Here are the comments you requested. cheers, Andy From: <email address removed> Subject: bute proposal comment Date: February 18, 2009 11:59:45 PM PST (CA) To: [email protected] Cc: [email protected] February 18, 2009 Marie-France Therrien Panel Manager, Canadian Environmental Assessment Agency 160 Elgin Street, 22nd Floor, Ottawa, ON K1A 0H3 Comment on Draft Terms of Reference for establishing a federal review panel for the proposed Bute Inlet Hydroelectric Project From: Andy Sinats Director BCEN ED Society Targeting the Overuse of Pesticides Thank you the opportunity to comment on the Draft Terms of Reference for establishing a federal review panel for the proposed Bute Inlet Hydroelectric and the draft federal-provincial environmental impact statement guidelines. I am a concerned citizen of British Columbia. The cat is out of the bag. The president of the proponent Plutonic power's Bruce Ripley stated a week ago, "For my government in British Columbia, I think that they are making a big mistake by precluding nuclear." This project for whose ecological impact these comments are being solicited cannot stand on its own and is an investment scam. Not only can this project not do what it purports to do, provide power in a reliable and consistent fashion, but like the pyramid scheme that it is, it require s innumerable add-ons, some of the totally uncertain. a) it requires yet another transmission line for the Bute project, parallel to one already at Toba Inlet, because Plutonic for sees its own need poorly b) it requires rain at the right time of year in a quasi-predictable amount and at present there are droughts in Mexico, California, Argentina, Australia, the southern US, China and I could go on. Planners here have been very slow in acknowledging any changes in warming or the economy and particularly the climate on which this project depends. c) it requires flow thru of four billion dollars in a time of economic uncertainty when all mega projects are tanking and infrastructure in the tar sands for one example is being abandoned to rust on the ground. When the cash from GE stops, all this prattle about PPPs will also be abandoned and the tax payer of BC will again be the bailer out of last resort just as the Olympic Village in Vancouver, the entire auto industry, and half the banks. d) it requires Nuclear power because Mr Ripley has himself acknowledged his project needs a prop. Therefore the terms of reference to review this projects feasibility have to reference, GE's future financial viability, world climactic uncertainty, the impact or additional transmission line corridors and the damage to the wilderness they entail;and the potential impact of industries that will be pulled along by this project such as nuclear which I remind the panel is under a moratorium in British Columbia. As to the ecological impact, what this project suffers from is an untenable distance from its consumer. This untenable distance between supply and demand is unsupportable except by a fracturing of the entire wilderness by tentacles and webs of transmission line corridors, bridges, roads, and structures all build with toxic materials. file://S:\Panels\Bute Inlet\Public Comments\bute proposal comment.htm 2/26/2009 Page 2 of 3 Recent research by Nathanael Scholz of the NOAA, and Dr. Keith Tierney of the University of Windsor has proven beyond reasonable doubt that salmon are adversely impacted by the copper, chromium, and arsenic compounds in pressure treated wood used in bridges, poles, and wooden structures. Although runoff may not constitute a lethal dose for salmon and other fish species, in fact a sub-lethal dose is all it takes to permanently impair the olfactory ability of salmon to evade predators, reproduce, and find their spawning river. It is obvious that industrialization of the wilderness entails considerable use of toxic materials. In particular the electric grid currently maintained by BC Hydro and BC Transmission consists of 1,100,000 poles treated with CCA. It is expected that run of the river projects and alternate energy projects that require transmission corridors to connect to this existing grid will have to apply for Pest Management Permits, and it is unlikely that the standards currently in place regarding NTZ's or No Treatment Zones, will be any more rigorous than the thoroughly insufficient setbacks in use today. It is only very recently that research has revealed that pulses in copper due to rain events particularly in the vicinity of road crossings at streams and rivers contribute to sub-lethal impairment of the olfactory ability of all vertebrates and have negative implications prejudicial to the entire web of life in the affected areas. Please see the attached studies by Scholz, Baldwin, et al. Other studies have shown Roundup and other glysophosates (Tierney, et al) typical of the herbicides used for weed control and maintenance of right of way corridors for heli-landing pads, railway beds, transmission line corridors, and other similar uses is also very prejudicial to salmon survival. In February 2009, First Nations fisherman report the salmon runs have never in their experience been as low as they are right now. Each of the two lower mainland dumps has at present 400-500 eagles, never seen there in such numbers, searching thru garbage because there are no salmon in our rivers. The entire web of life in British Columbia, without exaggeration, is at risk, Dr. Scholz, whose study is attached and who has studied copper leaching into the aquatic environment and its effect of migratory salmonids states: "Increasing runoff in areas of growing urban and rural development may explain why salmon are disappearing from streams throughout the West." Thank you for your consideration of these comments. I appreciate your attention to the concerns and recommendations expressed here, as we seek to reduce the planet’s toxic load of persistent bioaccumulative toxic chemical, and chemicals with other long-term toxic effects on health and the environment, to which road building, transmission lines, and the industrialization which accompanies IPP's, and logging is a major and unnecessary contributor. sincerely, Andy Sinats addendum: St. Francis--patron saint of ecology.

