The Sierra Club Yolano Group, together with its local partner, Yolo Land and Water Defense, is desperately trying to stop a massive new sand and gravel open-pit mining operation. This proposed project will forever destroy 300 acres of productive prime farmland just off of Cache Creek a few miles west of Woodland. Almost in the city's backyard, this huge new surface mine will leave behind a wasteland of methyl mercury contaminated impoundment ponds, no guarantees of successful farmland reclamation, potentially serious decreases in local groundwater levels, and greenhouse gas and priority pollutant emissions far greater than estimated (see below for more detailed information about the project's environmental shortcomings).
Our lawsuit challenges improper mining project approvals. Over vigorous objections about the lack of appropriate environmental protections as required under California law, this project was recently approved by the Yolo County Supervisors when they certified a defective Environmental Impact Report (EIR) and awarded lucrative 30-year sweetheart mining rights to Teichert Mining. The company is a subsidiary of a billion-dollar mining and construction behemoth. To stop this ill-advised and destructive project unless necessary protections are put in place, the Sierra Club with our partners recently sued Yolo County and Teichert Mining to rescind certification of the EIR and project approvals.
The Sierra Club and a number of members of both organizations have already made very substantial contributions, but we urgently need to raise $12,000 more to continue this lawsuit all the way through trial. Please help us force Teichert Mining to act responsibly so that our children and future Yolo County generations can enjoy unpolluted habitat, productive agricultural land, safe and reliable access to good quality water, and clean, breathable air.

I have aural nerve damage in one ear and so have had to, out of necessity, learn how sound affects the human body. Loud sounds can cause me splitting headaches emanating from the inside of the ear, severe ringing in the ears, internal ear pressure, disorientation, burning, aural misinterpretations, etc. Sound frequency, duration, distance, peak-volume and distortion all factor into the severity of an 'event' as I have come to know them.
Though dependent on particular circumstances, in general shorter bursts of loud sounds are more damaging than longer duration of softer sounds. That is why going with some sort of 'averaging' system would be a tragic mistake. This would ignore the very real damage done by peak sounds. My world-renowned ear doctor from Stanford Ear Clinic would back me up on this. He has coached me on how to live with my condition, which is not treatable.
My ear doctor explains that there is a 'threshold' level at which the noise becomes damaging to hearing (in my case, the threshold is much lower than those with a healthy ear). The PEAK noise is almost always the problem. Therefore, changing the city noise ordinance to consider some AVERAGE measurement as the standard is not only unwise, it is INSANE.
To give an example of how unwise this is, an example everyone can understand – consider train horns. A train horn — at 100' in front of the horn — ranges from 96 to 110 db. Even at the low end this is painfully loud, and on the high end can cause ear damage in just a few seconds. But, if you averaged the railroad noise around the tracks over a period of hours, it would show very low AVERAGE noise as over time there are few trains. The PEAK noise is when the damage is done; AVERAGING OVER TIME would FAIL to CATCH the DAMAGING peak sounds.
While I am more bothered by sound than those with healthy hearing, ear disease is rampant and hugely under-diagnosed in this country. There are many people with my condition and many other hearing diseases who are intolerant of various sound conditions. This is not just about an annoyance, it is at times debilitating.
Another thing to consider is that those close to a noise source suffer from the exposure repeatedly and over time. Those adjacent to noise sources are the people who must be considered paramount and above all else. Let's say a nightclub with sub-woofers goes in next door to someone's house. But ON AVERAGE less than 1% of the people in town even hear the noise. The standard must be on how the noise effects those adjacent, not on the fact that 99% of Davis voters never hear it. Another abominable use of 'average' exposure.
I urge the commission, the City, and the Council to retain current noise-ordinance formulas and standards, and reject any attempt to change the noise ordinance to be more allowing of harmful peak noise exposures.
Sincerely,
Alan C. Miller, District 3
