We hope this finds you all healthy and safe. All of us at Waste Management remain committed to Stony Hollow Landfill and to being a trusted waste and recycling partner in the Dayton community.
Together, we are working alongside all of you to help flatten the curve in Ohio as we deal with COVID-19. We are also aware how important it is for us to remain steadfast in our commitment to our people and the environment. As an essential business, we have continued to serve our communities, while practicing social distancing and employing increased cleaning standards. We have and will continue to use the highest safety standards and closely monitor all the site safeguards we have in place at Stony Hollow Landfill.
As you know, our team has worked diligently to resolve the odor issues and we continue to do so. We are maintaining all existing programs and odor control systems and this week we begin our routine gas well installation to further gas collection.
Our site activities continue to focus on routine monitoring and inspection programs, assuring the extensive control systems now in place continue to function at their peak. We continue to maintain gas collection systems and the odor control improvements made with the installation of the cover shown below.
The engineering design for the 2020 landfill gas construction is complete and construction is scheduled to begin in mid-April. The routine gas construction will focus on new and replacement gas extraction wells and associated piping to be installed on the southern slope of the landfill. The project is expected to be completed by the end of May. The planned work continues to provide improvements to our landfill gas control systems.
Odor Surveillance Program Continues: Our routine odor surveillance continues at a frequency of one time per day, five days a week with two additional random surveys performed each week. We continue to investigate and document all odor complaints received. Since 2016, we have experienced more than a 93% reduction in the number of odor complaints received annually. Since activating the cap, a decrease in intensity and scope of odors continues. Results are maintained on site and are available for agency inspection. As we continue any site maintenance and gas well installation work, we will issue potential odor alert notifications when we expect there’s a potential for off-site odors.
We also continue to share monitoring activities at the quarterly Stony Hollow Forum attended by members of the community, City Staff, Solid Waste District staff and Moraine.
Odor Alert Line Remains in Place: We continue to maintain several ways for individuals to notify us of potential odors. The Stony Hollow Landfill Odor Alert Line is open for messages at 937-356-6203. You can also file an odor alert online atwww.stonyhollowlandfill.com.
Odor Management Plan Remains in Place: We maintain the Ohio EPA approval on our odor management plan described above. We continue to operate in accordance with the approved plan and are committed to update the plan as necessary as site activities dictate. The Ohio EPA sets clear guidelines and measurement criteria in their approval of the revised plan.
No Changes to Synthetic Cap and Gas Well Collection Systems: The synthetic cap and gas well collection system continues to function and perform well. This system continues to control odors and proactively address future issues. We routinely inspect the area to assure its continued effectiveness. Our site gas technicians are on site for daily inspections to ensure all wells are operating properly and the vacuum is being applied. Gas well monitoring and tuning of the well field continues.
