At any given time, the CGA Best Practices Committee will have 10-15 potential new practices under committee review.  In addition, the committee receives approximately 10 new practice proposals per year. 

Prior to approval, each new practice must pass through the "Best Practices Committee" review and approval process.  By the time a new practice arrives at a meeting for final approval, the wording has often been under review for over one year; and the wording has been reviewed closely by fifteen stakeholder groups, their respective companies/trade associations, and many of the 1,200 CGA members.  Each approved new practice and/or practice revision must then receive consensus approval at a Best Practices Meeting and final approval by the CGA Board of Directors.   

As a result, any best practices endorsed by the CGA come with consensus support from experts representing the following stakeholder groups:   Excavator, Locator, Road Builders, Electric, Telecommunications, Oil, Gas, Railroad, Water, One Call, Public Works, Equipment Manufacturing, State Regulators, Insurance, Engineering Design and Emergency Services.
