2/1/2018	Amended permits were issued for 37-1, 37-2, 37-3 & 37-4 to correct the emission point characteristics and to remove the isocyanate references in the permits for 37-1 and 37-3. These were the last of the requirements from the 8/24/17 inspection.	GLENN CARPER

12/4/2017	The facility has submitted permit amendment requests for 37-1, 37-2, 37-3 & 37-4 to correct the EP characteristics and to remove the references to isocyanate in permits for 37-1 and 37-3.	GLENN CARPER
12/4/2017	Van Diest has achieved compliance with the pressure drop range requirements for DF-2, DF-6 and EPNF through a combination of operational changes and use of more resistive filter material. Since obtaining the more resistive filter material, DF-7 has not operated. Compliance will be determined during its next production run.	GLENN CARPER

Compliance for all other deficiencies noted during the 7/12 & 8/24/17 inspection has already been achieved.	GLENN CARPER
10/25/2017	Permit 12-A-496-S2 for EPNF, permit 14-A-533-S2 for B45-2, permit 14-A-534-S2 for B46-1 and permit 17-A-008-S1 for DCL were issued on 10/25/17 to correct the emission point characteristics. The facility still needs to amend the permits for 37-1, 37-2, 37-3 & 37-4 to correct the EP characteristics and to remove the references to isocyanate in permits for 37-1 and 37-3.	GLENN CARPER
10/25/2017	Permit 16-A-302-S1 for DF6-EL was issued on 10/25/17 to correct the equipment count.	GLENN CARPER
10/25/2017	Van Diest will attempt to comply with the pressure drop limits in the permits for DF-2, DF-6, DF-7 & EPNF. Compliance already achieved for DF-2 & EPNF. Will try more resistive filter material to achieve compliance for DF-6 & EPNF.	GLENN CARPER

10/23/2017	E-mail update from the industry was received on 10/23/17. Permit amendment requests have been made to reduce the lower pressure drop range requirement for DF-2, DF-6, DF-7 & ECNF. Mr. Piaszynski stated that operation changes were made for all four BF with positive results for DF-2 & ECNF. Operational changes were not effective for DF-6 & DF-7. More resistive filter material has been ordered in an attempt to increase the pressure drop. A permit amendment has been requested to correct the number of connectors listed in the permit for DF6-EL. Permit amendment requests have also been made to correct the emission point characteristics for 8 EPs.	GLENN CARPER
9/26/2017	The 9/5/17 LNC required rescission of the permit for DF5, the Test Plant, (permit no. 95-A-400-S2). Mr. Piaszynski did some checking and determined that there had been an older permit for an EP called the "Test Plant". That permit (88-A064-S2) was rescinded in 2002. The two test plants were confused with each other during preparation for this inspection. The permit for DF5, the current Test Plant, (95-A-400-S2) is still active and should not be rescinded.	GLENN CARPER
9/25/2017	The stack for ECW2 was misidentified during the inspection. It does in fact comply with the listed permit requirements. Permit amendments will be sought for the remaining stacks to correct the emission point characteristics.	GLENN CARPER
9/25/2017	The number of connectors for DF6-EL will be counted and a permit amendment will be sought to list the correct number of connectors.	GLENN CARPER
9/25/2017	Permit amendments will be sought for DF2, DF6 & DF7 to adjust the lower limit of the pressure drop range. Operational measures will be tried for ECNF to achieve compliance with the pressure drop range.	GLENN CARPER
9/25/2017	E-mail copy of response from the industry was received on 9/21/17. The response adequately addressed all issues. Permit amendments will be sought for DF2, DF6 & DF7 to adjust the lower limit of the pressure drop range. Operational measures will be tried for ECNF to achieve compliance with the pressure drop range. The number of connectors for DF6-EL will be counted and a permit amendment will be sought to list the correct number of connectors. The stack for ECW2 was misidentified during the inspection. It does in fact comply with the listed permit requirements. Permit amendments will be sought for the remaining stacks to correct the emission point characteristics.	GLENN CARPER

8/31/2017	First inspection date should have been 7/12/17.	GLENN CARPER
8/31/2017	Air quality inspection conducted on 7/17 and 8/24/17. The following deficiencies were documented: 1) four EPs (DF2, DF6, DF7 & ECNF) could not meet the lower limit of the pressure drop range in the permits, 2) one EP (DF6-EL) exceeded the number of connectors allowed by the permit, and 3) stacks for nine EPs (ECW2, 37-1, 37-2, 37-3, 37-4, ECNF, B45-2, B46-1 & DCL) did not match the EP characteristics in their permits. Issued LNC and required written response (Plan of Action) within 15 days.	GLENN CARPER
