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)

Smart autoalarm guardrail is designed for helpping people emergency contact and remind the other drivers when car accident happen in remote area. People will drive on some remote area, or late night. If car accident happens, might be no one know the accident is happen. This design is help the litigant automatically make a emergency call, and send the location through the GPS when the car is crash the guardrail. As well as, it can turn on/flash the light within the accident area to warn the other drivers.

This design could help people in an unknow emergency situation, for example, the driver pass out when the traffic accident happen, and this design can help people to save life. However, I think this concept design might be cost a lot if it is applied into real life, because it means there are lots of guardrail need to install this system, and the government also need to prepare another extra fee for repair the guardrail after every accident.

Smart Guardrail is autoalrm and could be send location to the nearset emergency centre by GPS when the car crash into the guardrail. As well as the warning light within the area will be swithched on to avoid the potential sencond accident. The system is design to install into the highway guardrail, and use the circuit to make the system work. Therefore, the materials might be include electrical wire and circuit, and also plastic caution lights.

Smart Guardrail is considered as a good concept design, because it can be solve the emergency problem for traffic accident in some situation. This design is applied a common materials and method to solve problem. It is a small change and might make a big influenced. But the design could be used or not is depend on the cost would be proportional to the value or not.

This concept design is create a market which is within more functions and technologies for guardrail. In the existing market, there are some good design highway guardrail, such as EZY-guard smart guardrail. Most of the existing product are applied outter shapes and physical structures rather than some electrical technology. Compare to the existing products, this concept design is more challenged by the cost.
