Environmental Land Surveying & Solutions (ELSS) was incorporated in 2005 by Elizabeth Gregg, President & CEO of Environmental Service Laboratories (ESL), Indiana, PA. With a few shallow well Erosion & Sedimentation Control Plans (E&S Plans) and 17 years experience in the natural gas industry via ESL, Ms. Gregg had a vision to create a full-service surveying and permitting firm. With the growth of the natural gas industry occurring faster than ever, the opportunity to create such a firm was seized.

ELSS first focused on the growing demands of local natural gas drilling companies by generating shallow well plats, conventional E&S Plans, pipeline surveys, and DEP/DOT permitting. The capabilities and staffing of ELSS grew adequately to both accommodate the needs of its current clients and position ELSS to expand into different markets, including construction and municipal infrastructure. Services added include GIS, field E&S compliance, 24/7 CBM frac baffle determinations, wetlands delineations, cut/fill determinations, and earthwork volumetrics. Unforeseen at the time, these additional services ultimately positioned ELSS to become a leading provider to numerous local and out-of-state operators currently focusing on the development of the Marcellus Shale in Pennsylvania.

ELSS outgrew several offices and moved into a new state-of-the-art office building in 2008 to allow for additional expansion. Located in the HighPointe at Indian Springs Business Center in Indiana, PA, ELSS is close in proximity to many of its clients and centrally positioned between the most active Marcellus Shale drilling areas in Pennsylvania.
