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 ofOklahoma 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 ofthe enforcement discretion approach by the State and tomeet 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 ofclarification

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. EFFECTIVE DATE: Effective on February 24, 1984. ADDRESSES: Incorporation byreference material is available for inspection during normal business hours at the following locations:

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 ofEquipment), as revised on June 1, 1981. EPAreviewed 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 andMalfunctions) 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 inreviewing 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 ofthe information mandated in Sections 1.5(c)(2) (A), (B), and (C) does not exempt the facility from enforcement ofthe violation. The violation can be pursued ifthe Chief (i.e., The Department) is not satisfied that excess emissions were not unavoidable." This Is interpreted as the Chiefexercising his enforcement discretion depending on the circumstances surrounding the excess emissions rather than anautomatic exemption. The State will use the information submitted in response to the requirements ofRegulation 1.5 to

I EPA Evaluation Report forOklahoma Regulation 1.5-Reports Required: Excess Emissions During Startup, Shutdown andMalfunction 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 themaximum extent practicable, the air pollution control equipment, process equipment, orprocesses were at all times maintained and operated, Ina manner consistent with good practice for minimizing emissions;

Regulation 1.5-This criterion ismet under Section 1.5(e)(2)(H), along with the October 18,1982, clarification letter.The State stated that "itis the intentthat Section 1.5(e((1-] allows the Chiefofthe Air Quality Service to require the submission ofpreventive maintenance plansnecessary to prevent, detect and correct malfunctions of equipment." EPAinterprets this toinclude documentation onprocess equipment or processes.

(2) Repairs were made in an expeditious fashion when the operatorknew or should' have known that applicable emission limitations were being exceeded, Offshift and overtime labor must have been utilized to insure that such repairs were made as expeditiously aspossible;

Regulation 1.5-This criterion Ismet 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 Chiefof the Air Quality Service in a timely manner thatmeasures such as off-shift and overtime labor have been used to effect repairs and minimize emissions."

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

on ambient airquality; and

Regulation 1.5-This criterion Ismet under Sections 1.5(c)(2(B) and 1.5(e)(2) (F) and (C),

(5)

The excess emissions are notpart of a recurring pattern indicative ofinadequate 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 Chiefnot to pursue enforcement ofviolations 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

### Federal Register 

### / Vol. 49, No. 17 / Wednesday, January 25, 184 / Rules and Regulations

discretion approach, the State may conclude from anexamination ofthe facts surrounding the event that no enforcement action is appropriate. If EPA takes a different view ofthe facts andbelieves that enforcement action is
necessary because ofthe 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. TheirMay 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 thatinvariably will emit

excess emissions during this phase of their operation... The approach requires prior approval, but upon approval allows the source toreport these occasions on a quarterly basis. Thus, the State canreview quarterly the

occurrences to assure thatexcessive 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 ofManagement and Budget has exempted this rule from the requirements ofSection 3 ofExecutive Order 12291.

Under Section 307(b)(1) ofthe Act, petitions forjudicial review ofthis action must be filed in the United States Court ofAppeals for the appropriate circuit by (60days from today). This action may not be challenged later in proceedings to enforce its requirements. (See 307(b)[2).)

Incorporation by reference ofthe State Implementation Plan for the State ofOklahoma was approved by the Director ofthe Federal Register onJuly 1, 1982.

SUPPLEMENTARY INFORMATION EPA 

### issued a final regulation, which was published In the Federal Register ofJuly 20,1983 (48 FR 34000), under section 3of FIFRA. The regulation established procedures for the conditional registration ofpesticide products which

are Identical or substantially similarto those currently registered, and the conditional registration ofnew uses of existing pesticides, bytheAgency. The rule also replaced current regulations on conditional registration that theThird Circuit Court ofAppeals found hadbeen issued without adequate notice and
comment. However, asrequired by section 23(a)(4) ofFIFRA, theregulation couldnot tahe effect untilithadbeen submitted tobothHouses ofCongress fora period of60 days ofcontinuous Congressional session, as definedby section 25(a)(4). Since itwas not possible topredict an exact date on whichthe Congressional review period would end, the preamble tothe final regulation statedthat EPA wouldissue a separate Federal Registernotice after thereview period was over announcing the effective date ofthe regulation. On November 10,1933, 60 days of continuous Congressional session elapsed.

Accordingly, the final regulation promulgated onJuly 26,1933 (48 FR 34000). became effective onNovember 10,1983. (Sec. 25, as amended.Pub.L 98-a39,94 Stat. 3195 (7U.S.C. 136))
