“This is the current status of the ongoing EIR process on suction dredging in California.”

This was a section of Dave’s March newsletter, which can be found here.

Progress on EIR:

The one thing that will allow us all the put our suction dredges back in the California waterways is completion of the EIR!

It is so important that the job must be done right. This is because anti-mining activists are also attacking us within the ongoing EIR process. They are trying to show that suction dredging creates really bad impacts, when it actually does not.

During the past several weeks, DFG has organized several formal meetings where interested parties (concerning suction dredging) have been able to meet and discuss the various issues which need to be worked out. The third and final of these meetings took place on 11 March. The New 49’ers, along with several other organizations within our industry, has very qualified representatives at these meetings. Anti-mining activists are also well represented in the process. There are specialists involved which represent all sides of the issues.

Through the discussions and other public input so far concerning suction dredging, the subject of mercury appears to be one of the most important and contentious issues so far.

While the authorities have proven that normal suction dredges recover 98% of the mercury that is sucked up into our sluice boxes, anti-mining activists are taking strong issue with the potential loss of 2% becoming a water quality violation. Yes; I know; you would think that the various government agencies and environmental organizations would be happy with a 98% rate of mercury recovery at no cost to the taxpayers. But nearly all of the focus remains upon the potential 2% loss of mercury which would have already been in the stream or river in the first place!

I personally have been involved with several federal projects during the past few years to help figure out how to recover 100% of the mercury (zero loss) when trying to remove mercury from submerged waste sites where hundreds or thousands of pounds of mercury were lost from historical gold mines.

During 2008, we developed a closed circuit dredging devise that is able to trap all of the sediments and all of the water used to create suction-power at the nozzle. We tested the system with assistance from the Bureau of Land Management and U.S. Geological Service, actually proving that by recirculating the same water over and over gain to dredge contaminated waste material (from the South Yuba River in California), we were able to capture and concentrate 100% of the finest particles of mercury that would presumably be lost from a normal suction dredge. The project was quite successful!

However, anti-mining activists have now taken the mercury concentration levels within our closed system (which was used for hours within a known waste site) to try and prove their case that suction dredgers are discharging high levels of mercury into active waterways all across the State. It never ceases to amaze me how low our enemies will stoop to try and get rid of us! Here, we were doing a really good thing by developing equipment that will help clean up serious waste sites. And anti-mining activists are trying to misuse the data to create a negative reflection upon all suction dredgers.

So I have personally invested quite a lot of time in trying to straighten this all out within the ongoing EIR process concerning normal dredging activity outside of hazardous waste sites. You can find my work on this subject on our web site. I highly recommend this as excellent reading if you want to get a feel for what we are really up against.
