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 information of the article was collected by investigating several news agencies. For example, a team of journalists from the Guardian and health works went to the distant village of Guinea to cross the words about Ebola. From the words of the Guinea village chief, journalists from other news agencies are also known.

The article has reveal the trust issue (crisis) dealing between the local publics and the health department workers on the spread of Ebola (and anyone that assist with the work of spreading the awareness of Ebola). This issue is revealed via the several violence acts happened in the area. These cases are reported with briefs of scenes and relevant data.

In this article, the main agencies been depicted are the local publics and the health centers. From the reports, Guinea medical centers and aid works are the main targets that received violence acts and harassments from the general publics. Whereas the publics have the perception that aid workers such as doctors and nurses are the transporters of the virus within the local communities.

  1. With the lack of understanding of new disease (in this case, Ebola for the villagers), the trust crisis is easily raised up between publics and aid workers due to the fear of unknown things.
  2. The number of death been announced can violate the faith that publics put into the aid workers. Acts of violence are the fears from the publics.
  3. There is a lack of medical education in the area like Western African, Ebola has been there for three times since 1970s, and the publics still not having the correct perception on the disease awareness.

In terms of precaution regarding air pollution, the article talks about making good choices of transportation which means to walk or bike or take public transportation whenever feasible; choosing cars that have better mileage per gallon or electric cars; buying food locally grown rather than food from other places in order to reduce air pollution.
