2018年3月，明尼苏达污染管制局（MPCA）宣布形成蒸汽入侵利益攸关方咨询小组，为MPCA提供投入，因为它们为明尼苏达州商业和工业物业的蒸汽入侵减轻了最佳管理实践（BMP）。利益攸关方咨询小组由几个受影响行业的个人组成，包括商业房地产和重建，非营利组织，商业贷方，授予机构，法律公司，国家机构和环境顾问。来自Braun Intertec的项目工程师Kaitlin Thell Ouverson被MPCmanbet体育滚球A邀请到代表蒸汽入侵利益相关者咨询小组的环境咨询业的三个人之一。

Mitigation of potential chemical vapor intrusion into buildings is a concern in many states as they seek to protect the indoor air for building occupants located near contaminated soil and groundwater sites, including brownfield sites undergoing redevelopment. Braun Intertec engineers have been designing and implementing蒸汽缓解系统for buildings located on and near contaminated sites for over 20 years. With new research and guidance documents released by the United States Environmental Protection Agency, the MPCA has been revising BMPs for investigation and mitigation of contaminated soil vapors. To date, the MPCA has developed investigation requirements for all occupied structures and BMPs for vapor intrusion mitigation of single-family residential structures.

So, what’s next?

The first Vapor Intrusion Stakeholder Advisory Group meeting is scheduled for mid-April 2018 and the group’s goal is to release a BMP for vapor intrusion mitigation of commercial and industrial properties in the fall of 2018.

How can I contribute to the BMP development process?
