Analysis and research methods to comply with the strict soil disposal regulations of Chiba, Tokyo Bay, and Saitama.

Analysis and research methods to comply with the strict soil disposal regulations of Chiba, Tokyo Bay, and Saitama.

In the Tokyo metropolitan area (Chiba, Tokyo, Saitama, etc.), the disposal of construction residual soil is subject to some of the strictest unique regulations and additional controls in Japan, aimed at preventing the inflow of soil from other prefectures and inappropriate embankment. This service is a specialized analysis and investigation solution designed to ensure compliance with these complex local acceptance standards. It selects the optimal acceptance sites based on a complete mastery of the rules in each region, such as the "5-point mixing method" for 5000m3 of excavated soil under Chiba Prefecture regulations, the "mixing prohibition and pinpoint sampling for sea reclamation" for every 2500m3 at Tokyo Port, and the "sampling standard up to the top 50cm" in Saitama Prefecture. Through GeoTech's reliable process, screening of over 45 items, including additional parameters such as dioxins, oil content, and fluorine, is conducted efficiently, significantly reducing excessive investigation costs.

Designated Investigation Agency | Voluntary Investigation to Prevent Development Stagnation Due to Soil Contamination | Geotech

To prevent development setbacks due to soil contamination before purchasing land, we propose buyer-led historical investigations and voluntary Phase 2 sampling for risk mitigation.

This is a solution that explains the comprehensive voluntary soil contamination investigation conducted by the buyer to prevent business setbacks caused by "soil contamination," which is the greatest potential risk in land transactions and real estate development. Rather than relying solely on information disclosure from the seller, the investigation aims to ensure safety before land purchase, starting with Phase 1, the "Buyer-side Historical Investigation," which thoroughly uncovers the history of past use of specific hazardous substances and the potential for underground infiltration. If further risks are a concern, a "Voluntary Phase 2 Investigation" will be conducted on-site, where soil gas and sample sampling, along with official analysis, will quantify the presence and concentration of contamination as scientific evidence. This approach effectively avoids critical development risks such as unexpected contamination discoveries leading to delays in construction schedules or business setbacks after the commencement of construction work. In the event of contamination being discovered, it is also possible to calculate countermeasure methods and purification costs in advance, allowing for advantageous negotiations regarding warranty clauses and price adjustments in the sales contract. We provide high-precision investigation services unique to designated investigation agencies that support asset value preservation and safe real estate investment.

Designated Investigation Agency | Blocking Soil Contamination Risks in Factory Site Transactions | Geotech

To successfully acquire factory sites and conduct corporate M&A, we provide thorough risk avoidance measures through buyer-led historical investigations and voluntary sampling.

This is a self-investigation solution aimed at preemptively blocking the greatest management risk of "soil contamination" in corporate M&A and real estate transactions involving former factory sites, thereby avoiding corporate environmental liabilities. Instead of relying solely on self-reports from the seller, it thoroughly clarifies the past operational history and handling of hazardous substances through a "buyer-led historical investigation." Furthermore, for areas where risks are confirmed, a "voluntary Phase 2 sampling survey" is swiftly conducted on-site, quantifying the contamination levels of soil and groundwater as scientific analytical data. This allows for the complete prevention of the risk of incurring enormous remediation costs and the collapse of business plans after purchase, all before the contract is signed. Utilizing extensive experience and expertise as a designated investigation agency, we provide comprehensive support from optimal risk assessment to early cost estimation of countermeasures to prevent future asset value decline. This is an essential environmental due diligence to fulfill accountability to stakeholders and establish safe and transparent business deals.

Designated Investigation Agency | Comprehensive and Rapid Soil Contamination Survey | Geotech

To avoid delaying investment decisions for purchases, we provide a rapid survey that seamlessly integrates historical research, voluntary sampling, and contamination assessment.

This is a highly efficient, seamless self-investigation solution that meets the demands of purchasing agents who want to quickly assess soil contamination risks to the fullest extent within the limited negotiation period for land sales. The traditional method of splitting orders among multiple investigation companies by phase can lead to significant time losses in vendor selection and information handover, risking delays in investment decisions for purchases. Our service fully utilizes our expertise as a designated investigation agency by the Ministry of the Environment, integrating the entire process from the start of the "buyer-side historical investigation" to on-site "voluntary Phase 2 sampling investigation" in cases of suspected contamination, rapid official analysis, and final contamination risk assessment into a single seamless line. By flexibly organizing our own high-speed drilling equipment and specialized teams, we dramatically shorten lead times, swiftly eliminate critical development risks such as construction delays and project stagnation, and lead time-sensitive business deals to success with overwhelming speed.

Designated Investigation Agency | Voluntary Soil Contamination Survey in the ESG Era | Geotech

To fulfill environmental compliance and corporate social responsibility, the buyer's side conducts rigorous historical investigations and sampling to completely eliminate potential environmental risks.

