Office.

(1) Clean Air Scientific Advisory Committee's (CASAC) Air Quality

Models Subcommittee (AQMS): The Air Quality Models Subcommittee will

continue its review of the technical aspects of the Agency's Air

Quality Models with a teleconference meeting on Friday, April 26, 1996

from 11:00 am to 1:00 pm. The AQMS formally began to review air quality

models as a component of the Clean Air Act (CAA) Section 812 Cost-

Benefit Study in a series of public teleconferences on October 1, 1993

and October 21, 1993, with a follow-up review meeting on December 2,

1993 (See 58 FR 49297, September 22, 1993, and 58 FR 60628, November

17, 1993). The Subcommittee is conducting this specialty review on air

quality models on behalf of the Clean Air Act Compliance Analysis

Council (CAACAC) as an activity required under Section 812 of the CAA.

This teleconference meeting is a continuation of the above reviews as

the Agency prepares its final report to Congress. The charge to the

Subcommittee is to review the analytical methodologies, data sources,

implementation, and results of the air quality modeling component of

the Section 812 Retrospective Analysis, and provide advice to the

CAACAC regarding the reasonableness, technical merits, and appropriate

interpretations of the modeling results.

The draft documents that are the subject of this review are

available from the originating EPA office as noted below. There are

eleven (11) draft documents being provided to the AQMS. Nine draft

documents are being provided as background (Items 1 through 9), while

the other two are being submitted for review (Items 10 and 11). These

documents are: Background Documents: (1) The Benefits and Costs of the

Clean Air Act, 1970 to 1990--Report to Congress, Chapter 3: Emissions,

Draft, March 1996; (2) The Benefits and Costs of the Clean Air Act,

1970 to 1990--Report to Congress, Appendix B: Emissions Modeling,

Risk Among the ICRP Publication 66 Regions of the Respiratory Tract,''

dated March 27, 1996) concerning the new ICRP (International Commission

on Radiological Protection) Human Respiratory Tract Model for

Radiological Protection. The new ICRP model was designed to accommodate

the potentially large differences in the doses received and in the

radiation sensitivities of the various tissues comprising the

respiratory tract, as well as being compatible with the ICRP dosimetry

system.

Providing Oral or Written Comments at SAB Meetings

The Science Advisory Board expects that public statements presented

at its meetings will not be repetitive of previously submitted oral or

written statements. In general, opportunities for oral comment at

teleconference meetings will be usually limited to three minutes per

speaker and no more than fifteen minutes total. Written comments (at

least 35 copies) received in the SAB Staff Office sufficiently prior to

a meeting date (usually one week prior to a meeting), may be mailed to

the subcommittee prior to its meeting; comments received too close to

the meeting date will normally be provided to the subcommittee at its

meeting, except for teleconferences, where brief written materials may

be faxed to the participants, with more detailed or lengthy materials

received too close to the teleconference to be mailed to the

subcommittee or committee participants shortly after the

teleconference. Written comments may be provided up until the time of

the meeting.

Dated: March 27, 1996.
