Revision to Oklahoma Regulation 1.5-

Reports Required; Excess Emissions

During Startup, Shutdown and

Malfunction of Equipment

AGENCY: Enviromental Protection

Agency.

ACTION: Final rulemaking.

SUMMARY: This action approves a

revision to the State of Oklahoma Air

Quality Control Implementation Plan

which was submitted by the Governor on February 8, 1983. Specifically, the

State revised Regulation 1.5-Reports

Required: Excess Emissions During

Startup, Shutdown and Malfunction of

Equipment to ensure the use of the

enforcement discretion approach by the

State and to meet EPA's criteria for a malfunction regulation. Prior to this

submittal, the State submitted a letter of

clarification to Regulation 1.5 on October 18, 1982, in response to a preliminary review by EPA. The State

submitted another letter of clarification on May 24, 1983. The proposed approval wa published on October 12, 1983, at 48

FR 46392. One comment was received

which supports EPA's action.

SUPPLEMENTARY INFORMATION: On

February 8,1983, the Governor of

Oklahoma submitted a SIP revision to

Regulation 1.5 (Reports Required: Excess

Emissions During Startup, Shutdown

and Malfunction of Equipment), as revised on June 1, 1981. EPA reviewed

the State's submittal and developed an evaluation report 1 in accordance with

the minimum criteria established by the

EPA policy memorandum dated,

September 28,1982 (Policy on Excess

Emissions During Startup, Shutdown,

Maintenance and Malfunctions) and the

clarification memorandum dated

February 15, 1983. This evaluation report

is available for inspection by interested

parties during normal business hours at

the EPA Region 6 office and the other

address listed above.

EPA believes that Oklahoma's

Regulation 1.5 is consistent with EPA's

malfunction policy. EPA's basic criterion

in reviewing malfunction regulations is

that the regulations must not provide for an automatic exemption during a maintenance/malfunction episode. The

State's response to automatic

exemptions as stated in their letter of

clarification dated, May 24,1983, is "the mere providing of the information

mandated in Sections 1.5(c)(2) (A), (B),

and (C) does not exempt the facility

from enforcement of the violation. The

violation can be pursued if the Chief

(i.e., The Department) is not satisfied

that excess emissions were not

unavoidable." This Is interpreted as the

Chief exercising his enforcement

discretion depending on the

circumstances surrounding the excess emissions rather than an automatic

exemption. The State will use the

information submitted in response to the

requirements of Regulation 1.5 to

I EPA Evaluation Report for Oklahoma

Regulation 1.5-Reports Required: Excess Emissions

During Startup, Shutdown and Malfunction of

Equipment.

determine whether enforcement action

is appropriate.

The policy memoranda list 5 other

criteria which a State's malfunction

regulation must meet and they are:

(1) To the maximum extent practicable, the

air pollution control equipment, process equipment, or processes were at all times

maintained and operated, In a manner

consistent with good practice for minimizing emissions;

Regulation 1.5-This criterion is met under

Section 1.5(e)(2)(H), along with the October

18,1982, clarification letter. The State stated

that "it is the intent that Section 1.5(e((1-] allows the Chief of the Air Quality Service to

require the submission of preventive maintenance plans necessary to prevent, detect and correct malfunctions of

equipment." EPA interprets this to include

documentation on process equipment or

processes. (2) Repairs were made in an expeditious fashion when the operator knew or should'

have known that applicable emission

limitations were being exceeded, Off shift

and overtime labor must have been utilized

to insure that such repairs were made as

expeditiously as possible; Regulation 1.5-This criterion Is met under

Section 1. (c)(2)(B), along with the October

18, 1982, clarification letter. The State

ndicated that "sources are also required to

demonstrate to the satisfaction of the Chief of

the Air Quality Service in a timely manner that measures such as off-shift and overtime

labor have been used to effect repairs and

minimize emissions."

(3) The amount and duration of the excess emissions (including any bypass) were minimized to the maximum extent practicable during periods of such emissions;

Regulation 1.5--This criterion is met under

Sections 1.5(e)(2) (B), (C), and (G).

(4) All possible steps were taken to

minimize the impact of the excess emissions on ambient air quality; and

Regulation 1.5-This criterion Is met under

Sections 1.5(c)(2(B) and 1.5(e)(2) (F) and (C),

(5) The excess emissions are not part of a recurring pattern indicative of inadequate

design, operation or maintenance.

