Make sure to submit your comments by the comment period deadline identified. II. Background EPA is currently in the process of determining whether or not lead-based paint hazards are created by RRP activities in P&CBs, as required under TSCA, Subtitle IV (15 U.S.C. 2681 et seq.). For those renovation activities in P&CBs that create lead-based paint hazards, TSCA directs EPA to address the hazards through regulation.

This Framework document described, in general terms, how EPA could identify and evaluate hazards in P&CBs. The current document, entitled ‘‘Approach for Estimating Exposures and Incremental Health Effects from Lead Due to Renovation, Repair, and Painting Activities in Public and Commercial Buildings’’ (Ref. 3) describes how EPA is modeling the potential overall magnitude and distribution of renovation-related health effects due to lead exposure from a renovation in a P&CB, taking into account background lead levels when no such renovation exposure occurs.

Exposures from renovation activities that disturb lead-based paint are connected to subsequent health effects in children and adults through modeling. Separate Monte-Carlo based models were constructed for the analysis of exterior renovations of P&CBs and interior renovations of P&CBs. The Monte Carlo analysis is designed to capture potential population-level variability within each exposure scenario and, as such, approximates the potential distribution of effects to the part of the U.S. population who would fall within any scenario. However, the results presented in the Approach are not representative of an overall distribution of the entire U.S. population. All scenarios are not equally likely, and in fact some scenarios may be very unlikely to occur. In the future, EPA plans to estimate how many people may be reasonably expected to be exposed in different scenarios. After further analysis, the full results of the Approach, along with information about how often any scenario is expected to actually occur, will be used to consider whether or not renovation activities in P&CBs create hazards and, if so, what mitigation measures may be appropriate. EPA plans to consider renovation-related dust loadings, blood lead, and health effect changes across exposure scenarios in order to evaluate whether a hazard occurs. A detailed discussion of the additional analyses and considerations that would inform EPA’s process of making a hazard finding, or a finding of no hazard, are contained in the Approach. By itself, the Approach methodology cannot be used to determine whether hazards exist from P&CB renovations. EPA will need to conduct additional analyses and make certain science policy decisions in order to determine whether such hazards exist. EPA’s Office of Pollution Prevention and Toxics (OPPT) has identified the Approach as an influential product and according to EPA peer review guidance is conducting an external peer review of that document, supplemental files, appendices (Ref. 4), and attendant models used for exposure scenarios. The external peer reviewers will assess the accuracy and content of the Approach, ensuring that the Approach and initial results are scientifically sound. The external peer review will also address the supplemental documents, which include detailed appendices for the Approach and a supplementary report relating lead exposure to Cardiovascular E:\FR\FM\06AUN1.SGM 06AUN1 45798 Federal Register / Vol. 79, No. 151 / Wednesday, August 6, 2014 / Notices Disease (CVD) mortality and proposing an approach to quantify adult health benefits from a reduction in lead (Pb) exposure for CVD mortality, entitled ‘‘Developing a Concentration-Response Function for Pb Exposure and Cardiovascular Disease-Related Mortality’’ (Ref. 5).

II. Background

    EPA is currently in the process of determining whether or not lead-
based paint hazards are created by RRP activities in P&CBs, as required 
under TSCA, Subtitle IV (15 U.S.C. 2681 et seq.). For those renovation 
activities in P&CBs that create lead-based paint hazards, TSCA directs 
EPA to address the hazards through regulation.
    EPA recently published in the Federal Register of May 30, 2014 
(Ref. 1) a document for public comment, entitled ``Framework for 
Identifying and Evaluating Lead-Based Paint Hazards from Renovation, 
Repair, and Painting Activities in Public and Commercial Buildings'' 
(Ref. 2). This Framework document described, in general terms, how EPA 
could identify and evaluate hazards in P&CBs.
    The current document, entitled ``Approach for Estimating Exposures 
and Incremental Health Effects from Lead Due to Renovation, Repair, and 
Painting Activities in Public and Commercial Buildings'' (Ref. 3) 
describes how EPA is modeling the potential overall magnitude and 
distribution of renovation-related health effects due to lead exposure 
from a renovation in a P&CB, taking into account background lead levels 
when no such renovation exposure occurs. Based on information developed 
through the Approach, renovation-related health effects will be 
estimated as the difference between total health effects (background 
plus renovation-related) and background. Exposures from renovation 
activities that disturb lead-based paint are connected to subsequent 
health effects in children and adults through modeling. Separate Monte-
Carlo based models were constructed for the analysis of exterior 
renovations of P&CBs and interior renovations of P&CBs.
    The Monte Carlo analysis is designed to capture potential 
population-level variability within each exposure scenario and, as 
such, approximates the potential distribution of effects to the part of 
the U.S. population who would fall within any scenario. However, the 
results presented in the Approach are not representative of an overall 
distribution of the entire U.S. population. All scenarios are not 
equally likely, and in fact some scenarios may be very unlikely to 
occur. In the future, EPA plans to estimate how many people may be 
reasonably expected to be exposed in different scenarios.
    After further analysis, the full results of the Approach, along 
with information about how often any scenario is expected to actually 
occur, will be used to consider whether or not renovation activities in 
P&CBs create hazards and, if so, what mitigation measures may be 
appropriate. EPA plans to consider renovation-related dust loadings, 
blood lead, and health effect changes across exposure scenarios in 
order to evaluate whether a hazard occurs. A detailed discussion of the 
additional analyses and considerations that would inform EPA's process 
of making a hazard finding, or a finding of no hazard, are contained in 
the Approach. By itself, the Approach methodology cannot be used to 
determine whether hazards exist from P&CB renovations. EPA will need to 
conduct additional analyses and make certain science policy decisions 
in order to determine whether such hazards exist.
    EPA's Office of Pollution Prevention and Toxics (OPPT) has 
identified the Approach as an influential product and according to EPA 
peer review guidance is conducting an external peer review of that 
document, supplemental files, appendices (Ref. 4), and attendant models 
used for exposure scenarios. The external peer reviewers will assess 
the accuracy and content of the Approach, ensuring that the Approach 
and initial results are scientifically sound. The external peer review 
will also address the supplemental documents, which include detailed 
appendices for the Approach and a supplementary report relating lead 
exposure to Cardiovascular

Disease (CVD) mortality and proposing an approach to quantify adult 
health benefits from a reduction in lead (Pb) exposure for CVD 
mortality, entitled ``Developing a Concentration-Response Function for 
Pb Exposure and Cardiovascular Disease-Related Mortality'' (Ref. 5). 
The panel peer review meetings are expected to occur later in 2014, and 
the public will have an opportunity to review and comment on the 
materials given to the external peer reviewers.

III. Request for Comment

    EPA is requesting public review and comment on all aspects of the 
Approach and its supplemental files, appendices, attendant models, peer 
review charge (Ref. 6), and particularly related to the following:
     The utility of the Approach for estimating exposures 
through summarizing building use configuration types and human-activity 
patterns to incorporate variability across the wide variety of P&CBs.
     The utility of the updated Leggett Model (original model 
described in Leggett 1993 (Ref. 7); updated model described in the 
appendices to the Approach (Ref. 4)) to estimate blood lead levels for 
both children and adults, and specifically the use of the various 
outputs derived from the Leggett Model (concurrent blood lead, lifetime 
blood lead, and bone lead) in concentration-response curves for 
children and adults.
     The utility of concentration-response functions for health 
endpoints in both children and adults for assessing risk to human 
health inside P&CBs as a result of P&CB renovations.
