(c) Sulfur oxides shall be measured in

the ambient air as sulfur dioxide by the

reference method described in

Appendix A to this part or by an

equivalent method designated in

accordance with part 53 of this chapter.

(d) To demonstrate attainment, the

annual arithmetic mean and the secondhighest 24-hour averages must be based

upon hourly data that are at least 75

percent complete in each calendar

quarter. A 24-hour block average shall

be considered valid if at least 75 percent

of the hourly averages for the 24-hour

period are available. In the event that

only 18, 19, 20, 21, 22, or 23 hourly

averages are available, the 24-hour block

average shall be computed as the sum of

the available hourly averages using 18,

19, etc. as the divisor. If fewer than 18

hourly averages are available, but the

24-hour average would exceed the level

of the standard when zeros are

substituted for the missing values,

subject to the rounding rule of

paragraph (b) of this section, then this

shall be considered a valid 24-hour

average. In this case, the 24-hour block

average shall be computed as the sum of

the available hourly averages divided by

24.

3. Section 50.5 is revised to read as

follows:

§ 50.5 National secondary ambient air

quality standard for sulfur oxides (sulfur

dioxide).

(a) The level of the 3-hour standard is

0.5 parts per million (ppm), not to be

exceeded more than once per calendar

year. The 3-hour averages shall be

determined from successive

nonoverlapping 3-hour blocks starting at

midnight each calendar day and shall be

rounded to 1 decimal place (fractional

parts equal to or greater than 0.05 ppm

shall be rounded up).

(b) Sulfur oxides shall be measured in

the ambient air as sulfur dioxide by the

reference method described in appendix

A of this part or by an equivalent

method designated in accordance with

Part 53 of this chapter.

(c) To demonstrate attainment, the

second-highest 3-hour average must be

based upon hourly data that are at least

75 percent complete in each calendar

quarter. A 3-hour block average shall be

considered valid only if all three hourly

averages for the 3-hour period are

available. If only one or two hourly

averages are available, but the 3-hour

average would exceed the level of the

standard when zeros are substituted for

the missing values, subject to the

rounding rule of paragraph (a) of this

section, then this shall be considered a

valid 3-hour average. In all cases, the 3-

hour block average shall be computed as

the sum of the hourly averages divided

by 3.

Acid Rain Program: Continuous

Emission Monitoring

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Amendment to final rule;

correction.

SUMMARY: On May 17, 1995, EPA

published direct final amendments to

the Continuous Emission Monitoring

(CEM) rule in the Acid Rain Program for

the purpose of making implementation

of the program simpler, streamlined,

and more efficient. The amendments to

the original January 11, 1993 rule

became final and effective on July 17,

1995. During the public comment

period on the direct final rule and its

companion proposed rule, EPA received

significant, adverse comments on those

amended provisions that related to

notifications for periodic relative

accuracy test audits. EPA is removing

the provisions added in the direct final

rule related to notifications. EPA will

address the removed provisions in a

future final rule. EPA is also extending

the public comment period on the

removed provisions for 15 days to allow

the public to respond to the significant,

adverse comments. All other provisions

of the direct final rule remain final.

In addition, EPA is publishing

technical corrections of typographical

and similar inadvertent errors in the

final rule, as promulgated May 17, 1995.

DATES: Effective date: The effective date

of the amended rule provisions and

corrections is May 22, 1996.

Comment date: Comments in

response to the significant, adverse

comments on the direct final rule must

be received on or before June 6, 1996.

ADDRESSES: Any written comments in

response to the significant, adverse

comments on the direct final rule must

be identified as being in response to

such comments in Docket No. A–94–16

and must be submitted in duplicate to:

EPA Air Docket (6102), U.S.

Environmental Protection Agency, 401

M Street SW., Washington, D.C. 20460.

The docket is available for public

inspection and copying between 8:30

a.m. and 3:30 p.m., Monday through

Friday, at the above address. A

reasonable fee may be charged for

copying.

Agency, 401 M Street SW., Washington,

SUPPLEMENTARY INFORMATION: EPA

received significant, adverse comments

on certain provisions of the direct final

rule amending part 75 from a group of

utilities called the Texas Subgroup.

These comments were apparently

submitted on time, but EPA became

aware of this only after the provision

became final. After the close of the

comment period, the Texas Subgroup

submitted a letter, dated November 2,

1995, clarifying its comments. The

comments and the November 28, 1995

letter are found in Docket No. A–94–16,

items V–D–23 and V–D–24. The Texas

Subgroup made significant, adverse

comments on the provisions of

§§ 75.21(d)and 75.61(a)(5). Therefore,

those provisions in the direct final rule

are being removed and are considered

proposed provisions until EPA takes

further comment and addresses the

comments in a future final rule.

