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 main findings of the article are that the relationship between natural disasters and communicable diseases is not as much due to dead bodies or high trauma as it is to population displacement and a lack of preparredness of the local governing body for the disaster and the crowding of survivors that follows a disaster as this

1: Crowding is shown to be common in displaced populations, and local overpopulation/crowding often facillitates the transmittion of disease

2: Natural disasters that do not cause a displacement of a population are rarely associated with disease outbreaks

3: There is little or no evidence that dead bodies, as some believe, pose a epidemic risk for a population of survivors after a disaster has struck

"The risk for commuicable disease transmission after disasters is associated primarily with the size and characteristics of the population displaced, specifically the proximity of safe water adn functioning latrines, the nutritional status of the displaced population, the level of immunuty to vaccine-preventable diseases..., and the access to healthcare services"

"...natural disasters (regardless of type) that do not result in population displacement are rarely associated with outbreaks"

"When death is directly due to the natural disaster, human remains do not pose a rise for outbreaks"

Emergency response is addressed in a broad sense of the major risk factors associated with a natural disaster and epidemics. The main points they make are that preparedness, with a focus on availability of safe water and primary healthcare services, along with surveillance for the beginnings of an epidemic, are necessessay for a strong response to a disaster situation

This article has been referenced in a wide variety of emergency medicine journal articles, ranging from flood protocols, use of cell phones in disaster enviroments, earthquakes and medical complications, to the costs of disaster consequences. Many of the articles referencing this paper appear to go into greater depth for some of the epidemics and diseases that were touched on in the research article. These include hepatitis E, Leptospirosis, cholera, and tetanus.

The object of the study is the evidence in an increase of various types of epidemics (cholera, malaria, menigitis, tetnus, etc) due to displacement of a populatoin from a natural diasaster. Examples of natural disasters discussed include- hurricanes, cyclones, earthquakes and flooding. Despite popular belief (and scientific evidence) deaths due to natural diasters do not spread diasese; unless cause of widespread infection is due to contaminated water sources, malnutrition, residing in a third world country,access to healthcare and adequate bathroom facilities. These points are supported through statistics from the past twenty or more years.
