What Should I Consider as I Prepare My Comments for EPA? 1. Submitting CBI. Do not submit this information to EPA through regulations.gov or e-mail. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then identify electronically within the disk or CD-ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. 2. Tips for preparing your comments. When submitting comments, remember to: i. Identify the document by docket ID number and other identifying information (subject heading, Federal Register date and page number). ii. Follow directions. The Agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number. iii. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes. VerDate Aug<31>2005 17:34 May 24, 2007 Jkt 211001 iv. Describe any assumptions and provide any technical information and/ or data that you used. v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced. vi. Provide specific examples to illustrate your concerns and suggest alternatives. vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats. viii. Make sure to submit your comments by the comment period deadline identified. II. What Action is the Agency Taking? A. Background In 2002, EPA issued a PCB disposal approval under TSCA section 6(e) and 40 CFR 761.70(d) to the Army to allow for the incineration of M55 chemical agent rockets containing PCBs using Deactivation Furnace Systems (DFS). The existing approval is included in the docket for this notice. The approval allows for the disposal to occur at four separate facilities: Anniston Chemical Agent Disposal Facility, Anniston Army Depot, Anniston, Alabama (ANCDF); Pine Bluff Chemical Agent Disposal Facility, Pine Bluff Arsenal, Pine Bluff, Arkansas (PBCDF); Tooele Chemical Agent Disposal Facility, Deseret Chemical Depot, Tooele, Utah (TOCDF); and Umatilla Chemical Agent Disposal Facility, Umatilla Chemical Depot, near Hermiston, Oregon (UMCDF). The Army has now applied to renew that approval, which is currently set to expire July 6, 2007. The Army’s renewal application only applies to PBCDF and UMCDF; the other two facilities have completed operations. B. Application for Renewal EPA is considering the Army’s request for renewal. The renewal would allow the Army to continue to incinerate M55 chemical agent rockets containing PCBs using DFS at the remaining two sites. Based on the trial burn results, EPA believes the conditions in the current TSCA approval are necessary and adequate to ensure proper disposal of PCBs in compliance with TSCA. However, both PBCDF and UMCDF are currently operating under Resource Conservation and Recovery Act (RCRA) permits as well as the existing PCB approval. These RCRA permits impose several of the same operating conditions as are required by the current TSCA approval. Thus, in order to coordinate the requirements of the two programs, EPA does not plan to include the duplicative conditions in the renewed PO 00000 Frm 00026 Fmt 4703 Sfmt 4703 TCSA approval. EPA intends for the renewal to only retain the operating conditions from the current TSCA approval that are more stringent than those provided in the RCRA permits. These more stringent conditions, combined with the condition that the facilities maintain valid RCRA permits, will ensure proper disposal of PCBs in compliance with TSCA. For example, EPA plans to retain a target value for the secondary combustor operating temperature based on conditions during the trial burn. In addition, the carbon monoxide concentration in the flue gas that triggers the automatic waste feed cutoff (AWFCO) would be 100 parts per million based on real time, with a 5– minute delay. C. Availability of Trial Burn Data This action also announces the availability of trial burn data from PBCDF and UMCDF. The current approval required certain sampling for PCBs at each DFS unit: 1. Stack sampling for PCBs. 2. Sampling of kiln/HDC (heated discharge conveyor) residue. 3. Cyclone residue. 4. Scrubber brine for PCB analysis. The purpose of the trial burns was to demonstrate whether the DFS units meet the PCB incinerator performance standards. These results showed that the standards were met, and the data are now available. D. Approval Modification Condition 1.d.(3) of the existing approval, provides that: ‘‘EPA will hold a public meeting in each community after the trial burn data in each respective facility becomes available.’’ (A copy of Condition 1.d.(3) is available in the docket for this document.) Effective at the time of publication of this notice, EPA is hereby modifying the existing approval to remove that condition for the remainder of the approval. Meetings were conducted before and after-trial-burn data became available at ANCDF and TOCDF, but participation was very limited at the post-trial-burn meetings. No members of the public appeared at meetings previously held at PBCDF and UMCDF. Based on the lack of public participation, EPA is changing the public participation process to include a broader audience and a 15–day opportunity for comment. Trial burn data will be available to the public through the docket and in lieu of conducting additional public meetings at PBCDF and UMCDF, EPA is allowing for the submission of comments, in written or electronic format.