The Texas Subgroup commented

adversely upon the requirements in

§§ 75.21(d) and 75.51(a)(5) for

notifications of the date on which

periodic Relative Accuracy Test Audits

(RATAs) will be performed. The direct

final provisions require submission of

written notification to the

Administrator, the appropriate EPA

Regional Office, and the applicable State

or local air pollution control agency at

least 21 days before the scheduled date

of a RATA. The date may be

rescheduled if written or oral notice is

provided to EPA and to the appropriate

State or local air quality agency at least

seven days before the earlier of the

original scheduled date or the new test

date. The Texas Subgroup felt that this

provision created additional paperwork.

In addition, they felt the provisions

could force utilities to delay

rescheduled RATAs unnecessarily for

seven days simply to meet the

notification requirement.

In discussions with EPA, the Texas

Subgroup suggested that perhaps the

provisions are not needed or the

provisions could be revised to provide

more flexibility in the case where a

RATA is rescheduled. Some

possibilities that the Texas Subgroup

discussed with EPA included: allowing

utilities to receive permission from EPA,

State and local agency Acid Rain

Program contacts to proceed with

testing in less than seven days from the

date of notification; creating an

‘‘emergency’’ notification two days after

the new testing date is known, similar
Federal Register / Vol. 61, No. 100 / Wednesday, May 22, 1996 / Rules and Regulations 25581

to that for recertification

(§ 75.61(a)(1)(ii)); and allowing

notification electronically to reduce the

paperwork burden, where the EPA

Regional office or State or local agency

will accept such a notification.

EPA also notes that the purpose of the

notification for periodic RATAs is to

enable EPA or State or local agency staff

to observe the testing. Notifications of

periodic RATAs will allow EPA, State

and local agencies to observe a larger

percentage of units than if utilities only

were to submit notice for certification

and recertification testing. The ability of

agency staff to attend certification and

recertification testing is limited since

EPA has significantly shortened the

notification period for most

recertification tests and allows utilities

to proceed with recertification testing

before notifying the Agency in

emergency situations and since there

were a large number of sources testing

in a short time period during initial

certification. Even so, agency staff

attended many RATAs for initial

certification testing. However, initial

certification generally occurs before the

period when an affected unit is required

to comply with emission reductions.

Therefore, to enhance the quality of

quality assurance testing and the quality

of emission data during compliance,

EPA and State and local agencies need

the opportunity to observe periodic

RATAs. EPA notes that, during

certification testing, EPA personnel

have observed and corrected deviations

from acceptable stack testing

procedures. Based on these observations

during initial certification, EPA believes

it is critical for EPA, State, and local

agency personnel to be able to observe

periodic RATAs in order to ensure the

quality of monitored data for the Acid

Rain Program. Moreover, advance

notification of the date of periodic

RATA testing allows the cost-effective

use of agency resources by coordinating

auditing of monitor performance with

regularly scheduled quality assurance

testing and by coordinating field

observations at multiple locations. If

agency personnel were not to observe

periodic RATA testing, agencies would

need to perform or require performance

of additional RATAs under the audit

provisions of section 2.4 of Appendix B

of part 75. This would be more intrusive

for utilities, and more time-consuming

and costly for both utilities and

agencies, than coordinating with

periodic RATA testing.

The Agency notes that it is relatively

easy for a utility that schedules testing

to notify agencies of a known testing

date. In fact, it will take a utility roughly

the same amount of time to respond to

EPA and State or local agency enquiries

about testing dates as it takes the utility

to generate the short notice and mail it

or to make a telephone call. In contrast,

it is relatively difficult, time-consuming

and intrusive for State or local air

pollution control agencies or EPA

Regional Offices to contact each utility

with Phase I and II affected units to

determine when testing will occur at

each unit. EPA and State or local agency

personnel must call each utility, contact

the appropriate utility staff person, and

discuss the scheduling information.

In addition, EPA is considering

changes to the periodic RATA

notification provisions that would

reduce the burden of reporting a

notification. Part of the paperwork

burden could be eliminated by

removing the requirement that

notifications be provided to the

Administrator (received by EPA’s Acid

Rain Division). In addition, a State or

local air pollution control agency or

EPA regional office could be allowed to

waive the notification requirement. For

example, a State or local air pollution

control agency or an EPA regional office

could decide that it would not observe

a class of units (e.g., low-emitting gasfired units). EPA is therefore

considering allowing State or local air

pollution control agencies or EPA

Regional Offices to issue a utility a

waiver from periodic RATA notification

requirements for some or all utility units

within their respective States, air

quality districts or EPA regions until

notifications are specifically requested

again. This would relieve utilities of

some reporting burden, while still

ensuring that State or local agencies or

EPA regional offices would be able to

observe RATA testing when they

wished to do so. Moreover, where a test

needs to be rescheduled in less than

seven days, another option that would

create greater flexibility for utilities

would be a shorter period of advance

notification, such as telephone,

facsimile, or electronic mail notification

on the day the utility knows the

rescheduled date of testing, which

would be required to be at least two

days (48 hours) before the new date of

testing. EPA requests comment on these

possible solutions.

