Pdf doc...Query [ caltrans 2012 herbicide reduction]<br />Pdf document - http://www.dot.ca.gov/hq/env/stormwater/annual_report/curent_ar.pdf<br />"Caltrans decreased potential pollutant loadings to the storm drain system and local waterways as part of its landscaping program. Caltrans applied 206,773 pounds of herbicide active ingredient, reducing the total amount of herbicides applied by about 39% during the fiscal year 2010-2011."<br />Not confirmed elsewhere. No databases located (but I believe exist).<br />As for dangerous or not I found reports on both sides. Caltrans has reduced usage which in itself at least acknowledges the need to reduce. They are exploring other options to deal with roadside vegetation other than chemicals. This issue is up for debate. <br />Rosemary Mhttps://www.blogger.com/profile/12291661159622665464noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-36825446543635013252013-03-13T16:57:42.778-07:002013-03-13T16:57:42.778-07:00Niebylski this was for all rights of ways in Calif...Niebylski this was for all rights of ways in California which it said also included railway rights of way.

From there I followed their link to California Pesticide Information Portal (CalPIP, http://calpip.cdpr.ca.gov) to generate a query.<br /><br />My search criteria:<br />Site/Crop: RIGHTS OF WAY<br />defaulted to Year: 2010<br /><br />A huge list was yielded. Saved it into a tablesheet and calculated some totals here: https://docs.google.com/spreadsheet/ccc?key=0AnbMB3yUFCzwdG9na1BjemY3Z3FObnBxMGRXbmNrdmc&usp=sharing<br /><br />Results:<br />In 2010 alone, 2036967,354 pounds of product were sprayed, of which 935732,81 of chemicals (don't know exactly if this means that the rest are non-active elements). Of those, ROUNDUP PRO CONCENTRATE HERBICIDE is almost 1/3, with 774861,7333 and 388980,5901 of chemicals.<br /><br />No idea how toxic those are and it seems to me that, unless others have already studied the problem and published it (not unlikely, in fact), it will be a very long research and calculation.Luís Miguel Viterbohttps://www.blogger.com/profile/13198394145108636883noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-82323612606589454572013-03-13T12:52:31.423-07:002013-03-13T12:52:31.423-07:00What do I know?

Not as many as Texas ( [Highway miles by state] first result: http://www.census.gov/compendia/statab/2012/tables/12s1089.pdf ), but probably more that require vegetation control. But still, if the numbers do hold together, then 6.5% is a lot for a single state to consume.

Did a search caltrans roadside herbicide which led us to this site: http://www.dot.ca.gov/hq/LandArch/research/weeds_and_pests.htm<br />From this site we learned that Caltrans sprays the roadside to prevent weeds, control fires, eliminate nonnative species of vegetation and to save money by not having to mow. We went back to our search results and found the site http://coastroad.me/2010/04/13/1537/ Reading this site we found that the names of the chemical products used and the problems they caused- Roundup, Aquamaster, Milestone and Garlon. It also gave us the name of the dept that regulates pesticide use- Department of Pesticide Regulation. We went to their website <br />http://www.cdpr.ca.gov/ and from there we found a link for pesticide use stats. We clicked on 2010 the latest year available and found a link for top 100 sites and found that for rights of way (this does include alongside railroad tracks so it isn't just roadside but think it is close enough) the amount of pesticide/herbicide used is 3,366,150 pounds! We had found one site that stated that these herbicides caused prostrate and breast cancer but felt it may have been a slightly biased site so we then looked up the toxicity of Roundup. We found several authoritative articles the first being from Scientific American http://www.scientificamerican.com/article.cfm?id=weed-whacking-herbicide-p that discussed the toxicity to humans from the various ingredients in RoundUp. <br />This search was fun and interesting and was especially relevant as a topic in school setting. This one took us less than 30 mins. to find. Again I did this search with my colleague Anne.

The non-profit environmental group Californians for Alternatives to Toxics (CATs), based in Arcata, has worked on issues involving the use of pesticides -- including their use in forestry, vitriculture, roadside maintenance, and in schools -- for 20 years. Their lobbying to reduce herbicide use led Caltrans to announce a goal to achieve an 80 percent reduction in the amount of statewide herbicide spraying by the year 2012 (in terms of pounds of active ingredients) from 1992 levels. Recently Caltrans announced it met an earlier goal of reducing herbicide use by 50 percent between 1992 and 2002."<br /><br />***<br /><br />Here's a list (2010) of approved herbicides by Caltrans, in orange the dismissed ones, among them are Diuron and Oryzalin. Couldn't find any report like the 1999 study by CAT relative to recent years, btw. macahttps://www.blogger.com/profile/03746508150717638886noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-6687883140711715382013-03-13T08:31:40.334-07:002013-03-13T08:31:40.334-07:00Living in the UK I have no idea of how US state go...Living in the UK I have no idea of how US state government and departments are organised but I decided to jump in at the deep end and include site:ca.gov in the search. I also included a numeric range 2009..2013 not knowing how up to date the statistics would be. My search strategy was:<br /><br />site:ca.gov roadside herbicide use pounds 2009..2013<br /><br />Top of the list was what looked like an unpromising PDF "Caltrans Stormwater Management Program Annual Report" at http://www.dot.ca.gov/hq/env/stormwater/annual_report/curent_ar.pdf but the summary in the results suggested it was relevant.<br /><br />It wasn't immediately obvious from the bookmarks that the report covered herbicide use so I used Ctrl F to look for herbicide within the document. There is a section on herbicide use under Maintenance. <br /><br />On page 36 it says "Approximately 207,000 pounds of active ingredient were used to treat an estimated 57,727 acres in Caltrans’ Integrated Vegetation Management program during the fiscal year 2010-2011". I have only looked at this section out of context so I need to go back and review the whole document to make sure it is saying what I think it is. <br /><br />Taken about 7-8 mins in all so far. <br />Karen Blakemanhttps://www.blogger.com/profile/16177433044316910079noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-89883039013171366042013-03-13T08:00:24.732-07:002013-03-13T08:00:24.732-07:00Interesting... except this is from 1999.
