Environmental Excellence Nomination
Northeastern Mine Reclamation Project
Mountain Valley Stone successfully completed outstanding work in site reclamation after the use of an area for mineral mining. This project included outstanding work in revegetation and results from implementing environmental technologies. Involving and giving students educational opportunities and using aerial drone photography to examine the progression of the project shows that meeting this requirement was taken far above regular obligation. This site will continue to provide educational opportunities for students interested in environmental work and while using these same forms of technology, they can help Mountain Valley Stone to continue to monitor the progress of the site as it is restored back to natural habitat.
Mountain Valley Stone has been awarded a Gold-level certification under the ANSI/NSC 373 Stone Sustainability Standard.
Because of this rigorous certification, architects and owners can be assured that stone for their buildings is produced to the highest standards in the industry, in an economic, environmental and socially responsible manner.
Ensuring stone is produced in an economic, environmental and socially responsible manner.

Where We Stand
1833 Tons CO2e
In view of the last 6 years, Mountain Valley Stone’s energy consumption per ton of stone produced has been on an overall incline due to higher diesel consumption per ton of stone produced. It is the goal of Mountain Valley Stone to have at least a 5% reduction in diesel consumption per ton of stone produced over the 2019-2020 period, and a reduction for immediate years following.
1833 Tons CO2e
The three largest contributors to Delta Stone Product’s direct emissions consist of diesel exhaust from the operation of wheel loaders, haul trucks and excavators. These emission sources share best practices which are key to reducing the greatest amount of emissions: managing idling times and operating efficiency. Mountain Valley Stone is committed to effective training of employees in order to improve the air emissions and overall carbon footprint of operations.
Excess Process Materials & Waste
120360 Tons of Overburden
47.42 Tons of Solid Waste
The only excess process material generated at Mountain Valley Stone is overburden. Overburden consists of top-soil material that is stripped in order to expose mineable material. It is important to note that although Mountain Valley Stone has generated large amounts of EPM’s in the last two years, all of this material is being saved for reclamation purposes and will be vital for the restoration of the mine.
Machinery Idling Times
28% Annual Decrease
From June 2016 to May 2017, Mountain Valley Stone achieved a drastic 28% decrease in idling percentage of run-time on heavy equipment. Six of the machines on the quarry are tracked using an integrated GPS system that allows the manufacturer to provide monthly reports on idling times, gallons of diesel consumed, total run-time and a comparison of the fleet’s statistics to the regional and national averages. Due to greater awareness and training from these reports, it has been a priority for Mountain Valley Stone employees to reduce idle run time while operating equipment.
