On February 28, 2003 AGA submitted comments to EPA supporting detailed INGAA Comments on National Emission Standards for Hazardous Air Pollutants for Stationary Combustion Turbines (“Proposed Turbine MACT Rule”). These comments note that AGA supports the detailed technical comments dated February 28, 2003 that INGAA filed in this docket on EPA’s Proposed Turbine MACT Rule. In particular, we are pleased that EPA is proposing no emission requirements for new turbines, reconstructed turbines, and existing diffusion flame turbines. This will help limit the burdens on natural gas pipeline and utility compressor turbines needed to deliver natural gas to customers efficiently and at reasonable cost. The proposal regarding new turbines will also help encourage the installation of new clean natural gas turbines as distributed energy. However we share INGAA’s concerns regarding the proposed requirements for existing lean premix turbines, and we agree that lean premix turbines should be divided into two subcategories for large and small units.