No other significant, adverse

comments were received by EPA on the

direct final rule. Thus, all other

provisions of the direct final rule

became final on July 17, 1995 and

remain in effect.

In addition, the EPA is correcting

various errors found in the direct final

rule, as promulgated on May 17, 1995.

These corrections are technical. Most

correct typographical errors; some

reinstate provisions that were

inadvertently removed from the final

regulations originally promulgated on

January 11, 1993 (58 FR 3590, 1993)

when the May 17, 1995 document was

published.

The rule provisions in this document

either remove requirements already

incorporated in the May 17, 1995 notice

or reinstate regulatory requirements that

were previously approved when the

regulations were originally issued on

January 11, 1993. The requirements of

Executive Orders 12866 and 12875, the

Regulatory Flexibility Act, the

Unfunded Mandates Act, and the

Paperwork Reduction Act are therefore

not applicable to this action. All

applicable administrative requirements

will be met when the proposed

amendments are addressed in a future

final rule.

direct final rule. 60 FR 26510 (May 17,

1995).

Protection of Stratospheric Ozone:

Listing of Substitutes for OzoneDepleting Substances

AGENCY: Environmental Protection

Agency.

ACTION: Final rule.

SUMMARY: This action finalizes

restrictions or prohibitions on

substitutes for ozone depleting

substances (ODSs) under the U.S.

Environmental Protection Agency (EPA)

Significant New Alternatives Policy

(SNAP) program. SNAP implements

section 612 of the amended Clean Air

Act of 1990 which requires EPA to

evaluate and regulate substitutes for the

ODSs to reduce overall risk to human

health and the environment. Through

these evaluations, SNAP generates lists

of acceptable and unacceptable

substitutes for each of the major

industrial use sectors. The intended

effect of the SNAP program is to

expedite movement away from ozone

depleting compounds while avoiding a

shift into high-risk substitutes posing

other environmental problems.

On March 18, 1994, EPA promulgated

a final rulemaking setting forth its plan

for administering the SNAP program (59

FR 13044), and issued decisions on the

acceptability and unacceptability of a

number substitutes. In this Final

Rulemaking (FRM), EPA is issuing its

preliminary decisions on the

acceptability of certain substitutes not

previously reviewed by the Agency. To

arrive at determinations on the

acceptability of substitutes, the Agency

completed a cross-media evaluation of

risks to human health and the

environment by sector end-use.

DATES: Effective date June 21, 1996.

The information collection

requirements contained in Appendix C

of subpart G of part 82 have not been

approved by the Office of Management

and Budget (OMB) and are not effective

until OMB has approved them. EPA will

publish a document in the Federal

Register announcing OMB approval.

ADDRESSES: Public Docket: Public

comments and data specific to this final

rule are in Docket A–91–42, Central

Docket Section, South Conference Room

4, U.S. Environmental Agency, 401 M

Street, SW., Washington, DC 20460. The

V. Additional Information

Appendix: Summary of Listing

Decisions

II. Section 612 Program

A. Statutory Requirements

Section 612 of the Clean Air Act

authorizes EPA to develop a program for

evaluating alternatives to ozonedepleting substances. EPA is referring to

this program as the Significant New

Alternatives Policy (SNAP) program.

The major provisions of section 612 are:

Rulemaking—Section 612(c) requires

EPA to promulgate rules making it

unlawful to replace any class I

(chlorofluorocarbon, halon, carbon

tetrachloride, methyl chloroform,

methyl bromide, and

hydrobromofluorocarbon) or class II

(hydrochlorofluorocarbon) substance

with any substitute that the

Administrator determines may present

adverse effects to human health or the

environment where the Administrator

has identified an alternative that (1)

reduces the overall risk to human health

and the environment, and (2) is

currently or potentially available.

Listing of Unacceptable/Acceptable

Substitutes—Section 612(c) also

requires EPA to publish a list of the

substitutes unacceptable for specific

uses. EPA must publish a corresponding

list of acceptable alternatives for

specific uses.

Petition Process—Section 612(d)

grants the right to any person to petition

EPA to add a substitute to or delete a

substitute from the lists published in

accordance with section 612(c). The
