NAME OF APPLICANT: Cameron Parish Port, Harbor and Terminal District, c/o Providence Engineering and Environmental Group LLC., Attn: Tim Kimmel, 1201 Main Street, Baton Rouge, LA 70802.
LOCATION OF WORK: Within the Calcasieu River Loop Pass, and within the Cameron Prairie National Wildlife Refuge, in Section 3 Township 14 South Range 9 West, in Cameron, Louisiana, in Ascension Parish, within the Calcasieu River Basin in hydrologic unit (HUC 08090100), as shown on the attached drawings (Latitude 29.806133°, Longitude 93.311181°).
CHARACTER OF WORK: The dredging work described herein was previously authorized under multiple permit authorizations, and time extensions that have been granted for dredging at and near the existing port facility since September 25, 2000. The most recent permit authorization was granted on July 14, 2011, for dredging of the channel to a depth of -30 feet to accommodate deep draft vessels and was extended on May 24, 2013. The applicant has requested to dredge 1,162,967 cubic yards of native material from the River bottom and then place this material strategically for use beneficially for marsh creation in open water areas on Cameron Prairie National Wildlife Refuge, totaling 1,121 acres. The material will be stacked to a height of approximately 1.5 feet to 2.0 feet NAVD 88 and allowed to settle to 1.0' NAVD 88 matching the natural elevation of the surrounding marsh. A 30-inch-diameter slurry line will transport the material from the dredge location to the refuge. The slurry line will be laid on the water bottom in the dredge area except for foreign pipeline crossings and at booster pumps. On land, the slurry line will be laid on top of the ground in an area previously utilized for the same purpose and then removed once the project is complete. In wetter sections, this area will be temporarily matted to reduce impacts to wetlands. No additional clearing is necessary and impacted access area will be allowed to revegetate upon disposal material completion.
