A Field Wide Stormwater Management Plan (SWMP) for the La Plata lnfill Program is on file at the XTO Energy Inc. office. A Site Specific SWMP with a Site Plan will be developed for each location. Inspections of the project site and maintenance of BMP's installed shall be conducted in accordance with the CDPHE CDPS permit & field wide plan. Spill Prevention and Counter Measures (SPCC) for the La Plata lnfill Program is on file at the XTO Energy Inc. office. The Field SWMP and Site Specific SWMP each address SPCC during construction operations. See attached diagram for site specific BMP's. 0b2699e1-4762-4dc3-9575-5226d7fc285c 400147473 5 Wildlife General Operating Practices The Hocker #4-35 will be drilled from the existing Hocker #35-2 well pad to reduce surface disturbance impacts. Reduces area necessary for well pad construction. Utilize existing infrastructure for operations. A closed-loop mud system will be used during drilling operations. Surface equipment that could be potentially damaging to wildlife will be fenced with cattle panels. Prevents wildlife entry to potentially harmful equipment. The access road will be gated in order to restrict general public access. Construction, drilling and completion activities will be scheduled to avoid critical winter use periods for deer and elk December 1 - April 15. Recycle drilling fluids. Mud systems are dewatered, recycled and water is reused during drilling operations, reducing the amount of water needed to be trucked for drilling operations. Mud can be transported to next drilling location, reducing truck traffic to dispose of drilling fluids. Adhere to the developed weed management plan pursuant to both the La Plata County Land Use Code and Colorado Noxious Weed Act. Protects the productivity of adjacent wildlife habitats. Screen exhaust and vent stacks to preclude avian perching. Standard wildlife friendly seed mixes developed by the CDOW specifically for the San Juan Basin will be used for reclamation. Educate employees and contractors on wildlife conservation practices, including no harassment or feeding of wildlife. Forbid use of firearms and dogs on location. Utilize bear proof dumpsters and trash receptacles for food related trash at all facilities that generate such trash. 400147473 Leroy & Glenda Hocker
