Docket No. 06–AWP–15] 

RIN 2120–AA66 

Proposed Establishment of Class D 

Airspace; Castle Airport, Atwater, CA 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking. 

SUMMARY: This notice proposes to 

establish Class D airspace at Castle 

Airport, Atwater, CA. A contract Airport 

Traffic Control Tower (ATCT) is being 

established at Castle Airport, Atwater, 

CA, which will meet criteria for Class D 

airspace. Class D airspace is required 

when the ATCT is open, and to contain 

and protect Standard Instrument 

Approach Procedures (SIAPs) and other 

Instrument Flight Rules (IFR) operations 

at the airport. This action would 

establish Class D airspace extending 

upward from the surface to 2,500 feet 

Mean Sea Level (MSL) within a 4.5 

nautical mile radius of the airport. 

DATES: Comments must be received on 

or before December 13, 2006. 

ADDRESSES: Send comments on this 

proposal to the Docket Management 

System, U.S. Department of 

Transportation, Room Plaza 401, 400

The Proposal 

The FAA is considering an 

amendment to part 71 of the Federal 

Aviation Regulations (14 CFR part 71) to 

establish Class D airspace at Castle 

Airport, Atwater, CA. An ATCT is being 

contracted at Castle Airport, and Class 

D airspace is required during the hours 

the ATCT is open. Class D controlled 

airspace is necessary for the safety of 

aircraft executing SIAPs and other IFR 

operations at Castle Airport. Class D 

airspace will be effective during 

specified dates and times established in 

advance by a Notice to Airmen. The 

effective date and time will, thereafter, 

be published in the Airport/Facility 

Directory. 

Class D airspace designations for 

airspace areas extending upward from 

the surface of the earth are published in 

Paragraph 5000 of FAA Order 7400.9P, 

dated September 1, 2006, and effective 

September 15, 2006, which is 

incorporated by reference in 14 CFR 

71.1. The Class D airspace designations 

listed in this document would be 

published subsequently in the Order. 

The FAA has determined that this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. It, 

therefore, (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) does not warrant 

preparation of a Regulatory Evaluation 

as the anticipated impact is so minimal. 

Since this is a routine matter that will 

only affect air traffic procedures and air 

navigation, it is certified that this rule, 

when promulgated, will not have a 

significant economic impact on a 

substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

CONSUMER PRODUCT SAFETY 

COMMISSION 

16 CFR Parts 1630 and 1631 

Technical Amendment to the 

Flammability Standards for Carpets 

and Rugs 

AGENCY: Consumer Product Safety 

Commission. 

ACTION: Proposed amendments. 

SUMMARY: The Commission proposes to 

amend the flammability standards for 

carpets and rugs to remove the reference 

to Eli Lilly Company Product No. 1588 

in Catalog No. 79, December 1, 1969, as 

the standard ignition source and 

provide a technical specification 

defining the ignition source.1 The 

proposed specification for the standard 

ignition source is a timed burning tablet, 

consisting of essentially pure 

methenamine, with a nominal heat of 

combustion value of 7180 calories/gram, 

a mass of 150 mg +/¥5 mg, flat, and a 

nominal diameter of 6 mm. An 

immediate effective date is also 

recommended. 

DATES: Written comments concerning 

the proposed amendments must be 

received by the Office of the Secretary 

not later than January, 29, 2007. 

ADDRESSES: Comments may be filed by 

e-mail to cpsc-os@cpsc.gov, and should 

be captioned ‘‘CARPET AND RUG 

TECHNICAL AMENDMENT.’’

Comments may also be mailed, 

preferably in five copies, to the Office of 

the Secretary, Consumer Product Safety 

Commission, Room 502, 4330 East-West 

Highway, Bethesda, Maryland 20814, or 

delivered to the same address 

(telephone (301) 504–0800). Comments 

may also be filed by facsimile to (301)

SUPPLEMENTARY INFORMATION: 

A. Background 

The standards for surface 

flammability of carpets and rugs appear 

at 16 CFR Parts 1630 and 1631. They 

were codified and published in 1975, 40 

FR 59931 and 59935 (December 30, 

1975). The standards were originally 

issued in 1970 by the Department of 

Commerce under the authority of the 

Flammable Fabrics Act (FFA). Subpart 

A of 16 CFR Parts 1630 and 1631 sets 

forth the standards. Subpart B contains 

the implementing regulations of the 

standards. Subpart C contains 

alternative washing procedures for hide 

carpets and rugs and wool flokati 

carpets and rugs. Subpart D of 16 CFR 

1630 contains the staff interpretations 

and policies. 

16 CFR Parts 1630 and 1631 establish 

minimum acceptance criteria for the 

surface flammability of carpets and rugs 

when exposed to a standard small 

source of ignition, a burning 

methenamine tablet, under prescribed 

conditions (the ‘‘pill test’’). These 

standards reduce the risks of death, 

personal injury, and property damage 

associated with fires that result from the 

surface ignition of carpets and rugs. 

Both standards require a timed 

burning tablet as the standard ignition 

source for flammability performance 

testing. The standards define the 

ignition source at 16 CFR Part 1630.1(f) 

and 1631.1(f) as a methenamine tablet, 

weighing approximately 0.149 grams 

(2.30 grains), sold as Product No. 1588 

in Catalog No. 79, December 1, 1969 by 

the Eli Lilly Company, or an equal 

tablet. 

In April 2002, Commission staff 

learned that the Eli Lilly Company was 

no longer producing the methenamine 

tablets specified in the carpet and rug 

standards. Although the standards allow 

for the use of ‘‘an equal’’ methenamine 

tablet and give parameters for chemical 

composition and weight of the tablet, 

they do not provide any guidance on 

determining whether tablets from 

alternative sources are ‘‘equal’’ to those 

manufactured by the Eli Lilly Company. 

In July 2003, CPSC staff met with 

representatives of the Carpet and Rug 

Institute (CRI) to discuss evaluation of 

alternative methenamine tablets for use 

in 16 CFR Part 1630 and Part 1631. CRI 

members were experiencing differing 

test results using the old Eli Lilly tablets 

and currently available tablets. CRI 

members had begun to study the various 

characteristics of the current tablets. In 

one case, about 50% of one 

manufacturer’s tablets were found 

broken in the bottle, with others 

breaking later. This problem was 

attributed to the tablets having a domed 

top. The problem has since been 

corrected with a flat tablet. 

CRI urged the Commission to specify 

clearly the characteristics of the ‘‘equal’’

tablets that should be used for 

determining compliance with the carpet 

and rug standards. In an effort to make 

such a determination, the Commission 

staff conducted a comparison study to 

evaluate the weight, chemical 

composition, and combustion 

characteristics of presently available 

brands of methenamine tablets relative 

to each other and those produced by the 

Eli Lilly Company. The outcome of the 

study indicated that tablets consisting of 

essentially pure methenamine, having a 

heat of combustion value of 

approximately 7180 calories/gram and 

weighing approximately 0.149 grams 

may be considered equivalent to the 

tablets produced by the Eli Lilly 

Company and referenced in the 

regulation. 

On July 29, 2004, the Commission’s 

Office of Compliance issued a letter to 

industry in response to inquiries 

received by the CPSC staff regarding the 

equivalency of methenamine tablets 

formerly manufactured by the Eli Lilly 

Company and similar tablets currently 

produced by other manufacturers. The 

letter stated that the Commission staff 

determined that tablets consisting of 

essentially pure methenamine and 

weighing approximately 0.149 grams 

may be considered equivalent to the 

tablets formerly produced by the Eli 

Lilly Company. Therefore, tablets 

meeting these criteria may be used for
