The US Army Corps of Engineers, Galveston District contracted ANAMAR to conduct a Sampling and Chemical Analysis and Bioassessment of the Gulf Intercoastal Waterway.
The U.S. Army Corps of Engineers, Galveston District is mandated to assess proposed dredged material discharge into ocean waters from federally authorized navigational channels. This evaluation aligns with Ocean Dumping and O&M Dredging Regulations. The EPA and USACE jointly established national guidelines, known as the “Green Book,” for testing dredged material. The Galveston District, in collaboration with the EPA, developed a Regional Implementation Agreement (RIA) for the Gulf of Mexico. According to the RIA, data over 5 years old may be insufficient, necessitating new sampling and analysis. Recent data from the Gulf Intracoastal Waterway project in Brazoria County, Texas, collected in October 2017 and analyzed in August 2018, indicates the need for sediment assessment. USACE Galveston District will analyze the results, considering relevant regulations, to determine the suitability of dredged material from the Gulf Intracoastal Waterway for ocean disposal in fiscal year 2023, supporting maintenance events through at least fiscal year 2028.