II. What Action is the Agency Taking?

A. Background

    In 2002, EPA issued a PCB disposal approval under TSCA section 6(e) 
and 40 CFR 761.70(d) to the Army to allow for the incineration of M55 
chemical agent rockets containing PCBs using Deactivation Furnace 
Systems (DFS). The existing approval is included in the docket for this 
notice. The approval allows for the disposal to occur at four separate 
facilities: Anniston Chemical Agent Disposal Facility, Anniston Army 
Depot, Anniston, Alabama (ANCDF); Pine Bluff Chemical Agent Disposal 
Facility, Pine Bluff Arsenal, Pine Bluff, Arkansas (PBCDF); Tooele 
Chemical Agent Disposal Facility, Deseret Chemical Depot, Tooele, Utah 
(TOCDF); and Umatilla Chemical Agent Disposal Facility, Umatilla 
Chemical Depot, near Hermiston, Oregon (UMCDF). The Army has now 
applied to renew that approval, which is currently set to expire July 
6, 2007. The Army's renewal application only applies to PBCDF and 
UMCDF; the other two facilities have completed operations.

B. Application for Renewal

    EPA is considering the Army's request for renewal. The renewal 
would allow the Army to continue to incinerate M55 chemical agent 
rockets containing PCBs using DFS at the remaining two sites. Based on 
the trial burn results, EPA believes the conditions in the current TSCA 
approval are necessary and adequate to ensure proper disposal of PCBs 
in compliance with TSCA. However, both PBCDF and UMCDF are currently 
operating under Resource Conservation and Recovery Act (RCRA) permits 
as well as the existing PCB approval. These RCRA permits impose several 
of the same operating conditions as are required by the current TSCA 
approval. Thus, in order to coordinate the requirements of the two 
programs, EPA does not plan to include the duplicative conditions in 
the renewed TCSA approval. EPA intends for the renewal to only retain 
the operating conditions from the current TSCA approval that are more 
stringent than those provided in the RCRA permits. These more stringent 
conditions, combined with the condition that the facilities maintain 
valid RCRA permits, will ensure proper disposal of PCBs in compliance 
with TSCA. For example, EPA plans to retain a target value for the 
secondary combustor operating temperature based on conditions during 
the trial burn. In addition, the carbon monoxide concentration in the 
flue gas that triggers the automatic waste feed cutoff (AWFCO) would be 
100 parts per million based on real time, with a 5-minute delay.

C. Availability of Trial Burn Data

    This action also announces the availability of trial burn data from 
PBCDF and UMCDF. The current approval required certain sampling for 
PCBs at each DFS unit:
    1. Stack sampling for PCBs.
    2. Sampling of kiln/HDC (heated discharge conveyor) residue.
    3. Cyclone residue.
    4. Scrubber brine for PCB analysis.
    The purpose of the trial burns was to demonstrate whether the DFS 
units meet the PCB incinerator performance standards. These results 
showed that the standards were met, and the data are now available.

D. Approval Modification

    Condition 1.d.(3) of the existing approval, provides that: ``EPA 
will hold a public meeting in each community after the trial burn data 
in each respective facility becomes available.'' (A copy of Condition 
1.d.(3) is available in the docket for this document.) Effective at the 
time of publication of this notice, EPA is hereby modifying the 
existing approval to remove that condition for the remainder of the 
approval. Meetings were conducted before and after-trial-burn data 
became available at ANCDF and TOCDF, but participation was very limited 
at the post-trial-burn meetings. No members of the public appeared at 
meetings previously held at PBCDF and UMCDF. Based on the lack of 
public participation, EPA is changing the public participation process 
to include a broader audience and a 15-day opportunity for comment. 
Trial burn data will be available to the public through the docket and 
in lieu of conducting additional public meetings at PBCDF and UMCDF, 
EPA is allowing for the submission of comments, in written or 
electronic format.
