Overview of Formosa Drainage Study

annika

This supplementary legal document describes recommendations for storm- and waste-water management improvements for the Formosa petrochemical plant in Calhoun County, Texas. The text is a fairly standard drainage assessment. The author describes non-trivial discharge of pollutants out of the plant’s outfalls, which drain into local waters, and the inability of the plant’s systems to prevent flooding from even small storms. For some context on this, it is pretty standard to design a stormwater system to be able to drain the 100-year storm (that is, the storm with a 1% or less chance of occurring in any given year). Formosa’s Texas plant demonstrated the inability to convey even the 2-year storm.

Formosa Drainage Study

Emphases are mine:

Problem areas were identified based on the results from the outfall drainage studies provided by Formosa. Thus, all the results in the OPCC rely on those studies, uncertainities associated with those studies, and the assumptions made for those studies, some of which may or may not be appropriate as I pointed out in Supplement #2 [Page 4]” (3)

“The proposed improvements assume that the conveyance capacity of the problem areas is increased 100%, which would be able to handle twice as much flow that it currently does. The results from the Drainage Study are not conclusive as to what storm event Formosa’s system currently is capable of conveying. The report does mention that the system is not capable of conveying the 2-year storm, and “sometimes” not even the 1-year storm event. (3)

“A 45% contingency is applied to the OPCC due to the uncertainties associated with underground utilities, likelihood of existence of low road crossings and need to replace those, groundwater impacts, other unknowns, and additional costs associated with engineering, etc. 45% is reasonable and in line with industry practices in my experience, especially given the large amount of unknown information available.” (4) 

“My opinion from my July 9, 2018 report that “there have been and are still pellets and/or plastic materials discharges above trace amounts through Outfall 001” is further supported by the deposition testimony of Lisa Vitale, as representative for Freese & Nichols, Inc, that she and her colleagues have seen floating white pellets or small plastic pieces in Lavaca Bay and in the area near outfall 001 as part of her work on the receiving water monitoring program for Formosa’s TPDES permit...Ms. Vitale also testified that she told John Hyak of Formosa about these sightings as well as has sent him water samples with the pellets about five or six times, including at least one time prior to 2010. This, along with the June 2010 EPA Report I cited in my July Report, demonstrates to me that Formosa was aware of problems related to discharges of plastics from its facility since at least in 2010.” (6)

 

UN Scientific Committee on Effects of Atomic Radiation, Fukushima Report

Sara.Till

The report encompasses reports on the proceedings of the UN Scientific Comittee during its 60th session, May 2013. The UN report presents an unbiased plethora of data surmising Fukushima radiation exposure to both human an biological life. It primarily focuses on 2 reports detailing aspects of radiation exposure during the 2011 nuclear accident. The first report gives estimated levels of radiation experienced by individuals and non-human biota. Human individuals estimates are based on age and ongoing proximity to the accident. Evacuated adult citizens had an estimated exposure <10 mSv, while workers experienced doses >10mSv, with the highest exposure  an estimated 100 mSv. It places these values within the context of lifelong anticipated exposure and international expected exposures. This first report also briefly discusses effects beyond radiation, including the adverse outcomes thousands faced by evacuating. The second report concentrates on radiation exposure of children during the accident. While it concludes longer epidemological studies are needed to accurately assess the prevailing biolgogical effects, several important facts are highlighted. At a given radiation dose, children are more at risk of tumor induction than adults. In addition to this increased radiosensitivity (partially due to physical factors such as size), children also demonstrate increased prevalence of several cancers. These include leaukemia, brain, and thyroid cancers, all of which show radiosensitivity. The report also suggests narrowing the scope of inquiry, as radiation-induced cancers can be influenced by factors such as age and gender.

The report was written on the behalf of the United Nations Scientific Committee on the Effects of Atomic Radiation as a summary of their sixtieth session. The summary was written to be read to the United Nations General Assembly. The scientific data reported was collected by independent teams working on behalf of the Committee.

This report is comprised of several parts, beginning with an introduction. The report describes radiation exposure and effects that have been linked to the Fukushima disaster. Then it outlines future goals of increased awareness of the risks of nuclear disasters and the effects of radiation exposure as well as the need for a network of experts capable of sharing knowledge and expertise when needed. Finally the report mentions further studies being completed concerning the effect of radiation on children.

This report addresses the long term effects of a nuclear disaster and the potential health risks of radiation. The findings presented in this report are important when considering the long term effects of a disaster and the clean-up aspects of responding to a disaster that may continue for months or even years following the initial event. The Committee’s plan for the 2014-2019 period includes consideration of a network of experts to share information amongst the scientific community as a method of increasing awareness of and preparation for potential nuclear industry disasters.
