The acquisition of permits for construction, water withdrawal, and waste disposal operations is governed by laws and regulations that limit or prohibit construction or drilling activities in sensitive areas such as wetlands, wilderness areas, and areas containing endangered or threatened species or their habitats. These areas may also require investigatory and remedial actions to mitigate pollution conditions arising from Greylock Productiona' operations or attributed to previous operations, as well as reclaim and enforce obligations to reclaim and abandon well site impoundments and pits.
