Introduction The Colorado Noxious Weed Act (C.R.S. Title 35, Article 5.5) declares that certain undesirable plants constitute a threat to the "continuous economic and environmental value of lands of the state" and requires that these "noxious weeds" be managed on private and public lands. The Act further declares that control of noxious weeds should use methods that are least damaging to the environment but also practicable and economically reasonable. Ursa Operating Company, LLC (Ursa) started operations in the Piceance on April 1, 2013 and will be responsible for management of noxious and undesirable species identified on land leased associated with these assets. The local government(s) management of noxious weeds for Ursa assets (known as Battlement Mesa), is Garfield County which requires that land owners or persons or entities leasing the land within the county manage noxious weed infestations on their respective land. By implementing a Noxious Weed Management Program, adverse economic and environmental impacts will be minimized for Ursa and surrounding stakeholders. Maintaining control of noxious weed populations within Ursa assets is important to keep the cost of noxious weed abatement, stormwater, and revegetation to a minimum. Since the three (3) elements are intertwined; improvement in one (1) area will facilitate improvements in the other areas of concern. It is also vital that the expansion of noxious weeds from Ursa assets to private land not associated with oil and gas exploration is monitored closely to ensure weed abatement measures are effective. For the most successful management of noxious weeds, regular communication between Ursa and property owners with adjacent land should be developed. This plan is intended to provide Ursa with a noxious weed management outline for the area of concern — in this instance, the asset known as Battlement Mesa. The objectives of the plan include: providing basic environmental information about the sites, locating and mapping of noxious weed populations, outlining and evaluating possible treatment methods, and establishing preventative measures to minimize noxious weed expansion. This plan will also provide an amendable document for current and future Ursa land managers. 2. Site Characterization Ursa assets covered under this plan are located in Garfield County in western Colorado (refer to Figure 1 for a map and Appendix A for listed locations). The assets can be found using the Public Land Survey System (PLSS) in Appendix A or by reviewing the map in Figure 1. The vegetative communities that characterize these sites include: sagebrush, rubber Rabbitbrush, snakeweed, Gambel oak, bunch grasses and pinyon juniper. This highland is characterized by moderate moisture levels, moderate temperatures and a moderate growing season. Snow is typically present on site from mid-November to late -March, with an average of 80-90 frost days per year. The soil type varies across assets. For more information on soil type, refer to Appendix B and Figure 2. The potential treatment area with regards to noxious and undesirable species will include appropriate and applicable pads, right of ways (ROWs) including access roads and pipeline ROWs, topsoil stockpile if applicable, and land surrounding the Ursa assets that has been disturbed by related Ursa activity. Ursa Operating Company Battlement Mesa PUD Noxious Weed Management Plan 1 3. Weeds of Concern To meet the requirements of the Colorado Noxious Weed Act (ACT), the operator shall conduct prescribed management techniques for noxious weeds control and prevention. Species warranting prescribed management control and prevention are included within the Colorado Noxious Weed Lists: List A — designated for statewide eradication; List B — managed to prevent further spread and, for selected species, designated for eradication in large areas; and List C — of more localized concern, but for which the State will provide education, research, and biological control assistance to jurisdictions that choose to manage the species. The complete Colorado Noxious Weed List can be found in Appendix C. In addition to the state wide weed list, individual counties have their own noxious weed lists. The county lists are comprised of noxious weeds from the state list that are more specific to the area of concern. Garfield County has designated twenty (21) of the seventy four (74) species from the Colorado Noxious Weed List to be likely species found in the vicinity of their jurisdiction. Appendix D contains the Garfield County Weed List, and specific details can be acquired through the Garfield County Noxious Weed Management Plan available online. 4. Weed Inventory Noxious weed surveys are conducted on Ursa assets prior to any earth disturbing activities. Please refer to Garfield County Impact Analysis for the BMC D well pad location for the weed survey. Additional surveys will be conducted annually by qualified individuals to ensure noxious weed treatments and noxious weed populations. Populations of noxious weed infestations will be mapped by qualified individuals using global positioning units (GPS) units. The Noxious Weed Inventory Form, Appendix F, can be used to provide supplemental survey information if the surveyor deems it appropriate. The surveys will provide a way to identify new noxious weed populations as well as an assessment tool for previously treated populations. The inventory is to be updated as the surveys are performed. There will be an annual review to assess the overall noxious weed populations and success of treatments applied. 