Requirements by government agency don't require total cleanup

Hi Noriko, Local equivalent standards can be used in place of U.S. government regulations for SSc3 in addressing sites where development can be complicated by environmental issues. If a regional government has designated this site as a brownfield, there is an implied and undeniable concern with regard to contamination. This said, there can be several ways to remediate a site without removal of the contamination as long as it no longer poses a threat. Brownfield sites can be difficult to assess proper remediation given the fact there is no one-shoe-fits-all standard. This is why regional authorities are often better qualified to establish recommended remediation requirements. Apparently these are being addressed by the mandated measures you’ve stated, so I don’t see an issue as long as you comply with the authority having jurisdiction.
