II. Background A. What action is the agency taking? 
In the Federal Register of April 5, 
2019 (84 FR 13531) (FRL–9991–19), 
EPA promulgated a SNUR at 40 CFR 721.11193 for the chemical substance identified generically as alpha 1,3- polysaccharide (P–16–581). The SNUR designated certain activities as significant new uses. EPA has received new data on the biosolubility of the chemical substance. Based on its review of these data, EPA now proposes to revoke the SNUR pursuant to 40 CFR 721.185. In this unit, EPA provides a brief description of the chemical

substance, including the PMN number, 
generic chemical name, the Federal Register publication date and reference, 
the docket number, the basis for revoking the SNUR under 40 CFR 721.185, and the CFR citation of the SNUR. 
PMN Number: P–16–581 
Chemical name: Alpha 1,3- 
polysaccharide (generic). 
CAS number: Not available. 
Federal Register publication date 
and reference: April 5, 2019 (84 FR 
13531). 
Basis for revocation of SNUR: EPA 
issued a SNUR for this substance that designated certain activities as significant new uses based on a finding that the substance may pose potential human health hazards. Specifically, EPA identified a concern that adverse lung effects (i.e., lung overload) could 
occur if the chemical substance were manufactured, processed, or used in a manner that generated respirable particles. To address this hazard concern, EPA issued a SNUR under TSCA section 5(a)(2), which identified concerns for lung effects if the following protective measures were not followed: (1) No use of the substance other than the uses described in the PMN; and (2) no manufacture, processing, or use with particle size less than 10 micrometers. 
EPA also identified pulmonary effects toxicity testing as information potentially useful to characterize the health effects of the PMN substance. The PMN submitter performed biosolubility testing on the ground PMN substance and provided the test data to EPA on February 14, 2019. EPA initiated an internal review of these data; however, it moved forward with publishing the final SNUR on April 5, 2019 having not yet completed its review. The following are the results and conclusions of the Agency’s review. 
The biosolubility testing was 
conducted using a conservative respiratory tract fluid volume of 0.3 mL/ kg bw (rounded down to 20 mL for a 70 kg individual). This equated to a loading concentration of 15 mg of the PMN substance per mL of simulated epithelial lung fluid (SELF). The SELF represented the intraluminal volume of respiratory tract fluid, without consideration of the daily turnover volume. The estimated average alveolar fluid volume is approximately 37 mL, nearly double the volume used for the biosolubility testing. In comparison, the normal reference range for extra vascular lung water (EVLW) index in humans is 7.3 ± 2.8 mL/kg bw (n = 534) 
or 511 mL for a 70 kg individual. EVLW index corresponds to the ‘‘sum of interstitial, intracellular, alveolar, and lymphatic fluid, not including pleural effusions.’’ Therefore, the solubility of the PMN substance in SELF represented a worst-case loading concentration for the PMN substance in the intraluminal compartment, assuming an equivalent static volume of 20 mL. Given that humans accumulate respirable, poorly soluble particles in the intra-alveolar, interstitial, subpleural, and broncho- vascular bundle compartments, with a predominance of particles eventually being found in the interstitium, the extrapolated in vitro to in vivo 
concentration of the PMN substance would equal a loading concentration of approximately 3 mg/mL of EVLW (i.e., 1,500 mg/(511 mL for EVLW—37 mL for alveolar volume)) approximately 5 times lower than the loading concentration tested in the biosolubility study. 
This information supports EPA’s 
determination that the substance has inherently low toxicity and should not be considered a poorly soluble particle with the associated hazard concern for lung overload. Therefore, EPA proposes that the SNUR for this chemical substance be revoked pursuant to 40 CFR 721.185(a)(1). 
CFR citation: 40 CFR 721.11193 B. What is the agency’s authority for 
taking this action? 
Upon conclusion of the review for P– 
16–581, EPA designated certain activities as significant new uses. Under 40 CFR 721.185, EPA may at any time revoke a SNUR for a chemical substance which has been added to subpart E of 40 CFR part 721 if EPA makes one of the determinations set forth in 40 CFR 721.185(a)(1) through (a)(6). Revocation may occur on EPA’s initiative or in response to a written request. Under 40 CFR 721.185(b)(3), if EPA concludes that a SNUR should be revoked, the Agency will propose the changes in the Federal Register, briefly describe the grounds for the action, and provide interested parties an opportunity to comment. 
EPA has determined that the criteria 
set forth in 40 CFR 721.185(a)(1) have been satisfied for the chemical substance. Therefore, EPA is proposing to revoke the SNUR for this chemical substance. The significant new use notification and the recordkeeping requirements at 40 CFR 721.11193 would terminate when this proposed revocation becomes effective. In addition, export notification under TSCA section 12(b) and 40 CFR part 707, subpart D triggered by the SNUR would no longer be required. III. Statutory and Executive Order Reviews 
Additional information about these 
statutes and Executive Orders can be found at https://www.epa.gov/laws- regulations-and-executive-orders. 
This proposed rule would revoke or 
eliminate an existing regulatory requirement and does not contain any new or amended requirements. As such, the Agency has determined that this proposed SNUR revocation would not have any adverse impacts, economic or otherwise. 
A. Executive Order 12866: Regulatory 
Planning and Review and Executive Order 13563: Improving Regulations and Regulatory Review 
The Office of Management and Budget 
(OMB) has exempted these types of regulatory actions from review under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563, entitled (76 FR 3821, January 21, 2011). 
B. Paperwork Reduction Act (PRA) 
This proposed rule does not contain 
any information collections subject to 
approval under the PRA, (44 U.S.C. 3501 et seq.). 
C. Regulatory Flexibility Act (RFA) 
Pursuant to the RFA section 605(b), 5 
U.S.C. 601 et seq., the Agency hereby that this SNUR revocation would not have a significant economic impact on a substantial number of small entities. This proposed rule would eliminate a reporting requirement. 
D. Unfunded Mandates Reform Act 
(UMRA) 
For the same reasons, this action does 
not require any action under Title II of UMRA (2 U.S.C. 1531–1538 et seq.). 
E. Executive Order 13132: Federalism 
This proposed rule does not have 
Federalism implications, because it would not have substantial direct effects on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). 
F. Executive Order 13175: Consultation 
and Coordination With Indian Tribal Governments 
This proposed rule does not have 
Tribal implications, because it would not have substantial direct effects on one or more Indian Tribes, on the relationship between the Federal Government and Indian Tribes, or on the distribution of power and

