nondiscriminatory discipline. If an

employer/owner/operator provides

employees with appropriate PPE,

training and supervision per the

specifications of the WPS, there should

not arise an occasion on which the

employer/owner/operator would be

subject to a WPS/PPE enforcement

action due to the individual decision of

an agricultural employee not to use the

PPE.

Enforcement officials will consider

the facts of a case before determining

how to respond to any WPS violation,

consistent with the 10 factors identified

in the Agency’s February 1995 summary

WPS enforcement guidance. EPA

recommends that accountability for

compliance be decided on a common

sense basis, and that the totality of the

circumstances be considered in each

case, including enforcement actions in

response to PPE violations.

The Use of the Benchmark Dose

Approach in Health Risk Assessment

AGENCY: Environmental Protection

Agency.

ACTION: Notice of Availability.

SUMMARY: This notice announces the

availability of a report titled The Use of

the Benchmark Dose Approach in

Health Risk Assessment (EPA/630/R–

94/007). This report was developed to

serve as a background document for

discussing benchmark dose applications

to noncancer risk assessment.

ADDRESSES: To obtain a single copy of

the report, interested parties should

contact the ORD Publications Office,

Agency, 26 West Martin Luther King

Drive, Cincinnati, OH 45268, Tel: (513)

SUPPLEMENTARY INFORMATION: For almost

10 years, scientists have been studying

the benchmark dose (BMD) as a

promising technique for the quantitative

assessment of noncancer health effects.

The information presented in this report

is one step in developing the basis for

an EPA consensus on the role of

benchmark methods in the quantitative

assessment of noncancer health risk.

The report presents a basic overview of

the benchmark method, which may

provide an additional quantitative

approach to current EPA practice.

The document focuses especially on

critical decisions that must be made in

deriving a BMD and applying the BMD

in risk assessment. Major decisions in

using the BMD are explained, and the

sensitivity of the final result to each

assumption is evaluated. The document

also identifies many unresolved issues

in benchmark dose application and

identifies research that may help resolve

some of these issues.

Assistant Administrator for Research and

Report on the Technical Review

Workshop on the Reference Dose for

Aroclor 1016

AGENCY: Environmental Protection

Agency.

ACTION: Notice of availability.

SUMMARY: This notice announces the

availability of a report titled Technical

Review Workshop on the Reference

Dose for Aroclor 1016 (EPA/630/R–94/

006). This report compiles discussions

from a technical review workshop on

the reference dose for Aroclor 1016,

which was held in Washington, DC, on

May 24–25, 1994.

SUPPLEMENTARY INFORMATION: This

report includes information and

materials from a technical review

workshop organized by the U.S.

Environmental Protection Agency’s Risk

Assessment Forum for the Agency’s

Reference Dose/Reference Concentration

(RfD/RfC) Work Group. The meeting

was held in Washington, DC, at the

Barcelo Washington Hotel on May 24–

25, 1994 (59 FR 23202).

EPA convened a balanced panel of

experts from the fields of qualitative and

quantitative effects of PCBs in humans

and animals, perinatal toxicity,

neurobehavioral effects, and hazard and

risk evaluation for data on health effects

other than cancer. EPA sought

comments from these experts on the

IRIS entry and related scientific sources.

Reviewers at the workshop were asked

to evaluate whether the reference dose

fully considered available data and if

scientifically responsible data analyses

were clearly articulated in the IRIS data

base entry. Reviewers approved some

features of the IRIS entry, and

recommended additional review and

analysis for others.

This report collects workshop papers,

including summary statements prepared

by the chairperson for each workshop

topic. Workshop participants

contributed useful recommendations for

the Agency’s Reference Dose/Reference

Concentration Work Group to consider

in re-evaluating the RfD entry on IRIS.

Dated: March 24, 1995.
