N.M. Admin. Code § 19.2.10.22
Unless otherwise authorized in writing by the commissioner, an easement or right of way shall not be used for any other or additional purposes or by any other or additional parties except those expressly identified in the grant of easement or right of way. Unless expressly stated otherwise in the grant of easement or right of way, the commissioner reserves the right to grant easements or rights of way to third parties over, under, upon, through, across or parallel to an existing easement or right of way; provided, however, that the commissioner shall not approve such subsequent easements or rights of way if, in the commissioner's discretion, such co-use would present a safety hazard or otherwise unreasonably interfere with the existing easement or right of way. When a subsequent easement or right of way is permitted, the commissioner will require the subsequent grantee to post a bond or other surety to insure payment of damages, if any, which are done to the prior grantee's improvements and installations unless the prior grantee waives this requirement.
