Abstract: The NESHAP for Coke Oven By-Product Recovery Plants (40 CFR part 61, subpart L) were promulgated on September 14, 1989 (54 FR 38073) and amended on February 12, 1999 (64 FR 7458). These regulations apply to each of the following benzene emission sources at furnace and foundry coke by-product recovery plants: Tar decanters, tar storage tanks, tar-intercepting sumps, flushing-liquor circulation tanks, light-oil sumps, light-oil condensers, light-oil decanters, wash-oil decanters, wash-oil circulation tanks, naphthalene processing, final coolers, final-cooler cooling towers, and equipment intended to operate in benzene service, including: Pumps, valves, exhausters, pressure relief devices, sampling connection systems, open-ended valves or lines, flanges or other connectors, and other control devices or systems. The provisions of this subpart also apply to benzene storage tanks, BTX (benzene-toluene-xylene) storage tanks, light-oil storage tanks, and excess ammonia-liquor storage tanks at furnace coke by-product recovery plants. This information is being collected to assure compliance with 40 CFR part 61, subpart L.

The NESHAP for Benzene Emissions from Benzene Storage Vessels (40 CFR part 61, subpart Y) were promulgated on September 14, 1989 (54 FR 38077) and amended on December 14, 2000 (65 FR 78268). These standards apply to each benzene storage vessel with a design storage capacity greater than or equal to 38 cubic meters (10,000 gallons). This subpart does not apply to: (1) Storage vessels used for storing benzene at coke by-product facilities; (2) vessels permanently attached to motor vehicles—such as trucks, rail cars, barges or ships; and (3) pressure vessels designed to operate in excess of 204.9 kPa (29.72 psia) and without emissions to the atmosphere. This information is being collected to assure compliance with 40 CFR part 61, subpart Y.

In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.

Form Numbers: None.

Respondents/affected entities: Owners or operators of benzene storage vessels and coke oven by-product recovery plants.

Respondent's obligation to respond: Mandatory (40 CFR part 41, subparts L and Y).

Estimated number of respondents: 13 (total).

Frequency of response: Occasionally, semiannually, and annually.

Total estimated burden: 1,730 hours (per year). Burden is defined at 5 CFR 1320.3(b).

Total estimated cost: $201,000 (per year), which includes $0 in annualized capital/startup and/or operation & maintenance costs.

Changes in the Estimates: There is an adjustment decrease in the total estimated burden as currently identified in the OMB Inventory of Approved Burdens. This increase is not due to any program changes. Based on consultations with industry, the number of coke plants subject to Subpart L has been revised since the previous ICR, while the number of facilities subject to Subpart Y remains unchanged. The number of coke plants subject to Subpart L reflects a decrease in the number of operating coke by-product recovery plants. This change results in a decrease in both burden hours and the number of responses.