Regulation 1.5--This criterion is met under

Sections 1.5(c](2)(C] and 1.5(O(2](C).

I The State was asked to clarify excess

emissions during scheduled

maintenance under Section 1.5(c)

Notification Requirements. Their May

24, 1983, clarification letter states that

"It is the intent of this regulation to

allow the Chief not to pursue

enforcement of violations due to

removing control equipment from

operation to perform maintenance * *

The regulation requires that pollution

control equipment maintenance be

accomplished to the extent possible

when the process is shut down," As the

regulation is written and interpreted by

the State, excess emissions during.

sch'duled maintenance are not excused,

However, in using the enforcement

HeinOnline -- 49 Fed. Reg. 3084 1984
Federal Register / Vol. 49, No. 17 / Wednesday, January 25, 184 / Rules and Regulations

discretion approach, the State may

conclude from an examination of the

facts surrounding the event that no

enforcement action is appropriate. If

EPA takes a different view of the facts

and believes that enforcement action is

necessary because of the 6xcess

emissions, EPA still has the legal

authority to take that action.

.The State was also asked to clarify

Section 1.5[f) Excesses Resulting From

Engineering Limitations. Their May 24,

1983, clarification letter states "This

section does not grant automatic

exemptions. This section is designed to

reduce the administrative burden on

process startup/shutdowns. There are

some processes that invariably will emit

excess emissions during this phase of

their operation... The approach

requires prior approval, but upon

approval allows the source to report

these occasions on a quarterly basis.

Thus, the State can review quarterly the

occurrences to assure that excessive

startup/shutdowns are not occurring. If

excessive startup/shutdowns are

occurring, the State will take

appropriate action." EPA accepts this

interpretation.

In the October 12,1983, Federal

Register Notice, EPA solicited public

comment Only one comment was

received and it was in support of the

proposed approval.

Regulation 1.5 along with the

clarification letter dated, October 18,

1982, and May 24,1983, meets all of

EPA's minimum criteria for an

approvable malfunction regulation.

Based on this, EPA is hereby approving

Regulation 1.5.

The Office of Management and Budget

has exempted this rule from the

requirements of Section 3 of Executive

Order 12291.

Under Section 307(b)(1) of the Act,

petitions for judicial review of this

action must be filed in the United States

Court of Appeals for the appropriate

circuit by (60 days from today). This

action may not be challenged later in

proceedings to enforce its requirements.

SUMMARY: As required by section

25(a)(4) of the Federal Insecticide,

Fungicide, and Rodenticide Act (FIFRA),

EPA submitted a final regulation

establishing procedures for the

conditional registration of pesticide

products -which are Identical or

substantially similar to those currently

registered, and the conditional

registration of new uses of existing

pesticides by EPA to both Houses of

Congress for review prior to the

regulation taking effect. The regulation

was published in the Federal Register of

July 26,1983 (48 FR 34000). The minimum

60-day period for Congressional review

ended on November 10,1983.

OATm The regulation became effective

on November 10,1983.

SUPPLEMENTARY INFORMATION EPA

issued a final regulation, which was

published In the Federal Register of July

20,1983 (48 FR 34000), under section 3 of

FIFRA. The regulation established

procedures for the conditional

registration of pesticide products which

are Identical or substantially similar to

those currently registered, and the

conditional registration of new uses of

existing pesticides, by the Agency. The

rule also replaced current regulations on

conditional registration that the Third

Circuit Court of Appeals found had been

issued without adequate notice and

comment. However, as required by

section 23(a)(4) of FIFRA, the regulation

could not tahe effect until it had been

submitted to both Houses of Congress

for a period of 60 days of continuous

Congressional session, as defined by

section 25(a)(4). Since it was not

possible to predict an exact date on

which the Congressional review period

would end, the preamble to the final

regulation stated that EPA would issue a

separate Federal Register notice after

the review period was over announcing

the effective date of the regulation. On

November 10,1933, 60 days of

continuous Congressional session

elapsed.

Accordingly, the final regulation

promulgated on July 26,1933 (48 FR

34000). became effective on November

10,1983.
