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)

In the article, the authors used data from the 2011-2015 American Community 5-Year Estimates by the U.S. Census, 2010 U.S Census, and George C. Galster, “The Mechanism(s) of Neighborhood Effects: Theory, Evidence, and Policy Implications.”. They looked at data follwing children under 18,  and followed poverty trends such as census tracts for concentrated areas of high poverty. They used the number of children in Essex County Cities and compared it to the the amount of children in poverty in those cities, for the years of 2000 and 2015. Henceforth, they created an arguement stating that Child Poverty rates have risen within those 15 years, and even by 50% in some areas. The only issue I have with some of this data is that in some cities, we see a decrease in child population - and while there is an increase in child poverty in those areas, I feel like the reduced number of children in that area plays a big part in the so called "Increased Child Poverty Rates".

Vulnerability and resilience in this artifact are defined by the high concentration of child poverty in Essex County. They are measured using the Census from 2000 and 2015 which show how there is a trend in the percentage of children who expereince poverty within the county. Majority of the children living in poverty are currently living in heavilyu concentrated poverty neighborhoods like Newark, Irvington, and the Oranges. Although the affluent town of Milburn is nearby, it is unclear how these children continue to live below the poverty line in Newark even though the towns are only 6 miles apart.

As a sesearch from the Rotgers University, the students or researchers support:

- The child poverty in becoming more concentrated. With the numbers next to us, we can say that a 52.5% of the poorest childs live in census were the concentration is above a 40%

- Inner-ring suburbs of Orange, East Orange, and Irvington have seen the largest increases in child poverty.

- Essex County’s smallest municipalities have very low child poverty, although many have seen their child poverty rates increase by more than 50 percent since 2000
