Dear Ms. Saginaw: POST OFFICE BOX 9400.t (504) 342-7015



### The State of Louisiana has approved and is submitting revisions to the Louisiana Operating Permits Program. On November 15, 1993, Louisiana submitted for your review the Operating Permits Program as mandated under Title V of the Clean Air Act Amendments of 1990. This revision package consists of two rules: (1) insignificant activities which will not require permitting in Louisiana; and, (2) edits to the Permit Procedures Rule as requested by EPA in the August 29, 1994 Federal Register.
The Louisiana Department of Environmental Quality considers this program revision to be a material revision, and requests that the Administrator extend the review period for the Louisiana Operating Permits Program in accordance with 40 CFR 70.4(e){2). The extension will allow the EPA to review the revisions and take final action on the Program with the revisions incorporated. For the smooth**i~plementation** 

### of this comprehensive new air quality permitting program, it is important that EPA not render the Program effective prior to review and approval of the submitted revisions.
Please contact the Air Quality staff .through Mr. Gus Von Bodungen, Assistant Secretary at (504) 765-0102 if you have any questions.

· Best wishes and warm personal regards.

This rule revises the Louisiana Air Quality Permit Procedures. The revision seeks to define Insignificant Emission Sources and to exempt such sources from the requirement to obtain a permit. Failure to promulgate this revision would result in the following types of emission
sources having to comply with obtaining a permit: miscellaneous equipment (maintenance or construction);

C. Internal Floating Roof. An internal floating roof consists of a pontoon type roof, double deck type roof or internal floating cover which will rest or float on the surface ofthe liquid contents and is equipped with a closure seal·to close the space betweenthe roofedge and tankwall. Alltank gauging and sampling devices shall be gas tight except when gauging or sampling is taking place. Each opening (except rimspace vents andautomaticbleedervents) shallbeprovided with a projection below the liquid surface. In addition, each opening (except for leg sleeves, bleeder vents, rim space vents, column wells, ladder wells, sample wells and stub drains) shallbeprovidedwith a coverequipped with a gasket. Automaticbleedervents and rimspace vents shall be gasketed and ladder wells shall be equipped with a sliding cover. This control equipment shall not be permitted if the org&.nic compounds have a vapor pressure of 11.0 pounds per square (- .· inchabsoluteorgreaterunderactual storageconditions.
