Redbud will be used for 2018 Emission Inventory Reporting

DEQ is currently working to replace Redbud, our in-house tool for reporting emissions inventories online, with the State and Local Emissions Inventory System (SLEIS) from Windsor Solutions. Due to the time needed to complete customization, implementation, testing and training on SLEIS, the Air Quality Division has determined that Redbud will continue to be used for the submission of 2018 inventories, which are due by April 1, 2019. Updated October 25, 2018

Revisions to Test Methods, Performance Specifications, and Testing Regulations for Air Emission Sources


Final Rule Signed August 5, 2016: The final "revisions" rule allows source owners and operators of stationary spark ignition internal combustion engines to continue to use Methods 18 and 320 and ASTM D6348-03 to measure VOC but requires reporting of all QA/QC data. See Subpart JJJJ, Section 60.4245(d) and Table 2.

    For Method 18, results from Sections 8.4 and must be reported.

    For Method 320, results from Sections 8.6.2, 9.0, and 13.0 must be reported.

    For ASTM D6348-03, results of all QA/QC procedures in Annexes 1-7 must be reported.

In the preamble to the final "revisions" rule, EPA states that it will revisit the above decision and make a subsequent determination of the appropriateness of the use of Method 320 and/or ASTM D6348 during the first risk and technology review evaluation for stationary spark ignition internal combustion engines.