In vivo ®eld potential recordings from the olfactory epithelium (electro-olfactograms) were used to measure the impacts of copper on the responses of olfactory receptor neurons to natural odorants (L-serine and taurocholic acid) and an odorant mixture (L-arginine, L-aspartic acid, L-leucine, and L-serine) over a range of stimulus concentrations. Increases in copper impaired the neurophysiological response to all odorants within 10 min of exposure. The inhibitory effects of copper (1.0±20.0 mg/L) were dose- dependent and they were not in¯uenced by water hardness. Toxicity thresholds for the different receptor pathways were determined by using the benchmark dose method and found to be similar (a 2.3±3.0 mg/L increase in total dissolved copper over background). Collectively, examination of these data indicates that copper is broadly toxic to the salmon olfactory nervous system.

In this epoch it is human that is the single highest good (summum bonum), and all other values will gain their significance based on their scope of relations with the man. ^ is work’s guiding principle is the concern over the future of human species, which, according to its author is threatened not so much by degradation of nature, as by degradation of social environment. Upon reading that paper one can conclude that men cease to control their artifacts, especially those of science and technology; they are no longer capable of accomplishing their goals in a simple, direct manner. More and more commonly people feel lost and alienated from reality in they live in. It is as if we were to learn anew how to handle everyday life’s situations.

  • Waters Are More Polluted Than Tests Say: Standard

A: Currently I’m a post-doctoral scholar at Dr Richard Connon’s lab at WATERS ARE MORE POLLUTED the Anatomy, Physiology and Cell Biology Dept. at The University of California Davis. I got my PHD degree from the Technical University of Munich (TUM) in Germany, but I conducted all my research for my previous studies at the University of California Davis, in collaboration THAN TESTS SAY: with TUM. I have been in the US since 2010, and I’ve been working mainly on the effects of pesticide mixtures on the aquatic environment. My main focus currently is on the invertebrate species STANDARD TOXICITY that all fish and higher trophic organisms need - I am convinced that if we know what is going on at the lower end of the food chain that we can help all the other organisms throughout the chain. ANALYSES COME UP SHORT Before I came to the US I earned my Masters degree at TUM in Ecotoxicology, Limnology and Ecology, and I’d also already studied the effects of pesticides on invertebrate communities. Currently I’m looking at contaminants of all different kinds –insecticides, herbicides, AN INTERVIEW WITH DR. SIMONE HASENBEIN pharmaceuticals – and what their effects are on invertebrate species, as well as algae species, in lab toxicity studies and field studies. We recently found that contaminants are no longer found in such high concentrations out in the field so as to cause mortality, so we shifted our focus to sublethal end points.

    ABSTRACT Advancing an Understanding of Ecological Risk Assessment Approaches for Ionizable Contaminants in Aquatic Systems. Theodore W. Valenti Jr., Ph.D. Committee Chairperson: Bryan W. Brooks, Ph.D. Freshwater is increasingly becoming a finite resource in many regions of the world. Gaps between estimated water supply and demand continue to narrow and the prospects of acquiring additional sources of freshwater remain limited. Furthermore, economically efficient water resource management practices are perplexed by increasing urbanization and changing land-use in semi-arid regions. Although repeated use of water is a practical and effective means for easing strain on water supplies, there is concern that unnecessary contamination may diminish future value of this important resource. Some surface waters in semi-arid regions of the U.S. are effluent-dominated as flow is comprised of >90% treated wastewater. Ionizable compounds are chemicals often associated with urban development and examples include pharmaceuticals, agrochemicals, natural toxins, and other common contaminants (e.g. ammonia). Because continued population growth and urbanization are likely to increase contaminant release and alter dilution capacity of receiving systems, it is important that best management approaches are developed at the watershed scale to limit water quality degradation associated with ionizable compounds. Current methods for prospective and retrospective ecological risk assessments of ionizable compounds seldom consider site-specific conditions during the analysis of effects of phase. Ionization state is largely controlled by the acid/base dissociation constant (pKa) and pH of the solution where a compound resides. Stream water quality can therefore influence ionization state, which is important because the unionized forms a more lipophilic and have a greater propensity to cross cellular membranes.

Yet, these expectations assume that populations in different regions are equally susceptible to the effects of warming. This is unlikely to be the case. Here, we develop a series of predictive models for physiological thermal tolerances in ants based on current and future climates. We found that tropical ants have lower warming tolerances, a metric of susceptibility to climate warming, than temperate ants despite greater increases in temperature at higher latitudes. Using climatic, ecological and phylogenetic data, we refine our predictions of which ants (across all regions) were most susceptible to climate warming. We found that ants occupying warmer and more mesic forested habitats at lower elevations are the most physiologically susceptible to deleterious effects of climate warming. Phylogenetic history was also a strong indicator of physiological suscepti- bility.

However, behaviors can also be impaired by environmental contaminants. Links between changes in brain biochemistry and behavior have been made, and understanding these relationships could increase the utility of these endpoints in ecological risk assessments.
