On May 4th, 2016, the South Coast Air Quality Management District (SCAQMD) released Draft Proposed Amended Best Available Control Technology (BACT) Guidelines. SCAQMD requires that emission sources with potential to emit at least one pound per day of any regulated pollutant implement BACT, and Regulation XIII requires SCAQMD to periodically publish BACT Guidelines that establish the procedures and BACT requirements for commonly permitted equipment. The BACT Guidelines are broken up into the following sections:
The largest change of the Draft Proposed Amended BACT Guidelines is the addition of Parts E and F, which provide BACT procedures and BACT determinations. The draft text of Part E is available for review at this time; however, Part F, the GHG BACT determination section, is still under development.
The proposed amendments also include changes to Parts A through D. Along with administrative changes, the proposed amendments include revisions to certain source types within the Major Source and Minor Source BACT Guidelines. However, the revised BACT Guidelines do not include any emission limits that go above and beyond current SCAQMD rules. Instead, the proposed revisions are primarily aimed towards aligning the BACT Guidelines with current Rules. Proposed amendments to Part B, LAER/BACT Determinations for Major Polluting Facilities, include changes to the following source categories:
Proposed amendments to Part D, BACT Guidelines for Non-Major Polluting Facilities, include changes to the following source categories.
