Approved Section 17 – Oil and Gas Regulations Attachment A

17.0. – OIL AND GAS FACILITIES

17.1. – Intent and Purpose.

A. Intent. The intent of this section of the Land Use Code is to establish a regulatory framework for new oil and gas facilities (O&GFs) to be located in the unincorporated areas of Larimer County in a manner that acknowledges private property rights and protects the public health, safety and general welfare, protects environment and wildlife, and minimizes adverse impacts.

B. Authority: C.R.S. 29-20-104-(1) provides the County authority to regulate and review applications pertaining to the surface development of O&GFs.

C. Purpose: These regulations are necessary to:

1. Ensure a comprehensive land use process and transparent public process for the development of new O&GFs, in the unincorporated areas of the County.

2. Provide for the managed development, installation, maintenance, modification, reclamation, and removal of O&GFs, while acknowledging the interests of oil and gas developers and operators, or mineral interest owners.

3. Minimize to the maximum extent possible the nuisance effects of O&GFs through the application of best available techniques and technologies.

4. Promote and protect the public health, safety, and welfare, and protect the environment and wildlife by minimizing the adverse impacts of O&GFs.

5. Maximize protection of natural and cultural resources and public facilities.

6. Encourage O&GF’s to strategically locate where adverse impacts from such operations can be avoided.

7. Minimize and mitigate the extent and severity of adverse impacts that cannot be avoided. 8. Confirm the financial, indemnification and insurance capacities of the oil and gas developer/operator to ensure timely and effective construction, production, removal and reclamation of O&GFs and infrastructure.

D. Applicability: These regulations shall apply to all new (greenfield) O&GFs, to be constructed on any property in all zoning districts in the unincorporated portions of Larimer County.

E. Severability: If any section, clause, provision, or portion of these regulations should be found to be unconstitutional or otherwise invalid by a court of competent jurisdiction, the remainder of the regulations in this section shall not be affected thereby and is hereby declared to be necessary for the public health, safety and welfare.

17.2. – Review Procedures and Required Permits.

A. General Requirements. No person, firm or corporation shall establish, construct, or build a new O&GF, without first having obtained required land use approval(s) and permits as required by this Code. Applications to the County for new O&GFs, may be submitted simultaneously with the Colorado Oil and Gas Conservation Commission (COGCC) permitting process.

B. County Review Process: All new O&GFs, in the unincorporated portions of Larimer County shall require approval of a Special Review application for the proposed facility as set forth in Section 4.5 of this Code. Application and submittal requirements for O&GFs are specified in the following Community Development Department application handouts:

1. Sketch Plan Review Application and Submittal Requirements for Oil and Gas Facilities. 2. Neighborhood Meeting Submittal Requirements and Guidelines for Oil and Gas Facilities. 3. Special Review Application and Submittal Requirements for Oil and Gas Facilities.

E. Non-County Permits: County approval of an O&GF shall not relieve the landowner or applicant of the responsibility for securing other permits or approvals required by any other applicable County Departments, local fire district, municipalities, or other applicable publicagencies.

F. Technical Expert Review: Applications for O&GFs may involve complex technical issues that require review and input that is beyond the expertise of County staff. If such a situation arises, the Community Development Director may commission a third-party review of the relevant subject matter and require the applicant to pay reasonable costs for the third-party review. Selection of a third-party expert(s) to review portions the proposal will be at the discretion of the County.
