These documents provide guidelines for the preparation of attachments for the Oil and Gas Location Assessment, Form 2A. Each document includes the following information for the attachment:

  • Definition: definition from COGCC Rule 100 Series, if applicable (only a small number of attachments are defined by a 100 Series rule)
  • Rule/Policy Citation: language from the COGCC rule or policy that serves as the basis for the attachment requirements
  • Purpose: description of the purpose the attachment serves as part of the permit application
  • Requirements: identification of instances in which the attachment is required, followed by a list of minimum requirements for the attachment itself
  • Common Errors and Issues: a list of the most common errors and issues that COGCC staff encounters with operators' submittals of the attachment
  • Notes: any additional information relating to the attachment, including reference to other COGCC guidance documents

NOTE

Every well is unique, with a specific set of parameters that dictate the regulatory requirements. This means it is not possible to create a "one-size-fits-all" guide for the preparation of the attachments for a Form 2A. This document is not a comprehensive list of all potential requirements and errors; it focuses on the more common issues and errors.


TIP

If you are preparing the attachments for a Form 2A for a well with circumstances that you have never encountered before, contact COGCC staff to discuss the possible issues related to the attachment requirements prior to submittal.
