Do you have a Coastal Use Permit issued by DNR: Yes No If Yes, Please List your Coastal use Permit Number: 3. Are there any operations at the facility that may impact coastal waters such as any project involving dredge or fill, water control structures, bulkheads, oil and gas facilities, marina or residential development? Yes No If yes, you must contact DNR for a determination (888) 792-0432 or . I have contacted LDNR and this facility is not required to obtain a Coastal Use Permit. If a Coastal Use permit is required, an application was submitted on: SECTION III – DISCHARGE INFORMATION A. Provide the following discharge information: 1.

SECTION III – DISCHARGE INFORMATION (cont.) E. Outfall 004 - Complete Section III.E if sanitary waste is a contributing source of wastewater at this facility. Sanitary Waste: treated wastewater that contains human metabolic waste discharged from toilets and urinals. here if the sanitary waste outfall is not applicable to your operation. If not applicable, skip to the Outfall 005 discharge information section. 1. Give a brief description of the location of the sanitary waste outfall. For example, Outfall 004 is located at the point of discharge from the sanitary treatment unit located on the northeast corner of the production facility/platform. NOTE: This descriptive location should correspond with the location indicated on the facility site map. 2. List treatment method(s) used for the sanitary outfall: 3. List any pertinent physical and/or chemical properties of the discharge. (i.e., toxic components, taste and odor compounds, heavy metals, etc.) 4. Indicate how sanitary waste reaches state waters (named water bodies). This will usually be either “directly”, “open ditch” (if it is a highway ditch, indicate the highway), or by “pipe”. Please specifically name all of the minor water bodies that your wastewater will travel through on the way to a major water body. This information can be obtained from U.S.G.S. Quadrangle Maps. See Section VI. By (direct discharge, effluent pipe; etc.); thence into (The Gulf of Mexico; etc.) 5. Latitude/Longitude of Discharge: Latitude- deg. min. sec. Longitude- deg. min. sec. Method of Coordinate Determination: (Quad Map, Previous Permit, website, GPS) SECTION III – DISCHARGE INFORMATION (cont.) 6. Lab Analysis for Outfall 004 – Sanitary Waste - Sampling and analytical protocol must conform to the requirements found in 40 CFR Part 136. Provide analytical data for the following effluent characteristics for each sanitary waste outfall. If a treatment method is used, provide analytical data after treatment. Effluent Characteristic Effluent Analysis Concentration (mg/L) Mass (lbs/day) Monthly Average Daily Maximum Monthly Average Daily Maximum
Minimum Maximum Discharge Duration (hrs/day) pH (s.u.) Check here if requesting a waiver from any of the analytical data requirements above. If requesting a waiver, please provide justification for each applicable parameter. SECTION III – DISCHARGE INFORMATION (cont.) H. Outfall 007 - Complete Section III.H if miscellaneous discharges of wastewaters including desalinization unit discharge, diatomaceous earth filter media, blowout preventer fluid, uncontaminated ballast water, uncontaminated bilge water, mud, cuttings, and cement at the seafloor, uncontaminated freshwater, uncontaminated seawater, boiler blowdown, source water and sand, and excess cement slurry are contributing sources of wastewater at this facility. Desalinization unit discharge: wastewater associated with the process of creating freshwater from seawater. Diatomaceous Earth Filter Media: Filter media used to filter seawater or other authorized completion fluids that are subsequently washed from the filter. Blowout Preventer Control Fluid: fluid used to actuate the hydraulic equipment on the blowout preventer or subsea production wellhead assembly. Ballast Water: uncontaminated surface water used to maintain proper draft or to stabilize drilling or workover vessels. Bilge Water: water that accumulates in the bilge area of drilling or workover vessels. Muds, Cuttings, and Cement at the Seafloor: discharges which occur at the seafloor prior to installation of the marine riser and during marine riser disconnect and well abandonment and plugging operations. Uncontaminated Freshwater: freshwater which is discharged without the addition of chemicals. Included are: (1) discharges of excess freshwater that permit the continuous operation of fire control and utility lift pumps, (2) excess freshwater from pressure maintenance and secondary recovery projects, (3) water released during the training and testing of personnel in fire protection. Uncontaminated Seawater: is seawater which is returned to the sea without the addition of chemicals. Included are: (1) discharges of excess seawater which permit the continuous operation of fire control and utility lift pumps, (2) excess seawater from pressure maintenance and secondary recovery projects, (3) water released during the training and testing of personnel in fire protection, and (4) once through, noncontact cooling water which has not been treated with biocides.
