WHICH WAY THE WIND BLOWS
“Strontium-90 is considered to be the most hazardous bone-seeking element created in the fission of uranium or plutonium because of its long half-life of 28 years and because it resembles calcium so closely,” wrote Dr. Ernest Sternglass in 2003. Sternglass is the Professor Emeritus of Radiological Physics at the University of Pittsburgh Medical School, and has written numerous articles on low-level radiation. In 1963, he was invited to testify before the congressional Joint Committee on Atomic Energy, explaining how the exponential increase in strontium-90 in baby teeth caused by atomic bomb-test fallout was associated with increased childhood leukemia.
Radioactivity has been detected in astronomical amounts on the Santa Susana Field Laboratory, fueling concerns that it might be migrating onto the Runkle Canyon property. One of SSFL’s experimental reactors suffered a partial meltdown in 1959 with a third of the core melting and radioactive gases being vented into the atmosphere. Two other reactors suffered damage in 1964 and 1969. In 1989, the Department of Energy found widespread radioactive and chemical contamination at the site, and a cleanup program commenced which ultimately will cost approximately a quarter of a billion dollars.
Sailing Through
City planners acknowledge that there may be a few problems with the EIR’s assessment of potential radioactive contamination at the site but toss it off as simply a matter of grammar. “You know, that sentence could have been written a little bit better, I’ll have to say that,” says Lauren Funaiole, senior environmental planner for the city of Simi Valley. “It could have been broken up into two [sentences] and it would have been a little bit clearer. The strontium-90 was above normal background levels, however, that study did find that it did not pose a significant health risk.”
“It’s a very thorough EIR,” says city planning director Peter Lyons. “We had many, many public meetings. The project received a lot of input. Some of the major concerns of this project were traffic and visibility from the valley floor. The issue of strontium-90 was not something that people were concerned with.”
Ignorantly or deliberately, the city of Simi Valley’s subcontractor charged with evaluating the EIR, Agoura Hills-based Impact Sciences, didn’t include the comprehensive data supplied by QST or Foster Wheeler in the EIR, though Foster Wheeler’s dismissive conclusion about Runkle’s high Sr-90 soil readings was included but not attributed. “The Miller Brooks study of 2003 was truly the report that we used, and Impact Sciences used, to do the EIR,” says Lyon.
Miller Brooks took six soil samples in the area that the Runkle Canyon residences are to be built and sent them to Casper, Wyoming-based Energy Laboratories. That lab tested the samples employing techniques that only had detection sensitivity of 2.0 to 10 pCi/g, or nine to 43 times too insensitive to even ascertain the EPA’s preliminary remediation goal for Sr-90. Nonetheless, readings of 2.1 and 2.2 pCi/g were detected, nearly ten times over the EPA goal. Regardless, Miller Brooks calculated the danger from the readings as “0.77 in a million,” using mysterious computations not attributed to any EPA method.
This finding is particularly disturbing because the potential is high, say scientists, for offsite transport of strontium-90 in impacted dust. Airborne Sr-90 could be in particles so tiny that several thousand of them could fit on the period at the end of this sentence.
The draft EIR (DEIR), which makes up a large section of the Final EIR, seems unclear as to just how seriously to take this dust. “No fugitive dust control for the 25 percent of the development area actively being graded is being assumed,” reads the document, before later stating, “Therefore, operational-related air quality impact would remain significant and unavoidable, even with the implementation of all feasible mitigation.” Still, no mitigation was required.
During the day, the average winds blow eight miles per hour from the northwest to the southeast over the Santa Susana hills and into the western part of the San Fernando Valley. At night, and during Santa Ana winds, the wind direction and speed changes and could carry this dust into Simi Valley. “While much of the airborne dust … would settle on or near the area being graded, smaller particles would remain in the atmosphere, increasing particulate levels within and adjacent to the graded area,” the EIR states.
“So we did consider it an impact deserving enough and significant enough to require mitigation such as the dust mitigation plan with water,” says Lyons. “In the analyzing of the project, maybe there were some statements there that it wasn’t significant. In the end, in the Final EIR, we determined that it was significant and that it had to be mitigated.”
A conservative estimate of the amount of dust made airborne, not including the golf course construction, is around one hundred tons of particulate matter launched into the air.
The fallout of this dust is just something that the Simi and San Fernando valleys will apparently have to live with. Contesting the convoluted, confusing, and counter-factual Runkle Canyon EIR is a mute point – the public and environmental activists alike have no legal recourse. “There is a very short window of opportunity to file a CEQA (California Environmental Quality Act) lawsuit,” says Dr. Joe Lyou of the California Environmental Rights Alliance, a public interest organization. “If the time to file has passed, you’re screwed.”
