(b) Unsafe Condition

This AD defines the unsafe condition as a decrease, over time, in the strength of a T– T strap caused by moisture. This condition could result in failure of a T–T strap, loss of directional control, and subsequent loss of control of the helicopter.
(c) Effective Date

This AD becomes effective March 15, 2013. (d) Compliance

You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time. (e) Required Actions

(1) Within six months, determine the manufacturer’s cure date of each of the 13 T– T straps.

(i) For a T–T strap with five or more calendar years from the manufacturer’s cure date, before further flight, replace the T–T strap with an airworthy T–T strap.

(ii) For a T–T strap with less than five calendar years from the manufacturer’s cure date, mark the expiration date on the T–T strap face in permanent ink.

(2) Thereafter, before installing a T–T strap, mark the expiration date on the T–T strap using permanent ink. The expiration date is five years from the date the T–T strap package was opened, or if that date was not recorded, five years from the manufacturer’s cure date.

(3) On or before the date you comply with paragraph (e)(1) or (e)(2) of this AD, create a component record card for each T–T strap and record on the card the manufacturer’s cure date or the date that the T–T strap package was opened, if that date was recorded previously, and the T–T strap expiration date.

(4) Revise the Airworthiness Limitations section of the maintenance manual by establishing:

(i) A calendar life limit for the T–T straps, P/N 500N5311–5, 900R3442009–101, 900R3442009–103, and 900R6442009–103 of five years from the date the T–T strap package was opened, or if that date was not recorded, five years from the manufacturer’s cure date.

(ii) A 2,500 hour time-in-service (TIS) life limit for any T–T straps, P/N 500N5311–5, installed on a Model 500N or Model 600N helicopter that was previously installed on a Model MD900 helicopter.

Note to paragraph (e) of this AD: For the MDHI Model MD900 helicopters, AD 2006– 18–01 (71 FR 51095, August 29, 2006) contains additional TIS life limits for T–T straps, P/N 900R3442009–103 and P/N 900R6442009–103 and additional inspection requirements for all four affected T–T straps, P/N 500N5311–5, P/N 900R3442009–101, P/ N 900R3442009–103, and P/N 900R6442009–
103. (f) Alternative Methods of Compliance (AMOCs)

**SUPPLEMENTARY INFORMATION** 

### : I. Background

This notice corrects certain minor errors in the revisions to OSHA’s Hazard Communication Standard, published at 77 FR 17574. The majority of these corrections change references in other OSHA standards made to ‘‘material safety data sheet’’ or ‘‘MSDS’’ to ‘‘safety data sheet’’ or ‘‘SDS,’’ which OSHA inadvertently missed in its original publication of the final rule. Other corrections include correcting values or notations in tables, and updating references to terms defined in the Hazard Communication Standard Final Rule, published on March 26, 2012. Correction of Publication

The following corrections are made to the preamble to the final rule for the Hazard Communication Standard, published in the Federal Register on March 26, 2012 (77 FR 17574).

2. In the Preamble, on p. 17755, in the third column, in the first paragraph the name ‘‘David Levine’’ is corrected to read ‘‘Daniel Levine’’.

3. In the Preamble, on p. 17712, Table XIII–1, the ‘‘>20%’’ value for Specific target organ toxicity Category 3 is corrected to read ‘‘ ≥ 20%’’ (both columns).

4. In the Preamble, on p. 17751, Table XIII–5, Health Effects Column for Standard No. 1910.1051. ‘‘Cancer; eye and respiratory tract irritation; center nervous system effects; and flammability’’ is corrected to read

### II. Exemption From Notice-andComment Procedures

Section 4 of the Administrative Procedure Act, 5 U.S.C. 553(b)(3)(B), provides that, when an Agency for good cause finds that notice and public procedure are impracticable, unnecessary or contrary to the public interest, the Agency may issue a final rule without providing notice and an opportunity for public comment. This rulemaking only corrects errors of a minor, mainly typographical nature and therefore does not affect or change any existing rights or obligations. OSHA has determined that there is good cause, pursuant to 5 U.S.C. 553(b)(3)(B), Section 6(b) of the Occupational Safety and Health Act of 1970 (29 U.S.C. 655(b)), and 29 CFR 1911.5, for making this correctional amendment final without prior proposal and opportunity for comment because the rulemaking does not affect or change any existing rights or obligations, and no stakeholder is likely to object to them. For the same reasons, the Agency finds good cause under 5 U.S.C. 553(d)(3) to make the amendment effective upon publication. III. Authority and Signature

David Michaels, Ph.D., MPH, Assistant Secretary for Occupational Safety and Health, U.S. Department of Labor, 200 Constitution Avenue NW., Washington, DC 20210, authorized the preparation of this document.

IARC GHS NTP RoC

Group 1 ........................................... Category 1A ................................... Known. Group 2A ......................................... Category 1B ................................... Reasonably Anticipated (See Note 1). Group 2B ......................................... Category 2 ..................................... Reasonably Anticipated (See Note 1).

Note 1:
1. Limited evidence of carcinogenicity from studies in humans (corresponding to IARC 2A/GHS 1B);

2. Sufficient evidence of carcinogenicity from studies in experimental animals (again, essentially corresponding to IARC 2A/GHS 1B);

3. Less than sufficient evidence of carcinogenicity in humans or laboratory animals; however:

a. The agent, substance, or mixture belongs to a well-defined, structurally-related class of substances whose members are listed in a previous RoC as either ‘‘Known’’ or ‘‘Reasonably Anticipated’’ to be a human carcinogen, or

b. There is convincing relevant information that the agent acts through mechanisms indicating it would likely cause cancer in humans.

### Approval and Promulgation of Air **Quality Implementation Plans; Maryland; Removal of the Mount Saint**  **Mary’s College 1979 Consent Order**

**AGENCY** 

### : Environmental Protection Agency (EPA).

**ACTION** 

### : Direct final rule.

**SUMMARY** 

### : EPA is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the Maryland Department of the Environment (MDE) pertaining to the F. Keeler Company Boiler at Mount Saint Mary’s College. This revision removes the Mount Saint Mary’s College 1979 Consent Order (1979 Consent Order) from the Maryland SIP because the coal-fired F. Keeler Boiler has been modified by removing the coal-firing capability and converting the boiler to fire natural gas with No. 2 fuel oil as backup. EPA is approving this SIP revision because the 1979 Consent Order is no longer required as the modified gas-fired unit can comply with all visible emission and particulate requirements in the Maryland SIP, and this 1979 Consent Order is no longer required to satisfy any applicable Federal regulations or the Clean Air Act (CAA). This action is being taken under the CAA.
