Noise Pollution maps

There are two maps – one for the unmitigated sound levels from plant operations and another resulting from the “presumed” impact of mitigation. This latter point is important. They do not know the final design of the plant and they have made assumptions about sound transmission from the plant and the mitigation they think they can provide. In their own words, the design is “conceptual.”

The “conceptual” design and mitigation factors result in a noise map that essentially comes in just under the limits permitted. The mitigated noise map clearly indicates that this is based on “conceptualized” mitigation measures.

The unmitigated map indicates there will be 65-75 dBA (decibels) of noise and disturbance within the light mint area on the map. Imagine a constant buzz and drone. A dog barking or an alarm clock is 70 dBA.

The mitigated map indicates there will be 35-40 dBA (decibels) of noise and disturbance if you are anywhere within the light yellow area on the map.

This noise measurements are based on what the power plant will produce. It does not include freeway or ambient noise from other sources. You need to add these other noises for an accumulative effect.

Power sources and transmission lines

“Such proposed power sources and their transmission lines should be built 1000 ft minimum from any places there may be pregnant women, small children, schools, housing with children or potential high density population centers.

I supervised a team that did 2 years of non-ionizing radiation hazard (RADHAZ) surveys. It included power line emission measurements. We only made intensity measurements but were told to avoid drawing conclusions because only highly qualified and education certified “experts” can do that.

In my presentations I offered caution as my best advice. In this case, locate such power plants out in the middle of a nowhere so ugly and desolate that developers will have no interest raising housing suburbs near it. If Santee fits that description then it is a good candidate for such a project.

Caution is called for because our experts and vested interest parties waiver on conclusive hazard findings. One knowledgeable expert once told me ‘that electrical power in the modern world is such a necessity that we must live with all its unknown acceptable risks regardless of what they may eventually turn out to be.’ Fast reproducing and dividing living cells in all living things appear to have some degree of vulnerability when in close proximity to such potential RADHAZ power sources as electrical equipment.

Few dare to take a stand on this subject or even seek funding to conduct effective research studies. Such a controversial subject can lead to unknown future results and expenses.”
