19556 Federal Register / Vol. 60, No. 75 / Wednesday, April 19, 1995 / Proposed Rules

40 CFR Part 63

[FRL–5193–1]

National Emission Standards for

Hazardous Air Pollutants (NESHAP);

Secondary Lead Smelters; PVC in

Feedstock

AGENCY: Environmental Protection

Agency (EPA)

ACTION: Proposed rule; amendments.

SUMMARY: Notice is given that the EPA

is considering amending the proposed

rule for secondary lead smelters (59 FR

29750, June 9, 1994). Information

gathered since proposal indicates that

the amount of polyvinyl chloride (PVC)

plastic contained in lead-acid battery

scrap is declining and should be

relegated to trace quantities within the

next few years. Polyvinyl chloride in

scrap is a precursor to hydrochloric acid

emissions. The EPA is considering

whether limits for hydrochloric acid

contained in the proposal should be

withdrawn.

DATES: Comments. Comments must be

received on or before May 4, 1995.

ADDRESSES: Comments. Comments

should be submitted (in duplicate, if

possible) to: Air and Radiation Docket

and Information Center (6102),

Attention Docket No. A–92–43, U.S.

Environmental Protection Agency, 401

M Street, SW., Washington, DC 20460.

The Agency requests that a separate

copy also be sent to the contact person

listed below.

Docket. Docket No. A–92–43 contains

supporting information used in

developing the proposed standards for

secondary lead smelters (59 FR 29750,

June 9, 1994). The docket is located at

the U.S. Environmental Protection

Agency, 401 M Street, SW., Washington,

DC 20460 in room M–1500, Waterside

Mall (ground floor), and may be

inspected from 8:30 a.m. to 12 p.m. and

1 to 3 p.m., Monday through Friday.

The proposed regulatory text and other

materials related to this rulemaking are

available for review in the docket or

copies may be mailed on request from

the Air Docket by calling (202) 260–

7548. A reasonable fee may be charged

for copying docket materials.

FOR FURTHER INFORMATION CONTACT: For

further information concerning the

proposed standards and the materials

discussed in this notice contact Mr. Phil

Mulrine at (919) 541–5289, Metals

Group, Emissions Standards Division

(MD–13), U.S. Environmental Protection

Agency, Research Triangle Park, North

Carolina 27711.

SUPPLEMENTARY INFORMATION: Since the

proposal of standards for secondary lead

smelters (59 FR 29750, June 9, 1994),

the EPA has continued to gather

information relevant to the rulemaking.

In the notice of proposed standards

for secondary lead smelters, the EPA

stated, ‘‘All smelting furnaces that

process broken batteries are potential

sources of HCl and Cl2 [chloride]

emissions. Many used lead-acid

batteries contain polyvinyl chloride

(PVC) plastic separators between the

battery grids, although the use of PVC

plastic as a separator material has been

discontinued by most battery

manufacturers. These separators are

typically not removed from the leadbearing parts of the battery during the

battery breaking and separation process.

When the PVC plastic is burned in the

smelting furnace, the chlorides are

released as HCl, Cl2, and chlorinated

hydrocarbons’’ (59 FR 29754).

Information gathered recently relevant

to this specific topic indicate that the

number of used lead-acid batteries in

the scrap inventory that contain PVC

plastic separators has declined sharply

in recent years from approximately 1

percent of the total available scrap in

1990 to less than 0.1 percent in 1994

(Docket No. A–92–43, Item No. IV–D–32

and IV–D–34). This trend is expected to

continue due to the fact that these

separators are no longer manufactured

in the United States (Docket No. A–92–

43, Item No. IV–D–38). No other source

of chlorides has been identified in the

feedstocks to these furnaces.

Consequently, the EPA also expects

emissions of HCl and Cl2 to follow a

similar decline.

In light of this new information, the

EPA is reconsidering the conclusion

that secondary lead smelters will

continue to be a source of HCl and Cl2

emissions and the need to regulate these

pollutants from this source category. At

this time, the EPA is considering

withdrawing the HCl/Cl2 emission

standards and associated monitoring

requirements from the proposed

NESHAP. The EPA welcomes comment

on this new information and the

ramifications it may have on the final

rule.

Assistant Administrator for Air and

Radiation.

BILLING CODE 6560–50–P

40 CFR Part 180

[OPP–300385; FRL–4947–9]

Potassium Oleate, Oxytetracycline,

and S-ethyl diisobutylthiocarbamate;

Proposed Tolerance Actions

AGENCY: Environmental Protection

Agency (EPA or ‘‘the Agency’’)

ACTION: Proposed rule.

SUMMARY: For each of the pesticides

subject to the actions listed in this

proposed rule, EPA has completed the

reregistration process and issued a

Reregistration Eligibility Document

(RED). In the reregistration process, all

information to support a pesticide’s

continued registration is reviewed for

adequacy and, when needed,

supplemented with new scientific

studies. Based on the RED tolerance

assessments for the pesticide chemicals

subject to this proposed rule, EPA is

proposing the following actions: to

delete the term potassium oleate from

the tolerance exemption for ‘‘potassium

oleate and related C12-C18 fatty acid

potassium salts,’’ to increase the

tolerance for oxytetracycline on

peaches, and for the tolerance ‘‘S-ethyl

diisobutylthiocarbamate,’’ to change the

chemical name to the common name

‘‘butylate’’, to delete certain terms, and

to change commodity definitions to

accord with Table II of Subdivision O.

DATES: Written comments, identified by

the OPP document control number

[300385], must be received on or before

May 19, 1995.
