The current Union Bridge on-site limestone quarry has approximately 3-4 years of reserves remaining. Expansion of the Union Bridge Quarry occurred several years ago into the “Clensonville” area. The Clemsonville expansion provided several more years of limestone providing time for the permitting and development of the New Windsor limestone quarry located 5 miles to the southeast.
The New Windsor limestone quarry has been permitted and is currently being developed to provide cement grade limestone to the Union Bridge Plant. The New Windsor quarry is an 800 +/- acre tract of cultivated fields located approximately 5 miles southeast of the Union Bridge plant. Lehigh has owned the property since the 1950’s and the primary use is “agriculture”. The entire New Windsor site is permitted for extraction and/or overburden stacking providing a total available mining area is 535 acres. The New Windsor quarry will be the long-term limestone supply for the Union Bridge plant when the close proximity reserves from the existing quarry are depleted.
Transportation of limestone from New Windsor quarry to the Union Bridge plant will be conducted via a 7.25 km belt conveyor, partially overland and partially underground.
The development of the New Windsor Quarry impacted a stream and its’ tributaries along with the wetland areas called “5-Daughtors Run.” The total permitted impact was close to 3.2 km of stream and approximately 0.8 hectares of wetlands. The Stream & Wetlands Impact Permit required Lehigh had to mitigate for the total wetland impact of approximately 0.8 hectares wetlands and 2416 meters of perennial stream.
Located near the Union Bridge Clemsonville expansion, Haines Branch valley provided such a length of creek where Lehigh controls the total length of the creek valley. Haines Branch is a perennial stream that has been impacted by farming and cattle grazing over the last 100-years.
The restoration / mitgation of the Haines Branch section, includes seasonal ox-bow wetlands, buffers of warm season grasses and mixed forest types capable of sustaining in karst topography. Selection of plant species and hydraulic manipulations achieved habitat for host insects, passerine birds, waterfowl, small mammals, furbearers and herptilies. Whitetail deer and waterfowl visit the Haines branch valley. The restoration has provided habitate for Leopard frogs, various specieis of turtles and Black Nose Dace minows. Figures 1 & 2 depeict Haines Branch prior to the restoration / mitigation project. Figures 3 & 4 represent Haines Branch post mitigation project. Figures 4 & 5 show the newly planted meadow and the beginning creation of wetland areas.
Ongoing nature projects:
Haines Branch mitigation is an on-going habitat project. Quarterly stream and wetland monitoring occur along with invasive plant species management. Restoration and replanting of various damaged (by deer as food source) or dying plant and forest species take place in the spring and fall. With the on-going management of the Haines Branch Restoration, the habitat goal is to provide an environment for bats and various bird species.