responsibilities between the Federal 
Government and Indian Tribes, as specified in Executive Order (65 FR 67249, November 9, 2000). 
G. Executive Order 13045: Protection of 
Children From Environmental Health and Safety Risks 
This action is not subject to Executive 
Order 13045 (62 FR 19885, April 23, 1997), because this is not an economically significant regulatory action as defined under Executive Order 12866, and it does not address environmental health or safety risks disproportionately affecting children. 
H. Executive Order 13211: Actions 
Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use 
This proposed rule is not subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001), because this action is not expected to affect energy supply, distribution, or use and because this action is not a significant regulatory action under Executive Order 12866. 
I. National Technology Transfer and 
Advancement Act (NTTAA) 
In addition, since this action does not 
involve any technical standards, NTTAA section 12(d), 15 U.S.C. 272 note, does not apply to this action. 
J. Executive Order 12898: Federal 
Actions To Address Environmental Justice in Minority Populations and Low-Income Populations 
This action does not entail special 
considerations of environmental justice related issues as delineated by Executive Order 12898 (59 FR 7629, February 16, 1994).

SUPPLEMENTARY INFORMATION : 
I. Background 
DoD, GSA, and NASA are proposing 
to amend the FAR to implement section 855 of the John S. McCain National Defense Authorization Act (NDAA) for Fiscal Year (FY) 2019 (Pub. L. 115–232, 15 U.S.C. 644(w)). Section 855 requires Federal agencies to provide a notice, along with solicitations for construction contracts anticipated to be awarded to small businesses, to prospective offerors including information about the agency’s policies or practices in complying with FAR requirements related to the timely definitization of requests for equitable adjustment on construction contracts. The notice must include data regarding the time it took the agency to definitize requests for equitable adjustment on construction contracts for the three-year period preceding the issuance of the notice. 
II. Discussion and Analysis 
The proposed changes to the FAR are 
summarized in the following 
paragraphs. 
A. Solicitation notice regarding 
administration of change orders for construction. New text is proposed in 
FAR part 36, Construction and Architect-Engineer Contracts, subpart 36.5, Contract Clauses, to add coverage of the requirement for a new solicitation notice to be included in solicitations for construction. Specifically, new section 36.524, Notice to offerors regarding administration of change orders for construction, contains the prescription for the use of new solicitation provision 52.236–XX, Notice Regarding Administration of Change Orders for Construction. New section 36.524 also includes guidance for contracting officers regarding the information to be inserted in the provision. This new solicitation provision, which is proposed to be added in FAR part 52, Solicitation Provisions and Contract Clauses, will provide a standardized 
way for contracting officers to provide the notice required by section 855 of the NDAA for FY 2019.
