Volkswagen Settlement


DEQ has released a proposed Volkswagen Beneficiary Mitigation Plan (BMP). The BMP is a high-level plan describing the State's intentions for utilizing Oklahoma's funding allocation from the Volkswagen Environmental Mitigation Trust.

A public meeting was held at DEQ headquarters on May 8, 2018 during which DEQ presented on the BMP and comments were received. The meeting included an informational presentation by DEQ staff, an opportunity for oral and/or written public comments, and a presentation on the anticipated future outlook.

Written Comments on the Proposed BMP will be accepted until May 24, 2018. It is requested that comment topics be limited to the BMP. For the draft plan, how to submit comments, and more, please visit our VW page. Updated May 15, 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.
