SUPPLEMENTARY INFORMATION:

Title: National Emission Standards for Hazardous Air Pollutants,

Benzene Emissions from Benzene Storage Vessels, and Coke Byproduct

Recovery Plants--40 CFR Part 61, Subparts Y and L, OMB No. 2060-0185.

This is request for a revision of a currently approved collection.

Abstract:

Subpart L: Coke By-Product Recovery Plants

The standards require initial notification reports with respect to

construction, emissions tests, and startup; one-time reports on initial

performance tests; and periodic reports of emissions tests results.

Notifications inform the Agency or delegated authority when a

source becomes subject to the standard. The reviewing authority may

then inspect the source to check that pollution control devices are

properly installed and operated and the standards are being met.

Performance test reports are the Agency's record of a source's initial

capability to comply with the emission standard, and note the operating

conditions under which compliance was achieved. The regular reports are

used for problem identification, as a check on source operation and

maintenance, and for compliance determinations.

The Agency uses the information generated by the monitoring,

recordkeeping and reporting requirements to ensure that facilities

continue to operate the control equipment used to achieve compliance.

The information collected from recordkeeping and reporting requirements

is also used for targeting inspections, and is of sufficient quality to

be used as evidence in court. Based on reported information, EPA

decides how many plant inspections are needed, which plants to inspect,

and what records or processes to inspect at the plant. In the absence

of such information enforcement personnel would be unable to determine

whether the standards are being met on a continuous basis, as required

by the Clean Air Act.

Reporting requirements specific to benzene coke by-product recovery

plants, Subpart L, include a semiannual report by affected facilities.

The semiannual reports include results of leak monitoring and

performance tests. Respondents also are required to submit semiannual

reports of measurements for sources subject to a no detectable

emissions limit and semiannual reports summarizing the results of the

leak detection and repair program implemented at the plant. One report

would incorporate information for both process equipment and fugitive

sources. Exhausters are subject to quarterly monitoring requirements

unless the exhauster is equipped with a seal system that has a barrier

fluid, the exhauster seal is loaded and vented to a control device, or

a leakless exhauster is used.

The owner or operator choosing to use one of the alternative

control technologies (i.e., a carbon absorber or a vapor incinerator)

must record for the life of the control device, the design of the

control device, the sources which it is intended to control, and a plan

for the operation, maintenance and action needed to correct problems.

Such a record would assist the owner or operator to operate the device

properly throughout its life and would also assist the enforcement

personnel in determining whether the device had been properly

maintained and appropriate corrective action had been taken. The owner

or operator is required to record the results of each test for

determining compliance with the standard and any data that provide

reference values for parameters that are important to monitoring, such

as temperature of the firebox in a vapor incinerator and the benzene

concentration at the inlet to a carbon adsorber. Some of these data are

gathered during the compliance test, others separately (e.g., the

demonstrated bed life of a carbon adsorber).

The alternative control options also require reporting in

accordance with the General Provisions. These are submitted each time a

compliance test is performed. In addition, the rule requires reporting

of exceedances of the monitored parameters, with a brief description of

the corrective action taken.

Any owner or operator subject to the provisions of this part shall

maintain an up-to-date file of monitoring and recordings, and retain

them for at least two years following. Records of equipment and process

design are kept permanently.

Subpart Y: Benzene Storage Vessels

Respondents are all owners or operators of benzene storage vessels.

It is estimated that 126 existing plants are subject to the standard.

All owners and operators of new or reconstructed plants would also have

to respond.

In the General Provisions of 40 CFR Part 61 applicable to storage

vessels, require up to four separate one time-only reports for each

owner or operator: notification of construction or reconstruction,

initial source report, notification of physical/operational changes,

notification of anticipated and actual startup. The initial source

report is the only one of these reports that would be required from

existing sources under the standard.

Certain records and reports are necessary to assist EPA and State

agencies to which enforcement has been delegated in determining

compliance with the standard.

The standard is an equipment standard and owners or operators of

vessels equipped with the specified controls are required to submit,

along with the notifications required by the General Provisions, a

report that describes the control equipment used to comply with the

regulation. Thereafter, an annual visual inspection is required of the

primary seal of internal floating roof vessels (IFR's) (in cases where

no secondary seal is present, (An annual seal gap measurement of the

secondary seal system on external floating roof vessels (EFR's).) The

following

[[Page 24791]]

inspections are required every five years: (1) internal inspection to

seal system on IFR's equipped with primary and secondary seals in

situations where the owner to operator has decided to forego the annual

visual inspection; and (2) measurement of gaps between the tank wall

and primary seal on EFR's. An internal inspection in which the tank is

emptied and degassed is required at least every 10 years for IFR's.

Another control option allowed is for owners or operators to equip

vessels with closed-vent systems and 95-percent efficient control

devices. It is expected that very few, if any, vessels will be equipped

with these systems; however, owners or operators of vessels with such

systems are required to submit, for the Administrator's approval, an

operating plan describing system design specifications and an

operation, maintenance, and inspection plan for the system. In the

event the owner or operator has installed a flare, a report showing

compliance with visible emission provisions shall be furnished to the

Administrator. For closed-vent systems with control devices, quarterly

reports are required informing the Administrator of each occurrence

that results in excess emissions. Annual reports of the results of

these inspections and seal gap measurements are required. These reports

shall identify each storage vessel that is determined to be out of

compliance with the standard, the nature of the defects, and the date

the vessel was emptied or the repair was made. The owner or operator

must keep copies of all reports and records for two years.

The owner or operator of each benzine storage vessel shall, for the

life of the source, keep readily accessible records showing the

dimension of the vessel and an analysis showing the capacity of the

storage vessel. For each vessel with a closed vent system and 95-

percent efficient control device, records of the operating plan shall

be kept for the life of the control device. Records of monitored

parameters and maintenance shall be kept for two years.

An Agency may not conduct or sponsor, and a person is not required

to respond to, a collection of information unless it displays a

currently valid OMB control number. The OMB control numbers for EPA's

regulations are listed in 40 CFR Part 9 and 48 CFR Charter 15. The

Federal Register Notice required under 5 CFR 1320.8(d), soliciting

comments on this collection of information was published on September

28, 1995.

Burden Statement: The annual public reporting and recordkeeping

burden for this collection of information is estimated to average 11.85

hours per response. Burden means the total time, effort, or financial

resources expended by persons to generate, maintain, retain, or

disclose or provide information to or for a Federal agency. This

estimate includes the time needed to review instructions; develop,

acquire, install, and utilize technology and systems for the purposes

of collecting, validating, and verifying information, processing and

maintaining information, and disclosing and providing information;

adjust the existing ways to comply with any previously applicable

instructions and requirements; train personnel to be able to respond to

a collection of information; search data sources; complete and review

the collection of information; and transmit or otherwise disclose the

information.

Respondents/Affected Entities: 162.

Estimated Number of Respondents: 162.

Frequency of Collection: Quarterly and Semi-annual.

Estimated Total Annual Burden on Respondents: 8,628 Hours.
