Waid Summary - Gas Distribution


NESHAP for Gasoline Distribution Facilities
Summary of National Emission Standards For Gasoline Distribution Facilities (Bulk Gasoline Terminals And Pipeline Breakout Stations) 40 CFR 63 Subpart R

Part 1. Introduction
Part 2. Applicability
Part 3. Standards


 1. INTRODUCTION:

Subpart R of 40 CFR Part 63 was promulgated on December 14, 1994 and amended on February 29, 1996 and February 28, 1997. This subpart governs emissions of hazardous air pollutants (HAP) from the gasoline distribution source category. The source category includes gasoline terminals and pipeline breakout stations. Affected facilities must comply with the equipment, monitoring, recordkeeping, and reporting requirements outlined below.


 2. APPLICABILITY:

§63.420(a) and (b):
The provisions of this subpart apply to each bulk gasoline terminal or pipeline breakout station, unless it can be shown that the facility is not a major source of HAP (emissions of greater than or equal to 10 tons/yr of any single HAP or greater than or equal to 25 tons/yr of total HAP) and is not located within a contiguous area and under common control of a facility that is a major source of HAP. Two methods are available to make this demonstration: the use of the appropriate emissions screening equation or performance of an emissions inventory for the facility.

§63.420(c)and (d):
If the screening equations are used to show that a source is nonmajor, the facility must be operated within the limits represented in the equation, based on a rolling 30-day average. The facility must also meet the recordkeeping and reporting requirements outlined (see section on Reporting and Recordkeeping).

§63.420(e):
The screening equations cannot be used to determine rule applicability by gasoline terminals or pipeline breakout stations that are located within a contiguous area and under common control with another gasoline terminal or pipeline breakout station or with other sources which emit HAP not included in the equations. EPA issued a direct final rule on February 28, 1997 which adds a factor to the equation for HAP emissions from other than gasoline operations (i.e. distillate, additives, etc.). This change allows use of the screening equation for many more facilities.

§63.420(g):
The owner or operator of a facility that is subject to the requirements of this subpart and provisions of 40 CFR 60 Subparts Kb or XX must comply with only the most stringent control requirements.


 3. STANDARDS:

Loading Racks
§63.422:

Gasoline loading racks at affected facilities must meet the requirements of §60.502 (VOC standards for gasoline terminals under NSPS Subpart XX) except that the emissions from vapor control system must not exceed 10 mg of total organic compounds per liter of gasoline loaded. Existing facilities must comply within 3 years of promulgation and new facilities must comply at startup. Controls are required for all cargo tanks (trucks and railcars) and all cargo tanks must be vapor tight.

Storage Vessels
§63.423:

Gasoline storage tanks at affected facilities with a design capacity of greater than or equal to 75 m3 ( 472 bbl) must meet the requirements of §60.112b(a)(1) through (4) (VOC standards for volatile organic liquid storage vessels under NSPS Subpart Kb) except that the deck fitting controls are not required. External floating roof tanks which have to add a secondary seal to meet the requirements must also add the deck fitting controls. Existing facilities must comply within 3 years of promulgation and new facilities must comply at startup.

Equipment Leaks
§63.424:

Equipment in gasoline service at affected facilities must be inspected monthly for leaks. Leak detection based on sight, smell, and sound is acceptable, and inspection must be performed during the loading of a gasoline cargo tank. A log book must be maintained which includes:

  • list or diagram of all equipment in gasoline service
  • inspector signature following each inspection
  • each detection of a leak

The initial repair attempt on all leaks is to be made within 5 days after detection, and completed within 15 days. If this is not possible, a demonstration must be made to the EPA Administrator to allow a delay in the repair.

Existing facilities were required to comply by December 15, 1997 and new facilities must comply at startup.

An instrument monitoring program may be approved by the EPA Administrator as an alternate program.

Gasoline is to be handled at the facility to minimize the opportunity for evaporative losses by minimizing spills and rapidly cleaning up those that occur, covering open gasoline containers with a gasketed seal, and minimizing gasoline sent to collection systems.

Test Methods and Procedures
§63.425
Loading Rack
§63.425(a):

The vapor control system must be tested to ensure compliance with the emission limitation of §63.422(b) following the procedures in NSPS Subpart XX (§60.503). For this rule, however, leaks of 500 ppm or greater in the vapor collection system shall be repaired.

§63.425(b):
Since continuous compliance must be demonstrated through a continuous monitor, the parameter value that indicates compliance must be determined for each performance test. For the operating parameter value to be approved by the EPA Administrator the rationale for its selection must be provided.

Storage Vessels
§63.425(d):

Affected storage vessels must meet the inspection requirements of §60.113b (NSPS Subpart Kb) for required seals and deck fittings.

Cargo Tanks
§63.425(e):

Cargo tanks must be checked annually to ensure vapor tightness following the procedure in 40 CFR 60 Appendix A, Method 27. The tank's internal vapor valve must also be checked following the procedure in the rule.

§63.425(f), (g), and (h):
The cargo tank and loading equipment are also subject to vapor tightness standards described in the rule, but no testing frequency is specified.

Continuous Monitoring
§63.427:

The vapor control system of all affected loading racks shall be equipped with a properly operated and maintained continuous monitoring system (CMS) as follows:

  • for carbon adsorption systems, the CMS shall measure VOC emissions in the stack
  • for refrigeration systems, the CMS shall measure temperature downstream of the condenser section or VOC emissions in the stack
  • for thermal oxidizers, the CMS shall measure temperature in the firebox or immediately downstream
  • for flares, a heat-sensing device shall be installed to detect the presence of a flame.

Alternative operating parameters may be approved by the EPA Administrator. The vapor control system must operate with the operating parameter within the established range. Failure to do so is considered a violation of the rule.

Affected storage vessels must comply with the monitoring requirements of §60.116b (NSPS Subpart Kb), except records must be kept for 5 years.

Reporting and Recordkeeping
§63.428

Existing facilities which are major sources of HAP or which use the screening equation to demonstrate area source status were required to submit their initial notification by December 16, 1996 or within 1 year from the date the facility becomes subject to this rule, whichever is later.

Affected facilities must keep records on annual certification testing and any continuous performance testing done on all cargo tanks which load at the facility. Information required to be included is listed in the rule.

The owner or operator of an affected loading rack shall keep a current and accessible record of all required CMS data. The data must be kept in a manner that shows when gasoline loading was taking place. Date and time of day shall also be indicated on the record.

Information on the selection of the operating parameter value must be included with the notification of compliance status.

Records for affected storage tanks must be kept as required under §60.115b (NSPS Subpart Kb), except records must be kept for 5 years.

Specific information (see §63.428(e)) on the nature of detected leaks is required to be maintained in the fugitive inspection log book.

All affected facilities must report to the EPA Administrator on the type, identification number, and location of all equipment in gasoline service. This report should be included with the initial notification for all existing facilities.

A semi-annual report must be submitted to the EPA Administrator for each affected facility. The report is to include the following information:

  • loading of each cargo tank without current vapor tightness documentation
  • reports required on storage vessel inspections under §60.115b
  • the number of equipment leaks not repaired within 5 days after detection.
