking into the water? Alright, how about this.....
How many chemicals are leaked from boats, ships, waverunners and the like? How many pollutants find their way to the sound through runoff? How much crap just gets dumped in the sound untreated (Canada, anyone?). And these people are worried about pilings? What's next, adding a "Usage Tax" to my p-valve? Honestly, if you are worried about pollutants in the sound, this approach is like putting a band-aid on an amputated limb. These people just want to "do something", even if their solution is worse than doing nothing at all.

I'm with Ben on this one. Use their momentum agains them and carry them further than they intended by agreeing to the removal and pushing for replacement habitat. The plan shouldn't move forward until both parts of that equasion are accounted for.

The message propagated in other circles of the ccr diving world of staying on the rebreather at all costs while dealing with an emergency is massively problematic
I suspect all or most of us agree. So, how do we go about this? I should be back in Bremerton within the next 3 weeks, I don't have a day job, and I'm prepared to get involved.

Very true. And I have to admit that something needs to be done about the ferry traffic problem in that town, because it's so far beyond ridiculous I'm not even sure there's a word for it. At the same time, it's a shame that they can't come up with a better way to do this. And looking at the layout of that part of the town, I'm not sure that moving the ferry terminal a few feet south (so to speak) is really going to do that much to alleviate the problem. But then, I'm no bureaucrat...
