**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Boeing Model 747–100, 747–200B, 747–300, and 747SR series airplanes. That supplemental NPRM was published in the Federal Register on September 25, 2009 (74 FR 48882). That supplemental NPRM proposed to require installation of a closeout panel and moisture curtains for the main equipment center.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comment received from the sole commenter.
Request to Reference Revised Service Bulletin

Boeing requests that we revise the supplemental NPRM to refer to Revision 1, dated June 25, 2007, of Boeing Alert Service Bulletin 747–25A3346 for the shroud installation (paragraph (g) in the original NPRM). Boeing states that Revision 1 reroutes the forward drain tube installation, revises the pitot static lines, revises the moisture shroud inboard bracket installation, and revises the wire routing.

We disagree with Boeing’s request. As noted in the supplemental NPRM, we have removed the requirement to perform any actions in accordance with Boeing Alert Service Bulletin 747– 25A3346. We have not changed the AD in this regard.

Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting the AD as proposed.

Interim Action

We consider this AD interim action. The manufacturer is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking.


### 10670 Federal Register / Vol. 75, No. 45 / Tuesday, March 9, 2010 / Rules and Regulations

Explanation of Change to Costs of Compliance

Since issuance of the NPRM, we have increased the labor rate used in theCosts of Compliance from $80 per workhour to $85 per work-hour. The Costs of Compliance information, below, reflects this increase in the specified hourly labor rate. Costs of Compliance

We estimate that this AD affects 47 airplanes of U.S. registry. The following table provides the estimated costs, at an average labor rate of $85 per work hour, for U.S. operators to comply with this AD.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘ Subtitle VII: Aviation Programs, ’’ describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in ‘‘ Subtitle VII, Part A, Subpart III, Section 44701: General requirements. ’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings

This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the 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.

For the reasons discussed above, I certify that this AD:

(1) Is not a ‘‘ significant regulatory action ’’ under Executive Order 12866,

(2) Is not a ‘‘ significant rule ’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), and

(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment

**Drug Enforcement Administration**

**21 CFR Parts 1301, 1303, 1304, 1307, 1308, 1309, 1310, 1312, 1313, 1314,**  **1315, 1316, 1321**

**[Docket No. DEA–312F]**

**RIN 1117–AB19**

**Changes to and Consolidation of DEA Mailing Addresses** 

**AGENCY :**  Drug Enforcement Administration (DEA), Department of Justice.

**ACTION :**  Final rule.

**SUMMARY :**  DEA is amending Title 21 of the Code of Federal Regulations (CFR) to update and consolidate existing mailing addresses. Mailing addresses are being removed from the individual sections in which they currently appear and are being consolidated into one table in a new part 1321. DEA is making this change to the CFR to ensure registrants have the most current and accurate information, reduce administrative costs, and facilitate future address changes. A statement directing persons to the Table of DEA Mailing Addresses within the CFR is being provided in place of specific mailing addresses.

**DATES :**  Effective Date: This rule is effective March 9, 2010.

**SUPPLEMENTARY INFORMATION :**  DEA’s Legal Authority

DEA implements the Comprehensive Drug Abuse Prevention and Control Act of 1970, often referred to as the Controlled Substances Act (CSA) and Controlled Substances Import and Export Act (21 U.S.C. 801–971), as amended. DEA publishes the implementing regulations for these statutes in Title 21 of the Code of Federal Regulations (CFR), parts 1300 to end. These regulations are designed to ensure that there is a sufficient supply of controlled substances for legitimate medical purposes and to deter the diversion of controlled substances to illegal purposes.

Controlled substances are drugs and other substances that have a potential for abuse and psychological and physical dependence; these include substances classified as opioids, stimulants, depressants, hallucinogens, anabolic steroids, and drugs that are immediate precursors of these classes of substances. The CSA mandates that DEA establish a closed system of control for manufacturing, distributing, and dispensing controlled substances. Any person who manufactures, distributes, dispenses, imports, exports, or conducts research or chemical analysis with controlled substances must register with DEA (unless exempt) and comply with the applicable requirements for the activity.

The CSA, as amended, also requires DEA to regulate the manufacture, distribution, importation, and exportation of chemicals that may be used to manufacture controlled substances. Listed chemicals that are classified as List I chemicals are important to the manufacture of controlled substances. Those classified as List II chemicals may be used to manufacture controlled substances. Registrants are also required to provide other reports and information to DEA on an ongoing basis in compliance with a variety of statutory and regulatory obligations. Background

Currently, 21 CFR parts 1300 to end contain numerous office names and mailing addresses to which specific forms and other information are to be sent. However, oftentimes these mailing addresses and office names are not consistent and many are no longer accurate. DEA became aware of this internal inconsistency when it determined that, to improve agency management and efficiency, its Washington, DC, addresses would be moved to other locations. As DEA reviewed the number of addresses contained in 21 CFR, it became clear that a significant administrative burden would be involved in updating these addresses. DEA recognized that this administrative burden could potentially not be a one-time occurrence; that is, it is quite possible that DEA might move some of its mailing addresses in the future, necessitating further revisions to the CFR.

For registrants to have the most current mailing addresses to which applications, forms, and other materials are to be sent, DEA believes directing registrants and other interested persons to a single location within the CFR is the most practical way to convey current mailing address information. To address this, DEA is establishing a new part 1321 in the CFR that will contain the Table of DEA Mailing Addresses. Providing this information in the table format in the CFR allows for easy retrieval of necessary information in
