Army Chemical Agent Rocket Incinerator Approval to Dispose of 
Polychlorinated Biphenyls under the Toxic Substances Control Act; 
Notice of Application to Renew, Data Availability, and Modification of 
Existing Approval

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Department of the Army (Army) has applied to renew an 
approval to dispose of polychlorinated biphenyls (PCBs) under the Toxic 
Substances Control Act (TSCA). The renewal would allow the Army to 
continue to incinerate M55 chemical agent rockets containing PCBs using 
the Deactivation Furnace Systems (DFS). This action announces: EPA's 
consideration of the Army's application, the availability of trial burn 
data that will inform EPA's consideration, and the modification of the 
public participation condition of the Army's existing approval. EPA is 
requesting comments on the renewal application and trial burn data.

DATES: Comments must be received on or before June 11, 2007].

instance, because of the enormity of the volume of data, EPA has posted 
a summary (entitled ``Executive Summary'') of the trial burn report 
from each facility. If the interested party needs more information than 
is found in the Executive Summary, complete trial burn data is 
available on compact disc (CD). To obtain a CD, please contact the

    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.
    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 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.
