Welcome to SA Dunn Landfill

S.A. Dunn & Company, LLC

S.A. Dunn & Company, LLC owns a sand and gravel mining operation that has existed since the 1800s in the City of Rensselaer and the Town of North Greenbush. The reclamation required as part of the mining permit includes grading with construction and demolition debris fill in accordance with strict modern regulations (see About Us page).

Permit Renewal

S.A. Dunn & Company, LLC submitted it's renewal application to NYSDEC. The permit renewal will not change or expand its current mining or C&D operations. The application also includes a modification to the facility to include an earth berm along to the northern and eastern side of the site that will reduce its visibility from the north. Permit application documents are available for review at the site, the Rensselaer Public Library, the NYSDEC Region 4 offices or website (https://www.dec.ny.gov/chemical/117071.html#Permit) or by clicking on “Permit Renewal Application” above. An information session will be held on June 14, 2022 from 7PM to 9PM at the Rensselaer City School Auditorium for community members interested in hearing about the facility and the permit renewal process. The informational session will also be accessible virtually on June 14, 2022 from 7PM to 9PM at https://wasteconnections.zoom.us/j/91932452654 or by telephone at (929) 436-2866. Another session is planned for the summer with information provided here for that second session as it is scheduled.

Current Events

Some in the community expressed concerns about PFAS in surface and ground water around our facility, so we did more than listen, we acted. We hired an outside engineering firm to collect numerous samples for PFAS over the last year and a half. Those samples were analyzed by an independent and accredited lab. The conclusions were clear, and matched DEC’s findings: There is no PFAS issue at or around S.A. Dunn, and we are not contributing to any PFAS concentrations in groundwater or surface water. Our latest efforts in January 2021, included collecting PFAS samples from our groundwater monitoring wells and surface water monitoring locations. Detections of all PFAS compounds, including PFOA and PFOS, were well below the State’s 10 ppt drinking water standard, and in many cases were non-detectable, consistent with background readings for PFAS found across the state. Our commitment to being transparent means we will continue to collect samples from the groundwater monitoring wells surrounding the facility, and from the water flowing in the Quackenderry Creek both upstream and downstream of S.A. Dunn. We will also continue to analyze water samples for PFAS and share those results with the community. It’s our responsibility to assure through sharing information with our neighbors to show there are no reasons for concern. We want to focus on facts, not unfounded claims to heighten needless fears.
MAY 2021 UPDATE – In May 2021, SA Dunn analyzed “split” samples from groundwater monitoring wells sampled by NYSDEC contractors. The May 2021 results confirm conclusions from prior sampling efforts.

New York State DEC has been regularly testing the air quality surrounding our facility since 2019 and summarizes findings on a regular basis. In April 2020, they issued findings from additional testing at the school facility to our north for volatile organics (VOCs), particulates and certain metals and found levels “…typical of the general air quality for a suburban area.” We are pleased to have this affirmation that our facility’s operations are protective of the health of our neighbors.

Economic and Fiscal Benefits Analysis
