Removal of  Delisting #002 in Part 261, Appendix IX

1) Delisting #002 in Appendix IX of Part 261 is amended to read as follows: 

DELISTING #:  002

FACILITY:	NTI, A Division of Colorado Springs Circuits, Inc. (“NTI”)

ADDRESS: 	6035 Galley Road, Colorado Springs, 80915

WASTE: 	Wastewater Treatment Sludge from Electroplating Operations
		EPA hazardous waste # F006, generated after August 20, 1996.

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 had 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  Therefore, NTI’s August 1996 conditional delisting is no longer applicable, and the Commission is removing the delisting.

CONDITIONS: 	This delisting is valid only for the waste stream specified above and referenced in the delisting petition submitted December 5, 1995, under the following conditions:

a.   Changes to Current Processes.

1.  NTI must notify the Division at least 30 days prior to implementing any major change to the electroplating process or the wastewater treatment process. “Major changes”  to the wastewater treatment process includes removing or adding process equipment, using different treatment processes, or utilizing different hazardous chemicals or reagents. “Major changes”  to the electroplating process includes using different chemicals or reagents which contain any hazardous waste constituent listed in 6 CCR 1007-3, Part 261, Appendix VIII. The change must be approved by the Division in a written letter prior to being implemented at the site.

2.  NTI must notify the Hazardous Materials and Waste Management Division, Hazardous Waste Control Section within 15 days after implementing any change to the wastewater treatment process or electroplating process at the facility which causes a significant change in the type or concentration of any hazardous constituents in the waste. “Significant change”  is defined as an increase in the waste concentration of any constituent listed below, greater than the total concentration specified below:

			Constituent	Total Concentration (ppm)
			Arsenic			3
			Chromium		63
			Copper			244,760
			Lead			202
			Mercury		.12
			Nickel			227

“Significant changes” also includes the detection of any additional Part 261, Appendix VIII hazardous constituents not identified above.

3.  In the event that changes to the process occur resulting in any significant changes in the constituents present in the waste, the delisting will not be applicable to such generated waste unless the Director determines that the significant change will not be considered to be harmful to human health and the environment.

b.  Sampling Requirements.

1.  NTI shall conduct quarterly sampling of the delisted waste to monitor any significant change in the type or concentration of any hazardous constituents in the waste.

c.  Storage Requirements.

1.  Delisted waste generated at the facility may not be stored for a period greater than one year.

2.  The maximum total volume or weight of the delisted waste on-site at any one time shall not exceed 40 cubic yards or 28 tons.

3.  The waste must be stored in a container. The container must be capable of being closed. The container must be labelled as containing delisted waste, dated with an accumulation start date, and kept closed at all times except when it is necessary to add or remove waste.

d.  Recordkeeping Requirements.

1.  NTI is required to maintain records of each batch of waste generated including documentation of accumulation dates, amount (volume or weight), and any unusual physical characteristics observed during the generation process (e.g. smell, texture, color).

2.  NTI is required to maintain records of the disposal of all delisted waste which document that the disposal is in accordance with requirements of this delisting.

3.  NTI is required to maintain records of all quarterly sampling conducted under paragraph b of this delisting.

4.  All records must be maintained on site at the facility for a minimum of three years.

e.   Disposal Requirements.

1.  The delisted waste shall be disposed in a landfill meeting the requirements of the Colorado Solid Waste Regulations (6 CCR 1007-2). In addition the landfill must possess the following characteristics:

i.  The landfill must have a designed and constructed liner system.

ii.  The liner system must be constructed of soils or other material which is capable of sustaining an alkaline condition.

2) Add Section 8.68 {Statement of Basis and Purpose for the Rulemaking Hearing of August 19, 2008} to Part 8 of the Regulations as follows:

Statement of Basis and Purpose
Rulemaking Hearing of August 19, 2008

8.68 	Basis and Purpose.

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.
