We have completed work for the year at our House Street property. As we summarized in prior posts here and here, that work included tree cutting and staging, stripping some topsoil, relocating some waste (no waste will be left exposed over the winter), and stabilizing soil and seeding for the winter. We performed air monitoring during that work in accordance with our air monitoring plan, and when work resumes next year we will continue to perform air monitoring.
We have regularly posted the air quality data to this blog, and you can find the latest data here. This data continues to show levels were far below action limits, with no issues or concerns identified.
Air quality data is not the only data our real-time air monitoring systems collect. As explained in our air monitoring plan, we also utilize an onsite meteorological system (located at Station 3 on the south perimeter of the property) to monitor wind speed and direction, temperature, and relative humidity. In particular, wind speed and direction are continuously recorded to track the actual onsite wind conditions and ensure the effectiveness of our monitoring.
All of our wind data to date has shown that the wind at the site blows in the directions where we have monitors. The map below shows the areas of work during fall 2023 along with the “wind roses” showing the predominant wind directions and perimeter dust measurements for those time periods.
We will continue to use all of our air monitoring data, including wind data, to ensure appropriate and effective air monitoring while work is occurring at the site. If there is an exceedance of project action levels at the fence line monitors, we will contact regulators and nearby residents to communicate the exceedance, explain the mitigation measures being taken, and provide an update.
Wolverine will be using this blog to keep the community informed as work progresses in the weeks and months ahead. In addition, residents with questions are encouraged to contact Wolverine directly at HouseStreet@wwwinc.com or (616) 866-5627.
