According to a joint investigation between the United Nations Development Program (UNDP), and the Vietnamese Office 33 and the MONRE, about 250,000 cubic meters of dioxin- contaminated soil and sediments will required cleanup with an estimated cost of $250 million - almost triple the cost of Da Nang.137 Dioxin contamination at the ▇▇▇▇ ▇▇▇ airbase resulted from the storage, loading, spillage, and handling of Agent Orange and other herbicides, especially in the 1965-1971 period.

These converted concentrations are then added together to determine the “toxic equivalence concentration” (“TEQ”) of the dioxin and furan compounds as a whole.
Dioxin means all of the seven 2,3,7,8 chlorinated dibenzo-p-dioxin congeners, ten 2,3,7,8 chlorinated dibenzofuran congeners, and twelve coplanar polychlorinated biphenyl congeners as follows.
Dioxin means all of the seven 2, 3, 7, 8-chlorinated dibenzo-p-dioxin congeners, ten 2, 3, 7, 8-chlorinated dibenzofuran congeners, and twelve coplanar polychlorinated biphenyl congeners in the following table:
Dioxin means polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans.
Dioxin refers to a large family of similar chemicals, including furans. The United States Environmental Protection Agency (U.S. EPA) has concluded that dioxin may cause cancer or other human health effects such as skin problems, liver damage, and reproductive issues, depending on exposures. Dioxin is not created intentionally; in this case, ▇▇▇▇▇▇ formed as a byproduct of Dow’s early manufacturing processes. This Action Memorandum discusses dioxin concentrations as the toxic equivalence quotient (TEQ) – a summed estimate of the relative toxicity of the congeners as compared to 2,3,7,8- tetrachlorodibenzo-p-dioxin. The proposed response actions include removing contaminated soil in people’s yards, replacing it with clean soil, and restoring grasses and plants. Eligible residential properties are those where soil tests show dioxin levels greater than the site-specific residential cleanup number of 250 parts per trillion parts (ppt) TEQ. U.S. EPA and Dow have agreed to enter into an Administrative Settlement Agreement and Order on Consent (MGI AOC), pursuant to which Dow will perform the removal action described herein with U.S. EPA oversight. This action will be conducted in accordance with Section 104(a)(1) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), 42 U.S.C. § 9604(a)(1), and 40 C.F.R. § 300.415 (Removal Action) of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP) to ▇▇▇▇▇ or eliminate the threats posed to public health and/or the environment. U.S. EPA has consulted, and will continue to consult with, the Michigan Department of Environment, Great Lakes, and Energy (EGLE)1 on MGI response actions. This action is anticipated to require one construction season to implement and is expected to begin in 2021. This action will be implemented by Dow, the potentially responsible party, under a CERCLA Section 106/122 agreement. As such, pursuant to NCP Section 300.415(k)(3), the requirements to terminate response after $2 million has been obligated or 12 months have elapsed from the date of the initial response do not apply.