5. Treatment Methods The treatment methods and descriptions listed below were obtained from the Mesa County Noxious Weed Management Plan (Mesa County, 2009). Management techniques include preventative, cultural, physical/mechanical methods, biological and chemical approaches. Optimal noxious weed management methods will vary with the environmental variables of the area of interest. Soil type and stability, grade, moisture regimes, growing season, pre-existing noxious weed populations, land use, water availability, weed type and stage of growth as well as the intensity of the infestations should all be taken into account when preparing a noxious weed management plan. The management methods should have minimal impact on the environment and be economically fitting for the Operator in charge of implementing the noxious weed management program. When assessing weed management on a property, it is important to evaluate possible modes of transportation for the noxious species. Areas to take into account include; waterways, roads, game trails, areas with livestock and equipment storage sites to name a few possibilities. The Ursa Operating Company Battlement Mesa PUD Noxious Weed Management Plan 2 transportation of noxious species is a problem shared by all the stakeholders in the affected area. Good communication should be established between the affected parties for proper management of the noxious weed populations. Most management plans utilize a combination of the treatments outlined below. 5.1 Preventative Methods Preventative methods include practices involving good land stewardship. These practices include, but are not limited to; using weed free certified products, erosion control measures, and regularly cleaning equipment. 5.2 Cultural Methods Cultural methods facilitate competition from desirable plants through actions such as; dense seeding, irrigation, carefully monitored grazing practices and fertilization. 5.3 Physical and Mechanical Methods Physical and mechanical methods include mowing, disking, hand removal, plowing, burning and solarization. The goal of these methods is predominantly to prevent seed production. Roots should be severed at least two (2) inches below the soils surface for optimal control. 5.4 Biological Control Methods Biological control methods involve the introduction of living organisms that are deleterious to the noxious weed species. This method is only applicable for infestations larger than five (5) acres in size, and rarely provides complete control of the noxious species. Frequent monitoring must be carried out with this method. 5.5 Chemical Control Chemical control can offer the most effective means of noxious weed control when applied at the appropriate time. Not all herbicides are equally effective against all weeds, nor can every herbicide be used in all settings. The respective herbicide applicator should consult with a weed manual before applying any herbicide to the land. 6. Treatment Recommendations 6.1 Pad Surfaces It is recommended that the area directly adjacent to structures be treated with a bare ground herbicide. The bare ground treatment will be applied once a year or as needed to a ten (10) foot perimeter around the structures located on Ursa developments. All other areas are to be spot treated with an appropriate herbicide. 6.2 ROWs and Surrounding Lands Ursa assets should be treated with a selective herbicide appropriate for the species where the noxious weed is found. The appropriate chemical to be applied will be determined by the licensed herbicide applicator. The specific herbicide applied will vary depending on the landowner, time of year and the stage of growth the plant has obtained at the proposed Ursa Operating Company Battlement Mesa PUD Noxious Weed Management Plan 3 treatment date. The Bureau of Land Management (BLM) must be contacted prior to treatment on Federal lands. 6.3 Special Requirements At this point in time there are not any special requirements for Ursa assets or the associated ROWs with regards to management of noxious weeds or other undesirable species. Any and all special requirements will be amended to the document as soon as practicable. 7. Management Strategies 7.1 Prevention Taking preventative measures to abate the spread of noxious weeds is critical for proper land management. Noxious weeds can become established on or near disturbed land very rapidly and have the capacity, capability and potential to spread quickly to other areas. Noxious weed seeds and vegetative matter can be transported by means of animals, vehicles, shoes, and hay to name a few examples of transportation. Operators should be aware of established noxious weed populations and the possible transport mechanisms on their property and surrounding properties. 7.2 Revegetation and Rehabilitation After an area has been successfully eradicated of noxious species, or before establishment has taken place, actions to revegetate the disturbed area should be taken to minimize the chance of noxious weed establishment. If the disturbed land has desired species growing as a result of revegetation efforts, competition with noxious species will be increased. Therefore, the potential and capability of the noxious weed to establish in the disturbed area is limited. Noxious weed management strategies for Ursa will include a monitoring program. Surveys will be carried out between the months of April and October. Noxious weed populations will be monitored at this point through qualitative visual interpretation as well as mapping. 8. Conclusion This noxious weed management plan provides an outline for the treatment and management of noxious weeds. Please refer to Appendix G for the Noxious Weed Summary Documents which provide contact information as well as general information pertaining to Ursa assets. An annual report will be compiled to assess the overall management program. Noxious weed control is critical to guarantee the environment is preserved for future generations to enjoy and utilize. Adhering to this management guide will aid Ursa in managing noxious weeds encountered during active involvement at developed sites. These recommendations are not intended to be used as a definitive guide for noxious weed management. Herbicide recommendations are available from both the state and local governments and/or licensed applicators. Ursa Operating Company Battlement Mesa PUD Noxious Weed Management Plan 4 9.
