   1. At 1030EDT 22Aug12, the NOAA SSC (NOLA) was contacted by USCG MSU Morgan City for trajectory support for a small (10gal/hr) submerged well/pipeline leak of S. LA Crude (API=36.2). Location of the leak is just off the SW Pass of the Mississippi R. delta. Leak is creating a "bright" (25%) to silvery (75%) sheen 1mi x 3/4mi in size. Source is at or just below the mudline in 250' of water at a production well leading to a pipeline. The responsible party, Walter Oil and Gas Co.,is in the process of securing the leak. Environmental conditions reported on site are current 0.5kt constant to the west, air temp=80F, winds 5-7kt from NW.
   2. THREAT: OIL. COMMODITY: SOUTH LA CRUDE, API=36.2. MAXIMUM POTENTIAL RELEASE: 500 GALLONS. TAGS: PIPELINE.

   Energy 21 Pipeline Leak W Delta31; Gulf of Mexico 30mi SE of Grand Isle, LA.
   Gulf of Mexico 30mi SE of Grand Isle, LA.
   1. At 2215EDT USCG Marine Safety Unit Morgan City, LA contacted the NOAA SSC requesting a trajectory for a crude oil pipeline leak. Maximum potential volume in the 10" by 1.3mi pipeline is 667BBL. However, the product in the pipeline is 80% produced water and 20% crude oil (API=30), so the estimated total potential oil spill is approx. 133BBL (5600gal). Leak location is approximately 16mi ESE of Grand Isle, LA, and 9mi SW of Pelican Isl, in Lease Block West Delta 31. The leak was creating a sheen of 1.75mi x 1.75mi when observed during an overflight at 1830CDT, with a coverage of 70% of variously: Metallic, Transitional, and Silver color.
   2. THREAT: OIL. COMMODITY: SOUTH LA CRUDE API 30 (20%) AND 80% PRODUCED WATER. MAXIMUM POTENTIAL RELEASE: 28014 GALLONS. TAGS: PIPELINE.
