6 Colo. Code Regs. § 1007-3-8.68
This amendment to 6 CCR 1007-3, Part 261, Appendix IX is made pursuant to the authority granted to the Solid and Hazardous Waste Commission in § 25-15-302(2), C.R.S.
Removal of Delisting #002 in Part 261, Appendix IX
The Solid and Hazardous Waste Commission is hereby removing the conditional delisting granted to NTI, a division of Colorado Springs Circuits, Inc. ("NTI"), for its facility located at 6035 Galley Road in Colorado Springs, Colorado (the "Facility").
NTI was granted a conditional delisting by the Commission on August 20, 1996 for wastewater treatment sludge (F006 hazardous waste) generated from electroplating operations at the Facility.
The delisting was granted under conditions that specified sampling, storage, recordkeeping and disposal requirements for the delisted sludge. The conditional delisting of the F006 waste also prohibited any major changes to the electroplating process or wastewater treatment process at the Facility without prior notification, evaluation, and approval by the Division.
In January of 2000, Dynamic Details, Inc. ("DDI"), formally known as NTI, announced its plans to consolidate its pre-production manufacturing operations located at the Facility into its Dallas, Texas operation, which would result in the complete closure of the Colorado Springs facility.
On June 20, 2000, the Division received formal notice indicating that DDI officially ceased operations at the Facility on December 31, 1999, and had completed all closure activities at the Facility as of May 18, 2000. Therefore, NTI's August 1996 conditional delisting is no longer applicable, and the Commission is removing the delisting.
Removal of Delisting #7 in Part 261, Appendix IX
The Solid and Hazardous Waste Commission is hereby removing the conditional delisting granted to the Golden Aluminum, Inc. ("Golden Aluminum") facility in Fort Lupton, Colorado (the "Facility").
Golden Aluminum was granted a conditional delisting by the Commission on October 18, 2005 for wastewater treatment sludge (F019 hazardous waste) generated from aluminum cleaning and conversion coating operations at the Facility.
The delisting was granted under conditions that specified disposal, recordkeeping, and storage requirements for the delisted sludge. The conditional delisting of the F019 waste also prohibited any major changes to the chemical conversion coating process or wastewater treatment process without prior notification, evaluation, and approval by the Division.
On February 12, 2008, the Division received notification from Golden Aluminum indicating that the Facility would be converting its titanium conversion coating process to a chrome conversion coating process effective February 18, 2008.
Delisting determinations are made on a case-by-case basis with respect to a specific waste generation process. Golden Aluminum's change to a new chromate conversion coating process using hexavalent chromium is a significant change from the titanium conversion coating process described in the Facility's April 8, 2005 delisting petition.
Golden Aluminum's 2005 delisting no longer covers the wastewater treatment sludge generated at the Facility, and the Facility was notified by the Division on March 24, 2008 that wastewater treatment sludge generated from the new chromate conversion coating process at the Facility must be collected and managed as a hazardous waste with the waste code of F019.
