00-3217. Notice of Availability: Announcing the availability of a new draft guidance document entitled Screening Level Ecological Risk Assessment Protocol for Hazardous Waste Combustion Facilities

AGENCY:

Environmental Protection Agency.

ACTION:

Notice of document availability and public comment period.

SUMMARY:

The Environmental Protection Agency (“EPA” or “the Agency”) is providing notice that the following draft guidance document Screening Level Ecological Risk Assessment Protocol for Hazardous Waste Combustion Facilities (Peer Review Draft) is available and an 180-day public review period of the document will begin today.

This document contains the Office of Solid Waste's recommended approach for conducting site-specific ecological risk assessments on hazardous waste combustors regulated under the RCRA program. The document includes specific parameters, pathways and algorithms to evaluate both direct and indirect risks to ecological receptors. The goal of this guidance document is to develop a consistent and credible methodology for conducting ecological risk assessments at hazardous waste combustion facilities. The results of the risk assessments will give an understanding of the potential ecological risks associated with emissions from those facilities.

On October 30, 1998, EPA announced in the Federal Register (FR Doc. 98-29157) the availability of this documents' companion document, Human Health Risk Assessment Protocol for Hazardous Waste Combustion Facilities (Peer Review Draft—EPA530-D-98-001A, B & C). OSW recommends that RCRA permitting authorities consider these documents together when conducting risk assessments on hazardous waste combustor emissions. The results of these risk assessments can provide a basis for risk management decisions in the permitting of hazardous waste combustors and help to ensure that the operation of hazardous waste combustion facilities will be protective of human health and the environment.

This document has undergone extensive internal Agency review. It is Agency policy that documents such as this be subject to peer review as well. EPA expects to have the document reviewed by a group of independent scientists in the future. Information regarding the peer review process will be published in a Federal Register notice closer to the date of the review.

All public comments should be received by August 9, 2000, to be considered by the Agency. The public comments will be for the Agency's evaluation only and are not intended to be part of the peer review process. To ensure an efficient public comment review and resolution process, EPA recommends that the comments be supplied in the following format. All comments should be individually identified and a proposed resolution (or action) be recommended. In addition, any supporting information or reference materials which corroborate the comment and or proposed resolution should be furnished as well. All information supplied should be in English or accompanied by an English translation. All comments received from both the public and the peer review will be considered during finalization of this guidance document.

DATES:

Public comments on the document Screening Level Ecological Risk Assessment Protocol for Hazardous Waste Combustion Facilities should be received by the docket no later than August 9, 2000.
