concentrations (mg/kg) for these six data

sets are as follows: untreated 5.17,

treated 10.2; untreated 17.9, treated

11.0; untreated 7.89, treated 10.1;

untreated 3.40, treated 8.90; untreated

4.82; treated 10.3; and untreated 8.14,

treated 9.61. No quality assurance/

quality control documentation is

provided with this data. The source(s) of

the potliner is not identified.

b. Ormet Delisting Petition

Data from the Ormet Primary

Aluminum Corporation facility in

Hannibal, Ohio was submitted to EPA in

April 1994. The report, titled Petition

for Exclusion for Vitrified Product From

Spent Potliner, requested a delisting of

their residues from their vitrification

treatment process. The data in the report

include arsenic concentrations found in

five samples, taken from a pilot-scale

combustion melting system (CMS)

vitrification process to treat K088

wastes. Total arsenic concentrations

(mg/kg) in the five treated waste

samples are reported as: <2, <5, <5, <5,

and 4.2. Quality assurance/quality

control documentation for this data set

consists of duplicate samples and

matrix spike recoveries reported for

three of the five samples.

c. Correspondence From Vortec

Corporation

Pursuant to a request by the Agency

for ‘‘totals’’ data from residuals

produced from the vitrification of K088

in Vortec Corporation’s vitrification

process, data was received by the

Agency in a letter from R. Sarah

Compton, Kilpatrick Stockton LLP to

Ms. Marilyn Goode, U.S. Environmental

Protection Agency, dated February 26,

1997. In this letter, total arsenic

concentrations are reported from two

pilot-scale treatability studies

conducted on K088 waste. The first data

set concerned tests conducted on waste

generated by Ravenswood Aluminum.

This data consists of only one datum

point for total arsenic, which was

measured as ‘‘not detected’’ (less than 3

mg/kg total arsenic). The second data set

shows the results of a pilot-scale

treatability study of K088 wastes

generated by Alumax Corporation. Total

arsenic concentrations (mg/kg) for this

data set consist of seven data points: 4,

5, <3, <3, <3, <3, and <3. No quality

assurance/quality control (QA/QC)

documentation is provided for either of

the data sets.

III. Development of Total Arsenic

Treatment Standard

As noted, the Agency is noticing for

comment five data sets, one or more of

which will likely be used to develop a

total arsenic treatment standard for

K088 waste that will be promulgated by

September 24, 1998. The Agency’s Land

Disposal Restrictions Program (LDR) has

specific requirements for any data set

evaluated for possible Best

Demonstrated Available Technology

(BDAT) analysis. A full range of

information is necessary to determine

whether a treatment and its

corresponding performance data

warrants further evaluation for possible

development of the treatment standard.

For example, waste characterization;

treatment design and operating

conditions; and quality assurance/

quality control (QA/QC) documentation

are all necessary components of a

‘‘BDAT quality’’ data set. See USEPA

‘‘Final Best Demonstrated Available

Technology (BDAT) Background

Document for Quality Assurance/

Quality Control Procedures and

Methodology,’’ Office of Solid Waste,

October 23, 1991.

The Agency is currently conducting a

thorough evaluation of the

aforementioned data sets with regard to

the BDAT protocols. If, however, the

Agency were to calculate a treatment

standard from one of these data sets as

they are presented today, a total arsenic

treatment standard for K088 would

range between 5 and 26 mg/kg total

arsenic, depending on the data set.

ACTION: Extension of comment period.

SUMMARY: This notice grants a request to

publication of the proposal, the agency

received a request for extension of the

comment period for 60 days in order to

prepare a consolidated comment to

submit in response thereto. Thus,

NHTSA is extending the comment

period from August 4, 1998 to October

5, 1998.

SUPPLEMENTARY INFORMATION: On June 5,

1998 NHTSA published a NPRM

proposing to amend 49 CFR 575.104 by

changing the treadwear grading

procedures in UTQGS. Briefly stated,

the agency proposed to use a direct

comparison of the wear rates of course

monitoring tires (CMT) used as the

control standard with the candidate

tires, that is, the tires being tested for

the purpose of grading. Further, NHTSA

proposed to measure the wear rates of

CMTs 4 times per year and use the

average wear rate from the last 4

quarterly CMT tests as a basis for the

base course wear rate (BCWR) from

which tire grades are determined. The

agency further proposed that CMTs used

to determine wear rate would be no

more than 6 months old at the

commencement of the test and that the

difference in production dates of those

tires would be no greater than 3 months.

The NPRM specified a comment

closing date of August 4, 1998 (60 days

after date of publication). However, the

agency received a request for an

extension of the comment closing date

from the Rubber Manufacturers

Association (RMA). The RMA stated

that it is reviewing the NPRM and

supporting data that are in a document

entitled Critical Evaluation of UTQG

Treadwear Testing & Methodology.

Because of the quantity and complexity

of the data, RMA stated that it will not

be able to complete its review and

prepare consolidated comments of its

members prior to the closing date of

August 4, 1998. Therefore, RMA

requested an additional 60 days for

submission of its comments.

Since the RMA is the primary

national trade association for the

finished rubber products industry in the

United States, the agency is interested

in its comments. Thus, in order to

provide the RMA and other interested

parties ample time and opportunity to

express their views on the UTQGS

proposals, NHTSA believes that there is

good cause for the extension of the

comment period and that such

extension is consistent with the public

interest. Accordingly, the RMA request

to extend the comment period for an

additional 60 days is granted.

The agency notes that the 60th day

falls on a Saturday. Therefore, in order

to close the comment period on a

business day, the extended comment

closing date will now be October 5,

1998.

Authority: 49 U.S.C. §§ 322, 30111, 30115,

30117, and 30166; delegation of authority is

at 49 CR 1.50.

Issued on: July 28, 1998.