This is a clean self-investigation solution developed for advanced companies, publicly listed companies, and foreign investment corporations that emphasize ESG management and environmental compliance, balancing the defense of brand value and the mitigation of environmental liabilities. In modern business, overlooking soil contamination associated with land transactions leads not only to financial losses but also to fatal management risks such as damage to corporate image from media coverage and a collapse in ESG ratings. Our service conducts a thorough audit of the handling history of hazardous substances from the Taisho and Showa eras through a "buyer-side historical investigation" based on the highest compliance standards. If there is even a 1% possibility of contamination, we immediately deploy a "voluntary Phase 2 sampling investigation," conducting rigorous sampling and official analysis in accordance with international standards. This allows for the complete quantification of environmental risks and enables high transparency in information disclosure to stakeholders and investors, while completely eliminating the development risk of sudden contamination discovery after purchase.

Designated Investigation Agency | Soil Investigation of Narrow Sites and Operating Buildings | Geotech

Even in narrow sites with existing buildings or operating factories, the buyer's independent investigation using specialized small drilling equipment will identify soil contamination risks in advance.

This is a self-investigation solution designed to accurately assess soil contamination risks while maintaining existing factory buildings or structures on operational sites, or in narrow urban areas where large machinery cannot access. Typically, general environmental surveys assume that the site will be cleared, but decisions regarding land purchases and demolition budgets need to be made before contracts are signed, and waiting for the site to be cleared would not meet business timelines. Our service first identifies the past layout of machinery and the locations of hazardous material handling pits within existing buildings through a "buyer-side historical investigation," accurately narrowing down areas of contamination concern. In the subsequent sampling process, we utilize our own ultra-compact and simple drilling machines that can operate in low-ceilinged interiors and narrow corridors, completing a "voluntary Phase 2 sampling investigation" precisely without disrupting operations. This unique technology allows for a reliable understanding of underground contamination conditions and development risks while leaving the buildings intact before purchase.

Designated Investigation Agency | Early Soil Contamination Survey During Operations When Rebuilding Automobile Maintenance Factories

To prevent delays in construction during factory rebuilding and facility decommissioning, we propose an early soil contamination survey to clearly identify potential risks around the equipment from the operational stage.

This proposal is an early soil contamination survey package aimed at owners, management, and general affairs departments of currently operating automobile maintenance factories, designed to clarify potential risks on-site without halting operations. In maintenance factories that have been in operation for many years, there is a risk that cleaning solvents such as trichloroethylene, which fall under specific harmful substances, as well as lead, hexavalent chromium, cadmium, boron, and fluorine from past soldering, putty polishing, and anti-corrosion chromate plating processes, may have permeated underground from aging pipes and pits. If these issues are left unaddressed and the factory faces reconstruction or the closure of specific facilities, there could be unexpected high-cost construction and significant delays in the schedule. As a designated investigation agency by the Ministry of the Environment, we provide comprehensive support for planned environmental risk management and cost reduction, from detailed historical verification of the factory's operational history to narrow-site and indoor sampling using a completely electric simple boring method (SCSC method) with zero exhaust emissions, depth-specific boring surveys to narrow down the three-dimensional extent of contamination, and rapid public analysis of leftover soil from reconstruction.

Soil contamination survey [Providing highly accurate and reliable investigation and analysis]

We provide highly accurate and reliable soil contamination surveys!

Under the Soil Contamination Countermeasures Act (Soil Contamination Act), owners of land that was a factory or business site related to the use of specified harmful substances that have been discontinued must have the soil contamination status of that land investigated by a designated investigation agency and report the results to the governor of the prefecture. Additionally, some ordinances may have a broader scope of application for soil contamination investigations than the Soil Contamination Countermeasures Act. For example, the Tokyo Metropolitan Environmental Protection Ordinance requires that when a factory or designated work site is discontinued or removed, not only current but also past handled harmful substances must be investigated, and land alterations of 3,000 m² or more are also subject to investigation. Nisshin Environmental Investigation Center is a designated investigation agency and also an environmental measurement certification business, so if the possibility of soil contamination cannot be ruled out based on the investigation of materials, we will provide highly accurate and reliable investigation and analysis in accordance with the legally prescribed methods (official methods). *For details, please request materials or view the PDF data from the download.

Soil Contamination Survey: Overview Survey / VOC Boring Survey

We provide highly accurate survey results! Experienced technicians will conduct soil sampling and soil gas sampling.

At Kyoa Development, we conduct contamination confirmation surveys as the next step following historical investigations. The "Overview Survey" involves collecting and analyzing soil and soil gas samples to determine the presence of soil contamination by specific hazardous substances at 10-meter intervals.
