Louisiana SIP: LAC 33:III Ch 2107. Volatile Organic Compounds - Loading; SIP effective 2011-08-04 (LAd34) to 2017-09-27

Regulatory Text: 
Louisiana Administrative Code, Title 33 ENVIRONMENTAL QUALITY, Part III Air (LAC 33:III)

Chapter 21.  Control of Emission of Organic Compounds

Subchapter A.  General

Section 2107.  Volatile Organic Compounds - Loading.
As approved by EPA July 5, 2011 (76 FR 38977) effective August 4, 2011 (LAd34) LA021, Regulations.gov docket EPA-R06-OAR-2007-0924

Unless otherwise indicated, paragraphs are as approved by EPA 05/05/94 (59 FR 23166)  effective 06/06/94 (LAc60). 

   A. Applicability. The following loading facilities for volatile organic compounds having a true vapor pressure at loading conditions of 1.5 psia (10.3 kPa) or greater must comply with the requirements of Subsections B through F when servicing tanks, trucks or trailers which have individual capacities in excess of 200 gallons (760 liters):

       1. 20,000 gallons (75,700 liters) or more throughput per day (averaged over any 30-day period), for operations (all facilities on premises) for which construction commenced after May 20, 1979; or

       2. 40,000 gallons (151,400 liters) or more throughput per day (averaged over any 30-day period), for operations (all facilities on premises) for which construction commenced prior to May 20, 1979.  Once a facility is subject to this Section, it must remain in compliance with the requirements of Subsections B through F, even during periods in which its throughput is below the applicability levels.

   B. Control Requirements. The facility must be equipped with a vapor collection system properly installed, and in good working order.  The vapor collection system shall consist of, at a minimum, a vapor return line which returns to the VOC dispensing vessel or to a disposal system all vapors displaced during loading.  In the event a disposal system is used, it shall have a destruction/removal efficiency as referenced at Subsection E (demonstrated to the satisfaction of the Louisiana Department of Environmental Quality) of no less than 90 percent. Examples of vapor disposal systems include but are not limited to incinerators, flares, carbon adsorbers or chillers.
   Provisions must be made to prevent spills during the attachment and disconnection of filling lines or arms.  Loading and vapor lines must be equipped with fittings which close automatically when disconnected, or must be equipped to permit residual VOC in the loading line to discharge into a collection system or disposal or recycling system.

   C. Monitoring. No liquid or gaseous leaks shall exist during loading or unloading operations.  Inspection for visible liquid leaks, visible fumes, or significant odors resulting from VOC dispensing operations shall be conducted by the owner or operator of the VOC loading facility or the owner or operator of the tank, truck, or trailer.  VOC loading or unloading through the affected transfer lines shall be discontinued immediately when a leak is observed and shall not be resumed until the observed leak is repaired.

   D. Recordkeeping.  The owner or operator of any VOC loading facility shall maintain the following information on the premises for at least two years and shall make such information available to representatives of the Louisiana Department of Environmental Quality upon request:

      1. a daily record of the total throughput of VOC loaded at the facility; and

      2. for VOC loading operations subject to the requirements of this Section:

           a. a daily record of the number of delivery vessels loaded at the facility and the quantity and type of VOC loaded to each delivery vessel;

           b. a record of any leaks found at the facility in accordance with the provisions specified in Subsection C of this Section and the corrective action taken;

           c. a record of the results of any testing conducted at the facility in accordance with the provisions specified in Subsection E of this Section.

      3.  For vapor disposal systems, the following information shall be recorded:

           a.  daily measurements of the exhaust gas temperature immediately downstream of a direct-flame incinerator;

           b.  daily measurements of the inlet and outlet temperature of a chiller or catalytic incinerator; and

           c.  breakthrough of VOCs in a carbon adsorption unit.

      4.  The date and reason for any maintenance and repair of the applicable control devices and the estimated quantity and duration of volatile organic compound emissions during such activities shall be recorded.

   E. Test Methods. Compliance with Subsection B of this Section shall be determined by applying the following test methods, as appropriate:

AQ145   §2107.E.1;LAd34;LA021.02;AQ145;LR22:1212p6(12/20/1996)
      1. Test Methods 1-4 (40 CFR part 60, appendix A, as incorporated 
by reference at LAC 33:III.3003) for determining flow rates, as necessary;

AQ145   §2107.E.2;LAd34;LA021.02;AQ145;LR22:1212p6(12/20/1996)
      2. Test Method 25 (40 CFR part 60, appendix A, as incorporated 
by reference at LAC III.3003) for determining total gaseous nonmethane 
organic emissions as carbon.

   F. Exemptions.  This Section does not apply to a) crude or condensate loading facilities, b) ship and barge loading operations, and c) gasoline loading facilities which are regulated under Subchapter F.
