Start Preamble


Environmental Protection Agency (EPA).




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.

A. Does this Action Apply to Me?

Potentially affected entities may include, but are not limited to:

  • Department of the Army (NAICS code 928110).
  • Residents or homeowners located near the affected incinerators.

This list is not intended to be exhaustive, but rather provides a guide for readers regarding entities likely to be affected by this action. Other types of entities not listed in this unit could also be affected. The North American Industrial Classification System (NAICS) codes have been provided to assist you and others in determining whether this action might apply to certain entities.

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.

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.
