The EPD is proposing to revise GRAQC Rule 391-3-1-.03(8)(c) by removing Paragraph 16, Additional Provisions for PM2.5 Non-Attainment Areas. This regulatory action is a result of the Atlanta metropolitan statistical area (MSA) being redesignated to attainment for the 1997 fine particulate matter (i.e., PM2.5) NAAQS in 2016. For industrial facilities in the Atlanta MSA, which extends to a total of 20 counties, this SIP modification could be beneficial if the facility emits PM2.5, sulfur dioxide (SO2), or nitrogen oxides (NOx) emissions above 100 tons per year (tpy). In those instances, the current regulation requires a facility to evaluate potential non-attainment New Source Review (NNSR) permitting requirements. With the potential removal of Paragraph 16, permitting for those large facilities will no longer need to evaluate NNSR permitting requirements for direct PM2.5. This proposed regulation change will not impact facility requirements to evaluate potential ozone NNSR permitting requirements.
EPD is currently accepting comments from the public regarding this proposed regulation change. The rule amendments are scheduled to be considered for adoption into the regulations during a June 2017 board meeting. For further information pertaining to the proposed amendments, click here.
