(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)

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.

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). 

1. In the Preamble, on p. 17686, in the 

third column, the seventh paragraph 

Estimated Total Burden Hours: 11.3 

million hours is revised to read 

Estimated Total Burden Hours: 

10,689,248 hours. 

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.

APPROXIMATE EQUIVALENCES AMONG CARCINOGEN CLASSIFICATION SCHEMES

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.

40 CFR Part 52 

[EPA–R03–OAR–2013–0013; FRL–9777–5] 

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.
