Liberty Stone & Aggregates - Clinton Quarry (LSACQ) is a recognized federally regulated mining and quarrying facility, licensed by the State of New Jersey, Union Township, and the Mine Safety and Health Administration (MSHA). LSACQ has over 100 combined years’ experience in the mining / construction / materials processing industries - generating single source material from our Clinton Quarry Location. LSACQ supplies NJ, NY and PA with same day delivery aggregate products, landscape boulders and topsoil. We can supply any and all of your project aggregate needs - from commercial and industrial, to residential and environmental applications - with site testing and sampling available upon request. We accept NJ Clean Residential Fill in accordance with our facility protocols as well.

Our mission is to provide our customers with consistent, high quality professional service through our equation:



As quarrying activities are completed to the limits approved by the Township of Union Quarry License, fill is required in a reclamation effort to return the quarried site to its original grades. The reclamation plan for the site has been approved by the Township of Union and the Hunterdon County Soil Conservation District. Only fill with the appropriate frequency of testing below the New Jersey Residential Direct Contact Soil Remediation Standards are acceptable for use at the site, and are subject to our review and formal approval prior to acceptance.

A protocol has been developed, and strictly adhered to, in order to screen sources for use in our site's reclamation.
