Standards of Performance for Stationary Gas Turbines

EPA is taking direct final action to revise certain portions of the standards of performance for stationary gas turbines. We are taking direct final action to revise the standards to clarify that EPA is not imposing new requirements for turbines constructed after 1977. Owners and operators of existing and new turbines may use monitoring that meets the pre-existing monitoring requirements. In addition, we have described a number of acceptable compliance monitoring options that owners and operators may elect to use for these units. We see making the amendments by direct final rule as non-controversial and anticipate no adverse comments.
