SHERBURNE – A map of where natural gas companies have leased land for drilling and transmission purposes will be presented as part of the Rogers Environmental Education Center’s Earthfest event on Saturday.

Members of the drilling opposition group, called CDOG, invite the public to see how their communities could be impacted by possible permitting, testing, drilling and pipeline infrastructure.

The eight annual Earthfest at Rogers is scheduled from 11 a.m. to 4 p.m. on Saturday at the Rogers Center, 2721 state Hwy. 80, in Sherburne. Environmental Educator Laura Carey said the event is a celebration of Earth Day and intended “to raise people’s awareness about the natural world and about how human actvities can in fact impact the environment.”

The CDOG organization, representing Chenango, Delaware and Otsego counties, has been researching public records since January in order to locate and record every leased property in the three counties. The information was later transferred into large-scale town maps. According to its website, the group plans to further use its database of information to reach out to lessors, to neighbors whose properties will be subject to compulsory integration and to non-resident landowners.
