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)

The study is in the Annual Review of Public Health. This is just one journal out of many Annual Reviews; the studies/ topics published are solely related to public health, such as epidemiology, biostatistics, and health services. Health professionals use the Annual Review to look at major articles in Public Health, for research, and for teaching.

The object focused in this epidemiological study is the incarcerated group. Whereas the study has focused on the reason why certain group of people incarcerated and therefore increase the amount of drug uses and decrease the health quality. The formation of the incarcerated community has spotted on analyzing few areas that include human races, relevant family incomes and the facilities with health care in both prisons and jails.

The final edited version has published via Annual Reviews of Public Health.

“The Annual Review of Public Health, in publication since 1980, covers significant developments in the field of Public Health, including key developments in epidemiology and biostatistics, environmental and occupational health, issues related to social environment and behavior, health services, and public health practice.” [http://www.annualreviews.org/journal/publhealth]

The journal can help the health professionals by exploring not only contents in the sub-sections of Public Health but further more explore other detailed topics with other journal sections such as Medicine, Nutrition etc.

“The mission of Annual Reviews is to provide systematic, periodic examinations of scholarly advances in a number of fields of science through critical authoritative reviews. The comprehensive critical review not only summarizes a topic but also roots out errors of fact or concept and provokes discussion that will lead to new research activity. The critical review is an essential part of the scientific method.” [http://www.annualreviews.org/page/about/our-mission-and-our-founder]

The main method has used in this study by review the health profiles of the incarcerated group. Via this method, the basic background information can be gather and analyze with categorized people into different groups such age, races, gender etc. Furthermore, with group analyze some conclusion can be made to execute a possible solution to decrease the incarcerated people in order to improve health conditions. The health records are also useful to make prediction trend of the future environment, even though the conclusion from the prediction is the situation would not change as much as general publics and authorities expected.

By reviewing health profiles of the incarcerated group to study this issue, personally would say it is quite a quick and reliable way but not quite sure on the innovation level of this kind of methodology. Another issue with method is the possibility on the violation of personal information and ethical controversy.
