Federal Register / Vol. 62, No. 174 / Tuesday, September 9, 1997 / Proposed Rules 47401

Alternative Tier 2 provisions for

baseline gasoline and oxygenated

gasolines, and the proposed schedule

for completion and submission of such

tests. A copy of the letter as well as the

proposed tests and schedule under the

Alternative Tier 2 provisions have been

placed in the Public Docket No. A–96–

16, Waterside Mall (Room M–1500),

Docket Section, 401 M Street, S.W.,

Washington, D.C. 20460. The

notification letter is also available on

the internet via the EPA’s Mobile

Sources home page at http://

www.epa.gov/OMSWWW/. The Agency

is requesting public comment on these

proposed requirements.

III. Environmental Impact

This proposal will result in no

immediate environmental impact, but

may provide a basis for further

regulatory action, should the collected

data indicate that health risks exist.

IV. Economic Impact

This proposed Alternative Tier 2

notification for baseline gasoline and

gasolines containing the specified

oxygenates will have a significant

impact on oil refiners and

manufacturers whose total annual sales

are more than $50 million. The F/FAs

regulations at 40 CFR 79.58(d) contain

provisions for those fuel or fuel additive

manufacturers whose total annual sales

are less than $50 million, and therefore

these parties are not subject to the

requirements in this notice.

SUPPLEMENTARY INFORMATION: On July

11, 1997 EPA published a Notice of Data

Availability (NODA) (62 FR 37183)

announcing the availability of its

mercury emissions study. The Mercury

Emissions study contains information

relating to the July 1994 proposed rule

addressing the management of spent

mercury-containing lamps. The Agency

established a 45-day comment period in

the NODA and indicated that comments

on the study would be accepted until

August 25, 1997. EPA has received

several written requests to extend the

comment period. The additional time

requested ranged from 45 to 90 days. As

justification for the time extension,

stakeholders noted the large amount of

information contained in the report and

the complexity of the study. The Agency

has decided to grant an additional 45

days beyond the initial 45-day comment

period to allow stakeholders additional

time to review the study and formulate

comments for the Agency’s

consideration. The Agency does not

believe that more than a 45-day

extension is necessary. Stakeholders

were aware of the types of issues that

would be discussed in the study and

have had, therefore, adequate time to

prepare comments to the Agency on the

general issues. As for specific

information presented in the study, 90

days provides adequate time to respond.

The Agency wishes to move forward

with the mercury-containing lamps

rulemaking and believes that an

extension beyond 45 days would cause

unnecessary delay. See 62 FR 37183

(July 11, 1997) for a more detailed

explanation of the study. Accordingly,

the Agency is extending the comment

period 45 days to October 9, 1997 to

provide for a 90-day comment period.

SUPPLEMENTARY INFORMATION: On April

19, 1996, EPA proposed revised

standards for hazardous waste

combustors (i.e., incinerators and

cement and lightweight aggregate kilns)

that burn hazardous waste. See 61 FR

17358. After an extension, the comment

period closed on August 19, 1996. In

that proposal, EPA included a

comparable fuels provision under which

EPA used a benchmark approach to

develop a series of technical

specifications that would allow

hazardous waste similar in composition

to a commercially available fossil fuel to

be excluded under RCRA when burned.

One of the specifications for comparable

fuels was a limit on total halogens in

comparable fuels. Although total

halogens are not listed in Appendix

VIII, Part 261, EPA proposed a total

halogen specification to ensure that

halogenated products of incomplete

combustion (PICs) and HCl and Cl2

generated from burning a comparable

fuel would not be emitted at higher

levels than from burning a benchmark

fossil fuel. See proposal (61 FR at

17461) and a subsequent notice of data

availability (61 FR 43501 (August 23,

1996)). PICs resulting from the burning

of halogenated compounds can pose a

particular hazard to human health and

the environment.

Using the benchmark approach, EPA

initially proposed total halogen 1

specifications ranging from 10 ppmw to

25 ppmw. These initial total halogen

specifications included both organic

and inorganic halogens. However, the

total halogen data used by EPA in the

proposed rule for its No. 4 and No. 6

fuel oils were based on analytical

methods measuring only total organic

halogens, not both organic and

inorganic halogens. EPA’s decision to

use a method that measured only

organic halogens for No. 4 and No. 6

fuel oils was based on two factors. First,

EPA was concerned about possible

method interferences and poor matrix

recovery when measuring total halogen

in No. 4 and No. 6 fuel oils and used

a method that measures only total

organic halogen.2 Second, EPA was

concerned that No. 4 and No. 6 fuel oils
