NAME OF APPLICANT:  DISCOVERY PRODUCER SERVICES, LLC , c/o Perennial Environmental Services, 13100 Northwest Freeway, Suite 160, Houston, TX 77040.   

LOCATION OF WORK:  Located at 1474 LA Hwy 24, Larose, Louisiana, Latitude 29.541878, Longitude -90.395433, in Lafourche Parish, within the West Central Louisiana Coastal hydrologic unit (HUC 08090302), as shown on the attached drawings.                                                                                            

CHARACTER OF WORK:  The applicant has requested a Department of the Army authorization to clear, grade, excavate and deposit fill and/or aggregate material for the expansion of the Larose Gas Processing Plant. Approximately 172,785 cubic yards of a mixture of topsoil, concrete, stone/gravel material will be placed on-site for the plant expansion. The plant expansion includes the installation of a new 11,000-barrel slug catcher, the installation of a new 15,000-barrell per day condensate stabilizer, the removal of an existing levee, construction of a new permanent levee, temporary workspace and access roads, and the permanent fill of a pond. would be hauled in and deposited to achieve required grade elevation requirements.  The proposed project is situated on land adjacent to the existing Larose Gas Processing Plant and contains mixed-habitat wetlands.  It is anticipated that the proposed action would have minimal impact on adjacent wetlands outside of the project footprint with the use of best management practices.  

A preliminary analysis has determined that the proposed project would permanently impact 6.43 acres of wetlands of mixed habitat types. However, the exact extent of the coverage and impacts will be confirmed in a pending wetland determination.

The applicant claims avoided and minimized impacts on wetlands and non-wetland waters during the design phase of the project by modifying the slug catcher and condensate stabilizer configurations and selecting facility layouts that minimize the project footprint to the greatest extent practicable. The applicant states that they will purchase compensatory mitigation for permanent impacts to wetlands.
