EDITORIAL COVER LETTER / 편집국에 보내는 요청

We request independent reporting into a multibillion-dollar-scale redevelopment on the site of a former chemical plant in Incheon. Our concern is not merely whether waste lime once existed, but whether regulators, developers, and investigative authorities can document adequate environmental cleanup decisions and building-specific ground-safety verification before and during occupation. The development is publicly described as approximately 13,000 households. The allegations are serious; they are not findings of proven criminal wrongdoing.

THE PUBLIC INTEREST AT STAKE

OCI Holdings publicly describes City O Ciel, developed by its subsidiary DCRE on and around a former industrial site in Incheon, as a project planned for approximately 13,000 households. The submitting journalist estimates a potential population of around 40,000; this population estimate has not been independently verified. The project’s scale warrants transparent scrutiny of legacy industrial waste, environmental compliance, and geotechnical safety.

WHAT THE ACADEMIC STUDY ACTUALLY SHOWS

A 2016 peer-reviewed paper by Eun-Chul Shin and Ae-Young Lee, “Geotechnical Engineering Characteristics and Consolidation Settlement Estimation of Waste Lime Landfill,” examined waste-lime landfill samples and calculated theoretical primary and secondary consolidation settlement under specified assumptions. Materials supplied by the journalist refer to theoretical figures approaching two metres in a parliamentary briefing. Neither the study nor those figures establish that a particular City O Ciel building will settle by two metres or collapse. Independent experts should assess whether the study is relevant to particular parcels and foundations, and review site-specific boring logs, soil improvement, pile design, monitoring, and settlement predictions.

HAKIK BRIDGE: PHOTOGRAPHS AND A TESTABLE QUESTION

The journalist has photographs labelled as showing material near the P6 and P8 piers of Hakik Bridge, as well as correspondence with Korea Expressway Corporation and local authorities. Photographs cannot establish chemical composition, provenance, or whether disposal was unlawful. The question is whether representative samples were taken, which laboratories tested them, what geographic area was inspected, and whether any historical deposits remain outside the scope of later inspections. A June 2026 reply reportedly described finding no additional illegal dumping; that should not be paraphrased as proof that no historical material exists.

PARLIAMENTARY SCRUTINY AND UNRESOLVED RECORDS

Materials provided include a 2023 National Assembly audit briefing that raised waste-lime and settlement questions, environmental advocacy material from 2018, official agency responses, and a public-interest audit petition. We ask journalists to compare the questions raised with subsequent inspection reports, sampling results, remediation decisions, geotechnical assessments, and any records explaining why particular areas were included or excluded. Some agencies have responded; the adequacy and consistency of those responses remain the subject of the journalist’s complaint.

COSTS, PROFITS, AND CORPORATE ACCOUNTABILITY

The journalist alleges that remediation could cost hundreds of billions of Korean won and questions whether financial incentives affected decisions about waste management. No independently verified remediation cost estimate or proof that DCRE or OCI Holdings earned trillions of won in net profit from improper disposal is presented here. Reporters should obtain environmental liability assessments, remediation budgets, actual project revenue and profit disclosures, and any correspondence between the developer and regulators. The companies must be offered a meaningful opportunity to respond.

THE QUESTION FOR THE STATE

If concerns about a major housing development have been raised repeatedly in academic, civic, parliamentary, and administrative forums, what evidence demonstrates that regulators and investigative authorities assessed them adequately? We request examination of the respective roles of Incheon Metropolitan City, Michuhol District, the Ministry of Land, Infrastructure and Transport, the Han River Basin Environmental Office, Korea Expressway Corporation, and the relevant investigative bodies. Institutional inaction, misconduct, collusion, or corruption should not be presumed; they should be investigated only on evidence.

SPECIFIC REPORTING REQUESTS

We ask for: (1) independent sampling and accredited laboratory testing where legally permitted; (2) access to soil investigation, remediation, and waste tracking records; (3) independent review of geotechnical design and settlement monitoring; (4) comparison of 2023 parliamentary questions with later government actions; (5) interviews with residents, academic specialists, regulators, and the developer; and (6) clear publication of findings, including facts that may rebut the allegations. We do not ask journalists to adopt our conclusions without verification.

EVIDENCE AND LANGUAGE

The supporting materials are predominantly in Korean. The originals will be supplied unchanged, together with an English evidence index, brief translations of key passages, dates, and source-page references. Copies intended for media review should have unrelated personal identifiers redacted. Photographs are identified by the location and date stated by the submitting journalist, subject to independent verification.

FAIRNESS AND VERIFICATION

Please seek written responses from DCRE, OCI Holdings, relevant contractors, Incheon Metropolitan City, Michuhol District, the Ministry of Land, Infrastructure and Transport, the Han River Basin Environmental Office, Korea Expressway Corporation, and relevant investigative authorities. We welcome publication of findings that confirm or disprove the concerns. No assertion of corruption, deliberate endangerment, imminent collapse, or illegal disposal should be treated as established without supporting evidence.
